BACKGROUND Ulcerative colitis (UC) and Crohn's disease (CD) share some pathogenetic features. To provide new steps on the role of altered gene expression, and the involvement of gene networks, in the pathogenesis of these diseases, we performed a genome-wide analysis in 15 patients with CD and 14 patients with UC by comparing the RNA from inflamed and(More)
BACKGROUND Crohn's disease (CD) is a pathologic condition with different clinical expressions that may reflect an interplay between genetics and environmental factors. Recently, it has been highlighted that three genetic markers, NOD2, MHC and MST1, were associated to distinct CD sites, supporting the concept that genetic variations may contribute to(More)
Activation of initiator and effector caspases, mitochondrial changes involving a reduction in its membrane potential and release of cytochrome c (cyt c) into the cytosol, are characteristic features of apoptosis. These changes are associated with cell acidification in some models of apoptosis. The hierarchical relationship between these events has, however,(More)
BACKGROUND Recent GWAs and meta-analyses have outlined about 100 susceptibility genes/loci for inflammatory bowel diseases (IBD). In this study we aimed to investigate the influence of SNPs tagging the genes/loci PTGER4, TNFSF15, NKX2-3, ZNF365, IFNG, PTPN2, PSMG1, and HLA in a large pediatric- and adult-onset IBD Italian cohort. METHODS Eight SNPs were(More)
BACKGROUND Efficacy of erythrocyte-mediated delivery of dexamethasone 21-phosphate in patients with steroid-dependent ulcerative colitis. METHODS Thirty-seven patients with steroid-dependent ulcerative colitis were randomized to infusions of dexamethasone 21-phosphate encapsulated into autologous erythrocytes (n = 19) or to sham infusions (n = 18). Each(More)
Simultaneous analysis of the transcripts of thousands of genes by cDNA microarrays allows the identification of genetic regulatory mechanisms involved in disease pathophysiology. The circadian clock circuitry controls essential cell processes and the functioning of organ systems, which are characterized by rhythmic variations with 24-hour periodicity. The(More)
AIM To investigate the association of single nucleotide polymorphisms (SNPs) of genes involved in the regulation of immune responses, IL33, IL1RL1, IL23R, and IL10, with idiopathic achalasia in an Italian cohort of patients. MATERIALS AND METHODS A panel of eleven polymorphisms were genotyped in 116 unrelated idiopathic achalasic patients and 371 healthy(More)
BACKGROUND The satisfaction perceived by patients with chronic diseases affects clinical outcomes and healthcare costs. Some patients with inflammatory bowel disease (IBD) develop a more severe form requiring biologic therapy. We assessed the quality of care perceived by IBD patients in dedicated centers. METHODS This prospective, cross-sectional,(More)
