Summary: Hydrogen (H₂) breath tests serve several purposes. (i) detect malabsorption of carbohydrates such as lactose and fructose, (ii) measurement of oro-caecal transit time (iii) associate hydrogen production with the onset of abdominal symptoms like bloating, flatulence, pain, and diarrhea (which indicates carbohydrate intolerance), and (iv) diagnose small intestinal bacterial overgrowth (SIBO). It is ...

Summary: Hepatic encephalopathy (HE), a severe complication of decompensated cirrhosis, is characterized as neurocognitive dysfunction. Emerging evidence suggests the potential role of human albumin infusion for the treatment of HE, but its optimal dosage remains undefined. Therefore, the investigators planned a randomized controlled trial (RCT) to compare the efficacy of human albumin infusion at differen...

Summary: The purpose of this study is to learn more about how to improve treatment of patients with diarrhea predominant Irritable Bowel Syndrome (IBS-D) symptoms.Included patients will be requested to answer online surveys and will undergo treatment with rifaximin. Hydrogen breath testing and biologic samples collection will also be completed during the study.

Summary: Constipation is the most common gastrointestinal manifestation in diabetic patients. Emerging evidence suggests that gut microbiota dysbiosis may contribute to the pathogenesis of diabetes, highlighting the need to investigate its role in diabetic constipation, though current research remains limited. Current management of diabetic constipation primarily relies on bulk-forming and osmotic laxative...

Objectives: * To assess the 1st breakthrough episode of HE during 6months in BCAA vs rifaximin groups as ideal secondary prophylaxis in HE. Methodology * Double-blind placebo-controlled double-dummy randomized trial of BCAA supplementation vs rifaximin as the ideal second-line therapy in patients with cirrhosis who have recovered from an episode of OHE. Expected Outcome * Ideal second line agent HE prophylaxi...

Summary: The purpose of this study is to prospectively analyze the prevalence of SIBO in patients with Pancreatic adenocarcinoma (PDAC) and understand its association with weight loss and pancreatic resection status. Each patient will be tested for SIBO using Lactulose Hydrogen Breath Test. 100 patients with diagnosed pancreatic adenocarcinoma and clinically diagnosed weight loss will be enrolled in this s...

Summary: Constipation is one of the most prevalent gastrointestinal disorders in patients with chronic kidney disease (CKD) and has been associated with their adverse kidney and cardiovascular outcomes; however, little is known about the effects of constipation treatment on clinical outcomes nor on outcome-related biochemical and microbiological parameters in patients with CKD. The investigators aim to tes...

Summary: The goal of this study is to test the effect of a probiotic formulation on gastrointestinal symptoms, gut and small intestine microbiota in participants suffering from small intestinal bacterial overgrowth (SIBO). Two doses of probiotic will be evaluated against placebo.

Summary: To investigate in a prospective way changes in Mucosal-Associated Invariant T (MAIT) cells frequency, phenotype and function in link with the gut microbiota, gut integrity and the presence of Coxsackie virus B in two cohorts of pediatric patients: patients with a high genetic risk of type 1 diabetes and pediatric patients with recently diagnosed T1D by comparison with control subjects Tasks: 1. To...

Summary: This study aims to compare the efficacy and safety of the combination drug Clotrimazole+Lactulose with the monocomponent product Canesten® (clotrimazole) in adult women diagnosed with candidal vulvovaginitis. The primary objective was to confirm the superiority of the combination drug in terms of clinical and microbiological response on Day 25 of the study.

Summary: Constipation (constipation) is a common clinical symptom, including difficulty in defecation and / or reduced frequency of defecation, dry and hard stool, difficulty in defecation, feeling of inexhaustible defecation, feeling of anorectal obstruction, time-consuming defecation and need for auxiliary defecation. Reduced defecation means defecation less than 3 times a week.Constipation is very commo...

Summary: Rationale: Hepatic encephalopathy (HE) is a major and common complication in patients with liver cirrhosis. HE can be classified in the extensive range of neurocognitive deterioration as minimal HE (MHE), covert HE (grade I), or overt HE (OHE, grade II-IV). Liver cirrhosis is the most common cause of portal hypertension (PH). Patients who develop complications of PH, like variceal bleeding or refr...
