title: Antibiotics during childhood and inflammatory bowel disease?
abstract: Four epidemiological studies, including two large cohort studies in children aged 17 years or under, have studied the link between antibiotic therapy and inflammatory bowel disease. The risk of inflammatory bowel disease appeared to be twice as high in children exposed to an antibiotic as in unexposed children. The risk appeared higher following exposure during the first year of life, with beta-lactam antibiotics, and with repeated antibiotic courses. One postulated mechanism is through destruction of the anaerobic intestinal flora by antibiotics. In practice, these data provide yet another reason to avoid unnecessarily exposing children to antibiotics.
