Abstract
Objectives: Nasal polyposis (NP) is a common and recurrent condition of the sinonasal cavity which has significant impact on patients' quality of life. NP pathophysiology involves a complex interplay of genetic, environmental, and immunological factors. Several studies have explored the association between human leukocyte antigen (HLA) class II alleles and NP, but the results have been conflicting. The aim of this meta-analysis is to investigate the association between HLA class II alleles, specifically HLA-DQA1, HLA-DQB1, and HLA-DRB1and NP risk.
Methods: A systematic review was conducted using electronic databases, including PubMed, Google Scholar, and Cochrane Library, to identify studies investigating the association between HLA class II alleles and NP. Eligible studies were identified by specific inclusion and exclusion criteria. The odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the association between HLA class II alleles and NP risk. A random-effects model was used to calculate the pooled OR and corresponding 95% CI, and a study required a heterogeneity assessment value I2 < 25% to be considered for analysis.
Study design: Meta-analysis.
Results: A total of four studies were included in this meta-analysis, involving a total of 258 NP alleles and 802 control alleles. The analysis indicated that DQA1*0201 (OR = 3.08, 95% CI [1.70, 5.59]) and DRB1*7 (OR = 2.04, 95% CI [1.14, 3.66]) were significantly associated with increased risk of NP. The analysis of the NP risk alleles DQA1*0201 and DRB1*7 had an I2 < 0% representing low heterogeneity. Sensitivity analysis with LFK indices showed minor asymmetry in either allele.
Conclusions: This meta-analysis provides evidence that the HLA-DQA1*0201 and HLA-DRB1*7 alleles are risk factors for the development of NP. These findings could contribute to a better understanding of the genetic predisposition of NP and may have implications for the development of novel approaches for the prevention and treatment of this condition.
期刊介绍：
The Annals of Otology, Rhinology & Laryngology publishes original manuscripts of clinical and research importance in otolaryngology–head and neck medicine and surgery, otology, neurotology, bronchoesophagology, laryngology, rhinology, head and neck oncology and surgery, plastic and reconstructive surgery, pediatric otolaryngology, audiology, and speech pathology. In-depth studies (supplements), papers of historical interest, and reviews of computer software and applications in otolaryngology are also published, as well as imaging, pathology, and clinicopathology studies, book reviews, and letters to the editor. AOR is the official journal of the American Broncho-Esophagological Association.
