Abstract

Objective: Hepatitis C virus (HCV) is an etiological agent responsible for occurrence of post-transfusion hepatitis in thalassemic patients. This study identified hepatitis C genotypes in pediatric and adolescent thalassemic patients and their correlation with age, blood transfusion, HCV RNA viral titer and liver function.
Methods: This study considers cross-sectional data from the Center for Thalassemia in Zahedan (Iran) carried out between August 2005 and September 2007. Twenty multitransfused patients suffering from β-thalassemia major and chronic HCV infection (13 males, 7 females) were included in the study. Patients were considered eligible for the study if they were seropositive for HCV RNA polymerase chain reaction (PCR) before initiation of evaluation. Blood sample was taken for HCV genotype and viral titer as well as biochemical markers. Type specific primer and real-time RT-PCR HCV were used for determination of viral genotype and HCV-RNA titer.
Findings: There was a significant positive correlation between serum HCV RNA titer and genotypes (P<0001). Serum HCV RNA levels were found higher in genotype 3a than in others. The most prevalent genotype in thalassemic patients was genotype 3a (40%) followed by 1b (25%), unclassified (20%) and la (15%). There was no meaningful relationship between genotype, Alanine aminotranferease, ferritin and alkaline phosphatase. Age, serum HCV RNA titer and number of transfusions were the only significant factors associated with genotypes (P<015, P<0.0001 and P<0.001 respectively).
Conclusion: This study showed that HCV genotype and viral titer are related to the number of blood transfusions received by thalassemic patients. Screening donated blood in blood banks would prevent the occurrence of hepatitis C in this high-risk group.
