The diagnosis of ASA-intolerance is based usually on a history of adverse reactions caused by the ingestion of NSAIDs. Although the majority of ASA-hypersensitive patients have a convincing history of NSAID-induced adverse reactions, in some patients confirmation by controlled aspirin challenge is necessary. Oral aspirin challenge is the gold standard to confirm the diagnosis. Nasal or bronchial provocation with lysine-ASA, which is available in Europe, may be a valuable alternative diagnostic tool (15). Nevertheless, oral, bronchial or intranasal challenges are time consuming and require special equipment and expertise, which is not always available.
Aspirin Reaction Mechanisms? - The Student Room
Other arachidonic acid metabolites generated by the 5-lipoxygenase pathway have been associated with aspirin-hypersensitivity. For example, aspirin triggers 15-HETE generation in nasal polyp epithelial cells and peripheral blood leukocytes from aspirin-intolerant but not aspirin-tolerant patients suggesting the presence of a specific abnormality of the 15-LOX pathway in these patients. Upregulation of 15-lipoxygenase and decreased production of lipoxin A4, an anti-inflammatory 15-LO metabolite found in leukocytes and nasal polyp tissue from ASA-intolerant patients, further points to a distinctive but not yet understood role for the 15-lipoxygenase pathway.

Aspirin® is the trademark for ester - acetylsalicylic acid - which is a prescription-free drug, used in the therapy of painful, inflammatory and feverish states. The active ingredient in Aspirin also prevents infections and damage to blood vessels. The efficiency of any drug depends on its chemical stability. Hydrolysis of the drug can be a major reason for the instability of drug solutions. Thus, when Aspirin undergoes hydrolysis, the degradation products are salicylic acid and acetic acid.

The mechanism of action of aspirin.
Successful management of chronic rhinosinusitis is essential and may result in the improvement of asthmatic symptoms (21). Topical steroids are quite effective in controlling symptoms of rhinitis and may slow down recurrence of nasal polyps. Antibiotics should be used whenever infectious component is evident. Although antileukotriene drugs (ALD) may also alleviate symptoms of chronic rhinosinusitis and improve nasal patency in AERD patients, they are not more effective than in ASA-tolerant patients (22). Surgical procedures (polypectomy, functional endoscopic sinus surgery or ethmoidectomy) are usually needed to relieve symptoms of chronic rhinosinusitis at certain stages of the disease and to remove polypoid tissue from sinuses. Assessment of the outcome of endoscopic surgery in ASA-sensitive patients with chronic rhinosinusits and ASA-tolerant controls revealed that patients with ASA-triad responded less well to surgical intervention (23). Because surgery does not affect the underlying inflammatory component of rhinosinusitis, medical treatment with topical steroids is also necessary post-surgery. Antileukotrienes and/or chronic oral aspirin after desensitization may also be considered as the follow up treatment after surgery.
