Short-Term Nasal Decongestant as Bridge Therapy Combined With Intranasal Corticosteroids in Children With Persistent Allergic Rhinitis: A Randomized Controlled Trial

Allergic rhinitis is one of the most common chronic inflammatory diseases in childhood and significantly affects sleep quality, school performance, daily functioning, and quality of life. Intranasal corticosteroids (INS) are recommended as first-line therapy because of their strong anti-inflammatory effects. However, the onset of symptom relief may take several days or weeks, especially in patients with severe nasal congestion. This delayed onset may negatively affect treatment adherence and early treatment satisfaction.

Short-term use of topical nasal decongestants may provide rapid nasal patency and facilitate delivery of intranasal corticosteroids into the nasal cavity. This study investigates whether short-term oxymetazoline therapy added to the initiation of INS treatment can function as a "bridge therapy" in children with persistent allergic rhinitis.

This prospective randomized controlled study enrolled children aged 4-18 years diagnosed with moderate-to-severe persistent allergic rhinitis according to ARIA guidelines. Participants were randomized into two parallel treatment groups:

1. Intranasal corticosteroid monotherapy group (mometasone furoate for 4 weeks)
2. Combination therapy group (mometasone furoate for 4 weeks plus oxymetazoline during the first 5 days)

Clinical symptom severity was assessed using Total Nasal Symptom Score (TNSS). Objective nasal airflow was evaluated with Peak Nasal Inspiratory Flow (PNIF). Nasal inflammation was assessed using Nasal Nitric Oxide (nNO). Disease-specific quality of life was measured using the Pediatric Rhinoconjunctivitis Quality of Life Questionnaire (PRQLQ), and treatment adherence was evaluated using the Medication Adherence Rating Scale (MARS).
