Crohn's disease (CD) is a multifactorial pathology associated with the presence of adherent-invasive Escherichia coli (AIEC) and NLRP3 polymorphic variants. The presence of intracellular E. coli in other intestinal pathologies (OIP) and the role of NLRP3-inflammasome in the immune response activated by these bacteria have not been investigated. In this(More)
BACKGROUND ST2 has been proposed to be a regulator of inflammation and Th1/Th2 balance. ST2L is the IL-33 membrane receptor and belongs to the IL-1R family. The soluble variant, ST2s, is identical to the extracellular region of ST2L and competes for IL-33 binding, inhibiting receptor signaling. Although ST2s has been associated with inflammatory processes(More)
AIM To correlate circulating soluble ST2 (sST2) levels with the severity of ulcerative colitis (UC) and serum levels of pro-inflammatory cytokines, and to demonstrate the predictive power of sST2 levels for differentiation between active and inactive UC. METHODS We recruited 153 patients: 82 with UC, 26 with Crohn's disease (CD) and 43 disease controls(More)
Small intestinal bacterial overgrowth is common in intestinal failure. Its occurrence relates to alterations in intestinal anatomy, motility, and gastric acid secretion. Its presence may contribute to symptoms, mucosal injury, and malnutrition. Relationships between bacterial overgrowth and systemic sepsis are of potential importance in the intestinal(More)
BACKGROUND AND STUDY AIMS The incidence of oesophageal adenocarcinoma has increased significantly in recent years. While surveillance of people with Barrett's oesophagus, its usual precursor, has been advocated in order to detect dysplasia and early cancer in those considered to be at greatest risk, the impact of such a strategy on survival from oesophageal(More)
Thromboembolism is an extraintestinal manifestation and an important cause of mortality in inflammatory bowel disease (IBD). The risk of thromboembolism appears to be multifactorial and related to mucosal inflammatory activity in most patients. Various laboratory markers such as thrombin activatable fibrinolysis inhibitor (TAFI) levels have been linked with(More)
We investigated myeloid-dendritic cell (DC) marker and Toll-like receptor (TLR)-2 and 4 distributions in ileal samples from Crohn's disease (CD) patients (n = 14) and controls (n = 13). In controls, no TLR-2+ cells were observed, and higher numbers of TLR-4+ and DC-SIGN+ cells (P < 0.01) were detected in ileal samples when compared versus colonic tissues.(More)
Inflammatory bowel diseases (IBD) are inflammatory diseases with a multifactorial component that involve the intestinal tract. The two relevant IBD syndromes are Crohn's disease (CD) and ulcerative colitis (UC). One factor involved in IBD development is a genetic predisposition, associated to NOD2/CARD15 and Toll-like receptor 4 (TLR4) polymorphisms that(More)
Crohn's disease (CD) and ulcerative colitis (UC) are multifactorial diseases with a genetic background. Genes related to the innate immune response have been observed to be involved. Polymorphisms of Toll-like receptor 4 (TLR4) and CARD15/NOD2 are thought to be involved in the pathogenesis of inflammatory bowel disease (IBD). There is no information about(More)
