CHANGING PATTERN OF COW'S MILK INTOLERANCE: An Analysis of the Occurrence and Clinical Course in the 60s and mid-70s

ABSTRACT. Verkasalo, M., Kuitunen, P., Savilahti, E. and Tiilikainen, A. (Children's Hospital, University of Helsinki, Finland). Changing pattern of cow's milk intolerance. Acta Paediatr Scand, 70: 289, 1981.–The rapid changeover to commercial adapted infant formulae which took place in Finland between 1973 and 1975 was studied as a factor in the occurrence of severe intestinal cow's milk intolerance (CMI). Of infants treated for CMI in 1962-73, ninety-three percent (25/27) were on homemade or unadapted formulae. The admission rate for CMI in these years was 0.22/1 000 liveborn infants breast fed less than six months. During 1974-77 the corresponding figure was 0.56, with 85 % of the patients (18/26) on adapted cow's milk formulae. The patients treated before 1974 had a longer symptomatic period before admission, greater growth retardation and more severe intestinal damage than those seen during and after 1974. This is believed to reflect mainly the increasing awareness of CMI on the part of both laymen and the medical profession. In the history of 2/3 of the patients at least one of the following conditions was noted: non-breast feeding, infectious gastroenteritis, praematurity, 21-trisomy, prior intra-abdominal surgery, Hirschsprung's disease, and atopic disease in family members. The long follow-up averaging over four years revealed four patients with coeliac disease. In one of these the proximal jejunal mucosa was normal after two years on gluten-containing diet, but he showed a mucosal relapse as late as between 2 to 4 years on normal diet.
