title: [Analysis of risk factors in anti-HCV positive patients in Gaziosmanpasa University Hospital, Tokat, Turkey].
abstract: Transmission routes and seroprevalence of hepatitis C virus (HCV) may vary between countries and geographic regions. In this study, we aimed to investigate the risk factors associated with the transmission of HCV in our region, Tokat (located at middle Black Sea region of Turkey). Ninety-seven patients (age range: 16- 78-years-old, mean age: 53.6 +/- 10 yrs; 15 male, 82 female) who were admitted to Infectious Diseases Clinics between September 2004 and February 2007 and found to be anti-HCV positive by microparticle enzyme immunoassay (Abbott, Axsym) were enrolled in this study. The patients were evaluated for the risk factors including blood transfusion, past surgery, medical abortion, dental therapy, history of endoscopy/bronchoscopy, intravenous (i.v.) drug use, hospitalization exceeding one week and hemodialysis. "Sexual contact with multiple partners" has not been evaluated as a risk factor since the sociocultural features of this specific region would possibly prevent obtaining true data. Overall, history of previous dental therapy (68%), medical abortion (63.4%), prolonged hospitalization (60%), and surgery (59.8%) were found to be the most prevalent risk factors, followed by blood transfussion (25.8%) and endoscopy (14.1%). The evaluation of the risk factors according to gender revealed that prolonged hospitalization (65.7%) was the most frequently detected risk factor in females and dental operations (86.7%) in males. Previous hospitalization was a more common risk factor in female cases compared to males (p< 0.05), however, there were no statistically significant differences for the other risk factors in terms of gender. No risk factor was identified in one patient (1%). Of the patients, 15.3% had one, 27.1% had two, 35.3% had three, 18.8% had four, and 2.4% had five different risk factors. None of the patients had a history of i.v. drug use. The results of this study demonstrated that dental therapy, prolonged hospitalization, surgery and medical abortus were the most frequently associated risk factors for HCV transmission. Thus, preventive measures that target these specific risk factors should be taken into consideration to prevent HCV transmission.
