BACKGROUND & AIMS: CD36 has immuno-metabolic actions and is abundant in the small intestine on epithelial, endothelial and immune cells. We examined the role of CD36 in gut homeostasis using mice null for CD36 (CD36KO) and with CD36 deletion specific to enterocytes (Ent-CD36KO) or endothelial cells (EC-CD36KO). METHODS: Intestinal morphology was evaluated using immunohistochemistry and electron microscopy (EM). Intestinal inflammation was determined from neutrophil infiltration and expression of cytokines, toll-like receptors and COX-2...

BACKGROUND: Enteric neural stem/progenitor cells (ENSCs) offer an innovative approach to treating Hirschsprung disease (HSCR) and other enteric neuropathies. However, postnatal-derived human ENSCs have not been thoroughly characterized and their behavior in the embryonic and postnatal intestinal environment is unknown. METHODS: ENSCs were isolated from the intestines of 25 patients undergoing bowel resection, including 7 children with HSCR. Neuronal differentiation and proliferation of ENSCs from submucosal and myenteric plexuses from patients with and without HSCR were characterized...

Liver allocation in Eurotransplant is complex as allocation rules need to follow not only the guidelines of the European Commission but also the specific regulations of each of the 7 Eurotransplant countries with active liver transplant programs. Thirty-eight liver transplant centers served a population of about 135 million in 2015. Around 1600 deceased donor livers are transplanted annually. The number of deceased organ donors remains stable but donor age is increasing. Nevertheless, liver utilization rates are unchanged at around 80%...

Thrombotic complications are a significant source of morbidity and mortality following hematopoietic stem cell transplants. Among them, transplant-associated thrombotic microangiopathy (TA-TMA) is a well-recognized syndrome that can affect various organ systems. Its etiology is related to endothelial injury accompanied by complement activation. As many of the signs and symptoms of the disease are also encountered in other complications following hematopoietic stem cell transplant, it can often be difficult to establish the diagnosis based on clinical data alone...

AIM: To investigate the incidence, risk factors and clinical outcomes of acute antibody-mediated rejection (ABMR) after intestinal transplantation (ITx). METHODS: A retrospective single-center analysis was performed to identify cases of acute ABMR after ITx, based on the presence of donor-specific antibody (DSA), acute tissue damage, C4d deposition, and allograft dysfunction. RESULTS: Acute ABMR was identified in 18 (10.3%) out of 175 intestinal allografts with an average occurrence of 10 d (range, 4-162) after ITx...

BACKGROUND: Children with intestinal failure (IF) depend on parenteral nutrition (PN). The goal in the treatment of IF is to wean children off PN through intestinal rehabilitation (IR). Although the healthcare burden of IF is enormous, to our knowledge there has been no previous cost-effectiveness analysis in pediatric IF including IR. OBJECTIVE: We sought to determine the cost-effectiveness of IR in terms of costs and life-years. DESIGN: We simulated the treatment of IF in children in a discrete-event model...

Intestine and intestine-liver transplant remains important in the treatment of intestinal failure, despite decreased morbidity associated with parenteral nutrition. In 2015, 196 new patients were added to the intestine transplant waiting list, with equal numbers waiting for intestine and intestine-liver transplant. Among prevalent patients on the list at the end of 2015, 63.3% were waiting for an intestine transplant and 36.7% were waiting for an intestine-liver transplant. The pretransplant mortality rate decreased dramatically over time for all age groups...

Aim Short bowel syndrome (SBS) is the leading cause of intestinal failure (IF) in the pediatric population. Our aim was to review long-term outcome of ultrashort bowel syndrome (USBS) in an Intestinal Rehabilitation Unit (IRU). Patients and Methods Retrospective study of patients with USBS (defined as < 10 cm of remnant small bowel) treated between 2000 and 2015. Demographic data, clinical, and treatment variables including parenteral nutrition (PN), surgical techniques, and intestinal transplantation (IT) were analyzed...

Michael E Höllwarth
Extensive loss of small bowel in all age groups has significant morbidity and mortality consequences. Despite the astonishing ability of the small bowel to compensate for an extensive loss, long-term parenteral nutrition and enteral nutrition, tailored to the need of the patients in relation to the missing intestinal regions is needed. Organ-preserving surgical intervention becomes necessary in patients with a very short intestinal transit time and in an other group of patients with impaired propulsive peristalsis...

BACKGROUND: Splenic abscesses are rare entities; reports are commonly described in immunocompromised patients (72%) as: hematologic diseases, diabetes, endocarditis, acquired immunodeficiency syndrome, transplant patients and subjects who had abdominal trauma or splenic infarction. The main and most serious complication is the abscess rupture into the peritoneal cavity or adjacent organs (stomach or colon), which determines hemodynamic instability or septic state. CLINICAL CASE: Fifty-year-old man, who was admitted at Emergency Room due eight days' progressive, oppressive, and current pain; intensity 4/10, irradiated at hemi-back, which was higher intensity during the standing and decreased at supine position...

BACKGROUND: Intestinal ischemia is observed in conditions such as mesenteric ischemia, or during traumatic events such as intestinal transplantation. Intestinal ischemia leads to pathophysiological disruptions that present as increased fluid secretion into the intestinal lumen. We propose a novel method to detect real-time ischemic injury that is employed in an in vitro model that is applicable to intestinal transplantation. STUDY DESIGN: Small intestine segments from rats were procured...

NK cells, which contribute to immune defense against certain viral infections and neoplasia, are emerging as modifiers of chronic immunologic diseases including transplant rejection and autoimmune diseases. Immunobiology and genetic studies have implicated NK cells as a modifier of Crohn's disease, a condition often treated with thiopurine agents such as 6-mercaptopurine (6-MP). Here, we demonstrate that thiopurines mediate NK cell apoptosis via a caspase 3 and 9 inclusive pathway, and that this process is triggered by thiopurine-mediated inhibition of Rac1...

In view of the growing importance attached to the gut microbiota in preventive medicine and treatment, it would seem essential to identify and analyse the modalities of its representation in a psychosocial approach. In the first part of this article, we will discuss the renewal of representations of the digestive tract brought about by scientific discourse on the gut microbiota, mainly regarding the anthropological status of the intestines and faeces. Then in the second part we will focus on ways of taking advantage of the variable nature of the microbiota by food choices, and we will also focus on therapeutic approaches that use transplantations of faecal matter, and the ensuing loss of privacy entailed (an anthropological notion of defil)...

Although the presence of an intestinal flora has been known for a long time, the discovery of the role of gut microbiota in human health and disease has been widely recognized as one of the most important advances in the recent years. Chronic diseases may result from dysbiosis, i.e. a disruption of the balance within the bacterial population hosted by the human body. These developments open new prospects in terms of prevention and treatment, including the design of adapted diets, the development of functional foods and fecal transplantation...

BACKGROUND: Colitis-associated cancer (CAC) is caused by chronic intestinal inflammation and often results from refractory inflammatory bowel disease (IBD). Stress response proteins Cirp and heat shock protein A4 are involved in the refractory clinical course and development of CAC. RNA-binding motif protein 3 (RBM3) is induced in response to various stresses and is upregulated in several cancers. However, the role of RBM3 in CAC is unclear. METHODS: We assessed RBM3 expression and function in 263 human intestinal mucosa samples from patients with IBD and in Rbm3-deficient (Rbm3) mice...

: Bacterial communities from subjects treated for recurrent Clostridium difficile infection (rCDI) by fecal microbiota transplantation (FMT), using either heterologous donor stool samples or autologous stool samples, were characterized by Illumina next-generation sequencing. As previously reported, the success of heterologous FMT (90%) was superior to that of autologous FMT (43%) (P = 0.019), and post-FMT intestinal bacterial communities differed significantly between treatment arms (P < 0...

Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease with detrimental sequela. In many patients, PSC progresses to end-stage liver disease and hepatobiliary cancer. There is no medical therapy that is proven to halt or reverse the progression of PSC. Approximately 70 to 80% of PSC patients have inflammatory bowel disease, usually ulcerative colitis. The etiology of PSC is poorly understood. Several lines of evidence suggest that the intestinal microbiota plays an important role in the etiopathogenesis of PSC...

In 1968, Wilmore and Dudrick reported an infant sustained by parenteral nutrition (PN) providing a potential for survival for children with significant intestinal resections. Increasing usage of TPN over time led to some patients developing Intestinal Failure Associated Liver Disease (IFALD), a leading cause of death and indication for liver/intestinal transplant. Over time, multi-disciplinary teams called Intestinal Rehabilitation Programs (IRPs) began providing meticulous and innovative management. Usage of alternative lipid emulsions and lipid minimization strategies have resulted in the decline of IFALD and an increase in long-term and transplant-free survival, even in the setting of ultrashort bowel (< 20 cm)...

Regulatory T (T reg) cell deficiency causes lethal, CD4(+) T cell-driven autoimmune diseases. Stem cell transplantation is used to treat these diseases, but this procedure is limited by the availability of a suitable donor. The intestinal microbiota drives host immune homeostasis by regulating the differentiation and expansion of T reg, Th1, and Th2 cells. It is currently unclear if T reg cell deficiency-mediated autoimmune disorders can be treated by targeting the enteric microbiota. Here, we demonstrate that Foxp3(+) T reg cell deficiency results in gut microbial dysbiosis and autoimmunity over the lifespan of scurfy (SF) mouse...
