The role of Immunoglobulin E and immune inflammation: Implications in allergic rhinitis

Competing interests: The authors have declared that no competing interests exist. In a study recently published in PLOS Medicine , Custovic and colleagues [ 1 ] report an elegant analysis of the results of specific Immunoglobulin E IgE assays on sera from a birth cohort that they have studied in detail over the last 15 years. The primary objective was to evaluate the relationship of the results to the diagnosis of current asthma. However, the authors have employed a new network analysis method, which is improved over previous methods because it can capture nonlinear relationships and does not rely on assumption of a parametric probability. As the authors show, this approach can lead to improved sensitivity and specificity.

Targeted therapy in severe asthma today: focus on immunoglobulin E

In a physician observed, following a blood transfusion, a case of transient asthma caused by allergy to horse dander. This was the first indication of a factor in blood capable of mediating an allergic reaction. The search for reagin started after that, but until the 's it was thought that reaginic activity was not a single, indivisible molecular species but was present in allergic sera in the form of labile complexes. This differed radically from immune antibodies that were known at the time.

Immunoglobulin E IgE plays a critical role in the allergic inflammatory process in diseases such as allergic rhinitis. Cross-linking IgE bound to its receptor on cells by multivalent allergens initiates a chain of events resulting in allergic immune responses. Mast cells and basophils are involved in the early, immediate response, which is marked by cellular degranulation and the release of proinflammatory mediators, including histamine. Antigen-presenting cells are also activated by allergen-loaded IgE, resulting in immunomodulation of T-cell responses.

Asthma is one of the most common respiratory diseases encountered in clinical practice. Although the vast majority of asthmatics can be adequately controlled with inhaled steroids and other preventer medications, a small proportion remain uncontrolled. Anti-IgE treatment with omalizumab has been proposed in patients as a preferred approach in step 5 asthma therapy according to GINA guidelines.
