Allergic Rhinitis
Conditions
Brief summary
Single-center, randomized, placebo-controlled study to: * characterize the subjects at baseline and discriminate groups of children based on IL-5, IL-17, IL-23 and INF-γ; * investigate the effect of Resveratrol plus Carboxymethyl-β-Glucan, two sprays (100µL/spray) for nostril three times/day for 4 weeks, in comparison with placebo, in reducing nasal interleukin-5 (IL-5) in children with Allergic Rhinitis (AR). Secondary objectives are to examine the effect of resveratrol plus carboxymethyl-β-glucan, in comparison with placebo, on subjective parameters, i.e. symptom scores, visual analogue scales for rhinitis, quality of life and quality of sleep, and the effect on objective parameters, i.e. nasal nitric oxide (nNO) levels, nasal cytology and acoustic rhinometry.
Interventions
Patients in this arm will receive Resveratrol plus Carboxymethyl-β-Glucan, two sprays (100µL/spray) per nostril three times/day for 4 weeks
Patients in this arm will receive nasal saline solution 0.9%, two sprays per nostril, three times/day for 4 weeks
