Synopsis: The preventive effect of CBM was investigated for antibiotic-associated diarrhea (AAD) in children. One hundred and ten children who suffered from upper respiratory tract infection or gastroenteritis were divided into three groups. Twenty-seven of the patients received only antibiotics, 38 received CBM from the mid-point of the antibiotic treatment and 45 concomitantly received CBM from the beginning of the antibiotic treatment. To examine the effects of CBM on AAD, the changes in intestinal microbiota were investigated. Diarrhea was observed in 59% of the subjects who received only antibiotics, and total fecal anaerobes, especially Bifidobacterium, were remarkably decreased. In contrast, diarrhea in subjects who received CBM from either the middle or the beginning of the antibiotic therapy was decreased to 5% and 9%, respectively. Concomitant administration of CBM increased anaerobes and prevented the decrease of Bifidobacterium in the subjects who received antibiotics. Clostridium butyricum MIYAIRI is effective for both the treatment and the prophylaxis of AAD in children, as it normalizes the intestinal microbiota disturbed by antibiotics.
