    Abstract

    BACKGROUND: The prevalence and mean provocative dose of oral aspirin (MPDA) triggering respiratory reactions in people with asthma has been inconsistently reported, and the relationship between NSAID exacerbated respiratory disease (NERD) and asthma morbidity less well quantified. METHODS: A systematic review was performed identifying studies diagnosing NERD using blinded, placebo-controlled oral provocation challenge tests (OPCT) or by self-reported history in people with asthma. Data were extracted and effect estimates for changes in respiratory function, MPDA and asthma morbidity were pooled using random-effects meta-analysis. RESULTS: The prevalence of NERD in adults with asthma was 9.0% (95%CI 6-12%) using OPCTs and 9.9% (95%CI 9.4-10.5%) using self-reported history from questionnaires. The MPDA in adults with NERD was 85.8mg (95%CI 73.9-97.6). In people with NERD, risk of: uncontrolled asthma was increased two-fold (RR 1.96 (95% CI 1.25-3.07)); severe asthma and asthma attacks was increased by 60% (RR 1.58 (95% CI 1.15-2.16) and RR 1.59 (95% CI 1.21-2.09) respectively); emergency room visits was increased by 80% (RR 1.79 (95% CI 1.29-2.49)); and asthma hospitalisation was increased by 40% (RR 1.37 (95% CI 1.12-1.67)) compared to people with aspirin-tolerant asthma. CONCLUSIONS: Respiratory reactions triggered by oral aspirin in people with asthma are relatively common. At the population level, prevalence of NERD was similar when measured using appropriately conducted OPCTs or by self-reported history. On average respiratory reactions were triggered by clinically relevant doses of oral aspirin. Asthma morbidity was significantly increased in people with NERD who potentially require more intensive monitoring and follow-up. This article is protected by copyright. All rights reserved.
