Abstract: 100 unselected adult asthmatics were prick tested for allergy to housedust mite, Dermatophagoides pteronyssinus. 71% of them were positive compared with only 12% of the controls. Among the 100 patients studied, there were 79 patients with early onset asthma and 21 patients with late onset asthma (after 40 years old). The incidence of positive reaction among the patients with early onset asthma was 79% which was higher than the 43% among the patients with late onset asthma. 54 of the above 100 asthmatics were later prick tested against 21 common allergens. Positive prick test reactions were most commonly seen to housedust mite, D. pteronyssinus (65%), housedust (52%), feathers (35%), human hair (17%), cotton flock (5.5%), shrub pollens (5.5%) and aspergillus fumigatus (5.5%). Serum estimation for specific IgE for house dust mite was performed on 18 patients randomly selected of the 100 patients. This was carried out by the radioallergosorbent test on 10 ml of serum and semiquantitive values estimated. Out of the 18 cases whose blood was measured for specific IgE, 12 had positive skin tests, but 11 of them had detectable values of specific IgE against housedust mite. There is good correlation.
