Abstract

Urticaria can result from many different stimuli and numerous factors; both immunologic and nonimmunologic; are involved in its pathogenesis. But in a large portion of patients with urticaria; at present; the definite etiology have not been found. This study was designed to evaluate the distribution of causative allergens and the common positely reacted allergens in urticaria. The results of allergy skin test with 100 common allergens done in 176 patients with urticaria were analized. The following results were obtained 1. Among the 176 patients; the male to female ratio was 1: 1.2; and the peak incidence was in the 20S and 30S. 2. Of those examined; 56.8% of the 176 patients showed positive reactions to the prick tesk with the peak incidence in the 20S and 30S. 3. Multiple sensitivity was noted in a 89% of cases and the most frequent combination was 2 to 5 allergens. 4. Dust and mites were the most common allergens with positive in 59% of 100 patients; followed by animal danders; pollens; moulds with positivities of 49%; 33% and 25% of the patients respectively. 5. House dust and Dermatophagoides were major allergens among the dust and mites; while cat fur and mixed feathers were most common among the animal dander. Dandelion; maize and nettle pollens were the leading pollens on positivity; where as Trichophyton and fruit had the highst positivies among the molds and foods. 6. Dust and mites were the most common allergens with positive reaction of 54.5%; 56.3% in the acute; chronic urticarias; while animal dander was most common allergens with positive in 68.3% of patients with factitious urticaria. 7. In acute urticaria; prick test positive allergens were in descending order of house dust; Dermatophagoides farinae; human hair; hay dust. 8. In chronic Urticaria; house dust; hay dust; cat fur; mixed threshings; Dermatophagoides pteronyssinus; Dermatophagoides farinae in descending order. 9. In factitious urticaria; house dust; Cat fur; Dermatophagoides pteronyssinus; Dermatophagoides Jarinae; hay dust in descending order.
