Background:
Symptom control in patients with moderate-to-severe persistent allergic rhinitis (PAR) who remain inadequately controlled on intranasal corticosteroid monotherapy remains challenging, highlighting the urgent need for more effective treatments. This study aimed to determine whether the addition of nasal saline irrigation to a regimen of intranasal corticosteroids and antihistamines can further improve symptoms in patients with moderate-to-severe PAR.
Methods:
A multicenter, randomized, open-label, controlled trial was conducted, enrolling 248 eligible patients aged 12 years and above from six clinical centers. They were randomized 1:1 into two groups. The experimental group received nasal saline irrigation combined with azelastine-fluticasone (Aze-Flu) nasal spray, and the control group was treated with azelastine nasal spray and fluticasone nasal spray. The primary outcome was the least-squares-mean (LSmean) change in total nasal symptom score (TNSS) from baseline to four weeks, with secondary outcomes including LSmean change in TNSS from baseline to two weeks, subscores, rhinoscopic scores, visual analogue scale (VAS), and rhinoconjunctivitis quality of life questionnaire (RQLQ) scores.
Results:
Both groups exhibited significant reductions in TNSSs from baseline (p < 0.001). In comparison to the control group, the experimental group exhibited greater LSmean changes in TNSS scores following either two or four weeks of treatment (p < 0.001 at both time points). The experimental group presented more favorable changes in rhinoscopy scores, VAS scores, and RQLQ scores. Both groups showed no substantial differences in adverse events, indicating a comparable safety profile.
Conclusion:
Nasal saline irrigation combined with Aze-Flu nasal spray provides additional benefits in managing moderate-to-severe PAR, with good safety and tolerability. This combination therapy could be a valuable option in primary care settings.

01:25Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
