Hepatitis C virus (HCV) treatment is aiming to cure and prevent the development, progression of fibrosis, and related complications. Interferon-based therapy was claimed to reduce or even reverse fibrosis. Although direct-acting agents have a better cure rate, we still lack the knowledge of their effect on fibrosis regression. We aim to assess fibrosis regression in direct-acting agents compared with interferon-based treatment regimens in the treatment of chronic HCV patients. The 204 chronic HCV patients were divided into 3 groups; group 1(N=68) received Peg-IFN and ribavirin, group 2 (N=69) received sofosbuvir and ribavirin, and group 3 (N=67) received Peg-IFN, ribavirin, and sofosbuvir. Fibrosis assessment was performed by transient elastography (TE), APRI and FIB 4, in the pretreatment and at least 3 months after end of treatment. Of these, 66.2% of the patients did not show significant fibrosis changes, 6.4% fibrosis progressed, and 27.5% of fibrosis regressed (P<0.0001) by TE. Similar results were detected in the different treatment regimens with no statistically significant difference between the regimens. Fibrosis regression was detected in 43.3% of cirrhotic patients who achieved sustained virological response (SVR) and only in 27.4% with significant fibrosis. Significant improvement of posttreatment aspartate transaminase, alanine transaminase, and alpha fetoprotein as well as APRI and FIB 4 scores were detected. Fibrosis regression (TE, APRI and FIB 4) was detected with direct-acting agents and interferon-based therapy. Treated patients with significant fibrosis will benefit of fibrosis regression irrespective to their treatment response, whereas fibrosis regression was associated with SVR in cirrhotic patients.
