Research regarding the use of sublingual immunotherapy The current understanding of clinical efficacy, safety, mechanisms and indications for the use of sublingual-swallow immunotherapy (SLIT) in the treatment of allergies is embodied in the studies, papers and publications referenced in this document. Over 280 citations are contained in this bibliography, including over 90 peer-reviewed studies published since 1995.
Internationally, SLIT is used widely (50% 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 2007, for the second time (originally in 2001), an international workgroup, including U.S. allergists, published the ARIA (Allergy Rhinitis and its Impact on Asthma) guidelines indicating SLIT as a viable treatment approach. The ARIA paper indicates that not only is there more modern research on SLIT compared to SCIT, but it is also of higher quality in terms of the WHO guidelines for research studies. A Cochrane Review, the most trusted independent, evidence based, meta-analysis organization in the world, released their analysis in 2003 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 have shown that SLIT was not effective, and those results are equivocal or dated.
Additional research efforts are underway in the U.S. and internationally; this document has been plagerized from Allergychoices and is updated periodically to include further publications. Last updated 08/18/2008
