Characteristics and antiviral treatment eligibility of patients diagnosed with hepatitis B at a teaching hospital in Ghana: Implications for prevention and management.

Hepatitis B virus (HBV) infection poses a considerable public health challenge in limited-resource settings especially in the sub-Saharan African region. Even though HBV infection is incurable, timely treatment is effective in preventing disease progression to liver cirrhosis or hepatocellular carcinoma. However, not all infected patients require treatment. The aim of the study was to determine the clinical, immunological, and virological profiles of treatment naïve patients with HBV infection, seen at the outpatient clinic of the Cape Coast Teaching Hospital. Additionally, the study sought to determine the antiviral treatment eligibility rate based on the 2015 guidelines of the World Health Organization (WHO) compared with the new 2024 guidelines. A hospital-based cross-sectional study involving total sampling of 220 treatment naïve HBV surface antigen positive clients was carried out. A structured questionnaire was used to collect data that were analyzed with STATA version 16. The median age at diagnosis was 34 years (IQR 26.0-41.5) with a male to female ratio of 1:1.5. A total of 138 participants (62.7%) were diagnosed with HBV infection following voluntary testing. There was a median delay of 8.5 months (IQR 3.0-22.5) between initial diagnosis and patients' presentation for medical care. In all, 24 patients (10.9%) had abnormal clinical examination findings, 172 patients (78.2%) had HBV DNA levels ≤ 2000 IU/ml whereas 8 (3.6%) were seropositive for the HBV envelope antigen. A few patients had concomitant human immunodeficiency virus (2.7%) and hepatitis C virus (1.4%) infections. Treatment eligibility rate based on the WHO 2015 guidelines was 6.4% (n = 14), however, with the updated 2024 guidelines, treatment eligibility was 42.3% (n = 93). Increasing the screening rate among the general population, early linkage to clinical care of screen positives and vaccination of screen negatives will help reduce HBV-related clinical conditions in resource-limited settings.
