Abstract

Background

To present the characteristics of drug hypersensitivity reactions (DHR) among iron preparations and to describe the outcomes of rapid drug desensitization (RDD) and drug provocation tests (DPT) of ferric carboxymaltose (FCM).

Methods

The retrospective descriptive study comprised patients with hypersensitivy to iron supplements. Low-risk according to the index reaction with iron, 10 patients underwent a 4-step DPT with FCM; an 11-step RDD protocol was administered to 21 patients not classified as low-risk. RDD success was evaluated for each cycle separately, defining successful completion as the implementation of all steps in both RDD and DPT protocols without subsequent early and/or late reactions.

Results

Among the 21 patients (mean age: 41.73 ± 10.98 years, all female) hypersensitive to iron underwent FCM RDD, 20 patients (95.2%) successfully completed FCM treatment with RDD. RDD failed in only 1 patient (4.8%). The total number of desensitization cycles was 29, of which 28 (96.5%) were successful. Urticaria was the most common breakthrough hypersensitivity reaction and observed in 7 (33.3%) patients. Ten patients received FCM with DPT. The iron replacement therapy for these 10 patients was successfully completed. Urticaria developed in 2 patients after the completion of DPT.

Conclusions

RDD is a dependable procedure facilitating the efficient delivery and completion of FCM treatments in patients with iron hypersensitivity. Additionally, FCM can be applied with DPT in low-risk patients.

期刊介绍： The official pubication of the World Allergy Organization, the World Allergy Organization Journal (WAOjournal) publishes original mechanistic, translational, and clinical research on the topics of allergy, asthma, anaphylaxis, and clincial immunology, as well as reviews, guidelines, and position papers that contribute to the improvement of patient care. WAOjournal publishes research on the growth of allergy prevalence within the scope of single countries, country comparisons, and practical global issues and regulations, or threats to the allergy specialty. The Journal invites the submissions of all authors interested in publishing on current global problems in allergy, asthma, anaphylaxis, and immunology. Of particular interest are the immunological consequences of climate change and the subsequent systematic transformations in food habits and their consequences for the allergy/immunology discipline.
