INTRODUCTION: It seems that there is a relationship between small intestinal bacterial overgrowth (SIBO) and non-alcoholic fatty liver disease (NAFLD). The main objective of this study was to evaluate the prevalence of SIBO among NAFLD patients. METHODS: In this descriptive-analytical cross-sectional study, 98 eligible NAFLD patients were evaluated for SIBO using hydrogen breath test (HBT). They were divided into SIBO-positive and SIBO-negative groups. Demographic, clinical, and laboratory data were obtained...

Fecal microbiota transplantation (FMT) is effective in recurrent Clostridium difficile infection (rCDI). Knowledge of the safety and efficacy of FMT treatment in immune deficient patients is scarce. FMT has been suggested as a potential method for an increasing number of new indications besides rCDI. Among our FMT-treated rCDI patients, we reviewed those with major comorbidities: two human immunodeficiency virus patients, six haemodialysis patients, two kidney transplant patients, two liver transplant patients and a patient with chronic lymphatic leukaemia...

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: ≥ 10(5) colony forming unit (CFU)/mL and newer cutoff ≥ 10(3) 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...

Infections account for significant morbidity and mortality in liver cirrhosis and most are related to the gut microbiome. Fecal dysbiosis, characterized by an overgrowth of potentially pathogenic bacteria and a decrease in autochthonous non-pathogenic bacteria, becomes prominent with the progression of liver cirrhosis. In cirrhotic patients, disruption of the intestinal barrier causes intestinal hyperpermeability (i.e. leaky gut), which is closely related to gut dysmotility, dysbiosis and small intestinal bacterial overgrowth and may induce pathological bacterial translocation...

Complications arising from antibiotic-resistant bacteria are becoming one of the key issues in modern medicine. Members of drug-resistant Enterobacteriaceae spp. include opportunistic pathogens (e.g., Salmonella spp.) that are among the leading causes of morbidity and mortality worldwide. Overgrowth of these bacteria is considered a hallmark of intestinal dysbiosis. Microcins (small antimicrobial peptides) produced by some gut commensals can potentially cure these conditions by inhibiting these pathogens and have been proposed as a viable alternative to antibiotic treatment...

Functional dyspepsia is a highly prevalent disease, with significant impacts on patients' quality of life and economic robustness of health care systems worldwide. It constitutes a constellation of symptoms located in the gastro duodenal region while its pathogenesis remains poorly understood. Accumulating evidence suggest that small intestinal bacterial overgrowth is associated with the etiology of functional gastrointestinal disorders. We herein present the hypothesis that a causal link between small intestinal bacterial overgrowth and functional dyspepsia might exist...

Intestinal immunity exists as a complex relationship among immune cells, epithelial cells, and microbiota. CCR6 and its ligand-CCL20 are highly expressed in intestinal mucosal tissues, such as Peyer's patches (PPs) and isolated lymphoid follicles (ILFs). In this study, we investigated the role of the CCR6-CCL20 axis in intestinal immunity under homeostatic conditions. CCR6 deficiency intrinsically affects germinal center reactions in PPs, leading to impairments in IgA class switching, IgA affinity, and IgA memory B cell production and positioning in PPs, suggesting an important role for CCR6 in T-cell-dependent IgA generation...

OBJECTIVE: Intestinal dysmotility and immune activation are likely involved in the pathogenesis of small intestinal bacteria overgrowth (SIBO) in irritable bowel syndrome (IBS). We aimed at investigating the role of interstitial cells of Cajal (ICC) and intestinal inflammation in the development of SIBO using a post-infectious IBS (PI-IBS) mouse model. MATERIALS AND METHODS: NIH mice were randomly infected with Trichinella spiralis. Visceral sensitivity and stool pattern were assessed at 8-weeks post-infection (PI)...

Context • Small intestinal bacterial overgrowth (SIBO) is commonly defined as an increased number of bacteria and/or an abnormal type of bacteria in the small intestine. Conventional treatment for SIBO is typically focused on antibiotics to eradicate the bacterial overgrowth. Numerous studies have demonstrated the antimicrobial activity of herbs, and a diet low in fermentable oligo-, di-, and monosaccharides and polyols (FODMAPs) has been shown to enhance antibiotic therapy. Objective • The current case study intended to evaluate the benefits of an alternative, multifaceted approach-including botanical and homeopathic therapies in conjunction with a low-FODMAP diet-in the treatment of SIBO and its associated symptoms...

Intestine barrier disruption and bacterial translocation can contribute to sepsis and multiple organ failure, leading causes of mortality in burn-injured patients. In addition, findings suggest that ethanol (alcohol) intoxication at the time of injury worsens symptoms associated with burn injury. We have previously shown that interleukin-22 (IL-22) protects from intestinal leakiness and prevents overgrowth of gram-negative bacteria following ethanol and burn injury, but how IL-22 mediates these effects has not been established...

Changes in diet, lifestyle, and exposure to environmental risk factors account for the increased incidence of pancreatic disorders, including acute and chronic pancreatitis, and pancreatic cancer. The role of the microbiota in the development of pancreatic disorders is increasingly acknowledged. The translocation of gut bacteria and endotoxins following gut barrier failure is a key event contributing to the severity of acute pancreatitis, while small intestine bacterial overgrowth is common in patients with chronic pancreatitis and further worsens their symptoms and malnutrition...

Gut microbiota is the largest organ of the human body. Although growth of bacteria more than 105 colony forming unit (CFU) per milliliter in culture of upper gut aspirate is used to diagnosis small intestinal bacterial overgrowth (SIBO), 103 CFU or more is being considered to suggest the diagnosis, particularly if colonic type bacteria are present in the upper gut. Although neither very sensitive nor specific, hydrogen breath tests are widely used to diagnose SIBO. Rifaximin is the best treatment for SIBO due to its broad spectrum, lack of systemic absorption, and safety profile...

BACKGROUND: Some theorize that prolonged use of proton pump inhibitors (PPIs) may increase the risk of small intestinal bacterial overgrowth (SIBO). Chronic acid suppression and resultant hypochlorhydria may lead to an altered intraluminal environment, which, in turn, may promote the growth of bacteria in the small intestine. A handful of studies measured the risk of SIBO in adults taking PPIs and obtained mixed results; however, this risk has not been exclusively measured in children...

Hepatic encephalopathy (HE) is a neuropsychiatric disorder that commonly complicates the course of patients with liver disease. Despite the fact that the syndrome was probably first recognized hundreds of years ago, the exact pathogenesis still remains unclear. Minimal hepatic encephalopathy (MHE) is the earliest form of HE and is estimated to affect more that 75% of patients with liver cirrhosis. It is characterized by cognitive impairment predominantly attention, reactiveness and integrative function with very subtle clinical manifestations...

BACKGROUND: Intestinal ischemia/reperfusion injury (I/R) is a significant cause of morbidity and mortality in surgical patients. Ceramide is a mediator of apoptosis and has been implicated as increasing bacterial infection susceptibility. The metabolite of ceramide, sphingosine, was recently shown to play an important role in the cell-autonomous, innate immune response of the upper respiratory tract by killing bacterial pathogens. The role of ceramide and/or sphingosine after mesenteric I/R is unknown...
