Long-Term Control of Dust Mite Allergies With Sublingual Immunotherapy

World Allergy Organization (WAO) 2010 International Scientific Conference. Presented December 7, 2010 (Dubai, United Arab Emirates) — Four years of sublingual immunotherapy (SLIT) was found to confer benefits that were maintained for 8 years post-SLIT, and response to retreatment at 8 years was more rapid than the initial response. In addition, 4 years of SLIT were found to be more cost-effective than 3 or 5 years in patients with house dust mite allergy, according to the results of a 15-year follow-up study.  The study involved 78 patients with a respiratory allergy to house dust mites; 59 completed the study. Researchers divided patients into 4 groups: pharmacotherapy (control group), SLIT for 3 years, SLIT for 4 years, and SLIT for 5 years. After treatment was stopped, the patients were followed for an additional 8 years.  In patients who received SLIT for 3 years, the effect persisted for 7 years. In those who received SLIT for 4 or 5 years, the effect persisted for 8 years. In all 3 SLIT groups, the symptoms and medication scores were significantly different from baseline starting from the first year of the study. This difference remained significant at every year until the end of the study.
