Abstract
Introduction:
Glomerular hyperfiltration may lead to proteinuria and chronic kidney disease
in unilateral multicystic dysplastic kidney (MCDK). We aimed to investigate
the urine neutrophil-gelatinase-associated lipocalin (NGAL), netrin-1,
hepcidin, and C-C motif chemokine ligand-2 (MCP-1/CCL-2) levels in patients
with MCDK.
Methods:
Thirty-two patients and 25 controls were included. The urine hepcidin,
netrin-1, NGAL, and MCP-1/CCL-2 levels were determined by ELISA.
Results:
The
patients had higher serum creatinine
(Cr) levels, urine albumin, and netrin-1/
Cr ratio with lower GFR. There were
positive correlations between urine
protein/Cr, MCP-1/CCL-2/Cr, and
netrin-1 with NGAL (r = 0.397, p =
0.031; r = 0.437, p = 0.041, r = 0.323, p
= 0.042, respectively). Urine netrin-1/Cr
was positively correlated with MCP-1/
CCL-2/Cr (r = 0.356, p = 0.045). There
were positive associations between the
presence of proteinuria and netrin-1/
Cr, MCP-1/CCL-2/Cr, and NGAL/Cr
[Odds ratio (OR): 1.423, p = 0.037,
OR: 1.553, p = 0.033, OR: 2.112, p
= 0.027, respectively)]. ROC curve
analysis showed that netrin-1/Cr,
MCP-1/CCL-2/Cr, and NGAL/Cr had
high predictive values for determining
proteinuria p = 0.027, p = 0.041,
p = 0.035, respectively). Urine hepcidin/
Cr was negatively correlated with
tubular phosphorus reabsorption and
was positively correlated with urine
NGAL/Cr (r = -0.418, p = 0.019; r
= 0.682, p = 0.000; respectively).
Conclusions:
MCP-1/CCL-2 may play a role in the development of proteinuria in MCDK.
Netrin-1 may be a protective factor against proteinuria-induced renal
injury. Urine hepcidin/Cr may reflect proximal tubule damage in MCDK. Urine
NGAL/Cr may be a predictor of tubule damage by proteinuria.
