Abstract:
House dust mites (HDM) contain a large number of components that react with IgE in individuals with allergies and induced sensi-tization and allergic diseases. The work aimed to correlate between clinical manifestations of HDM allergic patients and skin prick test (SPT) grading, and to clarify some markers denoting allergic disorders caused by HDM exposure. Thirty allergic patients with positive SPT reaction to HDM were selected, grading of disease severity according to SPT and clinical presentations. The results revealed bronchial asthma (40%), atopic dermatitis (26.7%), rhinitis (20%) and conjuncttivitis (13.3%). Serum ELISA-IgE showed mean level of 398.41 +/- 84.73, 369.87 +/- 86.76, 332.16 +/- 65.57 and 300.25 +/- 79.39 IU/ml respecttively, with highly statistically significant difference between cases and controls (p < 0.001). Eosinophila showed highly significant difference between atopic dermatitis cases and controls (p < or = 0.001).
