Capsaicin works on nerves to ease joint discomfort, scientists say

(HealthDay News) — University of Buffalo scientists say they have found how capsaicin, the compound that gives chili peppers their fiery flavor, also works to relieve joint and muscle pain.

In a study appearing Tuesday in the journal PLoS Biology, researchers found that capsaicin flips on nerve-ending receptors that sense both pain and heat.

“The receptor acts like a gate to the neurons. When stimulated it opens, letting outside calcium enter the cells until the receptor shuts down, a process called desensitization,” study leader Feng Qin, an associate professor at the university’s School of Medicine and Biomedical Sciences, said in a news release issued by the institution.
The flood of calcium changes the levels at which the receptors detect pain signal. “In other words, the receptor had not desensitized per se, but its responsiveness range was shifted,” Qin said.

While capsaicin has been used in folk medicines for generations, knowing how it works in relation to PIP2 may lead to developing other analgesics that ease pain without first causing irritation on their own, the team said.

Finding Effective Treatment for Your Chronic Pain

Studies are underway to look into the effectiveness of alternative ways of delivering pain medications

By January W. Payne

Chronic pain is a problem that—when healthcare, lost income, and lost productivity are taken into account—is estimated to cost about $100 billion in the United States each year. More than a quarter of Americans age 20 or older, or about 76.5 million people, say they’ve experienced pain that lasted longer than 24 hours, according to the American Pain Foundation—and 42 percent have endured pain lasting longer than a year. Nobody keeps good long-term national stats, but if North Carolina’s experience is any guide, the numbers are on the rise.

A just-published study in the Archives of Internal Medicine found that the prevalence of chronic low-back pain in the state more than doubled, to 10.2 percent, between 1992 and 2006. Paul J. Christo, assistant professor and director of the Multidisciplinary Pain Fellowship at the Johns Hopkins University School of Medicine, calls undiagnosed, untreated, or undertreated pain a “significant public-health problem.”

Chronic pain encompasses a multitude of ills, from back pain, headaches, neck pain, and conditions like arthritis and fibromyalgia to pain that develops as a result of cancer treatment and lingers for months or even years. Low-back pain, migraines, and joint pain (particularly in the knees) are among the most common complaints, according to the National Center for Health Statistics. knee pains,

Still, while it may have different origins, chronic pain “can be viewed as an illness in its own right because of its effect on function,” says Russell Portenoy, chairman of the department of pain medicine and palliative care at Beth Israel Medical Center in New York City.

Studies have shown that some people with chronic pain have brain abnormalities, though the connection between that and pain is not well understood. One recent study, for instance, showed that women with fibromyalgia had blood flow abnormalities in a region of the brain known to discriminate the intensity of pain that were not observed on CT scans done in healthy women.

Another study showed that chronic pain may harm the wiring of the brain, as demonstrated on functional MRIs. Chronic pain may also be caused by a problem with the “fight or flight” response, Christo says. “We believe that in certain pain conditions . . . the stress response can worsen pain because that stress response releases a chemical called noroepinephrine. . . . And noroepinephrine binds to certain receptors in the body that trigger pain.”

“Pain is essentially an alarm system that is designed to grab your attention, and when it works properly, it signals harm or healing,” says Scott Fishman, professor and chief of the division of pain medicine at the University of California-Davis School of Medicine. When the body heals, the pain should dissipate, but “the nervous system can become injured,” Fishman says. “That’s when the symptom of pain becomes the disease of chronic pain.”

Finding relief can take quite an effort, since the causes are often not immediately clear and there is not a sure-fire treatment. The battle can require a team of experts, so the multidisciplinary pain clinics or pain management programs that have sprouted up at hospitals, rehab centers, and in free-standing facilities over the past decade or so may be of particular help.

The clinics provide an all-in-one setting for care that, in addition to pain management specialists who may be trained as neurologists, psychiatrists, physiatrists, or anesthesiologists, may include physical therapists, family and vocational counselors, and massage therapists, for example. (The American Chronic Pain Association offers advice on selecting a pain clinic.)

After a full assessment, tailored treatment may include medications from anti-inflammatory drugs to antidepressants to opioids. Since commonly prescribed opioid medications such as oxycodone, fentanyl, and morphine can cause addiction, the American Pain Society and the American Academy of Pain Medicine have just released the first comprehensive clinical practice guidelines to help physicians make treatment decisions.

The guidelines, published in the Journal of Pain, suggest that physicians regularly assess people taking long-term opioids and do periodic drug screenings of patients who are considered to be at risk for abuse or addiction. Meanwhile, the Food and Drug Administration announced plans this month to require the brand-name and generic makers of morphine, oxycodone, fentanyl, and methadone to assist with a plan to reduce the risks associated with the drugs.

Other treatment options include injections of steroids or other medications, nerve blocks that interrupt pain signals, physical therapy, alternative therapies, and psychological interventions such as cognitive behavioral therapy, biofeedback, and guided imagery and other relaxation techniques. Acupuncture, which some people with pain find helpful, is thought to ease pain by raising the level of endorphins in the body, Christo says. “Endorphins are sort of like opioids. . . . They are natural pain relievers,” he says.

“They are released when the body experiences pain—when you sprain your ankle, cut your finger, in response to injury.” Still, research offers conflicting conclusions about the pain-relieving effects of acupuncture. A review of 13 studies published last month in British Medical Journal found that acupuncture offered only a small level of pain relief for people with low-back pain, migraines, knee osteoarthritis, and postoperative pain.

Jennifer Phillips, 41, of Providence Forge, Va., saw 54 doctors before the fibromyalgia that caused her pain was diagnosed in 1996. Finally, after seeing an internist whose nurse had fibromyalgia, she found a routine that works for her: a combination of proper sleep (achieved, in part, using the tricylic antidepressant amitriptyline), daily supplements of vitamins, magnesium, and potassium, plenty of water, and a low-carb diet.

The search is on for greater relief. Studies are underway to look into the safety and effectiveness of alternative ways of delivering pain medications, such as an inhaled form of fentanyl that would get the drug into the patient’s system more quickly. For older people who have fractures of the spine, vertebroplasty and kyphotlasty—two minimally invasive techniques in which bone cement is injected into the collapsed bone in the spine—can result in “significant pain reduction,”

Christo says. In the ongoing debate over how best to handle back pain, a study just published in the Journal of the American Academy of Orthopaedic Surgeons finds that the most effective way to treat most degenerative disc disease cases is to combine physical therapy and anti-inflammatory medications, rather than having surgery.
While it may seem counterintuitive, people with chronic pain should try to get exercise. Experts say it is important to keep moving, both for the usual cardiovascular reasons and in order to avoid muscle atrophy. A supervised, individually designed exercise program, incorporating stretching or strengthening, may improve pain and functioning in people with chronic low-back pain, according to a 2005 study published in Annals of Internal Medicine.

A physical therapist or personal trainer can offer the necessary advice. In fact, staying in bed for more than a day or two can make back pain worse, according to the National Library of Medicine’s MedlinePlus.

Jeff Nance of Indianapolis, whose chronic pain is caused by degenerative disc disease and spinal stenosis of his lower back, recalls that he barely wanted to leave his home three years ago. Then he discovered the Meridian Health Group pain clinic in Indianapolis. Now he is working full time again, and he recently participated in an annual bike ride across the state of Indiana. Nance goes back to the clinic every few months for a check of his medications, and he sees a psychologist a couple of times a month.

“What we try to do is really recognize that people can have pain for all kinds of reasons, [and we] find as many of those causes as possible and treat them in the most specific fashion as possible,” says Michael Clark, associate professor and director of the Chronic Pain Treatment Program in the Department of Psychiatry and Behavioral Sciences at Johns Hopkins Hospital. “Ultimately, you’d like to get somebody well.”
