Celiac Disease by the Age of 13 Years Is Not Associated With Probiotics Administration in Infancy.

Probiotics are theoretically promising in primary prevention of celiac disease (CD), but research evidence on the topic is scarce. We used the data and material of a clinical double-blind randomized placebo-controlled trial on primary allergy prevention (n = 1223) to investigate in an exploratory study whether administration of a mix of pro- and prebiotics during late pregnancy and first 6 months of life was associated with prevalence of CD during 13-year follow-up. Children who fulfilled diagnostic criteria for CD (n = 11) and subjects with a serum sample available for analyzing CD antibodies (n = 867) were included.

Serum 25-Hydroxyvitamin D in Early Childhood Is Nonlinearly Associated with Allergy.

Background: Vitamin D has several immunological functions. Data on the relation of vitamin D status and allergy are controversial.

Methods: We investigated the association between serum concentrations of 25-hydroxyvitamin D (25-OHD) and allergy in childhood.

Specific antibodies to cow's milk proteins in infants: effect of early feeding and diagnosis of cow's milk allergy.

Purpose: To investigate whether specific IgA, IgG, IgG1 and IgG4 responses to cow's milk proteins differ between infants with cow's milk allergy and infants with cow's milk related symptoms (control subjects), and whether early feeding affects these responses as well as specific IgE.

Methods: A cohort of 6,209 healthy, full-term infants in a double-blind randomized trial received, as supplementary feeding at maternity hospitals (mean duration 4 days), either cow's milk formula, extensively hydrolyzed whey formula or donor breast milk. Infants who developed cow's milk associated symptoms (n = 223) underwent an open oral cow's milk challenge (mean age 7 months), which confirmed cow's milk allergy in 111 and was negative in 112.
