摘要

目的分析慢性肾脏病（chronic kidney disease

CKD）患者血清Klotho蛋白水平与炎症因子的相关性，评价CKD患者Klotho与微炎症状态的关系。方法采用ELISA检测314例CKD 1～5期患者血清中Klotho蛋白、C反应蛋白（C-reaction protein，CRP）、白介素6（interleukin 6，IL-6）、肿瘤坏死因子α（tumor necrosis factor alpha，TNF-α）水平。生化检测血清白蛋白（albumin

ALB）、血磷(serum phosphorus，P)、血肌酐、尿酸（uric acid，UA）、胱抑素，记录患者年龄、性别、身高等指标，通过CKD-EPI公式估算肾小球滤过率（estimated glomerular filtration rate，eGFR）。单因素方差分析比较CKD不同分期血清中炎症因子水平，炎症因子与ALB、eGFR、UA、Klotho、P相关性采用等级相关（Spearman）分析，影响CKD患者炎症因子的因素采用多元线性回归分析。结果 ①单因素方差分析结果显示CKD 1～5期患者血清TNF-α含量逐渐升高（P0.05），CRP、IL-6差异无统计学意义(P0.05)，Klotho蛋白水平逐渐降低（P0.01）。②Spearman相关分析结果显示，CKD患者血清TNF-α水平与eGFR呈负相关（r=-0.550，P0.01）；CKD患者血清TNF-α与Klotho呈负相关（r=-0.753，P0.01）；Klotho与eGFR呈正相关（r=0.643，P0.01）。③多元线性回归分析结果显示，CKD患者血清TNF-α水平与Klotho、eGFR关系密切。结论 CKD患者随着eGFR的降低，血清Klotho水平逐渐下降，炎症因子TNF-α水平逐渐升高，两者之间具有明显的相关性，提示Klotho蛋白降低与CKD微炎症状态的发生和发展有着密切关联。

Abstract

Objective To analyze the correlation between serum Klotho protein level and inflammatory factors in the patients with chronic kidney disease (CKD) for assessment of Klotho protein associated microinflammatory state. Methods ELISA was used to measure the levels of serum Klotho protein

C-reactive protein (CRP)

interleukin-6 (IL-6) and tumor necrosis factor α (TNF-α) in 314 patients with stages 1~5 CKD. Serum albumin (ALB)

blood phosphorus (P)

serum creatinine (Scr)

uric acid (UA) and cystatin (Cys-c) were examined by bioanalysis. Patients’ age

sex

height

weight and other indicators were recorded. Estimated glomerular filtration rate (eGFR) was calculated according to CKD-EPI equation. The serum levels of inflammatory factors in different stages of CKD were compared by single factor analysis of variance (ANOVA).The correlation of inflammatory factors with ALB

eGFR

Klotho and P was analyzed by Spearman’s rank correlation. The parameters influencing the inflammatory factors in the CKD patients were analyzed by multiple linear regression analysis. Results ① ANOVA analysis showed that in the patients with stages 1~5 CKD

serum TNF-α was increased gradually (P0.01)

CRP and IL.6 had no significant difference; Klotho protein level was reduced along with the CKD stages (P0.01). ② Correlation analysis indicated that serum TNF-α levels in patients with CKD was negatively correlated with eGFR (r=-0.550，P0.01)and Klotho (r=-0.753，P0.01)

respectively

whereas Klotho protein and eGFR were positively correlated (r=0.643，P0.01) . ③ Multiple linear regression analysis demonstrated a strong relationship of serum TNF-α with both Klotho and eGFR in CKD patients. Conclusion Our data showed significantly decreased level of serum Klotho and increased level of inflammatory cytokine TNF.α in CKD patients with decreasing eGFR. The strong correlation between Klotho protein and inflammatory factors suggests that the decrease of Klotho protein is closely related to the occurrence and development of micro-inflammatory state in patients with CKD.
