Maternal cytoglobin (CYGB) serum levels in normal and preeclamptic pregnancies.

Objective: To investigate cytoglobin levels in women with preeclampsia and women with uncomplicated pregnancies.Materials and methods: A cross-sectional study including 26 pregnant women complicated with early-onset preeclampsia (EO-PE) and 26 pregnant women complicated with late-onset preeclampsia (LO-PE) were recruited for the study group. Twenty-seven healthy pregnant women selected randomly were included in the control group. The serum CYGB concentrations were measured using an enzyme-linked immunosorbent assay.Results: Gestational age at delivery and mean birth weight were significantly lower in the preeclampsia groups than in the control group and were found to be the lowest in the EO-PE group (p<.001). Serum CYGB levels were significantly higher in the EO-PE and LO-PE groups as compared with the control group (9.99 (6.08) ng/ml (EOPE), 10.04 (7.04) ng/ml (LOPE) versus 2.84 (0.82) ng/ml), (p<.001). However, a significant difference was not found between the EO-PE and LO-PE groups regarding CYGB levels (p=1.000).Conclusions: Serum CYGB levels were significantly higher in patients with EO-PE and LO-PE as compared to healthy pregnant women.
