ABSTRACT
Plain language summary Achievement of elimination of HCV as a major public health threat requires focus on vulnerable populations such as people in prison. The prison population is at high risk of HCV infection but their treatment is complicated by social issues such as mental health disorders and drug use. Simple and effective treatment regimens are required to increase access to treatment and improve cure rates. This real-world analysis across Europe and Canada analyzed data from 20 prison populations. HCV-infected individuals were treated with sofosbuvir/velpatasvir, a once daily treatment which requires minimal monitoring. This regimen achieved high cure rates in the prison population despite the existence of complicating social issues. Background: People in prison are at high risk of hepatitis C virus (HCV) infection and often have a history of injection drug use and mental health disorders. Simple test-and-treat regimens which require minimal monitoring are critical. Methods: This integrated real-world analysis evaluated the effectiveness of once daily sofosbuvir/velpatasvir (SOF/VEL) in 20 prison cohorts across Europe and Canada. The primary outcome was sustained virological response (SVR) in the effectiveness population (EP), defined as patients with a valid SVR status. Secondary outcomes were reasons for not achieving SVR, adherence and time between HCV RNA diagnosis and SOF/VEL treatment. Results: Overall, 526 people in prison were included with 98.9% SVR achieved in the EP (n = 442). Cure rates were not compromised by drug use or existence of mental health disorders. Conclusion: SOF/VEL for 12 weeks is highly successful in prison settings and enables the implementation of a simple treatment algorithm in line with guideline recommendations and test-and-treat strategies.
ABSTRACT
OBJECTIVES: Public Health England (PHE) aims meet the WHO target to eliminate hepatitis C as a public health concern by 2030. One aspect of this strategy is to use historical surveillance data of anti-HCV positive patients identified by PHE to re-engage with offers of PCR testing and treatment if RNA-positive. Operational Delivery Networks (ODN), who deliver Hepatitis C treatment across 22 regions in England, are responsible for enacting this initiative. This study aims to evaluate the effectiveness of using this data with regional PCR results to re-engage HCV-infected persons in the West Midlands region of England. STUDY DESIGN: A longitudinal prospective study using historical surveillance data. METHODS: A dataset of historical anti-HCV positive antibody patients provided to the ODN by PHE was cross-referenced with HCV RNA data from 01/01/1996 to 01/01/2019 from five laboratories across the West Midlands. Letters were sent to the general practitioner and to the patients who were HCV RNA positive to invite them for repeat testing and treatment to achieve cure. RESULTS: From a dataset of 4540 anti-HCV antibody results, 31.7% (n=1440) had a PCR result: 48.1% (n=693) were PCR positive for HCV RNA. 693 letters were sent to GPs with responses from 14.2% (n=99). By May 2021, only 212 patient letters were sent (due to significant interruption by the COVID-19 pandemic) and 11.3% (n=24) replied, 17 presented for PCR testing and 4 were found to be viraemic. To date, one patient has achieved cure and three have completed treatment awaiting confirmation of cure. CONCLUSION: The use of historical anti-HCV antibody results can be used to successfully re-engage people into testing and treatment for hepatitis C, albeit with modest gains.
