We learn with nice curiosity the research by Jiménez-Sánchez et al,1 which investigates the genetic structure of nonsteroidal anti-inflammatory drug (NSAID)-induced acute urticaria/angioedema (NIUA). By figuring out vital associations between polymorphisms in IL4RA (rs1805010) and FCER1A (rs2494250) and the danger of NIUA, Jiménez-Sánchez et al,1 present compelling proof linking pharmacologic hypersensitivity with an atopic genetic background. Particularly, each variants had been related to larger complete IgE ranges in sufferers with NIUA, whereas rs1805010—however not rs2494250—moreover correlated with elevated Dermatophagoides pteronyssinus (DP)-specific IgE ranges,1 strongly suggesting the existence of a “hybrid endotype” (ie, a scientific entity by which IgE-mediated priming intersects with COX-1 inhibition–pushed cysteinyl-leukotriene overproduction).
