[Evaluation of fetal condition in pregnancy complicated by hypertension--biochemical assessment of amniotic fluid. I. Protein and lipid components and kidney maturation]. / Ocena stanu wewnatrzmacicznego plodu w nadcisnieniu tetniczym krwi--poprzez badania biochemiczne plynu owodniowego. I. Skladniki bialkowe, lipidowe i dojrzalosci nerek.

Sixty two samples of amniotic fluid were submitted to biochemical investigation including 31 samples from women with pregnancy complicated by hypertension (studied group with mean blood pressure 165 +/- 15/95 +/- 5 mmHg) and 31 samples deriving from healthy pregnant women (control group with mean blood pressure 118 +/- 10/74 +/- +/- 9 mmHg). In the studied group pregnancy induced hypertension, primary hypertension and nephrogenic hypertension scored 58%, 32% and 10% of cases respectively. Both investigated and control groups consisted of pregnant women with the same gestational age of 37 +/- 2 weeks (34-40 weeks). The following parameters of amniotic fluid were measured: 1) total protein, 2) albumin, 3) beta-lipoprotein, 4) cholesterol, 5) uric acid, 6) urea, 7) creatinine. Micromethods were used. Amniotic fluid deriving from women with pregnancy complicated by hypertension showed decreased concentrations of total protein, albumin and beta-lipoprotein. In pregnancy complicated by hypertension kidneys of the fetuses were estimated to be as mature as in the normal pregnancy within the same gestational age.
