Delivery of immunotherapy by the sublingual route (SLIT) continues to be used in clinical practice in many European countries, and studies are underway in the United States. The World Allergy Organization (WAO) published the first position paper on sublingual immunotherapy in 2009 to identify the indications, contraindications, and practical aspects of the treatment. (Canonica et al 2009) WAO has now completed and published the 2013 update of the position paper. (Canonica et al 2014)
Sublingual immunotherapy: World Allergy Organization Position Paper 2013 Update
Canonica GW, Cox L, Pawankar R, Baena-Cagnani CE, Blaiss M et al. Sublingual immunotherapy: World Allergy Organization position paper 2013 update. World Allergy Organization Journal 2014; 7:6 (28 March). doi:10.1186/1939-4551-7-6
The paper presents guidelines for sublingual immunotherapy based on the World Health Organisation (WHO) model of recommendations. In addition, the document defines unmet needs as identified by analysis of recent and ongoing clinical trials in sublingual immunotherapy, and it makes recommendations for the methodology of future clinical trials worldwide.
Chairpersons Giorgio Walter Canonica, MD, Linda Cox, MD, and Ruby Pawankar, MD, PhD, led a panel of 24 authors internationally known for their expertise in sublingual immunotherapy research and clinical practice. To further ensure a global scope to the project, WAO invited its regional, national, and affiliate member societies to participate in the development of the 2009 document as well as the 2013 update.
