Sublingual Immunotherapy in Patients with Allergic Rhinoconjunctivitis
- 94 Downloads
Sublingual immunotherapy (SLIT) is a well-established treatment option for allergic rhinitis in several European countries, but it is considered investigational in the United States. Studies conducted in Europe provided a large body of evidence supporting the safety and efficacy of SLIT, but those studies used allergen products that are different from those that are likely to be approved in the United States, and many of them were not controlled, randomized, double-blinded trials. This review summarize research conducted on the efficacy, safety, and mechanisms of SLIT published during the past year, with a focus on ragweed and grass antigens. Results of recent US studies document the safety and efficacy of SLIT and have started to yield insight into the mechanisms of SLIT.

This study was significant in that it showed that standardized, glycerinated short ragweed pollen extract administered sublingually at maintenance doses of 4.8 to 48 μg Amb a 1/d was safe and induced favorable clinical and immunologic changes in ragweed-sensitive individuals.

This is an important review that identified deficiencies and sources of considerable heterogeneity in both design and data interpretation of published SLIT studies, with the hope that recommendations provided will allow the conduct of more adequately designed SLIT trials to facilitate the appropriate placement of SLIT therapy to treat patients with allergic rhinoconjunctivitis.

In Press, J Allergy Clin Immunol 2011. This study and that by Blaiss et al.  are important due in part to their large sample sizes, rigorous design, and large effect sizes detected (larger than those of many drugs currently in use to treat allergic rhinoconjunctivitis). Moreover, given its convenient administration, no dose build-up requirement, safety profile, and efficacy, this form of SLIT may become an important addition to the allergic rhinoconjunctivitis treatment armamentarium of North American adults. The cross-reactivity of Timothy grass with Festucoideae is also likely to be important. Google Scholar
