[Bronchial provocation test with dermatophagoides in the diagnosis of infantile asthma: sensitivity, specificity and reproducibility].
The purpose of this study has been to prove if the lung is the target organ of an allergen against which a biological hypersensitivity, by means of skin test and RAST, has been found; comparing score Foucard diagnostic with inhalatory test result. At the same time, checking test specificity and reproductibility. Fourty children, both sexes aged between 6 and 14 years diagnosed of bronchial asthma divided in two groups were studied. First group included 31 children with hypersensitivity to dermatophagoides and second group was control group including 9 children. The test with dermatophagoides was performed in both groups according to Cockcroft method. The parameters which indicated test positivity were 20% fall in FEV1 for early response and 40% fall in PERF for late response. The results obtained show 83.9% positive tests with 80.6% early responses and 45.2% positive late response. The specificity and reproductibility were of 100%.
