comparison of serum trace element levels in patients with or without pre-eclampsia

objective: in developing countries, nutritional deficiency of essential trace elements is a common health problem, particularly among pregnant women because of increased requirements of various nutrients. accordingly, this study was initiated to compare trace elements status in women with or without pre-eclampsia. materials and methods: in this study, serum trace elements including zinc (zn), selenium (se), copper (cu), calcium (ca) and magnesium (mg) were determined by using atomic absorption spectrometry (aas) in 60 patients and 60 healthy subjects. results: there was no significant difference in the values of cu between two groups ( p >0.05 ) . a significant difference in zn, se, ca and mg levels were observed between patients with pre-eclampsia and control group ( p <0.001, p <0.01, p <0.01 and p <0.001, respectively). zn, se, ca and mg levels were found to be 76.49±17.62 μg/dl,   8.82±2.10 μg/dl, 8.65± 2.14 mg/dl and 1.51±0.34 mg/dl in pre-eclamptic cases, and these values were found statistically lower compared to the controls (100.61±20.12 μg/dl, 10.47±2.78 μg/dl, 9.77±3.02 mg/dl and 1.78±0.27 mg/dl, respectively). while cu levels were 118.28±16.92 and 116.55±15.23 μg/dl in the patients and the healthy subjects, respectively. in addition, no significant difference was found between two groups with respect to hemoglobin concentration (hbc) and total white blood cell count (twbc) ( p >0.05). conclusion: our findings indicate that the levels of zn, se, ca and mg are significantly altered in pregnant women with pre-eclampsia. this research shows that these deficiencies can not due to hemodilution.
