چکیده انگلیسی
Copper is an essential element required for the formation of many enzymes with important roles in the human body. During pregnancy, the maternal serum copper concentration is increased due to the higher levels of ceruloplasmin that are the result of elevated oestrogen levels. The aim of this work was to investigate maternal plasma copper concentrations in relation to various pathological conditions during pregnancy. A total of 319 maternal plasma samples were analysed: 103 taken from women in the first trimester, 73 in the second trimester, 99 in the third trimester of pregnancy and 44 at delivery. The plasma concentration of copper during each trimester of normal pregnancy was taken as a reference value. Group comparisons performed by analysis of variance (ANOVA) followed by Dunnett test indicated substantially lower plasma concentrations of copper in pathological conditions diagnosed during the first trimester of pregnancy (spontaneous abortion, threatened abortion, missed abortion and blighted ovum). No significant differences in maternal plasma blood copper concentrations were found in pathological conditions (threatened abortion, threatened preterm delivery and pyelonephritis) diagnosed in the second trimester of pregnancy. Significant differences in plasma copper concentrations were found in the third trimester, for which finding the Dunnett test indicated the cholestasis group to be responsible. Except for twin pregnancy, a tendency to higher plasma copper concentrations, however not statistically significant, was observed in other pathological conditions during the third trimester (gestosis, intrauterine growth retardation, preterm labour).
