BackgroundHepatitis C virus (HCV) can cause chronic liver disease, hepatic cirrhosis, hepatocellular carcinoma, liver transplantation, and death. Early diagnosis and treatment are thus vital.ObjectivesWe aimed to investigate the sustained virological response (SVR) rates in chronic hepatitis C patients infected with different genotypes, receiving different direct-acting antiviral treatments (DAAs).DesignRetrospective, observational SETTING: Clinic for infectious diseases and clinical microbiology PATIENTS AND METHODS: Patients diagnosed with chronic hepatitis C who applied to our outpatient clinic between January 2016 and November 2022 and were treated with a DAA were included in the study. Treatment responses were evaluated after each patient was treated with either ledipasvir plus sofosbuvir (LDV/SOF), LDV/SOF + ribavirin (RBV), SOF+RBV, ombitasvir/paritaprevir/ritonavir plus dasabuvir (OBV/PTV/r±DSV) ±RBV, or glecaprevir plus pibrentasvir (GLE/PIB).Main Outcome MeasuresSustained virological response (SVR) rates at 12 weeks (SVR12) post-treatment.Sample Size360 patients.ResultsOf 360 patients who met the inclusion criteria, 218 (60.6%) were male and 142 (39.4%) were female with no statistically significant differences in SVR between sexes (P=.252). Nearly all had a SVR (n=353, 98.1%). The median (IQR) age of the patients was 56 (30.3) years. There were 42 (11.7%), 199 (55.3%), 4 (1.1%), 106 (29.4%), 8 (2.2%) and 1 (0.3%) patient with genotypes 1a, 1b, 2, 3, 4 and 5, respectively, and SVR12 did not differ significantly between genotypes (P=.066). SVR12 response was higher in 246 (68.3%) non-injecting drug users compared to 114 (31.7%) injecting drug users (P=.005). The SVR12 response was achieved in 100% of patients with genotypes 1a, 2, 4, and 5. SVR12 response could not be obtained in 1 of 199 genotype 1b patients and 6 of 106 genotype 3 patients. The common feature of 6 reinfection patients with genotype 3 was that they were using intravenous drugs. These 6 patients were reinfected due to their continued intravenous drug use.ConclusionIn conclusion, DAAs provide high SVR12 rates in cirrhotic/non-cirrhotic, pegylated interferon-naive/experienced patient groups and in patients infected with all genotypes. DAAs have a high SVR12 rate in patients with chronic hepatitis C.LimitationsRetrospective, single-center.
