Unanswered Questions and Warnings Involving Anti–Immunoglobulin E Therapy Based on 2-Year Observation of Clinical Experience
The relatively rapid development and deployment of a clinically useful monoclonal antibody omalizumab has produced a number of questions still not answered despite massive research and many clinical trials. The mechanism of action as down-regulation of FceR1 receptors in the presence of low free immunoglobulin E (IgE) is incomplete. Some severe allergic asthmatic patients respond almost immediately, others take months, and some never respond. No accounting for the possible antigen sweeping by the complexes of IgG–IgE has been reported. Skin tests may remain positive for much longer than reported, raising the possibility of anaphylaxis with concomitant specific immunotherapy. Two cases of anaphylaxis to specific immunotherapy while being "covered" with anti-IgE are reported. Total IgE levels do not always rise as expected, six cases of static IgE levels in responders are reported. Total IgE levels do not dependably predict usefulness. Current guidelines for anti-IgE use in asthmatic patients may require reexamination as data from broad clinical experience are gathered.

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.
