In this breastmilk pharmacokinetic study of women undergoing hepatitis C virus treatment with sofosbuvir/velpatasvir, sofosbuvir, GS-331007 (sofosbuvir metabolite), and velpatasvir concentrations in breast milk were 13%, 1.2%, and 41% of maternal plasma concentrations, respectively. The estimated infant daily dose from breastmilk was <1% of the weight-adjusted dose for children.

Accurate timing estimates of when participants acquire HIV in HIV prevention trials are necessary for determining antibody levels at acquisition. The Antibody-Mediated Prevention (AMP) Studies showed that a passively administered broadly neutralizing antibody can prevent the acquisition of HIV from a neutralization-sensitive virus. We developed a pipeline for estimating the date of detectable HIV acquisition (DDA) in AMP Study participants using diagnostic and viral sequence data.

Discontinuing antivirals in chronic hepatitis B virus (HBV) 'e' antigen negative infection can enhance HBV surface antigen (HBsAg) loss but risks complications. We modelled the clinical impact of discontinuing antivirals in chronic HBV. We developed a Markov state model with Monte Carlo simulation of chronic HBV to compare continuation of antiviral therapy with 3 strategies of cessation and reinitiation for: (1) virologic relapse, (2) clinical relapse, or (3) hepatitis flare.

Hepatitis B virus (HBV) infection is a global health challenge, with the World Health Organization (WHO) targeting its elimination by 2030. Jordan lacks sufficient data on HBV epidemiology, including prevalence, incidence and clearance. This study addresses these gaps through a retrospective analysis of HBV testing data from 40,268 individuals collected at Biolab Diagnostic Laboratories (2010-2024).

When CMV is untreated, it can cause pneumonitis, colitis, hepatitis, and encephalitis. Current diagnosis relies on molecular methods with qPCR as the preferred method.

Hepatitis B virus (HBV) infection is a serious public health concern worldwide, especially during pregnancy due to the associated health risks for the mother and fetus. This study aimed to explore the relationship between alanine aminotransferase (ALT) levels, age and HBV DNA levels in pregnant women with chronic HBV infection. Our cohort study included 1743 pregnant women with HBV who gave birth from January 2021 to June 2024.
