ME/CFS: The Importance of a Thorough Differential Diagnosis

By

ME/CFS is often used as a broad diagnostic category, but in some cases underlying medical conditions may remain partially investigated or overlooked. 
 

Commonly associated factors may include viral infections, post-exertional malaise (PEM), postural orthostatic tachycardia syndrome (POTS), fibromyalgia-like pain, immune or vascular abnormalities, neuroinflammation and/or encephalitis, possible glymphatic or lymphatic system dysfunction, and possible syringomyelia.

Further research, including head and torso MRI imaging, comprehensive hematological and endocrinological testing, and evaluation of genetic or inherited markers, may help clarify underlying mechanisms and improve diagnostic understanding.

At the same time, important conditions such as thyroid disease, adrenal insufficiency, lupus, hemophilia or other bleeding disorders, infections, vasculitis, and other systemic illnesses may not always be fully excluded and can coexist with or contribute to symptoms.

The examples listed here are intended only to highlight a small number of potentially overlooked, symptom-related, and undiagnosed conditions that may contribute to complex clinical presentations.

A thorough differential diagnosis remains essential before concluding that all symptoms are solely attributable to ME/CFS.

Schnitzler Syndrome: A Rare Autoinflammatory Disorder

By
Schnitzler syndrome is a rare, chronic autoinflammatory disease characterized by chronic urticaria (hives), recurrent fever, joint pain, and monoclonal gammopathy (abnormal proteins in the blood). First described by Dr. Liliane Schnitzler in 1972 , this condition is often misdiagnosed, leading to years of untreated symptoms before a correct diagnosis is made. The case report, " A 58-Year-Old Woman With Urticaria, Fever, and Joint Pain " , describes a case that closely aligns with my own experience with this challenging disorder. Key Features of Schnitzler Syndrome Schnitzler syndrome presents with a characteristic set of symptoms, though not all patients experience them in the same way: Chronic Urticaria (Hives) – Persistent, non-itchy or mildly itchy red patches that do not respond to antihistamines. Monoclonal Gammopathy (IgM or IgG type) – Abnormal monoclonal immunoglobulin detected in the blood (most commonly IgM ). Recurrent Fever – Unexplained fever episodes, often...

Acute Flaccid Myelitis (AFM): Understanding the “Polio-like” Illness Affecting the Spinal Cord

By
Acute flaccid myelitis (AFM) is a rare but serious neurological disorder that primarily affects children and results in sudden weakness or paralysis in the limbs. Often referred to as a “polio-like” illness, AFM has drawn growing attention over the past decade due to its similarities with poliomyelitis and its seasonal spikes in reported cases. While AFM remains uncommon, its potential severity—and the uncertainty surrounding its causes—make it an important condition for clinicians, parents, and public health officials to understand. What Is Acute Flaccid Myelitis? AFM is a condition that affects the gray matter of the spinal cord , where it damages motor neurons responsible for muscle movement. This leads to acute, flaccid paralysis , meaning muscles become limp and weak, often without warning. The condition can progress rapidly, and in some cases, the weakness can become long-lasting or even permanent. Although its symptoms resemble those of poliovirus infection, AFM is not cau...

Dysferlin Protein: Key Roles, Genetic Locations

By
Image
The purpose of this article is to share and discuss the details of a new discovery, which is highlighted within: CRISPR-Cas9: A Breakthrough Tool to Repair the DYSF Gene The dysferlin protein plays an essential role in maintaining the integrity of muscle cell membranes, particularly in tissues that endure significant mechanical stress, such as skeletal and cardiac muscles . Encoded by the DYSF gene , dysferlin is indispensable for repairing damaged cell membranes after injury caused by muscle contraction or external forces. This article explores the main locations where dysferlin is produced, its role in muscle repair, and supportive nutritional and therapeutic strategies for individuals with dysferlin deficiency, such as those affected by dysferlinopathies (e.g., Limb-Girdle Muscular Dystrophy Type 2B or Miyoshi Myopathy). Currently, there is no definitive answer as to why the severity of dysferlin protein expression or depletion varies. Do pathogens play a role in the methylation o...

Very Long-Chain Fatty Acids (VLCFAs) X-ALD and Spinal Muscular Atrophy (SMA): Exploring the Connection

By
Image
Introduction: White Brain Matter, VLCFAs, and X-ALD X-linked Adrenoleukodystrophy (X-ALD) is a rare inherited metabolic disorder and a major cause of progressive neurodegeneration in children—sometimes referred to as “childhood dementia.” Across related conditions, prevalence can range from approximately 1 in 2,000 to 1 in 500,000 newborns. Among its forms, childhood cerebral X-ALD is the most severe, marked by rapid inflammatory demyelination in the brain and often fatal outcomes if not treated early. At the core of X-ALD is a disruption in the metabolism of Very Long-Chain Fatty Acids (VLCFAs). Normally, these fatty acids are broken down in peroxisomes—specialized structures within cells that help maintain metabolic balance. In X-ALD, a mutation in the ABCD1 gene impairs this function, causing VLCFAs to accumulate, particularly in the white matter of the brain, spinal cord, and adrenal glands. This accumulation leads to demyelination, adrenal insufficiency (Addison’s disease), an...

Is ME CFS connected to Spinal Muscular Atrophy (SMA) or Post Polio?

By
Today, I understand why Spinal Muscular Atrophy (SMA) received little attention, particularly in the mid-50s. This complex and debilitating genetic illness was poorly understood, and patients' symptoms were often minimized or even dismissed. For more information, please visit the Spinal Muscular Atrophy (SMA) page on MalaCards . Even now, many neurologists lack detailed knowledge of SMA, and comprehensive examinations mentioned in research are rarely pursued. In 2008, while investigating permanent adrenal insufficiency, an MRI ordered by my endocrinologist unexpectedly revealed Chiari Malformation II. However, surgery in 2009 brought no improvement. In 2010, a DNA test showed a genetic marker in the ACTN3 gene: https://www.malacards.org/search/results?q=ACTN3%20gene%20and%20Spinal%20Muscular%20Atrophy%20(SMA) A 2015 MRI revealed ankylosing spondylitis, multiple Tarlov cysts, stenosis at L4 and L5, spinal canal narrowing, and widespread degenerative changes. Surgery on L4 and L5 ...

Polio and Post-Polio Syndrome (PPS): Summary and Key Insights

By
Image
  Abstract To investigate the possible role of poliovirus (PV) infection in the development of Post-Polio Syndrome (PPS), researchers studied serum, cerebrospinal fluid (CSF), peripheral blood lymphocytes, and muscle tissue from 47 PPS patients. Elevated IgM antibodies against poliovirus were identified in a subset of patients, with titers reaching 1:250 compared with less than 1:50 in healthy individuals and disease controls. Using polymerase chain reaction (PCR) techniques targeting the poliovirus replicase gene, PV RNA sequences were detected in peripheral blood lymphocytes from 7 of 37 patients and in the CSF of 4 of 40 patients, while no viral sequences were detected in controls. Sequencing confirmed a 99.3% homology with poliovirus type 1. These findings suggest that some PPS patients may exhibit an ongoing immune response to poliovirus antigens. The detection of poliovirus RNA raises the possibility of persistent mutated virus or defective viral particles. However, the signi...

Update: New Research Builds on Previous Findings Cytokine Storms in COVID-19, Hemophagocytic Lymphohistiocytosis, and CAR-T Therapy https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2832234?utm_source=silverchair&utm_medium=email&utm_campaign=article_alert-jamanetworkopen&utm_content=wklyforyou&utm_term=040925&adv= Conclusions: This recent cohort study builds upon earlier work by identifying COVID-related cytokine storm (COVID-CS) through common inflammation markers and comparing it with two other cytokine storm (CS) conditions: malignancy-associated hemophagocytic lymphohistiocytosis (MN-HLH) and CAR-T–associated cytokine release syndrome (CAR-T CRS) . Among the three groups, patients treated with CAR-T therapy showed the highest survival rates , in contrast to those with COVID-CS and MN-HLH. Interestingly, the study found that CAR-T CRS and COVID-CS share similar cytokine activation pathways , suggesting a comparable immune response mechanism. In c...

The Impact of Acids on Muscular and Vascular Systems: Potential Negative Outcomes

By
This is ongoing research, and updates will be included as soon as they become available. Acids, whether from external sources (like industrial chemicals) or internal imbalances (such as metabolic disorders), can have profound effects on both the muscular and vascular systems.   Exposure to strong acids or acid imbalances in the body can disrupt cellular function, cause tissue damage, and lead to systemic health problems. This article explores how acids can negatively impact muscular and vascular health, with an emphasis on both external exposure to corrosive acids and internal acid imbalances caused by metabolic disorders or genetic conditions. Since not everyone is affected by ME/CFS or COVID, it could be beneficial to test for genetic predispositions, such as amino acids, particularly fatty acids. 1. External Acid Exposure and Its Effects on Muscular and Vascular Systems 1.1. Muscular Effects Muscle tissue is highly sensitive to changes in pH, and exposure to strong acids ca...

Introduction to Adenosine and Tachycardia

By
What is Adenosine? Adenosine is a chemical found in human cells, existing in three forms: adenosine, adenosine monophosphate (AMP), and adenosine triphosphate (ATP). Adenosine is a chemical found in the body that plays many roles, including influencing heart rate and promoting sleep and relaxation. It is also used as a medication to manage certain types of tachycardia, particularly supraventricular tachycardia. Adenosine works by slowing the heart rate through its action on the cardiac tissue. Adenosine production in the body occurs through multiple pathways: Phosphorylation of Adenine: Adenine can be directly phosphorylated to form AMP (adenosine monophosphate), which is then converted to ATP, ADP, and finally adenosine through dephosphorylation reactions. Breakdown of ATP: Adenosine is primarily formed in the body through the breakdown of ATP, which releases energy. ATP can be dephosphorylated stepwise through the action of various enzymes: ATP is first converted to ADP (adeno...
