Differential Characteristics and Comparison Between Long-COVID Syndrome and Myalgic Encephalomyelitis/Chronic Fatigue...

Area of Science:

• Neuroscience
• Immunology
• Infectious Diseases

Background:

• Long-COVID and ME/CFS are debilitating conditions with overlapping symptoms such as fatigue, post-exertional malaise, cognitive impairment, and autonomic dysfunction.
• While ME/CFS often follows viral infections, Long-COVID is specifically linked to SARS-CoV-2 infection, presenting both shared and unique clinical features.

Purpose of the Study:

• To conduct a comprehensive review comparing the clinical presentations, pathophysiologies, and treatment strategies of Long-COVID and ME/CFS.
• To identify common and distinct mechanisms underlying these conditions to inform the development of targeted therapies.

Main Methods:

• Comprehensive literature searches across online databases.
• Comparative analysis of clinical manifestations, underlying biological mechanisms, and therapeutic interventions.

Main Results:

• Both Long-COVID and ME/CFS appear to stem from multifactorial causes including viral persistence, immune dysregulation, endothelial dysfunction, and autoimmunity, though their precise roles are not fully elucidated.
• Symptom management approaches are similar, with cognitive behavioral therapy showing success and graded exercise therapy being a subject of debate, emphasizing individualized pacing and multidisciplinary rehabilitation.

Conclusions:

• Identifying shared and exclusive pathogenic mechanisms is crucial for developing effective therapies for both Long-COVID and ME/CFS.
• Further research into immune dysfunction is essential for advancing disease understanding, diagnostics, and therapeutic strategies.
