    Abstract:
    Insulin concentrations of 284 amniotic fluid samples were assessed, obtained from pregnant women by genetic amniocentesis between the 16-18 gestational weeks. The indication of amniocentesis was either advanced maternal age (> 35 years) or high risk genetic history. The amniotic fluid insulin concentration (mean +/- SD) was found 3.8 +/- 3.0 microIU/ml. The insulin concentration in 4.3% of all pregnant women was higher than the mean value +2 SD (9.8 microIU/ml) which represents individual pathological value, characteristic for gestational diabetes. Our data suggest that one part of gestational diabetes might be detected between the 16-18 gestational weeks, therefore we propose an earlier screening as the usual one. At institutes where the possibility of genetic amniocentesis is given the determination of insulin level in amniotic fluid may be reasonable. We could analyze the outcome of 230 pregnancies analysed. A close correlation was found between the amniotic fluid insulin concentration and birthweights of female newborns. It could not found such correlation at male newborn. A more careful screening test for gestational diabetes should be performed at mothers with female fetuses.
