A total of 300 asthmatic patients (children from 6 months to 13 years), who were attending paediatrics respiratory clinic at Ibn Sina Teaching Hospital and Out-Patient Clinic in Central Polyclinic, Sirt-Libya, were tested for their responses to skin prick test using purified house dust mites (HDM) allergens. Out of the 300 patients suffering from bronchial asthma, 204 (68%) showed variable allergic response to various HDM purified allergens. 57% of the positive cases showed positive response to Dermatophagoide pteronyssinus ( Der pter) antigens, and 28% of cases to Dermatophagoide farinae (Der far) antigens and 14% showed positive response to Lepidoglyphus destructor (L.d) antigens. Of the 204 patients with positive reaction, 64.2% gave severe reaction while 21% gave moderate and 14.8% gave mild reactions. Theses reactions were more severe in males than females.
