Background:
It has been identified shared allergens from whole body between Blatella germanica and Periplaneta americana. It has been reported high correlation between both cockroaches.
Objective:
To estimate correlation between skin test for two major species of intradomiciliary cockroaches.
Methods:
It was included patients with clinical diagnostic of allergy pathology whom attended to external consult of Allergy and Clinical Immunology Service of the Hospital Universitario de Puebla in a period of six months, prick skin tests with standardized antigens of Blatella germanica and Periplaneta americana were made.
Results:
One hundred twenty patients were enrolled in the study, 54.2% were women and 45.8% were men, with a mean age of 15.7 years old. The correlation coefficient between Germany cockroach and American cockroach to erythema was 0.49 and to papule was 0.40.
Conclusion:
The outcomes showed a moderate correlation or a considerable relation between both cockroaches whether erythema or papule. Based on the results presented, we suggest to evaluate both antigens in order to improve diagnostic accuracy.
