3 NSAIDs are the drugs more frequently prescribed worldwide Drugs most frequently involved in hypersensitivity drug reactions Doña I JIACI 2012 Selective 24% Selectivos 156 (24%) Cross Intolerant 76% Intolerancia cruzada 503 (76%) Doña I CEA 2011

4 CLASSIFICATION Type of reaction Clinical manifestation Timing Underlying disease Cross reactivity Putative mechanism NSAIDs exacerbated respiratory disease (NERD) NSAIDs exacerbated cutaneous disease (NECD) NSAIDs induced urticaria/angioede ma (NIUA) Single NSAIDs induced urti/angio/ anap (SNIUAA) Single NSAIDsinduced delayed reactions (SNIDR) Rhinitis/asthma Acute Asthma/ rhinosinusitis Urticaria/angioe dema Urticaria/angioe dema Urticaria/angioe dema/anaphyla xis various symptoms and organs involved Delayed Chronic urticaria No underlying chronic diseases No underlying chronic diseases No underlying chronic diseases YES Nonallergic Cox-1 inhibition Cox-1 inhibition Unknown, probably COX-1 inhibition NO Allergic IgE-mediated T cell mediated ENDA NSAID TF (Kowalsky M, 2013)

5 Mediators release SAME MECHANISM??

6 NSAIDs exacerbated respiratory disease (NERD) NSAIDs induced urticaria/angioedema (NIUA) REPRESENT <10% of all CI Doña I, 2011 MOST COMMON MANIFESTATION: 60% of all CI Doña I, 2011 Reaction related to COX COX inhibition inhibition potency COX inhibition?? Reaction to different chemically-unrelated NSAIDs

7 NERD CLINICAL MANIFESTATIONS CHRONIC RS POLYPOSIS ASTHMA

8 NERD NATURAL HISTORY RHINITIS ASTHMA NSAID INTOLERANCE VIRUS TOBACCO CONTAMINATION

9 NSAIDs induced urticaria/angioedema (NIUA) CLINICAL MANIFESTATIONS Healthy subjects WITHOUT chronic urticaria Cutaneous response (urticaria/ae) after intake of different NSAIDs 60% of all CI: the most common manifestation Natural history: present in children Atopy as risk factor?

12 Non-immunological mechanisms: COX hypothesis A. Szczeklik in 1975 NSAIDs with different chemical structures induce the same pattern of reactions NSAIDs capacity for inducing reactions directly positively correlates with the COX-1 inhibitory potency Non immunological mechanism (Szczeklik A, 1975; Szczeklik A, 1977; Stevenson DD, 1990; Quiralte J, 1996)
