龈沟液中sICAM-1、IL-1β和HIF-1α水平与义齿种植修复并发种植体周围炎的关系

目的 ：探讨龈沟液中可溶性细胞间黏附分子1(sICAM-1)、白细胞介素1β(IL-1β)和缺氧诱导因子1α(HIF-1α)水平与义齿种植修复并发种植体周围炎（PI）的关系。方法 ：选择2019年1月—2021年12月奉城医院收治的198例义齿种植修复患者，根据义齿种植修复3个月后是否并发PI将患者分为PI组和非PI组。采用酶联免疫吸附法检测义齿种植修复前龈沟液中sICAM-1、IL-1β和HIF-1α水平。多因素Logistic回归分析并发PI的影响因素，ROC曲线分析龈沟液中sICAM-1、IL-1β和HIF-1α水平对义齿种植修复并发PI的预测价值。采用SPSS 28.0软件包对数据进行统计学处理。结果：义齿种植修复后3个月，198例患者PI发生率为17.68%(35/198)。PI组龈沟液中sICAM-1、IL-1β和HIF-1α水平显著高于非PI组（P<0.05）。多因素Logistic回归分析显示，sICAM-1(OR=1.135,95%CI:1.066～1.208)、IL-1β(OR=1.106,95%CI:1.054～1.161)和HIF-1α(OR=1.008,...

Relationship between sICAM-1, IL-1β and HIF-1α levels in gingival sulcus fluid and peri-implantitis in patients with implant restoration

PURPOSE: To investigate the relationship between the levels of soluble intercellular adhesion molecule-1 (sICAM-1), interleukin-1β (IL-1β) and hypoxia-inducible factor-1α (HIF-1α) in gingival sulcus fluid and peri-implantitis (PI) in patients with implant restoration. METHODS: A total of 198 patients with implant restoration admitted to Fengcheng Hospital from January 2019 to December 2021 were selected, the patients were divided into PI and non-PI group according to whether the implant restoration was complicated by PI 3 months after restoration. The levels of sICAM-1, IL-1β and HIF-1α in the gingival sulcus fluid prior to implant restoration were measured by enzyme-linked immunosorbent assay. Multi-factor logistic regression was used to analyze the factors influencing concurrent PI in patients with implant restoration. ROC curves were used to analyze the predictive value of sICAM-1, IL-1β and HIF-1α levels in gingival sulcus fluid on concurrent PI in patients with implant restoration. SPSS 28.0 software package was used for statistical processing of the data. RESULTS: The incidence of PI in 198 patients with implant restoration was 17.68% (35/198) 3 months after implant restoration. The levels of sICAM-1, IL-1β and HIF-1α in the gingival sulcus fluid were significantly higher in the PI group than in the non-PI group (P<0.05). Multi-factor logistic regression analysis showed that elevated sICAM-1(OR=1.135, 95%CI: 1.066 to 1.208), IL-1β (OR=1.106, 95%CI: 1.054 to 1.161) and HIF-1α (OR=1.008, 95%CI: 1.004 to 1.012) were independent risk factors for complications of PI in prosthetic patients(P<0.05). ROC curve analysis showed that the area under the curve for sICAM-1, IL-1β and HIF-1α levels in gingival sulcus fluid alone and in combination for the diagnosis of concurrent PI in patients with implantation was 0.787, 0.785, 0.794 and 0.930, respectively, with sensitivity of 80.00%, 74.29%, 62.86% and 88.57% and specificity of 66.87%, 74.85%, 78.53% and 85.28%, respectively. CONCLUSIONS: Elevated levels of sICAM-1, IL-1β and HIF-1α in gingival sulcus fluid are independent risk factors for PI complications in patients with implant restoration and can be used as an auxiliary predictor of PI complications in patients with implant restoration.
