Abstract
OBJECTIVE: To evaluate the efficacy of sublingual immunotherapy (SLIT) with standardized Dermatophagoides farina drops in monosensitized and polysensitized patients with allergic rhinitis.
METHOD: The clinical data of 162 patients treated with standardized Dermatophagoides farina drops were analyzed retrospectively. These patients were divided into the monoallergen sensitized group and polyallergen sensitized group according to the results of skin prick tests. The total nasal symptoms score (TNSS), the total medication score (TMS) and adverse effects (AEs) were evaluated before treatment, 2 year after SLIT treatment and 3 year after drug discontinuance. Result:After SLIT treatment for 2 years and drug discontinuance for 3 years, the TNSS (3. 14[2. 47; 3. 65], 3. 45 [2. 76; 3. 92], respectively) and TMS (0. 42[0. 36; 0. 57],0. 35[0. 26; 0. 44], respectively) in the monoallergen sensitized group were lower than that before the treatment (TNSS: 9. 00 [8. 00; 10. 00], TMS: 2. 16 [1. 88; 2. 37]), which have showed a statistically significant difference(P<0. 05). Similarly, after SLIT treatment for 2 years and drug discontinuance for 3 years, the TNSS (3. 14[2. 46; 3. 63], 4. 23[3. 65; 4. 96], respectively) and TMS (0. 42[0. 36; 0. 58], 0. 50[0. 34; 0. 72], respectively) in the polyallergen sensitized group were lower than that before the treatment (TNSS: 9. 00[8. 00; 10. 00], TMS: 2. 18[1. 95; 2. 37]), which have showed a statistically significant difference(P<0. 05). No statistically significant finding could be observed in monoallergen and polyallergen sensitized group before the treatment and 2 years after treatment, respectively. However, a statistically significant finding could be observed between two groups in the drug discontinuance for 3 years (P<0. 05). Eleven patients suffered local adverse effects, and the incidence of adverse effects showed no significantly difference (P>0. 05).
CONCLUSION: SLIT with standardized Dermatophagoides farina drops has a long-term efficacy in monosensitized and polysensitized patients with allergic rhinitis. Moreover, a longer SLIT treatment (>2 years) may be necessary to consolidate its efficacy.
