Results In such period, 100 new patients were seen, mainly comprised of male (64%). Most patients (69%) were under 6 months old at the time of their first visit. In 41% of the patients, the first contact with cow’s milk protein occurred before 1 month old and only 21% had such contact after 6 months of age. One (1%) patient had symptoms with no direct exposure to cow’s milk (allergy linked to breast milk). Respiratory symptoms, whether alone or associated with other complaints, were the most frequent ones in 81% of the cases (rhinitis 32%), followed by dermatitis in 44% and vomiting in 20%. Patients assessed at first visit were on cow’s milk (LV) in 30%, soy milk 30%, breast milk (LM) 9%, partially hydrolyzed (PH) 11%, extensively hydrolyzed (EH) 9.5%, free amino acids (AA) 9.5% and 1 patient on calcium replacement. Following first evaluation, they were switched to: soy 35%, EH 30%, PH 22%, LV 6.5%, AA 6.5%, and LM 1%. At the time of first visit, 23.5% of patients on cow’s milk protein haven’t started treatment yet or were partially treated, thus requiring switch to another formula. Soy was properly indicated in 30% of patients, with no need for changing formula. In service experience, PH formula showed good results in patients whose relatives were atopic and/or oligosymptomatic. EH formulas were the most indicated ones (30%) at this first evaluation; therefore decreasing AA prescriptions (5.5%) which were below the numbers described in literature.
