Components of the metabolic syndrome (MetS), including abdominal obesity, low-grade chronic systemic inflammation, altered glucose metabolism, dyslipidemia and high blood pressure, are major threats to healthy aging in modern societies. The connection between MetS components and gut microflora is now acknowledged and multiple therapeutic strategies have been proposed to change the composition of the gut microbiota in order to promote optimal metabolic health. Prebiotics have the ability to favour growth of beneficial bacteria, especially short-chain fatty-acids (SCFA) producers...

James F White
This article outlines the proposed 'syntrophic imbalance hypothesis' for etiology of bacterial endoparasitism diseases. This hypothesis involves microbes (archaea and bacteria) that exist in human body biofilms in syntrophic associations, where bacteria ferment nutrients to produce short chain fatty acids (SCFAs) that are used by methanogenic archaeons to produce methane. Overgrowth of archaea on human tissues (e.g., in association with intestines, teeth or lungs) results in excessive removal of SCFAs from the biofilms and this triggers bacteria in the free-living biofilm state to convert to the endoparasitic state and become intracellular in host cells where they incite inflammation and disease...

Parenteral nutrition (PN) provides life-saving nutritional support in situations where caloric supply via the enteral route cannot cover the necessary needs of the organism. However, it does have serious adverse effects, including parenteral nutrition-associated liver disease (PNALD). The development of liver injury associated with PN is multifactorial, including non-specific intestine inflammation, compromised intestinal permeability, and barrier function associated with increased bacterial translocation, primary and secondary cholangitis, cholelithiasis, short bowel syndrome, disturbance of hepatobiliary circulation, lack of enteral nutrition, shortage of some nutrients (proteins, essential fatty acids, choline, glycine, taurine, carnitine, etc...

REVIEW
Nicholas D Embleton, Stefan P Zalewski
Necrotising enterocolitis (NEC) is a devastating disease with significant mortality and serious adverse outcomes in at least 50% including short gut and poor neurodevelopment. Research and management are complicated by a lack of robust clinical markers, and without histological confirmation, there is a risk of both underdiagnosis and overdiagnosis. Interunit variations in the thresholds for surgical referral, laparotomy and postmortem rates mean the actual incidence is difficult to determine, especially because the histological term 'NEC' is used in practice to describe a heterogeneous clinical syndrome...

OBJECTIVE: To determine the effects of exogenous glucagon-like peptide-2 (GLP-2), with or without massive distal bowel resection, on adaptation of jejunal mucosa, enteric neurons, gut hormones and tissue reserves in rats. BACKGROUND: GLP-2 is a gut hormone known to be trophic for small bowel mucosa, and to mimic intestinal adaptation in short bowel syndrome (SBS). However, the effects of exogenous GLP-2 and SBS on enteric neurons are unclear. METHODS: Sprague Dawley rats were randomized to four treatments: Transected Bowel (TB) (n = 8), TB + GLP-2 (2...

Central venous access devices (CVADs) form an important component of modern paediatric healthcare, especially for children with chronic health conditions such as cancer or gastrointestinal disorders. However device failure and complications rates are high.Over 2½ years, a child requiring parenteral nutrition and associated vascular access dependency due to 'short gut syndrome' (intestinal failure secondary to gastroschisis and resultant significant bowel resection) had ten CVADs inserted, with ninesubsequently failing...

OBJECTIVE: To investigate immune cells of the colonic mucosa and fecal short-chain fatty acids (SCFAs) in treatment-naive patients with a clinically isolated syndrome (CIS) or early relapsing MS. METHODS: In this cross-sectional proof-of-concept study, we obtained mucosal specimens during ileocolonoscopy from 15 untreated patients with CIS/MS and 10 controls. Mucosal immune cells were analyzed by FACS, and gas chromatography-mass spectrometry measurements of stool samples served to determine SCFA...

REVIEW
Evren Doruk Engin
Obesity and metabolic syndrome is a multisystemic disorder, that is characterized by excess caloric intake and spillover lipotoxicity caused by ectopic lipid accumulation in non-adipose tissues. Low grade chronic inflammation and insulin resistance are the hallmarks of the disorder, which further aggravate the condition. Gut microbiota constitutes an indispensible part of human superorganism's energy harvesting apparatus. The dynamic composition of microbiota changes with age, life style and host metabolic background...

OBJECTIVE: Glucagon-like peptides (GLPs) are secreted from enteroendocrine cells in response to nutrients and bile acids and control metabolism via actions on structurally-related yet distinct G protein coupled receptors. GLP-1 regulates gut motility, appetite, islet function, and glucose homeostasis, whereas GLP-2 enhances intestinal nutrient absorption. GLP-1R agonists are used to treat diabetes and obesity, and a GLP-2R agonist is approved to treat short bowel syndrome. Unexpectedly, reports of gallbladder disease have been associated with the use of both GLP-1R and GLP-2R agonists and after bariatric surgery, although the mechanisms remain unknown...

Primary IF can be due to impaired gut length or impaired gut function; short bowel syndrome (SBS) is the leading cause of IF. In IF patients complete enteral starvation should be avoided whenever possible and enteral/oral nutrition (EN/ON) should be employed at the maximum tolerated amount in each phase of the clinical evolution of IF. Intraluminal nutrients have stimulatory effects on epithelial cells and on trophism that enhance intestinal adaptation. Areas covered: Evidence for nutritional interventions in pediatric IF is limited and of poor quality...

We investigated the effect of a high fructose diet (HFD) on Sprague Dawley rats and the impact of a synbiotic composed of Lactobacillus fermentum CECT5716 and fructooligosaccharides. Feeding the HFD for 5 weeks resulted in liver steatosis and insulin resistance but not obesity. These changes were associated with increased production of short-chain fatty acids and increased Bacteroidetes in feces, with an augmented Bacteroidetes/Firmicutes ratio, among other changes in the microbiota. In addition, barrier function was weakened, with increased LPS plasma levels...

Perinatal malnutrition is associated with low birth weight and an increased risk of developing metabolic syndrome in adulthood. Modification of food intake (FI) regulation was observed in adult rats born with intrauterine growth retardation induced by maternal dietary protein restriction during gestation and maintained restricted until weaning. Gastrointestinal peptides and particularly cholecystokinin (CCK) play a major role in short-term regulation of FI by relaying digestive signals to the hindbrain via the vagal afferent nerve (VAN)...

AIM OF THE STUDY: To report the current activity of intestinal transplantation in Europe (EU) and Unites States of America (USA), underlining outcomes in the last 5 years and discussing possible trends. PATIENTS AND METHODS: Data review of results was performed through analysis of ITR and UNOS registries, Eurotransplant and newsletter transplant reports, congress abstracts, international published literature, personal communications and hospital web sites. RESULTS: The absence in Europe of a sole organization collecting donors and the presence of many low-volume centers (less than 5 cases/year) makes the difference with USA: in the last 5 years (2010-2014), 222 intestinal/multivisceral transplants have been performed in EU countries (most of them in the UK), while in USA, the number of transplants achieved 634 procedures in the same period of time...

BACKGROUND AND AIM: Short bowel syndrome (SBS) is a common cause of intestinal failure and can be divided into three types depending on intestinal anatomy. Gut dysbiosis has been observed in pediatric SBS patients and is associated with impaired outcome. Little is known about the changes in gut microbiota of adult SBS patients. Therefore, we aim to characterize the fecal microbiota of adult patients with different types of SBS. METHODS: Fifteen fecal samples from healthy controls and adult patients with type II or type III SBS were collected (five in each group)...

The gut microbiota has the ability to modulate host energy homeostasis, which may regulate metabolic disorders. Functional oligosaccharide may positively regulate the intestinal microbiota. Therefore, effects of α-galactooligosaccharides (α-GOS) from chickpea on high-fat-diet (HFD)-induced metabolic syndrome and gut bacterial dysbiosis were investigated. After 6 weeks of intervention, HFD led to significant increases in levels of blood glucose, total cholesterol, triglyceride, glycated serum protein, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol of mice compared to normal-chow-fed mice...

BACKGROUND&AIMS: The classical ketogenic diet (KD) is a high-fat, very low-carbohydrate normocaloric diet used for drug-resistant epilepsy and Glucose Transporter 1 Deficiency Syndrome (GLUT1 DS). In animal models, high fat diet induces large alterations in microbiota producing deleterious effects on gut health. We carried out a pilot study on patients treated with KD comparing their microbiota composition before and after three months on the diet. METHODS: Six patients affected by GLUT1 DS were asked to collect fecal samples before and after three months on the diet...
