Objectives: The early diagnosis of volume overload in
chronic kidney disease (CKD) is very important. N-terminal pro-brain
natriuretic peptide (NT-proBNP) is a valuable biomarker for this
purpose. Our study aimed to detect the relationship between NT-proBNP
and left ventricular hypertrophy (LVH), hypertension (HT), GFR, and
proteinuria among diabetic patients with stage 3-4 CKD.
Methods: 160 diabetic patients with stage 3-4 CKD [80
patients in stage 3 CKD (group 1) and 80 patients in stage 4 CKD (group
2)] were enrolled. NT-proBNP levels were evaluated in serum, and
proteinuria was determined from 24-hour collected urine. Left
ventricular hypertrophy was evaluated by M-mode echocardiography.
NT-proBNP levels were compared according to their left ventricular
hypertrophy, hypertension, and proteinuria levels.
Results: NT-proBNP levels was significantly higher,
and GFR was lower in group 2 compared to group1 (p < 0.05). NT-proBNP
was higher in patients with LVH (+) HT (+) and proteinuria ≥ 1gr/d than
patients with LVH (-), HT (-), and proteinuria < 1g/d (p < 0.05).
We found a significant correlation between NT-proBNP levels and left
ventricular posterior wall thickness, diastole (LVPWTd), proteinuria,
SBP, and DBP. Proteinuria was the major contributor to increased
NT-proBNP levels among the independent variables.
Conclusion: We detected that NT-proBNP levels are
increased during the progression of CKD, and proteinuria is the major
cause of increased NT-proBNP levels among the independent variables.
