sFlt-1:PlGF Ratio in Gestational Diabetes: PREDICTION (PREeclampsia in DIabetiC gestaTION) Study (PREDICTION)

May 5, 2021 updated by: Cristina Bianchi, Azienda Ospedaliero, Universitaria Pisana

Predictive Value for Preeclampsia of the sFlt-1:PlGF (Soluble Foms-like Tyrosine Kinase 1/Placental Growth Factor) Ratio in Pregnancy Complicated by Gestational Diabetes: The PREDICTION (PREeclampsia in DIabetiC gestaTION) Study

The ratio of soluble fms-like tyrosine kinase 1 (sFlt-1) to placental growth factor (PlGF) is elevated in pregnant women before the clinical onset of preeclampsia and can be used to predict the preeclampsia. However, its predictive value in pregnancy complicated by gestational diabetes is unclear. This study purposes are to validate a ratio of serum sFlt-1 to PlGF that would be predictive of the absence or presence of preeclampsia in the short term in women with singleton pregnancies complicated by diabetes in whom preeclampsia was suspected, and to evaluate the relationship among sFlt-1 to PlGF and placental histopathological alterations.

Detailed Description

Single center, observational, prospective study designed to validate a cutoff point of the sFlt-1:PlGF ratio for the prediction of the short-term absence or presence of preeclampsia in pregnancy complicated by gestational diabetes (GDM).

GDM women will be recruited at diabetes screening time (16-18 or 24-27 gestational weeks), performed according with the Italian National Guidelines by 75g - 2 hour Oral Glucose Tolerance Test. GDM will be defined according with International Association of Diabetes and Pregnancy Study Groups/World Health Organization 2013 criteria. A standardized medical history will be obtained in all the women at the time of their first visit, collecting data about maternal age, parity, last menstruation, pre-gestational weight, history of GDM, hypertension and macrosomia in previous pregnancies, family history of diabetes mellitus, education and employment. Moreover, during their visit, the women's weights were taken and their blood pressure measured. Blood samples for assessments of sFlt-1:PlGF ratio will be collected at visit 1 (baseline visit) and every 30±7 days after the previous visit until 36 gestational week (for a maximum of 4 determinations). At baseline and at each follow-up visits update of medical history, clinical assessments, laboratory testing and pregnancy evolution will be evaluated. During pregnancy all women will be receive standard diabetes and obstetric care, according with national guidelines. Diagnostic criteria for preeclampsia will be a new onset of both hypertension (systolic blood pressure ≥140 mmHg, diastolic blood pressure ≥90 mmHg, or both) and proteinuria (2+ protein or greater on dipstick urinalysis, ≥300 mg of protein per 24-hour urine collection, ≥30 mg /dl of protein in a spot urine sample, or a ratio of protein to creatinine of ≥30 mg/mmol) after 20 weeks of gestation. Only cases that met these prespecified criteria will be included in the analyses. At delivery, data items on maternal body weight at the end of pregnancy, time and mode of delivery, newborn bodyweight, preeclampsia as well as other maternal and fetal outcomes will be collected. Placental histopathological alterations will be detected in women who delivery by planned Cesarian section.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Female

Sampling Method

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Predictive SFLT-1 / PLGF ratio cat-off point for preeclampsia
Time Frame: 25 weeks
Evaluation of a specific SFLT-1 / PLGF ratio cat-off point for women with diabetes during pregnancy (pre-pregnancy or gestational) in the prediction of preeclampsia
25 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Correlation between SFLT-1 / PLGF ratio and placental histopathology
Time Frame: 25 weeks
Correlation between SFLT-1 / PLGF ratio and rate of placental histopathological alterations in pregnancy complicated by diabetes (pre-pregnancy or gestational)
25 weeks

Primary Completion (ANTICIPATED)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
