BACKGROUND: Aspirin-exacerbated respiratory disease (AERD) comprises the triad of
chronic rhinosinusitis with nasal polyps (CRSwNP), asthma, and intolerance to
inhibitors of the cyclooxygenase-1 (COX-1) enzyme. The prevalence of AERD remains
unclear, and few studies have compared the clinical characteristics of patients
with AERD to those with CRSwNP alone, asthma alone, or both CRSwNP and asthma.
OBJECTIVE: To determine the prevalence of AERD within a tertiary care setting,
and to identify unique clinical features that could distinguish these patients
from those with both CRSwNP and asthma or with CRSwNP alone. METHODS: Electronic
medical records of patients at Northwestern in Chicago, Illinois, were searched
by computer algorithm and then manual chart review to identify 459 patients with
CRSwNP alone, 412 with both CRSwNP and asthma, 171 with AERD, and 300 with asthma
only. Demographic and clinical features including sex, atopy, and sinus disease
severity were characterized. RESULTS: The prevalence of AERD among patients with
CRSwNP was 16%. Patients with AERD had undergone 2-fold more sinus surgeries (P <
.001) and were significantly younger at the time of their first surgery (40 ± 13
years) than were patients with CRSwNP (43 ± 14 years; P < .05). Atopy was
significantly more prevalent in patients with AERD (84%) or asthma (85%) than in
patients with CRSwNP (66%, P < .05). More patients with AERD (13%) had
corticosteroid-dependent disease than patients with both CRSwNP and asthma (4%, P
< .01) or asthma (1%, P < .001). CONCLUSIONS: AERD is common among patients with
CRSwNP; even though patients with AERD have CRSwNP and asthma, the clinical
course of their disease is not the same as of patients who have CRSwNP and asthma
but are tolerant to COX-1 inhibitors.
