OBJECTIVE: To evaluate the correlation between the routine diagnostic tests for house dust mite (HDM) sensitization in Chinese allergic rhinitis (AR) patients, including the skin prick test (SPT), serum HDM-specific immunoglobulin E (sIgE) and nasal smear eosinophilia.
METHODS: The ImmunoCAP assay was employed to detect serum total IgE and sIgE. The SPT and nasal smear eosinophil counts were performed using standard procedures.
RESULTS: Of 82 subjects with HDM-related symptoms and positive SPT results, 55 individuals showed an sIgE level equal to or greater than CAP class 1 for both Dermatophagoides pteronyssinus (Der p) and D. farinae (Der f), and 62 individuals demonstrated positive eosinophils in nasal smears. sIgE of Der p and Der f presented a linear correlation, and the level of serum HDM-sIgE was also positively correlated with total IgE. An increasing sIgE level was correlated with higher SPT grades in both Der p and Der f. Meanwhile, the correlation coefficient exhibited an increase in value with aging, and the 31- to 40-year age group demonstrated the highest value for both Der p and Der f.
CONCLUSION: The positive correlation between SPT and sIgE reaction to HDM varied according to the age of patients with AR.
