WHO Releases First Guideline for Chronic Low Back Pain

By Pat Anson, PNN Editor

The World Health Organization (WHO) has released its first-ever guideline for managing chronic low back pain, recommending treatments such as exercise, physical therapy, chiropractic care and non-steroidal anti-inflammatory drugs (NSAIDs).

Chronic low back pain — also known as “non-specific low back pain” — is defined as pain that persists longer than three months, with symptoms that cannot be accounted for by a structural spinal problem or disease process such as arthritis.

Although lower back pain (LBP) is the leading cause of disability worldwide – affecting about 619 million people – there has been little certainty about how to treat it. Almost all of the clinical trial evidence reviewed by WHO’s guideline development group was considered low or very low quality, a persistent problem.in many medical guidelines dealing with pain.

The lengthy 274-page guideline takes a dim view of some commonly used therapies for LBP, such as muscle relaxants, anticonvulsants, steroids, opioids, transcutaneous electrical nerve stimulation (TENS), and injectable anesthetics – treatments that are primarily used in high-income countries. WHO recommends a more holistic approach to LBP, using therapies that are affordable and accessible to more people.

"Addressing chronic low back pain requires an integrated, person-centred approach. This means considering each person's unique situation and the factors that might influence their pain experience," Dr. Anshu Banerjee, WHO Director for Maternal, Newborn, Child, Adolescent Health and Ageing, said in a press release. "We are using this guideline as a tool to support a holistic approach to chronic low back pain care and to improve the quality, safety and availability of care."

WHO recommends that adults with chronic LBP start with treatments that are the least invasive and least potentially harmful. The values and preferences of patients should also be considered, as they are more likely to adhere to therapies they consider helpful.  

Recommended Treatments for Chronic LBP

• Patient education and counseling

• Exercise or physical therapy

• Acupuncture or dry needling

• Spinal manipulation (chiropractic care)

• Massage

• Cognitive behavioral therapy or mindfulness

• NSAIDs

• Topical cayenne pepper

The guideline states that opioid analgesics “should never be used as a stand-alone treatment” for chronic LBP. When opioids are used alongside other therapies, the lowest dose should be prescribed and only for a short duration, according to WHO.

Recommendations against routine use are also made about many other pharmaceuticals, including antidepressants, anticonvulsants, muscle relaxers, glucocorticoids (steroids), weight loss drugs, and injectable anesthetics such as lidocaine or bupivacaine.  

No recommendations are made about benzodiazepines, cannabis or acetaminophen (paracetamol), primarily due to lack of evidence, but also because of potentially harmful side effects. Cayenne pepper is the only herbal remedy recommended by WHO.

The guideline does not address surgical procedures such as spinal fusions and spinal cord stimulators, or invasive procedures such as epidural injections.

WHO’s 25-member guideline development group included a broad range of clinical experts from around the world. Among them is Roger Chou, MD, a researcher and longtime critic of opioid prescribing who heads the Pacific Northwest Evidence-based Practice Center. Chou is a co-author of the 2016 and 2022 CDC opioid guidelines, and has collaborated on several occasions with members of Physicians for Responsible Opioid Prescribing (PROP), an anti-opioid advocacy group. Chou let his Oregon medical license lapse in 2022.

One of the clinical trials reviewed by WHO’s guideline group is a controversial Australian study – known as the OPAL study -- that found low dose opioids gave little relief to patients with short-term back and neck pain. The OPAL study has been panned by critics because the treatment period only lasted six weeks and used a formulation of oxycodone that would not normally be used in clinical practice. Nevertheless, it’s been cited as evidence that “prolonged opioid use” is ineffective.

In 2021, WHO updated its guideline on the treatment of chronic pain in children, recommending that prescription opioids only be used for children who are dying or seriously ill. An earlier WHO guideline that recommended more pediatric use of opioids was withdrawn in 2019, after two U.S. congressmen accused the United Nation’s health agency of being “corruptly influenced” by opioid manufactures.  

Millions of People Worldwide Are ‘Left Behind in Pain’

By Pat Anson, PNN Editor

A new report by the World Health Organization (WHO) warns that limited access to morphine and other opioids is leaving millions of people in many parts of the world suffering in preventable pain.

The report, “Left Behind in Pain,” calls morphine a low cost, essential medicine for relieving moderate to severe pain. But access to morphine and other opioids is inadequate in many low and middle-income countries, with consumption patterns in wealthier nations that don’t correspond to medical need. Over 95% of the world’s supply of opioids is distributed in wealthy countries, with only 0.03% distributed in low-income ones.

“Leaving people in pain when effective medicines are available for pain management, especially in the context of end-of-life care, should be a cause of serious concern for policy-makers,” says Yukiko Nakatani, MD, WHO Assistant Director-General for Medicines and Health Products. “We must urgently advocate for safe and timely access to morphine for those in medical need through balanced policy, everywhere.”

The report calls for expanded access to morphine through local and regional distribution centers, changes in restrictive laws and guidelines, and reduced stigma surrounding opioid use.

“Some historical events, cultural beliefs, misinformation and disinformation about pain, and social stigma related to opioid use are known to have caused mistrust of opioids and contributed to fear of using them,” the report found.

Lawsuits and regulatory controls on the pharmaceutical industry are so strong in some countries that drug makers have stopped manufacturing morphine because the profit is low and risk of liability is high.

That may have played a role in Mundipharma’s recent decision to discontinue supplying Ordine, a liquid formulation of morphine, to Australia. Mundipharma is owned by the Sackler family, which has been enmeshed in opioid litigation over its role in the opioid crisis in the U.S. through its operation of Purdue Pharma.

A Mundipharma spokesperson told the Australia Broadcasting Corporation that the company’s third-party manufacturer decided to stop producing Ordine and that "sourcing another manufacturer would not be commercially viable."

Evolving Stance on Opioids

WHO’s position on opioids has evolved over the years. WHO’s guidelines for treating chronic pain, for example, used to say that opioids “are known to be safe and there is no need to fear accidental death or dependence.”

That changed in 2019, after two U.S. congressmen – without any real evidence -- accused WHO of being “corruptly influenced” by opioid manufactures. WHO withdrew the guidelines a month later, citing “new scientific evidence” – although critics said caved in to political pressure and threats to withdraw U.S. funding of WHO.

In 2021, WHO backpedaled further, recommending that morphine only be given to sick children when they are dying. Physical therapy and “biopsychosocial” treatments such as cognitive behavioral therapy were suggested as alternatives for children who are in pain, but expected to live.

WHO’s latest report recognizes the potential harms of opioids, couched in language about the world facing two opioid crises.

“The world is facing two crises related to the use of opioids. In the first, inappropriate use and over-prescription combined with the wide availability of illicit unregulated opioids, such as fentanyl, in some countries is causing significant harm and loss of life. In the second, a lack of access to opioids such as morphine in many parts of the world means that millions of people continue to suffer preventable pain,” said Nakatani.

About 80% of the world’s morphine supply was consumed in North America in 2021, primarily in the United States, although the rest of the developed world is catching up. Opioid consumption in the U.S. has fallen so sharply in recent years that Canada, Australia and several European countries have become the highest consumers of opioid analgesics, according to a 2022 study that ranked the U.S. as being 8th in per capita opioid sales.

WHO Panel Finds Insufficient Evidence to Review Kratom

By Pat Anson, PNN Editor

An advisory committee of the World Health Organization (WHO) has concluded there is insufficient evidence to recommend a “critical review” of kratom, which potentially could have lead to international controls on the herbal supplement used by millions to treat pain and other medical conditions.

WHO’s Expert Committee on Drug Dependence (ECDD) recommended that kratom and its two active ingredients, mitragynine and 7-hydroxymitragynine, be kept under WHO surveillance. Under international treaties, WHO is required to give an annual assessment of psychoactive substances and advise the United Nations on whether they pose a public health risk.

The ECDD’s report said regular use of kratom can lead to dependence and mild withdrawal symptoms, but that serious adverse effects were rare. Kratom comes from the leaves of the mitragyna speciosa tree in southeast Asia, where it has been used for centuries as a natural stimulant and pain reliever.

“Kratom is used for self-medication for a variety of disorders but there is limited evidence of abuse liability in humans,” the ECDD said. “Kratom can produce serious toxicity in people who use high-doses, but the number of cases is probably low as a proportion of the total number of people who use kratom. Although mitragynine has been analytically confirmed in a number of deaths, almost all involve use of other substances, so the degree to which kratom use has been a contributory factor to fatalities is unclear.”

‘Great Victory for Kratom Consumers’

In recent years, millions of Americans have discovered kratom and use it to self-treat their pain, anxiety, depression and addiction. Kratom is legal in most states, although some states and communities have banned it. The Food and Drug Administration has tried -- unsuccessfully so far – to schedule kratom as a controlled substance, which would effectively ban its sale and use in the United States.

The ECDD report was cheered by kratom advocates, including some who believe the FDA asked WHO to review kratom.

“It is a great victory for kratom consumers, for science and for the truth,” said Mac Haddow, a lobbyist for the American Kratom Association, a group of kratom vendors and consumers. "There can be no doubt that kratom should not be scheduled and that it should be responsibly regulated to protect against dangerously adulterated kratom products."

In a notice published in the Federal Register in July, the FDA called kratom “an increasingly popular drug of abuse” and said it was being “misused to self-treat chronic pain and opioid withdrawal symptoms.” Over 8,500 people responded to the FDA notice, most of them critical of the agency’s stance on kratom.

“When the FDA proposes that a natural substance like kratom be banned it is not because it’s dangerous to the public, it’s because it poses a threat to the pharmaceutical industries profits. These people have a financial interest in stopping a safe and natural substance from competing with high priced drugs,” wrote one anonymous poster.

“I suffer from chronic pain from an illness that no medication was able to help except for opioids. I became addicted, I lost my home and my job, and I was homeless for years dealing with an opioid addiction,” wrote Stewart Abe. “Kratom not only helps me get over that addiction, but it also helps me deal with the pain so I can be a functioning member of society. Without this plant in my life, the pain would be so horrific that it would not be worth living.”

“Kratom has helped countless people get away from addictive opioids and alcohol. It has all but saved my life from alcoholism and I haven’t drank in 8 years now,” wrote Davis Matthew. “Kratom has completely turned my life around and without it who knows how my life would have turned out.”

The legal status of kratom in Southeast Asia is mixed. In August, Thailand decriminalized kratom, dropped thousands of pending criminal cases involving the drug, and freed 121 inmates convicted of kratom crimes.

Hong Kong authorities recently banned kratom and seized a shipment of 2.5 tons of kratom powder that were enroute to Florida from Indonesia. Kratom use is banned domestically in Indonesia, but kratom farming is still permitted. Most kratom exports come from Indonesia, where it is considered an important cash crop.

Thailand Decriminalizes Kratom as WHO Considers Banning It

By Pat Anson, PNN Editor

For the first time since World War II, it is legal again in Thailand to grow and sell kratom, a tropical tree used for centuries in Southeast Asia as a natural stimulant and pain reliever. In 1943, the military junta that ruled Thailand banned the planting of kratom trees because the popularity of kratom in rural areas was interfering with tax revenue from the opium trade.  

Ironically, the decriminalization of kratom in Thailand comes as the World Health Organization (WHO) considers placing international restrictions on kratom and six other psychoactive substances.

With kratom no longer listed as a narcotic in Thailand, thousands of pending criminal cases involving kratom are being dismissed and 121 inmates convicted of kratom crimes will be released from prison. Possession of kratom had been punishable by up to two years in prison.

In recent years, Thailand has been liberalizing many of its drug laws to ease pressure on its justice system. There was also growing recognition that kratom could become an important cash crop for Thai farmers. The global trade in kratom has grown significantly in recent years, with millions of Americans using kratom to self-treat their pain, anxiety, depression and addiction. Most kratom exports currently come from Indonesia.

It remains illegal in Thailand to mix kratom with other drugs. Some recreational users boil the leaves and mix it with codeine cough syrup, creating a “kratom cocktail.”

"To decriminalise kratom is the right thing to do. Local people or patients who need it will be able to access it more easily. However, I am concerned that teenagers will use it in a wrong way, for example, mixing kratom with other narcotics. We have to control this strictly, otherwise, it can cause damage," Ramdin Areeabdulsorma, a Thai politician, told the Associated Press.

‘Kratom Saved Me’

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

Kratom is legal in most U.S. states, although some states and communities have banned it. The Food and Drug Administration has tried -- unsuccessfully so far – to schedule kratom as a controlled substance, which would effectively ban its sale and use in the United States.

Today is the last day for people to submit comments on the Federal Register for the FDA to consider as it prepares its response to WHO. Over 8,500 comments have been received so far, the vast majority asking the FDA and WHO not to ban kratom.  

“Kratom saved me from a lifetime opiate addiction. At 45 years old, I was unemployable and on my way to prison or death. Methadone or Suboxone hadn't kept me clean,” wrote Cecelia Lore. “I have never abused (kratom) as I hear some do. It has never caused a disruption in my life. I honestly feel that you should be looking at soda and junk food as the real dangers to our communities.”

“Kratom has helped both my wife and I stop taking opioids altogether. We never experienced withdrawals and we continue to use kratom rather than any other pain reliever because of its cost, lack of addictive nature and overall effectiveness. Rather than any kind of ban, what we need is regulation of the quality of the products,” said Nick Simpson.

“Kratom has made a direct impact on my life by helping me quit a debilitating alcohol addiction. I was an alcoholic for 6 years and to the point of being hospitalized several times with seizures from withdrawals,” wrote Tyler Davis.  “(Banning kratom) would harm a very large number of people recovering from addiction and force many back to destructive lifestyles.”

The American Kratom Association, a group of kratom vendors and consumers, has claimed the FDA instigated WHO’s review of kratom as a way to bypass the drug scheduling process in the U.S. An FDA spokesperson denied that, telling PNN the agency “does not determine for the U.S. government which substances shall be proposed” for WHO to review.

FDA Seeking Public Comments on Kratom

By Pat Anson, PNN Editor

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

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

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

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

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

— FDA

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

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

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

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

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

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

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

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

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

WHO Guideline Only Recommends Opioids for Children Who Are Dying

By Pat Anson, PNN Editor

The World Health Organization (WHO) has released new guidelines on the treatment of chronic pain in children, recommending that prescription opioids only be used for children who are dying or seriously ill and not expected to recover.

The 56-page guideline calls access to pain management a “fundamental human right,” while at the same time warning that “evidence of the effectiveness and safety of opioids is completely lacking in children.”

The guideline emphasizes the use of physical and psychological pain therapies, while taking a cautious approach to opioids. Morphine is only recommended for children in palliative care and those with “life-limiting” conditions for which there is no cure and “an early death is expected.”

“Children who are appropriately prescribed morphine for chronic pain in the context of end-of-life care or in children with life-limiting conditions, may require morphine for the management of intercurrent, acute or breakthrough severe pain,” the guideline states.

“Time-limited use of morphine in these contexts should be at the lowest appropriate dose and duration possible and must be regularly reviewed in order to ensure the fewest possible adverse events. Healthcare providers and caregivers need to perform frequent and repeated reassessments of pain and other symptoms, and the principles and relevant guidelines for acute pain management should be followed, including having an opioid stopping plan.”

The new recommendations for children between 0 and 19 years of age are a marked departure from previous WHO guidelines for chronic pain, which said that opioids “are known to be safe and there is no need to fear accidental death or dependence.”

Those guidelines were withdrawn in 2019, after two U.S. congressmen accused the United Nation’s health agency of being “corruptly influenced” by opioid manufactures.  A coalition of palliative care organizations objected, saying WHO caved-in to political pressure.

“We are extremely concerned that the withdrawal of these guidance documents will lead to confusion and possible extreme measures that will hinder access to patients with legitimate medical needs,” the coalition said in a joint statement. “Lack of availability and limited access to these medications for legitimate medical treatment is a human rights violation.”

‘Very Low Certainty’ of Evidence

Most of the recommendations made by a WHO advisory panel – the Guideline Development Group (GDG) — are vague, conditional and based on “very low certainty” of evidence. One of GDG’s members was Andrew Kolodny, MD, a psychiatrist and addiction specialist who founded Physicians for Responsible Opioid Prescribing (PROP), an anti-opioid activist group.

Despite an admitted “paucity of high-quality research” on how to treat pain in children, the GDG recommended that children be treated from a “biopsychosocial perspective” that incorporates physical therapy and psychological interventions such as cognitive behavioral therapy.  

“Children with chronic pain and their families and caregivers must be cared for from a biopsychosocial perspective; pain should not be treated simply as a biomedical problem,” the GDG said.

There is surprisingly little discussion in the guideline about the risks and benefits of non-opioid drugs such as acetaminophen. Some of the recommendations border on platitudes, such as treatment being “child and family-centered” and “tailored to the family’s values, cultures, preferences and resources.”

One area where the GDG is adamant is the importance of treating childhood pain to prevent it from becoming a lifetime problem.

“Exposure to chronic pain in early life may have implications for the incidence, severity and duration of chronic pain, and may be associated with long-term, maladaptive neurological changes,” the guideline warns.

“Chronic pain in childhood is associated with progression of pain into adulthood and potentially predisposes these children to other chronic health problems in later life. The negative impacts of chronic pain also extend to family members who report a higher burden of care and a detrimental effect on family function. As such, chronic pain during childhood has a very significant negative impact on the child over their life course as well as their wider family unit, making appropriate diagnosis and management essential.”  

The GDG said large, multi-center trials are needed to examine the safety and efficacy of virtually all pain management therapies. Additional research is also needed for children suffering from cancer pain and those with developmental and intellectual disabilities.

Former President Trump withdrew the United States from WHO last year in a dispute over its handling of the COVID-19 pandemic. President Biden reversed that decision on his first day in office.  

WHO Criticized for Withdrawing Opioid Guidelines

By Pat Anson, PNN Editor

A coalition of international palliative care organizations is protesting a decision by the World Health Organization (WHO) to withdraw two guidelines for treating pain with opioid pain medication.

“We are extremely concerned that the withdrawal of these guidance documents will lead to confusion and possible extreme measures that will hinder access to patients with legitimate medical needs,” the coalition said in a joint statement released this week.

The guidelines were withdrawn after two U.S. congressmen released a report that accused WHO of being “corruptly influenced” by Purdue Pharma and other opioid manufactures when it developed the guidelines in 2011 and 2012. The guidelines for treating pain in adults and children state that opioids “are known to be safe and there is no need to fear accidental death or dependence.”

Reps. Katherine Clark (D-MA) and Hal Rogers (R-KY) said the WHO guidelines served as “marketing materials” for Purdue, the maker of OxyContin.

“We are highly troubled that, after igniting the opioid epidemic that cost the United States 50,000 lives in 2017 alone… Purdue is deliberately using the same playbook on an international scale,” the report said. “If the recommendations in these WHO guidelines are followed, there is significant risk of sparking a worldwide public health crisis.”

WHO withdrew the guidelines a month after the report was released, citing “new scientific evidence” that emerged since their publication.

WHO’s decision to withdraw the guidelines gave credibility to a congressional report based largely on innuendo, according to the statement released by over a hundred palliative care organizations, including the American Academy of Hospice and Palliative Medicine and the UK-based International Observatory on End of Life Care.

“The report contains serious factual inaccuracies and draws inaccurate and unfair conclusions. It includes misleading information, and by making false accusations of existing collaborations and alliances to advance pain relief and palliative care, concludes that there was corruption within WHO,” the coalition said. “No staff member of the offices of the U.S. representatives contacted any of the organizations or individuals mentioned in the document to seek our responses to the allegations made in the report.”

According to the coalition, the withdrawal of the guidelines could further impede the availability of pain medication in third world countries, where less than 2% of palliative care patients have access to opioids.

“Under-treatment of severe pain is reported in more than 150 countries,” the coalition said. “At least 5 billion people live in countries affected by the crisis of under-consumption, and more than 18 million annually die with untreated, excruciating pain.”

The coalition cited the case of a cancer patient in New Delhi, India, who wanted to die until she was able to obtain opioids through a CanSupport palliative care program.  

“I am a functioning human being in charge of my life once again. This has been made possible thanks to the oral morphine that I now take.”

— Cancer patient in New Delhi, India

“I was a human wreck. My family was at their wits end as to how to help me. Because of my excruciating pain, I could not sit, sleep, eat or drink, let alone speak or think. When the team first met me my first request to them was for an injection that would put me out of my misery,” the patient said.

“Today, I am a functioning human being in charge of my life once again. This has been made possible thanks to the oral morphine that I now take on a regular basis.”

The palliative care coalition said it was unfair to deny opioids to patients in third world countries because of abuse and addiction problems in the U.S. and other developed nations.  The coalition called on WHO to update and revise the guidelines “with all deliberate speed” and to reinstate them until the revisions are made.

WHO Recognizes Chronic Pain as Disease With New Coding System

By Pat Anson, PNN Editor

The World Health Organization has adopted a new classification system for chronic pain, assigning it the code ICD-11 in a revision of the International Classification of Diseases (ICD). It’s the first time the ICD will include a specific diagnostic code for chronic pain, along with sub-codes for several common chronic pain conditions. 

The new classification system is important because it treats chronic pain as a distinct health condition and as a symptom to an underlying disease. It also takes into account the intensity of pain, pain-related disability, and psychosocial factors that contribute to pain.

“The inclusion of the new classification system for chronic pain in ICD-11 is an important milestone for the pain field,” says Lars Arendt-Nielsen, MD, President of the International Association for the Study of Pain (IASP), which headed a task force that developed ICD-11.

The new coding system will make it easier for physicians to diagnose, classify and get treatment for chronic pain patients. Insurers will use the new codes to authorize payments and researchers can use them to more easily track and measure the effectiveness of therapies. That’s the good news. 

The bad news is that the ICD changes won’t formally take effect until January 1, 2022. 

Under the current system, chronic pain conditions are poorly categorized under the code ICD-10, which makes it difficult for complex conditions such as fibromyalgia and Complex Regional Pain Syndrome (CRPS) to be classified. That led some physicians to diagnose patients with unexplained pain as having a somatic symptom disorder. 

“A diagnosis of somatic symptom disorder implies that the pain is caused by a behavioral, that is, mental condition. However, it is not appropriate to diagnose individuals with a mental disorder solely because an alternative medical cause cannot be established,” Jaochim Scholtz, MD, an IASP task force member, explained in Practical Pain Management.  

Under the new coding system, patients with fibromyalgia or CRPS could be classified as having a “primary pain” disorder, one of seven new sub-codes for chronic pain conditions:

1. Chronic primary pain

2. Chronic cancer-related pain

3. Chronic post-surgical or post-traumatic pain

4. Chronic neuropathic pain

5. Chronic secondary headache or orofacial pain

6. Chronic secondary visceral pain

7. Chronic secondary musculoskeletal pain.

There is some overlap between the different diagnostic codes. For example, neuropathic pain can be a symptom of cancer or chemotherapy, while trigeminal neuralgia could fall under neuropathic or orofacial pain. The idea is to give physicians a range of codes to choose from instead of the limited choices they have today.

“The integration of chronic pain in ICD-11 sends a strong signal that pain will achieve appropriate representation in this international standard for reporting diseases and health conditions,” said Scholtz. “The coding system also provides fundamental information for the identification of health trends and healthcare planning. It is widely hoped that the new systematic classification of chronic pain in the ICD-11 will support epidemiological, and other research that is essential for the development of future health policies.”

The classification system was outlined in a free online article published in the January 2019 issue of PAIN.

Strong Support for Cannabis Rx in Comments to FDA

By Pat Anson, Editor

The Food and Drug Administration may have gotten more than it bargained for when it asked for public comments about the medical value and abuse potential of 17 different drugs.

The agency wound up getting over 6,400 comments in the Federal Register, the vast majority of them from people advocating for cannabidiol (CBD) -- one of the active ingredients in medical marijuana.  

Unlike tetrahydrocannabinol (THC), the substance in marijuana that makes people high, CBD-based oils and medications relieve pain, and are increasingly being used to treat a variety of medical conditions.  

“CBD's are not a way to get high as THC is. These oils have so many beneficial uses for anxiety, stress, pain, joint issues, muscular issues, arthritis, seizures, Parkinson's, cancer,” wrote Tami Camp in her public comment. “We need natural herbs, not man-made poisons!”

“CBD helps me with my chronic nerve pain, in a way that prescription medications can't match,” wrote Jason Turgeon.

“I've been consistently using CBD oil now for three months and have noticed an uptick in my moods, a reduction of joint pain, and my sleeping cycles at night have improved as my sleep is deeper and I wake up feeling refreshed,” wrote Kerry Meier.

Public opinion polls show that these are not isolated comments or marijuana supporters trying to game the system by flooding the Federal Register with comments. A recent poll by CBS News found 85% of Americans favor medical marijuana use.

But while medical cannabis may be legal in 29 states and the District of Columbia, marijuana is still classified as an illegal Schedule I controlled substance by the Drug Enforcement Administration, right alongside heroin and LSD.

The FDA opened the cannabis can of worms at the behest of the World Health Organization (WHO), which is not only reviewing the safety and effectiveness of CBD, but 16 other drugs -- including pregabalin, tramadol, ketamine, and several chemical cousins of fentanyl, a synthetic opioid blamed for thousands of overdose deaths. 

WHO is seeking input from the FDA on whether international restrictions should be placed on any of the drugs. Under the Controlled Substances Act, the FDA was required to seek public comment in the Federal Register before responding to WHO -- perhaps not anticipating the overwhelmingly positive response that CBD would get. 

“Cannabidiol should not be restricted because CBD is not addictive, nor does it have the potential for abuse nor should it be tied to hallucinogenic drugs. Therefore, no international restrictions should be placed on CBD,” wrote Steve Easterly.

“For cannabis to be scheduled as a class I drug is ludicrous especially when the entire prohibition of cannabis was based on lies,” wrote Mike Copple. “What a shameful spectacle that we the people still have to argue about the usefulness of the cannabis plant. Cannabis has and continues to help me in many ways both physically and mentally.”

“I want cannabis to be legalized and available for over the counter sale. I have known several people who have benefited for various conditions from anxiety, depressions, MS, arthritis and epilepsy,” wrote Nancy Scott-Puopolo.

The public comment period ended on Wednesday. You can look at other responses in the Federal Register by clicking here. 

Mixed Reviews of Lyrica

There were only a few dozen comments about pregabalin (Lyrica), a prescription medication that millions of Americans take for fibromyalgia, neuropathy and other chronic pain conditions. As PNN has reported, WHO is investigating reports that pregabalin is being abused by addicts.

“Patients are self-administering higher than recommended doses (of pregabalin) to achieve euphoria, especially patients who have a history of substance abuse, particularly opioids, and psychiatric illness,” WHO told the FDA..

The public comments about pregabalin were mixed at best.

“I have been on several medications prior to being switched to Lyrica about six months ago. I actually feel nothing while taking the drug, and assume you would indeed have to take lots to maybe feel high,” wrote Mary. “Not sure if it helps my fibromyalgia or not since I still have lots of pain.”

“I take pregabalin in Lyrica form twice a day currently for nerve pain and fibromyalgia. I cannot accurately express the relief this has brought me,” wrote Renee.

“I have tried many, many medications. When I tried Lyrica, the side effects were horrible. I couldn't even lift my head without severe dizziness and the room spinning,” said Lora Berry.  

“I take Lyrica and all I got from it was fatter,” said Debra Winegar. “CBD oil is wonderful. Take a few drops under the tongue and I'm good to go. Narcotics are needed when my pain is out of control. I'm tired of waiting to be pain free. Legalize pot now!”

Will the FDA now report to WHO that thousands of American citizens want CBD-based medications fully legalized?  The FDA notice in the Federal Register only notes that public comments “will be considered” when the FDA prepares its scientific and medical evaluation. The FDA report to WHO is due September 30.

WHO Lists Fentanyl as ‘Essential Medicine’

By Pat Anson, Editor

At a time when hundreds – perhaps thousands – of Americans and Canadians are dying every month from overdoses of illicit fentanyl mixed with heroin or turned into counterfeit painkillers, it’s easy to lose sight of the fact that prescription fentanyl is an important and useful analgesic.  

We were reminded of that today by the World Health Organization (WHO), which added fentanyl skin patches and methadone to its list of essential medicines for treating cancer pain. WHO’s Essential Medicine List is not widely followed in developed countries – where prescription drugs are widely available – but it is used in many third world countries to guide decision making and increase access to medicines that are often in short supply.

"Safe and effective medicines are an essential part of any health system," said Dr. Marie-Paule Kieny, WHO Assistant Director-General for Health Systems and Innovation. "Making sure all people can access the medicines they need, when and where they need them, is vital to countries’ progress towards universal health coverage."

Fentanyl patches and methadone are two of the 30 drugs being added to the Essential Medicine List, raising the total to 433 medicines considered vital in addressing public health needs. WHO also added drugs for treating HIV, hepatitis C, tuberculosis and leukemia; and gave new advice about the use of antibiotics.

While illicit, black market fentanyl has become a deadly scourge across the U.S. and Canada, prescription fentanyl is legally available in patches, lozenges and sprays to treat severe pain.  

WHO’s inclusion of fentanyl patches and methadone on the essential list is limited to the treatment of cancer pain. An expert panel that reviewed the medicines noted “there is a need for additional opioid treatment options” for cancer pain. About a third of cancer patients worldwide are undertreated for pain, and patients living in low or middle income countries often have limited access to opioid painkillers.  

Other opioids already on the essential list (for treating pain and palliative care) are codeine, morphine, hydromorphone and oxycodone . Aspirin, ibuprofen and paracetamol (acetaminophen) are on it too, although the latter is “not recommended for anti-inflammatory use due to lack of proven benefit.”

Gabapentin Rejected

It’s also worth noting the medications that did not make the updated WHO list. Tramadol was not approved as a treatment for cancer pain, while gabapentin (Neurontin) was rejected as a treatment for neuropathic pain.

WHO’s expert panel gave a scathing review of the application made by the International Association for the Study of Pain and the International Association of Hospice and Palliative Care for the inclusion of gabapentin; noting there were many cases of bias and data manipulation in the clinical studies used to support it. Also noted was the $430 million fine paid by Pfizer in 2004 to settle civil and criminal charges for a “marketing scheme” to promote Neurontin for unapproved uses.    

“The Committee acknowledged the serious issues on publication and outcome reporting bias as important ones,” the panel said. “The Expert Committee considered the uncertainty in efficacy estimates as a result of publication and outcome reporting biases in the currently available evidence for gabapentin. The Committee did not recommend inclusion of gabapentin on the EML (Essential Medicine List) for neuropathic pain on the basis of its uncertain benefits.”

While gabapentin is approved for neuropathic pain in the European Union and Australia, it is only approved for epilepsy and neuropathic pain caused by shingles in the U.S. Despite that limitation, gabapentin is widely prescribed “off label” to treat depression, anxiety, migraine, fibromyalgia and other chronic pain conditions.  About 64 million prescriptions were written in the U.S. for gabapentin in 2016, a 49% increase since 2011.
