Immunotherapy and new treatments.

Abstract

Purpose of review: This review comes at a time where new techniques in immunotherapy administration are being developed, new innovations are being incorporated to standard techniques, and new regulations are being adopted regarding the creation and storage of allergen extracts. Prior to the release of updated practice parameters regarding allergic rhinitis and immunotherapies, this review article provides a synopsis of current recommendations, a comparison of the practices in the United States and those of Europe, and an examination of experimental methods that are being studied.

Recent findings: This article seeks to review and discuss the various methods of administration, build up schedules, efficacy, effect on other atopic symptoms, and safety associated with allergen immunotherapy.

Summary: Innovations in standard techniques, such as new allergoids for SCIT, appear to be effective in improving symptoms and increasing IgG levels for grass allergens. Data for newer techniques is less clear. There appears to be increased treatment-related adverse events for ILIT, worse symptom scores compared with placebo for IDIT, and insufficient studies regarding the effectiveness of EPIT for aeroallergens. New regulations seek to standardize the documentation, storage, and creation of allergen extracts.
