AI Article Synopsis

  • This study examined the prevalence and genotypic distribution of Hepatitis B virus (HBV) among HIV-infected individuals in Benin City, Nigeria, as no previous research has focused on this topic in the region.
  • A total of 564 HIV-positive and 250 HIV-negative participants were tested, and the findings showed that HIV status did not significantly influence HBV infection rates, with slightly higher rates in HIV-infected individuals.
  • All confirmed HBV infections in HIV patients were identified as HBV genotype E, which is a novel strain not previously associated with other HBV genotype E groups in Nigeria.

Article Abstract

Objective: Hepatitis B virus (HBV) is not uncommon among persons infected with human immunodeficiency virus (HIV). Severity of HBV infection and treatment outcome are associated with specific HBV genotypes. No study has reported the types of HBV genotypes circulating among HIV-infected subjects in Nigeria. This study was designed to determine the prevalence of HBV, as well as its genotypic distribution among HIV-infected subjects in Benin City, Nigeria.

Methods: Whole blood was collected from a total of 564 HIV-infected and 250 apparently healthy HIV-negative subjects. Serodiagnosis of HBV infection was done using an immunochromatographic kit. Detection of HBV-DNA and sequencing of amplicons were done using standard molecular techniques.

Results: HIV status was not significantly associated with HBV seroinfection (HIV vs. non-HIV: 4.6% vs. 4.0%; odds ratio = 1.168, 95% confidence interval = 0.550, 2.444, and P = 0.854). HIV-infected subjects were observed to have an insignificantly (P = 0.645) higher prevalence of true HBV infection than their non-HIV-infected counterparts (HIV positive vs. HIV negative: 23.1% vs. 10.0%). All patients with true HBV infection were found to harbor HBV genotype E, which did not cluster around other HBV genotype E.

Conclusion: This study reports novel strains of HBV genotype E circulating in Nigeria.

Introduction/objectives: The study aimed to determine whether in children with newly diagnosed juvenile idiopathic arthritis (JIA) hepatitis B surface antibody (anti-HBs) differs from healthy children and to see whether the revaccination is safe and effective under JIA treatment.

Methods: Patients who were followed up with a diagnosis of JIA between January 2020 and February 2024 were included. The control group consisted of healthy children matched for age and gender.

Background: Hepatitis C virus (HCV) and hepatitis B virus (HBV) infections pose significant global health concerns, contributing to chronic liver diseases. Blood transfusion is identified as a potential route for the transmission of these viruses, necessitating effective screening strategies for blood donors. The aim of this study was to assess the significance of nucleic acid testing (NAT) in detecting HBV and HCV infections among blood donors who initially tested negative in serological tests.

Background: Due to the unique geographical and climatic conditions in Nagqu (Tibet), the blood station laboratory was only fully established and accredited by 2020. This study validated the performance of the laboratory's blood screening system and analyzed recent trends in blood donation and screening effectiveness.

Methods: Various serum samples were used to assess the performance of hepatitis B, hepatitis C, HIV, and syphilis tests, both serological and nucleic acid tests.

Hepatitis D virus (HDV) significantly influences the progression of liver diseases. Through clinical observations and database analyses, it has been established that patients coinfected with HDV and hepatitis B virus (HBV) experience accelerated progression toward cirrhosis, hepatocellular carcinoma (HCC), and liver failure compared to those infected solely with HBV. A higher viral load correlates with increased replicative activity, enhanced infectivity, and more severe disease manifestations.

Background/purpose: Dysbiosis of oral microbiota has been reported in late stage of chronic hepatitis B (CHB) infection with cirrhosis. CHB is characterized by the constant virus-induced liver injury which may lead to liver cirrhosis and hepatocellular carcinoma (HCC). However, some patients show normal liver function without antiviral treatment, associating with favourable prognosis.
