Common probiotic no help to young kids with stomach virus

September 16, 2019


Every year millions of children worldwide get an episode of gastroenteritis. Gastroenteritis is caused by one of several germs. It is characterized by vomiting and/or diarrhea. Our gut has a lot of bacteria in it. Probiotics are members of gut bacteria that are believed to be healthy. They are a single bacteria taken out of the gut and grown up in a flask and then washed and put into packages and sold as probiotics. For years people have been giving probiotics to children with gastroenteritis in the hopes that it could shorten their illness or make their symptoms better. Dr. David Schnadower asked a simple question: If children come into our emergency department with gastroenteritis and receive a probiotic or are randomized to receive a placebo, do the children who receive the probiotic get better any quicker. And the answer, after enrolling nearly 1,000 children over several years at multiple sites in the United States, the answer was a resounding no. That the children who received the probiotic got better at the exact same rate as the children who received the placebo. So my recommendation to a family would be that a probiotic in a setting like this is probably harmless, but it is certainly not going to shorten the illness. I would recommend that they not spend their money on it and save that money, the child gets better, and invest it in fresh fruits and vegetables.

    Dear Washington University School of Medicine
    :

    Please consider in your video title the concludings remarks given by the editorial in the last issue of New England journal of medicine:

    …"However, given the large number of probiotic agents now available and considering their various mechanisms of action, abilities to colonize the bowel, and probably narrow potential efficacy for specific diseases, the possibility remains that probiotics other than L. rhamnosus might be effective in infectious diarrhea in children"…
    DOI: 10.1056/NEJMe1814089

    Benefficals effects of probiotics dependes on strain and recent studies published at the same issue (N Engl J Med 2018; 379:2002-2014 and N Engl J Med 2018; 379:2015-2026) analized only two strains (Lactobacillus rhamnosus and L.helveticus). The information provided by your title (probiotics no help) suggest that all strains are usefeul. Besides even the two articles previously cited doesn't tell us anything about effectiveness of the other strains used as probiotics to young kids with stomach virus.

    Kind regards.
