PG - 673-679 LID - 10.17219/acem/135756 [doi] AB - BACKGROUND: Allergic rhinitis (AR) is a type I allergic reaction mediated by serum immunoglobulin E (IgE). OBJECTIVES: This study aimed to investigate the basophil activation rate and serum expression of inflammatory factors in AR patients and rats. The involvement of the IgE-FcepsilonRI-nuclear factor kappa B (NF-kappaB) signaling pathway in the pathogenesis of AR was also explored. MATERIAL AND METHODS: Thirty patients with pediatric AR (or asthma; untreated) were enrolled in our hospital as the observation group. Fifteen healthy children were selected as the control group. The basophil activation and serum levels of interleukin (IL)-4, IL-5, IL-13, IgE, and prostaglandin D2 (PGD2) in 2 groups of children were detected. Forty-eight male Sprague Dawley rats were randomly divided into group A (AR model group), group B (AR model + IgE inhibitor), group C (AR model + omalizumab), and group D (control). The animal model was established by intraperitoneal injection of ovalbumin and nasal mucosa stimulation. The basophil activation rate, serum levels of IL-4, IL-5, IL-13, IgE, and PGD2 were analyzed. RESULTS: In children with AR, the blood samples contained mainly activated basophils, whereas the healthy group showed mainly non-activated basophils. The levels of IL-4, IL-5, IL-13, IgE and PGD2 in the serum of the AR group were higher than those in healthy subjects (p < 0.05). In animal studies, the blood samples collected from group A were mainly activated basophils, while the samples of the other groups were mainly non-activated basophils. The serum contents of IL-4, IL-5, IL-13, IgE, and PGD2 in group A were significantly higher than those in groups B and C (p < 0.05). CONCLUSIONS: Patients with AR showed increased activation of basophils and elevated expression of IL-4, IL-5, IL-13, IgE, and PGD2. The upregulation of FcepsilonRI and NF-kappaB was involved in the pathogenesis of AR.
