We analyzed randomly a study of 36 cases among the medical records of patients from the files of the BSFA (Brazilian Society of Food Allergy ), aged between 2 and 16 years, of both genders, with the diagnosis of food allergy and asthma. Asthma was diagnosed by the classical clinical picture. Food allergy was diagnosed by the normalization of the clinical picture in response to the withdraw of the offending food from the patient diet, resulting in total disapearance of the clinical disturbance. All patient relapse after the food chalenge with the offending food. All the patients had both diseases mediated by IgE.
According to age, 25 (69%) of patients were children and 11(31%) were adolecents.The first symptoms began is 4 months in 7 (19.4%) of the patients, for both diseases food allergy and asthma.
With respect to family history of food allergy was observed only in 1st degree relatives, 26 among the mothers (72%), 24 among the fathers (66%) and 7 in brothers (19,4%).
Regarding the gestational history there has been a significant number of patients delivered by cesarean section 31 (86.1%). Only 3 (8.35%) were normal delivery.
