MILE-INDUCED ASTHMAIN CHILDREN. Javesh Kanuua.M.D.,Edaar Yee.M.D , ami L. Bahna.N.D..Dr,P.H.Cleveland,bh~o. The role of food allergy in asthma is controversial and characteristics of such patients are unclear. We studied 32 children, 5 mo-11 yr (mean -34 mo., median 24 mo) with asthma (+/other atowic diseases). Milk allerov was supectkd in all by'history, ski&testing , or RAST to whole cow's milk, caseinj beta-lactoglobulin or alphalactalbumin. Supervisedoralchallenge with conventional cow's milk formula confirmedmilk-induced asthma [MIA) in lo/32 (31%), other atopic symptoms in 6/32 (19%), and negative or equivocal in 16/322(50%). -Age of onset of wheezing in the MIA group tended to be earlier than in the other patients (median 6.5 mo vs 9 mo). Total IaE elevation (>2SD) was mori frequent-in MIA; 00% vs 21% of the food challenae negative group. Positive or& challenge correlatedwithhistoryplus skin testing more than history plus BAST (80% vs 40%). Therefore, MIA is more likely to occur in children with total IgE and young age, elevated positive skin test to bovine milk proteins.

Sweden. 65 infants with family history of atopy and with mothers on a diet free from eggs, cow's milk and fish during the first 3 months of lactation (Dgroup) and 50 matched infants without maternal diet restrictions (ND-group) were followed prospectively 5 times during the first 18 months. The results have been published previously. At four years of age the children examined and skinwere interviewed, prick-tested (SPT) to 4 food- and 3 inhalant allergens. The cummulative and the current incidences of atopic dermatitis were significantly lower in the D-group (19 vs 28 and 6 vs 19, respecThe incidence of respiratory tively). symptoms was similar. The number of children with positive SPT was 7 D children and 11 ND children. We conclude that maternal diet restrictions during lactation seem to have long term effects on atopic dermatitis in children with heredity for atopic diseases. However, further studies are desirable and with larger and randomized groups and longer period of maternal diet.
