Demoly Allergy 2003: 58: 854–863 Position paper • The indications for drug provocation testing can be divided into 4 groups that are intertwined: • To exclude hypersensitivity– in history not suggestive of hypersensitivity to the drug and in patients with nonspecific symptoms, such as vagal symptoms by local anesthesia

Demoly Allergy 2003: 58: 854–863 A drug provocation test is the controlled administration of a drug in order to diagnose hypersensitivity reactions The challenge test should be done under medical supervision for an alternative drug, structurally or pharmacologically related to the suspect medicine. The provocation test drug is also known as challenge or controlled re-challenge, drug challenge, incremental challenge, re-challenge or test of tolerance.

Demoly Allergy 2003: 58: 854–863 Regarding the limitations of drug provocation test, consider the "gold standard“ to establish or refute the diagnosis of hypersensitivity to a substance. Although allergic symptoms can be reproduced, so can the adverse reaction by another mechanism After provocation test,it is desirable to keep the patient under observation for 24 hours,but local restrictions may affect this ideal
Protocol of nasal aspirin challenge Basal nasal symptoms, nasal inspiratory flows and volumes are recorded during the first 30 minutes every 10 minutes. Then for the evaluation ofspecific nasal hyperreactivity,are challenged with 0.9% NaCl (80 ul) instilled into each nostril with an Eppendorf pipette. E. Nizankowska-Mogilnicka, G. Bochenek, L.

Protocol of nasal aspirin challenge Nasal symptoms, nasal inspiratory flow and volume are measured within 30 minutes every 10 minutes. If there is a change from20% in the values recorded upper airway is hyperreactive and therefore the challenge can not be done. Finally, 80 ul of L-ASA are instilled into each nostril (total aspirin dose: 16 mg) E. Nizankowska-Mogilnicka, G. Bochenek, L. Mastalerz, M. S´wierczynska, C. Picado,et al.

Lee Clin Exp Allergy 2005; 35:717–722 In conclusion, a history of previous reaction after ingestion of aspirin is not a reliable guide to the diagnosis of aspirin hypersensitivity (AH). Since there is no other in vitro test of AH,the challenge of aspirin is the only diagnostic tool available

M. Pilar Berges-Gimeno and Donald D. Stevenson JOURNAL OF ASTHMA Vol. 41, No. 4, pp. 375–384, 2004 Desensitization is a term used in a broad sense, refers to the elimination of reactions to ASA byrepeated exposure and increasing doses of medication
Tips • During the desensitization with ASA, there is a continuous inhibition of COX-1 and of phospholipase A2. This leads to a decrease in the synthesis of LTs and prostanoids. • Recipients (patients) cysLT1 are "down regulated“, then there is a "leveling" of the effects of the LTs. Studies have shown that during acute desensitization there is a slight decrease in TXB2 and LTB4. • During chronic desensitization, the synthesis of LTB4 substantially decreases Ferreri NR, Howland WC, Stevenson DD, Spiegelberg HL.

General requirements for aspirin desensitization ASA desensitization should be performed ina place capable of providing advancedcardiac care, ventilator support and continuous monitoring by qualified personnel. Thesupervising physician must be available immediately to the bedside of the patient after the drug is first applied, and recognize early warning signs.

In a long-term study of65 patients with ASAintolerance who underwent desensitization, there was a significant decrease in the number of infectious sinusitis and the use of prednisone with improvement in smell and symptoms of asthma and rhinitis. The need for sinus surgery decreased from one every 3 years to once every 9 years.

Asubsequent study by Berges-Gimeno and colleagues with172 patients demonstrated a percentage improvement of 67% patients at 6 months of treatment, which persisted for 1 to 5 yearswith reduction in the occurrence of purulent sinusitis about 5 episodes per year to less than half Berges-Gimeno, P, Simon RA, Stevenson DD.
