Feasibility of implementing viral hepatitis services into a correctional service facility in Cape Town, South Africa.

Background: Hepatitis B virus (HBV) and hepatitis C virus (HCV) are estimated to be of the most prevalent infectious diseases in correctional settings worldwide. However, viral hepatitis services have not been routinely integrated into South African correctional facilities. We aimed to assess prevalence of HBV infection and HCV infection among people accessing HIV services and assess the feasibility of viral hepatitis service integration in a South African correctional centre.

Methods: Voluntarily participating people in a correctional services facility were offered free hepatitis B surface antigen (HBsAg) and anti-HCV point-of-care testing in addition to routine HIV testing and treatment services on a first-come, first-served basis during June 2021-March 2022. Off-site laboratory testing (HBV and HCV molecular testing and non-invasive liver fibrosis staging) and screening for hepatocellular carcinoma informed further management. A general practitioner at the facility managed participants, with virtual support from hepatologists. Data on age and history of injecting was collected and point-of-care and laboratory results were recorded. Data were analysed using descriptive statistics.

Results: The median age of the 765 people who participated was 32.5 years (IQR 27.5 - 38.2), with 2.2% (17/765) reporting having ever injected a drug. The sample prevalence was 3.9% (30/765) for HBV infection, 0.5% (3/665) for HCV infection, and 1.2% (9/765) for HIV-HBV coinfection. Thirty people had reactive HBsAg point-of-care tests. Among those with reactive HBsAg point-of-care tests 90.0% (27/30) received work-up, among whom 48.1% (13/27) were monitored, 44.4% (12/27) were placed on treatment and two people were released before a management plan could be finalised. Of those treated 33.3% (4/12) started tenofovir/emtricitabine and 66.7% (8/12) antiretroviral therapy. Of the eligible participants, 27.3% (201/735) received at least one hepatitis B vaccine dose and 26.9% (54/201) received three doses. All three participants who had confirmed HCV infection were started on direct-acting antivirals. Of the two completing treatment one achieved sustained virological response at 12 weeks (SVR12), one person was released before SVR12 was done. One person was lost to follow-up. No clinical adverse events were reported.

Conclusion: There was a notable viral hepatitis burden among people in this correctional centre and integration of viral hepatitis services into the existing HIV services was acceptable and feasible. Further efforts to sustain and expand access to viral hepatitis services in South African correctional centres could catalyse national viral hepatitis elimination efforts.
