[Microalbuminuria in pregnancy: effect of glucose tolerance and gestational age].

: Renal hemodynamic changes and insulin-resistance are normally observed in pregnancy. This study was aimed at evaluating the presence of microalbuminuria in normotensive pregnant subjects with normal or abnormal glucose tolerance. Nineteen pregnant women have been evaluated by oral glucose tolerance test (OGTT, 100 g) and by urine testing for microalbuminuria at 10 weeks of gestation. Eighteen and 14 women have been reexamined respectively at 24 and 32 weeks of gestation. In the subjects examined there was no correlation between microalbuminuria and abnormal glucose tolerance. Microalbuminuria, however, absent when the subjects were examined at 10 weeks of pregnancy, was present in 36% of women examined at 32 weeks of gestation. In conclusion, probably due to renal hemodynamic changes, microalbuminuria appears frequently in late pregnancy.
