Research regarding the use of sublingual immunotherapy
You’ll find the most current understanding of the clinical efficacy, safety and use of sublingual immunotherapy (SLIT) for allergy treatment is embodied in the studies, papers and publications referenced in this document. Over 160 citations are contained in this bibliography, including over 70 peer-reviewed studies published since 1995.
Internationally, SLIT is used widely (50-75% in some European countries), with full regulatory and government backing. U.S. allergy leaders are writing in support of SLIT. (See section 1) The World Health Organization indicated its use in its 1998 position paper. In November 2001, an international workgroup, including U.S. allergists, published the ARIA (Allergy Rhinitis and its Impact on Asthma) guidelines indicating SLIT as an effective alternative as well. Since that time, dozens of well-designed studies (randomized, double-blind, placebo-controlled) have been peer reviewed and published. Cochrane Review has performed a meta-analysis and determined SLIT both safe and effective (see section 1).
Two additional pivotal studies to note are the “10 year study…” showing the long lasting effect of SLIT (see section 1), and the 2004 head-to-head study of SLIT to injection in a double-blind, double-dummy approach (see section 2). Few studies (two) could be found showing that SLIT was not effective, and those results are equivocal and dated.
Additional research efforts are underway in the U.S. and internationally, this document will updated periodically to include further publications.
