Oral supplementation with the probiotic Lactobacillus reuteri to the
mother during pregnancy and to the infant after birth may help reduce
the development of eczema and allergy associated with immunoglobulin
E, a key protein involved in the allergic response, according to
Swedish researchers.

Probiotics are small molecules that help maintain the natural balance
of organisms, also referred to as microflora, in the intestines.

Altered microbial exposure may underlie the increase of allergic
diseases in affluent societies. Probiotics may help, Dr. Thomas R.
Abrahamsson of Linkoping University Hospital and colleagues note.

To investigate, the researchers enrolled families with a history of
allergic disease. Expectant mothers were randomly assigned to receive
L reuteri in an oil suspension or a placebo treatment, each day from
week 36 until delivery.

Their babies continued with the same formulation from birth until 12
months of age and were followed up for another year. A total of 188
completed the study.

At 2 years, the incidence of eczema was 36 percent in the active
treatment group and 34 percent in the placebo group. However, during
the second year, only 8 percent of the L. reuteri group had IgE-
associated eczema compared with 20 percent of the placebo group, a
statistically significant difference.

Skin prick test reactivity was also less common in active treatment
group than in the placebo group. The difference was statistically
significant in infants with mothers with allergies (14 percent versus
31 percent). However, there was no effect on wheeze or other
potentially allergic diseases.

Although the study failed to confirm an overall preventative effect on
infant eczema, the investigators conclude that "the treated infants
had less IgE-associated eczema at 2 years of age and therefore
possibly run a reduced risk to develop later respiratory allergic
disease."
