Comparative assessment of <i>Bifidobacterium bifidum, Bifidobacterium longum, Bifidobacterium infantis, Lactobacillus rhamnosus</i> and <i>Saccharomyces boulardii</i> efficacy at diarrheal variant of irritable bowel syndrome

Abstract

Aim of investigation. To estimate effect of probiotics on severity of clinical symptoms, presence of bacterial overgrowth syndrome (BOS) and quality of life at diarrheal variant of irritable bowel syndrome (IBS-D).Material and methods. In 47 patients with diagnosis of IBS-D, confirmed by conformity of symptoms to Rome-III criteria and absence of organic diseases according to carried out investigation comparative analysis of effect of probiotics and placebo on development of main clinical symptoms, state of intestinal microflora and quality of life was applied. Efficacy of probiotics containing microorganisms Bifidobacterium bifidum, Bifidobacterium longum, Bifidobacterium infantis, Lactobacillus rhamnosus (Florasan-D); yeast Saccharomyces boulardii (Enterol) was studied. Overall 25 men (53,2 %) and 22 women (46,8 %) with mean age 33 year (31,5; 37,8) were investigated. Probiotics Florasan-D, Enterol and placebo were prescribed in a doze of 250 mg bid. Intensity of abdominal pain and meteorism was estimated by visual analog scale (VAS), consistency of stool – by Bristol stool form scale, defecation rate — by calculation of number of bowel movements during every week of treatment. Besides that presence of BOS was investigated by hydrogen breath test with lactulose, quality of a life was determined using The Short Form-36 (SF-36) questionnaire prior to treatment onset and its termination. Treatment lasted for 28 days.Results. In group of the patients who received Florasan-D and Enterol, in contrast to as placebo group improvement in relation to severity of main clinical symptoms was marked, quality of a life score increased. Besides that, according to hydrogen breath test with lactulose results on a background of Florasan-D it was possible to eliminate BOS in all patients.
