Résumé
Rapid virologic response (RVR) is defined as undetectable hepatitis C virus (HCV) RNA in serum after 4 weeks of treatment for chronic hepatitis C (CHC). Paritaprevir/ritonavir/ombitasvir (PRO) and/or dasabuvir (D), with or without ribavirin [PRO (D) ± ribavirin], which are direct-acting antivirals (DAAs), is the currently approved treatment regimen for CHC genotype 1; this regimen can also be used in patients with end-stage renal failure (ESRF). In this study, we aimed to evaluate the effect of pretreatment factors on RVR in patients treated with PRO (D) ± ribavirin. This study included 60 patients with CHC genotype 1 who were treated with PRO (D) ± ribavirin and achieved RVR. Patients' demographic data; baseline HCV RNA levels; HCV genotype information; biochemical, histologic, and radiologic results; and previous treatment history were recorded. Patients were categorized into two groups: virologic responses achieved in the first week (group 1) and in the first to the fourth week (group 2). Pretreatment factors were compared between the groups. Patients in group 1 who achieved ultraRVR (undetectable HCV RNA after 1 week of treatment) had significantly lower mean pretreatment HCV RNA levels and lower prevalence of ESRF than patients in group 2. RVR has been indicated to be a robust positive predictor of sustained virologic response. We concluded that some pretreatment factors such as low HCV RNA level and absence of ESRF might lead to faster RVR and shorter treatment duration with DAAs for CHC.

BACKGROUND AND STUDY AIMS
OBJECTIVE
Rapid virologic response (RVR) is defined as undetectable hepatitis C virus (HCV) RNA in serum after 4 weeks of treatment for chronic hepatitis C (CHC). Paritaprevir/ritonavir/ombitasvir (PRO) and/or dasabuvir (D), with or without ribavirin [PRO (D) ± ribavirin], which are direct-acting antivirals (DAAs), is the currently approved treatment regimen for CHC genotype 1; this regimen can also be used in patients with end-stage renal failure (ESRF). In this study, we aimed to evaluate the effect of pretreatment factors on RVR in patients treated with PRO (D) ± ribavirin.
PATIENTS AND METHODS
METHODS
This study included 60 patients with CHC genotype 1 who were treated with PRO (D) ± ribavirin and achieved RVR. Patients' demographic data; baseline HCV RNA levels; HCV genotype information; biochemical, histologic, and radiologic results; and previous treatment history were recorded. Patients were categorized into two groups: virologic responses achieved in the first week (group 1) and in the first to the fourth week (group 2). Pretreatment factors were compared between the groups.
RESULTS
RESULTS
Patients in group 1 who achieved ultraRVR (undetectable HCV RNA after 1 week of treatment) had significantly lower mean pretreatment HCV RNA levels and lower prevalence of ESRF than patients in group 2.
CONCLUSIONS
CONCLUSIONS
RVR has been indicated to be a robust positive predictor of sustained virologic response. We concluded that some pretreatment factors such as low HCV RNA level and absence of ESRF might lead to faster RVR and shorter treatment duration with DAAs for CHC.
