Long-term Hepatitis B and Liver Outcomes Among Adults Taking Tenofovir-Containing Antiretroviral Therapy for HBV/HIV Coinfection in Zambia. Clin Infect Dis 2024; 78:1583-1590.

Abstract
BACKGROUND Long-term outcomes of tenofovir-containing antiretroviral therapy (ART) for hepatitis B virus (HBV)/human immunodeficiency virus (HIV) coinfection were evaluated in Zambia. METHODS A prospective cohort of adults with HIV and hepatitis B surface antigen (HBsAg)-positivity was enrolled at ART initiation. On tenofovir-containing ART, we ascertained HBV viral load (VL) non-suppression, alanine aminotransferase (ALT) elevation, serologic end-points, progression of liver fibrosis based on elastography, and hepatocellular carcinoma (HCC) incidence. We also described a subgroup (low HBV VL and no/minimal fibrosis at baseline) that, under current international guidelines, would not have been treated in the absence of their HIV infection. RESULTS Among 289 participants at ART start, median age was 34 years, 40.1% were women, median CD4 count was 191 cells/mm3, 44.2% were hepatitis B e antigen-positive, and 28.4% had liver fibrosis/cirrhosis. Over median 5.91 years of ART, 13.6% developed HBV viral non-suppression, which was associated with advanced HIV disease. ALT elevation on ART was linked with HBV VL non-suppression. Regression of fibrosis and cirrhosis were common, progression to cirrhosis was absent, and no cases of HCC were ascertained. HBsAg seroclearance was 9.4% at 2 and 15.4% at 5 years, with higher rates among patients with low baseline HBV replication markers. CONCLUSIONS Reassuring long-term liver outcomes were ascertained during tenofovir-based ART for HBV/HIV coinfection in Zambia. Higher than expected HBsAg seroclearance during ART underscores the need to include people with HIV in HBV cure research.

Systematic review and individual-patient-data meta-analysis of non-invasive fibrosis markers for chronic hepatitis B in Africa. Nat Commun 2023; 14:45. [PMID: 36596805 PMCID: PMC9810658 DOI: 10.1038/s41467-022-35729-w] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2022] [Accepted: 12/20/2022] [Indexed: 01/05/2023] Open
Abstract
In sub-Saharan Africa, simple biomarkers of liver fibrosis are needed to scale-up hepatitis B treatment. We conducted an individual participant data meta-analysis of 3,548 chronic hepatitis B patients living in eight sub-Saharan African countries to assess the World Health Organization-recommended aspartate aminotransferase-to-platelet ratio index and two other fibrosis biomarkers using a Bayesian bivariate model. Transient elastography was used as a reference test with liver stiffness measurement thresholds at 7.9 and 12.2kPa indicating significant fibrosis and cirrhosis, respectively. At the World Health Organization-recommended cirrhosis threshold (>2.0), aspartate aminotransferase-to-platelet ratio index had sensitivity (95% credible interval) of only 16.5% (12.5-20.5). We identified an optimised aspartate aminotransferase-to-platelet ratio index rule-in threshold (>0.65) for liver stiffness measurement >12.2kPa with sensitivity and specificity of 56.2% (50.5-62.2) and 90.0% (89.0-91.0), and an optimised rule-out threshold (<0.36) with sensitivity and specificity of 80.6% (76.1-85.1) and 64.3% (62.8-65.8). Here we show that the World Health Organization-recommended aspartate aminotransferase-to-platelet ratio index threshold is inappropriately high in sub-Saharan Africa; improved rule-in and rule-out thresholds can optimise treatment recommendations in this setting.
