Objective: The aim of this study was to investigate the maternal serum concentrations of copper (Cu) and ceruloplasmin (CP) in patients with mild preeclampsia, severe preeclampsia, hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome, and to determine their association with the severity of the disease.Methods: This study was carried out at the largest tertiary care health center in the southeast region in Turkey and Department of Obstetrics and Gynecology, Dicle University Hospital. A total of 179 pregnant women, including 58 healthy pregnant women and 71 mild preeclampsia, 26 severe preeclampsia, and 24 HELLP syndrome cases classified according to the American College of Obstetricians and Gynecologists' 2013 guidelines were included in this prospective study. Blood samples were taken from all the pregnant women to evaluate the serum Cu and CP levels. The Cu level was determined via atomic absorption/emission spectroscopy, while the serum CP level was assessed with a nephelometric assay using an automatic image analyzer. Spearman's rank correlation tests were used to determine the correlations between the serum levels of the antioxidative markers and the preeclampsia severity.Results: The mean ± SD of the Cu was 81.2 ± 11.84 µg/dl in the mild preeclampsia cases and 160.2 ± 20.89 µg/dl in the severe preeclampsia cases (p < .001). The mean ± SD of the CP was 33.0 ± 4.81 mg/dl in the mild preeclampsia cases and 65.3 ± 9.17 mg/dl in the severe preeclampsia cases (p < .001). The Cu and CP levels were significantly higher in the patients with HELLP syndrome, which is an advanced and more severe form of severe preeclampsia, than in the mild and severe preeclampsia patients (p < .001 and p < .001, respectively). Therefore, the serum Cu and CP levels were correlated with the severity of preeclampsia (r = 859, p < .001 and r = 786, p < .001, respectively). In addition, there was a positive correlation between the serum Cu and CP levels and the systolic and diastolic blood pressure values and aspartate amino transferase levels (AST), and a negative correlation between the serum Cu and CP levels and the platelet count.Conclusion: This was the first study in which the ceruloplasmin and Cu levels were investigated in HELLP syndrome patients. When considering the results obtained in the present study, there were significant relationships between the Cu, CP levels which are the markers of oxidative stress and the preeclampsia severity.

Abstract: Project: The aim of the study was to investigate the serum reference range for Selenium (Se), Zinc (Zn) and Copper (Cu) levels in women of 10–14 (group I) and 16–20 (group II) weeks of gestation and compare them with those in non-pregnant healthy women and healthy men. Procedure: This cross-sectional study was performed in 351 pregnant women [group I (n: 177) and group II (n: 174)], 30 non-pregnant women and 30 men as controls. The levels of Se, Zn and Cu levels were determined on flame and furnace atomic absorption spectrophotometer using Zeeman background correction. Results: In the 10–14 weeks of gestation Se, Zn and Cu serum levels were 44.85±9.23, 81.30±31.94 and 132.33±38.24ug/dl, in 16–20 weeks of gestation were 47.18±10.92, 74.25±22.47 and 164.86±39.69ug/dl, in non-pregnant women were 55.38±8.81, 121.41±29.22 and 104.75±39.14ug/dl also in men 72.24±9.28, 134.85±15.95 and 78.29±20.90ug/dl, respectively. Conclusion: A significant low level of serum Se, Zn and a high level of Cu in the pregnant women in the 10–14 and 16–20 weeks of gestation were detected when compared with that of non-pregnant women and men.
