Dairy consumption and vitamin D concentration in adolescents with challenge-confirmed cow's milk allergy during infancy.

Background/objectives: Milk is an important source of dietary calcium and, if fortified, vitamin D. Cow's milk allergy (CMA) is treated with a milk elimination diet. Although most children become tolerant by age 3 years, some continue dairy avoidance.

Allergic symptoms and sensitisation in adolescents with cows' milk allergy and atopic eczema in infancy.

Background: The association between atopic sensitisation, atopic eczema (AE) and asthma is known, but distinct roles of allergies on long-term health are unestablished.

Objective: Evaluation of allergic symptoms and sensitisation in adolescents who in infancy had AE and verified cows' milk allergy (CMA) or AE and a negative CMA challenge, and controls.

Methods: Children with AE, with and without CMA, from a randomised controlled study in 1999-2001 examining the effect of probiotics on AE severity at older than 12 months of age, attended a follow-up visit at age 16 to 18, with age-matched controls.
