Mucosal T cells: mediators or guardians of inflammatory bowel disease?

2003

Because the mucosal immune system is continuously exposed to a myriad of potentially harmful environmental antigens, it frequently reacts with antiinflammatory/regulatory T cell responses driven by TGF-β-producing T H 3 cells and IL-10-producing regulatory T cells. Intestinal inflammation in patients with inflammatory bowel diseases is thought to result from an overwhelming uncontrolled activation of the mucosal immune system induced by antigens of the normal luminal flora in genetically susceptible individuals. Inflammatory bowel disease appears to be mediated by subsets of CD4 + T lymphocytes or NK T cells secreting high levels of proinflammatory cytokines such as TNF-α. The increased exp…

Involvement of IL-6 in the Pathogenesis of Inflammatory Bowel Disease and Colon Cancer

2005

Inflammatory bowel disease (IBD), which consists of Crohn’s disease and ulcerative colitis, is defined as a chronic inflammation of the gastrointestinbal tract. The etiopathogenetic mechanisms underlying the development of IBD are still not completely understood, and the therapeutic strategies used thus far have been limited to mostly evidence-based principles. There is growing evidence that the pro-inflammatory cytokine interleukin (IL)-6 plays a crucial part in the uncontrolled intestinal inflammatory process, which is a main characteristic of IBD. There is elevated production of IL-6 and its soluble receptor (sIL-6R) by intestinal macrophages and CD4+ T-cells. The increased formation of …

Association of mechanical bowel preparation with oral antibiotics and anastomotic leak following left sided colorectal resection: an international, m…

2018

INTRODUCTION: The optimal bowel preparation strategy to minimise the risk of anastomotic leak is yet to be determined. This study aimed to determine whether oral antibiotics combined with mechanical bowel preparation (MBP+Abx) was associated with a reduced risk of anastomotic leak when compared to mechanical bowel preparation alone (MBP) or no bowel preparation (NBP).METHODS: A pre-planned analysis of the European Society of Coloproctology (ESCP) 2017 Left Sided Colorectal Resection audit was performed. Patients undergoing elective left sided colonic or rectal resection with primary anastomosis between 1 January 2017 and 15 March 2017 by any operative approach were included. The primary out…

Small bowel gastrointestinal stromal tumor presenting with gastrointestinal bleeding in patient with type 1 Neurofibromatosis: Management and laparos…

2021

Highlights • A multidisciplinary team is mandatory for the correct management of hemorrhagic GIST and its complications. • There is a well-known association between type 1 Neurofibromatosis and GIST. • Type 1 Neurofibromatosis-GIST and sporadic GIST have different behaviour. • In case of localised and resectable GIST surgical treatment is the mainstay. • Laparoscopic approach, if performed correctly, is safe and effective with better short-term outcomes then open surgery.

Laparoscopic treatment of mesenteric avulsion and intestinal perforation after blunt abdominal trauma: A report of a case

2020

Highlights • Intestinal injuries are quite involved in non-penetrating abdominal trauma after liver and spleen. • The incidence of small bowel injury after blunt abdominal trauma has increased nowadays, since high-energy transfer impacts producing large abdominal wall displacements are more frequent, such as car crash. • We report a case of a 49-year-old Caucasian woman, victim of a violent car crash, resulting in multiple small bowel perforations and mesenteric avulsion treated with laparoscopic approach. • Laparoscopy is a safe and feasible tool in selected patients with blunt abdominal trauma, both for diagnosis and treatment. • The prerequisites for applying mini invasive approach are b…

Function and Sacrality of Philoctetes' Bow

2019

El arco de Filoctetes, como objeto simbólico importante y sagrado de la tragedia homónima de Sófocles, ha sido estudiado en numerosas ocasiones. A pesar de ello, su importancia como arma sagrada merece una revisión que atienda a los contextos religioso y épico de los que bebió Sófocles. Según la teoría tradicional, esta sacralidad deriva de la proveniencia divina del arco, que procede de Heracles. Con todo, en algunos pasajes podría explicarse mejor por la importancia que, en determinados contextos religiosos, adquirían ciertos objetos venerables que eran considerados también sagrados.

Dense genotyping of immune-related disease regions identifies nine new risk loci for primary sclerosing cholangitis

2013

To access publisher's full text version of this article click on the hyperlink at the bottom of the page Primary sclerosing cholangitis (PSC) is a severe liver disease of unknown etiology leading to fibrotic destruction of the bile ducts and ultimately to the need for liver transplantation. We compared 3,789 PSC cases of European ancestry to 25,079 population controls across 130,422 SNPs genotyped using the Immunochip. We identified 12 genome-wide significant associations outside the human leukocyte antigen (HLA) complex, 9 of which were new, increasing the number of known PSC risk loci to 16. Despite comorbidity with inflammatory bowel disease (IBD) in 72% of the cases, 6 of the 12 loci sh…

Impact of antithrombin III on hepatic and intestinal microcirculation in experimental liver cirrhosis and bowel inflammation: An in vivo analysis

2005

AIM: To analyze the hepatic and intestinal microcirculation in an animal model of liver cirrhosis and inflammatory bowel disease (IBD) and to characterize the anti-inflammatory action of antithrombin III (ATIII) on leukocyte kinetics and liver damage. METHODS: Hepatic and intestinal microcirculation was investigated by intravital videomicroscopy. Standardized models of experimental chronic liver cirrhosis and bowel inflammation were employed. Animals were divided into four groups (n = 6/group): controls, animals with cirrhosis, animals with cirrhosis and IBD, animals with cirrhosis and IBD treated with ATIII. RESULTS: Cirrhosis facilitated leukocyte rolling and sticking in hepatic sinusoids…

Cancer in Elderly Onset Inflammatory Bowel Disease: A Population-Based Study.

2016

IF 10.383; International audience; OBJECTIVES: Cancer may be a complication of inflammatory bowel disease (IBD) or its treatment. In elderly onset IBD patients the risk of malignancy is of particular concern. We studied this risk in a population-based cohort of elderly onset IBD patients.METHODS: In a French population-based cohort, we identified 844 patients aged >60 years at IBD diagnosis from 1988 to 2006, including 370 Crohn's disease (CD) and 474 ulcerative colitis (UC). We compared incidence of cancer among IBD patients with that observed in the French Network of population-based Cancer Registries (FRANCIM). Confidence interval (CI) was estimated assuming a Poisson-specific law for ra…
