This review examines how hepatitis C virus (HCV) can affect parts of the body beyond the liver. The authors discuss various conditions linked to HCV infection, including chronic fatigue, dry mouth and eyes, diabetes, and certain blood cancers. They note that while these connections are documented, scientists still don't fully understand the mechanisms behind them.
This study is relevant to ME/CFS patients because it documents chronic fatigue syndrome as a recognized extrahepatic manifestation of HCV infection, demonstrating that viral infections can cause prolonged fatigue conditions. Understanding viral-associated fatigue syndromes may help identify common pathophysiological pathways and inform treatment strategies applicable to multiple fatigue-related illnesses.
This review does not establish causality between HCV and chronic fatigue syndrome, nor does it clarify whether HCV-associated fatigue shares mechanisms with idiopathic ME/CFS. The article is a narrative review without systematic methodology, so it cannot quantify prevalence or establish definitive risk factors for any EHM.
About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
