Abstract
Zanzibar, a low-resource semiautonomous region of Tanzania, has an estimated prevalence of hepatitis B virus (HBV) infections of 3.6%. To assess the feasibility of care and treatment, a 5-year hepatitis B demonstration project was implemented in Zanzibar during January 2017–December 2021, following the 2015 WHO HBV care and treatment guidelines. Participants included adults (aged ≥ 18 years) who tested positive for HBV surface antigen and tested negative for HIV and hepatitis C antibody. Participants were examined for clinical signs of liver disease and testing was conducted at baseline to assess treatment eligibility and every 6–12 months thereafter. Tenofovir disoproxil fumarate (TDF) was provided at no cost to treatment-eligible participants. Clinical and laboratory data were analysed to assess improvement in proximal disease outcomes. Among 596 participants enrolled, the median age was 32 years (IQR 26–39) and 365 (61%) were male. Of those enrolled, 268 (45%) returned for ≥ 1 follow-up visit, with a median of 511 days of follow-up. Overall, 58 patients initiated treatment: 15 met treatment criteria based on liver cirrhosis alone; 13 by APRI > 1.5; among those with HBV DNA results, six met criteria based on HBV DNA levels and ALT activity; 24 met ≥ 2 criteria. Significant decreases in ALT activities, APRI scores and HBV DNA levels were observed among those treated. This hepatitis B care and treatment programme was demonstrated to be feasible in a low-resource setting. Despite challenges, testing and linkage to care is critical to decrease the global burden of hepatitis B.
