BACKGROUND The PTPN22 gene is an important risk factor for human autoimmunity. The aim of this study was to evaluate for the first time the role of the R263Q PTPN22 polymorphism in ulcerative colitis (UC) and Crohn's disease (CD), and to reevaluate the association of the R620W PTPN22 polymorphism with both diseases. METHODS A total of 1677 UC patients,(More)
The aim of this study was to determine the role of the ATG16L1 (rs2241880) and IRGM (rs13361189 and rs4958847) genes polymorphism in Crohn's disease (CD) and ulcerative colitis (UC). Our study included 557 CD and 425 UC patients and 672 ethnically matched Spanish controls and a meta-analysis with the data published to date. The polymorphisms were genotyped(More)
Impaired innate inflammatory response has a key role in the Crohn's disease (CD) pathogenesis. The aim of this study was to investigate the possible role of the TLR10-TLR1-TLR6 gene cluster in CD susceptibility. A total of 508 CD patients (284, cohort 1 and 224, cohort 2) and 576 controls were included. TLR10-TLR1-TLR6 cluster single-nucleotide(More)
OBJECTIVES The safety of thiopurines and anti-tumor necrosis factor-α (TNF-α) drugs during pregnancy remains controversial, as the experience with these drugs in this situation is limited. Our aim is to assess the safety of thiopurines and anti-TNF-α drugs for the treatment of inflammatory bowel disease (IBD) during pregnancy. METHODS Retrospective,(More)
To assess the influence of inducible and endothelial nitric oxide synthase gene (NOS2A and NOS3) polymorphisms in susceptibility to Crohn's disease (CD) and ulcerative colitis (UC). A total of 505 inflammatory bowel disease (IBD) patients (221 with UC and 284 with CD) and 332 ethnically matched controls were studied. Patients and controls were genotyped by(More)
Infliximab (IFX) is a valid treatment for Crohn's disease (CD), but a relevant percentage of patients do not benefit from this therapy. In the Japanese population, the response to IFX was associated with markers in the TNF receptor superfamily 1A (TNFRSF1A) and 1B (TNFRSF1B) genes. We aimed to replicate the association previously described in the Japanese(More)
The aim of this work was to investigate the possible influence of the recently described CT60 A/G dimorphism of the CTLA4 (cytotoxic T-lymphocyte antigen 4) gene in the susceptibility to two different autoimmune inflammatory intestinal disorders, inflammatory bowel disease (IBD) and celiac disease. We analyzed a case-control cohort composed of 528 Spanish(More)
The aim of this study was to assess the possible association between the protein tyrosine phosphatase non-receptor 22 (PTPN22) gene 1858C-->T (rs2476601, encoding R620W) polymorphism and inflammatory bowel disease (IBD). Our study population consisted of 1113 IBD [544 ulcerative colitis (UC) and 569 Crohn's disease (CD)] patients and 812 healthy subjects.(More)
AC choppers are a family of ac-to-ac power converters that can be derived from the traditional dc-to-dc converters. Research activity in this kind of converter has recently increased in applications for power conditioning—such as voltage control in the distribution system and power flow control in the transmission system—as an alternative for the dc-link(More)
