Advocacy Group Seeks to Expand Insurance Coverage of Ketamine

By Pat Anson, PNN Editor

A coalition of patients and healthcare providers is launching an effort to expand insurance coverage for ketamine, a non-opioid anesthetic increasingly used to treat chronic pain, depression and post-traumatic stress disorder (PTSD).

Ketamine is typically administered by infusion under strict medical supervision, a process that that can take up to an hour and cost thousands of dollars. The first goal of the Ketamine Taskforce is to get ketamine infusions fully covered by Medicare.

“Medicare doesn’t officially pay for ketamine infusions. What they will pay for is a generic infusion code similar to if someone was getting an antibiotic infused. The level of reimbursement is very low,” says Kimberley Juroviesky, a retired nurse practitioner and task force co-chair who receives ketamine infusions for Complex Regional Pain Syndrome (CRPS). 

“Since these reimbursement rates are so low, the majority of small ketamine clinics don’t accept insurance. This leaves the majority of pain patients without the pain relief they could otherwise be benefiting from.”

Ketamine is approved by the Food and Drug Administration as a surgical anesthetic, but a growing number of ketamine clinics provide off-label infusions for depression, PTSD and difficult chronic pain conditions such as CRPS. The infusions put patients into a hypnotic, dream-like state — leaving them with less physical and emotional pain once the ketamine wears off. Many insurers consider this off-label use experimental.

“If we could get Medicare to officially put ketamine on their schedule as a treatment for chronic pain, this would hopefully raise reimbursement rates to a level where all providers could afford it. Also, this would force private insurers to pay for ketamine infusions as well and no longer refuse to pay saying it’s experimental,” Juroviesky said in an email. 

PNN columnists Barby Ingle and Madora Pennington have both had ketamine infusions, Barby for CRPS and Madora while recovering from foot surgery.

“The swelling in my foot dramatically improved. Chronic, low-grade discomfort along my spine also disappeared. I felt emotional relief from past trauma, from pain and other life experiences,” Madora explained.

“I went into the hospital in a wheelchair, but walked out on my own a week later,” said Barby, after seven days of ketamine infusions. She now gets “booster” infusions four times a year and no longer takes daily pain medication.

Some ketamine users report lingering side effects, such as hallucinations and visual disturbances. Guidelines from the American Society of Anesthesiologists, American Society of Regional Anesthesia and Pain Medicine, and the American Academy of Pain Medicine only support ketamine infusions for CRPS and short-term acute pain.

“Excluding CRPS, there was no evidence supporting ketamine infusions for intermediate or long-term improvements in pain," the guidelines warn.

The Ketamine Taskforce is working with a consortium of ketamine clinics, collecting data on the safety and efficacy of infusions. That research will be shared with the Centers for Medicare and Medicaid Services (CMS) in an effort to expand Medicare coverage of ketamine for pain and mental health conditions.

Pilot Study Launched of Ketamine Tablet as Pain Reliever

By Pat Anson, PNN Editor

Ketamine has become a trendy alternative treatment for pain, depression, anxiety and post-traumatic stress syndrome (PTSD). But to get it, you’ll need to get a ketamine infusion, injection or nasal spray – usually under strict medical supervision.

But someday you may be able to take a ketamine tablet at home, just like you would most other medications. A pilot study is underway at a New York City hospital to see if an oral formulation of ketamine and aspirin could be a useful treatment for pain.

“For certain patients, ketamine could be a real game changer,” says Dr. Joseph Habboushe, an emergency room physician and founder of Vitalis Pharmaceuticals. “If you look at pain management and what we have available to send patients home with, it’s really limited. We have NSAIDs. We have opiates. We have other things that sedate. It’s a fairly limited in choice.”

Ketamine is not an opioid and does not suppress respiration, making it relatively safe to use. But in high doses, it puts patients into a dissociative, dream-like state -- making it inappropriate for outpatient use.

What Habboushe and his colleagues hope to demonstrate is that a low dose of ketamine, when combined with aspirin, can be an effective and non-addictive pain reliever that can be used safely at home.

Their observational study at Maimonides Medical Center will enroll 25 patients with acute musculoskeletal pain, who will receive 0.5 mg of oral ketamine administered simultaneously with 325mg of aspirin. Pain scores and adverse events will be recorded at various intervals for up to two hours.

The study is being led by Sergey Motov, MD, an emergency room physician who is passionate about finding alternatives to opioids.

VITALIS PHARAMCEUTICALS

"The need for safe and efficacious analgesics in the emergency department and on an outpatient basis is stronger than ever," Motov said in a statement. “Taking a novel approach to orally-administered ketamine has the potential to move physicians one step closer to successfully combatting the nation's ongoing opioid crisis.”

Vitalis has developed a proprietary formulation of aspirin -- called VTS-Aspirin -- that delivers faster and stronger pain relief than traditional aspirin. Preliminary research indicates that combining VTS-Aspirin with low-dose ketamine may boost its potency.

“This is a proof-of-concept study. If we can demonstrate that ketamine will work orally, then it can be used for acute pain, maybe later chronic pain, maybe depression and all the other indications,” Habboushe told PNN. “If we can achieve that, it will be a breakthrough that will absolutely drive a lot of value to patients by reducing opiate need and reducing their pain in a very significant way. And so, it’s worth studying.”

Vitalis is also studying the use of VTS-Aspirin with fumaric acid as a treatment for multiple sclerosis that has fewer side effects. Also undergoing research is a combination of VTS-Aspirin with niacin as a treatment for high cholesterol.

Breakthrough Medical Devices to Receive Medicare Coverage

By Pat Anson, PNN Editor

Medical device manufacturers are cheering a decision by the Centers for Medicare & Medicaid Services (CMS) to have Medicare begin covering hundreds of “Breakthrough Devices” certified by the Food and Drug Administration.

The FDA’s Breakthrough Device Program was launched in 2018 to speed up the development of innovative technology for the treatment and diagnosis of life-threatening or debilitating medical conditions such as chronic pain. But FDA approval was then followed by a lengthy and costly review process for Medicare coverage, which delayed patient access to the devices.

The Medicare Coverage of Innovative Technology (MCIT) rule change allows Medicare to begin covering breakthrough devices simultaneous to FDA approval, making them immediately available to over 60 million Medicare beneficiaries. The rule change goes into effect March 15.

“Despite being deemed safe and effective by the FDA, Medicare beneficiaries have not had predictable, immediate access to innovative breakthrough devices,” CMS Administrator Seema Verma said in a statement. “CMS remains committed to transforming the health care delivery system through initiatives like MCIT that focus on results, removing government barriers to advancing innovations, fostering competition, and ensuring quicker access to the most advanced therapies for Medicare beneficiaries while providing them with better value and outcomes.”

The rule change benefits companies like San Francisco-based Bone Health Technologies, which announced last month that its OsteoBoost Vibration Belt had received breakthrough device approval as a treatment for osteopenia, a precursor to osteoporosis.

“We are thrilled by this announcement as it will help us get our potentially life-changing device, affordably into the hands of patients who need it much more quickly,” said Laura Yecies, CEO of Bone Health Technologies. “There is a lack of safe, effective treatments for osteopenia, a condition that effects over 40 million Americans. It is exciting that CMS is supporting the efforts of companies working to solve these important unmet needs."

Another company likely to benefit is AppliedVR, which announced in October that its virtual reality headset had received breakthrough device approval as a treatment for fibromyalgia and chronic intractable low back pain.

“This new rule change means that Medicare recipients in need of pain relief will have access to our novel chronic pain therapy,” said Josh Sackman, co-founder and president of AppliedVR, who believes Medicare reimbursements will help speed up coverage of breakthrough devices by private insurers.  

“The MCIT rule change doesn’t directly impact coverage from commercial payers. They will continue to have their own standards for evidence and require new products to follow the existing evaluation process. However, the mandatory Medicare coverage will accelerate products getting into the market, where real world evidence will be collected on the value of those Breakthrough Devices,” Sackman explained in an email to PNN. 

“This data is extremely valuable for commercial payers to assess coverage. This should have a halo effect with payers that see the benefits of a breakthrough device in their Medicare book of business and may help them choose to expand coverage to their other lines of business, including commercial plans.”

Medicare coverage of a breakthrough device will initially be limited to four years. After the coverage period is over, CMS will reevaluate the devices based on clinical evidence of their effectiveness. Importantly, the four-year window also creates a revenue stream for manufacturers to continue improving their devices or invent new ones.

Skin Patch Reduces Pain Without Use of Drugs

By Pat Anson, PNN Editor

A drug-free skin patch that uses nanotechnology to help dial down pain levels provided significant relief to people living with arthritis, neuropathy and musculoskeletal pain, according to the results of a small study.

The Kailo pain patch contains billions of tiny nanoparticles made with copper, silver and silicon that help transmit electromagnetic signals from the nervous system. In theory, the nanoparticles act as a “bridge” over inflamed nerve pathways and restore their ability to transmit pain signals properly.

The patch is made by Utah-based Pain Relief Technologies, which claims in marketing material that its patented technology provides “natural relief anywhere on your body, in seconds.”

In the study, 66 patients wore the Kailo patch while continuing to take oral analgesic medications such as opioids and non-steroidal anti-inflammatory drugs (NSAIDs).

After 30 days, self-reported pain levels dropped significantly and 98 percent of patients said they reduced or stopped using oral medication. Their mood, sleep, walking ability, and other quality of life measures also improved.

The study findings, published in the journal Anesthesia and Pain Research, suggest that the analgesic effects of the Kailo patch are long lasting. About one in every four patients said their pain did not return after the patch was removed. Over half said it took at least a day for the pain to resume.

CLARITY SCIENCE IMAGE

“Modern science has allowed the incorporation of nanotechnology into topical patch systems, minimizing, and in the case of Kailo, eliminating the need for drugs/pharmacological agents. The interim results of this study are incredibly positive, and we look forward to providing the next phase of data that we have collected from patients with mild, moderate or severe pain,” lead investigator Jeffrey Gudin, MD, said in a statement.

Gudin was compensated by Clarity Science for conducting the study. You may recognize him from TV commercials for SalonPas, a rival pain relief patch.

An anesthesiologist by training, Gudin has become a prolific researcher, consultant and public speaker for dozens of companies involved in pain management, including Purdue Pharma, Salix, BioDelivery Sciences and Quest Diagnostics. He’s been paid over $1.5 million for his services since 2013, according to the OpenPayments database. In an email to PNN, Gudin said most of the money has been used for research and consulting on new analgesic therapies.

The Kailo patch is reusable and can be purchased without a prescription for $119. Reviews on Amazon for Kailo are mixed.

“Immediately upon placing it on my low back I could feel a warmth and my pain decreased rapidly. I was able to go to work the next day with relative comfort,” wrote one buyer who suffered pain from a hamstring injury.

“Did not reduce pain actually increased pain level,” said a disappointed user.

“Nothing else has worked for me but this significantly reduced my pain. It does not completely remove the pain, so don't expect that. But it reduced it enough that I can play with my kids, mow the lawn, work, essentially be a normal human being without medication,” said another user.

“I used it for a week, received no relief whatsoever,” wrote another buyer. “I am very dissatisfied and would like my money back.”

Topical Gel Shows Promise as Treatment for Neuropathic Pain

By Pat Anson, PNN Editor

An experimental gel developed to prevent skin damage caused by aging and ultraviolet light is showing promise as a treatment for chronic neuropathic pain, according to research underway in Australia.

The topical gel – known as RM191A – contains a copper-based compound that is absorbed by the skin and prevents the buildup of free radicals that cause skin damage associated with aging and skin cancer.

In a study recently published in the journal Redox Biology, RM191A was found to have potent antioxidant, anti-inflammatory and wound-healing properties in laboratory mice.

The gel is currently being evaluated in 24 patients at a Sydney hospital as a treatment for chronic nerve pain caused by surgery, chemotherapy, trauma and diabetes.  Results are expected later this month.

“Early sample uses of this topical formulation indicated it could be a significant in the management of certain types of chronic nerve pain,” says Llewellyn Casbolt, chief scientist and co-founder of Sydney-based RR MedSciences, which is developing the gel.

“In many ways, scientists see our discovery as a new class of anti-inflammatory that acts by the modulation of free radicals as well as reducing several inflammatory cytokines, providing a drug that can be therapeutically useful where the reduction of inflammation, as well as cellular and tissue healing - indeed pain relief - is also advantageous for a patient.”

The company plans to release an over-the-counter version of its gel in the next 12-18 months as a treatment for skin damage. It will take longer to get regulatory approval for the gel as a treatment for nerve pain and may require a prescription.

RR MedSciences (RRMS) plans to conduct further trials and is seeking additional partners and funding to accelerate the gel’s development.

“The management of pain, often related to conditions of inflammation or trauma that results in nerve or chronic pain is an area of great need.  Advancing the ability for people to modulate their pain, in a safe and effective manner that improves quality of life, is a core objective,” said Helena Libershal Casbolt, CEO and co-founder of RRMS.

A subsidiary of RRMS is currently selling a copper-based body cream called Blue Healer Care as a treatment for damaged skin and for relief from skin irritation and muscle soreness.

Why Water Soaking Works

By Forest Tennant, PNN Columnist

There is no medical treatment older than water soaking. It is legend and still works. Adhesive Arachnoiditis and other Spinal Canal Inflammatory Disorders (SCID’s) are particularly helped by water soaking – so much so that we consider it an essential treatment.

Why water soaking relieves pain has been a mystery until recent times. It is known that damaged or “dead” nerves won’t conduct  the body’s natural electric currents, so electricity backs up and is trapped or retained in body tissues. The result is more inflammation and pain “all over.”

Electricity has a negative charge and water tends to have a positive charge, so it pulls out excess electricity from the body, reducing inflammation and pain. If the water contains a mineral, it will pull out even more electricity. That is why mineral hot baths and Epsom Salts are so effective.

The lumbar-sacral spinal canal is loaded with nerve roots. They constantly conduct electric currents that go from the spinal cord to the legs, feet, bladder, sex organs and intestine.

Any damage, by any cause, to the spinal canal nerve roots causes a backup of electricity which is painful and produces even more inflammation. To prevent disease progression, daily water soaking can be most helpful.

Types of Water Soaking

You don’t have to have a jacuzzi or pool to do water soaking. A bathtub is great, but most of us take showers. When you shower, keep the water as hot as you can stand, and massage and stretch your back muscles as the hot water runs over your back. Soaking for 10 to 15 minutes in a jacuzzi, pool or bathtub is preferable, but hot showers morning and night is about as good.

Don’t forget the Epsom Salts. The body normally excretes its excess electricity into the air, mainly through nerve ends in the hands, head and feet. Foot soaking, particularly with Epsom Salts or other herbal salts, is an age-old remedy that attracts the electric currents that travel down the sciatic and other leg nerves.

Another soaking technique is a warm, water-soaked towel or other wet wrap placed over the lower back for 5-10 minutes. Remember, water soaking isn’t an “all wet” idea.

Exercise Is Best Treatment for Low Back Pain, But Why?

By Pat Anson, PNN Editor

There has long been a consensus that the best way to treat chronic lower back pain (CLBP) – the world’s leading cause of disability – is by staying active and exercising. But a new study by Australian researchers failed to identify precisely why exercise is beneficial.

“A lot of treatments have stemmed from studies for people with CLBP, but the one with the most consistent evidence of benefit is exercise,” says senior author Matt Jones, PhD, an exercise physiologist, clinician and researcher at the UNSW Sydney School of Medical Sciences. “Despite decades of research in the area and more than 100 studies we analysed in our review, we still do not have a good idea of why exercise might be effective for CLBP.”

Jones and his colleagues recently reported their findings in the journal Musculoskeletal Science and Practice. They reviewed 110 research papers on CLBP conducted in Australia, United States, China, Brazil and Europe, and found little agreement on why researchers thought exercise relieved lower back pain.

“Researchers proposed common reasons as to why exercise was beneficial, including improvements in fitness – for example, core stability, aerobic fitness – and improvements in mood and confidence,” Jones said. “But the effects of these proposed reasons on outcomes for people with CLBP were seldom examined in the papers.

“There have been trends in research over time, where everyone focuses on a ‘flavour of the month’ – like motor control or McKenzie therapy, for example – but because the effects of exercise are broad and it impacts on many different systems in the human body, it’s difficult for researchers to pinpoint exactly why they think it might be benefiting people with pain.”

At any given time, over 500 million people worldwide are suffering from CLBP, which is “non-specific” back pain lasting three months or longer – not the severe back pain caused by degenerative disc disease, spinal injuries, arthritis and other chronic conditions. CLBP mostly affects adults of working age in lower socioeconomic groups, who often have physically demanding jobs.

A 2018 review published in The Lancet by an international team of researchers found that CLBP is often treated with bad advice, inappropriate tests, risky surgeries and painkillers. The authors said there was limited evidence to support the use of opioids for low back pain, and epidural steroid injections and acetaminophen (paracetamol) were not recommended at all.

“The majority of cases of low back pain respond to simple physical and psychological therapies that keep people active and enable them to stay at work,” said lead author Professor Rachelle Buchbinder of Monash University in Australia. “Often, however, it is more aggressive treatments of dubious benefit that are promoted and reimbursed.”

Jones said the aggressive treatments may not work because they don’t address underlying psychological reasons for back pain.

“Chronic pain is tricky and there are a lot of factors that can contribute to it – so, it's not simply biological aspects of tissue damage, but there are psychosocial elements at play, as well things like a person’s mood or confidence in their own abilities to do something,” he said. “Today’s evidence suggests CLBP likely comes from the brain and nervous system being a bit over-protective and generating a pain response – despite no obvious physical damage to the body.”

Although his review did not address what specific exercises were most effective for CLBP, Jones and his team recommended 33 “mechanisms” that people can use to relieve back pain, such as building muscle strength and flexibility or through social support and coping strategies.

“Many scientists have investigated this question before and the short answer is, there are no specific exercises recommended to alleviate CLBP,” he said. “But there are literally hundreds of studies on exercise for people with chronic pain, not only CLBP, and researchers consistently find exercise is one of the most effective treatments – it might not cause huge reductions in pain and disability, but it does help.”

Vibrating Belt Gets FDA ‘Breakthrough Device’ Designation for Osteoporosis

By Pat Anson, PNN Editor

The U.S. Food and Drug Administration has given “Breakthrough Device” designation to a vibrating belt that lowers the risk of bone fractures caused by osteoporosis. When worn around the waist, the OsteoBoost Vibration Belt delivers gentle stimulation to the hips and spine, simulating the effects of exercise and strengthening bones.

Osteoporosis is caused by the loss of bone mineral density (BMD) and is one of the most common health conditions associated with old age. More than 10 million Americans suffer from osteoporosis and 43 million have its precursor, osteopenia.

About 1 in 2 women and 1 in 4 men over the age of 50 will suffer an osteoporosis-related fracture, usually in their hip or spine. Breaking a bone is especially traumatic for the elderly and can lead to a cascade of health problems, including chronic pain, disability and early death.

Osteoporosis is currently treated with changes in diet, exercise and bisphosphonate drugs such as Fosamax, which slow the loss of BMD. However, long term use of bisphosphonates can lead to side effects such as bone, muscle or joint pain, as well as nausea and heartburn.

“For years, I have wanted a better option for my patients with low bone density that doesn’t have the potential side effects and the inconvenience of current drug treatments. With OsteoBoost we’ve created a safe, drug-free alternative that is easy and convenient. Now my patients with osteopenia have a new way to improve their bone health and reduce their risk of fracture,” says Dr. Shane Mangrum, co-founder of San Francisco-based Bone Health Technologies, which makes the OsteoBoost belt.

OsteoBoost uses whole body vibration (WBV) technology originally developed for NASA to improve the bone health of astronauts in a weightless environment. Here on earth, WBV has been found to improve bone mineral density, but it requires users to stand on a stationary vibrating platform, which isn’t always practical.

Because OsteoBoost is wearable, users can go for a walk or perform simple household chores while getting treatment. It’s recommended the device be used in 30-minute sessions, 3 to 5 times a week.

In a small clinical trial, OsteoBoost reduced bone loss in postmenopausal women by an average of 14%, a reduction similar to bisphosphonates. The National Institutes of Health is funding a larger, $2 million study of OsteoBoost that is currently enrolling postmenopausal patients. It is scheduled to be completed in early 2022.

If that study is successful, the FDA’s Breakthrough Device designation will speed up the agency’s review of OsteoBoost and help bring it to market sooner. The belt is not currently available for purchase and will require a a prescription when it is.

A 2011 Canadian study found that WBV did not improve bone mineral density in postmenopausal women who used a vibrating platform daily for a year while also taking vitamin D and calcium supplements.

"Although commercially available WBV devices are marketed to and used by patients, the beneficial effects of WBV on fracture risk and BMD have not been established, and recent randomized, controlled trials in postmenopausal women have shown conflicting results," said lead researcher Angela Cheung, MD, at University Health Network in Toronto. "Women would be farther ahead in making sure that they are exercising regularly and eating nutritious foods."

Music and ‘Positive Suggestions’ Reduce Need for Opioids in Surgery Patients

By Pat Anson, PNN Editor

Studies have shown that long term opioid use and addiction are rare in patients given opioids for pain control during and after surgery.  Nevertheless, many hospitals are adopting policies that reduce or eliminate the use of opioids for postoperative pain; opting instead for non-opioid pain relievers such as acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs).

A new placebo-controlled study suggests that relaxing music and comforting words played during surgery might also be a substitute for opioids in some patients.  

Researchers at five German hospitals recruited 400 patients scheduled for elective surgery lasting 1 to 3 hours. While under general anesthesia and unconscious, half the patients listened through earphones to a tape that played soothing background music and “positive suggestions” for 20 minutes. The tape played repeatedly until surgery ended. The other patients were assigned to a blank tape and served as a control group.     

Researchers found that patients in the music group had lower pain scores and required lower opioid doses – about 2.8 MME less per patient -- in the first 24 hours after surgery. Over a third (37%) did not need opioids at all, compared to 26% in the control group.

“This study found a statistically significant reduction in use of postoperative opioids in patients who received therapeutic suggestions by audiotape during surgery, which comprised background music and mindful text. Furthermore, the number of patients who requested and received opioids was significantly lower after the intervention,” researchers reported in the British Medical Journal.

“A mean saving of 2.8 MME for each patient might seem unimportant; however, in most pain studies the focus is generally on relative saving and not the absolute dose, and an opioid dose reduction of 30%, as reported here, is considered relevant.”

In addition to less pain and need for analgesics, patients in the music group also had less nausea and recovered faster from surgery.

Connected Consciousness

The study findings also suggest that – even under general anesthesia – patients can still hear and process words subconsciously. This “connected consciousness” runs against long-held beliefs that patients under anesthesia don’t have thoughts and feelings. In an editorial, one researcher called this finding “astonishing.”

“Usually there is no reaction to auditory or other stimuli, including surgery, expected or observed in patients under general anaesthesia,” wrote corresponding author Ernil Hansen, MD, a professor of Anesthesiology at the University Hospital of Regensburg, Germany.

“This knowledge and appreciation of intraoperative perception should lead us to more thoughtful behaviour in the operating theatre, for example, what noise levels or potentially unnecessary conversations are we exposing patients to, and to consider a wide use of therapeutic communication as a feasible, non-drug support of medical interventions and an integral part of therapy and care.”

This isn’t the first study to find that music can be a useful tool to reduce pain and anxiety.

Mozart’s “Sonata for Two Pianos” has been found to be helpful in treating patients with epilepsy. And a 2006 study found that listening to music for an hour each day helped reduce pain, depression and disability in patients with chronic non-cancer pain.

Tarantulas May Help Develop New Pain Medication

By Pat Anson, PNN Editor

Venom from a bird-catching Chinese tarantula may hold the key to medications that could someday block pain signals in humans, according to a new study at the University of Washington School of Medicine. Researchers say the oversized, hairy spiders inject a toxin into the birds that quickly immobilize them.

"The action of the toxin has to be immediate because the tarantula has to immobilize its prey before it takes off," said William Catterall, PhD, a professor of pharmacology and lead author of a study published in the journal Molecular Cell.

Catterall and his colleagues were curious how the venom works, so they used a high-resolution cryo-electron microscope to get a clear molecular view of its effect on nerve cells.

They found that tarantula venom contains a neurotoxin that locks the voltage sensors on sodium channels, the tiny pores on cell membranes that generate electric signals to nerves and muscles.

Locked in a resting position, the voltage sensors are unable to activate and the spider’s prey is essentially paralyzed.

"Remarkably, the toxin plunges a 'stinger' lysine residue into a cluster of negative charges in the voltage sensor to lock it in place and prevent its function," Catterall said. "Related toxins from a wide range of spiders and other arthropod species use this molecular mechanism to immobilize and kill their prey."

In humans, sodium channels known as the Nav1.7 channel are essential for the transmission of pain signals from the peripheral nervous system to the spinal cord and brain.

UNIVERSITY OF WASHINGTON

In theory at least, drugs modeled after tarantula venom could be used to target and immobilize the Nav1.7 channel. Previous research has shown that people born without Nav1.7 channels due to genetic mutation are indifferent to pain – so blocking those channels in people with normal pain pathways could form the basis for a new type of analgesic.

"Our structure of this potent tarantula toxin trapping the voltage sensor of Nav1.7 in the resting state provides a molecular template for future structure-based drug design of next-generation pain therapeutics that would block function of Nav1.7 sodium channels," Catterall explained.

While venom-based medicine may sound impractical and more than a little creepy, it’s not unheard of. A pharmaceutical drug derived from cone snail venom is already being used to treat chronic pain. Prialt is injected into spinal fluid to treat severe pain caused by failed back surgery, trauma, AIDS and cancer. Like tarantula venom, Prialt blocks channels in the spinal cord from transmitting pain signals to the brain.

Can ‘Magic Mushrooms’ Help Dying Patients?

By JoNel Aleccia, Kaiser Health News

Back in March, just as anxiety over COVID-19 began spreading across the U.S., Erinn Baldeschwiler of La Conner, Washington, found herself facing her own private dread.

Just 48 and the mother of two teenagers, Baldeschwiler was diagnosed with stage 4 metastatic breast cancer after discovering a small lump on her chest, no bigger than a pea.

Within weeks, it was the size of a golf ball, angry and red. Doctors gave her two years to live.

“It’s heartbreaking,” she said. “Frankly, I was terrified.”

But instead of retreating into her illness, Baldeschwiler is pouring energy into a new effort to help dying patients gain legal access to psilocybin — the mind-altering compound found in so-called magic mushrooms — to ease their physical and psychic pain.

“I have personally struggled with depression, anxiety, anger,” Baldeschwiler said. “This therapy is designed to really dive in and release these negative fears and shadows.”

Dr. Sunil Aggarwal, a Seattle palliative care physician, and Kathryn Tucker, a lawyer who advocates on behalf of terminally ill patients and chairs a psychedelic practice group at Emerge Law Group, are championing a novel strategy that would make psilocybin available using state and federal “right-to-try” laws that allow terminally ill patients access to investigational drugs.

They contend that psilocybin — whether found in psychedelic mushrooms or synthetic copies — meets the criteria for use laid out by more than 40 states and the 2017 Right to Try Act approved by the Trump administration.

“Can you look at the statute and see by its terms that it applies to psilocybin?” Tucker said. “I think the answer is yes.”

Currently, psilocybin use is illegal under federal law, classified as a Schedule 1 drug under the U.S. Controlled Substances Act, which applies to chemicals and substances with no accepted medical use and a high potential for abuse, such as heroin and LSD.

Recently, however, several U.S. cities and states have voted to decriminalize possession of small amounts of psilocybin. This month, Oregon became the first state to legalize psilocybin for regulated use in treating intractable mental health problems. The first patients will have access beginning in January 2023.

It’s part of a wider movement to rekindle acceptance of psilocybin, which was among psychedelic drugs vilified — and ultimately banned — after the legendary counterculture excesses of the 1960s and 1970s.

“I think a lot of those demons, those fears, have been metabolized in the 50 years since then,” Aggarwal said. “Not completely, but we’ve moved it along so that it’s safe to try again.”

He points to a growing body of evidence that finds that psilocybin can have significant and lasting effects on psychological distress. The Johns Hopkins Center for Psychedelic and Consciousness Research, launched this year, has published dozens of peer-reviewed studies confirming that psilocybin helped patients grappling with major depressive disorder and suicidal thoughts.

Researchers are also looking at psilocybin as a treatment for post-traumatic stress disorder (PTSD), Lyme disease syndrome, cluster headaches and migraines. A small placebo-controlled study by Yale researchers found that migraine sufferers experienced a significant decrease in weekly migraine days after only one dose of psilocybin. 

“Psilocybin was well-tolerated; there were no unexpected or serious adverse events or withdrawals due to adverse events. This exploratory study suggests there is an enduring therapeutic effect in migraine headache after a single administration of psilocybin,” researchers found. 

Psilocybin Shifts Perception

Psilocybin therapy appears to work by chemically altering brain function in a way that temporarily affects a person’s ego, or sense of self. In essence, it plays on the out-of-body experiences made famous in portrayals of America’s psychedelic ’60s.

“What psychedelics do is foster a frame shift from feeling helpless and hopeless and that life is not worth living to seeing that we are connected to other people and we are connected to a universe that has inherent connection,” said Dr. Ira Byock, a palliative care specialist and medical officer for the Institute for Human Caring at Providence St. Joseph Health.

“Along with that shift in perspective, there is very commonly a notable dissolution of the fear of dying, of nonexistence and of loss, and that’s just remarkable.”

The key is to offer the drugs under controlled conditions, in a quiet room supervised by a trained guide, Byock said. “It turned out they are exceedingly safe when used in a carefully screened, carefully guided situation with trained therapists,” he said. “Almost the opposite is true when used in an unprepared, unscreened population.”

The FDA has granted “breakthrough therapy” status to psilocybin for use in U.S. clinical trials conducted by Compass Pathways, a psychedelic research group in Britain, and by the Usona Institute, a nonprofit medical research group in Wisconsin. More than three dozen trials are recruiting participants or completed, federal records show.

But access to the drug remains a hurdle. Though psychedelic mushrooms grow wild in the Pacific Northwest and underground sources of the drug are available, finding a legal supply is nearly impossible.

End of Life Washington, a group focused on helping terminally ill patients use the state’s Death With Dignity Act, recently published a policy that supports psilocybin therapy as a form of palliative care. Other treatments for anxiety and depression, such as medication and counseling, may simply not be practical or effective at that point, said Judith Gordon, a psychologist and member of the group’s board of directors.

“When people are dying, they don’t have the time or the energy to do a lot of psychotherapy,” she said.

Baldeschwiler agrees. With perhaps less than two years to live, she wants access to any tool that can ease her pain. Immunotherapy has helped with the physical symptoms, dramatically shrinking the size of the tumor on her chest. Harder to treat has been the gnawing anxiety that she won’t see her 16-year-old daughter, Shea McGinnis, and 13-year-old son, Gibson McGinnis, become adults.

“They are beautiful children, good spirits,” she said. “To know I might not be around for them sucks. It’s really hard.”

Low-Dose Naltrexone Gaining Recognition as Chronic Pain Treatment

By Pat Anson, PNN Editor

Low-dose naltrexone (LDN) is finally getting some recognition from the medical community as a treatment for chronic pain. The December edition of the Journal of the American Dental Association (JADA) features a cover story on the use of LDN by dentists – not to manage short term pain during dental procedures – but to treat chronic oral and facial pain conditions such as temporomandibular joint disorder (TMJ).

“Low-dose naltrexone provides an alternative in medical management of chronic pain disorders as a novel anti-inflammatory and immunomodulator. It can offer additional management options, as orofacial pain conditions share characteristics with other chronic pain disorders,” wrote Elizabeth Hatfield, DDS, corresponding author and clinical lecturer at the University of Michigan School of Dentistry.  

Few mainstream medical organizations have recognized the benefits of naltrexone as a pain reliever, largely because the drug 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 a wide variety of pain conditions have found LDN to be a surprisingly effective pain reliever. PNN columnists have shared their positive experiences using LDN to treat everything from interstitial cystitis to Ehlers-Danlos syndrome to fibromyalgia.  

How naltrexone works is not exactly clear – more research is needed – but LDN supporters believe the drug helps modulate the immune system, reducing inflammation and stimulating the production of endorphins, the body's natural painkiller.  

The lack of good quality research on LDN is evident in the JADA article. Hatfield and her colleagues reviewed nearly 800 studies, but could find only eight that met their criteria for evaluation, most of them focused on treating fibromyalgia. Nevertheless, they say LDN could be an effective and less risky alternative to opioids and non-steroidal anti-inflammatory drugs (NSAIDs) for treating chronic oral and facial pain.

"The unique antinociceptive properties mediated via glial cell modulation, as opposed to previously identified pathways of opioids and anti-inflammatories such as NSAIDs, is attractive as it bypasses certain side effects and concerns with long-term NSAID and opioid use," said Hatfield. "Further benefits include reduction in reported pain levels and measurable increases in quality of life for patients with chronic pain disorders. Additionally, it offers an option for prescribers managing temporomandibular joint disorders with a centralized pain component.”

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

Because naltrexone is only approved to treat addiction, LDN needs to be prescribed “off-label” for pain. Patients interested in trying LDN 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.

Pilot Study Finds Green Light Therapy Improves Fibromyalgia Symptoms

By Pat Anson, PNN Editor

Fibromyalgia patients exposed to green light therapy had significant improvements in their pain, sleep and quality of life, according to a new pilot study published in the journal Pain Medicine.

The small clinical trial by researchers at the University of Arizona is the first to explore the benefits of green light in treating fibromyalgia symptoms. Previous studies have focused on green light therapy as a treatment for migraine headaches. Green light is believed to have a calming effect on the brain and causes less eye strain.  

Twenty-one adult patients with fibromyalgia being treated at the university’s chronic pain clinic were enrolled in the study. They were exposed to green light-emitting diodes (GLED) for one to two hours daily for 10 weeks. While undergoing treatment, patients were asked to avoid all other sources of light, including computers, smartphones and television, but encouraged to engage in other activities such as reading and listening to music, and to avoid falling asleep.

“To our knowledge, this one-way crossover design efficacy-study clinical trial is the first description of a successful implementation of GLED exposure as a therapy to manage fibromyalgia pain without any reported side effects. The patients enrolled in this study reported significant reduction in their overall average pain intensity, frequency, and duration after GLED treatment,” wrote lead author Mohab Ibrahim, MD, an associate professor in the Departments of Anesthesiology and Pharmacology at UArizona College of Medicine-Tucson. 

In addition to less pain, patients also reported better mood and sleep, and improvements in their ability to work, exercise and perform chores. Eleven patients said they also reduced their use of pain medication, including opioids, while being exposed to green light.    

“GLED may be a safe and affordable method to manage fibromyalgia. We did not observe side effects in animal studies or in reports from our patients. The observed safety and efficacy, coupled with the simplicity of this method, merit further investigation and the design of a randomized clinical trial to fully investigate the role of GLED for fibromyalgia and possibly other chronic pain conditions,” researchers concluded. 

Fibromyalgia is a poorly understood disorder characterized by widespread body pain, fatigue, poor sleep and depression. Many patients report conventional treatments for fibromyalgia are ineffective or have unwelcome side effects. 

In an email to PNN, Ibrahim said he was conducting two more studies on the use of green light to treat other pain conditions, but was not ready to release his findings. He recently reported the results of a small study of green light as a preventative therapy for migraine. 

“Should anyone use green light products? The risk is low, but I still suggest people speak with their physicians first before attempting any therapy,” Ibrahim said.    

Light Sensitivity 

Although more research is needed to fully understand how green light therapy works, some commercial products are available to the public without a prescription.

One is a portable green light lamp made by Allay, a company founded by Harvard Medical School Professor Rami Burstein, PhD, who was the first researcher to discover that different colors in the light spectrum can affect light sensitivity – known as photophobia – among migraine sufferers.

Burstein learned that blue light (the light emitted by TVs and computer screens) can trigger migraines, while a narrow band of green light at low intensity can reduce the severity of migraine attacks.

“Green light has a calming effect because it reduces electrical activity (in the brain),” Burstein told PNN. “It is the only color of light that is associated with positive emotion and reducing anxiety. All other colors of light increase anxiety, irritability, being afraid, being scared, being angry, a whole host of negative emotions.”

Burstein and his partners asked lighting experts to design an affordable green light lamp that people can use at home. Initial estimates ran in the thousands of dollars, but they have since managed to reduce the cost to $150.

“It is safe. It’s not invasive. It is inexpensive,” Burstein says. “Try it. Give it a month or two. If it doesn’t work, you can return it for free. No questions asked.”

Allay began selling the lamps in January with a money back guarantee. Of the 3,000 lamps sold so far, Burstein says less than 4 percent of customers have asked for their money back. He expects an updated version of the lamp to be available by the end of the year for less than $100.

Burstein says the lamp eliminates photophobia in nearly all migraine patients. He recommends that migraine sufferers use the Allay lamp one to two hours every day to reduce the frequency and severity of headaches.

Healthcare Is a Human Right That We Deserve

By Jennifer Kain Kilgore, PNN columnist

I shouldn’t have to write this. But here I am because of headlines like these:

“FTC Refunds Almost $3.9 Million to Purchasers of Deceptively Advertised Quell Wearable Pain-Relief Device”

My body went numb after reading that. The Quell, which I wore for four years, that I blogged about, that I recommended to friends and family? That Quell?

The Federal Trade Commission slapped parent company NeuroMetrix for deceptive advertising. Specifically, the company was cited for claiming the Quell works throughout the whole body and not just where it’s worn.

“NeuroMetrix settled the case – without admitting or denying the allegations – for $4 million. The company also agreed to stop claiming that Quell provides relief for chronic or severe pain beyond the knee area where the device is worn,” PNN reported.

Soon enough I was receiving texts -- “Is this true?” “Does it not work?”

It worked for me, but that’s not why I’m writing this. My testimonial is still and will remain on NeuroMetrix’s website. The company didn’t ask me to come to their defense. Despite the bad press, that gadget worked for me.

NEUROMETRIX IMAGE

Getting a $50 refund from NeuroMetrix in my PayPal account, though? The company’s silence and tacit admission made a helpless rage boil inside where anger has been simmering for weeks and months and years.

It made me as angry as when desperate pain patients called my law office, asking if I would draft legislation or talk sense to their doctors. Or when a genuinely good product came on the market but took advantage of customers. Or when the Sackler family didn’t go to prison after their pharmaceuticals created the conditions for the national opioid epidemic to truly explode. That bubbling anger began to rise.

Where should I direct this rage? At the callers? At the makers of the SpineGym, who took their crowdsourced money and failed to deliver on their promises? At the Sacklers? No, of course not. It’s not about them. My anger is bigger than that.

I shouldn’t have to write a reaction piece about the FTC’s decision. I shouldn’t have to draft laws to change a healthcare system in which pain patients are discounted, dismissed, and even overlooked.  Sometimes our limitations and physical pain prevent us from seeking the help we need.  

I shouldn’t have had to write for Pain News Network in the first place, though I’m thankful for the opportunity to do so. I became a columnist in order to try all the gadgets claiming to cure back and neck pain. If my doctors wouldn’t help me, I would help myself.

And there it is.

A record-breaking number of citizens have already voted. Despite their overwhelming voices, a Supreme Court justice was just appointed whose legal interpretation could dismantle the Affordable Care Act, which is on the Supreme Court Docket on November 10, just seven days after the most important election in history.

If you’re reading this, health insurance is crucially important to you or someone you love. Right now, our president’s legal team is in court attempting to kill the ACA without any kind of replacement during a global pandemic that has killed over 231,000 Americans.

But that’s not why I’m writing this.

I used to blog about my journey through the healthcare system. By the time I’d graduated from the Quell to an implanted spinal cord stimulator (which also works), I’d exhausted myself. It was time to focus on finally, finally healing. You know, being a normal person again.

The spinal cord stimulator -- controversial for sure, and not a surefire bet -- ended up working beyond my wildest dreams. Even though I’ve pulled on wires and scar tissue, my life has been partially restored. My doctor said the Quell was a good indicator as to whether a SCS would even work. If the Quell helped, so would a spinal cord stimulator.  

Before the SCS, I wasn’t able to consistently work as an attorney; I could barely leave my house. I was dependent on my husband for everything from insurance to carrying bags of groceries.

After the SCS, I can do yoga and pilates. I can lift laundry baskets. I can go to work and sit through a two-hour deposition. I can be an actual person again.

But that’s not why I’m writing this.

I shouldn’t have spent sixteen years of my life begging for help. I shouldn’t have to become a patient advocate and a writer for an online publication because I couldn’t otherwise afford pain-relief devices.

I shouldn’t have to write this.

I shouldn’t have to fight my insurance company to get my treatments covered. I shouldn’t have to stagger bill payments to various hospitals so as not to overdraft my account. I shouldn’t be paying for my spinal cord stimulator more than a year after its implantation.

I shouldn’t -- we shouldn’t -- have to do these things. We shouldn’t have to fight so hard to live in what’s supposedly the greatest country on earth.  What’s so great about living in fear? Fear of the unknown, the future, access to healthcare resources, and effective treatments? I’ve lived in fear for long enough, and so have you.

I shouldn’t be here. You shouldn’t be here, reading this. This website shouldn’t exist, and we shouldn’t have to fight so hard. But one in five Americans adults has chronic pain, and something must be done.

Healthcare is a human right, and we deserve it.  So VOTE.  Protect your loved ones by protecting healthcare.
