HBV Dominance Is Associated With a Distinct Inflammatory Milieu in HBV/HCV Coinfection
Journal of Viral Hepatitis, Volume 32, Issue 11, November 2025.ABSTRACT Hepatitis B (HBV) and C (HCV) virus coinfection is linked to a higher risk of cirrhosis and hepatocellular carcinoma (HCC) compared to monoinfection. Despite this, data are limited, and further investigation is needed to understand the underlying mechanisms.

Successful switch to tenofovir after suboptimal response to entecavir in an immunocompromised patient with chronic hepatitis B and without genotypic hepatitis B virus resistance [PDF]
, 2011 We report a case of an immunocompromised patient affected by chronic hepatitis B virus (HBV) with high basal HBV viremia (>8 log(10) IU/ml) who failed an entecavir regimen, despite the absence of primary or secondary drug resistance mutations.

Revaccination Response and Lack of Hepatitis B Reactivation After HCT for Sickle Cell Disease
Transplant Infectious Disease, Volume 27, Issue 6, November/December 2025.At baseline, 55% of sickle cell patients showed HBV immunity, and 93% received post HCT revaccination, with 89% completing the series. Between Years 1–2, 67.5% of vaccinated patients had rising anti HBs titers. No HBV reactivation occurred, though nonresponders under heavy immunosuppression need further study.
