Abstract

The incidence and prevalence of hepatitis C virus (HCV) infection among people who use drugs (PWUD) peaked in the 1980s in Amsterdam. As liver cirrhosis develops several decades after HCV infection and PWUD have other risk factors for liver fibrosis, we hypothesized that significant liver fibrosis or cirrhosis is now common among PWUD in Amsterdam. PWUD were recruited from the Amsterdam Cohort Studies, methadone programmes and addiction clinics during 2009-2016. Transient elastography was performed to assess liver stiffness. We estimated METAVIR fibrosis levels on the basis of the following liver stiffness measurements (LSMs) cut-offs: F0-F2 (no/mild) less than 7.65 kPa; F2-F3 (moderate/severe) at least 7.65 to less than 13 kPa; and F4 (cirrhosis) at least 13 kPa. Using linear regression models, we assessed the association between LSM and sociodemographic, clinical and behavioural determinants in (a) all PWUD and (b) chronic hepatitis C virus (cHCV)-infected PWUD. For 140 PWUD, the median LSM was 7.6 kPa (interquartile range=4.9-12.0); 26.4% had moderate/severe fibrosis and 22.9% had cirrhosis. Of 104 chronically infected PWUD, 57.7% had evidence of significant fibrosis (≥F2). In multivariable analysis including all PWUD, incre...Continue Reading
