The purpose of the present work was to investigate whether there is an involvement of copper metabolism in the mechanism of gestational diabetes mellitus. No statistically significant differences were found in serum copper and ceruloplasmin concentrations between healthy pregnant women and women with gestational diabetes mellitus. The activity of ceruloplasmin in women with gestational diabetes mellitus was slightly higher and its specific activity significantly raised. The CuZn Superoxide dismutase activity was significantly increased (P < 0.05) in women with gestational diabetes mellitus, comparing the two groups by matched pairs according to age. The results indicate that oxidative stress may have a role in gestational diabetes mellitus and that reduced concentrations of copper are not the cause of this stress.
