Abstract:
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 un‐dergoing 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‐Ⅱ level had no statistical difference in among the healthy control group ,renal disease with normal renal func‐tion 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‐Ⅱ level had no statistical difference among vari‐ous 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 1-4 of 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 5 of CKD(U=419 .00 ,P>0 .05) .Conclusion The renal insufficiency has no obvious im‐pact on serum PIVKA‐Ⅱexpression ,but could significantly increase the SA expression level ,moreover is closely related with the se‐verity 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 .
