VALUE Study Seeks Patient Perspective on Long-Term Opioid Use

By Pat Anson, PNN Editor

In 2011, the Institute of Medicine released its landmark report, “Relieving Pain in America,” an ambitious project aimed at improving pain care, education and research in United States.

One of the report’s co-authors was Stanford University’s Dr. Sean Mackey, who remembers telling colleagues at the time that more research was needed on the long-term use of opioid pain relievers.     

“One of the questions I put forward to the group was, ‘One of the biggest questions that we need to answer is do opioids help relieve chronic pain for some people?’ Do they actually work? And if so, for whom do they work?” Mackey recalls.

“And surprisingly, ten years later, here we are in 2021 and I would submit to you that we still don’t know the answer to that question. We still do not know how well long-term prescribing of opioids work for chronic pain and for which person they work for. We understand much better who they don’t work for. But we don’t know the flip side.”

Mackey is now leading a study aimed at finally answering the question. The VALUE study is designed to give patients a voice in determining whether opioids can be a safe, effective and long-term treatment for chronic pain.

Mackey and co-investigator Beth Darnall, PhD, along with a team of patient advocates, hope to get up to 500 chronic pain sufferers to enroll in their year-long study. Patients will be asked to participate in three online surveys and three phone calls, answering questions about their pain, symptoms, mood, sleep, quality of life, and whether they encountered any problems or stigma from using opioids.

Long-Term Studies Lacking

Many doctors, regulators and opioid critics claim – disingenuously – that there is no evidence supporting the long-term use of opioids. But the truth is the same could be said for all pain relievers, including non-opioids. Few placebo-controlled studies have been conducted on the long-term use of any pain medication -- simply because it would be unethical to subject a participant to untreated pain for a lengthy period.

That leaves it to patients to share their own experiences with opioids, and a shrinking pool of doctors like Mackey who are not afraid to prescribe them.

“In my caring for people who suffer from pain and for whom it takes a big toll, I have clearly seen a subset of people for whom they do work,” Mackey told PNN. “What we’re trying to do here is transcend what has become a one-size-fits-all approach to patient treatment and the issue of opioids. We’ve become rather guideline-based and we treat all people as if they were an average in a clinical trial. I don’t treat averages. I treat people.

“Everybody is unique and deserves to be treated as an individual. That doesn’t mean that we can’t be guided by those research studies and averages, but we need to get at a more personalized approach. We need to recognize, at least in many of our experiences, there are sub-groups of people who respond to opioids. The problem is we don’t have good data on who they are.”

People who volunteer for the VALUE study should be prepared to spend a fair amount of time answering questions. Each survey will take about 45 minutes to complete. Participants will complete the first survey when they enroll, the second one after 6 months, and the third survey after one year. For each completed survey, patients will be compensated with an Amazon or gift card.

All information collected will be confidential, and won’t be shared with doctors, regulators or insurers. Participants can even use a pseudonym if they don’t feel comfortable using their real names. The VALUE study website has a list of other frequently asked questions.

People interested in participating should contact study coordinator Hannah Cunningham by email at hcunning@stanford.edu or by calling 1-833-668-0277.

“We believe our findings will have broad policy indications at local, state and national levels that will hopefully make opioid prescribing guidelines more patient centered, more effective and safer,” says Mackey.

Study Finds Placebos Disrupt Pain Signals in Brain

By Pat Anson, PNN Editor

Much of the pain relief that a person gets from taking an analgesic medication is due to individual mindset, not the drug itself, according to new research that looks at how the human brain responds to a placebo.

The placebo effect is a well-documented but poorly understood condition in which a patient responds to a drug or treatment that is designed to have no therapeutic value. A 2018 study, for example, found that about half of patients who took a sugar pill they thought was an analgesic had a 30% reduction in pain – a level considered effective for an actual painkiller.    

To better understand how that is possible, researchers at Dartmouth University conducted a meta-analysis of 20 neuroimaging studies involving 603 healthy people who participated in placebo studies. Their findings, recently published in Nature Communications, showed that placebo treatments reduced pain-related activity in multiple areas of the brain.

"Our findings demonstrate that the participants who showed the most pain reduction with the placebo also showed the largest reductions in brain areas associated with pain construction," explains co-author Tor Wager, PhD, a Neuroscience Professor who is principal investigator of the Cognitive and Affective Neuroscience Lab at Dartmouth.

"We are still learning how the brain constructs pain experiences, but we know it's a mix of brain areas that process input from the body and those involved in motivation and decision-making. Placebo treatment reduced activity in areas involved in early pain signaling from the body, as well as motivational circuits not tied specifically to pain."

By examining brain images, researchers were able to identify the placebo effect in regions of the brain that process pain signals (nociception) and generate pain sensations.

They found that placebos strongly affect the thalamus, which processes sights, sounds and other types of sensory input; as well as the basal ganglia, which is important for motivation and pain-related activities.

Placebo treatments also reduced activity in the brain’s posterior insula, which is one of the areas involved in creating pain sensations. This suggests that placebos change the pathway for how pain is processed in the brain. 

"The placebo can affect what you do with the pain and how it motivates you, which could be a larger part of what's happening here," says Wager. "It's changing the circuitry that's important for motivation."

Previous research has found that placebos activate the brain’s prefrontal cortex, which triggers the release of natural, pain-relieving hormones that can block pain signals from being processed.

Researchers say placebo effects likely involve a combination of different brain reactions, depending on the placebo and people's predispositions. In other words, there is no uniformity in the placebo response because everyone is different.

"Our results suggest that placebo effects are not restricted solely to either sensory/nociceptive or cognitive/affective processes, but likely involves a combination of mechanisms that may differ depending on the placebo paradigm and other individual factors," said co-author Ulrike Bingel, PhD, a professor at the Center for Translational Neuro- and Behavioral Sciences at University Hospital Essen.

A 2016 study that looked at brain images of osteoarthritis patients found that about half had mid-frontal brain regions that had more connectivity with other parts of the brain, making them more likely to respond to the placebo effect. That could help could explain why some respond well to pain medication, while others do not.

How Long Haul Covid Alters the Immune System

By Liz Szabo, Kaiser Health News

There’s a reason soldiers go through basic training before heading into combat: Without careful instruction, green recruits armed with powerful weapons could be as dangerous to one another as to the enemy.

The immune system works much the same way. Immune cells, which protect the body from infections, need to be “educated” to recognize bad guys — and to hold their fire around civilians.

In some Covid-19 patients, this education may be cut short. Scientists say unprepared immune cells appear to be responding to the coronavirus with a devastating release of chemicals, inflicting damage that may endure long after the threat has been eliminated.

“If you have a brand-new virus and the virus is winning, the immune system may go into an ‘all hands on deck’ response,” said Dr. Nina Luning Prak, co-author of a January study on Covid and the immune system. “Things that are normally kept in close check are relaxed. The body may say, ‘Who cares? Give me all you’ve got.’”

While all viruses find ways to evade the body’s defenses, a growing field of research suggests that the coronavirus unhinges the immune system more profoundly than previously realized.

Some Covid survivors have developed serious autoimmune diseases, which occur when an overactive immune system attacks the patient, rather than the virus. Doctors in Italy first noticed a pattern in March 2020, when several Covid patients developed Guillain-Barré syndrome, in which the immune systems attacks nerves throughout the body, causing muscle weakness or paralysis.

As the pandemic has surged around the world, doctors have diagnosed patients with rare, immune-related bleeding disorders. Other patients have developed the opposite problem, suffering blood clots that can lead to stroke.

All these conditions can be triggered by “autoantibodies” — rogue antibodies that target the patient’s own proteins and cells. In a report published in October, researchers even labeled the coronavirus “the autoimmune virus.”

Although doctors are researching ways to overcome immune disorders in Covid patients, new treatments will take time to develop. Scientists are still trying to understand why some immune cells become hyperactive — and why some refuse to stand down when the battle is over.

Key immune players called “helper T cells” typically help antibodies mature. If the body is invaded by a pathogen, however, these T cells can switch jobs to hunt down viruses, acting more like “killer T cells,” which destroy infected cells. When an infection is over, helper T cells usually go back to their old jobs.

In some people with severe Covid, however, helper T cells don’t stand down when the infection is over, said James Heath, a professor and president of Seattle’s Institute for Systems Biology.

About 10% to 15% of hospitalized Covid patients Heath studied had high levels of these helper T cells, which were still looking for the enemy long after it had been eliminated. He’s now studying whether these overzealous T cells might inflict damage that leads to chronic illness or symptoms of autoimmune disease.

“These T cells are still there months later and they’re aggressive,” Heath said. “They’re on the hunt.”

Friendly Fire

Covid appears to confuse multiple parts of the immune system. In some patients, Covid triggers autoantibodies that target the immune system itself, leaving patients without a key defense against the coronavirus.

In October, a study published in Science led by Rockefeller University’s Jean-Laurent Casanova showed that about 10% of Covid patients become severely ill because they have antibodies against an immune system protein called interferon.

Disabling interferon is like knocking down a castle’s gate. Without these essential proteins, invading viruses can overwhelm the body and multiply wildly.

New research shows that the coronavirus may activate preexisting autoantibodies, as well as prompt the body to make new ones. In the January study, half of the hospitalized Covid patients had autoantibodies, compared with fewer than 15% of healthy people.

Other research has produced similar findings. In a study out in December, researchers found that hospitalized Covid patients harbored a diverse array of autoantibodies.

While some patients studied had antibodies against virus-fighting interferons, others had antibodies that targeted the brain, thyroid, blood vessels, central nervous system, platelets, kidneys, heart and liver, said Dr. Aaron Ring, assistant professor of immunology at Yale School of Medicine.

Similarities With Lupus

Some patients had antibodies associated with lupus, a chronic autoimmune disorder that can cause pain and inflammation in any part of the body. Covid patients rife with autoantibodies tended to have the severest disease, said Ring, who was surprised at the level of autoantibodies in some patients.

“They were comparable or even worse than lupus,” Ring said.

Researchers would like to know if lingering autoantibodies contribute to the symptoms of “long Covid,” which afflicts one-third of covid survivors up to nine months after infection, according to a new study in JAMA Network Open.

“Long haulers” suffer from a wide range of symptoms, including debilitating fatigue, shortness of breath, cough, chest pain and joint pain. Other patients experience depression, muscle pain, headaches, intermittent fevers, heart palpitations and problems with concentration and memory, known as brain fog.

Less commonly, some patients develop an inflammation of the heart muscle, abnormalities in their lung function, kidney issues, rashes, hair loss, smell and taste problems, sleep issues and anxiety.

The National Institutes of Health has announced a four-year initiative to better understand long Covid, using $1.15 billion allocated by Congress.

Ring said he’d like to study patients over time to see if specific symptoms might be explained by lingering autoantibodies.

“We need to look at the same patients a half-year later and see which antibodies they do or don’t have,” he said. If autoantibodies are to blame for long Covid, they could “represent an unfortunate legacy after the virus is gone.”

Is Recreational Drug Use a Human Right?

By Roger Chriss, PNN Columnist

The book “Drug Use for Grown-Ups” by Carl Hart, PhD, is garnering a lot of attention. Hart argues that recreational drug use is a fundamental human right, while also describing the harms of drug laws and policy on people of color. His book is a mixture of anecdote and analysis that raises a lot of important issues about drugs and society.

Hart is unapologetic about his own drug use and that of others, saying that "Adults should be permitted the legal right to sell, purchase, and use recreational drugs of their choice." He sees drug use as “beneficial for human health and functioning” and causing ‘little or no harm” in most instances.

Specifically, Hart states that drug use is an "act that the government is obliged to safeguard” because it is a part of the “pursuit of happiness” in the Declaration of Independence. He claims that Thomas Jefferson, one of the authors of the Declaration, was “a long-term avid drug user.”

Hart, who is a psychology professor at Columbia University, raises numerous questions in a blunt and sometimes brusque fashion, asking “Why is it that guns can be legally purchased but heroin cannot?”

He challenges his readers with remarks like: “Few would balk at using Viagra or Cialis to enhance sexual performance, but many more find it objectionable to use drugs such as amphetamines to improve the sexual experience.”

Hart doesn't mythologize or romanticize drugs or their users, and questions why advocates of the psychedelic movement call themselves “psychonauts.”

“The term psychonaut in itself is another attempt to dissociate middle-class psychedelic users from users of drugs such as crack and heroin, who are disapprovingly called ‘crackheads’ or ‘dope fiends’.”

Hart defends this position by pointing out that nearly 80 percent of illicit drug users don’t have problems such as addiction. He explains that his own heroin use is rational: “Like vacation, sex, and the arts, heroin is one of the tools that I use to maintain my work-life balance.”

As for overdose deaths, Hart contends that contaminated drugs are the issue. “A regulated market, with uniform quality standards, would virtually put an end to contaminated drug consumption and greatly reduce fatal, accidental overdoses,” he writes.

Further, Hart states that drug addiction is not a brain disease, writing that there is no evidence indicating that “responsible recreational drug use” causes brain abnormalities. He says obsessing over addiction has caused harm by stigmatizing drug users as unworthy of social support or rehabilitative care. Hart sees the opioid crisis as overblown and rooted in racism.

“All the evidence from research clearly shows that most heroin users are people who use the drug without problems, such as addiction; they are conscientious and upstanding citizens,” he writes. “The new ‘get tough on opioids’ policies have been fueled by the mistaken perception that most illegal opioid dealers are black or Latino.”

Legalization, Hart claims, is the key to changing all this. Prohibition of alcohol gave birth to criminal gangs and a thriving underground market in booze, some of it so contaminated with impurities it made people sick or even killed them. “This problem went away when Prohibition was repealed,” he points out.

But not all of this holds up so well. Hart argues that a legalized market with regulated substances would keep people safe, but he himself chooses to use an illicit substance called “hex” of unknown provenance and effect while at a drug festival.

“I now include hex among the drugs I might want to take immediately before attending some awful required social event, such as an academic reception or an annual departmental holiday party,” he wrote.

Hart’s book is also notable for what it lacks. He doesn’t look at public health data or long-term studies on drug risks and user outcomes in the U.S. or other countries, and ignores animal research on drug risks and harms.

Hart also omits recent discouraging research on drug legalization and social justice. According to the University of Washington’s Alcohol & Drug Abuse Institute, legalization of cannabis has had no impact on reducing racial bias in policing and other disparities in the criminal justice system.   

He also doesn’t discuss the under-treatment of pain in people of color due to myths about higher pain tolerance, lack of nerve endings, or greater abuse and addiction risk.

Hart clearly shows the harms of current drug policy, but arguably overstates the potential benefits of legalization. And his blunt style sometimes diminishes his own credibility.  Overall, the book “Drug Use for Grown-Ups” adds to the discussion of drug policy in the U.S. by asking some challenging questions, but doesn’t resolve many important issues.

It’s Time for People in Pain To Be Heard

By Carol Levy, PNN Columnist

I just had my second “there's an issue with filling your codeine prescription” incident.

I have been on codeine, on and off, for over 30 years. Initially, I was allowed refills. When that was no longer permitted, my doctor gave me a new prescription, each and every month, for 120 pills.

When my trigeminal neuralgia pain became somewhat better as a result of various surgeries, I often took only 1 or 2 pills per day.

I am now about 90% housebound. Part of it is due to Covid, but mostly it’s because I do not want to go out and make the baseline pain worse. As a result, some days I take no codeine at all. My last prescription was for 120 pills. It was a month’s supply that lasted for 9 months.

The first incident was last year, when my pain management doctor decided, without discussing it with me, that he was no longer writing scripts for 120 codeine pills a month. Instead, he changed it to 10 pills a month.

I was told he didn’t like me having extra pills, a nonsensical excuse as I had no history of giving them away or taking too many. Prescriptions for 120 pills just made it easier for everyone, including the insurance company, since they would be paying less for fewer doctor appointments.

Fortunately, I was able to go to my family doctor, who had no problem writing for 120 pills. They trusted me there, knowing I would not abuse them.

But when I took the script to the pharmacy, I was told, “We can only fill a 7-day supply per your insurance company.”

The worst part about that was not that I would have to repeatedly go back to the pharmacy, but that the cost for each 7-day supply was much more for me out-of-pocket than if they just filled the whole prescription at once.

My Physician Assistant called the insurance company to ask for a pre-authorization. This would allow the pharmacy to fill the entire amount at one time. They immediately allowed it for the next 12 months, which seemed odd.

If they think I should only be getting a 7-day supply, then why allow the whole script to be filled for an entire year? Either I am untrustworthy or I'm not.

I am lucky. I don’t rely on daily opioids to get me out of bed, go to the store or be able to work. So many of us have no other option but to take them. My annoyance is tame compared to what other patients go through, who have been unable to get what they need due to restrictions on prescribing.

Physicians for Responsible Opioid Prescribing (PROP) recently sent a letter to the AMA saying the organization shouldn’t be calling for changes in the CDC opioid guideline, even though far more people are dying from street drugs than prescription opioids.

“Medically prescribed opioids remain a common gateway to illicit opioid use and are themselves frequent causes of opioid addiction and overdose, even if illicit opioids currently cause the greater number of deaths,” PROP said.

PROP founder Dr. Andrew Kolodny even said that prescriptions “still have a very long way to go” and should be reduced even further.

PROP’s reach is loud and strong. We complain so much to each other, patient support groups, Twitter and other social media about how awful this is, how unfair and inhumane.

A number of people have started online petitions to send to the FDA or CDC, asking that the guidelines be changed so they stop hurting chronic pain patients. Many say, “This is a great idea.” Yet few actually sign.

Nothing will change if we don’t band together and make our voices heard. The call keeps going out, “Something must be done!” But too often the answer is, “Oh yes, somebody must do something. But I'm too busy.”

Whispering in the wind won’t help. It is long past time for us to become a true force, with a voice that is louder and stronger than PROP’s.

New European Guideline Says Opioids ‘Do Not Work’ for Many Types of Chronic Pain

By Pat Anson, PNN Editor

Calling opioid medication a “two edged sword,” the European Pain Federation (EFIC) has released new guidelines that strongly recommend against using opioids to treat fibromyalgia, low back pain, migraine, irritable bowel syndrome and other types of chronic non-cancer pain.

“The new recommendations advise that opioids should not be prescribed for people with chronic primary pain as they do not work for these patients,” the EFIC said in a statement.

However, the guideline states that low doses of opioids may be suitable for treating “secondary pain syndromes” caused by surgery, trauma, disease or nerve damage, but only after exercise, meditation and other non-pharmacological therapies are tried first.

“Opioids should neither be embraced as a cure‐all nor shunned as universally dangerous and inappropriate for chronic noncancer pain. They should only be used for some selected chronic noncancer pain syndromes if established non‐pharmacological and pharmacological treatment options have failed,” the guideline states. “In this context alone, opioid therapy can be a useful tool in achieving and maintaining an optimal level of pain control in some patients.”

Opioid pain relievers are not as widely used in Europe as they are in the United States or Canada. The EFIC said it was trying to “allay concerns over an opioid crisis” developing in Europe, as it has in North America.       

“As the leading pain science organisation in Europe, it is crucial that EFIC sets the agenda on issues such as opioids, where there are growing societal concerns. These recommendations clarify what role opioids should play in chronic pain management,” EFIC President Brona Fullen said in a statement.

The guideline’s lead author, Professor Winfried Häuser, said he and his colleagues tried to strike a middle ground on the use of opioids.

“The debate on opioid-prescribing for chronic non-cancer pain has become polarized: opioids are either seen as a dangerous risk for all patients, leading to addiction and deaths, or they are promoted as most potent pain killers for any type of pain,” said Häuser, who is an internal medicine specialist in Germany.

“Opioids are still important in the management of chronic non-cancer pain – but only in some selected chronic pain syndromes and only if established non-pharmacological and non-opioids analgesics have failed or are not tolerated.”

PROP Consulted for European Guideline

The guideline was developed by a 17-member task force composed of European experts in pain management, including 9 delegates selected by EFIC’s board “who advocate and who are critical with the use of opioids.” Only one delegate from Pain Alliance Europe represented patients.

The recommendations developed by the task force were reviewed by five outside experts, including Drs. Jane Ballantyne and Mark Sullivan, who belong to Physicians for Responsible Opioid Prescribing (PROP), an anti-opioid activist group in the U.S.  Ballantyne is PROP’s President, while Sullivan is a PROP board member. Several changes suggested by the outside experts were adopted.

Coincidentally, Ballantyne, Sullivan and three other PROP board members were involved in the drafting of the opioid guideline released in 2016 by the U.S. Centers for Disease Control and Prevention. That controversial guideline is now being rewritten by the CDC after voluminous complaints from patients and doctors that the recommendations led to forced tapering, withdrawal, uncontrolled pain and suicides.

Sullivan and two other PROP board members were also involved in drafting Canada’s 2017 opioid guideline, which was modeled after the CDC’s and provoked similar complaints from Canadian pain patients.

90 MME Recommended Limit

The CDC and Canadian opioid guidelines appear to have been used as resources by the EFIC task force, which adopted many of the same recommendations, even while acknowledging the low quality of evidence used to support them.   

One recommendation is straight out of the CDC guideline, advising European doctors to “start low and go slow.” Prescribers are urged to start patients on low doses of 50 morphine milligram equivalents (MME) or less a day and to avoid increasing the dosage above 90 MME/day.

One significant difference with the North American guidelines is that the EFIC recommends that opioids not be prescribed for fibromyalgia, migraines and other chronic “primary pain” conditions for which there is no known cause – suggesting those disorders have an emotional or psychological element that will lead to opioid abuse.

“Prescription of high doses of opioids to patients with primary pain syndromes might have been a factor driving the opioid crisis in North America,” the EFIC guideline warns.

“This was further compounded by patient characteristics that included physical and psychological trauma, social disadvantage and hopelessness that served as a trigger for reports of pain intensity prompting prescriptions of more opioids.”

Secondary pain conditions for which opioids “can be considered“ include multiple sclerosis, stroke, restless leg syndrome, Parkinson’s disease, rheumatoid arthritis, phantom limb pain, non-diabetic neuropathy, spinal cord injuries and Complex Regional Pain Syndrome (CRPS). 

Unlike the North American guidelines, the EFIC acknowledges that there are physical and genetic differences between patients. Some patients who are rapid metabolizers “might require higher dosages of opioids than the ones recommended by the guidelines.“

EFIC GRAPHIC

The EFIC also warns that its guideline should not be used to justify abruptly tapering or discontinuing opioids for anyone already prescribed at higher dosages. The recommendations are also not intended for the management of short-term acute pain, sickle cell disease or end-of-life care.

Individualized Pain Care After Surgery Raises Patient Satisfaction

By Pat Anson, PNN Editor

An opioid prescribing guideline tailored to a patient’s specific needs – that doesn’t take a one-size-fits-all approach – resulted in high patient satisfaction rates and reduced the use of opioids after surgery.

The post-operative pain management guideline was developed by surgeons at Dartmouth-Hitchcock Medical Center in New Hampshire, who based the number of opioid pills sent home with patients on how many they needed the day before they were discharged from the hospital. Other guidelines typically base the number of pills on the type of operation that was performed and do not take into account a patient’s individual needs.

“In this new prospective study we found that 93 percent of patients had their post-surgery opioid needs satisfied,” said lead author Richard Barth Jr., MD, section chief of general surgery. “This finding means that this guideline can be used for a wide variety of operations to guide surgeons on how many opioids to prescribe when sending patients home after surgery.”

Barth and his colleagues enrolled 229 patients in the study who had elective general surgery, including colorectal, gynecological, thoracic and urological operations. Upon discharge, patients received prescriptions for acetaminophen and ibuprofen, as well as opioids, based on the guideline.

If they needed no opioids the day before discharge, they were sent home with the morphine milligram equivalent (MME) of five oxycodone 5mg pills. If they took one or three pills, they were given a prescription for 15 more. And if they needed four or more pills, they were given a prescription for 30 pills.  

Patient satisfaction was highest among those who needed the fewest number of pills. Despite being given an opioid prescription, 73 percent of the patients who were prescribed five pills used no opioids at home, and 85 percent used two pills or less.

In all, 60 percent of patients in the study had leftover opioid pills, according to findings published in the Journal of the American College of Surgeons. They were given instruction on how to dispose of them safely.

Barth says surgeons played a pivotal role in minimizing opioid use by talking to patients before surgery and setting their expectations for pain management. They told patients they were likely to be discharged with either no opioids or a small amount based on their opioid use in the hospital.

“The other part of that discussion involves letting patients know that they should expect some pain, that our goal isn’t to get rid of every last bit of their pain,” Barth said. “That was something that surgeons tried to accomplish years ago, but that’s not what we’re aiming for now. A low level of discomfort is acceptable, and patients need to have that expectation.”

That process also including prescribing, not just recommending, over-the-counter pain relievers.  

“By prescribing non-opioid analgesics, the surgeon sets the expectation that they should be used,” he said. “It’s a big difference if a surgeon prescribes non-opioid analgesics compared with just recommending that a patient take acetaminophen or ibuprofen that they might have at home.” 

In recent years, many U.S. hospitals have adopted policies that reduce or completely eliminate the use of opioids after surgery. Those policies unfairly leave some patients in pain, according to a recent study presented at the annual meeting of the American College of Surgeons. Researchers found that about half of patients need opioid medication after major surgeries.

“Our goal is to give them the exact right amount so that we limit the number of un-used opioids in our community while also making sure we don’t reduce it down too far and then leave them in pain,” said lead author Cornelius Thiels, DO, a surgical oncology fellow at Memorial Sloan Kettering Cancer Center.

“The right answer may be more non-opioid based pain medications, better patient education and setting of expectations, or in some cases patients may actually require slightly more opioid medications, and that is OK.”

Medical Cannabis Linked to Rebound Headaches

By Pat Anson, PNN Editor

Medication overuse headache, also known as “rebound” headache, is a common problem for people who frequently use pain medication to relieve headaches and migraine.

According to the American Migraine Foundation, rebound headaches can be triggered by a wide assortment of analgesics, from aspirin and triptans to acetaminophen and opioids. Even caffeine can cause a rebound headache if you consume more than 200mg a day – about two cups of coffee.     

So perhaps it’s not surprising that medical cannabis is also associated with medication overuse headache, according to a preliminary study by researchers at Stanford University School of Medicine.

“Many people with chronic migraine are already self-medicating with cannabis, and there is some evidence that cannabis can help treat other types of chronic pain,” said study author Niushen Zhang, MD, a neurologist who is director of Stanford’s Headache Fellowship Program.

“However, we found that people who were using cannabis had significantly increased odds of also having medication overuse headache, or rebound headache, compared to people who were not using cannabis.”

Zhang and her colleagues looked at the medical records of 368 people who had chronic migraine -- which is 15 or more headache days per month. Less than half were using medical cannabis

Researchers found the cannabis users were six times more likely to have rebound headaches than those who did not use cannabis. People who used cannabis were also more likely to take opioids.  Previous research has found that opioids and cannabis can both influence the part of the brain called the periaqueductal gray, which has been linked to migraine.

Zhang’s study will be presented at the American Academy of Neurology’s annual meeting next month.

Medical cannabis has become a trendy alternative to pharmaceuticals for treating migraine, with research showing that both inhaled and ingested cannabis can reduce migraine pain. 

A recent study of nearly 10,000 people in the U.S. and Canada who used a migraine tracking app found that 82 percent who used cannabis believed it was an effective pain reliever.    

A 2017 study conducted in Israel found that combining THC and CBD in an oral dose was just as effective in treating migraine pain as amitriptyline – a tricyclic antidepressant commonly prescribed for migraine.

And a 2016 study at the University of Colorado found that cannabis significantly reduced the number of migraine headaches. Inhalation appeared to provide the fastest results, while edible cannabis took longer to provide pain relief.

About a billion people worldwide suffer from migraine headaches, which affect three times as many women as men. Over 37 million people in the United States live with migraines, according to the American Migraine Foundation.

Don't Get Picky: All Three Covid Vaccines Highly Effective

By Arthur Allen and Liz Szabo, Kaiser Health News

When getting vaccinated against Covid-19, there’s no sense being picky. You should take the first authorized vaccine that’s offered, experts say.

The newest Covid vaccine on the horizon, from Johnson & Johnson, is probably a little less effective at preventing sickness than the two shots already being administered around the U.S., from Pfizer-BioNTech and Moderna.

The Food and Drug Administration authorized the Johnson & Johnson vaccine after reporting it showed about 66% effectiveness at preventing Covid illness in a 45,000-person trial. No one who received the vaccine was hospitalized with or died of the disease, according to the data released by the company and FDA. As many as 4 million doses could be shipped out of J&J’s warehouses beginning this week.

The J&J vaccine is similar to the shots from Moderna and Pfizer-BioNTech, but uses a different strategy for transporting genetic code into human cells to stimulate immunity to the disease. The Moderna and Pfizer-BioNTech vaccines were found in trials last fall to be 94% effective in preventing illness caused by Covid. They also prevented nearly all severe cases.

But the difference in those efficacy numbers may be deceptive. The vaccines were tested in different locations and at different phases of the pandemic. And J&J gave subjects in its trial only one dose of the vaccine, while Moderna and Pfizer have two-dose schedules, separated by 28 and 21 days, respectively. The bottom line, however, is that all three do a good job at preventing serious Covid.

“It’s a bit like, do you want a Lamborghini or a Chevy to get to work?” said Dr. Gregory Poland, director of the Mayo Clinic’s Vaccine Research Group, who was a paid consultant in the J&J study. “Ultimately, I just need to get to work. If a Chevy is available, sign me up.”

“From a personal and public health perspective, the best advice for now is to get whatever you can as soon as you can get it, because the sooner we all get vaccinated the better off we all are,” said Dr. Norman Hearst, a family doctor and epidemiologist at the University of California-San Francisco.

Of the 10 people who got severe disease in the Pfizer trial, nine had received a placebo, or fake vaccine; none of the 30 severe cases in the Moderna trial occurred in people who got the true vaccine. A month after receiving the Johnson & Johnson shot there were no deaths or hospitalizations in those who had been vaccinated.

“The real goal is to keep people out of the hospital and the ICU and the morgue,” said Dr. Paul Offit, director of the Vaccine Education Center at Children’s Hospital of Philadelphia. “This vaccine will do that well.”

J&J Vaccine Tested Against Variants

The data that Moderna and Pfizer-BioNTech presented to the FDA for their vaccines came from large clinical trials that took place over the summer and early fall in the United States. At the time, none of the new variants of Covid — some of which may be better at evading the immune responses produced by vaccines — were circulating here.

In contrast, the J&J trial began in September and was put into the arms of people in South America, South Africa and the United States. The J&J vaccine was 72% effective against moderate to severe Covid in the U.S. part of the trial, compared with 57% in South Africa, where a more contagious mutant virus is the dominant strain.

The Moderna and Pfizer-BioNTech vaccines might not have gotten the same sparkling results had they been tested more recently — or in South Africa.

“This vaccine was tested in the pandemic here and now,” said Dr. Dan Barouch, a Harvard Medical School professor whose lab at the Center for Virology and Vaccine Research at Beth Israel Deaconess Medical Center in Boston developed the J&J vaccine. “The pandemic is a much more complex pandemic than it was several months ago.”

The J&J vaccine appears to have some other advantages. First, it seems to cause fewer serious side effects like the fever and malaise suffered by some Pfizer-BioNTech and Moderna vaccine recipients. High fever and dehydration are particular concerns in fragile elderly people who “have one foot on the banana peel,” said Dr. Kathryn Edwards, scientific director of the Vanderbilt Vaccine Research Program. The J&J vaccine “may be a better vaccine for the infirm.”

Many people may prefer the J&J shot because “it’s one and done.” It’s easier for administrators too: just one appointment to schedule.

The J&J vaccine can also be stored in regular refrigerators, while the Pfizer and Moderna vaccines have to be stored in freezers and must be used or discarded within six hours after the vial is opened. Vials of the J&J vaccine can be restored in a refrigerator for later use if doses remain.

“Right now we have mass immunization clinics that are open but have no vaccine,” said Offit. “Here you have a single-dose regime with easy storage and handling.”

Ultimately, a person’s address — not their personal preference — may determine which vaccine they receive, said E. John Wherry, director of the Institute for Immunology at the University of Pennsylvania’s Perelman School of Medicine. He pointed out that the Johnson & Johnson vaccine is a simpler choice for rural areas.

“A vaccine doesn’t have to be 95% effective to be an incredible leap forward,” said Wherry. “When we get to the point where we have choices about which vaccine to give, it will be a luxury to have to struggle with that question.”

What COVID-19 Teaches Us About Rare Diseases

By Roger Chriss, PNN Columnist

Sunday, February 28th is Rare Disease Day -- a day created to recognize and increase awareness of rare diseases that affect millions of people worldwide. This year that includes the effects of Covid-19 on the rare disease community.

The National Organization of Rare Disorders reports that there are over 7,000 rare diseases. A disease is considered rare in the U.S. if it affects fewer than 200,000 people; while in Europe a disease is classified as rare if it affects fewer than 1 in 2,000 people. Although each disease is rare, there are so many conditions that roughly 1 in 17 people are affected by a rare disease.

Rare Disease Day 2021 is occurring amid a pandemic. Covid-19 has increased awareness of medical problems like anosmia, a loss of sense of smell. In it congenital form, anosmia affects only 1 in 10,000 people, but now it is seen in millions infected with the coronavirus. For most, the loss of smell is temporary, but for some Covid patients it persists long after the initial infection.

“One might think that it is not important to be able to smell nature, trees, forests,” Evan Cesa told AP News. “But when you lose the sense of smell, you realize how truly lucky we are to be able to smell these things.”

Long Haul Covid

In a recent study, University of Washington researchers monitored 300 recovering Covid patients in the Seattle area and found that 30% reported worse health and quality of life in the wake of the illness. Some were unable to perform simple chores, lift heavy objects or walk for more than a short distance.

Chronic Covid syndrome (CSS), also known as long-haul Covid, seems to occur in about 10% of infected people. In addition to loss of smell, long haulers often have disabling fatigue, headache, shortness of breath, weakness and brain fog – symptoms that are strikingly similar to chronic fatigue syndrome (CFS/ME).

Research on how to manage long-haul Covid is looking at treatments already used for rare disorders. A clinical trial of low-dose naltrexone (LDN) is underway. LDN is sometimes used to treat refractory chronic pain conditions, and is being explored for lupus and obsessive-compulsive disorder.

The pandemic has created new challenges for the rare disease community. Accessing medical care amid a pandemic has been tricky, in particular for people whose immune function is compromised. And the handful of deaths associated with Covid vaccines has raised questions for people with severe thrombocytopenia (ITP), a rare platelet disorder.

Covid-19 is revealing what living with a rare disease is like. Some people with long-haul Covid are reluctant to disclose their condition, much as people with rare disorders often struggle with when and how to share information about their diagnoses.  

People with long haul Covid are struggling to gain recognition for their disability. As NPR reports, long haulers have asked the federal government for disability coverage, rights and protections -- but it's unclear if they qualify under the Americans with Disability Act.

While Covid-19 has increased awareness of rare diseases, it’s also slowing rare disease research and complicating care. This year, many Rare Disease Day events are being held online due to the pandemic.

Hopefully, Rare Disease Day in 2022 will take place in a post-Covid world.

Who Develops Intractable Pain Syndrome?

By Forest Tennant, PNN Columnist

It is clear that a small percentage of chronic pain patients can develop Intractable Pain Syndrome (IPS), which is constant, incurable pain that has cardiovascular and endocrine complications. But which unfortunate chronic pain patients will succumb to this fate?

To this end, we have been surveying persons with IPS to understand who they are and how they developed the syndrome. Without knowledge as to “who” and “how” IPS occurs, it will be impossible to either prevent the condition, identify it in early stages or stop its progression.

In a survey of persons with IPS, we found that many were older and primarily female. Out of 28 patients surveyed, 20 were female and 8 were male, and their ages ranged from 34 to 77 years. The average age was 56 years.

In addition, these individuals had been ill and experienced chronic pain for many years. Only two of the 28 patients surveyed reported pain of less than five years duration. The majority could actually recall the day, month and year that their chronic pain shifted to IPS. 

Almost all reported three major manifestations:

• 100% Physical function declined

• 86% Needed medication to sleep

• 82% Mental functions declined

Key laboratory tests were frequently abnormal:

• 71% Hormone abnormality

• 53% High inflammatory markers 

• 32% High glucose levels 

The 28 patients surveyed were asked what medical conditions caused their IPS. Surprisingly, the majority said they had multiple diagnoses, which are listed below by condition:

• 20 Adhesive Arachnoiditis

• 9 Ehlers-Danlos Syndrome

• 7 Cervical Neck Neuropathy

• 5 Osteoarthritis

• 2 Reflex Sympathetic Dystrophy (CRPS)

• 2 Interstitial Cystitis

• 2 Traumatic Brain Injury

• 1 Rheumatoid Arthritis

• 1 Stroke

These findings show that IPS can develop from a relatively small number of painful conditions, with Adhesive Arachnoiditis and Ehlers-Danlos Syndrome the most common ones reported. Persons with IPS almost all report severe insomnia and declines in their physical and mental abilities. And laboratory tests validate the abnormal physiological impact of their non-stop constant pain.

In a separate clinical analysis of 40 persons with IPS, we found that over 60% had symptomatic characteristics in common, from constant pain and difficulty sleeping to sugar cravings and cold hands and feet. For a list of over two dozen IPS symptoms, click here.

Our mission forward as the IPS Research and Education Project is to bring recognition and treatment of IPS to every community across the globe. This presents a great challenge for us; to instruct and inform all concerned parties in acknowledging that IPS is a serious syndrome, and that it is exceedingly different from what is commonly known as chronic pain.

Abuse of Rx Opioid Painkillers Unchanged During Pandemic

By Pat Anson, PNN Editor

An alarming spike in U.S. overdose deaths during the COVID-19 pandemic does not appear to be fueled by increased abuse of opioid painkillers, according to a new nationwide analysis of urine drug tests.

The Drug Enforcement Administration approved an exemption last year allowing patients to connect with doctors via telehealth – without a physical examination -- to get prescriptions for opioids and other controlled substances. While the relaxed rules made it easier for patients to get pain medication during the pandemic, they have not resulted in more diversion or abuse of oxycodone and hydrocodone, according to the Millennium Health Signals Report. Urine positivity rates for the two opioids remained flat during 2020.

“Despite the hardships faced during the pandemic, it is encouraging to see that positivity rates for non-prescribed use of hydrocodone and oxycodone have not changed,” said Michael Parr, MD, an addiction treatment specialist and consultant to Millennium.

“Patients requiring opioids for the treatment of pain have faced difficulty obtaining medications, as well as stigma, before the pandemic. Perhaps this data will reassure clinicians who have taken additional steps to safely prescribe these medications during the pandemic.”

There was an uptick in positivity rates for non-prescribed tramadol, a weaker opioid, particularly in Ohio, Tennessee and Kentucky. Millennium said there were more cases of people with substance use disorders using tramadol as their “drug of preference.”

Millennium researchers also found that positivity rates for non-prescribed gabapentin (Neurontin) showed little change in 2020 – but they remain at levels nearly three times higher than positivity rates for oxycodone, hydrocodone and tramadol. The abuse of non-prescribed gabapentin did rise significantly in Ohio and Virginia.

POSITIVITY RATES FOR NON-PRESCRIBED PAIN MEDICATIONS

SOURCE: MILLENNIUM HEALTH

The abuse of gabapentin has been going on for years, but with little public attention. Gabapentin is a non-opioid nerve medication increasingly prescribed for pain, despite the fact many patients say it doesn’t help and has too many side effects. Drug abusers, however, have found that gabapentin can heighten the effect of heroin and other street drugs.

While positivity rates for non-prescribed pain medication were mostly unchanged during the pandemic, they soared for illicit fentanyl and methamphetamine, increasing 78% and 29%, respectively.

After initially increasing in the early stages of the COVID-19 crisis, Millennium found that positivity rates for cocaine and heroin soon returned to pre-pandemic levels.

Another encouraging sign is that positivity rates for carfentanil, a deadly fentanyl analogue, have flatlined to nearly zero. It is unclear why carfentanil abuse has fallen so sharply, but Millennium said it may be because the pandemic has disrupted manufacturing and supply routes from China.     

Home-Based Virtual Reality Reduces Chronic Low Back Pain

By Pat Anson, PNN Editor

A new clinical study has found that home-based virtual reality (VR) therapy can significantly reduce pain levels in people suffering from chronic lower back pain. Patients who watched VR programs also reported better mood, reduced stress and that pain interfered less with their sleep.

The study, published in the Journal of Medical Internet Research, is the first controlled trial to compare home-based VR therapy to a “sham” or placebo treatment for chronic pain. The research was funded by AppliedVR, a Los Angeles-based company that is developing therapeutic VR content to help treat pain and other conditions.

Eighty-nine people used the company’s EaseVRx headset daily for eight weeks, immersing themselves in relaxing and meditative VR programs designed to make their pain seem less important, similar to cognitive behavioral therapy. A control group received the sham treatment, watching routine nature scenes with the headset. All participants had chronic low back pain for at least six months.   

By the end of the study, 87 percent of people in the VR group reported less pain intensity, with nearly two-thirds experiencing at least a 30% reduction in pain compared to the control group. There were also significant improvements in sleep, mood and stress in the VR group.

Importantly, the improvements in pain and other symptoms were cumulative over time – meaning the relief was long-lasting and not just when people were watching VR programs.

“If you look at the results graph, you’re able to see the trajectory of pain and pain intensity very reliably declining over the course of the eight weeks. It’s a really strong time trend. It’s not just a random effect,” explained Beth Darnall, PhD, AppliedVR’s chief science advisor.

You can see the graph below. Over the course of 56 days, average pain intensity fell by 43% in patients using the EaseVRx headset, compared to 23% in the control or sham group.

JOURNAL OF MEDICAL INTERNET RESEARCH

Most of the research to date on VR therapy has focused on treating acute pain in hospitalized patients. AppliedVR is trying to demonstrate that virtual reality can also be used to treat chronic pain at home. A small study released last summer showed that home-based VR therapy reduced pain in people with fibromyalgia and chronic low back pain.

Darnall was hesitant to say if there were any pain conditions that VR therapy might not useful for.

“At the end of the day, pain is pain,” said Darnall, who is a pain psychologist at Stanford University. “This basic approach, in which we’re equipping people with self-regulatory skills, is going to be beneficial and broadly applicable for every pain condition.

“We have multiple studies in progress that are testing this device on different populations. It’s really going to be an exciting year, because there’s going to be an explosion of research that’s really going to inform our understanding of how this may help people across different disease conditions.”   

AppliedVR’s headset received breakthrough device designation from the Food and Drug Administration last year. The company hopes to get clearance from the FDA later this year to begin selling the devices. Due to a recent decision by Medicare to start covering breakthrough medical devices, the company is hopeful that private insurers will also start paying for VR therapy. 

Study Finds Regular Exercise Reduces Migraine Triggers

By Pat Anson, PNN Editor

Two-and-a-half hours of moderate to vigorous exercise a week can significantly reduce migraine triggers like stress, depression and poor sleep, according to a new survey that found more than two-thirds of migraine sufferers do not get enough exercise.

“Migraine is a disabling condition that affects millions of people in the United States, and yet regular exercise may be an effective way to reduce the frequency and intensity of some migraines,” says lead author Mason Dyess, DO, a Senior Fellow at the University of Washington School of Medicine.

“Exercise releases natural pain killers called endorphins, helps people sleep better and reduces stress. But if people with migraine are not exercising, they may not be reaping these benefits.”

The survey involved 4,647 people diagnosed with migraine. About three-fourths of participants had chronic migraine, meaning 15 or more migraines a month. The others had episodic migraine, or up to 14 a month.

Participants completed a questionnaire about their migraines, sleep, depression, stress, anxiety and the amount of exercise they get each week.

Researchers then divided them into five groups based on their level of exercise: those who did not exercise; people who exercised up to 30 minutes per week; those who exercised 31 to 90 minutes; people who exercised 91 to 150 minutes; and participants who exercised more than 150 minutes per week.

Types of exercise that qualified as moderate to vigorous included jogging, very brisk walking, playing a sport, heavy cleaning and bicycling.

Researchers found that only 1,270 participants – about 27 percent -- reported the highest level of exercise. Those who got less than 150 minutes of exercise had increased rates of depression, anxiety and sleep problems:

• Depression was reported by nearly half of people who got no exercise, compared to 25% of those that exercised the most.

• Anxiety was reported by 39% of people in the no exercise group, compared to 28% of people in the high exercise group.

• Sleep problems were reported by 77% of people in the no exercise group, compared to 61% in the high exercise group.

Researchers also found an association between exercise and increased frequency of migraines. Among people in the no exercise group, nearly half had 25 or more headache days per month. That compares to only 28% of people in the high exercise group.

“There are new therapeutics available for migraine, but they are very expensive. People with migraine should consider incorporating more exercise into their daily life because it may be a safe and low-cost way to manage and minimize some of the other problems that often accompany migraine,” said Dyess.

Two-and-a-half hours a week of moderate to vigorous exercise, or 150 minutes, is the minimum amount recommended by the World Health Organization.

The study findings, which will be presented at the annual meeting of the American Academy of Neurology in April, have not yet been peer-reviewed or published. One weakness of the study was that participants self-reported their exercise minutes, rather than having their activity monitored with a device. It also only shows an association between exercise and migraines, and does not prove cause and effect. 

Stem Cells Restore Function in Patients Paralyzed by Spinal Cord Injuries

By Pat Anson, PNN Editor

Intravenous injection of mesenchymal stem cells (MSCs) in patients paralyzed by spinal cord injuries led to significant improvement in their motor functions, according to a team of researchers at Yale University and Sapporo Medical University in Japan.

The study findings, published in the Journal of Clinical Neurology and Neurosurgery, focused on 13 patients who suffered spinal cord injuries (SCIs) after falls or trauma. Some lost the ability to use their arms and legs, while others suffered coordination and sensory loss, or experienced bowel and bladder dysfunction.

For more than half of the patients, substantial improvements in motor function were observed within weeks of being injected with autologous MSCs derived from their own bone marrow. Although this was a small observational Phase 2 study, researchers are excited by the findings.

"The idea that we may be able to restore function after injury to the brain and spinal cord using the patient's own stem cells has intrigued us for years," said senior author Stephen Waxman, MD, a professor of neurology, neuroscience and pharmacology at Yale. "Now we have a hint, in humans, that it may be possible."

One of the patients profiled was a 34-year-old man who was left partially paralyzed and bedridden after a fall. He received an intravenous injection of MSCs 47 days after his injury. Two weeks after the infusion, voluntary movement was restored to his lower extremities and he was walking with the support of a walker.

In another case, a 47-year-old man left bedridden after a diving accident showed rapid improvement after a stem cell infusion. He was able to drive a wheelchair the next day, walk and climb stairs after two weeks, and eat independently after eight weeks.

Other patients paralyzed after similar injuries were able to breath again without assistance, regain control of their bowel functions, and perform independent living tasks such as dressing and grooming.

“Although this initial case study was unblinded and uncontrolled, the SCI patients appeared to demonstrate a tendency of relatively rapid improvement of neurological function that was often apparent within a few days following infusion of MSCs,” researchers said.

“We would emphasize that this case series describes an early study on a small number of patients. In addition to being unblinded and uncontrolled, this study has a number of limitations. We cannot rule out observer bias nor a contribution of surgical intervention to recovery in cases where this intervention occurred, or spontaneous recovery.”

Other case studies have also shown that stem cells can restore motor and sensory function in patients paralyzed by spinal cord injuries.

The Mayo Clinic reported in 2019 that a California man paralyzed from the neck down in a surfing accident was able to walk again after being injected with his own stem cells. Researchers emphasized the man was a “super-responder” and that other paralyzed patients injected with stem cells don’t have such a dramatic recovery.

According to the National Spinal Cord Injury Statistical Center, over 17,000 Americans suffer spinal cord injuries each year. Chronic pain is a serious problem that can result from SCI, affecting about two-thirds of patients, with one out of three reporting their pain as severe.
