Serum Soluble Endoglin and Matrix Metalloproteinase 14 With Elisa Method in Early/Late-onset Preeclampsia

An Analysis Soluble Endoglin and Matrix Metalloproteinase 14 With Elisa Method in the Diagnosis and Severity of Early/Late-onset Preeclampsia

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 To the best of our knowledge, studies of MMP-14 protein levels of PrE patients' sera remain unpublished.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.

Study Overview

• Status: Completed
• Conditions: Preeclampsia
• Intervention / Treatment: Other: MMP-14 and s-ENG levels

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.

Preeclampsia is a pregnancy complication characterized by high blood pressure and signs of damage to another organ system, most often the liver and kidneys. Preeclampsia usually begins after 20 weeks of pregnancy in women whose blood pressure had been normal. Early-onset preeclampsia is usually defined as preeclampsia that develops before 34 weeks of gestation, whereas late-onset preeclampsia develops at or after 34 weeks of gestation.

Description

Inclusion Criteria:

Cohorts and Interventions

Group / Cohort	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.
