摘要: 摘要:目的 探讨成年人群中血清补体 C3 水平是否与前期糖尿病的患病率和发生率有关。方法 对象来源于天津医科大学总医院健康管理中心的健康体检成年人群。针对研究对象分别进行横断面 (n=10 539) 和前瞻性队列研究 (n=3 064)。队列研究平均随访时间为 2.8 年, 最长达 6 年。在基线和每个随访年收集的相关资料包括: 血清 C3 水平、 空腹血糖和其他潜在混杂因素。前期糖尿病的诊断依据美国糖尿病协会标准。采用多元 Logistic 回归和 Cox 比例风险回归模型评估 C3 五分位与前期糖尿病的关系。结果 前期糖尿病的患病率是 19.9%, 发生率是 99.5/ 1 000 人·年。在横截面分析中, 调整了潜在混杂因素后, 与最低 C3 五分位组相比, 第 2~5 C3 五分位数前期糖尿病的比值比 (OR 及 95%CI) 分别为 1.18 (0.98~1.42)、 1.11 (0.92~1.34)、 1.38 (1.15~1.65)、 1.63 (1.36~1.95)。在队列研究中, 与最低 C3 五分位数相比, 经多变量调整后, 第 2~5 C3 五分位数的高血压发病风险比 (RR 及 95%CI) 分别为 1.20(0.94~1.54)、 1.48 (1.16~1.88)、 1.38 (1.09~1.76) 和 1.53 (1.21~1.95)。结论 在成年人中, 血清 C3 水平与前期糖尿病的患病率和发生率密切相关。C3 作为生物学标志物, 可能对前期糖尿病和糖尿病的早期预防有价值。

Abstract: Abstract: Objective To evaluate whether serum complement C3 concentration was associated with the prevalence and incidence of prediabetes in an adult population. Methods A cross-sectional (n=10 539) and prospective cohort (n= 3 064, followed up for -6 years, mean: 2.8 y) study was performed on subjects recruited from the Health Management Center of Tianjin Medical University General Hospital in Tianjin. Measurements of serum C3 concentration, blood fasting glucose and other potential confounding factors were assessed at baseline and per year during the follow-up period. Prediabetes was defined according to the criteria of American Diabetes Association. Adjusted Logistic and Cox proportional hazards regression models were used to assess the associations between C3 quintiles and prediabetes. Results The prevalence and incidence of prediabetes were 19.9% and 99.5 per 1 000 person- year, respectively. In cross- sectional analysis, after adjusted for potential confounders, the odds ratios (95% confidence interval) of prediabetes for increasing quintiles of C3 were 1.00 (reference), 1.18 (0.98-1.42), 1.11 (0.92-1.34), 1.38 (1.15-1.65) and 1.63 (1.36-1.95) (P for trend <0.000 1). In cohort analysis, in the final multivariate models, the hazard ratios (95% confidence interval) for prediabetes across C3 quintiles were 1.00 (reference), 1.20 (0.94-1.54), 1.48 (1.16-1.88), 1.38 (1.09-1.76) and 1.53 (1.21-1.95) (P for trend < 0.001), respectively. Conclusion The study suggests that the elevated C3 level is significantly associated with the prevalence and incidence of prediabetes, which means that C3 can be used as a biomarker in early prevention of prediabetes and diabetes.
