Podocyturia in pregnant women with chronic hypertension may predict kidney injury?

To evaluate the presence of podocyturia in chronic hypertensive pregnant women in the third trimester of pregnancy and its possible association with renal disease. This was an observational study of a convenience sample of 38 chronic hypertensive pregnant women. The podocytes were labeled by the indirect immunofluorescence technique with anti-podocin and diamidino-phenylindole (DAPI). The count was made on 30 random fields analyzed and corrected according to urinary creatinine (podocytes/mg creatinine). The patients were assigned to two groups: NG (normal glomerular function), up to 100 podocytes, and GP (probable glomerulopathy), more than 100 podocytes. Urinary creatinine was measured by the alkaline picrate method. The variables analyzed were body mass index, gestational age, and systolic and diastolic blood pressure at the time of sample collection. Data were analyzed using the SPSS - version 16.0 (IBM - USA). Statistical analysis was performed by the χ2 test, and significant differences were considered when p
