Study of the effect of direct acting antivirals (DAAs) on fibrosis in chronic hepatitis C patients using transient elastography

Back ground: As DAA agents are leading to enormous cure rates, so identifying and monitoring patients who remain at a high complication risk after achieving SVR continue to be a critical issue. Numerous validated methods for noninvasive measurement of liver fibrosis can be used in the management of HCV infection.
Methods study: A total of 50 Egyptian chronic HCV patients eligible for treatment with DAAs were enrolled in this prospective study. All subjects selected from Virology Unit of Tropical Medicine Department, Faculty of Medicine, Beni-Suef University received DAAs (SOV DCV) the endpoint was a sustained virologic response at 12 (SVR12) weeks post-treatment. All participants were evaluated non-invasively by Liver Stiffness Measurement (LSM) by Fibro Scan before DAAs treatment, and 6 months post-treatment.
Results: SVR achieved by DAAs therapy was 96 % and was associated with significant improvement (p ˂0.05) of non-invasive fibrosis markers (FIB-4, APRI score, and LSM by Fibro Scan) from baseline compared to 6 months post-treatment. Using fibro scan regression of fibrosis in 30/45 patients (66%). Liver inflammation and synthetic functions also improved on follow up 12w and 6m post treatment.
Conclusion: Regression of Liver inflammation and fibrosis in chronic hepatitis C patients post treatment with SOF DCV
