Inosine triphosphatase (ITPA) single nucleotide polymorphisms (SNPs) are strongly associated with protection against ribavirin (RBV)-induced anaemia in European, American and Asian patients; however, there is a paucity of data for Brazilian patients. The aim of this study was to evaluate the ITPA SNP (rs7270101/rs1127354) frequency in healthy and hepatitis C virus (HCV)-infected patients from B...

TWO VARIANTS OF THE INOSINE TRIPHOSPHATASE (ITPA rs1127354, rs7270101) gene cause ITPA deficiency and protect against the hemolytic toxicity of ribavirin. We investigated the clinical significance of ITPA variants in Korean patients treated with pegylated interferon (PEG-IFN) plus ribavirin. Of the 133 patients, 108 were CC and 25 were non-CC at rs1127354 (groups A and B, respectively). On the ...

This prospective study investigated the relationship between 2 inosine triphosphatase (ITPA) polymorphisms (rs7270101 and rs1127354) and the efficacy of ribavirin-based antiviral therapy in hepatitis C virus (HCV)-infected Chinese patients.A total of 906 patients diagnosed with chronic hepatitis C receiving pegylated interferon (PEG-IFN) plus ribavirin combination therapy between January 2011 a...

ناباروری به عنوان عدم موفقیت در بارداری بعد از یک سال رابطه جنسی بدون استفاده از روش های جلوگیری از بارداری تعریف می شود. حدود 8 الی 10 درصد زوجین با نوعی مشکل ناباروری مواجه هستند و حدود نیمی از موارد آن با عوامل مردانه است. در حین اسپرماتوژنز در پستانداران از جمله انسان ، سلولهای پیش ساز جنسی مردان دچار تکثیر میتوزی ، تقسیم میتوز و تمایز می شوند تا اسپرم های بالغ و هاپلویید را جهت تولید مثل ج...

UNLABELLED Two functional variants in the inosine triphosphatase (ITPA) gene causing inosine triphosphatase (ITPase) deficiency protect against ribavirin (RBV)-induced hemolytic anemia and the need for RBV dose reduction in patients with genotype 1 hepatitis C virus (HCV). No data are available for genotype 2/3 HCV. We evaluated the association between the casual ITPA variants and on-treatment ...

OBJECTIVES Infertility is a common human disorder which is defined as the failure to conceive for a period of 12 months without contraception. Many studies have shown that the outcome of fertility could be affected by DNA damage. We attempted to examine the association of two SNPs (rs1127354 and rs7270101) in ITPA, a gene encoding a key factor in the repair system, with susceptibility to infert...

BACKGROUND Severe anemia is a common side effect of Pegylated Interferon + Ribavirin (PR) and Telaprevir (TVR) in hepatitis C virus (HCV) genotype 1 patients with advanced fibrosis or cirrhosis (F3-F4). Inosine triphosphatase (ITPA) genetic variants are associated with RBV- induced anemia and dose reduction. AIM To test the association of ITPA polymorphisms rs1127354 and rs7270101 with hemogl...

The purine analogues tenofovir and abacavir are precursors of potential substrates for the enzyme Inosine 5'-triphosphate pyrophosphohydrolase (ITPase). Here, we investigated the association of ITPase activity and ITPA genotype with the occurrence of adverse events (AEs) during combination antiretroviral therapy (cART) for human immunodeficiency virus (HIV) infection. In 393 adult HIV-seroposit...
