Intestinal transplant (IT) is one of the least common forms of organ transplant but is increasing both in volume of cases and number of centers performing intestinal transplants, with the busiest centers in North America and Europe. IT can be performed in isolation or as part of a multivisceral transplant (MVT). Intestinal failure either in the form of short gut syndrome or functional bowel problems is the primary indication for IT. The normal post-surgical anatomy can be variable due to both recipient anatomy in regard to amount of residual bowel and status of native vasculature as well as whether the transplant is isolated or part of an multivisceral transplant...

A serious complication to the laparoscopic Roux-en-Y gastric bypass (RYGB) is internal hernia, which can lead to massive bowel necrosis that may result in short bowel syndrome. We determined postprandial enteropancreatic hormonal responses and metabolites in a 22-year-old nondiabetic woman with a history of RYGB experiencing severe internal herniation with widespread bowel necrosis. Extensive resections were performed leaving her with a saliva fistula from the pouch-enteric anastomosis, an intact duodenum, 15 cm of jejunum, 35 cm of ileum, and intact colon...

Rifaximin, a non-systemic antibiotic, is efficacious for the treatment of diarrhoea-predominant irritable bowel syndrome (IBS-D). Given the emerging association between the gut microbiota and IBS, this study examined potential effects of rifaximin on the gastrointestinal microbial community in patients with IBS-D. TARGET 3 was a randomised, double-blind, placebo-controlled, phase 3 study. Patients with IBS-D initially received open-label rifaximin 550 mg 3 times daily (TID) for 2 weeks. Patients who responded to the initial treatment and then relapsed were randomised to receive 2 repeat courses of rifaximin 550 mg TID or placebo for 2 weeks, with each course separated by 10 weeks...

PURPOSE OF REVIEW: Short bowel syndrome (SBS) is a rare disease but with many complications due to intestinal failure, parenteral nutrition and underlying disease. A better prevention, comprehension and treatment could improve the outcome of these patients. RECENT FINDINGS: Recent studies have been published on acute intestinal failure, first cause of SBS, and gives us strategy to avoid extended intestinal resection and thus SBS. There has been progress in the comprehension of intestinal adaptation, characterized by improvements in intestinal absorption, changes on hormonal secretion, development of a hyperphagia and dysbiosis of the gut microbiota...

BACKGROUND: Parenteral nutrition (PN) provides nutrition intravenously; however, this life-saving therapy is associated with significant liver disease. Recent evidence indicates improvement in PN-associated injury in animals with intact gut treated with enteral bile acid (BA), chenodeoxycholic acid (CDCA), and a gut farnesoid X receptor (FXR) agonist, which drives the gut-liver cross talk (GLCT). We hypothesized that similar improvement could be translated in animals with short bowel syndrome (SBS)...

The investigation of the human microbiome is the most rapidly expanding field in biomedicine. Early studies were undertaken to better understand the role of microbiota in carbohydrate digestion and utilization. These processes include polysaccharide degradation, glycan transport, glycolysis, and short-chain fatty acid production. Recent research has demonstrated that the intricate axis between gut microbiota and the host metabolism is much more complex. Gut microbiota—depending on their composition—have disease-promoting effects but can also possess protective properties...

Intestinal adaptation is important for the short bowel syndrome (SBS) patients. Growing evidence has suggested that bile salt dependent lipase (BSDL) not only has the lipolytic activity, but also the immune-modulating and pro-proliferative activities. The purpose of this study was to investigate the effects of BSDL on intestinal adaptive growth and gut barrier function in a rat model of SBS. Twenty-four male Sprague-Dawley rats were randomly divided into three experimental groups: sham group (rats underwent bowel transection and reanastomosis), SBS group (rats underwent 80 % bowel resection), SBS-BSDL group (SBS rats orally administered BSDL)...

Bacteroidetes are the largest phylum of Gram-negative bacteria inhabiting our gastrointestinal tract and are considered the leading players of the healthy state and sophisticated homeostasis safeguarded by gut microbiota. Furthermore, specific roles have been attributed to some Bacteroidetes genera in the development of immune dysregulation, systemic disease such as metabolic syndrome and also neurological disorders. Glycoproteins secretion, short fatty acids imbalance, toxins production and molecular mimicry are only a part of the functions exerted by these commensals interacting with the host...

Insulin resistance is a major risk factor for diseases such as type 2 diabetes and metabolic syndrome. Current methods for management of insulin resistance include pharmacological therapies and lifestyle modifications. Several clinical studies have shown that leguminous plants such as soybeans and pulses (dried beans, dried peas, chickpeas, lentils) are able to reduce insulin resistance and related type 2 diabetes parameters. However, to date, no one has summarized the evidence supporting a mechanism of action for soybeans and pulses that explains their ability to lower insulin resistance...

BACKGROUND: Short bowel syndrome occurs following massive small bowel resection (SBR) and is one of the most lethal diseases of childhood. We have previously demonstrated hepatic steatosis, altered gut microbiome, and increased fat deposition in our murine model of SBR. These novel findings prompted us to investigate potential alterations in glucose metabolism and systemic inflammation following intestinal resection. METHODS: Male C57BL6 mice underwent 50% proximal SBR or sham operation...

AIM: Analogues of several gastrointestinal peptide hormones have been developed into effective medicines for treatment of diseases such as type 2 diabetes mellitus (T2DM), obesity and short bowel syndrome (SBS). In this study, we aimed to explore whether the combination of glucagon-like peptide-1 (GLP-1) and glucagon-like peptide-2 (GLP-2) into a potent co-agonist could provide additional benefits compared to existing monotherapies. METHODS: A short-acting (GUB09-123) and a half-life extended (GUB09-145) GLP-1/GLP-2 co-agonist were generated using solid-phase peptide synthesis and tested for effects on food intake, body weight, glucose homeostasis, and gut proliferation in lean mice and in diabetic db/db mice...

BACKGROUND: Conditions of excess androgen in women, such as polycystic ovary syndrome (PCOS), often exhibit intergenerational transmission. One way in which the risk for PCOS may be increased in daughters of affected women is through exposure to elevated androgens in utero. Hyperandrogenemic conditions have serious health consequences, including increased risk for hypertension and cardiovascular disease. Recently, gut dysbiosis has been found to induce hypertension in rats, such that blood pressure can be normalized through fecal microbial transplant...

Intestinal failure (IF) is the reduction of gut function below the minimum necessary for the absorption of macronutrients and/or water and electrolytes, such that parenteral support (PS) is required to maintain health and/or growth. This article critically revises the gaps in and evidence for providing general nutritional therapy recommendations in the Short Bowel Syndrome-IF population. It addresses the need for an individualized approach, aiming to reduce or even eliminate the need for PS, and emphasizes a need to focus on effects of dietary interventions on the quality of life of these patients...

Intestinal failure (IF) is the inability of the gut to absorb necessary water, macronutrients (carbohydrate, protein, and fat), micronutrients, and electrolytes sufficient to sustain life and requiring intravenous supplementation or replacement. Acute IF (types 1 and 2) is the initial phase of the illness and may last for weeks to a few months, and chronic IF (type 3) from months to years. The challenge of caring for patients with IF is not merely the management of the underlying condition leading to IF or the correct provision of appropriate nutrition or both but also the prevention of complications, whether thromboembolic phenomenon (for example, venous occlusion), central venous catheter-related bloodstream infection, IF-associated liver disease, or metabolic bone disease...

A 45-year-old woman who required lifelong anticoagulation for recurrent thrombosis had her therapeutic choices limited by heparin-induced thrombocytopenia and abnormal pharmacokinetics (greatly reduced absorption) resulting from short gut syndrome from extensive gut resection after mesenteric thrombosis. As an alternative to inconvenient and expensive injections of fondaparinux, personalized dosing of a direct oral anticoagulant was sought using clinical pharmacology techniques. Enteral absorption was ascertained with small test doses of apixaban, and the ability of supraconventional doses to deliver effective concentrations was verified...

Short bowel syndrome occurs following the loss of a large portion of functional intestine and is associated with high morbidity and mortality. The intestine exhibits pronounced diurnal rhythms in glucose absorption and mounts a profound proliferative response following massive small bowel resection. Understanding the molecular pathways that underpin this could yield novel treatment options. Two in vivo models were employed using the nocturnally active Sprague Dawley® rat, namely daytime feeding and massive small bowel resection...
