| 4 | Monitoring hepatitis C virus treatment rates in an Opioid Treatment Program:A longitudinal study显示文摘BACKGROUND Direct-acting antivirals(DAAs)are recommended for the treatment of hepatitis C virus(HCV)infection in patients treated with methadone or buprenorphine.AIM To assess HCV treatment rates in an Opioid Treatment Program(OTP).METHODS This longitudinal study included 501 patients(81.4%men,median age:45 years;interquartile range:39-50 years)enrolled in an OTP between October 2015 and September 2017.Patients were followed until September 2019.Data on sociodemographics,substance use,HCV infection,human immunodeficiency virus(HIV)infection and laboratory parameters were collected at entry.We analyzed medical records to evaluate HCV treatment.Kaplan-Meier methods and Cox regression models were used to analyze the DAA treatment uptake and to identify treatment predictors.RESULTS Prevalence of HCV and HIV infection was 70%and 34%,respectively.Among anti-HCV-positive(n=336)patients,47.2%,41.3%,and 31.9%used alcohol,cannabis,and cocaine,respectively.HCV-RNA tests were positive in 233(69.3%)patients.Twentyeight patients(8.3%)cleared the infection,and 59/308(19.1%)had received interferon-based treatment regimens before 2015.Among 249 patients eligible,111(44.6%)received DAAs.Treatment rates significantly increased over time from 7.8/100 person-years(p-y)(95%CI:5.0-12.3)in 2015 to 18.9/100 p-y(95%CI:11.7-30.3)in 2019.In a multivariate analysis,patients with HIV co-infection were twice as likely to receive DAAs(HR=1.94,95%CI:1.21-3.12)than patients with HCV mono-infection.Current drug use was an independent risk factor for not receiving treatment against infection(HR=0.48,95%CI:0.29-0.80).CONCLUSION HCV treatment is evolving in patients with HCV-HIV co-infection.Ongoing drug use while in an OTP might negatively impact the readiness to treat infection. | Arantza Sanvisens Inmaculada Rivas Eva Faure Néstor Espinach Anna Hernandez-Rubio Xavier Majó Joan Colom Robert Muga | 2020 | World Journal of Gastroenterology2020，26，38： | 0 |
