Why Are Doctors Skeptical & Unhelpful about Chronic Fatigue Syndrome?
Reprinted with the kind permission of Julie Rehmeyer and The Last Word on Nothing

By Julie Rehmeyer

Eight years ago, collapsed on a neurologist’s examining table, I asked a naive question that turned out to be at the center of a controversy continuing to this day. I had just received a diagnosis for the illness that had been gradually overtaking me for the previous six years, and I asked, “So what is chronic fatigue syndrome?”

A week earlier, I’d woken up suddenly barely able to walk. “Fatigue” hardly described what I felt: “Paralysis” was more like it. My legs seemed to have been amputated and replaced with tubes of liquid concrete, and just shifting them on the table made me grunt like an Olympic weightlifter. Not only that, my very bones hurt. Most disturbingly, my brain felt like a swollen mass. Speaking required tracking down and spearing each word individually as it scampered away from me. I felt as capable of writing an article about science – my job – as of slaughtering a rhino with my teeth.

My neurologist’s face was blank as he pronounced, “We don’t understand it very well.” He could recommend no tests, no treatments, no other doctors. I came to understand that for him, “chronic fatigue syndrome” meant “I can’t help you.”

My neurologist’s understanding of the illness closely reflected that of most doctors, who typically believe two things about CFS: that it’s probably psychosomatic, and that there’s nothing doctors can do for these patients. Experts have known otherwise for decades. The result is that while patients don’t get the help they need, they often do get a helping of scorn.

The Department of Health and Human Services (HHS) has launched an effort to change these misperceptions, it says, arguing that the problem goes back to that very first question I asked: What is chronic fatigue syndrome? There are currently many competing definitions, and none of them has trickled down to doctors. So HHS has hired the Institute of Medicine, an affiliate of the National Academies, to develop yet another definition of the illness. The stated hope is that doctors will embrace a definition developed by such a prestigious institution and then learn about treatments.

But the CFS community of experts, advocates and patients has responded to this plan with a revolt. Fifty specialists in the illness (nearly all of them) wrote to HHS requesting cancellation of the contract, and hundreds of patient advocates and thousands of patients wrote in support of the experts. And unfortunately, this is just the latest in a long string of disputes between the federal agencies and the CFS community, disputes that have nearly derailed the central work of understanding a disease acknowledged by all to sometimes be as disabling as late-stage AIDS or heart failure.

At the time of my diagnosis, though, I was far too consumed with learning to cope to worry about the politics of CFS. A couple of weeks after my trip to the neurologist, I woke up feeling better enough to venture to the grocery store. By the time I put the bags in the car, though, I was quivering with exhaustion. That night I was too weak to turn over in bed. Overexertion, I realized, was my enemy, so I began a program of aggressive rest. Gradually, I got stronger and the limits lifted.

But over the next five years, I got worse again, then better, then worse. I consulted doctors, but when they couldn’t help much, I stopped. Each time I was stuck in bed, I scoured my activities, my diet, my environment, seeking a reason. Ultimately I concluded my illness might have been controlled by the Greek gods, creatures more irrational and capricious than the human mind can comprehend.

Then in 2011, I disintegrated. Day after day, I couldn’t get out of bed, couldn’t work, couldn’t even focus my eyes to read a novel. I flew across the country and staggered into the office of Dr. Nancy Klimas, an immunologist and CFS expert at the University of Miami. She smiled and said wryly, “Your legs aren’t working too well for you there! We should be able to get you feeling better.” I nearly cried.

She told me that although CFS didn’t yet have a cure, she and other researchers had discovered a lot about it. At that moment, many thought the retrovirus XMRV might be the cause, though she was growing skeptical and soon thereafter the theory was disproven. Regardless, she told me, she and her fellow researchers were certain the illness wasn’t psychosomatic. The physiological abnormalities in CFS patients were too consistent for that.

She soon confirmed those patterns in me: Some parts of my immune system barely functioned, while others were in overdrive. Several viruses had become reactivated in my body, causing mischief long after the initial infection was past. My heart couldn’t manage to pump enough blood to my brain when I stood up: After six minutes of standing still, my blood pressure fell to 80/52, my heart raced, and I begged to lie down lest I vomit or pass out.

One test I declined, the two-day exercise test. When CFS patients exercise to exhaustion two days in a row, their output plummets the second day though they work just as hard. In addition, their bodies flag at using oxygen, inflammation goes wild, and their very cells change, reading their genes differently. That pattern, called exercise intolerance, seems unique to CFS. The test can help prove disability and provide objective guidelines patients can use to regulate their activities, but it can also leave them even sicker for months.

Though Klimas couldn’t cure me, she helped. She gave me immune modulators so my immune system wouldn’t overrev as though I were fighting an eternal flu. She worked to improve my sleep. She prescribed beta blockers to steady my heart rate when I stood. The most effective treatment was astonishingly simple: Gatorade. Electrolytes increased my blood volume – typically a liter low in CFS patients – thereby stopping my blood pressure from dropping so dramatically. She also monitored me for cancers common in CFS patients, since our natural killer cells, the immune system’s designated cancer assassins, barely function.

I improved enough to work a little bit, and it was a tremendous relief to have a knowledgeable and compassionate doctor behind me. Still, Klimas (who also treats HIV/AIDS) says if she had to choose between having HIV and CFS, she’d unquestionably choose HIV. Two decades of well-funded research have made HIV a manageable chronic illness, while her CFS patients often remain disabled.

I was extremely fortunate to get such competent care. There are a dozen or two US specialists to treat the one million Americans with CFS, and most non-specialists are as hamstrung by lack of knowledge about the illness as the neurologist who diagnosed me. Somehow, doctors haven’t gotten the word that CFS is a physiological illness with physiological treatments that help. Once I grew so sick that the illness dominated my life, I couldn’t get the question out of my mind: Why?

Reading about the history of the illness made the situation seem far less inscrutable. The Centers for Disease Control and Prevention first investigated it in the mid-1980s, when a few hundred people near Lake Tahoe suddenly got symptoms much like mine. A couple of doctors documented abnormalities, also much like mine, and noted that the malady fit the profile of myalgic encephalomyelitis (ME), an illness that had cropped up sporadically for decades.

Purported epidemics usually turn out to be nothing more than coincidences, though, and CDC investigators found the abnormalities peculiar and the symptoms suspiciously diverse. They performed a quick investigation and wrote up a report downplaying the illness. But concern continued to grow, and a manuscript outlining the abnormalities was being prepared for the Annals of Internal Medicine. So investigators created a definition for the illness, but they kept it broad, disregarding the specific findings and requiring six months of fatigue along with several picks from a grab-bag of other subjective symptoms, like sore throat, swollen lymph nodes, and brain fog. They named it “chronic fatigue syndrome,” and they tacitly subsumed myalgic encephalomyelitis within this new illness (which the federal agencies now often call ME/CFS).

With such a broad definition, CFS suddenly applied to widely varying patients with few shared abnormalities. As a result, many doctors came to view the CFS grab-bag as a psychosomatic illness. The triviality of the name “chronic fatigue syndrome” reinforced the skepticism. After all, aren’t we all tired? The name makes the illness that made it nearly impossible for me to stand up or talk or do my job sound very much like the everyday tiredness most folks push through.

Enough good science would dispel this notion, but the illness hasn’t easily yielded its secrets.

More shockingly, federal agencies have often impeded progress. In 2005, the CDC broadened the definition still further, requiring low levels of symptoms other than fatigue, and the number of patients who qualified for the illness increased by six to ten times — including some depressed people, pregnant women, and people suffering from the side effects of drugs. This and other broad definitions have caused huge problems in the research, especially through confusing ME/CFS and depression.

The CDC has reinforced this confusion in a variety of ways. For example, a group of UK researchers primarily uses a still broader definition of the illness, requiring no symptoms at all other than fatigue. In 2011, this group released a large study in the Lancet evaluating graded exercise and cognitive behavioral therapy for CFS patients. Although the researchers claimed that the two were “effective treatments,” the study reported no improvements in employment, health insurance claims, or welfare claims. About 15 percent of patients reported feeling better, but after a year of treatment, patients were still unable to walk as fast as those in heart failure (on average), and there were no other objective signs of improvement. The finding was trumpeted in headlines around the world: “Got ME? Just get out and exercise, say scientists,” reported The Independent.

Rather than helping to clarify the muddle, the CDC increased it. It has long embraced graded exercise therapy, putting it prominently on its website and suggesting that exercise will restore even bed bound patients to daily functioning — though the UK study showed that such expectations are highly unrealistic. The website doesn’t point out the lack of evidence that exercise is safe or useful for severely ill patients (the UK study excluded them), and while it cautions against overdoing exercise, it doesn’t mention how difficult that can be to avoid and doesn’t mention the objective guidance patients might get from the findings from two-day exercise tests. On top of that, the website recommends cognitive behavioral therapy but almost none of the treatments I got from Klimas, like blood pressure regulation and increased monitoring for cancer. It is the primary source of information about the illness for most U.S. general practitioners, and as a result, many doctors recommend no treatments other than some symptomatic care along with therapy and exercise to all their CFS patients, without impressing on them the extreme care that is essential to exercise safely. For years, U.S. experts specializing in the disease have strenuously objected and pleaded for changes, but modifications have been only minor.

Little wonder, then, that doctors tend to be skeptical about whether the illness is real and have no idea how to treat it.

Money is the other big problem. In the late ’90s, the CDC diverted $13 million appropriated for ME/CFS research to other projects, lied to Congress about it, and was caught by a whistleblower. The government now spends a mere $5 million a year on this illness; by comparison, it spends $3 billion on HIV/AIDS (which also affects about a million Americans). Even Ian Lipkin, the famous “virus hunter” who helped disprove the theorized XMRV viral link to ME/CFS, couldn’t get the $1.2 million he needs to study the microbiome in ME/CFS patients from the government. He has now turned to crowdsourcing (with impoverished patients eagerly contributing).

This fraught relationship with the federal agencies is the backdrop for the revolt of the ME/CFS community in response to HHS’s latest plan to have the Institute of Medicine develop a new definition of the illness. The specialists who requested that the contract be cancelled argued that they had already developed a good definition themselves, one requiring exercise intolerance as well as abnormalities in neuroendocrine, immune and autonomic functioning. But HHS continues to use a broader definition and has instructed the Institute of Medicine to consider many definitions, including the very general ones that can make the illness appear psychosomatic. Furthermore, more than half the members of the Institute of Medicine committee have no professional experience with the illness. As Dr. Derek Enlander, an ME/CFS specialist at Mt. Sinai Hospital, put it, “Do you want a podiatrist to treat your grandfather with lung cancer?”

Klimas, my doctor (now at Nova University), was among those who signed the letter requesting that HHS cancel its contract with the Institute of Medicine. I asked her why she was concerned. “I’m afraid they’re about a year early,” she said. If HHS had waited, she explained, they could have developed a disease definition grounded in data, and that’s what will give a definition the heft needed to change attitudes. Just a year would be enough: Several large studies are now collecting tissues from more than a thousand patients and controls, looking for the telltale biological indicators that most effectively distinguish the two groups. Furthermore, Klimas said, without that evidence, a skeptical committee might dismiss the results of the many small studies that are now most revealing — and could as a result develop a broad definition that would exacerbate the current confusion.

HHS has pushed forward despite the intense concern from patients, advocates and professionals in the illness, and their seeming disregard undermines their effort. “If you have a great review but you don’t have buy-in from the vested communities, you’ll have problems,” says Leonard Jason of DePaul University, the leading expert in ME/CFS definitions.

These squabbles are heartbreaking when the needs of ME/CFS patients are so great. Even the high quality treatment I got from Klimas helped me only slightly. Later, I heard from patients who had significantly recovered through assiduously avoiding mold, and though I considered the theory wacky, I was desperate enough to experiment. And for me, it worked. I’m nearly recovered. I can go running, write articles, travel with my new husband – and every time I do, it feels like a miracle.

My strange experience leaves me with a thousand questions. Is mold sickening others with this illness? If indeed exposure to mold triggered my CFS, why did it make me so sick when many seem to tolerate it just fine? Do other environmental toxins contribute, or is mold the whole problem? Do only certain kinds of mold cause trouble, and if so, which ones? Could my experience offer a clue that would lead to a cure, or even better, prevention? And the many possible causes besides mold need to be investigated as well – viruses, autoimmune breakdowns, other toxins.

Personally, my confidence in the true experts on the panel (including, now, Klimas) is sufficient that I expect – guess – hope – that the Institute of Medicine will develop a definition that’s moderately specific. But it almost certainly won’t put the definitional controversy to rest or give rank-and-file doctors a current, scientific understanding of the illness. Doing those things will at a minimum require a definition that’s grounded in data — data that’s still being gathered.

And we need to do better than this. We shouldn’t be wasting so much money and energy on ill-conceived efforts. Patients should be treated with respect, both by their doctors and by the federal officers whose job is to guide the effort to research their illness. And our nation – for its own economic self-interest, if nothing else – should make an investment in researching this illness that is in proportion to the devastation it causes.

I found this to be one of the very best articles I have read in regards to simply and effectively stating the basic history and current climate of this disease. However, when I tried to rate it with 5 stars, I'm afraid that it registered as only one. Is there any way to fix that?? I've never rated an article before and thought I had to click on each star for it to show up. I would hate someone to disregard this due to a low rating on my part. It really is an excellent article and I am looking forward to reading the book.

My son and i both have the same issues.. but yet treated for two different diagnoses. I was just told i had insomnia but nothing ever really treated. Just given ambient, which never works. And cymbalta for fibromyalgia, depression anxiety. Still nothing works. My son on the other hand said he grew to much in a year and his fainting spells were due something called P.O.T.S. Syndrome. He sleeping issues as well. Was just insomnia depression, and anxiety. Was given seriquill and effexor. Still nothing on him. He was told to eat salty food and drink gatoraide. Due to his blood pressure dropping as well. Strange how we can all have same effects but none diagnosed same things.
