Abstract:

Objective: To observe the changes on skin wheal and erythema of skin prick test for the patients with allergic rhinitis during SLIT. Methods: Since March 2010 the 103 cases of SLIT attacked by allergic rhinitis patients, divided into four age groups, respectively measured the diameter of skin wheal and erythema before treatment, six months, one year and 2 years after SLIT. The data were analyzed by analysis of variance method; P < 0.01 showed the difference was statistically significant. Results: The results showed that the most changes of skin erythema diameter were statistically significant in N1, N2, N3 age group during test observation compare with the data before SLIT (p < 0.01); and the most changes of allergen wheal diameter were not statistically significant, but the N4 group had no significant change of wheal and erythema diameter. Conclusion: Although most of the skin test wheal did not change significantly during the treatment of SLIT, the erythema reaction decreased to a certain extent, indicating that the intensity of histamine release may be reduced during the treatment.
