The Value of Second-trimester Uterine Artery Doppler Analysis in the Prediction of GDM in a Low- Risk Population (PS-GDM-2022)

August 2, 2022 updated by: Filiz Yarsilikal Guleroglu, Haseki Training and Research Hospital
In the current literature, there are not enough studies related to the use of uterine artery Doppler indices in the second trimester for the prediction of GDM. Considering that it may be useful in the prediction of GDM in low-risk patient groups for GDM, it was found useful to consider uterine artery Doppler analysis within the scope of this study.In this study, the investigators aimed to assess the value of second-trimester uterine artery Doppler analysis in the prediction of GDM in a low- risk population.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This retrospective research was conducted between June 2020 and December 2021 at the Perinatology Clinic of Haseki Training and Research Hospital. Maternal age between 18 and 42 years and gestational age between 18 and 23 weeks were the inclusion criteria.Pregnant women's computerized records were used to compare the relevant data of women diagnosed with gestational diabetes and women with normal glucose tolerance . Transabdominal ultrasonography was performed for anatomical scanning, and the uterine artery Doppler was obtained using ultrasonographic devices with a 2.0-7.0 megahertz convex probe. The uterine artery waveforms were obtained using pulsed-wave Doppler with an insonation angle of 30° and a peak systolic velocity greater than 60 cm/s. Three identical waveforms were obtained consecutively on each side. In addition to recording the presence or absence of notching, the mean uterine artery pulsatility index (UAPI) was also obtained. Abnormal uterine artery Doppler was defined as a mean UAPI greater than the 95th percentile for each gestation.Increased uterine artery pulsatility index and/or diastolic notch in the uterine artery between 18-23 weeks of pregnancy can predict the risk of GDM in pregnant women.

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.

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
Uterine artery Doppler ultrasonography in gestational diabetes mellitus
Time Frame: Through study completion, an average of 18 months
To investigate and compare uterine artery pulsatility index by Doppler ultrasonography in patients with gestational diabetes mellitus (GDM) and without to non-diabetic controls.
Through study completion, an average of 18 months

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
Prediction of GDM with uterine artery pulsatility index cut-offs
Time Frame: Through study completion, an average of 18 months
Cut off values of uterine artery pulsatility index will be estimated to predict GDM
Through study completion, an average of 18 months

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 10, 2021

Primary Completion (Actual)

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.
