Design outcomes

Primary

MeasureTime frame
Efficacy of a quail egg homogenate-based dietary supplement as adjunctive therapy in patients with seasonal allergic rhinitis assessed by the mean change (pre-treatment / post-treatment) in Total Symptoms Score (TSS) which included four parameters related to symptoms (rhinorrhea, nasal congestion, nasal itching, sneezing). The intensity was calculated by total and individual nasal symptoms score using a numerical score scale (0 – no symptoms, 3 – severe) Timepoint: Baseline to week 4 inclusive

Secondary

MeasureTime frame
Change in Rhinitis Control Assessment Test (RCAT). A self-administered instrument for evaluating symptom control in patients with rhinitis. 5-point Likert scale ("never" to "extremely often"), scores range from 6 to 30, with scores < 21 indicating bad rhinitis symptom control. Timepoint: Baseline to week 4 inclusive. - Total Nasal airflow resistance (right+left) (Pa/cm3/s), using an active anterior rhinomanometry. It reflects the resistance of both sides of the nasal cavity. Normal values range is 0.10-0.40 Pa/cm3/s. Timepoint: Baseline to week 4 inclusive. - Total plasma IgE (IU/mL). Timepoint: Baseline to week 4 inclusive. - Rescue medication use (cetirizine 5 mg, once daily). Timepoint: week 4. - Adverse events. Timepoint: week 4.
