AIM: To explore the effects of abdominal surgery and interleukin-1 signaling on antimicrobial defense in a model of postoperative ileus. METHODS: C57BL/6 and Interleukin-1 receptor type I (IL-1R1) deficient mice underwent intestinal manipulation to induce POI. Expression of mucosal IL-1α, IL-1β and IL-1R1 and several antimicrobial peptides and enzymes were measured by quantitative PCR or ELISA, western blotting or immunohistochemistry. Bacterial overgrowth was determined by fluorescent in-situ hybridization and counting of jejunal luminal bacteria...

PURPOSE: The growing population of survivors after colon cancer warrants increased attention to the long-term outcome of surgical treatment. The change in bowel anatomy after resection disrupts normal gastrointestinal function and may cause symptoms. Thus, many patients surviving colon cancer have to cope with bowel dysfunction for the rest of their lives. We here aim to provide an overview of the literature on this topic. METHODS: We review long-term functional outcomes of surgical treatment for colon cancer, the underlying pathology, and treatment options...

The effect of probiotics on small intestinal bacterial overgrowth (SIBO) in irritable bowel syndrome (IBS) has never been studied so far. In this prospective trial, five patients with IBS and SIBO and 21 patients with IBS without SIBO were administered an oral capsule containing Saccharomyces boulardii, Bifidobacterium lactis, Lactobacillus acidophilus, and Lactobacillus plantarum (Lactolevure® ) every 12 h for 30 days. SIBO was defined by quantitative culture of the third part of the duodenum; IBS was defined by the Rome III criteria...

BACKGROUND: Small intestinal bacterial overgrowth (SIBO) is a condition characterised by symptoms similar to pancreatic exocrine insufficiency (PEI) in chronic pancreatitis patients. SIBO is thought to complicate chronic pancreatitis in up to 92% of cases; however, studies are heterogeneous and protocols non-standardised. SIBO may be determined by measuring lung air-expiration of either hydrogen or methane which are by-products of small bowel bacterial fermentation of intraluminal substrates such as carbohydrates...

Background/Aims: Fructose malabsorption (FM) mimics symptoms of irritable bowel syndrome (IBS), and its prevalence has increased. Diagnosing FM in IBS is challenging because of its overlap with small intestinal bacterial overgrowth (SIBO). We assessed the prevalence of FM by comparing patients with IBS with asymptomatic control individuals after excluding SIBO using the glucose hydrogen breath test (HBT). Methods: Patients diagnosed with IBS and asymptomatic control individuals were enrolled prospectively...

Marfan syndrome is an autosomal dominant disorder involving mutation in the FBN1 gene, which encodes fibrillin-1, a protein critical to maintain the integrity of connective tissue. A mutation in this gene can affect multiple organ systems, but it is not classically associated with gastrointestinal complications. We describe a man with Marfan syndrome with multiple small bowel diverticula leading to small intestinal bacterial overgrowth and recurrent small bowel perforations.

BACKGROUND: Gut dysbiosis associated with the use of proton-pump inhibitors (PPIs) has been found to lead to the occurrence of infectious and inflammatory adverse events. A longitudinal observational cohort study has demonstrated the heightened risk of death associated with PPI use. SUMMARY: We evaluated meta-analyses to determine the association between PPI use and infectious and inflammatory diseases. Meta-analyses showed that PPI use is a potential risk for the development of enteric infections caused by Clostridium difficile, as well as small intestinal bacterial overgrowth, spontaneous bacterial peritonitis, community-acquired pneumonia, hepatic encephalopathy, and adverse outcomes in inflammatory bowel disease...

BACKGROUND: The mechanisms by which intestinal bacteria impact liver diseases remain poorly understood. The aim of this study was to develop a mouse model of small-bowel bacterial overgrowth and to determine its impact on hepatobiliary injury. MATERIALS AND METHODS: A jejunal self-filling blind loop (SFBL) was created in C57BL/6 mice. Three weeks after surgery, the mice were euthanized, and bacterial cultures of luminal content of the loop and extraintestinal tissues were performed...

Prolonged suppression of gastric acid secretion by proton pump inhibitors (PPIs) may alter the bacterial microbiota of the upper gastrointestinal tract and lead to small bowel bacterial overgrowth (SBBO). Published reports have shown conflicting results on the association between PPI therapy and risk of SBBO development. We evaluated whether long-term PPI treatment is associated with presence of SBBO as determined by breath hydrogen (H2) and methane (CH4) excretion. We also assessed the differences in H2 / CH4 excretion patterns in patients taking PPI compared with those not taking the medication and searched for the potential predictors of a positive breath test result...

Exocrine pancreatic insufficiency (EPI) is one of the possible mechanisms of fat maldigestion following gastric surgery, together with reduced food intake, loss of gastric reservoir, small bowel bacterial overgrowth and rapid small bowel transit. Oral pancreatic enzyme replacement therapy (PERT) is the mainstay of treatment for EPI. The efficacy and safety of pancreatic enzyme substitution in patients following gastric resection remains unclear. This review article summarizes relevant studies addressing PERT after gastric resection...

The important role of microfilaria (worms) in human and animal disease remains an area of key disagreement between the naturopathic and allopathic physicians. While microfilaria infections are rampart in undeveloped countries, they rarely rise to identification as a cause of disease in Western countries. New research studies in the diagnosis and treatment of SIBO (Small Intestinal Bacterial Overgrowth) and (IBD) Inflammatory Bowel Diseases of ulcerative colitis, Crohn's Disease and microcytic colitis may make both sides equally correct...

Celiac disease is an immune-mediated enteropathy triggered by gluten that affects genetically predisposed individuals, typically causing intestinal symptoms and malabsorption. Diagnosis requires stepwise evaluation with anti-tissue transglutaminase IgA and histologic analysis of the small bowel. Strict adherence to a gluten-free diet is the primary treatment. Patients with symptoms thought to be related to gluten but without evidence of celiac disease are difficult to diagnose and treat. Consider first advising general nutritional improvements...

We describe 3 patients with short bowel syndrome who had persistently elevated serum methylmalonic acid (MMA) levels while being treated for vitamin B12 deficiency. Following treatment for presumed small bowel bacterial overgrowth, MMA levels normalized. Among patients with short bowel syndrome, MMA levels may have limited specificity for vitamin B12 deficiency.

BACKGROUND: Mortality from chronic liver disease is rising exponentially. The liver is intimately linked to the gut via the portal vein, and exposure to gut microbiota and their metabolites translocating across the gut lumen may impact upon both the healthy and diseased liver. Modulation of gut microbiota could prove to be a potential therapeutic target. AIM: To characterise the changes in the gut microbiome that occur in chronic liver disease and to assess the impact of manipulation of the microbiome on the liver...

BACKGROUND: Though pathogenesis of non-alcoholic steatohepatitis (NASH) is unclear, association with small intestinal bacterial overgrowth [SIBO] and fecal dysbiosis is suggested. We evaluated SIBO in NASH using quantitative jejunal aspirate culture (conventional criteria: ≥ 105 colony forming unit (CFU)/mL and newer cutoff ≥ 103  CFU/mL) and glucose hydrogen breath test. METHODS: Thirty-eight patients with NASH (age 37.5 years, range 20-54, 9, 24% female), diagnosed by ultrasonography, alanine aminotransferase >1...

BACKGROUND: Small intestinal bacterial overgrowth (SIBO) has been associated with anatomical and motility-related abnormalities. Specifically, obesity has been postulated to alter small bowel motility, leading to SIBO. AIMS: (i) Assess the prevalence of SIBO in obesity; (ii) determine the relationship of obesity and SIBO, using small bowel transit time (SBTT) and pH; (iii) profile the gut microbiome in obese and non-obese patients with SIBO. METHODS: Thirty consecutive participants referred for SIBO underwent lactulose breath tests (LBTs) and wireless motility capsule (WMC) studies...
