title: A study of skin sensitivity to various allergens by skin prick test in patients of nasobronchial allergy.
abstract: OBJECTIVE
  To study skin sensitivity to various allergens in patients of nasobronchial allergy.
  
  
  METHODS
  2880 skin prick tests with 60 allergens were performed in 48 patients of nasobronchial allergy.
  
  
  RESULTS
  Most common offending allergens were insects (21.2%), followed by dusts (12.0%), pollens (7.8%), animal dander (3.1%), and fungi (1.3%). The common insect antigen were locust female (33.3%) followed by locust male (25%), grasshopper (20.8%), cricket (16.7%), cockroach female (16.7%) and cockroach male (14.6%). Common dust allergens were house dust, wheat dust, cotton mill and paper dust. Among pollens, Amaranthus spinosus, Argemone mexicana, Adhatoda vasica, Ailanthus and Cannabis were found to be common allergens. In animal danders common offending allergens were cow dander and dog dander. Among fungi Aspergillus fumigatus, Aspergillus flavus, Alternaria teneis and Fusarium sodani were common allergens. Patients of bronchial asthma had associated allergic rhinitis in 80% cases.
  
  
  CONCLUSIONS
  Common allergens in patients of nasobronchial allergy were identified. The data may prove useful in of allergen avoidance and immunotherapy in these patients.
