Observational Cohort Study of Clinical Outcomes After Antiviral Therapy for Chronic Hepatitis C

August 25, 2019 updated by: Yao Xie, Beijing Ditan Hospital

Observational Cohort Study of Clinical Outcomes After Antiviral Therapy in Chronic Hepatitis C Patients

This study was a clinical observational cohort study of two-way, non-intervention long-term dynamic follow-up. Enrolled in the Department of Liver Diseases, Beijing Ditan Hospital, Capital Medical University, with interferon combined with ribavirin (PR) antiviral therapy (PR treatment greater than or equal to 6 months) and/or direct acting antivirals (DAAs) In patients with chronic hepatitis C, the baseline, antiviral treatment and withdrawal follow-up data before the antiviral treatment were collected, and the patients were followed up for 3-6 months. Clinical data such as clinical biochemistry, HCV RNA and serological markers (anti-HCV), AFP and liver imaging (liver ultrasound) were collected during the study period. At least 144 weeks of observation on the virological response and clinical outcome of anti-viral treatment of chronic hepatitis C, the main evaluation index of liver cancer and decompensated liver cirrhosis after stopping the drug, and exploring the antiviral treatment of patients Long-term virological response and clinical outcomes, clarifying their influencing factors.

Interferon combined with ribavirin group
Interferon combined with ribavirin (PR) antiviral therapy (PR treatment for 6 months or more) in patients with chronic hepatitis C, collect basic data before antiviral therapy, and during the PR antiretroviral treatment period, Follow-up was performed every 3-6 months in March, June, September, December, DAAs antiviral treatment during January, March, and withdrawal follow-up, and clinical biochemistry, HCV RNA, and serological markers were used during follow-up ( anti-HCV), AFP and liver imaging (liver ultrasound) examination.
Drug: Interferon

Drug: ribavirin
Interferon combined with ribavirin antiviral therapy
DAAs treatment group
Patients with chronic hepatitis C treated with direct acting antivirals (DAAs), collect basic data before antiviral therapy, and during the period of PR antiviral treatment, January, March, June, September, December Follow-up was performed every 3-6 months during January, March, and withdrawal follow-up during DAAs antiviral therapy. Clinical biochemistry, HCV RNA and serological markers (anti-HCV), AFP, and liver imaging were performed at follow-up. Liver ultrasound) check.
