Between 18 May 2026 and 24 May 2026 the tracker indexed 17 new peer-reviewed studies and 8 clinical-trial updates across 8 post-viral and post-infectious conditions.
Studies tracked = entries across the 8 condition feeds (each feed keeps a rolling window of recent PubMed results); trials tracked = ClinicalTrials.gov records in the current trial snapshot (last run 2026-06-26); biomarkers catalogued = marker entries across all OSMF biomarker atlases.

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a multisystemic illness, commonly associated with dysregulation of the immune system including reduced cytotoxicity of natural killer (NK) cells and post-exertional neuroimmune exhaustion. Previously, transient receptor potential melastatin 3 (TRPM3) ion channel impairment associated with reduced Ca Fluorescence live-cell imaging was used to investigate...
Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a severe multisystem illness marked by post-exertional malaise (PEM), cognitive dysfunction, autonomic disturbance, and impaired physiological resilience. Historically, the absence of validated biomarkers, heterogeneous definitions, and limited investigative capacity have complicated mechanistic interpretation and contributed to the use of psychosocial...
Rheumatoid arthritis (RA) is an autoimmune inflammatory disorder that has seriously affected human health worldwide. This report describes a rare case of herpes infection, secondary to RA, that emerged after coronavirus disease 2019 (COVID-19) infection or vaccination.
The global coronavirus pandemic has led to a quiet wave of a chronic illness referred to as 'Long/Post Covid-19 syndrome' (LC) which bears a notable resemblance to functional-somatic or 'fibromyalgia-type' syndromes, and whose pathophysiology is undetermined. The lack of effective therapies for LC is straining healthcare systems worldwide and causing widespread public health and socioeconomic concerns.
Somatic symptoms of common persistent somatic symptom (PSS) syndromes like irritable bowel syndrome (IBS), chronic fatigue syndrome (CFS), and fibromyalgia (FM) are not fully attributed to well-established biomedical pathological processes. These syndromes are often under-recognized and diagnosis is often delayed.
Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a complex neuroimmunological disorder characterized by disabling symptoms that are often difficult to manage. More recently, in the context of SARS-CoV-2 infection, potential pathophysiological overlaps and disease modulation have been hypothesized.

This study aims to characterize the burden and distinct patterns of chronic overlapping pain conditions (COPCs) multimorbidity in adults with autoimmune rheumatic diseases (ARDs). We analyzed 2008 to 2021 data from the Merative MarketScan Commercial Claims and Encounters Database, identifying 149,742 patients with ARDs (ankylosing spondylitis, psoriatic arthritis, rheumatoid arthritis, Sjögren disease, systemic...
Infection-associated chronic illnesses (IACIs) encompass a spectrum of poorly understood syndromes often marked by significant neurologic and multisystem symptoms following an infectious event. This review focuses on several diseases representative of the IACI spectrum.

Tilt table testing is commonly used to evaluate orthostatic intolerance and syncope and is typically performed with three-lead electrocardiography (ECG) monitoring, which limits P-wave interpretation. A 21-year-old woman with congenitally corrected transposition of the great arteries presented with recurrent tachy-palpitations and near syncope and was presumed to have postural tachycardia syndrome (POTS) after...
Postural orthostatic tachycardia syndrome (POTS) is associated with multiple autonomic symptoms, including gastrointestinal (GI) complaints, and has been linked to insulin resistance. We aimed to explore HbA1c, circulating metabolic hormones (insulin, C-peptide, GIP, GLP-1, glucagon, leptin, and peptide YY) and cortisol, and their associations with hemodynamic parameters and GI symptoms in POTS.
Postural orthostatic tachycardia syndrome (POTS) is a chronic form of orthostatic intolerance that primarily affects female patients. There are scarce data evaluating the long-term outcomes in POTS.
Postural orthostatic tachycardia syndrome (POTS) is a chronic autonomic disorder associated with debilitating symptoms. No medications have been approved for treatment, and patients commonly use off-label medications to treat symptoms.
No new studies this window for: Long COVID, PACVS, Lyme / PTLDS, Gulf War Illness, MCAS.
