Abstract:
Objective To analyze the detection results and distribution characteristics of serum allergen-specific immunoglobulin(Ig)E antibodies in patients with type Ⅰ allergic diseases(hereinafter referred to as allergic diseases)in Chongqing,and to provide epidemiological data and diagnostic evidence for the prevention and treatment of allergic diseases.Methods A total of 9189 patients who underwent allergen-specific IgE an-tibody detection in this hospital from January 2023 to February 2024 were included in the study.The positive cases of allergen specific IgE antibodies detection were statistically analyzed according to age groups,genders,and sea-sons,and the distribution characteristics and patterns of specific allergens were analyzed.Results Among the 9 189 patients with allergic diseases,4 143 cases showed positive allergen-specific IgE antibodies detection results,with a positive rate of 45.09％.The proportion of patients with multiple sensitization was 68.53％.The main inhalant allergens included Dermatophagoides pteronyssinus(28.95％),Dermatophagoides farinae(23.62％),and Blomia tropicalis(10.95％);while the main ingested allergens were milk(7.57％),shrimp/crab(2.84％),and egg white(1.98％).The positive rate of inhalant allergens was higher than that of ingested al-lergens.The positive rate of allergens in males was higher than that in females(P＜0.05).The allergens in infants and toddlers under 3 years old were mainly ingested and mostly sensitized by single allergen.The posi-tive rate of allergens and multiple sensitization rate were the highest in patients aged 12-＜18 years.The pos-itive rate of allergens was the lowest in patients over 60 years old.The positive rate of allergens was the high-est in autumn,and Dermatophagoides pteronyssinus and Dermatophagoides farinae were the main allergens in all seasons.Conclusion Patients with allergic diseases in Chongqing exhibited the following characteristics:Dermatophagoides pteronyssinus and Dermatophagoides farinae are the main allergens,the positive rate of al-lergens in males is higher than that in females,the majority patients are 12-＜18 years old,and the disease is more prone to occur in autumn.These findings can provide a reference for the prevention and treatment of al-lergic diseases in this region.
