Free Content Future directions in allergen immunotherapy

Download Article:
Both subcutaneous immunotherapy (SCIT) and sublingual immunotherapy (SLIT) are effective clinically against allergic rhinitis and allergic asthma, and modify the underlying immunologic abnormalities. Despite this, many patients who could benefit from receiving SCIT and SLIT do not because of concerns about safety and the inconvenience in receiving SCIT, and the long duration of treatment with both, 3‐4 years being required for lasting benefit. Attempts to improve the efficacy and safety, and to shorten the course of allergen immunotherapy have taken many approaches. Some approaches have generated great enthusiasm, only to fail in larger trials and be discarded. Other approaches show some promise but perhaps not enough to achieve regulatory approval. Those approaches that seem to have the best chance of becoming available in the next few years include the following: intralymphatic and epicutaneous immunotherapy, vitamin D in patients with insufficient serum 25 hydroxy vitamin D, probiotics, and allergoids, but all require further studies before being ready for nonexperimental use or, where necessary, for regulatory approval.

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.

    The journal is indexed in Thomson Reuters Web of Science and Science Citation Index Expanded, plus the National Library of Medicine's PubMed service.
