Evaluation Of Prick Test In Atopic Dermatitis And Chronic Urticaria

Abstract

“Prick test” was carried out in 15 patients with atopic dermatitis (AD) and 10 patients with chronic urticaria (CU). Of the various aeroallergens tested, house dust mite (HDM), pollens, aspergillus furnigatus and insects were found to be most commonly positive. The common food allergens showing prick test positivity were egg white, fish, milk, brinjal, dal, groundnut and banana. Use of nasal filters showed 10-20% improvement in AD and 5 â€" 10% improvement in urticaria. Withdrawal of the responsible food article(s) showed 20-30% improvement in patients with AD and urticaria.
