摘要
目的观察慢性肾功能不全对血清异常凝血酶原（PIVKA-Ⅱ）和唾液酸（SA）水平的影响。方法用化学发光法和酶法分别检测127例慢性肾功能不全、32例肾功能正常肾脏疾病患者、57例体检健康者和120例肝细胞癌（HCC）患者血清PIVKA-Ⅱ和SA水平。分别测定上述受试者血清尿素（Urea）和肌酐（Cr）水平,并估算肾小球滤过率值（eGFR）。结果健康对照组、肾功能正常疾病组和肾功能不全疾病组三组间血清PIVKA-Ⅱ水平没有统计学差异（H=2.902,P〉0.05）,且明显低于HCC组（U值分别为319.50、203.00、665.50,P均〈0.001）。肾功能不全疾病组中各期之间血清PIVKA-Ⅱ水平也没有统计学差异（H=3.991,P〉0.05）。血清SA水平在健康对照组、肾功能正常疾病组和肾功能不全疾病组之间（H=63.685,P〈0.001）,以及在肾功能不全疾病组各期之间（H=64.689,P〈0.001）均有统计学差异。血清SA水平与eGFR呈负相关（r=-0.705,P〈0.001）,与Urea、Cr水平呈正相关（r=0.599、0.704,P〈0.001）。HCC组血清SA水平较CKD1～4期均明显升高（U值分别为126.00、163.50、247.00、715.00,P均〈0.001）,较CKD5期无明显变化（U=419.00,P〉0.05）。结论肾功能不全对血清PIVKA-Ⅱ表达无明显影响,但可明显提高血清SA的表达水平,并与肾功能损害程度密切相关。可见血清SA水平升高不仅对HCC及其他多种恶性肿瘤有辅助诊断价值,还可较好地反映慢性肾功能不全患者的肾功能状态。
Objective To investigate the impact of chronic renal insufficiency on serum levels of protein induced by vitamin K absence or antagonist-Ⅱ（PIVKA-Ⅱ）and sialic acid（SA）.MethodsThe levels of serum PIVKA-Ⅱ,SA,urea and creatinine（Cr）were detected in 127 cases of chronic renal insufficiency,32 cases of renal disease with normal renal function,57 healthy controls undergoing the physical examination and 120 cases of hepatocellular carcinoma（HCC）by using the chemiluminescent and enzymatic methods respectively.The serum urea and creatinine levels were also measured.The estimated GFR（eGFR）was calculated.Results The serum PIVKA-Ⅱlevel had no statistical difference in among the healthy control group,renal disease with normal renal function group and renal disease with renal insufficiency group（H =2.902,P〈0.05）,moreover significantly lower than that in the HCC group（U=319.5,203.00,665.50 respectively,P〈0.001）.Serum PIVKA-Ⅱlevel had no statistical difference among various stages in the disease with renal insufficiency group（H=3.991,P〈0.05）.However,serum SA levels had statistical differences among the healthy control group,disease complicating normal renal function group and disease complicating renal insufficiency group（H = 63.685,P〈0.001）,and among the various stages in the disease complicating renal insufficiency group（H=64.689,P〈0.001）.The serum SA level was negatively correlated with eGFR level（r=-0.705,P〈0.001）,and positively correlated with Urea and Cr levels（r= 0.599,r= 0.704,P〈0.001）.The SA level in the HCC group was significantly increased compared with that in the stage 1-4of chronic kidney disease（CKD）（U=126.00,163.50,247.00,715.00 respectively,P〈0.001）,but had no obvious change compared with the stage 5of CKD（U=419.00,P〈0.05）.Conclusion The renal insufficiency has no obvious impact on serum PIVKA-Ⅱexpression,but could significantly increase the SA expression level,moreover is closely related with the severity of renal function impairment,thus indicating that the SA level increase not only has the assisted diagnosis value on HCC and multiple malignant tumors,but also better reflects the renal function status in the patients with chronic renal insufficiency.
