Abstract:
Objective To study the distribution of sepecific immunoglobulin E(SIgE) and its relationship with the total immunoglo-(bulin) E(TIgE) in children with respiratory allergic disease.Methods Serum SIgE was measured in 209 children with asthma,allergic rhinitis,cough variant asthma and asthmatic bronchitis by Pharmacia UniCAP100E system.The SIgE included the SIgE antibodies to fx5E(egg albumen,milk,fish,wheat,peanut,soybean),hx2(house dust,dermatophagoides culinae,dermatophagoides pteronyssinus,cockroach),ex1(scurf of cat,horse,cow and dog),mx1(penicillium notatum,helminthosporium halodes,aspergillums furngatits,alternaria allcrnata,),f23(crab),f14(shrimp),w14(amaranthaceae),T21(cajeput) and i8(moth).Serum TIgE was also detected in 132 patients.Results 1.The positive detection rate of SIgE in patients aged from 3 to 14 years were 72.81% which were higher than that of aged from 40 days to 3 years old(57.89%).2.The SIgE detection rate of fx5E,hx2 and ex1 were 81.8%,32.73% and 16.36% respectively in patients aged from 40 days to 3 years old;but that of hx2,fx5E,i8,w14,f24 and ex1 were 78.31%,48.19%,24.10%,24.10%,15.66% and 15.66% respectively in patients aged from 3 to 14 years.3.The positive detection rate of SIgE was related with that of TIgE.The detection rate of combined SIgE and the TIgE was 83.33%.Conclusions 1.The lower detection rate of SIgE in patients aged from 40 days to 3 years may be due to the wheezing in infants partially induced by the acute infection and congenital airway disease.2.The most common allergens in children aged from 40 days to 3 years were fx5E,hx2 and ex1.But that of patients aged from 3 to 14 years were hx2,fx5E,i8,w14,f24 and ex1.3.The combined detection of the SIgE and the TIgE may increase the positive rate and diagnose the patients with respiratory allergic disease effectively.
