Beneficial effect of nasal saline irrigation in children with allergic rhinitis and asthma: A randomized clinical trial
Abstract
BACKGROUND
Asthma and allergic rhinitis (AR) are chronic inflammatory diseases of airway and affect the disease severity each other.
OBJECTIVE
We performed this study to examine whether nasal saline irrigation (NSI) improves bronchial hyperresponsiveness and clinical parameters in children with asthma and allergic rhinitis (AR).
METHODS
We enrolled 20 children with AR and asthma aged between 6-18 years. Patients were randomized into two groups: irrigation group (8 boys and 2 girls) and control group (8 boys and 2 girls). The irrigation group performed daily NSI. All patients received 12-week treatment with montelukast, levocetirizine, and inhaled glucocorticoids. Provocative concentrations of methacholine causing a 20% decrease in FEV1 (PC20), Asthma Control Test (ACT), the Questionnaire for Quality-of-Life Specific to Allergic Rhinitis in Korean Children (QQOL-ARK) and exhaled nitric oxide (FENO) were compared before and after the study.
RESULTS
The PC20 at week 12 was higher than baseline measurements in the irrigation group (P = 0.017), while there was no difference in PC20 before and after treatment in the control group (P = 0.333). ACT score increased after 12 weeks of NSI (P = 0.007), while QQOL-ARK score decreased compared to baseline scores (P = 0.028) in the irrigation group. No differences in ACT and QQOL-ARK were found between weeks 0 and 12 in the control group. No differences were found in the median value of changes in PC20, ACT, QQOL-ARK and FENO between the…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 20 participants or records.
