Abstract:
Non-steroidal anti-inflammatory drugs (NSAIDs) are the main triggers of drug hypersensitivity reactions. Such reactions can be pharmacologically or immunologically mediated, but in both cases individual susceptibility can be influenced by genetic factors. Polymorphisms in centrosomal protein of 68 kDa (CEP68) have been associated with pharmacologically mediated NSAIDs reactions. Here, we evaluated this gene in immunologically mediated single-NSAID-induced urticaria/angioedema or anaphylaxis (SNIUAA) by analyzing 52 single nucleotide polymorphisms in CEP68 in 176 patients and 363 NSAIDs-tolerant controls. Two intronic variants (rs2241160 and rs2241161) were significantly associated with an increased risk of SNIUAA, suggesting CEP68 to be a key player in both types of NSAIDs hypersensitivity. However, we found no overlap with genetic variants previously associated with pharmacologically mediated hypersensitivity, pointing to a complex role for this gene and its potential use in the development of biomarkers of clinical utility to diagnose patients at risk of these reactions and to differentiate entities.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
