BACKGROUND Human genetic factors influence the outcome of pegylated interferon and ribavirin hepatitis C therapy. We explored the role of IL28B, APOH and ITPA SNPs on the outcomes of triple therapy including telaprevir or boceprevir in patients with compensated cirrhosis chronically infected with HCV-1. PATIENTS AND METHODS A total of 256 HCV-1 Caucasian treatment-experienced patients with co...
BACKGROUND & AIMS In the last decade, pegylated interferon-α (PegIFN-α) plus ribavirin (RBV) was the standard treatment of chronic hepatitis C for genotype 1, and it remains the standard for genotypes 2 and 3. Recent studies reported associations between RBV-induced anemia and genetic polymorphisms of concentrative nucleoside transporters such as CNT3 (encoded by SLC28A3) and inosine triphospha...
BACKGROUND/OBJECTIVE Genetic polymorphisms in the inosine triphosphatase (ITPA) gene have been associated with the protection from early ribavirin(RBV)-induced hemolytic anemia among patients with chronic hepatitis C virus (HCV) infection. The aim of the present study was to investigate the association between the functional ITPA variants and hematological side effects during antiviral therapy ...
42 Background 43 Polymorphisms of the ITPA gene have been associated with anemia during 44 combination therapy in HCV mono-infected patients. Our aim was to confirm this 45 association in HIV/HCV co-infected patients 46 Methods 47 In this prospective, observational study, 73 HIV/HCV co-infected patients treated with 48 Peg-IFN plus RBV were enrolled. Two SNPs within or adjacent to ITPA gene (rs...
Background: Infertility is a relatively common problem that affects couples worldwide. It is estimated that approximately 1 in 6 couples will experience difficulties in reproducing, defined as a failure to conceive after two years of unprotected sexual intercourse. The molecular and genetic factors underlying the cause of infertility remain largely undiscovered. ITPA is an inosine triphosphatas...
Polymorphisms of the ITPA gene have been associated with anemia during combination therapy in hepatitis C virus (HCV)-monoinfected patients. Our aim was to confirm this association in HIV/HCV-coinfected patients. In this prospective, observational study, 73 HIV/HCV-coinfected patients treated with pegylated interferon plus ribavirin (RBV) were enrolled. Two single nucleotide polymorphisms withi...
BACKGROUND Inosine triphosphatase (ITPase) is encoded by the polymorphic gene ITPA and maintains low intracellular levels of the inosine nucleotides ITP and dITP. The most frequently reported polymorphisms are ITPA c.94C>A (rs 1127354) and ITPA c. 124+21 A>C (rs7270101). Some nucleoside-analogues used in the treatment of HIV-seropositive (HIV+) patients are potential substrates for ITPase. Ther...
BACKGROUND It has been found that ITPase deficiency is caused by ITPA gene polymorphisms. It was observed that ITPA polymorphisms have impact on hematological changes, including hemoglobin (Hb)-decline during treatment of chronic hepatitis C (CHC) patients with pegylated-interferon (PEG-IFN) plus ribavirin (RBV). OBJECTIVES This study aimed to assess the effect of ITPA and C20orf194 polymorph...
ms یک بیماری خودایمنی مزمن است که در آن میلین نورون های دستگاه عصبی مرکزی (cns) آسیب دیده و آکسون ها تخریب می شوند. تخمین زده می شود که حدود 5/2 میلیون نفر در سراسر جهان به ms مبتلا باشند. ایران در ناحیه ای با شیوع متوسط قرار دارد و آمار ابتلا به آن در کشور رو به افزایش می باشد. ms یک بیماری پیچیده است و تحت تأثیر عوامل محیطی و ژنتیکی متفاوتی می باشد. یکی از داروهایی که برای بیماران ms تجویز می...
background it has been found that itpase deficiency is caused by itpa gene polymorphisms. it was observed that itpa polymorphisms have impact on hematological changes, including hemoglobin (hb)-decline during treatment of chronic hepatitis c (chc) patients with pegylated-interferon (peg-ifn) plus ribavirin (rbv). conclusions in patients with chc, who were treated with peg-ifn plus rbv, hb-decli...
