ABSTRACT
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.
RESUMO
Resumo

Introdução:

A hiperfiltração glomerular pode causar proteinúria e doença renal crônica no rim displásico multicístico unilateral (RDM). Nosso objetivo foi investigar os níveis de lipocalina associada à gelatinase neutrofílica na urina (NGAL), netrina-1, hepcidina e quimiocina C-C com ligante-2 (MCP-1/CCL-2) em pacientes com RDM.

Métodos:

Trinta e dois pacientes e 25 controles foram incluídos. Os níveis urinários de hepcidina, netrin-1, NGAL e MCP-1/CCL-2 foram determinados por ELISA.

Resultados:

Os pacientes apresentaram níveis séricos mais elevados de creatinina (Cr), albumina na urina e relação netrina-1/Cr com menor TFG. Houve correlação positiva entre proteína na urina/Cr, MCP-1/CCL-2/Cr e netrina-1 com NGAL (r = 0,397, p = 0,031; r = 0,437, p = 0,041, r = 0,323, p = 0,042, respectivamente). A netrina-1/Cr na urina foi correlacionada positivamente com MCP-1/CCL-2/Cr (r = 0,356, p = 0,045). Houve associações positivas entre a presença de proteinúria e netrina-1/Cr, MCP-1/CCL-2/Cr e NGAL/Cr [Odds ratio (OR) 1,423, p = 0,037, OR 1,553, p = 0,033, OR 2,112, p = 0,027, respectivamente) ]. A análise da curva ROC mostrou que netrina-1/Cr, MCP-1/CCL-2/Cr e NGAL/Cr apresentaram altos valores preditivos para determinar a proteinúria p = 0,027, p = 0,041, p = 0,035, respectivamente). A hepcidina/Cr na urina foi correlacionada negativamente com a reabsorção tubular de fósforo e positivamente com a NGAL/Cr na urina (r = -0,418, p = 0,019; r = 0,682, p = 0,000; respectivamente).

Conclusões:

MCP-1/CCL-2 pode ter participação no desenvolvimento de proteinúria no RDM. A Netrina-1 pode ser um fator protetor contra lesão renal induzida por proteinúria. Hepcidina/Cr na urina pode refletir danos em túbulos proximais no RDM. O valor de NGAL/Cr urinário pode ser um preditor de danos nos túbulos por proteinúria.
