BACKGROUND The release of cyclooxygenase-2 (COX-2) and lipoxin A4 (LXA4) from blood mononuclear cells in patients with aspirin-exacerbated respiratory disease (AERD) is only partially understood. OBJECTIVE To investigate the presence of COX-2 and LXA4 in peripheral blood mononuclear cells (PBMC) derived from patients with AERD and with nasal polyps (NP) (designated as the AERD-NP group), pati...

Aspirin-exacerbated respiratory disease (AERD) remains widely underdiagnosed in asthmatics, primarily due to insufficient awareness of the relationship between aspirin ingestion and asthma exacerbation. The identification of aspirin hypersensitivity is therefore essential to avoid serious aspirin complications. The goal of the study was to develop plasma biomarkers to predict AERD. We identifie...

Aspirin-exacerbated respiratory disease (AERD) is a clinical syndrome that is characterized by nasal polyposis, general symptoms of asthma and sensitive response to non-steroidal anti-inflammatory drugs (NSAIDs). Although the exact function of tripartite motif-containing 26 (TRIM26) still remains unknown, the gene functions in the immune response....

Aspirin intolerant asthma (AIA) is frequently characterized as an aspirin (ASA)-exacerbated respiratory disease (AERD). It is a clinical syndrome associated with chronic severe inflammation in the upper and lower airways resulting in chronic rhinitis, sinusitis, recurrent polyposis, and asthma. AERD generally develops secondary to abnormalities in inflammatory mediators and arachidonic acid bio...

PURPOSE Aspirin exacerbated respiratory disease (AERD) results in a severe asthma attack after aspirin ingestion in asthmatics. The filamin A interacting protein 1 (FILIP1) may play a crucial role in AERD pathogenesis by mediating T cell activation and membrane rearrangement. We investigated the association of FILIP1 variations with AERD and the fall rate of forced expiratory volume in one seco...

PURPOSE Although the mechanism of virus-induced, aspirin-exacerbated respiratory disease (AERD) is not known fully, direct activation of viral components through Toll-like receptor 3 (TLR3) has been suggested. TLR3 recognizes double-stranded RNA (dsRNA), and activates nuclear factor-κB and increases interferon-γ, which signals other cells to induce airway inflammation in asthma. Considering the...

BACKGROUND Although the prevalence of aspirin-exacerbated respiratory disease (AERD) in western populations is high, AERD is rather rare in China, and few related studies have been published to date. METHODS We performed a prospective cohort investigation on the incidence of AERD in patients with chronic rhinosinusitis (CRS) in southern China. A literature search of the China Academic Journa...

It is well known that aspirin-exacerbated respiratory disease (AERD) is more common in women than in men, however, whether gene polymorphisms of the thromboxane A2 receptor (TBXA2R) and chemoattractant receptor-homologous molecules expressed on Th2 cells (CRTH2) are associated with the susceptibility of AERD remains unknown. In this study, we examined the gene polymorphisms in a Japanese popula...

BACKGROUND Aspirin-exacerbated respiratory disease (AERD) refers to the development of bronchoconstriction in asthmatics following the ingestion of aspirin. Although alterations in eicosanoid metabolites play a role in AERD, other immune or inflammatory mechanisms may be involved. We aimed to identify proteins that were differentially expressed in nasal polyps between patients with AERD and asp...

BACKGROUND Aspirin desensitization is an effective therapy for moderate-to-severe aspirin-exacerbated respiratory disease (AERD). Desensitization also allows the use of aspirin for secondary cardiovascular prevention. OBJECTIVE We sought to investigate the cost-effectiveness of aspirin desensitization with subsequent aspirin therapy in patients with AERD. METHODS The Healthcare Cost and Uti...
