ABSTRACT
Objective@#To evaluate the efficacy and safety of Saccharomyces boulardii in the prevention of antibiotic-associated diarrhea (AAD) in infants and young children.@*Method@#From November 2012 to September 2013, ten research units of large teaching hospitals or children′s hospitals participated in this multicenter randomized controlled clinical trial. Hospitalized young children aged between 1 month and 3 years (nongastrointestinal infection and antibiotic therapy required)were involved in our study. The children were randomly divided into control group and prevention group by means of block random allocation method. The control group received antibiotic therapy and other conventional treatment. The prevention group was given additional Saccharomyces boulardii (250 mg/d) orally. Diarrhea rates of two groups were compared both during the usage of antibiotics and within 14 days after the antibiotics withdrawal. The adverse reactions of Saccharomyces boulardii were observed all through this study. The results were analyzed by χ2 test or Kruskal-Wallis test or t test.@*Result@#Totally 408 cases (213 cases in prevention group and 195 cases in control group) were enrolled. The age ranged from 1 month to 3 years, with an average age of 1.14 years. The basic diseases were parenteral infections: 368 cases with different kinds of respiratory tract infections or pneumonia, 10 cases of bacterial meningitis, 9 cases with septicemia or sepsis, 6 cases with pertussis or pertussis like syndrome, 5 cases with urinary infection, 5 cases with skin or subcutaneous tissue infections, 3 cases of Kawasaki disease, one with scarlet fever and one with congenital syphilis. During the administration of antibiotics, the incidence of AAD in prevention group was 10.3% (22 cases), which was significantly lower than that of control group (57 cases, 29.2%, χ2=23.296, P<0.05). Within 14 days after the discontinuation of antibiotics, the percent of new diarrhea cases in prevention group (2.4%, 5/213) was also significantly lower than that in control group (16.4%, 32/195, χ2=23.4, P<0.05). Further analysis revealed that the rate of AAD in children less than or equal to 1 year old (25.1%, 52/207) was significantly higher than that of over 1 year old (13.4%, 27/201, χ2=8.922, P<0.05). The incidence of AAD in children treated with antibiotics for more than 5 days was 22.2%(60/270), which was significantly higher than that of less than or equal to 5 days (13.8%, 19/138, χ2=4.180, P<0.05). Although no significant difference was observed, the AAD rate of patients with combined use of two antibiotics was higher than that of using one. During the antibiotic therapy, compared with the control group, the risk of AAD in children under 1 year old was reduced by 52% (χ2=9.217, P<0.05), and 91% (χ2=20.35, P<0.05) in the children over 1 year old in prevention group. The risk of AAD of prevention group decreased by 66% (χ2=13.67, P<0.05) in patients treated with one antibiotics, and 65% in children with combined use of antibiotics (χ2=10.57, P<0.05). In patients treated with antibiotics for less than or equal to 5 days, the risk of AAD decreased by 74% in prevention group (χ2=7.38, P<0.05); and 63% if the course lasted for over 5 days (χ2=16.87, P<0.05). Within 14 days after the withdrawal of antibiotics, compared with the control group, the risk of diarrhea in the prevention group decreased by 82% (χ2=13.35, P<0.05) in infants (≤1 year old) and 93% (χ2=12.00, P<0.05) in children (>1 year old); the risk of diarrhea was reduced by 86% (χ2=9.57, P<0.05) and 87% (χ2=17.71, P<0.05) respectively in prevention group with single and combined use of antibiotics. In patients treated with antibiotics for more than 5 days, the risk of diarrhea in prevention group was reduced by 63% (χ2=22.79, P<0.05), while there was no significant difference if the antibiotics course was less than or equal to 5 days (χ2=2.97, P>0.05). No adverse effects related with Saccharomyces boulardii were observed in our study.@*Conclusion@#Saccharomyces boulardii is effective and safe to prevent AAD of infants and young children both during the usage of antibiotics and up to 14 days after drug discontinuance. It can be one of the drugs of for choice prevention of AAD in infants and young children. Trial registration Chinese Clinical Trial Tegister, ChiECRCT-2012-25.
