[The concentration of selenium in the maternal serum in cases of missed abortion].

The changes in the serum level of selenium in cases with pathologic pregnancies are still not clear. The aim of the present study was to determine whether serum selenium in cases with missed abortion differed from selenium concentration in serum during first trimester of normal pregnancy. Twenty-three women with missed abortion and 61 with normal pregnancy were included in the study. We found a statistically significant (p < 0.001) elevation of serum selenium level in cases with missed abortion (928 +/- 335 nmol/l) comparing with those with normal pregnancy (568 +/- 77 nmol/l). We discuss the possible mechanisms of the observed changes.
