BACKGROUND: Transfusion-transmitted hepatitis is the most important cause of transmitted infections by the parenteral route in patients with haemophilia.
OBJECTIVES: This study was performed to determine the prevalence of HBV, HCV, and different genotypes of HCV among haemophilia patients in Ahvaz city, southwest Iran.
PATIENTS AND METHODS: A cross-sectional study was conducted on 87 haemophilia patients referred to the Hemoglobinopathy and Thalassemia research centre during February 2008 to March 2009. Patients, sera were tested for HBsAg and anti-HCV using ELISA and confirmed by PCR (HBV) and RT-PCR (HCV). HCV genotypes were determined with HCV genotype specific primers using HCV genotyping kit.
RESULTS: The overall prevalence rate of HBsAg and anti-HCV were 1.1% (95% CI: 0-3.39) and 54% (95% CI: 43.5-64.4), respectively. Forty two of the anti-HCV patients (89.3%) were also HCV RNA positive. The prevalence of anti-HCV seropositivity was significantly higher (P = 0.0008) among patients who had started to receive transfusions before implementation of blood donor screening. Moreover, the number of transfusion were significantly associated with anti-HCV and HCV RNA positivity (P = 0.0041 and P = 0.023, respectively). The predominant HCV genotype among haemophilia patients in our region was 1a (26/42, 61.9%), although genotypes 1b and 3a were found in 26.1% (11/42) and 11.9% (5/42) of the patients, respectively.
CONCLUSIONS: It appears stringent donor selection procedures reduced HCV infection in multi-transfused patients, but it is still serious risk for these subjects.
