‘Game Changing’ Study Finds Cause of Long Covid Brain Fog

By Pat Anson, PNN Editor

Inflamed and leaky blood vessels in the human brain appear to be the cause of brain fog and other cognitive issues in patients with Long Covid, according to a groundbreaking study by a team of Irish researchers.

The discovery that a viral infection may cause cognitive decline could help explain why memory loss, confusion and trouble concentrating is common in patients with other chronic illnesses, such as fibromyalgia, multiple sclerosis and chronic fatigue syndrome (ME/CFS).

Scientists at Trinity College Dublin and FutureNeuro used a specialized MRI to compare the brains of Long Covid patients with brain fog to those without brain fog.

The MRI images show how Long Covid can affect the brain’s delicate network of blood vessels. Patients with brain fog (right column) have significantly more inflammation and blood vessel leakage than those without brain fog (left column).

Patients with brain fog also had more elevated levels of glial fibrillary acidic protein (GFAP) in their blood, which is a sign of cerebrovascular damage often found in patients with repetitive head trauma.

The images and findings are published in the journal Nature Neuroscience.

“For the first time, we have been able to show that leaky blood vessels in the human brain, in tandem with a hyperactive immune system, may be the key drivers of brain fog associated with Long COVID,” said lead author Matthew Campbell, PhD, a Professor in Genetics and Head of Genetics at Trinity College, and Principal Investigator at FutureNeuro. 

“The concept that many other viral infections that lead to post-viral syndromes might drive blood vessel leakage in the brain is potentially game changing and is under active investigation by the team.” 

NATURE NEUROSCIENCE

About 10% of the people infected with the SARS-CoV2 virus develop Long Covid, a broad range of conditions that causes fatigue, shortness of breath, and muscle and joint pain. About half of Long Covid patients also report brain fog or some lingering neurological issue. 

“The findings will now likely change the landscape of how we understand and treat post-viral neurological conditions. It also confirms that the neurological symptoms of Long Covid are measurable with real and demonstrable metabolic and vascular changes in the brain,” said co-author Colin Doherty, Professor of Neurology and Head of the School of Medicine at Trinity, and Principal Investigator at FutureNeuro. 

In recent years, research has found that multiple sclerosis, lupus and other autoimmune conditions are triggered by the Epstein-Barr virus. The exact mechanism is unclear and proving there is a direct link between viral infections and brain fog has been challenging – until now.   

“Our findings have now set the stage for further studies examining the molecular events that lead to post-viral fatigue and brain fog. Without doubt, similar mechanisms are at play across many disparate types of viral infection and we are now tantalisingly close to understanding how and why they cause neurological dysfunction in patients,” said first author Chris Greene, PhD, a research fellow in the School of Genetics and Microbiology at Trinity.

The study was funded by Science Foundation Ireland, the European Research Council and FutureNeuro, a research center for chronic and rare neurological diseases.

My Story: Kratom Helps Treat Fibromyalgia

By Jim Hunter

The following narrative is not meant as medical advice. I am not a medical professional. I am simply relating my own experience.

Most of my adult life I have suffered from a variety of symptoms that were never diagnosed by any of the doctors I saw. Eventually, I became aware that these symptoms seemed to be consistent with the list of symptoms that appear under the heading of fibromyalgia. The most conspicuous symptom was painful muscles all over my body. The one symptom often associated with fibromyalgia that I did not have was insomnia.

Do I actually have fibromyalgia? I don’t know. What I have is an assortment of symptoms that, when compared to a checklist for fibromyalgia, make it look pretty close to that mysterious affliction.  Since there seemed to be no reliable objective signs of fibromyalgia, and I seemed to have almost all the subjective ones, it seemed reasonable to diagnose myself as having it.

I treated it for a long time (years) by taking more ibuprofen than is recommended for pain relief. The ibuprofen did help some, so I took more than I should have. I am not recommending anyone else do this, but I didn’t see an alternative at the time.

Then I discovered kratom. I don’t recall how I happened to run into it. But I discovered that when I took small doses of kratom regularly throughout the day, the fibromyalgia symptoms simply went away. Above all else, I didn’t hurt anymore.

Kratom even cleared up the stomach and intestinal problems. That was a surprise. I figured that anything that tasted as harsh as kratom wouldn’t help my stomach, but it did.

As long as I didn’t take too much kratom, I didn’t have any loopy feelings. I didn’t mind the slightly euphoric sensations it sometimes generated, but I learned to fine tune it so I didn’t experience that. It simply took away all the muscle aches and pains, fatigue and stomach problems. I felt normal again and was productive.

A Complication

That happy state facilitated by kratom lasted for years. But then I ran into a glitch. I got an inguinal hernia that strangulated. The surgeon was able to push it back in, but that was clearly just a temporary solution. Clearly, I needed surgery. One can die a nasty death from a strangulated hernia.

There was a complication about whether the local hospital could do the operation or whether my condition would require a bigger hospital with an intensive care unit. They eventually agreed on the local hospital (which is what I wanted), but the only glitch was that I had barely mentioned my use of kratom and sort of played it down. I was pretty sure most of the professionals in the medical field would be suspicious of it. Kratom is, after all, reported to have a mild opioid-like effect.

I’m 83 years old. I was perfectly willing to take any reasonable risk in surgery. I am not going to live forever, and I suspect that the end will not be decades off.

But I did feel obligated to the hospital that agreed to do the operation. I had to either level with them about the kratom I was taking or get off it. I knew that if I explained everything in detail, it would raise questions again about who should do the operation and when. I imagined there might be an issue with a possible interaction of kratom with anesthesia.

I decided to get off the kratom, at least long enough for the operation. There might be some withdrawal symptoms, but they were described in the literature as mild to moderate and short lived.

So, I began phasing out my kratom, for which I calculated I needed about two weeks. Two weeks stretched into three and then four. I was feeling horrible – considerably worse than what was described as kratom withdrawal. This was neither short, nor mild or moderate.

Then my wife put her finger on the problem. The symptoms for withdrawal and fibromyalgia, though similar, were not exactly the same. I was experiencing less nausea, but more pain. The fibromyalgia was back in full force. At that point, as I saw it, I had no choice. I took a little bit of kratom once again and felt fine, except for the hernia.

It was while on the minimal dose of kratom needed for the fibromyalgia that I went in for surgery. After the operation, the anesthesiologist reported that her part of the operation went well. I was relieved. However, another problem emerged. An expected two or three-hour operation with laparoscopic surgery turned into a seven-hour ordeal.

I still cannot visualize the exact nature of the unexpected problem the surgeon encountered. Apparently, my bladder was drawn into and tangled up with the hernia. The surgeon, who had done this operation thousands of times, had never seen it before and nobody else had heard of it.

The surgeon was able to unravel the problem and repair the hernia. This led to yet another problem. I had expected to be in the hospital most of one day, but they kept me in the hospital overnight and, as far as I knew, might keep me hospitalized even longer.

By three in the morning, I was beginning to experience moderate to severe pain. The medication given to me by the night nurse didn’t touch the pain. I realized I had no choice. I had to confess my sin -- the incomplete and unsatisfactory way I told them about the kratom -- and plead for mercy.

I called in the night nurse and explained the whole thing. She was very nice about it, let the head nurse know right away, and notified the surgeon as soon as he arrived in the morning.

To make a long story short, arrangements were made for me to be released from the hospital so I could resume my regime of small doses of kratom.

I had lots of minor aches and pains from being worked on so hard and so long during the operation, while in an awkward position. They had raised my legs a considerable angle to the ground, expanded the inner cavities of my body with CO2, and done God knows what to separate my scrotum, testicles and whatever else from the hernia. But with some Aleve, these were now manageable pains. 

Do I have any advice? Not really. The nearest thing I can offer is to say that, should the situation rise again, I would simply tell the medical people about my dependence on kratom. And if they insisted that I get off it before they would do the surgery, I would not have the surgery done.

Jim Hunter lives in Maine. He is a retired social worker.

Long Covid Linked to Chronic Pain Conditions

By Pat Anson, PNN Editor

People with chronic pain conditions such as fibromyalgia, chronic fatigue, migraine and irritable bowel syndrome are significantly more likely to have symptoms of Long Covid after a COVID-19 infection, according to a large new analysis.

Researchers at the University of Michigan analyzed electronic health records of over two million Americans and found that the risk of having Long Covid symptoms was higher in people with a chronic overlapping pain condition (COPC).  

Over half the patients (58.6%) with a COPC and a diagnosis of COVID-19 had symptoms of Long COVID, compared to only a third (33.6%) of those without a COPC.

“We hypothesized we’d see an increase in pain and fatigue because it’s something we’ve seen in the past with other infectious diseases, like the SARS outbreak in 2002,” said lead author Rachel Bergmans, PhD, a Research Assistant Professor at U-M’s Department of Anesthesiology, Chronic Pain and Fatigue Research Center. “A big predictor of future pain is having had pain in the past.”

Findings from the retrospective cohort study, published in the journal Pain, do not establish a definitive cause that links chronic pain with Long Covid – only an association.

It’s a bit of a chicken-and-egg situation. Many of the symptoms of Long Covid mirror those of COPCs – such as brain fog, chronic fatigue, headache and body pain – so it’s not clear which condition developed first. Interestingly, Long Covid symptoms were found in 24% of patients with a COPC who were not diagnosed with COVID-19.  

That finding could be explained by a relatively new concept in pain research called neuroplasticity or nociplastic pain – chronic pain that lingers and becomes heightened in the brain and central nervous system (CNS) long after the initial injury heals. 

“With nociplastic pain, some people have what you might call a pain setting turned up in their central nervous system. There’s evidence showing that infections, trauma, and stress can be a trigger for nociplastic pain features and related symptoms,” said Bergmans.

Nociplastic pain could also explain the cognitive dysfunction and other symptoms caused by Long Covid – known technically as post-acute sequelae of SARS-CoV-2 infection (PASC). The basket of symptoms now collectively known as Long Covid may have existed before COVID-19 even came along. In 2022, the CDC estimated that 18 million American adults had Long Covid.

“The onset of long COVID features was relatively common regardless of acute COVID exposure. In addition, those with pre-existing COPCs had an increased risk of being diagnosed with long COVID features. These findings reinforce the likelihood that nociplastic pain is a key mechanism in long COVID and can inform precision medicine therapies that avoid the pitfalls of viewing long COVID exclusively in the framework of infectious disease,” researchers concluded.

“For clinicians who treat people with long COVID, it may be helpful to review the medical record and see whether someone had a pre-existing COPC diagnosis before long COVID onset.”

Bergmans and all of her co-authors are either consultants or employees of Tonix Pharmaceuticals, a company that is developing new non-opioid treatments for fibromyalgia.

Study Finds Low-Dose Naltrexone Works No Better than Placebo

By Pat Anson, PNN Editor

In recent years, low-dose naltrexone (LDN) has grown in popularity as a treatment for fibromyalgia and other chronic pain conditions. Although naltrexone is only FDA-approved for the treatment of substance use disorders, a growing number of patients and providers say low doses of naltrexone prescribed off-label can be effective in relieving pain.

A new study by Danish researchers is casting doubt on the some of those claims, finding that LDN works no better than a placebo in reducing pain for women with fibromyalgia. In their double-blind, placebo-controlled study, 99 adult women with fibromyalgia were randomly assigned to receive either an LDN pill or an identical-looking placebo daily for 12 weeks.

The study findings, recently published The Lancet Rheumatology, found a minor improvement in pain intensity for the LDN group, with a similar pain reduction in the placebo group. There were no serious adverse events in either group.

“This study did not show that treatment with low-dose naltrexone was superior to placebo in relieving pain. Our results indicate that low-dose naltrexone might improve memory problems associated with fibromyalgia, and we suggest that future trials investigate this further,” wrote lead author Karin Due Bruun, MD, a researcher in the Pain Center at Odense University Hospital in Denmark.

The Danish study is notable, because placebo-controlled, double-blind studies are considered the gold standard in medical research. Until now, much of the evidence about LDN has been anecdotal or low quality.

In a 2020 review of nearly 800 LDN studies, another research team could find only eight that were high quality enough to meet their criteria for evaluation. Nevertheless, they found that LDN “provides an alternative in medical management of chronic pain disorders.”

A 2019 review by British researchers also found that LDN is safe to use, but recommended that more clinical studies be conducted.

How naltrexone works is not exactly clear. LDN supporters believe the drug modulates the immune system, reduces inflammation and stimulates the production of endorphins, the body's natural painkiller.

In 50mg doses, naltrexone blocks opioid receptors in the brain and decreases the desire to take opiates or alcohol. But in smaller doses of 5mg or less, patients have found LDN to be an effective pain reliever. PNN columnists have shared their positive experiences using LDN to treat everything from interstitial cystitis to Ehlers-Danlos syndrome to fibromyalgia.  

A woman with fibromyalgia tried all sorts of FDA-approved medications to relieve her leg pain, brain fog and depression. None worked, until she tried LDN.   

“After about seven days, my pain lessened,” said Janice Hollander. “[LDN] has completely changed my life. I don’t know that I would be here today if it wasn’t for it. I don’t think I could go for another year in the misery I was in.” 

Naltrexone does cause minor side effects, such as nausea and dizziness, and because it is an opioid antagonist it should not be taken with opioid medication.

Patients interested in trying LDN often encounter doctors who won’t prescribe it off-label. The LDN Research Trust includes a list of LDN-friendly doctors and pharmacies on its website.

Patients With Irritable Bowel Syndrome Have High Rates of Fibromyalgia

By Pat Anson, PNN Editor

A large new study has found high rates of fibromyalgia in patients with irritable bowel syndrome (IBS), adding to a growing body of evidence linking gut bacteria to chronic pain disorders. IBS patients were also more likely to have chronic fatigue syndrome (CFS).

The study, recently published in the journal Biomedicines, looked at more than 1.2 million IBS patients hospitalized in the U.S. over a three-year period. They found that the prevalence rate of fibromyalgia in the IBS patients was 10.7 percent, about five times higher than the fibromyalgia rate (1.4%) in the general adult population.

Fibromyalgia is a poorly understood condition characterized by widespread body pain, headaches, fatigue, insomnia and mood disorders; while IBS causes abdominal pain, cramps, bloating, gas and diarrhea. Gut bacteria has been associated with both IBS and fibromyalgia, but the exact mechanism of action remains unclear.

“This is yet another example where ailments in the gut are linked to ailments elsewhere in the body and mind,” said senior author Yezaz Ghouri, MD, an assistant professor of clinical medicine and gastroenterology at the University of Missouri School of Medicine. “As we continue to learn more about how gut health effects health elsewhere it is important that clinicians look for and manage somatic comorbidities in IBS patients.”

Fibromyalgia and CFS are known as “somatic” disorders because patients who have them often experience anxiety and depression – a tendency perhaps explained about the lack of effective treatments for their physical symptoms.

“Because IBS patients have higher prevalence of somatic comorbidities such as fibromyalgia and chronic fatigue syndrome, identifying and treating these disorders can improve their quality of life,” said lead researcher Zahid Ijaz Tarar, MD, a fellow in the division of gastroenterology and hepatology at the University of Missouri School of Medicine.

“Earlier identification of comorbidities is valuable to inform treatment strategies, including consulting other specialties such as rheumatology and psychiatry to improve the overall health outcomes in IBS patients.”

In addition to fibromyalgia, the research team found that hospitalized IBS patients were also significantly more likely to be white and female.  Less than one percent (0.42%) had a CFS diagnosis – a small percentage to be sure, but still higher than CFS rates in the general population (0.06%).

The high rates of fibromyalgia and CFS in IBS patients has led to speculation that poor diets or antibiotics may cause an imbalance of “bad” bacteria in the gastrointestinal system, allowing toxins to leak into the bloodstream and cause other health problems.

A recent study found that Klebsiella aerogenes, a bacterium that causes white blood cells to produce excess amounts of histamine, can trigger a painful immune system response.

Another study found that women with fibromyalgia have strikingly different types and amounts of bacteria than those without fibromyalgia. Faecalibacterium prausnitzii, a “good” bacterium that is normally abundant in the human gut, was found to be depleted in fibromyalgia patients. Other bacteria associated with IBS, CFS and interstitial cystitis were found to be abundant in fibromyalgia patients, but not in the healthy control group.  

Mood Disorders May Be Early Sign of Chronic Fatigue

By Pat Anson, PNN Editor

Anxiety, depression and other mood disorders have long been associated with fibromyalgia, irritable bowel syndrome (IBS), and chronic fatigue syndrome (CFS). That’s not altogether surprising, since the three chronic illnesses cause body pain, insomnia, fatigue, and other stressful symptoms that can trigger a psychological reaction. No one likes being sick, after all.  

But a large new study found that psychiatric disorders preceded the development of fibromyalgia, IBS and CFS in about a quarter of the people who have the conditions – more than those who suffer from similar chronic illnesses. Anxiety and depression were significantly more common in people who were later diagnosed with chronic fatigue.

"This work provides evidence that for many people, a wide variety of physical and psychological factors are associated with these debilitating conditions," says Francis Creed, a professor emeritus of psychiatry at The University of Manchester.

Creed analyzed over two years of health data from over 120,000 people who participated in the Dutch Lifelines cohort study; comparing the data of people with fibromyalgia, IBS and CFS to those with diabetes, inflammatory bowel disease (IBD) and rheumatoid arthritis. The latter group had similar symptoms and served as a control.

Creed’s findings, recently published in the journals PLOS ONE and Frontiers in Psychiatry, showed that psychiatric disorders were more common (17–27%) in the first group than in the control group (10.4–11.7%).

General anxiety disorder (GAD), panic disorder, dysthymia, major depressive disorder (MDD) and agoraphobia were particularly more common in people who were later diagnosed with CFS.  

PLOS ONE

Creed says a number of physical and mental health issues may be at work in the development of fibromyalgia, IBS and CFS. He favors a holistic approach to treating them, including a mental health evaluation.   

"When people suffering from CFS/ME, IBS and fibromyalgia come into contact with health professionals, negative attitudes can sometimes get in the way of treatment. but by understanding these complex conditions better, the stigma and mystery around them can be eased," he said.

"Although there are symptomatic treatments which may help these unexplained disorders, we should aim to understand fully their underlying causes. There are probably several different ways they may develop; a whole range of physical and mental factors are probably involved. Treatment approaches will become more effective as our understanding of the causes improves."

Association is not causation, and it’s important to note that about three-quarters of the people who developed fibromyalgia, IBS and CFS did not have any mood disorders prior to the onset of their illnesses.   

Creed says future research and clinical work should focus on possible interactions between psychiatric disorders and other behavioral variables to identify the true role of anxiety and depression in chronic illness.

FDA Authorizes Smartphone App for Fibromyalgia

By Pat Anson, PNN Editor 

The U.S. Food and Drug Administration has authorized the marketing of the first smartphone-based digital therapy for fibromyalgia. The Stanza mobile app doesn’t relieve the physical pain of fibromyalgia, but is designed to help patients manage the anxiety, depression and other psychological symptoms that often come with fibromyalgia.

Fibromyalgia is a poorly understood condition characterized by widespread body pain, headaches, fatigue, insomnia and mood disorders. The FDA has approved only three medications for fibromyalgia -- duloxetine (Cymbalta), milnacipran (Savella), and pregabalin (Lyrica) – but many patients consider the drugs ineffective or have too many side effects.

“This represents a major milestone both for our company and the fibromyalgia patients we serve, and is a big step towards meaningfully addressing patient access barriers by making evidence-based, non-drug treatments available to more people,” said Mike Rosenbluth, CEO of Swing Therapeutics, the maker of Stanza.

“On top of dealing with the debilitating symptoms, fibromyalgia patients have been historically underserved and even stigmatized. Current FDA-approved medications, while offering moderate efficacy, are often accompanied by side effects.”  

The Stanza app provides training in acceptance and commitment therapy (ACT), a form of cognitive behavioral therapy (CBT), to help patients develop flexibility and resilience in coping with fibromyalgia. ACT teaches mindfulness strategies and behavioral changes to help people accept and manage their pain.

In a clinical trial, Stanza significantly reduced depression and anxiety in fibromyalgia patients, while improving their quality of life. About 80% of patients responded to Stanza therapy and the benefits were sustained for up to 12 months.

Stanza is designed to be used five to seven days per week, for about 15 to 20 minutes a day, over a 12-week period. After 12 weeks, the app can be used as needed.

Stanza is only available by prescription. It was first made available last year under the FDA’s Digital Health Enforcement Policy for Digital Health Devices. Swing Care, an online clinic that provides personalized treatment of fibromyalgia, includes Stanza as an option for patients in Texas. Swing Therapeutics anticipates that Stanza will also be available through Swing Care in other states later this year.

We Need Better Treatments for Long Covid, Fibromyalgia, Chronic Fatigue and More

By Dr. Seth Lederman

Headlines about COVID have faded, and the United States will soon turn the page on public emergency status for the pandemic. The virus no longer dominates most of our lives, yet there are still thousands of new hospitalizations daily and an estimated 15 million Americans currently suffer from Long COVID.

The deep impact of long-haul cases has contributed to a surge of patients with disabling conditions, who are often misdiagnosed or treated ineffectively. More than one in five people infected with COVID-19 develop Long COVID and its constellation of physical and neurological symptoms. The persistent pain, fatigue, sleep problems and brain fog are similar to two other post-infectious syndromes, fibromyalgia and chronic fatigue syndrome (CFS/ME).

A recent study of both conditions and Long COVID documented that the physical and cognitive impairments of Long COVID were exacerbated in people previously diagnosed with CFS/ME or fibromyalgia. These types of chronic overlapping pain conditions have long been recognized by the National Institutes of Health (NIH), and the president’s National Research Action Plan on Long COVID similarly makes the connection between CFS/ME and Long COVID.

More than 50 million people struggle with these neurological illnesses every year in our country, and the burden of their chronic diseases comes at incalculable personal harm, along with billions of dollars in healthcare costs and lost productivity. 

There is one common denominator among all these unrelenting illnesses: the human brain. Physicians like me who study infectious and neurological diseases know that getting a drug’s active ingredients into the brain is not easy. Unlike biologic drugs, which are usually administered by injection, the only medications that can cross from the bloodstream into the brain are small-molecule drugs.

But big pharmaceutical companies have largely abandoned the development of new small-molecule therapeutics, instead pursuing biologic drugs which tend to be more expensive and profitable. That is because of a complex mix of federal laws granting longer market exclusivity to biologics, patent law changes that remove economic incentives to develop new small-molecule therapeutics, and mounting Food and Drug Administration hurdles.

Yet small-molecule drugs can be highly effective and life-changing, as well as relatively cost-effective to manufacture and distribute. They are our best hope for offering real relief to people struck by cruel conditions rooted in brain function.

As we pick up the pieces from a once-in-a-generation pandemic, we cannot ignore the rise in debilitating post-infectious diseases. In a sense, the people afflicted by these illnesses are living with invisible scars from the infections that preceded their current illnesses. There is an urgent need to help them by restoring incentives for small-molecule drug development and streamlining regulatory processes for new treatments.

The government should be accelerating efforts to expand its support for new drug therapies to address fibromyalgia, CFS/ME, Long COVID, and other illnesses that originate in the brain. The untapped potential of emerging therapeutics is unacceptable, as is the fact that many patients’ symptoms are frequently misinterpreted or dismissed.

It is good news that the Advanced Research Project Agency for Health has been established within NIH to pursue biomedical breakthroughs. But our country could still be doing more on this front. Congress has the power to legislate a more level playing field for small-molecule drug development, correcting decades of bureaucratic bias.

Lawmakers should appropriate more resources to fast-track clinical trials and scale-up delivery of novel therapies for post-infectious diseases. Public-private partnerships could also go a long way towards bridging the gap between treatments that would transform patients’ lives and their current limited options.

We know from our experience with COVID that medical science is capable of swift and significant breakthroughs. Our public health system should be equipped to readily diagnose and effectively treat people with fibromyalgia, CFS/ME, Long COVID, and similar devastating illnesses.

While the symptoms of these diseases are often not visible, our responsibility to provide patients with advanced and effective care is very real. For millions of Americans and their families, the time for better treatments is now.

Fibromyalgia Treatment Is a Real Gas

By Pat Anson, PNN Editor

Immersing fibromyalgia patients in high levels of oxygen is more effective at treating their pain and other symptoms than two medications commonly prescribed for the disorder, according to a new study.

Researchers at Tel Aviv University have been studying hyperbaric oxygen therapy (HBOT) for years as a possible treatment for fibromyalgia, a poorly understood condition characterized by widespread body pain, headaches, fatigue, depression and insomnia.  

Hyperbaric medicine is a form of treatment in which patients stay in a pressurized chamber and breathe 100% oxygen to help them heal faster. HBOT has long been used to treat infections, severe burns, carbon monoxide poisoning, and even scuba divers recovering from decompression sickness. The higher air pressure allows lungs to gather more oxygen than they would normally, and promotes the growth of new blood vessels and neurons in the brain.

In a 2015 study, researchers found that HBOT can also induce neuroplasticity in the brain and significantly reduce fibromyalgia pain.

"Until 15 to 20 years ago, there were doctors who believed that it was a psychosomatic illness and recommended that patients with chronic pain seek mental health care¸” said Shai Efrati, MD, of the Sagol Center for Hyperbaric Medicine and Research at Shamir Medical Center. “Today we know that it is a biological illness, which damages the brain's processing of the signals received from the body. When this processing is malfunctioning, you feel pain without any real damage in related locations.”

Efrati and his colleagues recruited 64 adults who suffer from fibromyalgia as a result of a traumatic head injury, and randomly assigned them to two groups.

One group was exposed to 100% pure oxygen in a hyperbaric chamber for 90 minutes, five times a week for three months; while the second group received either pregabalin (Lyrica) or duloxetine (Cymbalta), two FDA-approved medications for fibromyalgia.

The study findings, published in PLOS One, show that HBOT induced significant improvement in pain levels, quality of life, and emotional and social function. The clinical changes were correlated with increased brain activity in the frontal and parietal regions of the brain, which are associated with function and emotional processing.

A HYPERBARIC oxygen CHAMBER. 

"The results were dramatic," said Efrati. "At the end of the treatment, 2 out of 5 patients in the hyperbaric treatment group showed such a significant improvement that they no longer met the criteria for fibromyalgia. In the drug treatment group, this did not happen to any patient.

"In the group that received hyperbaric treatment, you could see the repair of the brain tissue, while in the control group there was only an attempt to relieve the pain -- without treating the damaged tissue -- and of course the medication group experienced the side effects associated with drug treatment.”

Duloxetine is an anti-depressant and pregabalin is an anti-seizure medication. Neither drug was initially developed to treat fibromyalgia, but were later repurposed as pain treatments.

"These drugs are not very effective,” said lead author Jacob Ablin, MD, from the Tel Aviv Sourasky Medical Center. "As a whole, existing treatments are not good enough. It is a chronic disease that significantly affects the quality of life, including young people, and hyperbaric medicine meets an acute need of these patients.”

Ablin says other non-pharmacological treatments are also beneficial for fibromyalgia, such as aerobic activity, hydrotherapy, cognitive-behavioral therapy and Tai Chi. He said quite a few patients request treatment with medical cannabis.

The studies are preliminary, and researchers say more long-term studies are needed to gauge the effects of HBOT after one, two and three years. But they’re encouraged by what they’re finding.

"This is a difference in approach: to cure instead of just treating the symptoms,” says Efrati. “Our goal as doctors is not only to treat the symptoms but to treat as much as possible the source of the problem, thus improving the quality of life of fibromyalgia patients."

Experimental Blood Test Could Improve Fibromyalgia Treatment

By Pat Anson, PNN Editor 

Finding effective treatment for fibromyalgia has always been problematic. The Food and Drug Administration has approved three drugs for fibromyalgia, but many patients find pregabalin (Lyrica), duloxetine (Cymbalta) and milnacipran (Savella) ineffective in treating the widespread body pain, fatigue, depression and “brain fog” that are common symptoms of fibromyalgia.  

A small pilot study suggests an experimental blood test for fibromyalgia – called FibroGENE -- could be used to determine which drug works best for each patient. Researchers at AMPEL BioSolutions and Duke University Medical Center found genetic biomarkers in the blood cells of 18 lupus patients with fibromyalgia-like symptoms. Their findings, published in the journal Lupus Science and Medicine, could lead to patients getting more effective, personalized treatment through genetic profiling.

“The bottom line is that we found the driving pathways for fibromyalgia that can be targeted by drugs that are already on the market,” said Amrie Grammer, PhD, Ampel’s co-founder and President.

“This is a disease management tool. This is meant for patients who know they have fibromyalgia, either on its own or in the context of another disease, such as lupus, and will be a game changer because treatment is often by trial and error. The doctor says, ‘Try this, let me know if it doesn’t work and try that.’ It often takes years, if ever, to get on a medication or medications that relieve the brain fog, the pain, etc.”  

Lupus is an autoimmune disease in which the body attacks its own tissues and organs, causing pain and inflammation. Like fibromyalgia, lupus is difficult to diagnose because its symptoms mimic those of other pain conditions. Genetic profiling of patients helps reduce the guesswork in treatment.

“The gene expression profiles of patients with fibromyalgia or type 2 lupus with fibromyalgia suggest both available drugs and new drugs that might be tested in patients with extensive pain and fatigue,” says study co-author David Pisetsky, MD, Rheumatologist and Professor of Medicine at Duke.

“Moreover, the gene expression profiles suggest a means to match patients with specific drugs. This opens a novel area of precision therapeutics for each individual patient rather than the trial and error approach currently employed.”

Larger studies are needed to prove the viability of Ampel’s blood test, but the company’s goal is to make FibroGENE commercially available by 2024 or 2025. Ampel is currently looking for fibromyalgia patients to participate in its clinical trials.

The Healthcare System Is Sick, How Could It Ever Heal Us?

By Mia Maysack, PNN Columnist

As a person who has required ample medical attention throughout my life, a constant part of the never-ending struggle for treatment is finding a provider that’s worth-a-damn to administer quality healthcare.

In childhood, I was fortunate to have one practitioner who treated every member of my family. Although most of it was an excruciating trial and error process, I can at least say they tried. When she retired, for continuity’s sake I gravitated toward someone else in the same medical practice.

By then my initial condition (chronic head pain) had not only become more complicated, but I was also battling another diagnosis (fibromyalgia) -- one that the new provider did not seem to take seriously. I chose to dismiss myself from the practice.

At that point, I became more conscious about the sort of doctor I was seeking, so I spent hours researching every clinic in my surrounding area and reviewing doctors’ bios. It was imperative that whoever I chose possess some sort of background or special interest in pain. 

I found a candidate I was so excited about that I left in happy tears after the first appointment. Unfortunately, that did not last long. On the next visit, I was diagnosed with my second round of Covid-19 and they proceeded to blame my chronic fatigue, joint pain and compromised mobility on the coronavirus -- as opposed to the fibromyalgia I’d already been diagnosed with years before the pandemic.

I shrugged it off as a misunderstanding, and assumed they must have meant the exacerbation of my fibromyalgia symptoms was caused by Covid.  

At appointment number three, we discussed preventative screenings due to some issues relating to potential hereditary concerns. After some urging, they explained the process of going in for testing, assured me I’d be contacted by qualified personnel, and guaranteed that I’d receive a direct message from them personally once all this was set in motion.

My only job was to wait, so I did. And I continued to wait. A month later, I’m still waiting.

Of course, I realize I’m not the only patient in the universe. As a retired healthcare worker, I understand the burnout so many providers must be experiencing after the last 3 years.  I recognize the shortages and feel privileged to have any sort of access. That being said, over the last two months at least two members of the pain community have taken their own lives. This is an example of what led them there. 

I vowed this was going to be the final disappointment that I am willing to accept from the healthcare system. I am paying more for medical insurance than I ever have, but receive the least amount of aid.

Given that previous failures are what led me to explore more holistic methods, I do not reside in woo-woo land. Concepts like breath work and herbs felt a bit degrading and insulting at first, but then I decided to set my reluctance aside, remembering how lost just about everything I tried up to then had left me. I reflected on the fact that I almost didn’t survive long enough to even consider something different. 

I’d never suggest that natural treatments will cure whatever horrendous illness a person may be enduring, but I’ll point out that many holistic remedies go back thousands of years. Ideas that were once dismissed, such as gut health being correlated to mental well-being; inflammation being the main culprit in overall sickness; oral hygiene (or lack thereof) directly impacting the heart; and how exercise improves mood and health are now widely accepted as mainstream.

Some of these ideas have gained traction, but utilizing things like plants won’t ever be fully encouraged or supported because it takes money away from Big Pharma – which ironically produces medication that is often derived from natural sources as well.

All of this is an open invitation to explore different ways to care for ourselves. We can remain distraught over our lack of support or we can be empowered by seeking out what we can do, as opposed to what they’ll “allow.”

I don't know about you, but continuing to put the quality of my life in the hands of those who repeatedly demonstrate their lack of concern and who are in the business of profiting off sickness is a death wish. The healthcare system is not only guilty of this, but sick itself. How could it ever heal us?

My Story: How I Was Medically Gaslighted

By Preslee Marshall, Guest Columnist

I remember the first time I experienced what felt like an electric shock sensation. It was a sudden zap out of nowhere, and I wasn’t sure what to make of it. 

It started happening about once a month, then turned into once every two weeks. Before I knew it, this painful experience was happening several times a day with no apparent explanation. 

Recognizing that the pain I was feeling wasn’t normal, I went to a walk-in clinic to get answers. 

I went over my symptoms with a doctor and was told, “It’s probably just fibromyalgia. Do Tai Chi, it should help with that.”  

Confused, I asked the doctor to spell out what fibromyalgia was, as I hadn’t heard of it before. The way it was brushed off with “do Tai Chi,” I figured it couldn’t be too serious. 

Finding information online about fibromyalgia didn’t take much time or effort. This chronic disorder causes pain and tenderness throughout the body, fatigue and trouble sleeping. One thing that stood out to me was how some people with fibromyalgia wind up on disability.  

On the one hand, I could see the seriousness of fibromyalgia and how it can change people's lives. But on the other hand, I’m told to “do Tai Chi” with no official diagnosis or test.

What if the doctor was wrong? 

PRESLEE MARSHALL

I decided to contact another medical professional about my symptoms and to get testing done to rule out other possible conditions. I called my family doctor (sweet lady, but her office is too far from me) and told her what was happening. She brought up a few ideas on what she thinks could be the problem, such as multiple sclerosis or fibromyalgia, and sent in a referral for me to see a neurologist, which was a 6-month wait.  

As my pain worsened, I knew I couldn’t wait six months, so I called the walk-in clinic again and said that if it was fibromyalgia, then I should be sent for testing to determine that. I begged for an MRI test to rule out other illnesses, which I thought would help tremendously. I knew I needed to get referred as soon as possible if I wanted answers. 

The clinic assured me that the neurologist would send me for those tests anyway, and that there was no point in doing it now. In my heart, I knew that it wouldn’t be that easy. It took some convincing, but the clinic finally agreed to send the referral for an MRI.  

‘Get Your Nails Done’ 

After a long wait, it was finally time to see the neurologist, who I thought would solve my problems. I was wrong.  

The first question I was asked was if I had anxiety. After answering yes, I could tell that he was sold on that being the problem.  I’ve struggled with social anxiety for as long as I remember. I knew that this was not the case and said that to him.  

“It’s all in your head,” he said at the end of the appointment. “If you get your nails done, you’ll feel better.”  

I was shocked and devastated. I walked into the lobby, went straight to the bathroom, and cried. I knew the pain was real, but felt hopeless, wiping away my tears to head home.  

That same month, just to prove to myself that I didn’t imagine my symptoms, I got a manicure, pedicure, massage and facial. And I still felt awful! I needed to prove to the doctor that he was wrong. I had my upcoming MRI to look forward to. 

The day came and I got the MRI. The imaging test ruled out multiple sclerosis as a possibility, as well as other conditions. I brought those results back to my family doctor, who referred me to a rheumatologist.  

After seeing the MRI results, asking me a few questions, and giving me a pressure point test, the rheumatologist diagnosed me with fibromyalgia. At that point, it had been over a year and a half since I started noticing the symptoms. I felt grateful to finally have a diagnosis. 

Word of the Year 

After such a long ordeal and less-than-ideal treatment by medical professionals, I’m on a mission to raise awareness about medical gaslighting. 

Merriam-Webster, the oldest dictionary publisher in the United States, recently picked "gaslighting" as its word of the year. There are different forms of gaslighting, which Merriam-Webster defines this way: 

“Psychological manipulation of a person… that causes the victim to question the validity of their own thoughts, perception of reality, or memories and typically leads to confusion, loss of confidence and self-esteem, uncertainty of one's emotional or mental stability, and a dependency on the perpetrator.” 

Medical gaslighting is when a healthcare provider makes a patient feel as though their perception of their own symptoms is false. A common phrase being, “It’s all in your head.” 

In my case, it was “do Tai Chi” and “get your nails done.”  

After suffering for well over a year and having medical professionals dismiss my symptoms, I realized that it was up to me to get myself properly diagnosed. 

I’d like to remind others who are struggling not to give up. It can feel like an impossible never-ending situation, but there are people in the medical field who will listen.

‘Promising Results’ for Low-Dose Naltrexone as Pain Reliever

By Pat Anson, PNN Editor

Low-dose naltrexone (LDN) continues to get more recognition from the medical community as a treatment for some types of chronic pain.

In a review of 47 studies on the off-label use of LDN, researchers at the University of Kansas Medical Center found “promising results” that naltrexone improves pain and function and reduces symptom severity in patients with chronic inflammatory or centralized pain. Most of the studies were small, however, and larger clinical trials are needed to demonstrate LDN’s efficacy.

“Though the results look promising, further, more well controlled studies are required before formal recommendations can be made,” said lead author Adam Rupp, DO, who will present his findings this week at the annual meeting of the American Society of Regional Anesthesia and Pain Medicine (ASRA) in Orlando, Florida.

Naltrexone is an inexpensive generic drug that is only approved by the Food and Drug Administration as a treatment for substance abuse. In 50mg doses, naltrexone blocks opioid receptors in the brain and decreases the desire to take opiates or alcohol.  

But in smaller doses of 5mg or less, patients with fibromyalgia, interstitial cystitis, intractable pain and other chronic conditions have found LDN to be an effective pain reliever. But because LDN is prescribed “off label” for pain, much of the evidence supporting LDN is anecdotal.

How naltrexone works is not entirely clear, but LDN supporters believe the drug helps modulate the immune system, reducing inflammation and stimulating the production of endorphins, the body's natural painkiller. LDN is not recommended for people currently taking opioid medication because it blocks opioid receptors and may cause withdrawal.

In their literature review, Rupp and his colleagues found that LDN improved physical function, sleep, mood, fatigue and quality of life in patients with Complex Regional Pain Syndrome (CRPS), fibromyalgia, diabetic neuropathy, Crohn’s disease, rheumatoid arthritis and low back pain. In patients with Crohn’s, improvements were also noted in the colon’s appearance during colonoscopies.

Side effects from LDN were minimal, consisting most commonly of vivid dreams, headaches, diarrhea and nausea. Most of the side effects resolved with continued use of LDN.

“The evidence in this review provides support for the off-label use of LDN for various chronic
inflammatory or centralized pain conditions. However, it is apparent that high-quality controlled studies focusing on administration, dosing and follow up time are needed before formal recommendations can be made,” Rupp said.

“Despite the current paucity of high-quality evidence in the literature, LDN continues to offer promising results in the management of symptoms in patients with chronic inflammatory or centralized pain conditions.”

Because LDN is not recommended as a pain treatment by the FDA or professional medical societies, patients interested in trying it often encounter doctors who refuse to prescribe it or don’t know anything about it. The LDN Research Trust includes a list of LDN-friendly doctors and pharmacies on its website.

Brain Changes Found in Patients with Long-Term Lyme Disease

By Pat Anson, PNN Editor

Researchers at Johns Hopkins University have documented changes in the brains of patients with post-treatment Lyme disease that may explain symptoms such as brain fog, memory loss and other cognitive issues. The finding could also have implications for patients with long covid, fibromyalgia, multiple sclerosis, chronic fatigue and other health conditions who have cognitive problems.    

Lyme disease is a bacterial illness spread by ticks that causes a rash, flu-like aches and fever, joint pain and fatigue. Most patients fully recover when treated early with antibiotics, but up to 20% of those with post-treatment Lyme disease (PTLD) have long-term symptoms, including depression, insomnia and cognitive difficulties. There is usually no clinical or laboratory evidence to explain their ongoing issues.

“Objective biologic measures of post-treatment Lyme symptoms typically can’t be identified using regular MRIs, CT scans, or blood tests,” says John Aucott, MD., director of the Johns Hopkins Lyme Disease Clinical Research Center.

Aucott and his colleagues recruited 12 PTLD patients and 18 people without a history of Lyme to undergo functional MRI (fMRI) scans while performing a short-term memory task. The scans allow investigators to track blood flow and other changes in the brain in real time.

Their findings, published in the journal PLOS ONE, suggest that cognitive difficulties in PTLD patients are linked to functional and structural changes in the “white matter” of the brain, which is crucial for processing and relaying information. The imaging tests revealed unusual activity in the frontal lobe, an area of the brain responsible for memory recall and concentration. Patients with post-treatment Lyme needed longer periods of time to complete the memory task.

“We saw certain areas in the frontal lobe under-activating and others that were over-activating, which was somewhat expected,” said lead author Cherie Marvel, PhD, an associate professor of neurology at Johns Hopkins.

“However, we didn’t see this same white matter activity in the group without post-treatment Lyme.”

To confirm their finding, researchers used another form of imaging called diffusion tensor imaging (DTI) on all 12 patients with Lyme and 12 of the non-Lyme participants. DTI detects the direction of water movement within brain tissue. Water was diffusing, or leaking, in the the same white matter regions identified in the fMRI.

Researchers believe the increased activity they saw in white matter may reflect an immune system response in the PTLD patients, which may also explain cognitive issues in patients with other chronic health conditions.

PLOS ONE

“Results reported here may have implications for other diseases in which white matter pathology has been demonstrated (e.g., multiple sclerosis) or in illnesses in which cognitive complaints follow disease onset,” researchers said. “The use of multimodal neuroimaging methods, like the ones used in the current study, may be a viable approach for obtaining information on brain function and structure to identify biomarkers of disease burden.”

Researchers say larger studies with more patients will be needed to confirm their findings, as well as long-term tracking of brain changes from the initial Lyme infection through development of PTLD.

Nearly 500,000 people are believed to get Lyme disease each year in the United States. Diagnoses of Lyme have soared over the past 15 years, according to a recent analysis of insurance claims that found Lyme cases rose 357% in rural areas and 65% in urban areas. The highest rates of Lyme were in New Jersey, Vermont, Maine, Rhode Island and Connecticut.

Green Eyeglasses Improve Anxiety and Wellness in Fibromyalgia Patients

By Pat Anson, PNN Editor

Fibromyalgia is well known as one of the most difficult chronic pain conditions to treat. The Food and Drug Administration has approved a handful of medications for fibromyalgia, but many patients find them ineffective in treating the muscles aches, joint pain, fatigue, anxiety and other symptoms that are common in fibromyalgia.  

Researchers at Duke University may have found an easy way to reduce some of those symptoms without the use of drugs. In a small study of fibromyalgia patients being treated with opioids, those who wore eyeglasses with specially tinted green lenses reported a significant improvement in their anxiety and overall sense of wellness. And while their pain levels were unchanged, their use of opioids declined.

“My research has been focused heavily on finding alternatives to opioids for pain management,” says lead author Padma Gulur, MD, Executive Vice Chair of the Department of Anesthesiology at Duke University. “One of the things we discovered early on was that there were visually mediated triggers for pain. We definitely could see that with headaches, but also that it could actually impact pain itself, the pain pathways. While we still don’t fully understand the mechanism of how pathways for pain get activated with visual mediation, it definitely does happen.

“We narrowed it down over some years to the hypothesis that with green light, particularly in the green spectrum, there was an opportunity where it was influencing pain, both chronic pain and acute pain.”

Previous research has found that green light therapy has a calming effect on the brain and is useful in treating fibromyalgia and migraines. But in those studies, participants were confined to a room where they were immersed in green light and told to avoid activities like watching TV or using their cellphones.

Gulur thought there must be an easier way to experience the benefits of green light.

“People want pain relief, but they also want to live their lives. And spending hours and hours in a room or exposure takes away from that quality of life,” she told PNN. “On the other hand, wearing eyeglasses is something we’re all very comfortable doing and, thankfully these days, colored eyeglasses are all the thing.”

Gulur and her colleagues studied 34 fibromyalgia patients who were randomly selected to wear various shades of eyeglasses at least four hours a day for two weeks: 10 patients wore blue eyeglasses, 12 wore clear eyeglasses and 12 wore green eyeglasses.

DUKE UNIVERSITY

Their findings, presented this week at the annual meeting of the American Society of Anesthesiologists, showed that participants who wore green eyeglasses were four times more likely to have reduced anxiety than those in the other two groups, who reported no reduction in anxiety. They also reported feeling better.

“We found that although their pain scores remained the same, those who wore the green eyeglasses used fewer opioids, demonstrating that their pain was adequately controlled,” said Gulur, who noted that patients who wore the green eyeglasses asked if they could keep them at the end of the study.

“They didn’t want to give them back. We had no trouble getting the blue and the clear back, but none of them wanted to return the green glasses.”

Unfortunately, they had to give them back. The eyeglasses are specially formulated to filter a specific wavelength on the green light spectrum and were needed for further study. You can’t buy the glasses online or at your local drug store. At least not yet.

Gulur and her team are planning further studies with green eyeglasses on patients with diabetic neuropathy and chronic back pain.
