R. Oosaki et al., CLINICAL-FEATURES OF ADULT-RELAPSE ASTHMA IN COMPARISON WITH THOSE OFCHILD-ONSET ASTHMA AND ADULT-ONSET ASTHMA, The Journal of asthma, 31(5), 1994, pp. 339-345
Clinical features of adult-relapse asthma (group B, n = 15) were compa
red with those of child-onset asthma (group A, n = 18) and adult-onset
asthma (group C, n = 34) in terms of allergic component and bronchial
hypersensitivity. The percentage of patients with high levels of seru
m IgE (>300 U/ml) in groups A, B, and C was 83%, 73%, and 50%, respect
ively, and the percentage of patients with positive IgE RAST for house
dust was 87.5%, 78.6%, and 46.7%; and that for mite was 93.3%, 92.9%,
and 58.6% in groups A, B, and C, respectively. The histamine concentr
ation of PC20 for the bronchial hypersensitivity test in groups A, B,
and C was 196 mu g/ml, 500 mu g/ml, and 724 mu g/ml, respectively. Thu
s, the adult-relapse asthma was closer to the child-onset asthma type
in allergic state and closer to the adult-onset asthma type in bronchi
al hypersensitivity state. The classification employed here seemed to
provide some merits in delineating the features of adulthood asthma.
