Renal tubular markers in pregnant women with and without gestational diabetes mellitus: a pilot study

Second-trimester urinary neutrophil gelatinase-associated lipocalin levels in gestational diabetes: preliminary results

OBJECTIVE

The objective of this study is to investigate the urinary neutrophil gelatinase-associated lipocalin (uNGAL) levels in the second trimester of pregnant patients at the time of gestational diabetes mellitus (GDM) screening.

MATERIALS AND METHODS

Urinary samples from 88 pregnant women who underwent gestational diabetes screening test were collected in late second trimester (24-28 weeks) prospectively. After an overnight fasting, 75 g GTT was performed. The blood samples were drawn for measurement of glucose, insulin, and HbA1c. The urinary and blood parameters were compared for pregnant women with or without gestational diabetes.

RESULTS

uNGAL levels were significantly elevated in pregnant women with gesting compared with the control groups (p < .014). There was a positive correlation between uNGAL and HbA1c levels (p = .001).

CONCLUSIONS

In the second trimester, at the time of GDM screening, high levels of uNGAL indicate tubular injury in GDM cases which seems to be a result of hyperglycemia. uNGAL may correlate with an inflammatory renal involvement in GDM.

Urinary liver-type fatty acid-binding protein change in gestational diabetes mellitus

We compared urinary liver-type fatty acid-binding protein (L-FABP) among non-pregnant and pregnant women with and without gestational diabetes mellitus (GDM). Higher urinary L-FABP was found in pregnant with and without GDM, and considerably higher urinary L-FABP was found in the GDM group compared with the non-GDM group. Hyperglycemia and anemia were related with high urinary L-FABP expression.
