After beta lactam antibiotics, hypersensitivity reactions to nonsteroidal antiinflammatory drugs are the second cause of hypersensitivity to drugs. Acute manifestations affect the respiratory tract (aspirin exacerbated respiratory disease), the skin (urticaria and angioedema), or are generalized (anaphylaxis). Correct diagnosis and treatment in order to prevent unnecessary morbidity and the pot...
The clinical syndrome of aspirin-exacerbated respiratory disease (AERD) is a condition where inhibition of cyclooxygenase-1 (COX-1) induces attacks of upper and lower airway reactions, including rhinorrhea and varying degrees of bronchospasm and laryngospasm. Although the reaction is not IgE-mediated, patients can also present with anaphylactic hypersensitivity reactions, including hypotension,...
Asthma and chronic rhinosinusitis are heterogeneous airway diseases of the lower and upper airways, respectively. Molecular and cellular studies indicate that these diseases can be categorized into unique endotypes, which have therapeutic implications. One such endotype is aspirin-exacerbated respiratory disease (AERD), which encompasses the triad of asthma, aspirin (or nonsteroidal anti-inflam...
Abstract Purpose of review Controlled oral provocation test with aspirin is considered the “gold standard” for diagnosing hypersensitivity to NSAIDs (non-steroid anti-inflammatory drugs). Newer techniques respiratory exposure tests, bronchial and nasal respectively, have been nonetheless developed, as they are safer, less likely cause a systemic reaction, time-consuming than (acetyl-salicylic a...
Aspirin-induced asthma (AIA) and aspirin-induced urticaria/ angioedema (AIU) are two major aspirin-related allergies. We summarize recent findings related to their molecular genetic mechanisms in order to identify genetic susceptibility markers for differentiating AIU and AIA. The overproduction of cysteinyl leukotriene has been suggested as a mechanism in both AIU and AIA. Increased expression...
Five patients with asthma and severe aspirin hypersensitivity were challenged on separate days with increasing doses of aspirin given by mouth, starting with 5 mg, until a reduction in FEV1 greater than 15% was obtained. Sodium cromoglycate in doses of 20-40 mg inhibited the bronchoconstrictive reaction not only when inhaled before the challenge but also after it, at a time when progressive red...
BACKGROUND There are no country-based data focused on aspirin (ASA)-exacerbated respiratory disease (AERD) in Turkey. OBJECTIVE To assess the prevalence of AERD in adult patients with asthma. METHODS A structured questionnaire was administered via face-to-face interview by a specialist in pulmonology/allergy at seven centres across Turkey. RESULTS A total of 1344 asthma patients (F/M: 108...
Background. Special regulatory role of eicosanoids has been postulated in aspirin-induced asthma. Objective. To investigate effects of aspirin on exhaled breath condensate (EBC) levels of eicosanoids in patients with asthma. Methods. We determined EBC eicosanoid concentrations using gas chromatography/mass spectrometry (GC-MS) and high-performance liquid chromatography/mass spectrometry (HPLC-M...
