Study summary

In pregnancies with gestational diabetes (GDM), a protein called MST1 is significantly higher in both mothers and baby cord blood. This suggests MST1 plays a key role in the disease. However, because patients managed their blood sugar well, these high levels did not cause short-term health problems. This is also the very first study to check MST1 in both mothers and babies.

Read the detailed description

Maternal and cord blood MST1 levels are significantly elevated in pregnancies complicated by GDM, suggesting a role in the underlying pathophysiology. However, MST1 does not appear to be associated with short-term clinical outcomes, possibly due to effective glycemic control. To our knowledge, this is the first study to evaluate MST1 in both maternal and fetal sections in pregnancies complicated by gestational diabetes.

What researchers measure

Primary outcomes

  1. Maternal serum Mst1 and cor blood MST1 levels will be collected

    Maternal demographic and clinical data, including age, gravida, parity, gestational age, and body mass index (BMI), will be recorded for all participants. Gestational age was determined based on the last menstrual period and/or first-trimester ultrasound findings. All participants underwent physical examination, obstetric ultrasound, and routine laboratory testing. All participants underwent a 75-g oral glucose tolerance test (OGTT) between 24 and 28 weeks of gestation following an overnight fast of at least 8 hours. Maternal venous blood samples were collected in the morning after an overnight fast under standardized conditions to minimize circadian and metabolic variability. Cord blood samples were obtained immediately after delivery from the umbilical vein using a standardized protocol. Serum MST1 levels will be measured using a commercially available enzyme-linked immunosorbent assay (ELISA) kit. Obstetric and neonatal outcomes will be recorded,

    Time frame: 1 year

  2. Obstetric and neonatal outcomes will be recorded

    Obstetric and neonatal outcomes will be recorded, including gestational age at delivery, mode of delivery, birth weight, 1st- and 5th-minute Apgar scores, and neonatal intensive care unit (NICU) admission, transient tachypnea of the newborn (TTN), respiratory distress syndrome (RDS), and intubated infants. Maternal and perinatal outcomes will be compared with serum and cord blood MST-1 levels.

    Time frame: 6 month

  3. Maternal characteristics affecting MST1 levels will be determined.

    It will be evaluated whether maternal demographic characteristics and blood parameters influence serum and cord MST1 levels.

    Time frame: 6 months

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jul 2025 to primary completion in Jul 2026, 12 months.

Of 133 non-industry observational studies under Diabetes, Gestational, half reached primary completion within 43 months of starting (the median), counting those still running; a quarter within 23 and three quarters within 70. This study's 12 months is below that.

Counting every sponsor, half of 135 studies reached it within 42 months; a quarter within 23 and three quarters within 70.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
