Rhinitis phenotypes and multimorbidities in the general population: the CONSTANCES cohort

Résumé

BACKGROUND: Scarce epidemiological studies have characterised allergic rhinitis (AR) and non-allergic rhinitis (NAR) in adults. AIMS: In a population-based cohort, to (1) describe rhinitis, AR and NAR, and (2) explore how asthma and conjunctivitis may lead to the identification of novel rhinitis phenotypes. METHODS: In this cross-sectional analysis, current rhinitis was defined in the last 12 months using questionnaire from the French Constances cohort. Participants with current rhinitis reporting nasal allergies were considered as AR, otherwise as NAR. We described AR and NAR phenotypes, and their phenotypes including co-occurrence with ever-asthma and ever-conjunctivitis. RESULTS: Among the 20 772 participants included in this analysis (55.2% women, mean age: 53±13 years), crude prevalences of AR and NAR were 28.0% and 10.9%. AR participants reported more frequently persistent rhinitis (31.6% versus 25.1%), and moderate to severe rhinitis (40.1% versus 24.2%) than NAR participants. Among AR or NAR participants, those with ever-asthma reported more moderate-severe rhinitis. Participants with AR, ever-asthma, and ever-conjunctivitis had an earlier age of rhinitis onset, more severe rhinitis, and higher eosinophil counts than participants in other groups. Results were replicated in another cohort. CONCLUSIONS: In this large population-based cohort, 40% reported current rhinitis, with a lower prevalence of moderate-severe rhinitis than in clinical practice. For the first time in a general adult population, we showed that AR and NAR alone or in combination with asthma or in combination with asthma and conjunctivitis are different phenotypes. These results provide new insights on how best to manage rhinitis and its multimorbidities.
