Evidence of infection with delta agent was sought in 284 patients with acute hepatitis B referred to Fairfield Hospital, Melbourne, between July 1, 1981, and June 30, 1982 and in 127 hepatitis B surface antigen (HBsAg) carriers. Acute and convalescent serum samples from the patients with acute hepatitis B and single or multiple sera from the HBsAg carriers were tested for delta antigen (delta ag) and/or antibody (anti-delta) by solid-phase radioimmunoassay (SPRIA). Evidence of infection was detected in 14.4% of patients with acute hepatitis B and 7.1% of chronic HBsAg carriers. Eighty-eight percent of those in whom delta agent infection was demonstrated were intravenous drug users.

Stress is linked to oxidative imbalance, neuroendocrine system malfunction, and cognitive dysfunction. It is a recognized cause of neuropsychiatric diseases. Natural flavonoid apigenin (API) has neuroprotective and antidepressant properties, but little is known about its potential in restoring memory function under stress-related circumstances.

Background: Hepatitis B (HBV) and Delta (HDV) virus infections pose critical public health challenges, particularly in Romania, where HDV co-infection is underdiagnosed.
Methods: This study investigates the epidemiology, risk factors, and clinical outcomes of HBV/HDV co-infection in vulnerable populations, leveraging data from the LIVE(RO2) program. Conducted between July 2021 and November 2023, the program screened 320,000 individuals across 24 counties, targeting socially disadvantaged groups such as rural residents, the Roma community, and those lacking health insurance.

Information on circulating HBV (sub-)genotype, variants, and hepatitis D virus (HDV) coinfection, which vary by geographical area, is crucial for the efficient control and management of HBV. We investigated the genomic characteristics of HBV (with a prevalence of 8.1%) and the prevalence of HDV in Nigeria.

Hepatitis B virus (HBV) infections remain a significant global health challenge, especially in low- and middle-income countries where access to healthcare services is often limited. This study aimed to assess the prevalence of hepatitis B virus (HBV), hepatitis delta virus (HDV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) co-infections in a cohort of 426,528 patients tested for HBsAg in Romania between 2018 and 2023. Of the 17,082 HBsAg-positive individuals (4.

Chronic hepatobiliary damage progressively leads to fibrosis, which may evolve into cirrhosis and/or hepatocellular carcinoma. The fight against the increasing incidence of liver-related morbidity and mortality is challenged by a lack of clinically validated early-stage biomarkers and the limited availability of effective anti-fibrotic therapies. Current research is focused on uncovering the pathogenetic mechanisms that drive liver fibrosis.
