Oral bacterial therapy reduces the duration of symptoms and of viral excretion in children with mild diarrhea.
BACKGROUND Oral administration of live Lactobacillus casei strain GG is associated with the reduction of duration of diarrhea in children admitted to the hospital because of diarrhea . The purpose s of this work were to investigate the clinical efficacy of oral administration of Lactobacillus in children with mild diarrhea who were observed as out patients , and to see whether Lactobacillus GG can reduce the duration of rotavirus excretion . METHODS Duration of diarrhea was recorded in 100 children seen by family pediatricians and r and omly assigned to receive oral rehydration or oral rehydration followed by the administration of lyophilized Lactobacillus casei , strain GG .  Rotavirus was looked for in the stools of all children and in those in whom results were positive , stools were examined again 6 days after the onset of diarrhea . RESULTS In 61 children results were positive for rotavirus and in 39 results were negative . Duration of diarrhea was reduced from 6 to 3 days in children receiving Lactobacillus GG , with a similar pattern in rotavirus-positive and -negative children . Six days after the onset of diarrhea , stools in only 4 out of 31 children that received Lactobacillus GG were positive for rotavirus compared with positive findings in 25 out of 30 control subjects . CONCLUSIONS Oral administration of Lactobacillus GG is effective in rotavirus-positive and rotavirus-negative ambulatory children with diarrhea . Furthermore , it reduces the duration of rotavirus excretion
