BACKGROUND Advanced glycation end products (AGEs) in the plasma are associated with a number of age-related diseases that possibly lead to reduced longevity. However, previous studies showed large inconsistencies in the association between AGEs or their soluble receptor (sRAGE) and mortality. We studied this association in a cohort study of general population and assessed the potential changes in this association over time. METHODS We used data of 958 men and 802 women from the general population in Halle, Germany with a follow up of 12 years. The associations were assessed by means of Kaplan-Meyer survival curves and multivariable and time-varying Cox-regression. RESULTS AGEs and sRAGE were either not or only weakly (and in the other direction than expected) associated with all-cause mortality after 12 years follow-up in men and women (AGEs: Hazard ratio (HR) = 0.93, 95% confidence interval (95%CI) = 0.83-1.05 for men; HR = 0.88, 95%CI = 0.74-1.05 for women; sRAGE: HR = 1.08, 95%CI = 0.95-1.23 for men; HR = 1.10, 95%CI = 0.92-1.30 for women). There was no change of the predictive values over the follow up time. Sub-analyses with participants with and without AGEs-related conditions (diabetes mellitus and decreased renal function), with age stratified groups (younger (<65 years) and older (≥65 years) participants), with cardiovascular disease mortality as the outcome and the AGE/sRAGE ratio as predictor provided similar results. CONCLUSIONS Our findings suggest a lack of the expected association with mortality and contribute to the inconsistent findings for plasma-measured AGEs, sRAGE, and AGE/sRAGE ratio.

晚期糖基化终产物,其可溶性受体与普通人群的死亡率之间的关联:CARLA研究的结果。

背景技术血浆中晚期糖基化终产物(AGEs)与许多与年龄有关的疾病有关,这些疾病可能导致寿命降低。但是,以前的研究表明,AGEs或其可溶性受体(sRAGE)与死亡率之间的关联存在很大的不一致。我们在一项针对一般人群的队列研究中研究了这种关联,并评估了这种关联随时间的潜在变化。方法我们采用了德国哈雷地区958名男性和802名女性的数据,并进行了12年的随访。通过Kaplan-Meyer生存曲线和多变量且随时间变化的Cox回归来评估相关性。结果男性和女性随访12年后,年龄和sRAGE与全因死亡率无关(或仅弱于(与预期相反))(AGEs:男性的危险比(HR)= 0.93,95%置信区间(95%CI)= 0.83-1.05;女性HR = 0.88,95%CI = 0.74-1.05;sRAGE:男性HR = 1.08,95%CI = 0.95-1.23;HR = 1.10,女性95%CI = 0.92-1.30)。在随访期间,预测值没有变化。对患有和不伴有AGEs相关疾病(糖尿病和肾功能下降),年龄分层组(年龄较小(<65岁)和年龄较大(≥65岁)的参与者,以心血管疾病死亡率和结果的参与者进行的亚分析AGE / sRAGE比作为预测因子提供了相似的结果。结论我们的发现提示缺乏与死亡率的预期关联,并导致血浆测量的AGEs,sRAGE和AGE / sRAGE比值不一致。女性HR = 0.88,95%CI = 0.74-1.05;sRAGE:男性HR = 1.08,95%CI = 0.95-1.23;HR = 1.10,女性95%CI = 0.92-1.30)。在随访期间,预测值没有变化。对患有和不伴有AGEs相关疾病(糖尿病和肾功能下降),年龄分层组(年龄较小(<65岁)和年龄较大(≥65岁)的参与者,以心血管疾病死亡率为结果和AGE / sRAGE比作为预测因子提供了相似的结果。结论我们的发现提示缺乏与死亡率的预期关联,并导致血浆测量的AGEs,sRAGE和AGE / sRAGE比值不一致。女性HR = 0.88,95%CI = 0.74-1.05;sRAGE:男性HR = 1.08,95%CI = 0.95-1.23;HR = 1.10,女性95%CI = 0.92-1.30)。在随访期间,预测值没有变化。对患有和不伴有AGEs相关疾病(糖尿病和肾功能下降),年龄分层组(年龄较小(<65岁)和年龄较大(≥65岁)的参与者,以心血管疾病死亡率和结果的参与者进行的亚分析AGE / sRAGE比作为预测因子提供了相似的结果。结论我们的发现提示缺乏与死亡率的预期关联,并导致血浆测量的AGEs,sRAGE和AGE / sRAGE比值不一致。在随访期间,预测值没有变化。对患有和不伴有AGEs相关疾病(糖尿病和肾功能下降),年龄分层组(年龄较小(<65岁)和年龄较大(≥65岁)的参与者,以心血管疾病死亡率和结果的参与者进行的亚分析AGE / sRAGE比作为预测因子提供了相似的结果。结论我们的发现提示缺乏与死亡率的预期关联,并导致血浆测量的AGEs,sRAGE和AGE / sRAGE比值不一致。在随访期间,预测值没有变化。对患有和不伴有AGEs相关疾病(糖尿病和肾功能下降),年龄分层组(年龄较小(<65岁)和年龄较大(≥65岁)的参与者,以心血管疾病死亡率为结果和AGE / sRAGE比作为预测因子提供了相似的结果。结论我们的发现提示缺乏与死亡率的预期关联,并导致血浆测量的AGEs,sRAGE和AGE / sRAGE比值不一致。以心血管疾病死亡率作为结果,而AGE / sRAGE比作为预测因子则提供了相似的结果。结论我们的发现提示缺乏与死亡率的预期关联,并导致血浆测量的AGEs,sRAGE和AGE / sRAGE比值不一致。以心血管疾病死亡率作为结果,而AGE / sRAGE比作为预测因子则提供了相似的结果。结论我们的发现提示缺乏与死亡率的预期关联,并导致血浆测量的AGEs,sRAGE和AGE / sRAGE比值不一致。
