Successful treatment of rotavirus diarrhea in children with immunoglobulin from immunized bovine colostrum

BACKGROUND: Oral ingestion of immunoglobulins in humans has been shown to be effective as prophylaxis against enteric infections. However, its therapeutic effect in children with infectious diarrhea has hitherto not been proven. We treated children with rotavirus diarrhea with immunoglobulins extracted from immunized bovine colostrum (IIBC) containing high titers of antibodies against four rotavirus serotypes. METHODS: In this double blind placebo-controlled trial, 80 children with rotavirus diarrhea were randomly assigned to receive orally either 10 g of IIBC (containing 3.6 g of antirotavirus antibodies) daily for 4 days or the same amount of a placebo preparation. The daily stool output (grams/kg/day), intake of oral rehydration solution (ml/kg/day), stool frequency (number of stools/day) and presence of rotavirus in stool were monitored…
