Nearly 60% of Americans Live with Pain

By Pat Anson, PNN Editor

Nearly 60 percent of U.S. adults have some type of short or long-term pain, according to a new CDC report that found the prevalence of pain steadily increases with age and is highest among adults aged 65 and older. Being female, white or poor also increased the likelihood of pain.

The CDC study is based on data from the 2019 National Health Interview Survey, in which participants were asked if they felt pain “some days,” “most days” or “every day” in the last 3 months.

Back pain (39%) was the most common site for pain, followed by pain in the hips, knees or feet (36.5%); hands, arms and shoulders (30.7%); and head pain (22.4%). About ten percent of those surveyed said they had abdominal or dental pain.

“Overall, nearly three in five adults (58.9%) experienced pain of any kind in the past 3 months in 2019,” researchers reported. “Location-specific pain, such as back, neck, arm, and hip pain is associated with short- and long-term health effects, ranging from minor discomfort to musculoskeletal impairment, diminished quality of life, and escalating health care costs.”

Household income appears to play a role in pain prevalence. Nearly 45% of people living in a household below the 2019 federal poverty level ($25,750 for a family of four) reported having back pain. For people with household income at least 200% higher, the rate of back pain was 37.6 percent. The association between pain and poverty was similar for people with pain in their upper and lower limbs.

The study findings are similar to the so-called “deaths of despair” first reported in 2015 by Princeton researchers Angus Deaton and Anne Case, who found that financial and emotional stress caused by unemployment and stagnant incomes may be behind the reduced life expectancy of middle-aged white Americans.

Between 1999 and 2013, the mortality rate for middle aged whites rose by 2 percent, coinciding with an increase in fatal overdoses. No other race or ethnic group saw such an increase in mortality. The rising death rate for whites was accompanied by more suicides and substance abuse, as well as increases in joint pain, neck pain, sciatica and disability.

One critic of the “deaths of despair” theory is Andrew Kolodny, MD, the founder of Physicians for Responsible Opioid Prescribing (PROP).  Kolodny in a recent webinar claimed that overdoses were driven by drug addiction, not socioeconomic factors.

“The deaths of despair framing, while provocative, is unlikely to explain the main sources of the fatal drug epidemic and that efforts to improve economic conditions in distressed locations, while desirable for other reasons, are not likely to yield significant reductions in drug mortality,” Kolodny said.

Kolodny and at least three other PROP board members have been well-paid expert witnesses in opioid litigation cases – lawsuits that depend on a public narrative that excess opioid prescribing led to the overdose crisis, not mental health problems or economic disparity. Maintaining that narrative is becoming harder, with opioid prescribing at 20-year lows and overdose deaths at record highs, fueled in part by economic and social issues exacerbated by the covid pandemic.

Spread of Delta Variant ‘Going to Get Worse’

By Liz Szabo, Kaiser Health News

Upon first inspection, the mutations in the highly contagious delta covid variant don’t look that worrisome.

For starters, delta has fewer genetic changes than earlier versions of the coronavirus.

“When people saw that the epidemic in India was driven by delta, they did not suspect it would be so bad or overtake other variants,” said Trevor Bedford, an evolutionary biologist at the Fred Hutchinson Cancer Research Center.

But those expectations were wrong.

Delta has kept some of the most successful mutations found in earlier variants, but also contains new genetic changes that enable it to spread twice as fast.

Delta is more dangerous in many ways. It has an incubation period of four days, rather than six, making people contagious sooner. When the pandemic began, people spread the original coronavirus to an average of two or three people. Today, people infected with delta infect six people, on average.

As of this week, the delta variant had caused at least 92% of the new infections in the United States, according to covariants.org, a research firm in Bern, Switzerland.

Although delta isn’t necessarily any more lethal than other variants, it can kill huge numbers of people simply because it infects so many more, said Dr. Eric Topol, founder and director of the Scripps Research Translational Institute.

Scientists have sequenced delta’s mutations but are still trying to understand their significance, said Angela Rasmussen, a virologist at the University of Saskatchewan’s Vaccine and Infectious Disease Organization. “When we see the same mutations appearing repeatedly and independently, that suggests they’re important,” Rasmussen said.

Scientists have the best understanding of mutations on the so-called spike protein — which sticks out from the surface of the virus like a club — and which have been studied the most intensely because of its serious ramifications, Rasmussen said. The coronavirus uses the spike protein to enter human cells, and changes in the spike can help the virus evade antibodies.

Scientists believe one of the most important areas of the spike is the receptor-binding domain, the specific part of the protein that allows the virus to latch onto a receptor on the surface of our cells, said Vaughn Cooper, a professor of microbiology and molecular genetics at the University of Pittsburgh. Receptors are like sockets or docking stations that allow proteins to interact with the cell. Once the virus gains entry to the cell, it can cause havoc, hijacking the cell’s genetic machinery and turning it into a virus-making factory.

Delta’s Worrisome Mix

Delta’s rapid spread is particularly surprising given it lacks two mutations that made earlier variants so scary.

Delta doesn’t have the N501Y spike mutation found in the alpha, beta and gamma variants, which enabled them to invade cells more successfully than the original virus. That mutation changed one amino acid — a building block of proteins — in the receptor-binding domain.

Delta also lacks the E484K mutation, which has made the gamma variant so worrisome. This genetic change, sometimes called “Eek,” allows the virus to spread even among vaccinated people.

Scientists use the Greek alphabet to name variants of concern. “The ‘D’ in delta stands for ‘different’ and a ‘detour’ to a different genomic mutation path,” Topol said. “But it doesn’t mean ‘doom,’” he said, noting that existing covid vaccines remain mostly effective against the delta variant.

Vaccines protect people from covid by providing them with antibodies that attach themselves to the spike protein, preventing the virus from entering cells. By dramatically reducing the number of viruses that enter cells, vaccines can prevent people from developing severe disease and make them less infectious to others.

Delta does share mutations with other successful variants. Like all the identified variants in circulation, delta contains a spike mutation called D614G, sometimes known as “Doug,” which became ubiquitous last year.

Scientists think Doug increases the density of spike protein on the surface of viral particles and makes it easier for the virus to enter cells.

Delta also has a spike mutation called P681R, which closely resembles a mutation in the alpha variant that appears to produce higher viral loads in patients, Cooper said. People infected with delta have 1,000 times more virus in their respiratory tract, making them more likely to spread the virus when they sneeze, cough or talk.

The P681R mutation, also found in the kappa variant, is located at the beginning of a part of the genome called the furin cleavage site, Cooper said.

Furin is a naturally occurring human enzyme that gets hijacked by the coronavirus, which uses it to slice the spike protein into the optimal shape for entering the cell, Rasmussen said. The new mutation makes that sculpting more efficient, Rasmussen said.

Another delta mutation — also found in kappa and epsilon — is called L452R. Experiments suggest this mutation, which also affects the receptor-binding domain, acts to prevent antibodies from neutralizing the virus, Cooper said.

These mutations appear to be more formidable as a team than alone.

The genetic changes “are certainly doing something, but why that combination makes the delta variant more fit is not entirely obvious,” Bedford said. “Putting them together seems to matter.”

Delta also has developed genetic changes not seen in other variants.

One such spike mutation is called D950N. “This might be unique,” Cooper said. “We don’t see that anywhere else.”

The D950N mutation is different than other mutations because it’s located outside the receptor-binding domain in an area of the coronavirus genome that helps the virus fuse with human cells, Cooper said. Fusing with human cells allows the coronavirus to dump its genetic material into those cells.

This mutation could affect which types of cells the virus infects, potentially allowing it to harm different organs and tissues. Mutations in this region are also associated with higher viral loads, Cooper said.

Delta also contains mutations in a part of the spike protein called the N-terminal domain, which provides a “supersite” for antibodies to latch onto the virus and prevent it from entering cells, said Dr. Hana Akselrod, an infectious diseases specialist at the George Washington University School of Medicine & Health Sciences.

Mutations in this region make monoclonal antibodies less effective in treating covid and increases the delta variant’s ability to escape vaccine-generated antibodies, Akselrod said. That may explain why vaccinated people are slightly more likely to become infected with delta, causing mostly mild illness but allowing them to transmit the virus.

Delta’s Future Course

Scientists say it’s impossible to predict exactly how delta will behave in the future, although Topol said, “It’s going to get worse.”

Topol noted that delta outbreaks tend to last 10 to 12 weeks, as the virus “burns through” susceptible populations.

If the United States continues to follow a pattern seen in the United Kingdom and the Netherlands, infections could rise from the current seven-day moving average of 42,000 cases to 250,000 a day. Yet Topol said the United States is unlikely to suffer the high death rates seen in India, Tunisia and Indonesia because nearly half the population here is fully vaccinated.

While some studies have concluded that the Johnson & Johnson vaccine stimulates strong and persistent antibodies against delta, a new report found that antibodies elicited by one shot may not be enough to neutralize delta. Authors of that study, from the New York University Grossman School of Medicine, suggested a second dose may be needed.

Two doses of the Pfizer-BioNTech vaccine protect 94% of people from any symptomatic infection by the alpha variant, compared with 88% against the delta variant, according to a new study in the New England Journal of Medicine. Two doses of the AstraZeneca vaccine protect 75% of people from alpha and 67% from delta.

Cooper said covid vaccines offer remarkably good protection. “I will always celebrate these vaccines as the scientific achievements of my lifetime,” he said.

The best way to slow down the evolution of variants is to share vaccines with the world, vaccinating as many people as possible, Bedford said. Because viruses undergo genetic changes only when they spread from one host to another, stopping transmission denies them a chance to mutate.

Whether the coronavirus evolves more deadly variants “is totally in our hands,” Cooper said. “If the number of infections remains high, it’s going to continue to evolve.”

By failing to contain the virus through vaccination, wearing masks and avoiding crowds, people are allowing the coronavirus to morph into increasingly dangerous forms, said Dr. William Haseltine, a former Harvard Medical School professor who helped design treatments for HIV/AIDS.

“It’s getting better, and we’re making it better,” he said. “Having half the population vaccinated and half unvaccinated and unprotected — that is the exact experiment I would design if I were a devil and trying to design a vaccine-busting virus.”

How Chronic Pain Disrupts Emotions

By Pat Anson, PNN Editor

Does waking up with pain everyday put you in a bad mood? Do you lose your temper easily or worry a lot?

It could be a sign that chronic pain has created a chemical imbalance in your brain that makes it harder for you to keep negative emotions in check, according to a new study by Australian researchers.

“Chronic pain is more than an awful sensation,” says senior author Sylvia Gustin, PhD, a neuroscientist and associate professor at the University of Sydney’s School of Psychology. “It can affect our feelings, beliefs and the way we are. 

“We have discovered, for the first time, that ongoing pain is associated with a decrease in GABA, an inhibitive neurotransmitter in the medial prefrontal cortex. In other words, there's an actual pathological change going on.”

Gustin and her colleagues at Neuroscience Research Australia (NeuRA) used advanced neurological imaging to scan the brains of 48 people. Half of them lived with a chronic pain condition, while the other half had no history of chronic pain and served as a control group.

Their findings, recently published in the European Journal of Pain, showed that participants with chronic pain had significantly lower levels of GABA than the control group – a pattern that was consistent regardless of the type of chronic pain. 

Neurotransmitters help communicate and balance messages between cells in the brain and central nervous system. While some amplify signals (excitatory neurotransmitters), others weaken them (inhibitive neurotransmitters). GABA, or γ-aminobutyric acid, is one of the latter. It acts in the brain as emotional regulator that helps dial down our emotions.

“A decrease in GABA means that the brain cells can no longer communicate to each other properly,” Gustin explained in a news release. “When there’s a decrease in this neurotransmitter, our actions, emotions and thoughts get amplified.”

While the link between chronic pain and decreased levels of GABA has previously been found in animals, this is the first time it’s been demonstrated in humans. Gustin hopes the findings will encourage people with chronic pain who may be experiencing mental health issues. 

“It's important to remember it’s not you – there’s actually something physically happening to your brain,” she says. “We don't know why it happens yet, but we are working on finding solutions on how to change it.”

GABA is not the only neurotransmitter that’s impacted by chronic pain. In a previous study, Gustin and her research team found that levels of glutamate, the main excitatory neurotransmitter, are also lower than average in people with chronic pain. Low glutamate levels are linked to increased feelings of fear, worry and negative thinking.

“Together, our studies show there's really a disruption in how the brain cells are talking to each other,” says Gustin. “As a result of this disruption, a person’s ability to feel positive emotions, such as happiness, motivation and confidence may be taken away – and they can’t easily be restored.” 

Medication can help relieve chronic pain, but there are currently no drugs that directly target GABA and glutamate levels in the brain. Gustin and her team are developing an online emotional recovery program as a non-pharmaceutical option for treating neurotransmitter disruption. 

“The online therapy program teaches people skills to help self-regulate their negative emotions,” says Gustin. “The brain can't dampen down these feelings on its own, but it is plastic – and we can learn to change it.”

FDA Approves Spinal Cord Stimulator for Diabetic Neuropathy

By Pat Anson, PNN Editor

Like many other people with diabetic neuropathy, Lee Cagle suffered from burning and stinging sensations in his legs – pain so severe that he used sheets at night to build a small tent around his feet so that the fabric didn’t touch his skin and trigger another flare.

The 33-year-old Arkansas man tried pain medications such as hydrocodone and gabapentin (Neurontin), but didn’t like their side effects or potential for addiction.

“I don’t want to get hooked on pain meds. I’ve seen people hooked on pain meds and I didn’t want that for myself,” Cagle told PNN. “I only used them on the worst of worse days, when I could not fall asleep because I was in so much pain.”

Last year Cagle heard about a clinical trial for people with painful diabetic neuropathy (PDN) and decided to take a chance, enrolling in the study to see if a Nevro spinal cord stimulator could relieve his pain. The device emits mild electrical pulses to disrupt pain signals before they reach the brain. 

“It was almost instantaneous. The ease of the pain that it gave me,” Cagle said. “I felt so much better.”

The results from his two-week trial were so promising that Cagle agreed to have the stimulator permanently implanted along his spine during an outpatient procedure. That was nine months ago.

“I’m a completely different person now, compared to what I was before I got it put in my back,” said Cagle, who had only one minor setback when one of the electrodes leading from the stimulator failed.      

Cagle was one of 113 patients with PDN who had Nevro stimulators implanted during the clinical trial. Several dropped out of the study due to adverse events such as infections and two had their devices removed.

Most of those who remained reported significant pain relief of at least 50% and improved quality of life.

NEVRO IMAGE

The overall results were so promising that the Food and Drug Administration recently approved Nevro’s Senza stimulators for the treatment of PDN, making it the only spinal cord stimulation system approved for that condition. The Senza stimulators are unique because they use high frequency electric pulses of 10 kHz, a frequency that doesn’t create an uncomfortable tingling sensation that’s common with other stimulators.

"The substantial pain relief and improved quality of life demonstrates that 10 kHz Therapy can safely and effectively treat this patient population," said lead investigator Dr. Erika Petersen, Professor of Neurosurgery and Director of Functional and Restorative Neurosurgery at the University of Arkansas for Medical Sciences. "I'm grateful to my co-investigators and the patients who participated in this study, as the results and this approval will have far-reaching impact on the lives of PDN patients."

‘Dangerously Lax’ Oversight

FDA approval of the Nevro stimulator for PDN is a significant expansion of the medical device market. Of the 34 million Americans with diabetes, about one in five have painful neuropathy, a condition that develops when high blood glucose levels damage peripheral nerves. Until now, most spinal cord stimulators were only approved for patients with severe back pain.

FDA approval also comes at a time when the agency is under growing scrutiny for its regulation of medical devices, particularly spinal cord stimulators. A 2020 report by Public Citizen accused the FDA of “dangerously lax” oversight of stimulators, which were linked to 156,000 injuries and 931 deaths. Ironically, the report noted that spinal cord stimulators are often touted as safer alternatives to opioid medication.  

“In the midst of the opioid crisis, medical device companies and medical centers that implant spinal cord stimulators increasingly have been marketing spinal cord stimulation as an alternative to opioids for chronic pain,” the report found. “Importantly, no evidence was provided that spinal cord stimulators reduce the use of opioids.”  

The FDA responded to the Public Citizen report by sending a letter to healthcare providers reminding physicians to only implant stimulators after a trial period that demonstrates the device provides effective pain relief. An FDA review of adverse events involving spinal cord stimulators found that nearly a third were reports of unsatisfactory pain relief. Even worse, the review identified nearly 500 deaths linked to the devices between 2016 and 2020.

A new study published this week in JAMA Internal Medicine concluded that the FDA’s adverse events reporting system for medical devices may significantly underestimate the number of deaths that actually occur. Researchers found the system relies too heavily on adverse events reported by device manufacturers.

The Center for Medicare Services (CMS) is also taking a harder look at spinal cord stimulators. On July 1, CMS implemented a new rule requiring Medicare patients to get prior authorization before a stimulator is implanted. The agency said there has been significant expansion in the use of spinal cord stimulators – about 50,000 are now implanted every year in the U.S. – but it could find no medical reason to justify the increasing number of procedures.

“After reviewing all available data, we found no evidence suggesting other plausible reasons for the increases, which we believe means financial motivation is the most likely cause," CMS said.

Industry groups and some members of Congress lobbied hard against the CMS rule, saying prior authorization would create “significant barriers to access to medically necessary procedures.”    

For patients who are desperate for pain relief, who find medication ineffective or difficult to obtain, spinal cord stimulation may be one of the few options remaining. Asked if he would recommend the Nevro stimulator to other DPN patients, Lee Cagle said he would.

“Definitely. Most definitely. I’m a totally different person now,” he said. “If Nevro came in with something else, if they needed me for a trial study, I wouldn’t hesitate.”  

Mission Creep and the CDC Opioid Guideline

By Roger Chriss, PNN Editor

It’s been over five years since the CDC released its opioid prescribing guideline for chronic pain. Now that the agency is looking at possible revisions, it’s worth taking a close look at what research is showing about the effects of the guideline.

First, let’s revisit the goals of the 2016 guideline:

“This guideline provides recommendations for primary care clinicians who are prescribing opioids for chronic pain outside of active cancer treatment, palliative care, and end-of-life care.

This guideline is intended to improve communication between clinicians and patients about the risks and benefits of opioid therapy for chronic pain, improve the safety and effectiveness of pain treatment, and reduce the risks associated with long-term opioid therapy, including opioid use disorder, overdose, and death.”

That’s not what has happened in practice. Instead, the CDC guideline has impacted pain management in both cancer and palliative settings, and has impeded access to care for people with chronic painful disorders.

Cancer and Palliative Care

Several major studies have appeared this year on the effects of the CDC guideline, all finding substantial and unexpected impacts on cancer and palliative care.

An Oregon State University study of over 2,600 hospital patients discharged to hospice care showed a decrease in opioid prescribing and an increase in the use of less powerful, non-opioid analgesics. As result, “some of those patients might have been undertreated for their pain compared to similar patients in prior years.”

Similarly, a study in The Oncologist looked at cancer patients with bone metastasis, and found that opioid prescribing fell significantly between 2011 and 2017. Researchers said their findings “raise concerns about potential unintended consequences related to population-level reduction in opioid prescribing.”

And a study in the journal Cancer found that in interviews with 26 patients with advanced cancer, the majority “experienced stigma about their opioid use for cancer pain management.” Patients also reported difficulties with pharmacies and insurance coverage of opioids.

Chronic Noncancer Pain Care

In chronic noncancer pain management, the CDC guideline has had mixed effects. A recent study in JAMA Network Open concluded that guideline-based opioid prescribing “has potential to improve pain management and reduce opioid-related harms,” but never addressed whether patients thought their pain care actually improved or was even adequate.  

The guideline has also had a chilling effect on some providers. A 2019 study in JAMA Network Open found that over 40% of primary care clinics in Michigan would not accept new patients being treated with opioids due to “decreased social desirability bias.”

The American Medical Association recently reported that many pharmacists have refused to fill legitimate opioid prescriptions, with some patients being told that they were not really in pain and others being subjected to “humiliating accusations that they were drug seekers.”

The AMA shared the experience of one doctor who came back from vacation to learn that he had been blacklisted by a major pharmacy chain that would no longer fill his prescriptions for controlled substances.

“When the CDC guidelines came down in 2016 basically saying we needed to take as many people as we could off opioids, I knew that my patients were in for a world of trouble,” said Aaron Newcomb, DO. “I was particularly concerned about my patients who were stable on low-dose opioid therapy for years. And my concerns have translated into an even worse reality for both me and my patients. Getting blacklisted by a national chain who had no clue about my practice was professionally wrong, but it also hurt my patients and my community.”

The goals of the CDC guideline were laudable. Improving patient outcomes and reducing public health risks are vital to the wellbeing of society. But at least so far, it’s hard to see the CDC guideline as having achieved any of its stated goals. Instead, we have guideline creep and a worsening overdose crisis.

The CDC alone should not be blamed for this outcome. States implemented laws and regulations, in some cases before the guideline was even released, that have contributed to these unfortunate shifts in clinical outcomes. The CDC even warned about misapplication of its guideline, though to little apparent effect.

There is clearly a lot of guideline creep at work. The impacts of the CDC guideline reach far beyond the use of opioids for chronic noncancer pain and are affecting patients in unintended ways, including those suffering from cancer and terminal illnesses or recovering from surgery. Patients and providers are hopeful the upcoming revision of the guideline will address these outcomes and improve pain care.

FDA Seeking Public Comments on Kratom

By Pat Anson, PNN Editor

The U.S. Food and Drug Administration is seeking public comments on the medical use and abuse of kratom. In a notice published Friday in the Federal Register, the FDA said the comments will be reviewed as it prepares a response to the World Health Organization (WHO), which is considering whether to place international restrictions on kratom and six other psychoactive substances.   

Kratom comes from the leaves of the mitragyna speciosa tree in southeast Asia, where it has been used for centuries as a natural stimulant and pain reliever. In recent years, millions of Americans have discovered kratom and use it to self-treat pain, anxiety, depression and addiction. The FDA has tried -- unsuccessfully so far – to schedule kratom as a controlled substance, which would effectively ban its sale and use in the United States.

Under international treaties, WHO is required to assess the use of psychoactive substances and advise the United Nations on whether they pose a public health risk and should be controlled. The annual assessment will begin in October and U.N. members have been invited to submit their recommendations.

Although the FDA said the U.S. will defer from making any immediate recommendations to WHO, the notice in the Federal Register makes plain that the agency still has a dim view of kratom. It makes no mention of the medical benefits many kratom users get from the herbal supplement.

“Kratom has a history of being used as an opium substitute in Southeast Asia. In the United States, kratom is misused to self-treat chronic pain and opioid withdrawal symptoms.”

— FDA

“Kratom is an increasingly popular drug of abuse and readily available on the recreational drug market in the United States. Evidence suggests that kratom is abused individually and with other psychoactive substances,” the FDA said.

“Kratom has a history of being used as an opium substitute in Southeast Asia. In the United States, kratom is misused to self-treat chronic pain and opioid withdrawal symptoms. Consumption of kratom can lead to a number of health impacts, including, among others, respiratory depression, vomiting, nervousness, weight loss, and constipation. Kratom has been reported to have both narcotic and stimulant-like effects.”

The American Kratom Association (AKA), a group of kratom vendors and consumers, said FDA instigated WHO’s review of kratom as a way to bypass the drug scheduling process in the U.S. The AKA is urging kratom consumers to submit positive comments about the herbal supplement.  

“The comments should be focused on the experiences that kratom consumers have had with kratom and how it has benefited them in terms of improving their quality of life, to reduce pain, to reduce anxiety and depression, to wean off of opioids, and how kratom has saved their lives,” Mac Haddow, an AKA lobbyist, said in a video. “We want the WHO to know the powerful experiences that people have had. We want to protect kratom, not only here in the United States, but also around the world.”

There’s an August 9 deadline for comments, which can be submitted here.

Asked if the FDA requested WHO to review kratom, a spokesperson told PNN the agency “does not determine for the U.S. government which substances shall be proposed” for review. WHO reviews can be requested by any member countries that are signatories to international drug control treaties.

Kratom’s legal status varies around the world. Thailand recently decriminalized kratom and will make the plants legal to grow and export in August. Kratom use is banned domestically in Indonesia, but kratom farming is still permitted. Most kratom exports come from Indonesia, where it is considered an important cash crop.

Kratom sales are legal in most U.S. states, although some states and communities have banned it. The FDA recently seized 37 tons of kratom from a vendor in Florida for alleged violations of a federal law that prohibits the sale of adulterated dietary supplements.

A federal effort in 2016 to ban kratom nationwide failed due to a public outcry. Two years later, the Department of Health and Human Services (HHS) withdrew a request to classify kratom as a Schedule I controlled substance, citing lack of evidence it can be abused or posed a public health threat. A top HHS official later said the FDA request to schedule kratom was rejected because of “embarrassingly poor evidence & data.”

AMA: Pain Patients ‘Need To Be Treated as Individuals’

By Pat Anson, PNN Editor

The American Medical Association is once again calling on the CDC to scrap dosage limits and make other changes to its controversial 2016 opioid prescribing guideline.

In a letter sent Thursday to a top official at the CDC’s National Center for Injury Prevention and Control (NCIPC), the chair of the AMA’s board of trustees said pain sufferers “need to be treated as individuals” and should not be subject to dose limits. The CDC is currently preparing a revision and possible expansion of the guideline, a lengthy process that could take another year to complete.

“A revised CDC Guideline that continues to focus only on opioid prescribing will perpetuate the fallacy that, by restricting access to opioid analgesics, the nation’s overdose and death epidemic will end. We saw the consequences of this mindset in the aftermath of the 2016 Guideline. Physicians have reduced opioid prescribing by more than 44 percent since 2012, but the drug overdose epidemic has gotten worse,” wrote Bobby Mukkamala, MD, a Michigan surgeon and chair of the AMA board.

The CDC said last week that a record 93,331 Americans died of drug overdoses in 2020. Although the vast majority of those deaths involved illicit fentanyl, heroin and other street drugs, efforts at combating the overdose crisis continue to focus on patients, doctors and reduced opioid prescribing.

“Patients with pain continue to suffer from the undertreatment of pain and the stigma of having pain. This is a direct result of the arbitrary thresholds on dose and quantity contained in the 2016 CDC Guideline. More than 35 states and many health insurers, pharmacies, and pharmacy benefit managers made the CDC’s 2016 arbitrary dose and quantity thresholds hard law and inflexible policy,” said Mukkamala.

“CDC’s threshold recommendations continue to be used against patients with pain to deny care. We know that this has harmed patients with cancer, sickle cell disease, and those in hospice. The restrictive policies also fail patients who are stable on long-term opioid therapy.”

The AMA has been warning about the “inappropriate use” of the guideline since 2018, when its House of Delegates adopted resolutions calling for the elimination of dose thresholds based on morphine milligram equivalents (MME). The CDC guideline recommends that daily doses not exceed 90 MME, a dose that some patients consider inadequate for pain relief.  

Recommendations a ‘Rough Guide’

At a meeting last week of the CDC Board of Scientific Counselors, one of the authors of the 2016 guideline said the MME thresholds were only meant to be “a rough guide” for prescribers and shouldn’t been seen as “absolutes.”

“We heard the concerning reports about the misapplication of the 2016 guideline and we’ve learned from what happened. We know there is a very real possibility that, even with adjustments, the guideline update could be misused,” said Deborah Dowell, MD, Chief Medical Officer of NCIPC.

Critics might wonder if the agency has learned anything in the last five years. A preliminary draft of a revised guideline still contains dose thresholds, recommending that doctors “should avoid increasing dosage to ≥90 MME/day or carefully justify a decision to titrate dosage to >90 MME/day.”

An independent panel of outside advisors that reviewed the draft expressed concern about maintaining the dose thresholds, saying they would lead to more forced tapering of patients.

“Though workgroup members recognized the need to have thresholds as benchmarks, many felt that including these thresholds in the supporting text could serve to de-emphasize them as absolute thresholds, and thus recommended removing the specific MME range from the recommendation,” the Opioid Workgroup said in its final report to CDC.

The workgroup also warned that the current draft revision of the guideline was “not balanced” because it focuses heavily on the risks and potential harms of opioids, with less attention paid to their potential benefits. The AMA called on the CDC to adopt the workgroup’s recommendations.

“Patients with pain need the CDC to be their advocate and urge it to rescind the perceived limits on opioid therapy doses or days,” Mukkamala said in closing his letter.

Opioid Income Redistribution

That view is not shared by the anti-opioid activist group Physicians for Responsible Opioid Prescribing (PROP), which sent out a news release this week claiming that prescription opioids are largely responsible for the overdose epidemic.

“Tragically, prescription opioids still account for about 28% of all opioid-related deaths.  Prescription opioids also contribute to synthetic opioid deaths because many heroin and illicit fentanyl users developed their addiction from taking prescription opioids,” PROP claimed. ”Overprescribing of opioids continues to fuel this epidemic. Reducing new opioid prescriptions remains vitally important.”

At least four PROP board members, including founder Andrew Kolodny, MD, have testified as paid witnesses for plaintiff law firms involved in opioid litigation, making as much as $725 an hour. Those law firms stand to make billions of dollars in contingency fees as those cases near an end, with one recent settlement expected to result in a $26 billion jackpot for states, cities and counties. As PNN has reported, many of the lawyers involved in the cases are major political donors.

“Businesses can’t print cash, so where do politicians think the money for these payoffs will come from? The answer is customers in higher prices and workers in lower wages,” The Wall Street Journal said in an editorial.

“The opioid settlement is another example in a growing list of lawsuits that redistribute income from the larger society to rich plaintiff attorneys, who then help politicians with their campaign contributions, who then rehire the lawyers to help with more mass tort claims. Alas, it’s the American way.”

Insomnia Drugs Risky When Taken With Opioids

By Pat Anson, PNN Editor

Medications commonly prescribed to treat insomnia significantly increase the risk of death for older adults if the drugs are taken with opioids, according to new study.

Zopiclone, zaleplon and zolpidem – collectively known as “Z-drugs” – are sold under brand names such as Ambien, Lunesta and Sonata. Z-drugs are sedative-hypnotics and act in a similar way as benzodiazepines, but are considered safer because they belong to a different class of medication.

But after reviewing the medical records of over 400,000 Medicare patients aged 65 and older, researchers at Vanderbilt University Medical Center found that Z-drugs are nearly as risky as benzodiazepines. Patients using benzodiazepines and opioids had a 221% higher risk of death from any cause, while those taking z-drugs and opioids had a 68% increased risk of dying.

Benzodiazepines such as Xanax and Valium are primarily used to treat anxiety. Until recently, benzodiazepines were often co-prescribed with opioids to pain patients, a practice that is now discouraged because both drugs suppress respiration, which can lead to an overdose.

"Our findings indicate that the risks of benzodiazepine-opioid use go well beyond the recognized hazards of overdose. They also suggest that the z-drugs, thought to have better safety than the benzodiazepines, in fact are dangerous when prescribed in combination with opioid pain medications," said Wayne Ray, PhD, professor of Health Policy at Vanderbilt and lead author of the study published in PLOS Medicine.

"Our findings add urgency to efforts to limit concurrent prescribing of benzodiazepines and opioids. They also suggest that targeted warnings are needed to advise older patients and their providers regarding the potential risks of taking z-drugs with opioids."

Last year the Food and Drug Administration ordering drug manufacturers to update warning labels for benzodiazepines to strongly caution patients and providers about the risk of abuse, addiction, dependence and overdose, particularly when the drugs are used with opioids or alcohol.   

In 2019, the FDA also ordered stronger warning labels for Z-drugs, but in that case it was to caution people about rare side effects such as sleepwalking, sleep driving and other risky behaviors.  

Can Psychedelics Be Used to Treat Fibromyalgia?

By Pat Anson, PNN Editor

A startup pharmaceutical company has announced plans for a clinical trial to see if a psychedelic compound may be useful in treating fibromyalgia.

California-based Tryp Therapeutics is partnering with scientists at the Chronic Pain & Fatigue Research Center at University of Michigan Medical School for the Phase 2a study, which would be the first to evaluate the effictiveness of psilocybin – the psychoactive compound in “magic mushrooms” -- in treating fibromyalgia.

"We are thrilled to collaborate with such forward-looking clinicians and scientists to develop additional treatment options for fibromyalgia," Jim Gilligan, PhD, Tryp’s President and Chief Science Officer said in a statement.

"The Chronic Pain & Fatigue Research Center at the University of Michigan brings incomparable experience with evaluating treatments for fibromyalgia and other chronic pain indications, and there is nothing more important to our collective team than creating therapies that will address the daily distress of these patients."

The study will evaluate the safety and efficacy of TRYP-8802, an oral formulation of synthetic psilocybin developed by Tryp. The treatment, which will also include psychotherapy, is designed to target pain through neuroplasticity, which alters and reorganizes neural networks in the brain.

Fibromyalgia is a poorly understood disorder characterized by widespread body pain, fatigue, poor sleep, anxiety and depression. Standard treatments for fibromyalgia, such as non-steroidal anti-inflammatory drugs (NSAIDs) and gabapentinoids (Lyrica, Neurontin), often prove to be ineffective or have unwelcome side effects.

"Existing treatment options for fibromyalgia are often ineffective and show significant side effects," said Daniel Clauw, MD, Director of the Chronic Pain & Fatigue Research Center.

Tryp plans to submit an Investigational New Drug application to the FDA for the Phase 2 trial in September. Phase 2 studies typically involve a few hundred people with a disease or condition, and are designed to test the safety and efficacy of a treatment.  A much larger Phase 3 study is usually required before the FDA will even consider approval.

Interest in using psychedelics to treat medical conditions has been growing in recent years, primarily as a way to treat depression, anxiety and other mental health issues. Preliminary research suggests that microdoses of LSD, psilocybin and other psychedelics may also be effective in treating pain.

Another pharmaceutical startup – Mind Medicine (MindMed) – recently announced plans to  investigate LSD as a treatment for cluster headache and an unnamed “common, often debilitating, chronic pain syndrome.”

Tryp Therapeutics is focused on developing psilocybin-based compounds for the treatment of diseases with unmet medical needs. The company recently announced a partnership with the University of Michigan to study synthetic psilocybin as a treatment for neuropsychiatric disorders. Tryp is also working with the University of Florida to investigate psilocybin as a treatment for eating disorders.

LSD, psilocybin and other psychedelics are classified as Schedule I controlled substances, meaning they have a high potential for abuse and currently have no accepted medical use in the United States.

Rare Disease Spotlight: Transverse Myelitis

By Barby Ingle, PNN Columnist  

This month as part of my series on rare diseases and conditions, we’ll look at transverse myelitis (TM), an inflammatory disease of the spinal cord. TM causes pain, muscle weakness, numbness, tingling, and bladder and bowel dysfunction. Severe cases can even result in sudden paralysis. 

Can you imagine being fine one minute and the next being paralyzed and losing control of your bowels?

The most famous person I have heard of having transverse myelitis is Allen Rucker, an author and comedy writer who developed TM spontaneously at the age of 51. Rucker wrote a memoir about becoming paralyzed due to TM: “The Best Seat in the House: How I Woke Up One Tuesday and Was Paralyzed for Life.”

As with many TM patients, Rucker was paralyzed from the waist down and has no control over his legs, bladder or bowel. He will need a wheelchair for the rest of his life. Despite these challenging conditions, Rucker continues to write and uses his communication skills to help others understand what it is like to live with a rare disease.

Transverse myelitis can occur at any age, but most often affects patients between the ages of 10-19 and 30-39. Some people do recover from TM, but the process can take months or even years. Most see improvement in their condition within the first 3 months after the initial attack, giving them a good idea of what they will face long-term.

There are many different causes of transverse myelitis, including viral, bacterial or fungal infections that attack the spinal cord. The inflammatory attack usually appears after recovery from an infection, such as chickenpox, herpes or shingles. TM can also be caused by immune system problems or myelin disorders, such as multiple sclerosis.

Patients who develop transverse myelitis can go through many treatments, including intravenous steroids for days to weeks at a time, plasma exchange therapy, antiviral medication, pain relievers, and drugs used to treat complications. There are some preventative medications to help keep inflammation down, avoid new flares and long-term complications.  

A patient can expect to undergo multiple MRIs of the spine as well as blood testing and possibly a spinal tap to check cerebrospinal fluid. They may also be started on physical therapy, occupational therapy and psychotherapy.

It can be difficult to know the course an individual with TM might take, but they fall into three areas: no or slight disability, moderate disability and severe disability.  The sooner that proper treatments begin for TM, the better the outcomes can be.

If you suspect you might have TM, keep track of when the symptoms started, what they are and how fast they progressed. Note if they presented through pain, tingling or other unusual sensations such as loss of bladder and bowel control or difficulty breathing. A provider will also want to know if you have recently traveled or had any infections or vaccinations.

If you are diagnosed with transverse myelitis, you can find support at the Siegel Rare Neuroimmune Association, a non-profit that advocates for people with TM and other neuroimmune disorders. They are a great resource for those who need assistance for research and daily living. Facebook also has several TM support groups, such as Transverse Myelitis Folks and Transverse Myelitis Society.

We are now halfway through our series on rare diseases and conditions. So far, I have covered transverse myelitis, Paget’s disease, Alexander disease, X-linked Hypophosphatemia, cauda equina syndrome, vulvodynia and Dupuytren's contracture. Next month I will look at Friedreich’s Ataxia.

Terpenes Make Cannabis More Effective as Pain Reliever

By Pat Anson, PNN Editor

A new study may help explain what makes cannabis effective as a pain reliever. It’s not just cannabinoids like cannabidiol (CBD) or tetrahydrocannabinol (THC), but terpenes -- the aromatic compounds that give cannabis its distinctive “skunky” smell. The finding could lead to new ways to boost the potency of cannabis, opioids and other pain-relieving drugs without increasing the dosage.

In experiments on laboratory rodents, scientists at the University of Arizona Health Sciences found that Cannabis terpenes, when used alone, mimic the effects of cannabinoids, including a reduction in pain sensation. When terpenes were combined with a synthetic cannabinoid, the pain-relieving effects were amplified – an “entourage effect” – that reduced pain levels without an increase in euphoria and other side effects.

"A lot of people are taking cannabis and cannabinoids for pain," said lead researcher John Streicher, PhD, a member of the UArizona Health Sciences Comprehensive Pain and Addiction Center and associate professor of pharmacology at the College of Medicine-Tucson.

"We're interested in the concept of the entourage effect, with the idea being that maybe we can boost the modest pain-relieving efficacy of THC and not boost the psychoactive side effects, so you could have a better therapeutic."

Terpenes are found in many plants and are the main component in essential oils. The terpene linalool gives lavender its distinctive floral scent, while citrus trees get their smell from the terpene limonene. Plants create terpenes to lure pollinators, such as birds and insects, and to protect themselves from predators.

Streicher and his colleagues focused on four Cannabis terpenes: alpha-humulene, geraniol, linalool and beta-pinene. They evaluated each terpene alone and in combination with a synthetic cannabinoid that stimulates the body's natural cannabinoid receptors.

In laboratory experiments, researchers found that all four terpenes activated a cannabinoid receptor in the brain, just like THC. The behavioral studies in mice also revealed the terpenes lowered pain sensitivity, reduced pain sensation, lowered body temperature, and reduced movement and catalepsy, a freezing behavior related to the psychoactive effects of cannabinoids.

When terpenes were combined with the synthetic cannabinoid, researchers saw a greater reduction in pain sensation -- demonstrating a terpene/cannabinoid interaction in controlling pain.

"It was unexpected, in a way," said Streicher. "It was our initial hypothesis, but we didn't necessarily expect terpenes, these simple compounds that are found in multiple plants, to produce cannabinoid-like effects."

The study findings were recently published in the journal Scientific Reports. Streicher and his research team still need to confirm if terpenes have an entourage effect when combined with THC and other naturally occurring cannabinoids. Their long-term goal is to develop a dose-reduction strategy that uses terpenes in combination with cannabinoids or opioids to achieve the same levels of pain relief with fewer side effects.

Although the therapeutic benefits of terpenes are not well understood, some cannabis companies are already incorporating them into their products. Lemon Kush, for example, is a hybrid marijuana strain that contains limonene, while the hybrid Blue Dream has a terpene found in blueberries. Terpenes are also being added to chocolate, beverages and many other consumer products.  

Being Judged for My Invisible Disability

By Victoria Reed, PNN Columnist

One of the things that irritate me is when people have complete disregard for disability parking spaces and park in them without a permit.

Recently, my family and I traveled to another state for a wedding. While we were there, we decided to check out a popular outdoor tourist attraction. Being that it was a weekend, the attraction was quite crowded. As we entered the parking lot, it was clear that we would either need to wait for a parking space or leave altogether. We decided to take our chances and wait.

Then I noticed a car parked in one of the disability spaces without the required permit. While the car had been ticketed by the National Park Service, I was a little annoyed because I have a disability placard (prescribed by a rheumatologist), and we could have parked in that space. Or someone else who is disabled could have.

My disability placard has been invaluable to me over the years, as I suffer from at least two of the “invisible” illnesses—rheumatoid arthritis and fibromyalgia. On days when my RA or fibromyalgia is at its worst, I utilize the placard and park in a space that would help minimize my walking distance. Sometimes both conditions work in-tandem to make my life miserable, causing joint pain and muscle pain/weakness.

I know I may not look disabled on some days. I try to put myself together before going out (no offense to those who are unable to), and I don’t use a wheelchair, scooter, cane or walker on a regular basis. I have used wheelchairs and electric scooters in the past while attending sprawling places like Universal Studios, zoos or other venues with my kids or where there would be significant walking involved.

Because I often don’t appear like a person who is disabled, I have received the “looks” from people when exiting my car after parking in a disabled parking space. I’ve also gotten nasty stares when I pull in and don’t hang my disability parking tag right away.

I wish that people would not be so judgmental, but sadly, some are! You never know what a person might be struggling with that’s not readily apparent. I always try to keep that in mind. If a person doesn’t use assistive devices, it doesn’t necessarily mean that they are not needed or mean that a person is completely well. 

Not only is the pain of RA and fibromyalgia a significant issue for me, so is the profound fatigue that accompanies both of these conditions. Some days, even if I’m not having active joint or muscle pain, the fatigue can be nearly incapacitating and make walking (or doing just about anything) difficult. In addition, the fatigue causes shortness of breath. People can’t usually see that.

Another thing that I’ve noticed in this Covid era is the decrease in disability parking spaces as retailers reassign those spaces for drive-up purchase pickup. I don’t have a problem with the drive-up spaces, as I often use them myself on more difficult days, but it’s a little concerning when disability parking spaces are reduced in favor of those. On better days, I like to park and go into stores because moving my body is good for me, regardless of the pain and/or fatigue I might be experiencing that day.

Hopefully, if Covid-19 ever completely goes away, retailers will add back those disability parking spaces that they took. We need those spaces!

It’s possible that someday I might need the regular use of a cane, walker or wheelchair, but until then, having an invisible illness and parking in a disability space will probably get more negative attention than it should. Yes, it bothers me when people judge me and assume that I don’t have a disability, but I will continue to keep my head up and go about my business.

As a chronic pain patient, I’ve learned to be tough, and I’ve had to develop a thick skin about be judged. Their problem is not my problem. However, my problem could someday become their problem! We are all just one accident, injury or illness away from possible disability. 

As for a parking space at that tourist attraction, we got one after about a 10 minute wait. I can’t complain too much about that!

CDC Advisory Panel Warns Revised Guideline Ignores Benefits of Opioids

By Pat Anson, PNN Editor

An independent advisory panel is warning the CDC that a draft revision of its 2016 opioid guideline is focused too heavily on the risks of taking opioid medication, with not enough attention paid to the benefits that opioids have for many pain patients.

A 12-page report from the CDC’s Opioid Workgroup was discussed Friday during an online meeting of the agency’s Board of Scientific Counselors (BSC). The 23-member workgroup is composed primarily of physicians, academics and researchers involved in pain management, including some who advised the agency during the drafting of the original guideline.

CDC has not made public the revised draft guideline and has no plans to release it for public comment until later this year. The workgroup, however, has seen the draft and many of its members have issues with it.     

“Overall, many workgroup members felt that much of the supporting text of the guideline was not balanced and was missing key studies. Many workgroup members felt that the guideline focused heavily on the risks or potential harms of opioids, while less attention was focused on the potential benefits of opioids, or the risk of not taking opioids or undertreating pain,” the workgroup report states.

“Many workgroup members noted how the guideline has a constant tension between public health benefits versus patient benefits. This issue is minimally addressed in the guideline and comes very late. Workgroup members felt it is important to directly address this tension between risks and benefits to public health versus individual patients.”

Although voluntary and only intended for primary care physicians treating chronic pain, the 2016 guideline’s recommended dose limits for opioids were quickly adopted as policy by many states, insurers, law enforcement, pharmacies and doctors of all specialties.

As a result, many pain patients who took opioids safely for years were cutoff or tapered to lower doses. Many new patients who need pain relief can’t even get opioids because their doctors refuse to prescribe them. Opioid prescriptions have fallen to their lowest level in 20 years, but drug deaths continue rising.

Not until 2019 did the CDC publicly acknowledge the “misapplication” of the guideline and promise to make changes – although the process is unfolding slowly. The newly revised guideline is not expected to be released until late 2022.

“We heard the concerning reports about the misapplication of the 2016 guideline and we’ve learned from what happened. We know there is a very real possibility that, even with adjustments, the guideline update could be misused.”

— Dr. Deborah Dowell, CDC

“We heard the concerning reports about the misapplication of the 2016 guideline and we’ve learned from what happened. We know there is a very real possibility that, even with adjustments, the guideline update could be misused,” said Deborah Dowell, MD, Chief Medical Officer of the CDC’s National Center for Injury Prevention and Control (NCIPC), who co-authored the original guideline.

Dowell gave a brief outline of the guideline update to the BSC, noting that it’s recommendations are being expanded beyond chronic pain to include acute pain (pain lasting less than one month) and sub-acute pain (pain lasting 1 to 3 months).

She also disclosed the names of the five co-authors who are writing the update, briefly showing their names on a slide. They include Dowell herself, Kathleen Ragan, a CDC Health Scientist; Christopher Jones, PharmD, Acting Director of NCIPC; Grant Baldwin, PhD, Director of Overdose Prevention at NCIPC; and Roger Chou, MD, Director of the Pacific Northwest Evidence-based Practice Center at Oregon Health & Science University (OHSU), which has received billions of dollars in research funding from the federal government.

The inclusion of Chou as an update co-author is likely to be controversial. As PNN has reported, Chou has been an outspoken critic of opioid prescribing and has numerous ties to Physicians for Responsible Opioid Prescribing (PROP), an anti-opioid activist group. Like Dowell, Chou was a co-author of the 2016 guideline.

“It is wildly inappropriate and unethical that someone with strong ties to the anti-opioid industry and who has significant financial conflicts of interest is leading this process,” Amy Partridge, an intractable pain patient, told the BSC. “The evidence review and guidance are therefore both inherently biased and should be struck in their entirety.”

Chou — who is a member of the BSC — acknowledged he has a conflict of interest at the start of the meeting and recused himself. “I do have a conflict. I receive funding to conduct reviews on opioids, and I'll be recusing myself after the director's update,” said Chou.

Chou’s recusal apparently only applied to his participation in the meeting, not to his continuing involvement in the guideline update or OHSU’s research.

Dose Recommendations Questioned

Some members of the Opioid Workgroup feel the current draft of the update is “not sufficiently patient-centered,” while others believe not enough attention was paid to disparities in pain care and lack of access to effective, non-opioid treatments.

One of the biggest issues for the workgroup is the revised guideline’s recommendation that initial opioid doses be limited to 50 morphine milligram equivalents (MME) per day and not be increased above 90 MME, which is essentially unchanged from the 2016 guideline. The workgroup believes the dose thresholds are arbitrary, based on poor evidence and should be “de-emphasized.”

“Many workgroup members voiced concern about the dose thresholds written into the recommendation. Many were concerned that this recommendation would lead to forced tapers or other potentially harmful consequences. Though workgroup members recognized the need to have thresholds as benchmarks, many felt that including these thresholds in the supporting text could serve to de-emphasize them as absolute thresholds, and thus recommended removing the specific MME range from the recommendation,” the report found.

Dowell said the MME thresholds are only meant to be “a rough guide” and shouldn’t been seen as “absolutes.”

“We certainly are looking at language in the guideline and also looking at feedback about how to better communicate those nuances and their flexibility,” she told the BSC.

Worries About ‘Bad Policy’

Several workgroup members have issues with the recommendation that non-opioid therapies be used for “many common types of acute pain,” because it doesn’t distinguish between post-surgical pain that may require opioids and other types of short-term trauma that could be treated with non-opioid pain relievers. They warned the recommendations for treating acute pain “could be misinterpreted and translated into bad policy.”

The workgroup also took issue with recommended drug testing for anyone prescribed opioids for chronic pain. Their report says false results from urine drugs tests are common and could have “inappropriate negative consequences” for patients, while more accurate and expensive laboratory tests may not be covered by insurance.

Questions were also raised about prescription drug monitoring programs (PDMPs), particularly the use of algorithms and data mining to create risk scores for patients based on their drug history.

It's important to note that the workgroup’s role is strictly advisory. It had no direct role in writing the revised guideline and will not be involved in rewriting it, if changes are even made.

You can watch most of the meeting below (video courtesy of Peter Pischke):

The workgroup’s report drew both criticism and praise during the public comment period. Some speakers believe the guideline can’t be fixed and should be repealed.

“No matter the intent, goal or method that the CDC may desire with these guidelines and their purpose in the American healthcare system, the DEA will still manipulate them to serve their way,” said Margaret Rene Blake, a pharmacist and intractable pain sufferer. “As long as they exist, they can and will be misapplied. The way to stop the harm to patients, providers and the system is to repeal the guideline.”

One critic suggested the workgroup volunteers, who were unpaid, were swayed by the pharmaceutical industry.

“The OWG (Opioid Workgroup) comments perpetuate myths disseminated by opioid manufacturers. Claiming that the guideline focused heavily on the risks or potential harms of opioids, while less attention was focused on the potential benefits is certainly an industry friendly view,” said Adriane Fugh-Berman, MD, Director of PharmedOUT and a PROP board member, who was a paid expert witness in Oklahoma’s lawsuit against opioid manufacturers.

“Several statements in the OWG (report) are just wrong, including the claim that continuing and not tapering opioids avoids risks of poor analgesia, worsening function and suffering.”

Without seeing the revised draft guideline in its entirety, it’s hard to tell if any significant changes have been made to the original guideline. But judging from the workgroup’s report, the changes have been minor so far. The draft guideline continues to maintain that “nonopioid therapies are preferred” for both short and long-term pain, and that doctors should only consider opioids “if expected benefits for pain and function are anticipated to outweigh risks to the patient.”

There is also no indication what the CDC intends to do to persuade states, insurers, pharmacies, doctors and other federal agencies that they should amend opioid policies and laws that are based on the 2016 guideline.

A Matter of Interpretation

By Carol Levy, PNN Columnist

I recently read a post in one of the online chronic pain support groups. “Sue” had just left an appointment with her pain management doctor. She was enraged, so angry about the way the meeting had gone, that she went right to her computer and complained about it.  

“My doctor asked, ‘What do you think about my lowering the pain meds you're on?’” Sue wrote.

“How dare he reduce them!” was her response. Sue said the medications were helping her and the doctor had some nerve to ask. All these doctors want to do is hurt us, she wrote, and if it wasn't for the CDC and FDA, this wouldn’t be happening.

I read her post and was somewhat confounded by her anger. She did not include any information on how the meeting ended. Did he lower her dosage or the number of pills? I could see how upset that would make someone, especially if the drugs were helping.

But he didn't say, “I am going to lower the level of opiates I am giving you.” He said it in a way that seemed, to me, like he meant to open a discussion.

It reminded me of a difficult crossword puzzle I had just completed. It was so frustrating. I had it all done, but for one four-letter word. The clue was “wind.” All I could think of was “blow,” as in the wind blowing, but the letters didn’t fit.

There was a “C” for the first letter but I could not think of one word that started with “C” that fit the clue. No matter what letters I tried, I could not think of any other answer but “blow.”

Finally, I was able to figure out the word. The answer was “coil.”  

“Coil,” I thought. “Oh, for goodness’ sake.”

I was so obsessed with my one interpretation, it never occurred to me to consider another. It wasn't wind, as in the wind blows. It was wind, as in winding a clock or a windy road.

I think we do this often, and not just with medical people. They make a statement or ask a question that seems clear. But to the listener it carries a whole different meaning.

It’s harder when you're right there. Reading about it online made it easier for me to see it as the doctor asking, not demanding or insisting. In the heat of the moment, it may well sound like, “I'm not going to help you anymore. I'm stopping the drugs that have been helping you.”

There are crosswords and cross words. Sometimes we have to stop, take a deep breath, and instead of responding with angry or impulsive words, ask for an explanation.

“Are you asking me about lowering my meds or are you telling me you will?”

 If it’s the latter, it may well be the time to be upset. If it’s the former, it’s time to open the discussion.

A New Option for Young Migraine Sufferers

By Pat Anson, PNN Editor

Migraines can have a devastating impact on children and adolescents. In addition to causing head pain, upset stomachs and visual disturbances, migraine attacks can disrupt school and social activities at a sensitive time in a young person’s life.

Although pediatric migraines are common, affecting about 10% of school-age children and one in five teenagers, treatment options are very limited compared to adults. There are no FDA approved pharmaceutical migraine treatments for kids under the age of 12. That leaves doctors to prescribe migraine medication to children off-label, including a new class of migraine drugs called CGRP inhibitors, which have not yet been approved or studied in young children. 

A small new study suggests there may be a safer and more effective option for young migraineurs: neuromodulation. Research recently published in the journal of Pain Medicine found that Nerivio, a neuromodulation device worn on the upper arm, was more effective in treating acute migraine in adolescents than triptans and over-the-counter pain relievers. Nerivio uses smartphone-controlled electrical pulses to stimulate nerves and disrupt pain signals.

“To my knowledge, this is the first study that directly compared remote electrical neuromodulation and standard-care treatment options in adolescents,” says lead author Andrew Hershey, MD, co-director of the Headache Center at Cincinnati Children’s Hospital Medical Center.

“Migraine in adolescents is associated with poorer performance and absence from school and social activities during a particularly formative time in life. Providing teens with more effective and engaging treatments for migraine can have far-reaching positive effects over the course of their lives.”

Nerivio was developed by Theranica, an Israeli medical technology company that sponsored the study. The FDA approved the device as a treatment for acute migraine in adults in 2019 and recently expanded the label to include children over the age of 12 with episodic or chronic migraine.

THERANICA IMAGE

Thirty-five adolescent migraine patients aged 12 to 17 took part in the two-month comparison study. Over-the-counter drugs and oral triptans were used by patients during the medication month, and Nerivio during the Remote Electrical Neuromodulation (REN) month.

Two hours after treatment, over a third (37%) of patients achieved complete pain freedom during the REN phase of the study, compared to just 8.6% in the medication phase. Some degree of pain relief was reported by 80% of patients in the REN phase, as opposed to 57% in the medication phase.

“This study provides evidence that Nerivio may be considered as a first-line acute treatment, especially for adolescents with medication restricting comorbidities or a preference for a non-medication-based treatment,” said co-author Samantha Irwin, MD, a pediatric neurologist at the UCSF Benioff Children Hospital in San Francisco. “The importance of having a non-pharmacologic, discrete, easy-to-use and effective acute treatment in the adolescent armamentarium cannot be overstated.”

Long-Term Effects of Childhood Migraine

Early treatment of childhood migraine is important because there is emerging evidence that repeated headache attacks in children reduce the formation of “gray matter” in parts of the brain that process pain signals, leading to more frequent and severe migraines in adults.   

“We’ve done studies here independent of any pharmaceutical company where we’ve show that the earlier we can intervene with effective therapy and education of patients, the better their long-term outcome,” Hershey told PNN. “So we really have this opportunity to intervene with a child or adolescent that can affect them for their life.

“A device can be as effective as a drug. What I tell patients is that it gives them their own locus of control. Instead of taking a medication and hoping it works, they’re actually controlling the device with their smartphone, and so they can really take control of their headaches, which is ultimately what we want them to do.”    

Nerivio is only available by prescription and is eligible for insurance. When purchased wholesale, the listed price is $599 for a twelve-treatment unit, although buyers can save money by enrolling in a patient savings program, depending on their insurance coverage.  

Theranica is currently recruiting patients for a placebo-controlled study to see if Nerivio may be effective in preventing migraines. The company is also investigating whether the device may help treat other chronic pain conditions besides migraine.

Migraine affects more than 37 million people in the United States, according to the American Migraine Foundation. In addition to headache pain, migraine can cause nausea, blurriness or visual disturbances, and sensitivity to light and sound. Women are three times more likely to suffer from migraines than men.
