Background: The European Network for Drug Allergy (ENDA) proposed a consensus document for hypersensitivity reactions to nonsteroidal anti-inflammatory drugs (NSAIDs) in 2011. A subgroup of patients with NSAIDs-exacerbated respiratory disease (NERD) develop urticaria/ angioedema type reactions in response to NSAIDs. The Kalyoncu classification might be a novel option to classify patients with NSAID hypersensitivity (NH). In this study, we compare the ENDA and the Kalyoncu classifications. Methods: This study enrolled a total of 196 patients. NH reaction types were categorized as asthma, rhinitis, urticaria/angioedema and anaphylaxis. Based on the reaction history and oral provocation test findings, patients were grouped according to ENDA and Kalyoncu classifications. Results: The mean age of the 196 patients was 40.32±13.28 years, and 130 (66.3%) of them were female. Under the ENDA and Kalyoncu classifications, the most common NH subgroups were NERD (32%), and isolated NH (34.2%), the least prevalent NH subgroups were single NSAID-induced delayed reactions (SNIDR) (1.5%), and pseudo Samter’s syndrome (11.7%). Conclusions: Our research revealed that the Kalyoncu classification is more descriptive of patients with NERD exhibiting urticaria/angioedema-type reactions. It also provides future risk assessment for development of NERD. For controversial cases, the Kalyoncu classification can be utilized as a new complimentary option alone or in conjunction with ENDA classification. |
