Inborn errors of immunity associated with elevated immunoglobulin E

Abstract

Objective: To review the characteristic clinical and laboratory features of inborn errors of immunity (IEI) that are associated with elevated immunoglobulin (Ig)E levels.

Data sources: Primary peer-reviewed literature.

Study selections: Original research articles reviewed include interventional studies, retrospective studies, case-control studies, cohort studies, and review articles related to the subject matter.

Results: An extensive literature review was completed to allow for comprehensive evaluation of several monogenic IEI. This review includes a description of the classic clinical features, common infections, characteristic laboratory findings, specific diagnostic methods (when applicable), and genetic basis of disease of each syndrome. A comprehensive flow diagram was created to assist them in the diagnosis and evaluation of patients with elevated IgE levels who may require evaluation for an IEI.

Conclusion: IEI should be considered in patients with elevated IgE levels, especially if they have recurrent infections, eczematous dermatitis, malignancy, lymphoproliferation, autoimmunity, or connective tissue abnormalities.
