Randomized Controlled Trial
Bifidobacterium animalis subsp. lactis fails to prevent common infections in hospitalized children: a randomized, double-blind, placebo-controlled study.
The incidence of nosocomial infections in children in developed countries is still high, ranging from 8% to 30%, and standard preventive measures, such as increased hygiene, are not sufficiently efficacious. One of the potential strategies for their prevention is the use of probiotics. ⋯ The results of this study show that the use of B. animalis subsp. lactis failed to prevent nosocomial infections in an acute-setting pediatric hospital in children who were >1 y of age. However, it should be taken into account that the overall incidence of nosocomial infections was lower than expected. This trial was registered at clinicaltrials.gov as NCT01702766.
