Oral application of bacterial lysate in infancy diminishes the prevalence of atopic dermatitis in children at risk for atopy
Numerous interventions such as avoidance of food allergens, prolonged breast feeding and supplementation of pro-and/or prebiotics have been tried as primary prevention of atopic dermatitis. Recent data suggest that prevention of infantile eczema is possible in a subgroup of children by feeding bacterial lysates early in life. Bacterial lysates of Escherichia coli and Enterococcus faecalis were found to impair allergic immune responses in rats. An interventional trial in 606 infants at risk for atopy showed a reduction of atopic dermatitis at the end of the treatment phase (month 2 until month 7) of 50% in a subgroup of children with single heredity for atopy. This was even more pronounced in the group of children with paternal heredity for atopy. This effect was still seen at age 1 year. There was no effect on food sensitisation. In conclusion, an immune modulation in terms of prevention of atopic dermatitis in infancy if single atopic family history is present seems to be possible by feeding bacterial lysates early in life.

More about this publication?
- Beneficial Microbes is a peer-reviewed scientific journal with a specific area of focus: the promotion of the science of microbes beneficial to the health and wellbeing of man and animal. The journal contains original research papers and critical reviews in all areas dealing with beneficial microbes in both the small and large intestine, together with opinions, a calendar of forthcoming beneficial microbes-related events and book reviews. The journal takes a multidisciplinary approach and focuses on a broad spectrum of issues, including safety aspects of pro- & prebiotics, regulatory aspects, mechanisms of action, health benefits for the host, optimal production processes, screening methods, (meta)genomics, proteomics and metabolomics, host and bacterial physiology, application, and role in health and disease in man and animal. Beneficial Microbes is intended to serve the needs of researchers and professionals from the scientific community and industry, as well as those of policy makers and regulators.
