Background Regression of fibrosis and improvement of portal hemodynamics after achievement of sustained viral response (SVR) in patients with chronic hepatitis C (HCV) is a subject of debate in different studies. Some studies reported improvement in the degree of fibrosis, while others did not find significant changes. Objective We aimed to evaluate changes in liver fibrosis, portal hemodynamics and clinical outcomes in patients with chronic HCV-related liver cirrhosis after the achievement of SVR with direct-acting antiviral drugs (DAAs). Patients and methods In our prospective longitudinal study, a total of 100 patients with chronic HCV infection-related liver cirrhosis were recruited, received DAAs, and completed the follow-up period. Clinical evaluation for assessment of liver disease severity using MELD and Child–Pugh class and scores were done. A noninvasive assessment of liver fibrosis using serum biomarkers (APRI index & FIB4 score) and share wave elastography (SWE) was done. Portal hemodynamic evaluation using Doppler ultrasound was done. All were done at baseline and 3 and 12 months after the end of therapy. Results A significant reduction in the degree of fibrosis was observed. Share wave elastography (SWE) readings showed 19.79% and 30.45% reduction 3 and 12 months after the end of therapy respectively ( P  < 0.001). Regarding the FIB4 score, the percentage of score reduction was 19.8% and 26.46% 3 and 12 months after the end of therapy, respectively ( P  < 0.01). APRI scores showed 22.6% and 41.09% reduction 3 and 12 months after the end of therapy respectively ( P  < 0.001). Significant improvement in Child–Pugh scores 3 and 12 months after the end of treatment was observed. Doppler ultrasound showed a significant increase in portal vein flow velocity, a significant decrease in time average mean velocity, and cross-section area 12 months after the end of treatment. Conclusion There was a considerable degree of reduction of liver fibrosis, improvement of portal hemodynamics, and Child–Pugh score in cirrhotic HCV patients who achieved SVR after DAAs.
