WE WANT TO HELP!

Getting help is a priority for people who are ill. This is especially important for ME/CFS patients who have lost their incomes because they are too ill to work. People who are so impoverished that they can’t afford food, clothing, and shelter face a struggle for survival on a daily basis. That struggle can overshadow all others – including the search for physicians and treatments – while patients scramble for their basic needs. The effort to stay alive is all-encompassing.

How will these patients get food to eat, pay their rent, and buy such bare essentials as shoes?

Who will help them when their options run out?

We will! AMMES has distributed over $85,000 to patients who are severely ill to help them with their basic necessities. We have helped pay for housing, medical care, food, utilities, and other essential needs. Please help us help them by spreading the word.

_______________________

Chronic Fatigue Syndrome is a disorder characterized by debilitating fatigue and recurrent flulike symptoms, such as muscle and joint aches, sore throat, swollen glands, and difficulty thinking. Fibromyalgia Syndrome is a disorder characterized by widespread muscle pain.

Can such different descriptions share anything in common?

Siamese Twins

Most experts agree that the symptoms of CFS and FM are so close that they are – for all intents – the same disorder. It’s a bit like Jekyll and Hyde, or perhaps like Chang and Eng Bunker, the Siamese twins made famous by P.T. Barnum. They were both the same “person” but had two different names, two similar but different personalities.

Assigning a Diagnosis

Patients who present to their primary care providers frequently relate a litany of complaints such as fatigue, vague aching, and trouble with memory or concentration.

Based on these complaints, the primary care doctor will most likely diagnose Chronic Fatigue Syndrome using the 1994 international case definition published by the Centers for Disease Control.

On the other hand,  the patient whose major complaint is pain will likely consult a rheumatologist who will ask, “Where does it hurt?” When it is determined that the patient hurts at the classical “tenderpoints” defined by the ACR [American College of Rheumatology] in 1990, the likely diagnosis will be Fibromyalgia.

Overlaps and Shadows

So one diagnosis is frequently given by primary care physicians and the other by rheumatologists. Both diagnoses have several features in common: exertional malaise [activity intensifying symptoms], cognitive difficulties, muscle pain (or myalgias) and a sleep disorder.

Both are frequently associated with “overlap disorders” or “shadow syndromes,” as I like to call them. The most common “shadow syndromes” are irritable bowel syndrome, irritable bladder, temperomandibular dysfunction, and mitral valve prolapse.

Others include premenstrual syndrome, primary dysmenorrhea, migraine, restless legs or periodic leg movements, Myofascial Pain Syndrome (MPS), chemical sensitivities, autonomic dysfunction (Neurally Mediated Hypotension and Postural Orthostatic Tachycardia Syndrome), Gulf War Syndrome, and possibly hyperextensibility, acne rosacea, Raynaud’s phenomenon, sicca complex (dry eyes and mouth) and vasomotor rhinitis (constant runny nose and congestion).

Note that the shadow syndromes occur predominantly in females, are defined clinically rather than by physical or laboratory findings, and many are associated with either pain or fatigue. It is likely that these disorders occur concurrently because they share a common biophysiological thread.

Fibromyalgia & CFS Compared

The symptoms are similar for both syndromes, including debilitating fatigue, post-exertional malaise, feverishness, sore throat, headache, joint aches, a feeling of generalized weakness, subjective swelling, non-radicular paresthesias (numbness or tingling that does not follow typical nerve patterns), memory loss, forgetfulness, confusion, irritability, and depressed mood.

There are some subtle differences, however. (See Table 1 at end of article.)  Historically, CFS is frequently triggered by a flulike or infectious illness, but sometimes occurs after trauma or surgery. FM, on the other hand, is frequently triggered by trauma, less often by an infectious process.

While there is a preponderance of women in both disorders, women are more likely to have FM (9:1) than CFS (7:3). The median age for both disorders is about 40 years, although all age groups are vulnerable, including children and seniors. Familial aggregations and overlapping HLA haplotypes are described for both disorders.

Physiologically, both disorders have in common reduced midbrain and cortical blood flow; autonomic dysfunction such as symptomatic orthostatic tachycardia and neurally mediated hypotension;  suppression of the hypothalamic pituitary axis; disturbed Stage 4 sleep; reduced serum or CSF serotonin levels; and suppression of growth hormone, somatomedin C, or IGF1. (Similarities are summarized in Table 2.)

Substance P, a neurotransmitter responsible for the transmission of pain is elevated in persons with FM (but not CFS); and RNaseL, a cellular antiviral enzyme is frequently elevated in CFS (but not in FM). These differences may reflect why pain is a key symptom in FM, and viral symptoms predominate in CFS.

Treatment

The treatment of CFS and FM is hampered by the absence of a known cause and pathophysiology. In such instances, treatment is generally limited to supportive care and symptomatic therapy. Thus a prudent diet, basic supplementation, and traditional management of sleep disruption, pain, and autonomic symptoms are the standard course.

Counseling is helpful in coping with chronic illness and stress, and study after study has extolled the virtues of low level progressive exercise. Activity must be approached cautiously, however.

“Pure cases” of FM seem to respond with increased endurance and improved well-being to a progressive exercise program, while “pure cases” of CFS are more likely to respond with increased cognitive and flulike symptoms to a similar regimen. Thus, persons with CFS may have to start at a lower level and progress more slowly.

Pure Cases

There are certainly cases of “pure CFS” or “pure FM.” When there is no significant complaint of muscle pain, the patient would be diagnosed as having “pure CFS,” mostly characterized by fatigue, cognitive dysfunction, sleep disruption, and flu-like symptoms including vague muscular aching during relapses.

When cognitive symptoms are minimal and widespread muscle pain is the major complaint, the patient is thought to have “pure FM.” These make up a minority of the cases,  however, since about 70% of persons with CFS meet criteria for FM, and about 70% of persons with FM also meet criteria for CFS.

In most aspects Fibromyalgia and CFS are almost identical. There are subtle differences in biochemistry, prevalence, and perhaps response to exercise that separate them ever so slightly. CFS and FM may represent the extreme ends of a spectrum of multisystem disorders characterized by fatigue, pain, and female predominance.

Stress-inducible WASF3 regulates brain metabolism and cognitive function

Abstract:

Wiskott-Aldrich syndrome protein family member 3 (WASF3) disrupts mitochondrial respiration and is induced in association with endoplasmic reticulum stress in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). Because cognitive impairment is a hallmark of ME/CFS, we investigated the role of WASF3 in brain metabolism and function using WASF3 transgenic and knockout mouse models.

WASF3 disrupted respiratory complex IV and localized to mitochondria-associated membranes, known to modulate cellular processes important for neuronal activity. Overexpression of WASF3 in the hippocampus, a critical region for memory formation, induced a metabolic shift toward glycolysis and promoted a “hypometabolic” state. Increased WASF3 also caused a reduction in ATPIF1, previously shown to facilitate cognitive function, and impaired learning. Conversely, WASF3 deficiency increased ATPIF1 level, enhanced oxidative metabolism, and preserved cognitive function under stress.

Together, these findings demonstrate that WASF3 suppresses oxidative metabolism in the brain and contributes to cognitive dysfunction, providing mechanistic insights into the “brain fog” reported in ME/CFS.

CATCH-EVseq, an Ultra-Sensitive Capture Assay to Monitor Human Enterovirus RNA

Abstract:

The detection of low-abundance viral RNA in chronic or persistent infections remains a major challenge in virology, constrained by the sensitivity and specificity of traditional methods. One such infection, chronic enterovirus (EV) infection, has been proposed as a potential underlying factor in Myalgic Encephalomyelitis (ME), although this hypothesis remains debated. Supporting evidence for EVs as a viral trigger includes historical spatiotemporal overlaps between ME outbreaks and poliomyelitis epidemics, frequent reports of “flu-like” illness at disease onset, seasonal outbreaks patterns, and serological findings. To address the problem of EV detection, we developed CATCH-EVseq, an ultra-sensitive platform built on the CATCH framework.

By integrating high-throughput sequencing with cDNA capture using 49,847 probes targeting 3410 EV genomes, CATCH-EVseq achieved a detection limit in artificially created samples as low as one copy in a microgram of RNA for two out of three biological replicates. Additionally, spike-in controls allow for rigorous validation of the capture and sequencing throughout the CATCH-EVseq procedure. When applied to a small number of blood samples from both ME patients and healthy controls, CATCH-EVseq detected no EV RNA, either in direct assays or after in vitro viral amplification.

While these results do not support the presence of circulating EV RNA in the blood of individuals with ME, they do not rule out persistent infection in other tissues or organs. Critically, CATCH-EVseq establishes a robust, ultra-sensitive framework for future investigations of low-level EV persistence in biopsies, post-mortem tissues, or other clinical contexts where chronic enterovirus infection is suspected.

ME/CFS and the thalamus as a precision gate: what reversible thalamocortical connectivity reveals about central gain in post-infectious fatigue

Abstract:

Kim and colleagues report a finding that is easy to understate: thalamic hyperconnectivity with sensorimotor and visuo-occipital cortices, present in patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) at baseline, shifts back toward the pattern seen in healthy controls after hyperbaric oxygen therapy and does so most in the patients who improve clinically. To my knowledge, this is the first treatment-coupled, apparently reversible thalamocortical signature in ME/CFS.

Viewed through predictive processing (the framework in which the brain continually predicts its own sensory and bodily inputs), the thalamus is theorised to be a gain-control gate that helps set the precision or weight assigned to ascending bodily signals. I argue that the baseline hyperconnectivity reflects deficient filtering of expected input, and that its post-treatment reduction may index restored filtering. The same failure of attenuation offers a parsimonious account of several symptoms that often co-occur in patients, including sensory hypersensitivity, pain, orthostatic intolerance, and cognitive “brain fog”, as one mechanism expressed across exteroceptive, nociceptive, autonomic, and cognitive domains.

Because hyperbaric oxygen therapy is a vascular intervention and resting-state connectivity is an indirect measure this gain interpretation remains a hypothesis and I outline how it can be tested across exertion and post-exertional malaise rather than at baseline alone.

Overlapping Post-COVID Conditions: A Case of Myalgic Encephalomyelitis and Postural Orthostatic Tachycardia Syndrome Triggered by Sequential Epstein-Barr Virus (EBV) and Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Infections

Abstract:

The rise in post-infectious syndromes following COVID-19, such as Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) and Postural Orthostatic Tachycardia Syndrome (POTS), has become increasingly common in clinical practice, representing an emerging clinical challenge. This case highlights a possible clinical scenario involving the interaction between sequential viral infections – such as the Epstein-Barr virus (EBV) and Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) – in triggering overlapping chronic conditions. This report presents the case of a patient who developed ME/CFS and POTS following SARS-CoV-2 infection, with a prior history of EBV mononucleosis, and discusses the diagnostic, therapeutic, and pathophysiological implications.

A 48-year-old woman with a history of mononucleosis in childhood developed persistent and disabling symptoms after COVID-19 in January 2022. She presented with extreme fatigue, orthostatic intolerance, paresthesia, cognitive dysfunction, and multisystem symptoms. After extensive investigation, she was diagnosed with ME/CFS (early 2023) and POTS (later that year). Mast Cell Activation Syndrome (MCAS) was considered as a hypothesis during follow-up, but objective testing was not confirmatory. Management included pharmacological therapy (including low-dose naltrexone, duloxetine, and palmitoylethanolamide (PEA)), activity adjustments (pacing), and a multidisciplinary approach, with partial and fluctuating responses.

This case illustrates how viral infections such as EBV and SARS-CoV-2 may act as sequential triggers in an individual clinical trajectory compatible with the development of ME/CFS and POTS. The symptomatic overlap, the lack of readily available objective biomarkers in this patient, and the need for a predominantly clinical and functional diagnostic approach in her evaluation highlight the complexity of these conditions. This experience also underscores the importance of continued efforts in research, clinical training, and integrated care models to improve the management of patients presenting with post-COVID conditions (PCC).

Transient clinical improvement and immune modulation following recombinant Zoster vaccination in a patient with ME/CFS

Abstract:

Introduction: Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a debilitating multisystem disorder associated with immune dysregulation yet lacks definitive biomarkers or effective therapies. Acute immune perturbations may transiently modulate disease manifestations.

Methods: We report the case of a female patient in her 60s with severe, long-standing ME/CFS who experienced changes in symptom following administration of recombinant zoster vaccine (RZV; Shingrix). Peripheral blood mononuclear cells were analyzed pre- and post-vaccination using flow cytometry, with comparison to a female healthy control. Plasma galectin-9 (Gal-9) levels were quantified by ELISA.

Results: Both RZV doses were associated with rapid, transient remission of symptoms, including improved sleep, cognition, pain, mobility, and respiratory function, followed by relapse. Immunologically, pre-vaccination profiling revealed elevated monocytes, increased CD71+ erythroid cells, and features of T cell exhaustion marked by Gal-9/PD-1 co-expression and impaired cytokine responses. Post-vaccination, monocyte frequency decreased, Gal-9+/PD-1+ T cells were reduced, and NK cell degranulation improved, indicating partial restoration of immune function.

Conclusion: This case demonstrates that immune stimulation via RZV may transiently reverse immune dysfunction and improve clinical symptoms in ME/CFS. These findings support a role for reversible immune exhaustion in disease pathogenesis and highlight potential avenues for biomarker development and therapeutic intervention.

Recognizing and managing post-exertional malaise in primary care

Abstract:

Post-exertional malaise (PEM) is a syndrome characterized by a worsening of symptoms after physical, cognitive, or emotional exertion. It presents as increased fatigue, usually accompanied by other clinical symptoms, such as muscle pain or cognitive impairment. First described in patients with chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME), PEM is now recognized as a hallmark of post-infectious syndromes that have received increasing attention through the emergence of long COVID. PEM is a distinguishing symptom of these conditions, and its early detection and appropriate management are essential to prevent long-term functional decline of affected patients. This review describes the definition and clinical impact of PEM and summarizes current recommendations for its management.

Explaining Fatigue and Post-Exertional Malaise in Long COVID and ME/CFS: From Skeletal Muscle To Exercise Immunology

Abstract:

The SARS-CoV-2 viral outbreak in 2020 resulted in a record number of global hospitalizations and deaths. Although most people recover from an initial COVID infection within 3 months, around 10% of people have symptoms that do not improve after 3 months, which is called long COVID. Other viruses and bacterial infections can also result in long-term symptoms, which is known as myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS).

One of the most common symptoms of long COVID or ME/CFS is post-exertional malaise, which is the worsening of symptoms or development of new symptoms after physical, mental or emotional stress. This can lead to patients leading less physically active lifestyles. Physical activity is known to be beneficial for overall health and wellbeing, mostly by increasing exercise capacity, which is a significant predictor in long-term health. Physical inactivity.

It is thought that many symptoms of long COVID and ME/CFS can be explained by lower physical activity of patients. However, people who are less physically active don’t experience post-exertional malaise, implying there are disease-specific changes. Many of the benefits that come from exercise come from a persons ability to adapt to an exercise session. Usually, exercise will create a short energy deficit, which then may result in small amounts of muscle damage. This then triggers a short-lived immune response, led first by neutrophils and macrophages, which result in activation of fibroadipogenic progenitor cells (FAP cells) and satellite cells (muscle stem cells). FAP cells and satellite cells communicate to repair damage to the muscle itself, while immune cells clear debris surrounding the muscle. In healthy situations, this creates a stronger, more resilient muscle. It is unknown whether these responses are still seen in long COVID or ME/CFS. The goal of this thesis then to 1) understand muscle changes in patients with long COVID and ME/CFS, 2) to better understand how these changes may relate to PEM, 3) to understand whether the muscle changes in patients are a result of physical inactivity.

Within the thesis, I find that patients with long COVID and ME/CFS have specific patterns of skeletal muscle that separate them from healthy individuals. This is highlighted by more fast-twitch fibre types, slow-twitch muscle atrophy, lower mitochondrial respiration that is separate from just mitochondrial loss, less metabolites related to oxidative capacity and antioxidation, less lipids that are required for cell membrane maintenance, and lower amounts of satellite cells and FAP cells.

Beyond this, I find that ME/CFS can be distinguished from long COVID by less capillaries, less slow-twitch fibres, less local immune cells, and lower amounts of several essential amino acids. As well, I find evidence that physical inactivity alone cannot explain long COVID and ME/CFS symptoms. Where all of long COVID, ME/CFS, and physical inactivity have lower whole-body aerobic capacity, physical inactivity causes a decrease in muscle fibre size, loss of mitochondria, increases in muscle lipotoxic lipids, and decreases in metabolites related to carnitine metabolism. These changes are not seen in either long COVID nor ME/CFS, and support the idea that long COVID and ME/CFS have disease specific muscle changes.

Overall, I find that the reduced whole-body capacity of long COVID and ME/CFS patients is not cause by physical inactivity, and is defined by reduced muscle oxidative ability. The lower amounts of local cells that would normally support exercise and damage responses are lower in both long COVID and ME/CFS, which partially explains the occurrence of PEM. This also suggests that patients experiencing PEM should not undertake normal rehabilitation, however it might be that more individually tailored, and severely monitored approaches may still be beneficial.

The Glymphatic–Meningeal Lymphatic System and Autophagy in ME/CFS and Long COVID: A Mechanistic Perspective

Abstract:

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and Post-Acute Sequelae of SARS-CoV-2 infection (Long COVID) are complex multisystem disorders affecting 60–400 million individuals globally. They are considered post-infectious illnesses and share similar biological mechanisms, including immune dysregulation, orthostatic intolerance and cognitive dysfunction, highlighting a substantial overlap between the two conditions. Persistent fatigue, sleep dysfunction, post-exertional malaise and brain fog are among some of their most common and debilitating symptoms.
Despite extensive research, they remain incurable, with no effective treatments, or simple diagnostic tests. They are increasingly understood as heterogeneous, multisystem diseases, involving neurological symptoms, with varying severities and diverse underlying biological abnormalities. More recently, the possibility of glymphatic dysfunction and autophagy impairment have been proposed as parts of the mechanistic features of the pathophysiology of these conditions, which are discussed more fully in the present perspective.
With the glymphatic and meningeal lymphatic systems being operationally integrated, we will try to delineate how the metabolic waste removal mechanism afforded by this system may work together with autophagy to maintain brain homeostasis. We will provide some of the established mechanistic features of toxicity of misfolded proteins, explore their role in causing glymphatic dysfunction and impairing autophagy, and discuss the potential for therapeutic interventions.

“Mary Ann’s Transfusion”

by Dr. David Bell

This is the case history of a nurse who improved dramatically after a blood transfusion. It is excerpted from Dr. Bell’s book, Faces of CFS – Case Histories of Chronic Fatigue Syndrome, published in August, 2000. “Mary Ann’s Transfusion” illustrates one aspect of cases he has followed since the mid-1980’s. 

Reprinted with the kind permission of Prohealth.

***

Mary Ann was a bold and highly competent nurse in the intensive care unit of our local hospital, and I depended on her. Given that my specialty is pediatric medicine, I was always a little nervous treating adult patients who were in the midst of medical crises. I quickly learned I could count on the vivacious Mary Ann, who was then in her thirties, for the most up-to-date and reliable information about my patient’s status. Often, she suggested successful solutions to problems for which I had never been trained in medical school, like constipation. There should be a course on constipation in octogenarians who have suffered heart  attacks, but there isn’t.

In 1985, when the epidemic of CFS in Lyndonville began, eventually affecting more than two-hundred people in a town of 1,500 (or whatever), Mary Ann got sick, too, although some years passed before her diagnosis was readily apparent. The one constant, however, which began in 1985, was exhaustion. Mary Ann was weighted down with a panoply of other problems, as well: arthritis-like pains in her joints, sinus infections, allergies, migraine headaches, chest pain, shortness of breath. As the years wore on, these symptoms and many more resulted in her slide from being perhaps the finest ICU nurse I have ever known to little more than – in the eyes of the medical specialists she consulted – a hypochondriac. As a result, she was inhabiting a remorselessly bleak netherworld.

I tried to help Mary Ann, too, over the years. It was rapidly apparent to me, and eventually to her, that she had same disease from which so many of the patients she had met in the hospital in 1985 had suffered. I tried everything I could think of by way of drugs and other therapies to help her, but none of them worked to any appreciable degree. There was an aspect of her case that I found very interesting, perhaps because it seemed to me to be one of those elusive clues that might lead me to a more comprehensive understanding of the mechanism of the disease.

Mary Ann had a remarkable requirement for water. She rarely came into my clinic without a large container of ice water, from which she sipped continuously. I was pretty sure it was water, anyway; if it was vodka, I knew we were in for some big problems. It turned out not to be vodka, of course. Once, I asked Mary Ann to keep track of the amount of water she drank in one twenty-four hour period. Her consumption turned out to be four gallons a day. Persistent thirst is a sign of diabetes, and Mary Ann did indeed have diabetes, in addition to all her other problems. She had a rare kind, however, one called “diabetes insipidus,” which is not the “sugar diabetes” with which most people are familiar. In the primitive days of medicine, doctors would actually differentiate between the two forms of diabetes by tasting their patients’ urine. If the urine had a sweet taste, their diagnosis was sugar diabetes, known today more formally as “diabetes mellitus.” In the case of diabetes insipidus, the urine was tasteless, or “insipid.” Recalling this piece of medical history makes me wonder if I really want to return to the good old days of clinical medicine.

What struck me as most interesting about Mary Ann’s diabetes is the fact that it is caused by a deficiency of the brain hormone,  vasopressin, which, as I have noted, is a common finding in CFS sufferers. Among its many functions, vasopressin helps the kidneys absorb water and maintain the body’s fluid balance. When vasopressin is low, or missing entirely, water runs through the body without being absorbed, like a bucket with a hole in the bottom. Usually, diabetes insipidus signals damage to the pituitary gland in the brain, which manufactures vasopressin. Paradoxically, in spite of her gargantuan intake of water, lab tests suggested that Mary Ann was living in a state of perpetual dehydration.

I decided to measure the volume of blood circulating in Mary Ann’s body. In case anyone was wondering, it is not a good idea to measure someone’s circulating blood by taking it all out at once. Instead, a high-tech system deployed in a hospital radiology department requires only two small blood samples to determine the body’s entire circulating blood supply. A normal person has about five quarts of blood in their system. It turned out that Mary Anne had only 51 percent of the amount of circulating blood that would have been considered normal for a woman of her age and size.

This was a startling finding. If a person loses as much as 40 percent of their blood volume suddenly, they will usually die from shock. In science and in medicine, when one is trying to calculate what is “normal,” and what is “abnormal,” one will always encounter pitfalls. Mary Ann’s radically reduced blood volume caused me to think about what constitutes a true “normal” value for blood volume. Mary had gained weight in the course of her struggle with CFS, for instance, and I wondered if blood volume can be reduced in people who are overweight. I tried to come up with all sorts of explanations for Mary Ann’s radically low blood volume. In the end, I could draw only one conclusion: no matter what the mitigating circumstances of her case, Mary Ann’s blood volume was below normal.

The blood volume assay has been used for almost thirty years, and is considered to be highly reliable. The fact that Mary Ann – no matter how hard she tried – could not possibly fake the results of this particular test, seems especially significant to me given the vast array of medical experts who continue to insist that CFS is a psychosomatic condition. I will give my little finger to anyone who can successfully argue that this finding was psychosomatic.

I must confess that I am not the first doctor to discover that CFS patients have dramatically lowered blood volumes. Dr. David Streeten had been measuring the low blood volumes in CFS patients for some by the time I tested Mary Ann for the condition. Mary Ann just happened to be my first patient in whom I personally observed the phenomenon.

Dr. Streeten and I, being doctors, were excited by these findings and were enjoying our collaboration. Mary Ann, the patient, was enjoying very little about her life. In fact, she told me she was eager to experiment with therapies. I felt that her informed  consent was reliable, in part because of her nursing experience, which had left her well-versed in medical matters, and because she was, in my opinion, entirely rational. Thus, in December of 1997, I decided to attempt to raise Mary Ann’s blood volume level by giving her injections of vasopressin. I reasoned that, if she improved, I could reasonably suspect that low blood volume was at the root of  her symptoms and might also play an important role in CFS.

Unfortunately, complications with this therapy set in almost immediately. Mary Ann began suffering from “water intoxication,” the main risk of this treatment, since vasopressin causes the body to retain water. The newly expanded blood volume causes a dilution of the salt in the blood and Mary Ann’s blood sodium levels dropped markedly. Upon measuring her blood sodium, I halted the drug therapy immediately.

I was relieved when I determined that Mary Ann had suffered no physical difficulties because of the sharp drop in her blood sodium. In fact, curiously, two days after the therapy was stopped, she began feeling better than she had felt in years. However, the risks that accumulate with water “intoxication” and low blood sodium levels, in my mind, failed to justify the treatment, and we abandoned that particular effort.

I found myself unable to sleep at night thinking about why Mary Ann had felt so much better after her vasopressin infusion, even when it had caused complications. I was, and remain, perplexed by this seeming contradiction. Clearly, low blood volume levels are important and meaningful in some way to our understanding of the mechanisms of CFS, but, I am sorry to report, the puzzle remains unsolved at this date. And, soon enough, Mary Ann was just as ill as she had been prior to the vasopressin treatment.

Then, a wonderful thing happened: she developed a bleeding ulcer. I suspected the problem could be blamed on the large doses of ibuprofen Mary Ann routinely swallowed to control her muscle and joint pain. At any rate, the hemorrhage inside her abdomen caused her so much pain that Mary Ann rapidly found her way to the emergency room of our local hospital. The staff there determined that she was bleeding internally, and they followed standard protocol for such a condition: they gave her a blood transfusion. In fact, they gave her several pints until her stomach quit bleeding, at which point they sent her home. She began keeping a journal the day she came home and called it, “Diary of Lab Rat # 1.”

I always ask my CFS patients to fill out a questionnaire before each visit. I sometimes suspect that they believe these questionnaires, which force them to respond to a great many detailed inquiries about their symptoms and their level of activity, are a kind of punishment. Inevitably, these forms remind them of just how thoroughly rotten they feel. Nevertheless, I have found these questionnaires to be extremely helpful in monitoring their illness. It turns out, in case anyone was wondering, that the secret to interpreting fluctuating energy levels in CFS is in the fine details.

Mary Ann filled out one of these questionnaires the day after her transfusion and wrote that she was “whoogy and very tired.” I have never demanded of Mary Ann that she define “whoogy” for me, mostly because I can pretty well guess by the sound of it. The following day, however, Mary Ann was able to walk through the rooms of her house and even venture outside to her garden. She also discovered that, for the first time in her recent memory, she was not thirsty.

Before her blood transfusion, Mary Ann typically experienced about an hour a day during which she could be upright. A week after the transfusion, however, Mary Ann’s life began to change radically. One morning, she wrote in her lab rat diary, “Did I get healthy blood–or what???” It seemed to her that virtually every symptom of illness had been muted – dramatically. One of the most exciting new developments was her newfound sense of mental clarity, something that CFS sufferers inevitably lose when they become sick. Before falling ill with CFS, Mary Ann had been a crossword puzzle whiz; now she began to work the crosswords again. She felt as if she was opening up all the dusty, long-shuttered cabinets in her memory, and was discovering that although they had been closed for a long time, the contents had remained in tact. She found she could keep her focus on the written page, too. She took up reading after a long hiatus. One evening, she set the newspaper down and realized with wonderment that, for the first time in years, she had read the journal from front to back.

She noted in her diary that she had pulled her grandchildren, all of them squeezed together in a red wagon, down the sidewalk. On the eleventh day after the transfusion, she wrote that she had played baseball with her older grandchildren for the first time. Soon afterward, she and her husband drove 200 miles looking for the perfect pair of bicycles – Mary Ann was anticipating long rides along the country roads. After all, she felt perfectly well. Mary Ann was even ready to do a TV commercial about her hair. One of the oddest symptoms of CFS is the complaint by many patients that they are losing their hair. Women in the most severe episodes of the disease often report they find clumps of hair in their brushes. My patients, women particularly, get annoyed with me over this particular issue, and not only because it’s hard for me to objectively assess this complaint. I rarely consider hair loss to be a pressing concern when there are so many more serious medical matters to face. I suggested to Mary Ann that blood transfusions were not currently the modality of choice to correct thinning hair.

Diary of Lab Rat # 1: “No nightmares like I used to have. I don’t feel ‘sick’ all the time. I’m praying that it will last, but if it doesn’t, I pray that I won’t get depressed. I know that God could heal me in a minute if He wanted, but He’s given me this illness, and now, feeling better, for a purpose. So I guess my job is to do His will and whatever He has in His plan.”

Whenever Mary Ann came to my clinic during her incredible respite from suffering, I was always reminded of the old Mary Ann who had worked in the ICU at the hospital. She was perky; she looked great. For the first time in years I was able to enjoy that wonderful, relaxed sense of comic timing that was her hallmark. It is incredible what CFS can do to a person.

The scientist in me was at war with the clinician in me over Mary Ann’s case. The scientist was insisting that Mary Ann’s metamorphosis could easily be ascribed to the placebo effect. Finally, I had to tell the scientist to stuff a sock in it. Mary Ann’s come-back-kid status had been precipitated by an event – a transfusion for an abdominal hemorrhage – that was virtually an accident. Still, I asked myself again and again: what was the secret of the blood transfusion? What was it telling me about CFS?

I began thinking about other blood-related clues I had observed over the years. People with CFS typically report they feel much worse after lab technicians draw multiple vials of blood from them for diagnostic tests. In addition, I had observed that by administering IV fluids to people with CFS, I could often generate a temporary improvement in their symptoms. Most significantly, I realized, the constellation of symptoms that make up the entity we know as CFS, particularly weakness, dizziness, and difficulty concentrating resemble the symptoms of shock due to blood loss.

Nevertheless, from my experience with Mary Ann, I had learned that simply expanding a patient’s blood volume wasn’t the answer. I have since speculated – but it is only speculation – that the answer might lie in the red blood cells themselves or the blood vessels carrying them. Scientists in Australia and England have suggested that red blood cells of CFS patients are misshapen, and appear to be damaged. They have advanced the hypothesis that the capability of red blood cells to carry oxygen around the body is impaired in CFS sufferers. Maybe the infusion of new red blood cells into Mary Ann’s body was what made the difference. Maybe this really was, as my patient had called it, “healthy blood.” In other words, normal, undamaged red blood cells, coupled with an increase in general blood volume, might explain Mary Ann’s rebound. Mary Ann’s deterioration began six weeks later.

“Day 46,” she wrote in her diary. “Starting to spiral down.” She had to put her crossword puzzles away; her mind was growing foggy and confused. “Fingers keep latching up and dropping and breaking stuff,” she wrote a few days later. On another day, she wrote, “Dizzy if I stand up and I have to hold on to something.” The following day: “It’s been worth it…but if it’s over I have to keep from falling apart.” And finally, “Quietly starting to panic.” She was unable to pull her grandchildren in their wagon.

Months passed. My heart broke whenever Mary Ann came to the office. Searching for a therapy that might help, or at least do no harm, I decided to give her weekly intravenous infusions of a liter, or about a quart, of saline water, the salty, purified water that is titrated to mimic the salt content of our bodies. I offered the therapy to her on the grounds that we might be able to raise her blood volume simply by administering extra fluid to her blood stream. Mary Ann felt a bit better after this treatment, though its good effects lasted just two days. I continue to provide Mary Ann with this treatment on a weekly basis, because it offers her some relief, which happens to be more than any other therapy can offer.

One might ask: why not give Mary Ann with another blood transfusion? The question goes to the heart of clinical medicine. As doctors, we must err on the side of caution. In fact, my profession and the federal government each has a responsibility to protect us all from medical charlatans. Before the government can approve a new treatment for a disease, for instance, scientists must apply for grant money, submit protocols for their experimental therapy to review boards, and those protocols must be approved by these boards. After all this, the therapy must be thoroughly tested on significant numbers of patients, and the results submitted to the government for further review. It’s a good system, and without it, great harm might be done.

Doctors who work each day in the trenches of clinical medicine cannot undertake this kind of research. We would require sizable grants from the government to begin the work, an enormous amount of free time, and a veritable hoard of interns and residents to carry out the study using real patients. Clearly, a small town doc like me, living near the end of the world, cannot test in an appropriately scientific fashion the effect of blood transfusions in CFS. And it’s hard to imagine any medical journal would publish Mary Ann’s case history, because it is merely speculative, even if highly provocative. Sometimes, I feel the only solution for me is to develop multiple personalities or else go mad.

When I am wearing my “scientist” hat, I remain skeptical. When I am in my office, talking to Mary Ann, I sometimes think I’m going to go ballistic over the scientific establishment’s onerous demands for expensive, lengthy, double blind studies. Yet, giving Mary Ann another transfusion cannot be done now, as there is no established protocol for
this treatment in CFS. I’m not just worried about going to jail. It is possible that another transfusion might cause Mary Ann harm. I just don’t know.

In the old days, patients rarely learned very much about whatever disease had laid them low. There were no support groups, no newsletters, no conferences, and no unscientific books like this one. As a result, patients were rarely frustrated about scientific progress in their particular disease. For the most part, they remained blissfully ignorant about new ideas and new developments that could directly impact their destinies. Most especially, patients did not read about crackpot ideas like blood transfusions as a treatment for CFS.

I remain convinced that CFS is a treatable disease. Perhaps it will be impossible to fully reverse CFS once it has a foothold in a patient, but I believe many of the symptoms will be alleviated, once we learn how. It saddens me profoundly to see Mary Ann as she is today. Only our shared faith that CFS may someday be amenable to treatment allows me to shield her from that sadness.
