Pareto Analysis of Allergens for Lung-heat Type Allergic Rhinitis

Objective Pareto analysis of allergens for lung-heat type allergic rhinitis was carried out for the exploration of its remote causes.Methods A prospective study was applied in lung-heat type allergic rhinitis outpatients adopted from December,2010 to December,2011 in otorhinolaryngology department.Serum specific IgE and allergens were detected in the patients.Pareto analysis was used for the screening of important food allergens or inhalation allergens in patients with positive serum specific IgE.Results The total positive rate for serum specific IgE was 94.2% in the patients with lung-heat type allergic rhinitis.The main food allergens were eggs(48.1%),milk(24.8%)and shrimp(15.3%),and the main inhalation allergen was acari(40.9%).The difference of inhalation allergen percentage was insignificant between the male patients and the female patients(P0.05).Female patients had higher egg-allergen positive rate(58.8%)than the male(37.7%),and the difference was significant(P0.05).However,the differences of milk-allergen positive rate and shrimp-allergen positive rate were insignificant(P0.05).Conclusion In general words,acari and eggs are the predominant allergens for lung-heat type allergic rhinitis,and then come milk and shrimp.Serum specific IgE is one of the sensitive diagnostic indexes for allergic rhinitis.
