This study looked at a hormone called DHEAS in patients with a liver disease called primary biliary cirrhosis (PBC). The researchers found that patients with PBC who experienced fatigue had lower DHEAS levels than healthy people, and the lower the DHEAS, the more severe their fatigue was. This suggests that low DHEAS might be one reason why some liver patients feel exhausted, and raising DHEAS levels might help reduce their fatigue.
This study is relevant to ME/CFS because it identifies DHEAS deficiency as a potential biological marker associated with fatigue severity independent of underlying organ disease. The findings suggest that neuroactive steroid dysregulation may be a common fatigue mechanism across different conditions, opening avenues for potential therapeutic intervention that could apply beyond PBC to other fatigue disorders including ME/CFS.
This study does not prove that low DHEAS causes fatigue or that DHEAS supplementation will improve symptoms, only that an association exists. The study was conducted in PBC patients with concurrent liver disease, so findings may not directly translate to ME/CFS patients without liver pathology. The small sample size and cross-sectional design prevent definitive causal conclusions.
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 →
