Ribavirin (RBV)-induced anemia is one of the major causes of dose reduction and discontinuation of therapy for chronic hepatitis C (CHC) patients. We investigated the role of inosine triphosphate pyrophosphatase (ITPA) single nucleotide polymorphism (SNP) (rs1127354) in predicting RBV-induced anemia and thrombocytopenia among Egyptian patients with CHC genotype 4 infection. One hundred and twenty Egyptian patients with CHC genotype 4 who had received standard of care combination therapy were enrolled in this study. Single nucleotide polymorphism at ITPA (rs1127354) was genotyped by real-time detection polymerase chain reaction. Hb levels between CC and non-CC groups were significantly different at weeks 4, 8, and 12. Hemoglobin decline was significantly higher among CC patient than non-CC patients at week 4 and week 8 of treatment. The RBV dose reduction was higher in CC than non-CC group. Platelet decline was significantly lower in CC patients than non-CC patients at baseline, 4, 12 weeks only. Rs1127354 ITPA polymorphism was associated with RBV-induced anemia and thrombocytopenia in Egyptian patients with hepatitis C virus genotype 4 infection.
