Clinical Remission After Therapeutic Apheresis in a Patient Suffering from Long Term Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS): A Case Report

Abstract:

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a debilitating multifactorial illness characterized by profound fatigue persisting for more than six months, post-exertional malaise, cognitive impairments, and a range of systemic symptoms. Until now, no accepted causal treatment regimens have been available; therapeutic options include different approaches, such as alleviation of symptoms and promotion of energy conservation.

In this study, we report the case of a 49-year-old female presented to our center suffering from ME/CFS for more than 15 years, characterised by a strong energy loss and neurological and systemic symptoms; previous therapies remained unsuccessful. Therefore, we decided to perform double-filtration apheresis.

After comprehensive laboratory evaluation, including investigation of persistent viral infections, the patient was treated eight times with double-filtration apheresis within a period of 2 years, which resulted in a remarkable sustained clinical remission and significant improvement in her quality of life. Therefore, we conclude that double-filtration apheresis could be an effective therapeutic tool for the treatment of ME/CFS.

Mitochondrial DNA Missense Mutations ChrMT: 8981A > G and ChrMT: 6268C > T Identified in a Caucasian Female with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) Triggered by the Epstein–Barr Virus

Abstract:

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a multisystem disabling disease with unclear etiology and pathophysiology, whose typical symptoms include prolonged debilitating recovery from fatigue or postexertional malaise (PEM). Disrupted production of adenosine triphosphate (ATP), the intracellular energy that fuels cellular activity, is a cause for fatigue.

Here, we present a long-term case of ME/CFS: a 75-year-old Caucasian female patient, whose symptoms of ME/CFS were clearly triggered by an acute infection of the Epstein–Barr virus 24 years ago (mononucleosis). Before then, the patient was a healthy professional woman.

A recent DNA sequence analysis identified missense variants of mitochondrial respiratory chain enzymes, including ATP6 (ChrMT: 8981A > G; Q152R) and Cox1 (ChrMT: 6268C > T; A122V). Protein subunits ATP6 and Cox1 are encoded by mitochondrial DNA outside of the nucleus: the Cox1 gene encodes subunit 1 of complex IV (CIV: cytochrome c oxidase) and the ATP6 gene encodes subunit A of complex V (CV: ATP synthase). CIV and CV are the last two of five essential enzymes that perform the mitochondrial electron transport respiratory chain reaction to generate ATP.

Further analysis of the blood sample using transmission electron microscopy demonstrated abnormal, circulating, extracellular mitochondria. These results indicate that the patient had dysfunctional mitochondria, which may contribute directly to her major symptoms, including PEM and neurological and cognitive changes. Furthermore, the identified variants of ATP6 (ChrMT: 8981A > G; Q152R) and Cox1 (ChrMT: 6268C > T; A122V), functioning at a later stage of mitochondrial ATP production, may play a role in the abnormality of the patient’s mitochondria and the development of her ME/CFS symptoms.

Longitudinal Cytokine and Multi-Modal Health Data of an Extremely Severe ME/CFS Patient with HSD Reveals Insights into Immunopathology, and Disease Severity

Abstract:

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) presents significant challenges in patient care due to its intricate multisystem nature, comorbidities, and global prevalence. To address these complexities, we employed a comprehensive approach, integrating longitudinal cytokine profiling with extensive clinical, health, textual, pharmaceutical, and nutraceutical data, and performed personalized analyses using AI.

Focusing on an exceptionally severe ME/CFS patient with hypermobility spectrum disorder (HSD) and marginal symptom improvements, our study highlights the dynamic nature of symptoms, severity, triggers, and modifying factors. As part of this study, we introduced an updated platform and two applications, ME-CFSTrackerApp, and LexiTime, facilitating real-time symptom tracking and enhancing physician-patient communication.

Our longitudinal cytokine profiling underscores the significance of Th2-type cytokines and synergistic activities between mast cells and eosinophils, leading to skewing of Th1 toward Th2 immune responses in ME/CFS pathogenesis, especially in cognitive impairment and sensorial intolerance. This suggests a potentially shared underlying mechanism with major comorbidities.

Additionally, our data reveal potential roles of BCL6 and TP53 pathways in ME/CFS etiology and emphasize the importance of investigating low-dose drugs with partial agonist activity in ME/CFS treatment. Our analyses underscore the patient-centered care approach for better healthcare management.

WASF3 disrupts mitochondrial respiration and may mediate exercise intolerance in myalgic encephalomyelitis/chronic fatigue syndrome

Abstract:

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is characterized by various disabling symptoms including exercise intolerance and is diagnosed in the absence of a specific cause, making its clinical management challenging. A better understanding of the molecular mechanism underlying this apparent bioenergetic deficiency state may reveal insights for developing targeted treatment strategies.

We report that overexpression of Wiskott-Aldrich Syndrome Protein Family Member 3 (WASF3), here identified in a 38-y-old woman suffering from long-standing fatigue and exercise intolerance, can disrupt mitochondrial respiratory supercomplex formation and is associated with endoplasmic reticulum (ER) stress.

Increased expression of WASF3 in transgenic mice markedly decreased their treadmill running capacity with concomitantly impaired respiratory supercomplex assembly and reduced complex IV levels in skeletal muscle mitochondria. WASF3 induction by ER stress using endotoxin, well known to be associated with fatigue in humans, also decreased skeletal muscle complex IV levels in mice, while decreasing WASF3 levels by pharmacologic inhibition of ER stress improved mitochondrial function in the cells of the patient with chronic fatigue.

Expanding on our findings, skeletal muscle biopsy samples obtained from a cohort of patients with ME/CFS showed increased WASF3 protein levels and aberrant ER stress activation. In addition to revealing a potential mechanism for the bioenergetic deficiency in ME/CFS, our study may also provide insights into other disorders associated with fatigue such as rheumatic diseases and long COVID.

Individualizing medical treatment in chronic fatigue syndrome/ myalgic encephalomyelitis: Evidence for effective medications and possible relevance to “Long-Hauler Syndrome” in Covid-19 affected patients

Abstract:

Large controlled studies of Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) have shown no effective medical treatment for this disorder. There are individual patients, however, with dramatic responses to some medications.

We report two patients with clear responses to rintatolimod and galantamine characterized by rapid reduction of symptoms on starting treatment and return of symptoms on withdrawal.

As in cancer, CFS/ME is a heterogeneous disorder but unlike most cancers, such as melanoma, breast cancer, and B-cell lymphoma, CFS/ME has no known biological marker that can distinguish between subtypes.

We suggest an approach to medical treatment of CFS/ME that could be utilized by primary caregivers that offer the possibility of more rapid and complete recovery from this debilitating disorder.

Current studies indicate that prolonged symptomatic recovery from infection with Covid-19 (“long hauler syndrome” or PASC, for post-acute sequelae of Covid-19) represents a severe form of CFS/ME and thus may also be amenable to personalized medicine with specific medications.

Oral Minocycline Challenge as a Potential First-Line Therapy for Myalgic Encephalomyelitis and Long Covid-19 Syndrome

Abstract:

Chronic fatigue syndrome characterized by severe disabling fatigue, prolonged post-exertional malaise, and unrefreshing sleep markedly reduces the activities of daily living and impairs the quality of life.

Central nervous system dysfunction associated with myalgic encephalomyelitis (ME) has been postulated as the main cause of chronic fatigue syndrome.

Recently, oral minocycline therapy has been reported to exert favorable therapeutic effects in some patients with ME, especially in the initial stage of the disease, although many patients discontinued treatment in the first few days because of acute adverse effects such as nausea and/or dizziness.

Minocycline appeared to exert a variety of biologic actions against neural inflammation that are independent of their anti-microbial activity, including anti-inflammatory, immunomodulatory, and neuroprotective effects.

In recent years, it has been noted that COVID-19 disease may cause persistent signs and symptoms described as post-COVID syndrome or long COVID, in which the clinical presentation is remarkably similar to those seen in patients with ME.

A wide range of infectious agents have been suggested to trigger the development of ME, and one of such pathogens may be the COVID-19 virus.

Recently, I had a valuable experience of a 22-year-old female patient with a 14-month duration of long COVID who completely recovered from ME-like symptoms after treatment with minocycline. This case suggests that oral minocycline could be an effective first-line therapy for long COVID-19, although a large scale of trial is obviously needed to justify the therapy.

Small heart and single coronary artery in a young patient with chronic fatigue syndrome: a case report

Abstract:

Aims: Chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) is a clinically defined condition reported mostly in adults, characterized by fatigue and unexplained aspecifical symptoms. Patients with CFS/ME frequently have reduced stroke volume with an inverse relation between cardiac output and post-exertional malaise severity. We describe a rare case of a young man affected by CFS/ME, small heart, and anomalous anatomy of left main coronary artery (LMCA).

Methods and results: A 19-year-old Caucasian male referred to our clinic complaining weakness, lack of concentration, and sleepiness. He suffered by CFS/ME, D hypovitaminosis, inflammatory bowel disease, and exocrine pancreas insufficiency.

Blood tests revealed no pathological findings. Faecal exams documented intestinal dysbiosis and low pancreatic elastase.

He was treated with oxygen-ozone rectal insufflations and probiotics. Physical examination was unremarkable.

Electrocardiogram showed normal sinus rhythm. Echocardiogram revealed reduced diameters of the left ventricle (LV), normal aortic root dimensions and, in a five-chamber apical view, a binary structure that seemed to cross the aorta perpendicularly. Cardiac magnetic resonance (CMR) found reduced LV stroke volume (34 ml/m2) and end-diastolic volume (57 ml/m2) together with reduced end-diastolic wall mass (51 g/m2). Right ventricle volumes were reduced too.

In addition, the exam confirmed the anomalous origin of LMCA stemming from the proximal segment of right coronary artery and following a retro-aortic course.

Mechanism of CFS/ME remains unknown, although various factors have been implicated, including immune activation, chronic viral infection, and emotional disorders.

A considerable number of patients affected by CFS has an anatomically small heart. Small heart syndrome, in fact, may contribute to the onset of CFS/ME.

Previous studies hypothesized that clinical manifestations of CMS/ME were caused by reduced venous return, cardiac output, and heart mass, together with decreased arterial oxygen saturation. Single coronary artery is an uncommon congenital anatomic abnormality identified by a single coronary ostium giving rise to all arteries supplying the heart.

Thus, we reported a rare case of a very young man affected by chronic fatigue syndrome and small heart, investigated not only with echocardiogram but also with CMR, not often used in this clinical setting. More, we found an anomalous origin of LMCA. From literature, it’s not reported any cases of a patient including these three rare conditions (CFS/ME, small heart, and single coronary artery).

Conclusions: This case highlights that CFS/ME together with small heart is a condition possible also in young people. More studies and reports could be necessary to better define the association between cardiac congenital anomalies and CFS/ME.

Exploring Symptom Fluctuations and Triggers in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome Using Novel Patient-Centred N-of-1 Observational Designs: A Protocol for a Feasibility and Acceptability Study

Abstract:

Background: Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a chronic condition of unknown aetiology associated with a range of disabling symptoms, including post-exertional malaise, chronic fatigue, musculoskeletal pain, orthostatic intolerance, unrefreshing sleep, and cognitive dysfunction. ME/CFS is a heterogeneous disorder, with significant variation in symptom type and severity between individuals, as well as within individuals over time. The diversity of ME/CFS symptom presentation makes management challenging; treatments supported by data from randomised controlled trials may not work for all individuals due to the variability in experienced symptoms. Studies using quantitative N-of-1 observational designs involve repeated outcome measurements in an individual over time and can generate rigorous individual-specific conclusions about symptom patterns and triggers in individuals with ME/CFS. This study aims to explore the feasibility and acceptability of using novel patient-centred N-of-1 observational designs to explore symptom fluctuations and triggers in ME/CFS at the individual level.

Methods and analysis: Individuals with a medical diagnosis of ME/CFS will be recruited through ME/CFS patient organisations to participate in a series of patient-centred N-of-1 observational studies. Using a wrist-worn electronic diary, participants will complete ecological momentary assessments of fatigue, stress, mood, and cognitive demand, three times per day for a period of 6-12 weeks. Personally relevant symptoms and triggers will also be incorporated into the questionnaire design. Physical activity will be objectively measured via an integrated accelerometer. Feasibility and acceptability outcomes will be assessed including the percentage of diary entries completed, as well as recruitment and retention rate, feasibility of analysing and interpreting the data collected, and participant views about participation elicited via a post-study semi-structured interview.

Discussion: This study will assess the feasibility and acceptability of patient-centred N-of-1 observational studies to assess diseases with complex presentations such as ME/CFS, as well as provide individual-level evidence about fluctuations and triggers of ME/CFS symptoms that may aid self-management.

Case Study Suggests Young People Susceptible To Chronic Fatigue Syndrome After Covid-19

Press Release:

With more adolescents and young adults being treated for COVID-19, clinicians are concerned that these people also will start showing post-COVID — or “long haul” — symptoms from their bouts with the virus. A recent Johns Hopkins Medicine review of three case studies provides some of the first evidence that one serious post-COVID problem may be myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), the complex, multisystem disorder previously known as chronic fatigue syndrome.

The findings were published April 29 in the journal Frontiers in Medicine.

“In the three patients studied — all of whom had confirmed or highly probable COVID-19 infections early in the pandemic — we observed ME/CFS-like symptoms within the first two weeks of illness,” says Peter Rowe, M.D., director of the Chronic Fatigue Clinic at Johns Hopkins Children’s Center and professor of pediatrics at the Johns Hopkins University School of Medicine. “At six months following their illness, all three still met the criteria for being diagnosed with ME/CFS.”

In a recent report, the U.S. Centers for Disease Control and Prevention (CDC) noted that U.S. hospitals are seeing more adolescents and young adults admitted with COVID-19 as more contagious variants of SARS-CoV-2 — the virus that causes the disease — spread. The agency believes that the youthful case surge may be the result of those ages 10 to 24 being among the last prioritized to get the coronavirus vaccines, and the fact that many who are eligible have yet to receive their shots. Also, the CDC says, this group is more likely to be involved in high-risk behaviors such as playing close-contact sports and going out to bars.

The three patients evaluated in the recent study were a 19-year-old man and two women, ages 22 and 30, whose COVID-19 symptoms began between April and June 2020, and who were referred to the Chronic Fatigue Clinic between August and October of the same year. Symptoms of orthostatic intolerance — a group of clinical conditions that includes fatigue, lightheadedness and difficulty concentrating, and are linked with greater than 90% of the people with ME/CFS — were prominent in all three from the outset of their COVID-19 illness.

A six-month post-COVID symptom onset examination, including evaluations of movement, neurological function and continued orthostatic intolerance, was conducted on each of the patients to determine if ME/CFS could be diagnosed. All three easily met the criteria.

Interestingly, Rowe says, all three patients had relatively mild COVID-19 respiratory symptoms and none required hospitalization, yet it appears to have translated into the more serious secondary problem of ME/CFS for them all.

“This finding is consistent with previous studies in older patients with COVID-19 who showed persistent fatigue months after infection, regardless of the severity of the initial infection,” he explains. “This raises the question of how many ME/CFS cases before the COVID-19 pandemic might have been due to mild, subclinical or asymptomatic viral infections [such as Epstein-Barr virus or human herpesvirus 6], including cases in adolescents, young adults and older people.”

Rowe and his colleagues feel that further research is needed to define the biological mechanism by which ME/CFS arises from COVID-19, and then use that insight to develop treatment strategies that can return patients with post-COVID ME/CFS back to their previous quality of life.

Rowe is available for interviews.

Three Cases of Severe ME/CFS in Adults

Abstract:

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a complex, only partially understood multi-system disease whose onset and severity vary widely. Symptoms include overwhelming fatigue, post-exertional malaise, sleep disruptions, gastrointestinal issues, headaches, orthostatic intolerance, cognitive impairment, etc. ME/CFS is a physiological disease with an onset often triggered by a viral or bacterial infection, and sometimes by toxins. Some patients have a mild case and are able to function nearly on a par with healthy individuals, while others are moderately ill and still others are severely, or even, very severely ill. The cohort of moderately to very severely ill is often housebound or bedbound, has lost employment or career, and has engaged in a long, and often futile, search for treatment and relief. Here, we present three case studies, one each of a moderately ill, a severely ill, and a very severely ill person, to demonstrate the complexity of the disease, the suffering of these patients, and what health care providers can do to help.
