Analysis of concentration allergenspecyfic IgE against non-steroidal anti-inflammatory drugs in own material (summary)
Kinga Lis, Zbigniew Bartuzi
Introduction. Nonsteroidal anti-inflammatory drugs (NSAIDs) currently occupy a leading position in the frequency of drug-induced hypersensitivity reactions. Aim. The present paper analyses referrals for laboratory tests with regard to determination of NSAIDs-specific IgE as well as the results of these tests. The abovementioned referrals were sent to the Immunological and Allergological Laboratory of the Department of Allergology, Clinical Immunology and Internal Diseases at University Hospital No. 2 in Bydgoszcz between 17.04.2012 and 16.04.2017. Material and methods. The analysis took into account age and sex of patients, number of referrals, the type of drugs for which IgE determination had been ordered, as well as accompanying tests. The obtained results were analyzed for the presence of specific IgE. Results. It was observed that the asIgE determined for NSAIDs accounted for 2.47% of all referrals that had been received by the laboratory. The orders included asIgE for the following drugs: acetylsalicylic acid, paracetamol, ibuprofen, ketoprofen and pyralgine. The most commonly ordered laboratory test was asIgE for aspirin, less often for ketoprofen, ibuprofen, paracetamol and metamizole. Half of the referrals for NSAIDs-specific IgE were combined with referrals for asIgE for other allergens and their mixtures. Only one positive ketoprofen-specific IgE test result was obtained. Conclusions. The analysis of test results suggests non-IgE mediated bases of hypersensitivity symptoms associated with NSAIDs or other undetermined causes not connected with these drugs. Keywords: hypersensitivity, allergy, non-steroidal anti-inflammatory drugs (NSADIs), IgE, referral for laboratory tests
