Aim: A genetic polymorphism of inosine triphosphate pyrophosphatase (ITPA) has been associated with pegylated-interferon/ribavirin (PEG-IFN/RBV)-induced anemia in chronic hepatitis C patients. However, correlation of the genetic variant with anemia following liver transplantation has not been determined. Methods: Sixty-three hepatitis C virus (HCV)-positive patients who underwent liver transplantation and PEG-IFN/RBV therapy were enrolled. The rs1127354 was determined for each individual. Results: There was no relationship with anemia or RBV dosage in patients carrying the CC allele (CC group, n=43) and those carrying the CA allele (CA group, n=20). The incidence of hemoglobin (Hb) decline >3g/dL (CC: 4.7%, CA: 0%) was relatively low, whereas the incidence of Hb levels <10g/dL (CC: 18.6%, CA: 30.0%) was high. Univariate analysis revealed that splenectomy inversely correlated with Hb levels <10g/dL at 4weeks (P=0.04). Among the 22 patients who did not undergo splenectomy, the incidence of Hb levels <10g/dL tended to be lower in the seven patients carrying the CA allele (28.6%) than in the 15 patients with the CC allele (60.0%). Conclusion: The ITPA genetic polymorphism does not correlate with post-transplant PEG-IFN/RBV-induced anemia. Splenectomy is useful in preventing anemia regardless of the ITPA genotype.
