Introduction: Chronic hepatitis C virus (HCV) infection is one of the important causes of liver cancer and cirrhosis all over the worldwide. Methods: The data of the patients diagnosed with chronic hepatitis C infection who applied to the Adult Infectious Diseases and Clinical Microbiology Outpatient Clinic of Erzincan Binali Yildirim University, Mengücek Gazi Training and Research Hospital were retrospectively analyzed. Accordingly, 51 patients treated with direct-acting oral antiviral drugs (DAAs) between January 2016 and May 2021 were included in the study. Patients whose treatment is still ongoing, whose treatment was completed but did not come to the 12th week after treatment, or whose control time has not yet come, were excluded from the study. Results: It was observed that 58.8% of the cases participating in the study were male, 80.4% were infected with genotype 1b, and 74.5% were treatment-naive. When the treatment regimens used in the cases were examined, glecaprevir/pibrentasvir in 7.8%, sofosbuvir (SOF)/ledipasvir (LED), SOF/LED/ribavirin, and SOF/ribavirin in 15.7%, ombitasvir (OBV)/paritaprevir (P)/ritonavir (R)/dasabuvir and OBV/P/R/ribavirin in 76.5% (n=39) appears to be used. A statistically significant difference was found between the alanine aminotransferase, aspartate aminotransferase measurements, and platelet counts of the subjects participating in the study at the beginning, at the 4th week, at the end of the treatment, and at the 12th week (p=0.001). In these cases, a sustained virological response was achieved in 100%. In the follow-up of the cases, no serious side effects that required drug discontinuation were observed. Conclusion: Our study showed that the treatment success of DAAs is 100% and their side-effect profiles are good.
