Dozens of pain patients and physicians are meeting in Helena, Montana this weekend at a pioneering medical conference focused on arachnoiditis -- a progressive spinal disease long thought to be incurable that leaves many patients disabled with chronic back pain.

The conference is being led by Dr. Forest Tennant, a pain management physician from southern California, who has developed a unique protocol to treat arachnoiditis with a combination of pain medication, hormones and anti-inflammatory drugs. Unable to get the same type of therapy where they live, desperate patients from as far away as Maine, Alaska and Florida have been traveling to see Tennant for treatment at his pain clinic in West Covina, a Los Angeles suburb.

“We’re making history today. In all my wildest dreams I never thought we’d be having an arachnoiditis seminar in my home state,” said Gary Snook, a Montana native and a patient of Tennant for over a decade. “If there is one thing that we can learn today, it's that this hopelessly incurable disease that we suffer from is not as hopeless as we once thought.”

It was Kate Lamport’s idea to have Tennant give a seminar on arachnoiditis in her hometown of Helena. The 33-year old mother of four developed spinal pain after a series of epidurals for child birth and bulging discs in her back. She was diagnosed with arachnoiditis last year and went to see Dr. Tennant in California.

“As I learned more about arachnoiditis, I realized how many people were struggling just getting a diagnosis and treatment,” Lamport says. “There are so many people who want to go see Dr. Tennant, but they can’t. He’s booked and they can’t afford to travel, so I wanted to put something together to give people an opportunity to come see him and learn from him.”

The arachnoitditis conference is not just for patients. Several physicians and practitioners are also attending, hoping to learn some of the therapies Tennant has developed over the past decade.  

“Physicians are simply not getting the education and training they need,” says Tennant. “I am just so frustrated by all of the patients who are calling and all of the physicians that are calling, the demand for knowledge. And so we need a new way of doing some training and some education. And this is my first attempt to step outside of the educational box, if you will, and see if this is a mechanism that will successful.”

Tennant has conducted extensive research on the disease and has launched an Arachnoiditis Education Project for physicians. He says patients respond much better to treatment when arachnoiditis is in its early stages, when the inflammation is limited to the arachnoid membrane that surrounds the spinal cord.

As the disease progresses, the inflammation causes scar tissue to build around spinal nerves, which begin to adhere or stick together, leading to adhesive arachnoiditis -- which causes severe pain and other neurological problems, such as burning and stinging sensations that can radiate from the back down to the feet. More advanced stages of arachnoiditis can lead to paralysis.

Growing Number of Cases

Once considered rare, arachnoiditis is appearing more frequently as interventional pain physicians perform more surgeries and epidural steroid injections as alternatives to opioids for back pain. Tennant estimates as many as one million Americans may suffer from arachnoiditis, many of them misdiagnosed with “failed back syndrome” or other spinal conditions. He says every pain practice in the country needs to familiarize itself with arachnoiditis.

“We’ve had a decade of some marvelous science that no one talks about. We talk about opioids, epidurals and all the problems, but we don’t talk about the good things that have happened scientifically that have helped us develop a protocol to treat spinal cord inflammation,” Tennant told Pain News Network.

One discovery is the role that specialized cells in the brain and spinal cord – called microglial cells -- have in protecting and nourishing nerve cells. When glial cells become hyperactive in response to an injury, they trigger an inflammatory response that causes chronic pain.  That inflammation needs to be addressed with corticosteroids, says Tennant, or pain medications will never be effective.

The second discovery is that the central nervous system uses oxytocin, progesterone, pregnenolone and other hormones to regulate microglial cells. Hormone supplements and injections can be used to boost hormone levels and keep microglial cells at healthy levels.

“These two discoveries are profound. If it had not been for these two things, we would not be doing this seminar. The protocol that I’ve developed is because of these discoveries,” says Tennant.

Treatment Lowers Use of Opioids

Tennant’s treatment protocol is complex and requires the “off-label” use of several different medications. But many of his patients report they’ve been able to lead more productive and active lives, while reducing their use of opioid pain medication.

“It’s allowed me to be more active. I’m less exhausted, I get around better. I don’t have to use a walker as much,” says Rhonda Posey of Texas, who started seeing Tennant in April. “I’m smiling more. I’ve got better spirit and I have hope.”

“I actually believe that I was close to dying last year,” says Nancy Marr of Los Angeles, who suffered from arachnoiditis for a decade before she started seeing Tennant last year. “I went to see Dr. Tennant because my pain physician all of a sudden was threatening to withdraw all of my opioid medication.”

Blood tests revealed that Marr had low hormone levels and her inflammatory markers were “off the charts.” After treatment by Tennant, she’s only taking half the oxycodone she used to need for breakthrough pain.   

“My inflammatory markers are within normal range and my hormone levels are up. I’m feeling much better. I do have flares, but I can do a lot more,” she says.

“I’m on less pain medication now than I’ve been on for years,” said Jerry Davis of Arizona, who believes his back problems stem from a case of meningitis. “I got off the fentanyl. I got off all the other stuff."

Davis said he can usually sleep through the night, no longer has to spend some days in bed, and can lead a fairly normal life.

"I wasn’t in a wheelchair, but I probably would be by now if I hadn’t found him,” he says.

At age 75, Tennant isn’t sure how much longer he’ll be practicing. But he’s determined to share what he’s learned with other doctors, so they can provide the same treatment and hope he's given to arachnoiditis patients. Tennant is planning to host another arachnoiditis seminar in Hattiesburg, Mississippi this October.
