Abstract

BACKGROUND: Nasal irrigations (NI) are increasingly used as an over-the-counter adjunctive treatment for allergic rhinitis (AR), but clinical studies on their effectiveness are limited.

METHODS: An open-label, controlled, non-randomized, real-life study was conducted to evaluate the effectiveness of NI with a new hypertonic solution as add-on treatment for AR. Children and adolescents with AR were prescribed symptomatic treatment. The active group also received an additional sea-water NI solution supplemented with algae extracts. The primary endpoint was symptom control, assessed by the control of allergic rhinitis and asthma test (CARAT) questionnaires. Moreover, the MASK/Allergy Diary was used to track symptoms and daily medication use that were combined in a novel total symptom/medication score (TSMS).

RESULTS: We assessed 76 patients. Overall, there was a significant improvement of CARAT results (median Z-score change of 1.1 in the active/NI group vs. 0.4 in the control group;

CONCLUSION: Addition of NI with a sea-water solution to regular treatment improved AR symptom control. CARAT questionnaires and MASK application can be useful outcome tools in real-life studies.
