Abstract
Lactulose has been shown to modify the gut microbiota in increasing bifidobacteria and reducing the numbers of clostridia. In this pilot study we investigated whether the microbiota could be modified in infants with atopic manifestations with or without gastrointestinal symptoms. We could safely promote the bifidobacterial microbiota in symptomatic infants by feeding a low dose of lactulose. The symptoms of the children were concomitantly improved.
