Brief Summary

Through prospective exploration of the efficacy of intranasal corticosteroids (INCS) combined with intranasal antihistamines (INAH) and INCS combined with oral antihistamines (OAH) in treating moderate to severe allergic rhinitis symptoms, this study aims to provide evidence-based medical evidence for the standardized treatment of patients with moderate to severe allergic rhinitis accompanied by typical nasal and ocular symptoms.

Conditions

Allergic Rhinitis

Outcome Measures

Primary Outcomes (4)

• Total Nasal Symptom Score (TNSS)

  Description: The minimum possible scale value is 0, and the maximum possible scale value is 12. The higher scores mean a worse outcome.

  Before the start of treatment, on the 3rd, 7th, and 14th day of treatment

• Total Ocular Symptom Score (TOSS)

  The minimum possible scale value is 0, and the maximum possible scale value is 9. The higher scores mean a worse outcome.

  Before the start of treatment, on the 3rd, 7th, and 14th day of treatment

• Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ)

  The minimum possible scale value is 0, and the maximum possible scale value is 168. The higher scores mean a worse outcome.

  Before the start of treatment, on the 3rd, 7th, and 14th day of treatment

• General Health Status Score (SF36)

  The general health status score of patients is evaluated in nine dimensions: physiological function (PF), physiological function (RP), physical pain (BP), general health status (GH), energy (VT), social function (SF), emotional function (RE), mental health (MH), and health change (HT). Scores for each dimension range from 0 to 100, with higher scores indicating higher quality of life

  Before the start of treatment, on the 3rd, 7th, and 14th day of treatment

Secondary Outcomes (4)

• Endoscopic sinus scoring (Lund-Kennedy)

  Before the start of treatment, the 14th day of treatment

• blood cell count

  Before the start of treatment, the 14th day of treatment

• serum IgE level

  Before the start of treatment, the 14th day of treatment

• nasal secretions IgE level

  Before the start of treatment, the 14th day of treatment

Study Arms (2)

Intranasal corticosteroids (INCS) combined with oral antihistamines (OAH) used for treatment

EXPERIMENTAL

Intranasal corticosteroids (INCS) combined with nasal antihistamines (INAH) used for treatment. Azolastine and fluticasone nasal spray (Demins) were selected, and one spray (137 µ g Azolastine Hydrochloride and 50 µ g Fluticasone Propionate) was applied to each nostril twice a day for 14 consecutive days.
