Serum Netrin-1 and Urinary KIM-1 levels as potential biomarkers for the diagnosis of early preeclampsia

Abstract

The aim of this study was to evaluate whether the Serum Netrin-1 and Urinary KIM-1 (Kidney Injury Molecule-1) levels are associated with the detection of preeclampsia. A total of 90 patients, including 36 normal pregnant women, 29 patients with nonsevere preeclampsia and 25 patients with severe preeclampsia, were included in this study. Maternal serum Netrin-1 and Urinary KIM-1 levels were measured by using an enzyme-linked immunosorbent assay (ELISA). The results showed that the Levels of Netrin-1 and KIM-1 were statistically higher in women with preeclampsia as compared with normal pregnant women. Furthermore, the Netrin-1 level in women with severe preeclampsia was significantly higher than nonsevere preeclamptic women. inconclusion the current study showed that Maternal serum level of Netrin-1 and Urinary level of KIM-1 can be used as early biomarkers for the detection of preeclampsia.

IMPACT STATEMENT

• What is already known on this subject? Preeclampsia is a disorder of widespread vascular endothelial malfunction and vasospasm that occurs after 20 weeks' gestation. Netrin-1 was found to promote angiogenesis. Alteration of placental angiogenesis in early pregnancy is a well-known reason for placental dysfunction such as preeclampsia. Kidney injury with proteinuria is a characteristic feature of preeclampsia. Urine KIM-1 is the most potential biomarker for renal injury in preeclampsia. Due to these facts, we aimed to investigate the role of maternal serum Netrin-1 and Urine KIM-1 levels in preeclampsia presence and severity.

• What the results of this study add? A significant relationship between Netrin-1 and KIM-1 levels with preeclampsia.

• What the implications are of these findings for clinical practice and/or further research? Based on these findings, we concluded that increased levels of Netrin-1 and KIM-1 are associated with severe preeclampsia.
