[Behavior of bronchial reactivity in 50 children before and after exclusion of food allergens].

In this study the author has purposed to demonstrated that the food allergens increase the bronchoreactivity. This studied group was formed by 50 boys with chronic rhinitis and/or nasal perennial and/or laryngeal and bronchial obstruction, unresponsive to aeroallergens but responsive to food allergens determined with FBST test. This test is performed by making the patient go on an anallergic diet (formed by tapioca's flour, rabbit, olive oil, beets, lettuce, pear, sugar, salt for seven days). The first week are controlled the spirometric values and every week is introduced a new food with ambulatory control of spirometric values and of Raw and control of domiciliary PEF. The "trapped" reaction is "retard" with fall of all spirometric values at food allergens introduction. Then 15 boys undergone test of free running for six minutes, 15 the aspecific metacholine test and 10 both proofs. Then the 40 boys executed the food allergens exclusion from diet for a three months period; a control group of 10 boys executed the free running and the metacholine ABS and then the diagnosis of food allergens but kept a free diet. After three months the boys repeated the proofs. The group of 40 boys who executed the food allergens exclusion showed and heavy diminution of bronchoreactivity either with free running test either with metacholine ABS test.
