Abstract

Fifty-one atopic asthmatic and/or allergic rhinitic children and 23 nonatopic control from Santo Domingo, the Dominican Republic, were skin tested with an extract mix of three cockroach species (Blattella germanica, Blatta orientalis, and Periplaneta americana). Sixteen percent of the atopics and none of the nonatopics demonstrated positive immediate skin reactions to the cockroach mix (χ2 = 4.05, p = 0.04). Hypersensitivity was correlated with the duality of the homes; 22% (8/36) of the atopics who lived in a concrete home were skin test positive to the cockroach mix, while none (0/15) of the atopics who lived in a wood home were skin test positive (χ2 = 4.86, p = 0.03). Although the incidence of cockroach allergy in this study is lower than that found elsewhere, these data support the notion that, in this tropical environment, sensitization to cockroaches is associated with housing quality.
