[Statistical study of 428 Piedmont residents suffering from bronchial asthma of allergic etiology].
This 6-year (1979-1984) study was conducted on subjects with allergic bronchial asthma diagnosed by scarification skin tests. The skin tests identified 428 subjects with bronchial asthmatic symptoms including 228 females and 220 males (females/males = 1.04). In the 6-15 age range there was a clear predominance of males over females (42 against 24 or males/females = 1.75). At the time of testing, 309 subjects (72.2%) were in the 6-35 age range. In terms of symptoms, 61 subjects (14.2%) presented bronchial asthma alone. The most common combination of symptoms encountered was asthma-rhinitis-conjunctivitis found in 317 subjects (74.1%). Symptoms were seasonal in 305 patients (71.3%) while 123 (28.7%) presented asthmatic symptoms throughout the year. 382 patients (89.25%) presented pollen allergy with grass pollen accounting for the highest percentage (328 subjects or 76.6%). 46 subjects (10.7%) were allergic to tree pollen and 103 (24.1%) to flower pollen. 197 patients (46%) were allergic to permanent inhalants (domestic inhalants, epithelia, mycophytes) with Dermatophagoides Farineae accounting for the largest number (33.4%). 55 subjects (12.9%) were sensitive to at least one of the epithelia tested while mycophyte sensitivity was negligible (10 subjects or 2.3%).
