Introduction. Copper is essential micronutrient and has an important role in
the human body. The serum copper increases during pregnancy and is doubled at
full term. Lower levels of serum copper in pregnancy are connected with some
pathological conditions. Objective. The aim of this study was to estimate the
levels of serum copper in normal and pathological pregnancies, comparing them
with values of serum copper in non-pregnant women, to determine if serum
copper is lower in some pathological pregnancies and if this is of some
importance. Methods. A total of 2170 plasma samples for copper analyses were
made in the following groups: healthy non-pregnant women; healthy pregnant
women from the 5th-40th gestational week, during the first delivery stage and
during the first three postpartum weeks, in pregnant women with habitual
abortion, imminent abortion, abortion in progress, missed abortion (9th-24th
weeks), missed labour and premature rupture of membranes (29th-40th weeks).
Levels of serum copper were determined by colorimetric technique of
bathocuproin with disulphate as a chromogen. Results. Serum copper values in
non-pregnant women range from 11.6-25.8 μmol/L. In healthy pregnant women,
there is a constant trend of the increase of serum copper. The mean serum
copper values revealed three significant peaks at the 22nd, 27th and 35th
gestational week. Serum copper values in the patients with some pathological
pregnancies in relation to the serum copper values of the healthy pregnant
women were significantly lower. Conclusion. Serum copper values can be used
as an indicator of some pathological pregnancies.
