Study summary

Acute diarrhea (AD) is one of the commonest illnesses in children. A particularly severe form of diarrhea is bloody diarrhea (BD).

Saccharomyces boulardii CNCM I-745 is a probiotic with demonstrated efficacy in children with acute diarrhea; however, evidence regarding its use in bloody diarrhea (BD) is lacking. This project aims to assess the efficacy and safety of Saccharomyces boulardii CNCM I-745 on bloody diarrhea in children.

The study objective are :

  • To assess the efficacy of Sacharomyces Boulardi (SB) on acute bloody diarrhea in children aged 0 - 5 years. Indicators: duration of bloody diarrhea, daily frequency of stools with blood, daily frequency of total stools with or without blood during follow up.
  • To assess the most frequent bacterial agents
  • To assess the safety of the product. The study is a double blind, controlled trial (SB or placebo), with two arms parallel, randomized design, carried out on outpatient clinic because of acute bloody diarrhea.
Read the detailed description

Patients with acute bloody diarrhea were prescribed randomly and blindly placebo or Saccharomyces boulardii 500 mg /day seven days (250 mg for children between 0.25 - 1.00 years),and were seen in outpatient clinics of three hospitals at days 1, 3, and 7. On day 14 they were contacted by telephone call. Parents registered daily number of stools, with or without diarrhea, and any new symptom appearing during follow up.
