摘要
目的:研究糖调节受损患者血清25(OH)D和免疫相关因子对亚临床动脉粥样硬化(AS)的影响。方法:选取2019年12月至2021年4月枣庄市立医院收治的142例糖调节受损患者,根据经颈动脉超声检查和臂踝脉搏波传导速度分组,仅糖调节受损患者为对照组(n=86),并发亚临床AS为观察组(n=56)。比较两组患者血清25(OH)D和免疫因子,应用颈动脉超声检测测定颈动脉内中膜厚度,Pearson法测定血清颈动脉内中膜厚度与血清25(OH)D和免疫因子的相关性。采集基线资料和血液学指标,单因素和多因素Logistic回归分析确定亚临床AS的影响因素,应用ROC曲线评估血清25(OH)D和免疫因子对亚临床AS的诊断效能。结果:观察组患者血清25(OH)D[(24.01±4.87)mmol/L vs 3(0.74±5.01)mmol/L,t=7.909,P=0.000)明显低于对照组,观察组患者TNF-α[(48.32±8.02)ng/L vs(33.21±9.00)ng/L,t=10.199,P=0.000)和IL-6[(41.22±9.43)ng/L vs(30.21±7.01)ng/L,t=7.492,P=0.000)明显高于对照组。颈动脉内中膜厚度与血清25(OH)D呈负相关(r=-0.428,P<0.001),颈动脉内中膜厚度与血清TNF-α和IL-6呈正相关(r=0.574,0.577,P<0.001)。Logistic回归分析结果表明,血清25(OH)D(OR=0.520,95%CI:0.401~0.675)、血清TNF-α(OR=1.667,95%CI:1.131~2.457)和血清IL-6(OR=1.478,95%CI:1.213~1.802)等是亚临床AS发生的影响因素。ROC曲线结果显示,血清25(OH)D最佳截断值为28.32 mmol/L,其对应的敏感度为69.64%,特异度为70.93%,AUC为0.803(95%CI:0.749~0.855);血清TNF-α临界值为40.56 ng/L,其对应的敏感度为71.43%,特异度为72.09%,AUC为0.761(95%CI:0.717~0.823);血清IL-6截断值为36.13 ng/L,其对应的敏感度为60.71%,特异度为60.47%,AUC为0.627(95%CI:0.566~0.702);回归分析对应的敏感度为85.71%,特异度为81.40%,AUC为0.889(95%CI:0.830~0.915)。结论:血清25(OH)D与免疫相关因子单独和联合回归检测可有效预测亚临床AS的发生,上述指标与颈动脉内中膜厚度相关,且血清25(OH)D和免疫相关因子是亚临床AS发生的预测指标,临床宜根据指标进行针对性干预,值得进一步研究。
Objective:To explore the correlation between abnormal expression of serum 25(OH)D and immune-related fac-tors and subclinical atherosclerosis(AS)in patients with impaired glucose regulation.Methods:A total of 142 patients with im-paired glucose regulation admitted to Zaozhuang Municipal Hospital from December 2019 to April 2021 were selected.The patients with impaired glucose regulation were selected as the control group(n=86)and patients with subclinical atherosclerosis were selected as the observation group(n=56)according to carotid ultrasound examination and bramolecular pulse wave conduction velocity.The serum 25(OH)D and immune factors were compared between the two groups.Carotid ultrasound was used to measure the carotid inti-media thickness,and Pearson method was used to determine the correlation between the intimedia thickness,25(OH)D and immune factors.Baseline data and hematological indicators were collected,univariate and multivariate Logistic regression analysis was per-formed to determine the influencing factors of subclinical atherosclerosis,and ROC curve was used to evaluate the diagnostic efficacy of serum 25(OH)D and immune factors in subclinical atherosclerosis.Results:The serum 25(OH)D[(24.01±4.87)mmol/L vs(30.74±5.01)mmol/L,t=7.909,P=0.000)in the observation group was significantly lower than that of control group.TNF-α[(48.32±8.02)ng/L vs(33.21±9.00)ng/L,t=10.199,P=0.000)and IL-6[(41.22±9.43)ng/L vs(30.21±7.01)ng/L,t=7.492,P=0.000)in ob-servation group were significantly higher than those in control group.Carotid intima-media thickness was negatively correlated with se-rum 25(OH)D(r=-0.428,P<0.001),and was positively correlated with serum TNF-αand IL-6(r=0.574,0.577,P<0.001).Logis-tic regression analysis showed that serum 25(OH)D(OR=0.520,95%CI:0.401~0.675),serum TNF-α(OR=1.667,95%CI:1.131~2.457)and serum IL-6(OR=1.478,95%CI:1.213~1.802)were the influencing factors of subclinical atherosclerosis.ROC curve showed that the optimal cut-off value of serum 25(OH)D was 28.32 mmol/L,and the corresponding sensitivity,specificity and AUC were 69.64%,70.93%and 0.803(95%CI:0.749~0.855),respectively.The critical value of serum TNF-αwas 40.56 ng/L,corre-sponding sensitivity was 71.43%,specificity was 72.09%,and AUC was 0.761(95%CI:0.717~0.823).Serum IL-6 cut-off value was 36.13 ng/L,corresponding sensitivity was 60.71%,specificity was 60.47%,and AUC was 0.627(95%CI:0.566~0.702).The sensitivity,specificity and AUC of regression analysis were 85.71%,81.40%and 0.889(95%CI:0.830~0.915).Conclusion:Serum 25(OH)D and immune-related factors alone and in combination can effectively predict the occurrence of subclinical atherosclerosis,which is correlated with carotid intima-media thickness,and serum 25(OH)D and immune-related factors are predictors of subclinical atherosclerosis.
