Brief Summary

Functional dyspepsia (FD) is a common condition associated with significant morbidity, healthcare expenditure, work absenteeism and productivity, and reduced quality of life. The prevalence of this condition is as high as 15% in the rural (Jaunpur district, Uttar Pradesh) and 30% of the urban (Mumbai) Indian population. Pathophysiologically, FD is an enigmatic condition that may be contributed by a variable combination of psychosocial issues like anxiety, depression, insomnia, and micro-organic issues like Helicobacter pylori infection, gastritis, duodenitis, hypersecretion of acid, degree of gastric atrophy, gastric microbiota dysbiosis. Accordingly, investigators want to study these factors among patients with FD. Rifaximin has been shown to be useful in the treatment of FD in a recent randomized controlled trial from Hong Kong. Since microbiota dysbiosis may be an important issue in FD, investigators want to treat them with rifaximin in a randomized placebo-controlled trial and repeat the parameters such as dyspepsia score, hospital Anxiety and Depression Scale (HADS) score, Pittsburgh Sleep Quality Index (PSQI). Investigators wish to study the pathogenetic mechanism of FD and evaluate baseline factors that may help to predict response to gut microbiota manipulation in these patients. Objectives: a. To study the patients with FD for gut microbiota including gastric H. pylori, gastric atrophy (by PG-1 PG-II ratio), hospital anxiety and depression score, and sleep disorders b. To see the effect of treatment of these patients with rifaximin vs. placebo in a randomized controlled trial not only for the improvement in symptoms but also for improvement in HADS score and sleep quality c. To study whether any pre-treatment factors including gut microbiota predict the response of symptoms to treatment with rifaximin.

Outcome Measures

Primary Outcomes (2)

  • Change in composition of gut microbiota

    To study changes from baseline in composition of gut microbiota including gastric H. pylori, gastric atrophy (PG-I, PG-II ratio

    Baseline upto 6 months

  • Hospital anxiety and depression score

    Number of items in the questionnaire reflects anxiety and depression. Each item had been answered by the patient on a four point (0-3) response category and the possible scores ranged from 0-21 for depression (0-7 score indicates normal range, 8-10 indicates 'borderline abnormal or borderline case' and a score of 11 or higher indicates 'abnormal case'.

    Baseline upto 6 months

Secondary Outcomes (1)

  • Sleep quality index score

    Baseline upto 6 months

Study Arms (2)

Rifaximin

ACTIVE COMPARATOR

Rifaximin 550mg thrice daily for 14 days Other Name: Normix

Drug: Rifaximin

Placebo

PLACEBO COMPARATOR

Placebo thrice daily for 14 days

Drug: Placebo

Interventions

Rifaximin has been demonstrated in multiple IBS studies, through a postulated effect on the gut microbiota, to improve the symptoms of pain and bloating, which are important symptoms in subjects with functional dyspepsia

Also known as: Normix
