Abstract

Objective: The aim of this study was to measure serum zinc-α2-glycoprotein (ZAG) in pregnant Egyptian females with preeclampsia and eclampsia and to correlate its levels to biochemical measures of kidney function, lipid and glucose metabolism.
Study Design: It was a retrospective study.
Patients and Methods: This study measured ZAG levels by enzyme linked immunosorbent assay (ELISA) in pregnant females with preeclampsia (PE) (no. = 40) and eclampsia (no.=20) and were compared to healthy gestational age-matched subjects (no.=20). In addition, the association of ZAG with kidney function, lipid and glucose metabolism was studied.
Results: Significant difference was detected on comparing the different groups regarding ZAG levels (p = 0.001). Furthermore, ZAG was positively correlated to systolic blood pressure, urinary protein, fasting insulin and HOMA-IR.After adjusting for other parameters,the association between ZAG and SBP, urinary protein, serum insulin and HOMA-IR remained significant by multivariate linear regression analysis.
Conclusion: The study noted that maternal ZAG serum levels are significantly increased in PE
