Scientific title	Effect of probiotics (Bifidobacterium bifidum, Bifidobacterium lactis, Lactobacillus acidophilus) in the primary prevention of atopic dermatitis: a double-blind, randomised, placebo-controlled trial
Study hypothesis	To investigate whether prenatal and postnatal administration of a mixture of Bifidobacteria and Lactobacillus can prevent the development of atopic dermatitis (AD) and sensitisation against common food allergens in infants at high risk of atopic disease.
Ethics approval(s)	Ethical Committee at the Samsung Medical Center gave approval on the 14th March 2005 (ref: 2005-03-033)
Condition	Atopic eczema
Intervention	The selected participants were assigned to treatment groups by computerised block-randomisation and received either probiotics or placebo. Mothers in the probiotics group took a mixture of Bifidobacterium bifidum BGN4 (1.6 x 10^9 colony forming units [CFU]), Bifidobacterium lactis AD011 (1.6 x 10^9 CFU) and Lactobacillus acidophilus AD031 (1.6 x 10^9 CFU) in 0.72 g of maltodextrin and 0.8 g of alpha-corn (Bifido Inc., Hongchungun, Korea) once daily from 4 weeks before delivery to 3 months after delivery. Infants were fed the same powder dissolved in breast milk, infant formula, or sterile water from 4 to 6 months of age. Mothers and infants in the placebo group took maltodextrin and alpha-corn without probiotic bacteria. All mothers were requested to breastfeed their infants for at least 3 months after birth. Thereafter, they were permitted to feed their infants with cow's milk formula. Lactating mothers and infants were prevented from eating peanuts and eggs, as well as yogurt and other probiotic functional foods, during the course of the study.

Primary outcome measure	1. Rate of caesarean delivery, collected at 3 months of infant's age 2. Total duration of the breastfeeding, collected at 3, 6, and 12 months of infant's age 3. Infections, collected at 3, 6, and 12 months of infant's age 4. Antibiotic use, collected at 3, 6, and 12 months of infant's age 5. Hospitalisation during infancy, collected at 3, 6, and 12 months of infant's age 6. Prevalence of respiratory infection and acute gastroenteritis, collected at 3, 6, and 12 months of infant's age 7.

Serious adverse events related to the administration of probiotics, collected at 3, 6, and 12 months of infant's age
Secondary outcome measures	1. Effects of probiotics on development of atopic dermatitis, collected at 3, 6, and 12 months of infant's age 2.

Eligibility

Participant type(s)	Patient
Age group	Adult
Sex	Female
Target number of participants	110
Total final enrolment	112
Participant inclusion criteria	Pregnant adult women with a family history of atopic diseases. A positive family history was defined as the presence of at least one first-degree family member having AD, asthma, or allergic rhinitis. The AD of members of the participants' families was confirmed by a physician at enrolment. Those who had been diagnosed as having asthma or allergic rhinitis were selected only when they showed house dust mite-specific immunoglobulin E (IgE) over 1.0 kU/l by cap-system fluorescent enzyme immunoassay (CAP-FEIA) (Pharmacia, Uppsala, Sweden).
Participant exclusion criteria	1. Babies with a congenital disorder 2. Premature babies
