Objectives: To analyse the variation of hepatitis C virus (HCV) prevalence and genotype distribution and their determinants in people living with human immunodeficiency virus (HIV) who entered care between 1997 and 2015. Methods: HIV-infected patients enrolled in ICONA who were tested for HCV antibodies (HCV-Ab) were included. Results: Overall 3407 of 12 135 (28.1%) were HCV-Abþ; and 735 of 12 135 (6.1%) were HBsAgþ. Among patients whose HCV genotypewas known, the most represented were genotypes 1 and 3. The prevalence of HCVinfection decreased from49.2% (2565/5217) during 1997e2002 to 10.2% (556/5466) during 2009e2015. The frequency of genotype 1a increased from 29.0% (264/911) to 43.0% (129/300), whereas genotype 3 decreased from 38.5% (351/911) to 27.0% (81/300). Independent predictors of HCV-Abþ status were being female (adjusted OR (AOR) 1.23, 95% CI 1.04e1.50, p ¼ 0.01), risk category (versus injecting drug users:men who have sex with men AOR 0.01, 95% CI 0.01e0.01, p <0.001; heterosexuals AOR 0.01, 95% CI 0.01e0.01, p <0.001; other/unknown AOR 0.02, 95% CI 0.01e0.02, p <0.001), being cared for in Central Italy (versus being cared for in Northern Italy: AOR 0.85, 95% CI 0.73e0.98, p <0.001), being Italian-born (AOR 1.44, 95% CI 1.16e1.80, p ¼ 0.001) and being enrolled in less recent calendar years (versus 1997e2002: 2009e2015 AOR 0.23, 95% CI 0.19e0.27, p <0.001; 2003e2008 AOR 0.49, 95% CI 0.41e0.61, p <0.001). Conclusions: The prevalence of HCV infection in HIV-infected patients entering into care in Italy significantly declined in more recent calendar years. After adjusting for risk factors and calendar years, HCV co-infection was more frequent in females and in those born in Italy.
