Expression of cysteinyl leukotriene receptor 1 in adenoid tissue of children with adenoid hypertrophy and its influencing factors

Abstract

Objective To investigate the expression characteristics of cysteamine leukotriene receptor 1 (CysLTR1) in the adenoid tissue of children with adenoid hypertrophy (AH), as well as the mechanism of action of CysLTR1 in the formation of AH and the influencing factors for CysLTR1 expression. Methods A total of 71 children who underwent adenoidectomy in Department of Otolaryngology, Weihai Municipal Hospital, from October 1, 2020 to October 1, 2021 were enrolled. Immunohistochemical staining was performed for CysLTR1 in the resected specimens, and according to the results of staining, the children were divided into high CysLTR1 expression group and low CysLTR1 expression group. The two groups were compared in terms of the data including sex, age, degree of adenoid hypertrophy, presence or absence of allergic rhinitis, and presence or absence of other comorbidities (secretory otitis media, chronic sinusitis, and sleep apnea syndrome), and a multivariate logistic regression analysis was used to identify the influencing factors for the expression of CysLTR1 in children with AH. Results Immunohistochemistry showed that CysLTR1 was expressed in the adenoid tissue of all 71 children with AH, and there were significant differences between the high and low expression groups in the degree of adenoid hypertrophy, the presence or absence of allergic rhinitis, and the presence or absence of other comorbidities (χ2=9.003-49.196,P<0.05). The logistic regression analysis showed that the severe of adenoid hypertrophy, the presence of allergic rhinitis, and the presence of other comorbidities were independent risk factors for the expression of CysLTR1 in children with AH (P<0.05). Conclusion The expression of CysLTR1 in adenoid tissue of children with AH is associated with the degree of adenoid hypertrophy, the presence or absence of allergic rhinitis, and the presence or absence of other comorbidities, and these three indices are independent risk factors for the high expression of CysLTR1.
