Abstract
Background: People who inject drugs (PWID) are at high risk of blood-borne infections, and injection drug use contributes significantly to hepatitis C virus (HCV) transmission. The WHO has therefore set targets of reducing HCV incidence and prevalence among PWID and increasing treatment coverage to eliminate HCV by 2030. The DRUCK study (2011-2014) found high HCV prevalence and low treatment coverage among PWID in Germany. To assess progress in the elimination of HCV among PWID, we conducted a cross-sectional study in two German federal states that piloted a future monitoring.
Methods: PWID aged 16 + who injected drugs (previous 12 months) were recruited in low-threshold drug services and opioid agonist treatment (OAT) practices in Berlin and Bavaria between June 2021 and April 2022. Participants completed a questionnaire on sociodemographics, behaviours and access to care, and were tested for hepatitis B virus (HBV) and HCV, and HIV. Data was analysed regarding HCV prevalence, history of treatment, and risk and prevention behaviours. Results were compared with the DRUCK study.
Results: A total of 588 PWID, with a median age of 39 (range: 17-66) years and 68% (399/587) male, were included in the analysis. Of the participants, 61% (353/574) reported receiving OAT and 14% (66/469) recent use of shared needles/syringes during the last 30 days. History of imprisonment was reported by 77% (444/577) and history of homelessness by 75% (428/569) of participants. Among anti-HCV positive participants, viraemic HCV infections decreased by 44% from 66% (904/1361) in 2011-2014 to 37% (160/432) in 2021-2022, while those with cleared HCV infection and treatment history increased from 20% (266/1361) to 34% (148/432).
Conclusions: Despite a decrease since 2011-2014, viraemic HCV prevalence among PWID in Germany remains high, and treatment coverage is still insufficient. To achieve the WHO targets, universal health coverage and targeted integrated testing and treatment for PWID are needed. PWID receiving OAT and people in prison should be offered testing and treatment at any contact with the medical system. A nationwide monitoring system will help assess successes and remaining gaps, and track progress towards elimination of HCV among PWID in Germany.
期刊介绍：
Harm Reduction Journal is an Open Access, peer-reviewed, online journal whose focus is on the prevalent patterns of psychoactive drug use, the public policies meant to control them, and the search for effective methods of reducing the adverse medical, public health, and social consequences associated with both drugs and drug policies. We define "harm reduction" as "policies and programs which aim to reduce the health, social, and economic costs of legal and illegal psychoactive drug use without necessarily reducing drug consumption". We are especially interested in studies of the evolving patterns of drug use around the world, their implications for the spread of HIV/AIDS and other blood-borne pathogens.
