Filter by:The goal of this clinical trial is to test the effectiveness of probiotic bacterial supplements as an additional therapeutic modality in patients with small intestine bacterial overgrowth who receive oral antibiotic treatment (rifaximin) The main questions it aims to answer are: 1 To evaluate the effectiveness of a dietary intervention using pro-biotic bacterial strains as an adjunct to treatment of SIBO with rifaximin. 2. Evaluation of ultrasonographic imaging of mesenteric lymph nodes in patients with SIBO. 3. Evaluation of the effect of rifaximin treatment and dietary intervention on non-alcoholic fatty liver disease activity parameters in patients with coexisting NAFLD and SIBO. According to the study schedule, a total of 3 visits will be made within 3 months. Visit 1, after 6 weeks Visit 2 and after another 6 weeks, Visit 3. Patients will also be invited to a follow-up Visit 4, three months after completing participation in the study. All study participants will receive treatment recommendations for SIBO in accordance with standard practice - a 14-day antibiotic treatment with Rifaximin. In addition, a randomly selected half of the study participants will receive probiotic therapy and half a placebo. - An ultrasound examination of the mesenteric root lymph nodes will be performed at each visit, - followed by a lier steatosis/fibrosis assessment using SWE elastography or FibroScan. - Blood sampling is required on each visit. All study participants will receive detailed guidelines during dietary consultations at each visit for the use of a low FODMAP diet. - Each participant will receive a paper diary on how to assess the severity of bloating and evaluate bowel movements, which must be filled out daily. - In addition, at the visits the patient will be asked to fill out an additional questionnaire on other gastrointestinal complaints and mental health.
The small intestine is an understudied frontier of microbiome research. While aspiration during endoscopy is considered the gold standard to assess small bowel bacteria, the tools for sterile retrieval are primitive and poorly validated. Endoscopic aspiration is time-consuming and prone to contamination. Inspired by plants' ability to draw water by capillary action, a novel multi-capillary sterile system was designed which is a modified version of the conventional aspiration catheter. The purpose of this study is to examine the time and volume capabilities of this catheter in suctioning various liquids compared to conventional aspiration catheter, in two groups, each includes 23 patients that going under endoscopy at GI lab at Cedars Sinai Medical Center. The investigator will collect up to 2 ml fluid from Duodenum- in first group by using the conventional catheter and in second group by using the capillary catheter. The time collection and the volume of samples in 2 groups will be compared.
