Resumo Objective: Our objective was to evaluate the action of topical nasal steroid in nasal congestion and nasal hyper-reactivity in children and adolescents with persistent allergic rhinitis.Methods: Twenty atopic children and adolescents (6 to 18 years) with moderate-to-severe persistent allergic rhinitis (PAR) were treated with mometasone furoate (100 mu g once a day) for 21 days. At the beginning and end of treatment, the following were recorded: a) nasal symptoms score; b) several parameters of nasal congestion measured by acoustic rhinometry (SRE 2000 Rhinometrics); c) degree of nasal hyper-reactivity to histamine (concentration of histamine necessary to induce at least 100% increase in total nasal resistance during nasal provocation test). Data were compared with those from 20 controls.Results: Compared to controls, PAR patients had significantly higher score of symptoms, as well as higher degree of nasal hyper-reactivity and lower nasal volumes. After treatment, there was a significant decrease in the mean nasal symptoms score (8.0 versus 3.8; p < 0.001) and in the nasal hyper-reactivity (histamine concentration: 0.72 mg/ml versus 2.60 mg/ml; p < 0.001). Congestion improvement was observed by the increase in all acoustic rhinometry parameters. Among all studied volumes, the volume in the segment between 2 and 5 cm showed the highest mean increase (19.8%).Conclusion: Treatment with topical nasal steroid objectively reduced nasal congestion and nasal histamine hyper-reactivity in children and adolescents with PAR.
