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.

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.

Strict Low-Calorie Diet Reduces Fibromyalgia Symptoms

By Pat Anson, PNN Editor

Fibromyalgia patients with obesity experienced a significant reduction in pain and other symptoms after three weeks on a strict low-calorie diet, according to a new study that suggests limiting calories – not just weight loss – can have an analgesic effect.

Researchers enrolled nearly 200 patients diagnosed with fibromyalgia who were participating in a weight management program at the University of Michigan Health System. Participants had an average body mass index (BMI) of 41, which is considered severe obesity.

For 12 weeks, they were put on a very low energy diet (VLED) that limits bread, rice, potatoes and other foods that are high in carbohydrates. VLED is designed to shift the body away from using glucose in sweet or starchy foods to burning its own body fat for energy. Study participants were limited to just 800 calories a day, less than half the amount recommended for adult women and only a third of the amount recommended for men.

After just three weeks on the restricted diet, nearly three out of four participants (72%) experienced symptom reductions of 30% or more, regardless of the amount of weight lost. Patients who showed little or no improvement had a higher BMI at the start of the study and were more likely to have had a diagnosis of depression.

“Our results show, for the first time, that individuals following aggressive calorie restriction, ie, a VLED, had rapid and significant improvements in pain distribution and common pain-related comorbid symptoms and, importantly, prior to the achievement of significant weight loss,” researchers reported in the journal ACR Open Rheumatology.

“Furthermore, improvement at week 3 was strongly associated with improvement over the entire 12-week course of VLED, suggesting that patients who respond are likely to show these effects early in the process. These findings provide preliminary support for the hypothesis that calorie restriction, per se, can reduce pain and comorbid symptoms in individuals with obesity.”

Fibromyalgia is a poorly understood disorder characterized by widespread body pain, fatigue, poor sleep and depression. The FDA has approved three drugs to treat fibromyalgia -- duloxetine (Cymbalta), milnacipran (Savella) and pregabalin (Lyrica) -- but many patients say the drugs are ineffective and often have side effects.  

Previous studies have suggested that weight loss can help lower pain levels, but the improvement was thought to be caused by reduced stress on knees, hips and lower back – parts of the body that are weight-bearing.  

The new study suggests that a strict diet alone can significantly reduce fibromyalgia pain without major weight loss, but researchers caution that more studies are needed to fully understand the biological processes at work.

“The implications of this study suggest an early association between caloric restriction, through a VLED, and fibromyalgia symptoms. Although a larger study with a control group would be the next step in investigating this association, this provides important information for clinicians who counsel patients on alternatives to pharmacologic treatments for pain and other somatic symptoms,” researchers concluded.     

Many previous studies have shown that a low calorie diet can help reduce pain levels. A 2018 study at the University of Michigan found that obese patients on a low-calorie liquid diet for 12 weeks not only had lower pain levels in their knees and hips, but also in unexpected areas such as the abdomen, arm, chest and jaw. Study participants who lost 10% of their weight also reported better mental health, improved cognition and more energy.

Misogyny in Medicine Harms Fibromyalgia Patients

By Dr. Denise Phan, Guest Columnist

Anyone who has practiced medicine or been involved in women's health in the past 50 years has encountered fibromyalgia in one form or another. Many of us have seen the fibromyalgia pendulum swing from under-recognition to over-diagnosed, and back to under-diagnosed again.

Although the course of fibromyalgia mirrors our society's recognition and treatment of pain in general, this particular disorder is also handicapped by its association with women. Since women were not part of the medical and research establishment until recently, diseases that affect women exclusively or predominantly have often been ignored or downplayed. 

Admittedly, fibromyalgia is not an easy diagnosis to make and has no reliable treatments. It is also not progressive, does not cause permanent muscle or joint damage, and does not directly cause early death. Until recently, there were no easy blood markers for fibromyalgia as with other rheumatologic diseases. No x-rays or MRI findings can help diagnose it. 

But the main problem with fibromyalgia was that the vast majority of patients who present with this syndrome of widespread pain and tender points are women.

Thus, it was easier for the arrogant and sexist wing of medicine to relegate fibromyalgia to the "histrionic" or "psychogenic" disorders that predominantly affect women. 

DR. DENISE PHAN

Other examples of severe disabling painful conditions that affect women more than men are endometriosis, pelvic pain, polymyalgia rheumatica, migraine, lupus, scleroderma, and trigeminal neuralgia. Some of these disorders are just now being recognized, researched and beginning to get treated. 

Though the term fibromyalgia was first coined in the 1970s, the disease can be traced back thousands of years to biblical times. When I was going through medical school and residency training in the 1980s, many of my attending physicians refused to recognize fibromyalgia as a "real" disorder and often did not offer any treatment for it. 

To some degree, this was due to our poor understanding of how the nervous system affects musculoskeletal tissue. But in the vast majority of cases, the refusal to acknowledge fibromyalgia stemmed from the undercurrent of misogyny that permeates medicine even today. 

Learning How to Treat Fibromyalgia

There were others in the medical community who recognized fibromyalgia and taught me what it was, how to diagnose it, and how to treat it -- despite our very limited, almost non-existent treatment options at the time.

In the 1990s, when I started my private practice in California’s San Fernando Valley, my practical education of fibromyalgia was furthered by the multiple women who presented in my office with this puzzling, intractable disease. Since there were no FDA-approved treatments yet, we would try every and any off-label treatment possible to see if we can get any long-term or even short-term relief of symptoms. 

There were the traditional trials of NSAIDs, tricyclics like amitriptyline, trazodone, SSRI's, low dose opioids, muscle relaxants, warm water physical therapy, trigger point injections; and then the non-traditional treatments like guaifenesin, anti-inflammatory diets, acupuncture, yoga, tai-chi, sauna, infrared therapy, cannabis, low dose naltrexone and moving to a warm, dry climate. 

Although none of these treatments are highly effective; when they did work it was a tremendous relief to restore function to these long-suffering patients. Despite this, I would still occasionally learn of suicide threats and attempts by fibromyalgia patients who did not respond to any of these treatments. 

These patients pushed me and other doctors to treat pain seriously; so that it does not become a cause of other morbid pathologies such as depression, fibro fog, cervicogenic headache, irritable bowel, overactive bladder and chronic fatigue. It also emboldened us to use stronger opioids, if necessary, to control chronic pain. This coincided with the release of longer-acting opioids like MS Contin, fentanyl patches and OxyContin. 

As the recognition of fibromyalgia went mainstream in the 2000s, so did the push to control pain more aggressively with higher doses of opiates. Laws were passed and guidelines were published, urging physicians to treat pain seriously. Physicians were taught, in one seminar after the other, that longer-acting opioids would control pain throughout the day with less need for pill-popping. This would provide more stable blood levels and less euphoria, making opioids less habit-forming and minimize addiction potential. 

In the late 2000s, Lyrica was the first medication specifically approved for the treatment of fibromyalgia, followed in quick succession by Savella and Cymbalta. Fibromyalgia patients benefited from the increased recognition and treatment of their disorder and the aggressive approach to pain control. 

Many of my patients who didn't respond to off-label treatments achieved remission with the new FDA-approved meds. Some who didn't were eventually stabilized on higher doses of hydrocodone, oxycodone, Dilaudid, methadone, buprenorphine, morphine or fentanyl. Some of the more severe cases were able to get off oral meds and restore normal daily function after we implanted subcutaneous pain medicine pumps. 

A New Betrayal

Then in the early 2010s, reports of rising death tolls from opiate overdoses began coming in, often involving drug seekers who were crushing and snorting OxyContin tablets to get high. It was also recognized that patients on chronic opioids were at risk of accidental overdose.

In response, more cautious opioid prescribing guidelines came out from state medical boards and the CDC; followed by the DEA prosecuting pharmacies and pain management doctors. One pain clinic after another started closing down, their patients were often red-flagged and unable to find new doctors. Vast numbers of patients became collateral damage as the news media and legal profession fanned the flames of the war against opiates. 

For chronic pain patients in general, the lack of access to pain meds required them to make serious adjustments to their lifestyles, like not getting out of bed, not holding a job, and not taking care of their family. For many fibromyalgia patients, it was as if the doors to treatment were slammed shut. 

The latest betrayal for these patients is coming from the medical and academic community itself. I was horrified and shocked at my last pain management seminar when the young professor lecturing on the topic of fibromyalgia stated aloud the official current policy of the medical community is that there is no role for opioids in treating fibromyalgia. 

When asked what we should do for patients who have failed all the recommended treatments, FDA-approved and otherwise, he could only recommend yoga. That was when I realized that misogyny was back in style. The medical community has been cowed by “opiate hunters” into toeing the line and spouting what is essentially a ludicrous theory: the idea that we should not use pain medicine in the treatment of chronic pain. 

This is what is being taught today in medical schools all over the country. The next generation of physicians is being trained to think that it's okay to leave people in chronic pain day after day, when there are good medicines available that, when used judiciously, may be able to restore life and function to an incapacitated patient. 

Obviously, there is the risk of serious side effects from opioids, just as there are for any powerful medications. But that is what we are trained to do, to take into account these side effects for each individual patient, to evaluate the risks versus benefits of each treatment, and to monitor them as best we can. That is what my Hippocratic Oath tells me to do. 

Now, if only we can get through to the other less misogynistic side of the medical community. The ones with enough courage to speak truth to power. There are some of them in medical schools and ivory towers everywhere, who can recognize injustice and who will speak common sense to our future doctors.

Widespread Pain Raises Risk of Dementia and Stroke

By Pat Anson, PNN Editor

Widespread body pain caused by fibromyalgia and other chronic pain conditions raises the risk of stroke and dementia, including Alzheimer’s disease, according to a new study.

Researchers looked at health data for nearly 2,500 second generation participants in the long-running, community-based Framingham Heart Study. Participants in the “offspring” phase of the study were given a comprehensive check-up that included a physical exam, lab tests and detailed pain assessment when they enrolled in the early 1990’s. They were then reassessed every four years for signs of cognitive decline, dementia or stroke.

Over the next two decades, 188 of the participants were diagnosed with some form of dementia and 139 had a stroke.

While the number of cases was small, researchers found an association between pain and cognitive decline. Participants with widespread pain were 43% more likely to have some type of dementia, 47% more likely to have Alzheimer’s disease, and 29% more likely to have a stroke compared to those without widespread pain (WSP). 

“These findings provide convincing evidence that WSP may be a risk factor for all-cause dementia, AD dementia (Alzheimer’s), and stroke,” researchers concluded. “While it is known that chronic pain or persistent pain without detailed classification is associated with poorer cognitive performance in cross-sectional or cohort studies, our study was based on much more accurate assessments for pain at a longitudinal population level. The specific presence of WSP… has long-term implications for dementia and AD.”

The researchers said there were three possible explanations for the link between pain and cognitive decline. First are lifestyle factors associated with pain, such as reduced physical activity, poor diet, alcohol and weight gain. Second is that stress caused by widespread pain may impair cognitive function; and third is that WSP may be a “preclinical phase” of dementia and AD.

Previous studies have also linked chronic pain to dementia. A large 2017 study found that older people with chronic pain experience faster declines in memory and are more likely to develop dementia. A more recent study suggests that people with chronic pain are at higher risk of memory loss and cognitive decline if they have lower levels of education, income and access to healthcare.

Antidepressants, anti-psychotics, antihistamines and other common medications may also cause confusion and disorientation that is mistaken for dementia, especially in older adults. When patients are taken off the drugs, their cognitive function may improve.  

Previous studies have also linked widespread pain to cancer, peripheral arterial disease, cardiovascular disease and increased mortality.

Study of Fibromyalgia Drug Continues Despite Disappointing Results

By Pat Anson, PNN Editor

New Jersey-based Tonix Pharmaceuticals says it will proceed with a Phase 3 study of a drug to treat fibromyalgia, despite disappointing results that caused the company to stop enrolling new patients.

Based on an interim analysis of the first 337 participants enrolled in the RALLY study, an independent data monitoring committee found that TNX-102 SL was unlikely to demonstrate a statistically significant improvement in pain compared to placebo. No issues were reported on the safety of the drug.

The finding of the monitoring committee is somewhat surprising, because Tonix recently reported results from another Phase 3 study, which found that TNX-102 SL significantly reduced pain compared to placebo and also improved sleep, fatigue and function in fibromyalgia patients.

“We are surprised and disappointed that the interim analysis did not support continued enrollment in this Phase 3 RALLY study, especially considering the previous Phase 3 RELIEF study, which had a similar design and achieved statistical significance on the primary endpoint,” said Seth Lederman, MD, President and CEO of Tonix. “These results underscore the difficulty in managing and treating fibromyalgia.”

Lederman said the company would continue its Phase 3 trial with the patients who are already enrolled and report the results in the fourth quarter of 2021. It will then determine its next steps.

TNX-102 SL is a sublingual tablet formulation of cyclobenzaprine hydrochloride, a muscle relaxant and anti-depressant that’s being evaluated as a daily bedtime treatment for fibromyalgia. The goal is to see if TNX-102 SL helps fibromyalgia patients sleep better.  In addition to fibromyalgia, TNX-102 SL is also being considered as a treatment for post-traumatic stress disorder (PTSD), alcohol use disorder and agitation in Alzheimer’s disease.

Fibromyalgia is a poorly understood disorder characterized by widespread body pain, fatigue, poor sleep and depression. The National Institutes of Health estimates about 5 million Americans have fibromyalgia. Most people diagnosed with fibromyalgia are women, although men and children can also be affected.

The FDA has approved only three drugs to treat fibromyalgia; the antidepressants duloxetine (Cymbalta) and milnacipran (Savella), and the anti-seizure medication pregabalin (Lyrica). Many fibromyalgia patients say the drugs are ineffective and have unwelcome side effects. A recent analysis found little evidence to support the long-term use of any medication or therapy to treat fibromyalgia.

Chronic Pain Runs in My Family

By Victoria Reed, PNN Columnist

While I was growing up, I knew my mother used a lot of over-the-counter pain relievers. At the time, I didn’t think much of it. As a child, I didn’t view my mother as sick, especially since she rarely went to doctors.

I knew she had a history of major back surgery, and besides being frequently tired and living with sore muscles and a lack of sleep, she seemed to just carry on without the help of doctors.

Now as I look back and take a closer look into the past, I believe my mother suffered from the same or similar chronic pain conditions as I do: degenerative disk disease, fibromyalgia and possibly rheumatoid arthritis.

Two of my sisters also suffer from degenerative disk disease, fibromyalgia, RA and lupus. My brother had severe scoliosis and longstanding chronic back pain. He lived most of his life in pain and died at a relatively young age. In addition, a maternal aunt had chronic pain from multiple sclerosis and eventually died from the disease.

I often wondered if there was anything I did to earn my many diagnoses, but knowing my family’s history has answered that question for me. Studies show that some chronic pain conditions and autoimmune conditions do, indeed, have a genetic origin. This genetic predisposition can be activated by something in the environment, such as a virus, and subsequently could trigger the onset of an illness.

When one of my sons was 6-years old, a respiratory virus caused his immune system to attack his kidneys, resulting in renal failure. He had glomerulonephritis, a condition where the kidneys’ filters become inflamed and scarred. The result is that waste products build up in the blood and body. He had only 15% of his kidney function remaining at the time of diagnosis.

Unfortunately, my son received three misdiagnoses in the two weeks prior to receiving the correct one! Being a fierce advocate for him and knowing with a mother’s intuition that something was seriously wrong, I pushed for doctors to not dismiss his symptoms and look deeper for the problem, as he had begun to swell up. Without proper treatment, he could have ended up on dialysis, the kidney transplant list or suffered from chronic kidney disease for the rest of his life.

Fortunately, after finally getting an accurate diagnosis and quality in-patient supportive care, he began to recover. Today he is a healthy, active 19-year-old with no residual kidney problems.

My 16-year-old daughter has also been diagnosed with fibromyalgia. She suffers from muscle pain, soreness and severe fatigue. I have seen doctors unwilling to take her complaints seriously and unwilling to treat her with anything.

Furthermore, one of my sons also has scoliosis, and having seen what my brother experienced, his future concerns me as well. Many people with scoliosis suffer from back pain throughout their lives.

I am concerned about what my children’s futures may look like, in light of the difficulties that many chronic pain patients face today. As a mom, I will continue to advocate for my daughter’s care and encourage her to advocate for herself as she grows up. It is my hope that compassion and willingness to treat patients properly will return to the specialty of pain management. Parents should not have to fear that their children will be allowed to suffer.

I’m sure that my family is not unique. Families with multiple chronic pain conditions should rally together for support, understanding and most importantly, adequate pain care!

My sisters and I often compare notes and discuss our various treatments. We support each other through our toughest days, and just having that emotional support from each other makes a world of difference. However, many in our chronic pain community do not have that kind of support and are either not believed or taken seriously. Support groups can be very useful in these situations, and I have found that they are helpful. Being a part of a support group assures me that I am not alone in my struggles.

I encourage anyone who feels alone to reach out to someone or join a support group. With social media, it’s now easier than ever to be connected with people when there is no family support.
