Decentralised same day test and treatment of hepatitis C levering existing peer support networks among men who inject drugs: feasibility and effectiveness.

BACKGROUND: Prevalence of hepatitis C virus (HCV) infection among people who inject drugs in the state of Manipur, India, is 43%; however, access to care is poor. We piloted a Community-led and comprehensive hepatitis care model that included same-day HCV treatment at drug treatment centres. METHODS: Screening was conducted through venipuncture samples collected by community peer PWID, using HCV antibody (HCV Ab) rapid screening and hepatitis B virus (HBV) surface antigen (HBsAg) rapid diagnostic tests. Reactive HCV Ab samples were tested for HCV RNA using near point-of-care Truenat® HCV on Truelab® Quattro. Eligible HCV RNA-positive participants were treated on the same day using direct-acting antivirals and followed for sustained virologic response (SVR). HBsAg-negative participants received rapid HBV vaccination regimen while those positive for HBsAg were tested for DNA and referred for treatment. RESULTS: Between November 2021 and August 2022, 643 individuals were approached and 503 consented and were screened. All screened were males with history of injection drug use, and a median age of 27 years (IQR 23-32). Of the 241 (47.9%) HCV Ab reactive all underwent RNA testing and 156 (64.7%) were RNA detectable. Of those with viraemia, 155 (99.4%) were initiated on treatment with 153 (98.1%) on same day, with 2 (1.2%) HBsAg positive and waiting for HBV DNA results. Among those 153, median time from HCV Ab screening to treatment was 6 h 38 min (IQR 5 h 42 min-8 h 23 min). In total 155 (100%) completed HCV treatment, of those 148 (95.5%) completed SVR testing and 130 (87.8%) achieved SVR12. 27 (5%) participants were HBsAg-positive, 3 (11.1%) were also living with HCV viraemia; 443 (97.6%) were eligible for vaccination and 436 (98.4%) received all 3 vaccine doses. CONCLUSION: Community-led hepatitis care incorporating same day "test and treat" for HCV was feasible and effective. HBV screening identified a large proportion who were unvaccinated. Peer support extended resulted in ensuring compliance to care and treatment cascade and completing all the three doses of HBV vaccination. As the screening, diagnostics infrastructure and vaccine are available in most countries with national viral hepatitis programs also in place, our model can be adapted or replicated to progress towards global elimination targets.

The HepTestContest: a global innovation contest to identify approaches to hepatitis B and C testing.

BACKGROUND: Innovation contests are a novel approach to elicit good ideas and innovative practices in various areas of public health. There remains limited published literature on approaches to deliver hepatitis testing. The purpose of this innovation contest was to identify examples of different hepatitis B and C approaches to support countries in their scale-up of hepatitis testing and to supplement development of formal recommendations on service delivery in the 2017 World Health Organization hepatitis B and C testing guidelines. METHODS: This contest involved four steps: 1) establishment of a multisectoral steering committee to coordinate a call for contest entries; 2) dissemination of the call for entries through diverse media (Facebook, Twitter, YouTube, email listservs, academic journals); 3) independent ranking of submissions by a panel of judges according to pre-specified criteria (clarity of testing model, innovation, effectiveness, next steps) using a 1-10 scale; 4) recognition of highly ranked entries through presentation at international conferences, commendation certificate, and inclusion as a case study in the WHO 2017 testing guidelines. RESULTS: The innovation contest received 64 entries from 27 countries and took a total of 4 months to complete. Sixteen entries were directly included in the WHO testing guidelines. The entries covered testing in different populations, including primary care patients (n = 5), people who inject drugs (PWID) (n = 4), pregnant women (n = 4), general populations (n = 4), high-risk groups (n = 3), relatives of people living with hepatitis B and C (n = 2), migrants (n = 2), incarcerated individuals (n = 2), workers (n = 2), and emergency department patients (n = 2). A variety of different testing delivery approaches were employed, including integrated HIV-hepatitis testing (n = 12); integrated testing with harm reduction and addiction services (n = 9); use of electronic medical records to support targeted testing (n = 8); decentralization (n = 8); and task shifting (n = 7). CONCLUSION: The global innovation contest identified a range of local hepatitis testing approaches that can be used to inform the development of testing strategies in different settings and populations. Further implementation and evaluation of different testing approaches is needed.
