Abstract
Aim: Atherosclerosis involves vascular endothelial damage and lipid metabolism disorder, which is closely related to
the occurrence and development of diabetic kidney disease (DKD). However, studies on non-high albuminuria DKD
(NHADKD) with an albumin to creatinine ratio (ACR) <30mg/g are rare. This study is to investigate the relationship
between atherogenic factors and the occurrence of NHADKD.
Methods: Serum lipid indicators, lipoprotein-associated phospholipase A2 (Lip-PLA2) and homocysteine levels were
measured in 1116 subjects to analyze their relationship with NHADKD.
Results: Among all subjects, Lip-PLA2 had the closest but relatively weak correlation with ACR (r=0.297, p<0.001) and
only homocysteine was moderately correlated with eGFR (r=−0.465, p<0.001). However, in patients with NHADKD,
these atherosclerotic factors were weakly correlated or uncorrelated with eGFR (max. |r|=0.247). Stratified risk
analysis showed that when ACR was <10mg/g, homocysteine [OR=6.97(4.07–11.95)], total cholesterol (total-Chol)
[OR=6.04(3.03–12.04)], and high-density lipoprotein cholesterol (HDL-Chol) [OR=5.09(2.99–8.64)] were risk factors
for NHADKD. There was no significant difference of OR between these three factors (Z=0.430–1.044, all p>0.05).
When ACR was ⩾10mg/g, homocysteine [OR=17.26(9.67–30.82)] and total-Chol [OR=5.63(2.95–10.76)] were risk
factors for NHADKD, and ORhomocysteine was significantly higher than ORtotal-Chol (Z=3.023, p<0.05).
Conclusions: The occurrence of NHADKD may be related to the levels of homocysteine, total-Chol, HDL-Chol, and
Lip-PLA2 in blood. Among them, homocysteine may be most closely related to NHADKD.
