[The spectrum of lipids in the intrauterine growth retarded fetus and in the parents].
OBJECTIVE
The aim of this study was to determine the relationship between the parameters of individual serum lipids and the degree of intrauterine growth retardation (IUGR) of the fetus. The lipid levels were compared in fetuses with IUGR and in eutrophic fetuses and it was determined in which studied variable IUGR newborns differ from healthy newborns.


METHODS
The group under study consisted of 53 pregnant women in whom IUGR of the fetus was diagnosed by ultrasound during pregnancy. The control group consisted of 26 women who gave birth to eutrophic newborns. The cases in the control group were chosen by the method of matched control so that the results could be statistically evaluated in both groups at the same gestational age and at the same maternal age. In both groups blood samples from the umbilical cord were taken after delivery and the whole spectrum of lipid levels were evaluated (cholesterol-CH, triglycerides-TGA, high-density lipoprotein--HDL, low-density lipoprotein--LDL, Lp(a) lipoprotein, and apolipoproteins-ApoB, ApoAI, ApoE). The same parameters were evaluated in maternal and paternal blood samples. In several cases, intrauterine lipid levels of the fetus were determined by cordocentesis. The incidence of hyperlipoproteinemia in the families of both groups was surveyed.


METHODS
Department of Obstetrics and Gynaecology, 1st medical Faculty, Charles University, Prague.


RESULTS
There was a significant incidence of hyperlipoproteinemia in the families of the mothers in the group studied (chi-square test: p < 0.001). In the mothers of the groups studied, there were statistically significant higher levels of HDL, LDL, and Lp(a) in comparison to the mothers in the control group. A significant dependence was determined between the levels of ApoAI and Lp(a) of the mothers and newborns. In the regression analysis of the dependence of lipid levels on the birth weight of the newborns, a statistical correlation was determined for the values of ApoB and Lp(a).


CONCLUSIONS
The more increased the intrauterine growth retardation of the fetus and the lower its birth weight in relation to its gestational age, the higher its lipid levels, specifically apolipoproteins. Apolipoproteins are under genetic control and present a genetic risk for changes in the metabolism of cholesterol, hemocoagulation, and cardiovascular disease in adulthood.
