[Serum lipid and lipoprotein concentrations in pregnancy and at onset of labor in normal and complicated pregnancies caused by hypertensive gestosis and fetal growth retardation].

Cholesterol triglyceride and lipoprotein concentrations were determined in the sera of 220 pregnant women at different periods of their pregnancy. In 197 healthy pregnant women we found besides an increase in cholesterol level and in particular an increase in the beta-lipoprotein fractions, a marked increase in pre-beta-lipoprotein levels and more than twice as high triglyceride concentration in the course of the first to the third trimenon. Nothing abnormal was found on comparing the lipid and lipoprotein parameters of 13 pregnant women having hypertensive toxaemia, with those of healthy gravidae, with the exception of a marked increase in the pre-beta-lipoprotein levels in those patients who suffered from toxaemia. No connection was seen between infantile deficient development below the tenth percentile and the serum lipid and lipoprotein concentrations (n = 10) in the mother. Examinations carried out in 233 pregnant women and their children at the time of birth did not yield any connections between maternal and infantile protein patterns. All infants had definitely lower parameter concentrations than their mothers.
