Insights
Azithromycin prophylaxis significantly reduced recurrent acute rhinosinusitis (RARS) episodes in children with nonallergic rhinitis (NAR). This treatment improved nasal symptoms and decreased medication use over 12 months.
Area of Science:
- Pediatric Otolaryngology
- Clinical Immunology
- Pharmacology
Background:
- Recurrent acute rhinosinusitis (RARS) involves multiple, distinct episodes of acute rhinosinusitis with complete symptom resolution between occurrences.
- The efficacy of antibiotic prophylaxis for preventing RARS in children with nonallergic rhinitis (NAR) remains under-investigated.
Purpose of the Study:
- To investigate the preventive effect of azithromycin on RARS in pediatric patients diagnosed with NAR.
Main Methods:
- A randomized, double-blind, placebo-controlled trial was conducted involving children aged 5-15 years with RARS and NAR.
- Participants received either azithromycin (5 mg/kg/d, 3 days/week for 12 months) or a placebo.
- Outcomes measured included the number of rhinosinusitis episodes, nasal symptom severity via visual analog scale, and adjunctive medication use over 12 months.
Main Results:
- The azithromycin group showed a significant reduction in annual rhinosinusitis episodes from 5 to 0.5 (P < .001), compared to the placebo group.
- The number needed to treat with azithromycin to prevent one case of RARS was 2.
- Significant improvements were observed in nasal symptom scores (2.2 ± 1.4 vs 5.4 ± 1.8) and medication scores (3.9 ± 1.7 vs 5.4 ± 1.1) in the azithromycin group compared to baseline (P < .001).
Conclusions:
- Azithromycin prophylaxis is effective in reducing the frequency of rhinosinusitis episodes in children with NAR and RARS.
- The treatment also led to a significant decrease in medication requirements and an improvement in nasal symptoms.
Background:
Recurrent acute rhinosinusitis (RARS) is characterized by multiple episodes of acute rhinosinusitis between which symptoms and signs resolve completely. The role of antibiotic prophylaxis to prevent RARS in children with nonallergic rhinitis (NAR) has not been investigated.
Objective:
To evaluate the effect of azithromycin to prevent RARS in children with NAR.
Methods:
A randomized, double-blind, placebo-controlled study was conducted in NAR children (5-15 years) with RARS. Azithromycin (5 mg/kg/d) 3 d/wk for 12 months or placebo was assigned to the study group and the control group, respectively. Patients with allergic rhinitis were excluded. Number of rhinosinusitis episodes in 12 months, visual analog scale score of nasal symptoms, and adjunctive medication score were recorded.
Results:
Forty patients were enrolled and 20 patients were assigned randomly to the azithromycin and placebo groups. IgG subclass and specific antibody deficiencies were found in 83% and 2.5% of patients, respectively. After 12 months, the number of rhinosinusitis episodes/y in the azithromycin group reduced significantly from 5 to 0.5 (P < .001) in contrast to the placebo group. Number needed to treat using azithromycin prophylaxis to prevent 1 patient from having RARS was 2. The average visual analog scale score and the average adjunctive medication score in the azithromycin (but not in the placebo) group reduced significantly compared with baseline (2.2 ± 1.4 vs 5.4 ± 1.8) and (3.9 ± 1.7 vs 5.4 ± 1.1), respectively (P < .001).
Conclusions:
Azithromycin prophylaxis can reduce the number of rhinosinusitis episodes and medication score, and improve nasal symptoms in NAR children with RARS.

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
