Real-Life Diagnostic Accuracy and Clinical Utility of Hepatitis B Virus (HBV) Nucleic Acid Testing Using the GeneXpert Point-of-Care Test System from Fresh Plasma and Dry Blood Spot Samples in The Gambia.

The GeneXpert HBV Viral Load test is a simplified tool to scale up screening and HBV monitoring in resource-limited settings, where HBV is endemic and where molecular techniques to quantify HBV DNA are expensive and scarce. However, the accuracy of field diagnostics compared to gold standard assays in HBV-endemic African countries has not been well understood. We aim to validate the diagnostic performance of the GeneXpert HBV Viral Load test in freshly collected and stored plasma and dried blood spot (DBS) samples to assess turn-around-time (TAT) for sample processing and treatment initiation, to map GeneXpert machines and to determine limitations to its use in The Gambia.

Clinical outcomes of untreated adults living with chronic hepatitis B in The Gambia: an analysis of data from the prospective PROLIFICA cohort study.

Background: Expanding antiviral therapy to people with chronic hepatitis B virus (HBV) infection who are ineligible to receive treatment under current international criteria has been increasingly debated. Evidence to support this approach is scarce, especially in Africa. We aimed to address this knowledge gap by analysing the clinical outcomes of people with chronic hepatitis B in The Gambia who were untreated and ineligible for antiviral therapy at diagnosis.

Beliefs surrounding the use of inhaled asthma medication in The Gambia: a qualitative study of asthma patients and healthcare workers.

Asthma-related mortality is high in low- and middle-income countries. Little is known about public perceptions of inhaled medicines. We conducted semi-structured interviews with asthma patients and healthcare workers at three secondary care facilities in The Gambia, between August and November 2022.

Validation of a real-time polymerase chain reaction for the detection and quantification of the nucleic acid of from equine clinical samples.

Unlabelled: var (HCF) is a dimorphic fungus that causes epizootic lymphangitis in equids. Current diagnostic approaches, including culture, microscopy, and clinical presentation, lack speed, sensitivity, and specificity when diagnosing clinical cases. In this study, equine blood and pus samples on Whatman FTA cards from Senegal ( = 3), The Gambia ( = 19), Ethiopia ( = 16), and Mali ( = 13) were tested using a real-time PCR (qPCR) protocol.
