AI Article Synopsis
- In Africa, HIV coinfection with hepatitis B (HBV) and hepatitis C (HCV) is a significant public health issue, yet data on its epidemiology and case fatality rates are limited.
- A systematic review of 4388 articles identified 314 studies, revealing a 4.4% case fatality rate for HBV among people living with HIV (PLHIV) and various prevalence rates for HBV (10.5%), HCV (5.4%), and their coinfection (0.7%).
- The findings highlight the need for targeted public health efforts to address the complex interplay of these infections in Africa, given the observed variability and challenges in data reporting.
Article Abstract
Introduction: Due to their common routes of transmission, human immunodeficiency virus (HIV) coinfection with hepatitis B virus (HBV) and/or hepatitis C virus (HCV) has become a major public health problem worldwide, particularly in Africa, where these viruses are endemic. Few systematic reviews report the epidemiological data of HBV and/or HCV coinfection with HIV in Africa, and none provided data on the case fatality rate (CFR) associated with this coinfection. This study was conducted to investigate the prevalence and case fatality rate of HBV and/or HCV infections among people living with human immunodeficiency virus (PLHIV) in Africa.
Methods: We conducted a systematic review of published articles in PubMed, Web of Science, African Journal Online, and African Index Medicus up to January 2022. Manual searches of references from retrieved articles and grey literature were also performed. The meta-analysis was performed using a random-effects model. Sources of heterogeneity were investigated using subgroup analysis, while funnel plots and Egger tests were performed to assess publication bias.
Results: Of the 4388 articles retrieved from the databases, 314 studies met all the inclusion criteria. The overall HBV case fatality rate estimate was 4.4% (95% CI; 0.7-10.3). The overall seroprevalences of HBV infection, HCV infection, and HBV/HCV coinfection in PLHIV were 10.5% [95% CI = 9.6-11.3], 5.4% [95% CI = 4.6-6.2], and 0.7% [95% CI = 0.3-1.0], respectively. The pooled seroprevalences of current HBsAg, current HBeAg, and acute HBV infection among PLHIV were 10.7% [95% CI = 9.8-11.6], 7.0% [95% CI = 4.7-9.7], and 3.6% [95% CI = 0.0-11.0], respectively. Based on HBV-DNA and HCV-RNA detection, the seroprevalences of HBV and HCV infection in PLHIV were 17.1% [95% CI = 11.5-23.7] and 2.5% [95% CI = 0.9-4.6], respectively. Subgroup analysis showed substantial heterogeneity.
Conclusions: In Africa, the prevalence of hepatotropic viruses, particularly HBV and HCV, is high in PLHIV, which increases the case fatality rate. African public health programs should emphasize the need to apply and comply with WHO guidelines on viral hepatitis screening and treatment in HIV-coinfected patients.

No cost-effectiveness information of preventive strategies for mother-to-child transmission (MTCT) of hepatitis B virus (HBV) has existed for policy decision making. This study aimed to compare the cost-effectiveness of alternative strategies to prevent MTCT of HBV in Vietnam. Cost-utility analysis using a hybrid decision-tree and Markov model were performed from healthcare system and societal perspectives.

Following a gluten-free diet (GFD) is known as the main effective therapy available for celiac disease (CD) patients, which in some cases is not enough to heal all patients presentations completely. Accordingly, emerging researchers have focused on finding novel therapeutic/preventive strategies for this disorder. Moreover, previous studies have shown that celiac patients, especially untreated subjects, are at increased risk of developing viral and bacterial infections, which can become a challenge for the clinician.

Background: Hepatitis B virus (HBV) infection remains a major health challenge in Nigeria, with high prevalence rates among pregnant women. The prevalence of overt and occult hepatitis B infection (HBI and HBI) among pregnant women was investigated to understand the burden and associated risk factors in this population.
Methods: A cross-sectional study was conducted among 200 pregnant women.
