BACKGROUND Helicobacter pylori (H. pylori) is one of the most common bacterial infections in humans. There is a risk factor for gastric or duodenal ulcers, gastric cancer and MALT (Mucosa Associated Lymphoid Tissue)-Lymphomas. There are several invasive and non-invasive methods available for the diagnosis of H. pylori. The (13)C-urea breath test is a non-invasive method recommended for monitori...

BACKGROUND Small intestinal bacterial overgrowth and sugar malabsorption (lactose, fructose, sorbitol) may play a role in irritable bowel syndrome. The lactulose breath test is a reliable and non-invasive test for the diagnosis of small intestinal bacterial overgrowth. The lactose, fructose and sorbitol hydrogen breath tests are widely used to detect specific sugar malabsorption. AIM To asses...

BACKGROUND Oro-cecal transit time (OCTT) is determined for clinical diagnostics of intestinal complaints and research purposes. Ingestion of a subsequent meal during the test period shortens the OCTT of a liquid test meal (glucose solution), as previously reported. This study was conducted to determine whether the same phenomenon occurs after ingestion of a solid test meal. MATERIALS AND METH...

OBJECTIVE to test whether omeprazole taken for longer than 1 month causes an increase in the rate of small bowel bacterial overgrowth in elderly subjects. SUBJECTS 44 elderly people, 22 taking omeprazole, 22 not taking omeprazole or H2 receptor antagonists. MAIN OUTCOME MEASURES rate of positive glucose-hydrogen breath tests; anthropometric measures and blood tests reflecting malabsorption....

BACKGROUND/AIMS Patients undergoing cholecystectomy may have small intestinal bacterial overgrowth (SIBO). We investigated the prevalence and characteristics of SIBO in patients with intestinal symptoms following cholecystectomy. METHODS Sixty-two patients following cholecystectomy, 145 with functional gastrointestinal diseases (FGIDs), and 30 healthy controls undergoing hydrogen (H2)-methane...

Background/Aims Gastroesophageal reflux disease (GERD) is a frequent condition diagnosed in children and treated with proton pump inhibitors (PPI). Long-term PPI administration can alter intestinal bacterial population by suppressing the gastric acid barrier and may cause diarrhea. The aim of this study is to evaluate the prevalence of small intestinal bacterial overgrowth assessed by glucose h...

BACKGROUND Helicobacter pylori is implicated as the causative agent for most duodenal and gastric ulcers. Invasive (endoscopy and biopsy) and noninvasive (serology, breath test) methods are currently available for definitive diagnosis of infectious peptic ulcer disease. METHODS Twenty-six patients with chronic gastritis symptoms underwent upper endoscopy, biopsy, rapid urease test, and [14C]u...

BACKGROUND An association between irritable bowel syndrome (IBS) and small intestinal bacterial overgrowth (SIBO) has been found. OBJECTIVE To compare the prevalence and test results for bacterial overgrowth between IBS and fibromyalgia. METHODS Subjects with independent fibromyalgia and IBS were compared with controls in a double blind study. Participants completed a questionnaire, and a l...
