Non-allergic Hypersensitivity Reactions to Immunoglobulin Preparations in Antibody Deficiencies: What Role for Anti-IgA IgG and Complement Activation?
The presence of IgG anti-IgA in the serum of primary immunodeficiency (PID) patients has long been considered responsible for hypersensitivity (HS) to immunoglobulin preparations (IgPs), but this link is increasingly being questioned. The aim of this work was to describe the prevalence of IgG anti-IgA and its association with HS, and to explore a new pathophysiological hypothesis involving the complement system. We measured IgG anti-IgA, using a standardised commercial technique, in controls and PID patients, and compared our results to a systematic literature review. We measured complement activation in PID patients before and after IgP infusion, and in vitro after incubation of IgP with serum from controls and PID patients. IgG anti-IgA was detected in 6% (n = 2/32) of PID patients, 30% (n = 3/10) of selective IgA deficiency patients and 2% (n = 1/46) of healthy controls. In the literature and our study, 38 PID patients had IgG anti-IgA and HS to IgPs and 9 had IgG anti-IgA but good tolerance to IgPs. In our patients, we observed a constant complement activation after IgP infusion compared to baseline. In vitro, IgP induced significant complement activation with all sera from tested individuals. IgA immunisation is not rare in PID, higher in selective IgA deficiency, but may also occur in healthy controls. Our results question the clinical relevance and pathophysiological implication of IgG anti-IgA in the context of HS with IgPs. Complement activation-related pseudoallergy could explain the clinical characteristics and natural history of HS symptoms.
期刊介绍:
Clinical Reviews in Allergy & Immunology is a scholarly journal that focuses on the advancement of clinical management in allergic and immunologic diseases. The journal publishes both scholarly reviews and experimental papers that address the current state of managing these diseases, placing new data into perspective. Each issue of the journal is dedicated to a specific theme of critical importance to allergists and immunologists, aiming to provide a comprehensive understanding of the subject matter for a wide readership.
The journal is particularly helpful in explaining how novel data impacts clinical management, along with advancements such as standardized protocols for allergy skin testing and challenge procedures, as well as improved understanding of cell biology. Ultimately, the journal aims to contribute to the improvement of care and management for patients with immune-mediated diseases.
