This study describes two cases where patients were initially thought to have acute leukemia based on blood tests, but they actually had Epstein-Barr virus (EBV) infections instead. One patient had infectious mononucleosis, and the other had a rare EBV-related immune condition. The study shows that EBV can sometimes look like leukemia under a microscope, which can lead to misdiagnosis.
This study is relevant to ME/CFS because EBV is suspected by some researchers as a potential trigger or cofactor in ME/CFS development, though causality remains unproven. Understanding how EBV manifests clinically and how it can be confused with other serious conditions helps clarify the complex relationship between viral infections and post-viral illnesses like ME/CFS.
This case report does not prove that EBV causes ME/CFS or even establish causality in any condition. The authors acknowledge that while EBV 'has been found to be associated with' ME/CFS and other diseases, 'causality still remains an issue of debate.' Case reports cannot establish prevalence, incidence, or causal mechanisms—they describe rare presentations. The study also does not clarify why some EBV infections lead to ME/CFS while others do not.
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 →
