Polymorphism of the inosine triphosphate pyrophosphatase gene predicts ribavirin-induced anemia in chronic hepatitis C patients.
Ribavirin (RBV)-induced anemia is a serious side effect of pegylated interferon (PEG-IFN) plus RBV therapy which is the standard care most effective for hepatitis C virus (HCV) infection. In the present study, we investigated the association of inosine triphosphate pyrophosphatase (ITPA) genotypes with RBV-induced hemoglobin (Hb) reduction in HCV patients treated with PEG-IFN/RBV therapy. The g...
متن کاملP-121: Cloning and Expression of The Inosine Triphosphate Pyrophosphatase Gene Variant II in E.coli
Background Environmental and cellular inappropriate conditions can cause damages to cells nucleotide poll. Deamination and oxidation damages interfere with cell�s vital reactions. Inosine triphosphate pyrophosphatase (ITPA), an evolutionary conserved enzyme, plays a critical role in elimination of non-canonical bases. In human genome, the ITPA gene is located on chromosome 20 short arm and tran...
متن کاملcomparison of inosine triphosphate pyrophosphatase gene expression in chronic myelogenous leukemia patients and controls
objective: one of the most significant damages to the genetic material is oxidative deamination of dna and free nucleotides in the cell pool. incorporation of deaminated purine nucleotides such as inosine triphosphate (itp, ditp) into the dna can increase the frequency of base substitution mutation. it has been suggested that presence and accumulation of these rough nucleotides can lead to gene...
متن کاملModeling Ribavirin-Induced Anemia in Patients with Chronic Hepatitis C Virus.
Ribavirin remains an important component of hepatitis C treatment in certain clinical scenarios, but it causes hemolytic anemia. A quantitative understanding of the ribavirin exposure-anemia relationship is important in dose individualization/optimization. We developed a model relating ribavirin triphosphate (RTP) exposure in red blood cells (RBCs), RBC lifespan, feedback regulation of RBC prod...
متن کاملAn Index to Predict Ribavirin-Induced Anemia in Asian Patients With Chronic Genotype 1 Hepatitis C
BACKGROUND Single-nucleotide polymorphisms (SNP) in the inosine triphosphate pyrophosphatase (ITPA) gene correlate with ribavirin (RBV)-induced anemia in patients with chronic hepatitis C (CHC) receiving combination therapy. Managing anemia is an early priority in the treatment process. OBJECTIVES The aim was to develop a predictive index based on ITPA SNP status to identify CHC patients at r...
