Impact of Lamivudine-Based Antiretroviral Treatment on Hepatitis B Viremia in HIV-Coinfected South Africans. Viruses 2020; 12:v12060634. [PMID: 32545313 PMCID: PMC7354521 DOI: 10.3390/v12060634] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2020] [Revised: 05/28/2020] [Accepted: 06/08/2020] [Indexed: 12/12/2022] Open
Abstract
This prospective study investigated the impact of lamivudine-containing antiretroviral therapy (ART) on HIV-positive patients in South Africa with baseline hepatitis B virus (HBV) infection. Follow-up samples from 56 HBV/HIV co-infected patients, 25 with occult HBV infection (OBI) and 31 with chronic HBV infection (CHB), were available for analysis. HBV viral loads were quantified at 6, 12, 18, and 24 months post-ART initiation by the COBAS TaqMan HBV Test 48 assay, and the HBV polymerase gene was amplified with an in-house nested polymerase chain reaction assay. During 24 months of lamivudine-based ART, 6 of 8 (75%) OBI and 4 of 6 (67%) CHB patients achieved undetectable levels of HBV DNA, while 2 patients had persistent HBV DNA levels ≥ 2 × 105 despite lamivudine-based ART for 24 months. HIV viremia was undetectable in all patients at 12 months, suggesting high adherence to ART. Several lamivudine-associated HBV resistance mutations, including L180M, A181T, M204I, and M204V, were observed. Sequence analysis also revealed a rare genotype G infection. While resource-limited settings may use lamivudine-based ART because of availability and low cost, antivirals with dual therapy against HBV and HIV (e.g., lamivudine and tenofovir) should always be recommended with the regular monitoring of HBV viremia levels.

Abstract
Liver diseases that are caused by the hepatitis B virus (HBV) and hepatitis C virus (HCV), including cirrhosis and hepatocellular carcinoma (HCC), have become increasingly important in patients infected with the human immunodeficiency virus (HIV) as their life expectancy is getting longer with successful anti-HIV therapy. Due to their shared transmission routes, dual infection by HIV and HBV or HIV and HCV, and triple infection by all three viruses are fairly common and affect millions of people worldwide. Whereas the immunodeficiency caused by HIV enhances the likelihood of HBV and HCV persistence, hepatotoxicity associated with anti-HIV therapy can worsen the liver diseases associated with HBV or HCV persistence. Evidence suggests HIV infection increases the risk of HBV- or HCV-associated HCC risk although the precise mechanisms of enhanced hepatocarcinogenesis remain to be fully elucidated. Recent success in curing HCV infection, and the availability of therapeutic options effective in long-term suppression of both HIV and HBV replication, bring hope, fortunately, to those who are coinfected but also highlight the need for judicious selection of antiviral therapies.

Abstract
Epidemiology: incidence and prevalence:
About 5% of the world’s population has chronic hepatitis B virus (HBV)
infection, and nearly 25% of carriers develop chronic hepatitis, cirrhosis, and
hepatocellular carcinoma (HCC). The prevalence of chronic HBV infection in human
immunodeficiency virus (HIV)-infected individuals is 5%-15%; HIV/HBV coinfected
individuals have a higher level of HBV replication, with higher rates of
chronicity, reactivation, occult infection, and HCC than individuals with HBV
only. The prevalence of HBV genotype A is significantly higher among men who
have sex with men (MSM), compared with the rest of the population.
Molecular mechanisms of infection, pathology, and
symptomatology: HBV replication begins with entry into the
hepatocyte. Sodium taurocholate cotransporting polypeptide was identified in
2012 as the entry receptor of HBV. Although chronic hepatitis B develops slowly,
HIV/HBV coinfected individuals show more rapid progression to cirrhosis and HCC.
Transmission and protection: The most common sources
of HBV infection are body fluids. Hepatitis B (HB) vaccination is recommended
for all children and adolescents, and all unvaccinated adults at risk for HBV
infection (sexually active individuals such as MSM, individuals with
occupational risk, and immunosuppressed individuals). Although HB vaccination
can prevent clinical infections (hepatitis), it cannot prevent 100% of
subclinical infections. Treatment and curability:
The goal of treatment is reducing the risk of complications
(cirrhosis and HCC). Pegylated interferon alfa and nucleos(t)ide analogues (NAs)
are the current treatments for chronic HBV infection. NAs have improved the
outcomes of patients with cirrhosis and HCC, and decreased the incidence of
acute liver failure.

Evidence of susceptibility to lamivudine-based HAART and genetic stability of hepatitis B virus (HBV) in HIV co-infected patients: A South African longitudinal HBV whole genome study. INFECTION GENETICS AND EVOLUTION 2016; 43:232-8. [PMID: 27245151 DOI: 10.1016/j.meegid.2016.05.035] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/02/2016] [Revised: 05/09/2016] [Accepted: 05/25/2016] [Indexed: 01/04/2023]
Abstract
BACKGROUND Reports on the concomitant impact of HIV co-infection and long term highly active anti-retroviral therapy (HAART) on the genetic stability and molecular evolution of HBV are limited in sub-Saharan Africa. MATERIALS AND METHODS This retrospective study investigated the molecular evolution of chronic HBV in HIV co-infected patients on lamivudine (3TC)-based HAART over a 5year period. Four HIV co-infected patients, consecutively recruited and followed-up, were screened for hepatitis B serological markers, and their viral loads determined. The HBV genome was amplified from longitudinal samples and characterized by Bayesian inference, mutational analysis, and identification of immune selection pressure. RESULTS All patients exhibited persistent chronic HBV infection at baseline, as well as over the course of follow-up despite exposure to 3TC-based HAART. The polymerase gene in all isolates was relatively variable prior to HAART initiation at baseline and during the course of follow-up, although primary drug resistance mutations were not detected. All but one patient were infected with HBV subgenotype A1. The divergence rates between baseline and the last follow-up sequences ranged from 0 to 2.0×10(-3) substitutions per site per year (s/s/y). Positive selection pressure was evident within the surface and core genes. CONCLUSION Despite persistent HBV infection in the HIV co-infected patients exposed to long term 3TC-based HAART, the molecular evolution of HBV over a 5year period was unremarkable. In addition, HBV exhibited minimal genetic variability overtime.
