Résumé
Introduction: There are few data available regarding natural history of local allergic rhinitis (LAR). We previously reported the results of the first 5-years of follow-up observing a similar rate of development of systemic allergic rhinitis (AR) in both LAR patients and healthy controls. Objective: To explore the natural history of a population with LAR and the development of AR and comorbidities over a 10 year period. Methods: A cohort of 194 patients with LAR of recent onset (<18 months) and 130 age-and sex-matched healthy controls were prospectively evaluated in a 10-year follow-up study (2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016). All participants provided informed consent and ethic committee of the hospital approved the study. Clinical-demographic questionnaire, spirometry, SPT and specific IgE (sIgE) to aeroallergens were evaluated yearly. Nasal allergen provocation tests (NAPT) with D. pteronyssinus (DP), Alternaria, Olea europea, and grass pollen were performed at baseline, and after 5 and 10 years. Results: A total of 151 patients (78%) and 90 controls (69%) completed the study. At baseline, most patients had moderate-tosevere persistent-perennial rhinitis. Conjunctivitis (52%) and asthma (19%) were the main comorbidities, and DP the most frequent sensitizing aeroallergen (51.1%). During the 10 years of evaluation 21 new cases of asthma (12.5%, P = 0.007) and 17 new cases of conjunctivitis (10%, P = 0.067) were diagnosed. After 10 years of evolution a similar rate of development of AR was detected in patients and healthy controls (11.3 vs 10%, P = 0.761). In 5 patients, conversion to systemic atopy occurred in the last year of evaluation (3%). Conclusions: LAR is a well-differentiated clinical entity with a low rate of development of systemic atopy.
