Olea sublingual allergoid immunotherapy administered with two different treatment regimens
Sublingual immunotherapy (SLIT) with monomeric carbamylated allergoid administered in accordance with the standard regimen has proven to be effective and safe. Achieving clinical benefit, however, requires a lengthy period of time so it is not very suitable for short-lasting allergies. We thus performed this study to compare an administration protocol starting in the coseasonal period (with a 4-day build-up phase) with a precoseasonal scheme to verify if the former regimen provides the same benefit in a shorter period of time. The prospective, randomized, drug therapy‐controlled study was conducted in 33 rhinitic patients monosensitized to Olea with or without asthma. Ten patients were assigned to the coseasonal therapy with 5000 allergic units (AU)/week for 6 weeks, 11 to the precoseasonal therapy with 3000 AU/week for 10 weeks, and 12 to drug therapy. They were treated from April or May to June 2008. A visual analog scale (VAS) was performed at baseline and after treatment to assess the well being of the patients. Drug consumption was evaluated by means of a monthly diary. There was greater VAS improvement in both the SLIT groups versus the controls, but it was statistically significant only in the coseasonal group (p < 0.01). Furthermore, there was a reduction in the rescue medication only in the coseasonal SLIT (p < 0.05 versus drug therapy). One mild adverse event was observed. The allergoid SLIT was shown to be effective and safe in Olea allergy in particular when a coseasonal regimen was used.

More about this publication?
- Allergy and Asthma Proceedings is a peer reviewed publication dedicated to distributing timely scientific research regarding advancements in the knowledge and practice of allergy, asthma and immunology. Its primary readership consists of allergists and pulmonologists.
The goal of the Proceedings is to publish articles with a predominantly clinical focus which directly impact quality of care for patients with allergic disease and asthma and by having the potential to directly impact the quality of patient care. AAP welcomes the submission of original works including peer-reviewed original research and clinical trial results. Additionally, as the official journal of the Eastern Allergy Conference (EAC), AAP will publish content from EAC poster sessions as well as review articles derived from EAC lectures.
Featured topics include asthma, rhinitis, sinusitis, food allergies, allergic skin diseases, diagnostic techniques, allergens, and treatment modalities. Published material includes peer-reviewed original research, clinical trials and review articles.
Articles marked "F" offer free full text for personal noncommercial use only.
