Serum Soluble Endoglin and Matrix Metalloproteinase 14 With Elisa Method in Early/Late-onset Preeclampsia
Study Details
Study Description
Brief Summary
Objective: Defective placentation and inadequate trophoblastic invasion have an important place in the aetiology of preeclampsia (PrE). Trophoblasts invade the maternal decidua and remodel spiral arteries with matrix metalloproteinase-14 (MMP-14). To the best of our knowledge, studies of MMP-14 protein levels of PrE patients' sera remain unpublished. This study aims to investigate the value of serum MMP-14 and soluble endoglin (s-ENG) in PrE patients and healthy controls.
Methods: The study was conducted with 30 late-onset preeclampsia patients (L-PrE) as group1 (gestational age≥34 weeks), 33 patients with normal pregnancies as group2 (gestational age≥34 weeks), 31 early-onset preeclampsia patients (E-PrE) as group3 (gestational age<34 weeks), and 31 patients with normal pregnancies as group 4 (gestational age<34 weeks). Serum MMP-14 and s-ENG levels measured by ELISA were compared.

Detailed Description
The study was conducted at Cengiz Gokcek Women's and Children's Hospital, Gaziantep, Turkey at department of obstetrics and gynecology between date of January 2018 and December 2018. The study protocol was designed according to the Declaration of Helsinki, and the institutional ethical review board of Gaziantep University approved the study (Reference number: 2018/91). One hundred twenty-five women enrolled in the study in four groups. The investigators consecutively recruited 61 pregnancies complicated with preeclampsia, and 64 healthy pregnancies will select for the control group. All participiants gave their oral and written informed consent before their inclusion in the study.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| late-onset preeclampsia, group1 30 late-onset preeclampsia patients as group1 (gestational age≥34 weeks). The diagnosis of preeclampsia, as defined by the Committee on Terminology of the American College of Obstetricians and Gynecologists (ACOG), will establish based on the presence of proteinuria (urinary excretion of 300 mg protein or higher, or at least 1+in dipstick in a 24-h urine specimen) and a blood pressure level of ≥140/90mmHg (two blood pressure measurements 6 h apart) that occurs after 20 weeks of gestation in a previously normotensive woman. Diastolic and/or systolic blood pressure up to 110/160 mm Hg will consider mild, and higher values will consider to being severe. |
Other: MMP-14 and s-ENG levels
Venous blood sampled from the antecubital veins for measuring the serum concentration of MMP-14 and s-ENG levels. The serum MMP-14 and s-ENG levels measured using commercially available reagent kits, which is produced to detect human MMP-14 and s-ENG levels (Rel Assay Diagnostics Gaziantep, Turkey). The MMP-14 and s-ENG levels measurements were performed in accordance with the company's protocol.
|
| Control, group 2 33 patients with normal pregnancies as group2 (gestational age≥34 weeks). The control groups' samples obtained during the routine obstetrical care examination in the third trimester of pregnancy. Then these pregnant women followed-up until the delivery. |
Other: MMP-14 and s-ENG levels
Venous blood sampled from the antecubital veins for measuring the serum concentration of MMP-14 and s-ENG levels. The serum MMP-14 and s-ENG levels measured using commercially available reagent kits, which is produced to detect human MMP-14 and s-ENG levels (Rel Assay Diagnostics Gaziantep, Turkey). The MMP-14 and s-ENG levels measurements were performed in accordance with the company's protocol.

| early-onset preeclampsia, group 3 31 early-onset preeclampsia patients as group3 (gestational age<34 weeks). The diagnosis of preeclampsia, as defined by the Committee on Terminology of the American College of Obstetricians and Gynecologists (ACOG), will establish based on the presence of proteinuria (urinary excretion of 300 mg protein or higher, or at least 1+in dipstick in a 24-h urine specimen) and a blood pressure level of ≥140/90mmHg (two blood pressure measurements 6 h apart) that occurs after 20 weeks of gestation in a previously normotensive woman.

Outcome Measures
Primary Outcome Measures
- Serum matrix metalloproteinase-14 levels in preeclampsia [1 day]
The primary endpoint in this analysis is to evaluate the value of serum matrix metalloproteinase-14 levels (ng/ml) in preeclampsia patients and also address its relationship with its severity.
Secondary Outcome Measures
- Serum soluble endoglin levels in preeclampsia [1 day]
The secondary endpoint in this analysis is to evaluate the value of serum soluble endoglin levels (ng/ml) in preeclampsia patients and also address its relationship with its severity.
