In East and Southern Africa, where 5% to 10% have chronic hepatitis B virus (HBV) infection, incidence of human immunodeficiency virus (HIV) infection remains unacceptably high. This introduces challenges and opportunities for implementation of HBV care and treatment. We now describe new HIV diagnoses made within an HBV monoinfection cohort in Zambia and their relevance to broader HBV policy implementation.
People who inject drugs are at high risk of acquiring hepatitis B (HBV), hepatitis C (HCV), and human immunodeficiency virus (HIV) due to risky injection and sexual practices. The objective of this study is to investigate the epidemiology of HIV, hepatitis B, and hepatitis C, and co-infection of these viruses among people who inject drugs in Zanzibar, Tanzania.
Predominance of Hepatitis B Virus Genotype A Among Treated HIV Infected Patients Experiencing High Hepatitis B Virus Drug Resistance in Nairobi, Kenya
Hepatitis B virus (HBV)–HIV coinfections are becoming common with information on HBV genetic diversity and drug resistance still remaining elusive. To evaluate the HBV genetic diversity and drug resistance-associated mutations among drug-experienced HIV patients, the genetic analysis of the partial HBV-pol-reverse trancriptase gene was successfully sequenced from 13 samples. Analysis of the sequences showed that all (11) the sequences belonged to genotype A. Nucleos(t)ide drug resistance mutations were found in 6 patients.
Hepatitis B incidence and prevention with antiretroviral therapy among HIV-positive individuals in Uganda
Objective: Antiretroviral therapy (ART) may interfere with replication of hepatitis B virus (HBV), raising the hypothesis that HBV infection might be prevented by ART. We investigated the incidence and risk factors associated with HBV among HIV-infected adults in Rakai, Uganda.
