Brief summary

This cohort study investigated whether IRAP levels could be a marker for predicting gestational diabetes mellitus. 80 women were included in the study, including the control group. The study duration was 12 months and the study was completed.

Detailed description

In the cohort study, the study group (GDM group) consisted of 40 pregnant women diagnosed with GDM between 24-28 weeks of gestation with a 2-hour 75-g oral glucose tolerance test (OGTT). While 11 women in the GDM group received insulin treatment, 29 of them provided blood sugar regulation with diet. The 75-g OGTT tests of the 40 pregnant women in the control group were considered normoglycemic while matching with the study group in terms of age, BMI and gestational weeks, and no complications were observed in the pregnant women in this group. Pregnant women with preeclampsia, chronic hypertension, pre-gestational diabetes mellitus, any acute or chronic disease, premature birth, premature rupture of membranes (PPROM), fetal structural or chromosomal anomalies, multiple pregnancies and fetal growth restriction were not included in the study. The ELISA method determined Serum IRAP levels. Serum IRAP levels of pregnant women were measured with enzyme-linked immunosorbent assay. Serum levels of IRAP marker were compared between the groups.

MeasureTime frameDescription
Comparison of serum IRAP levelsup to 1 yearComparison of serum IRAP levels measured during the assessment between pregnant women diagnosed with gestational diabetes mellitus (GDM) based on a 75-gram OGTT performed at 24-28 weeks of gestation and normoglycemic pregnant women.
Evaluation of serum in the pregnant women at 24-28 weeks in ng/ml.up to 1 yearFor IRAP measurements, blood samples taken between weeks 24 and 28 were centrifuged and the serum was separated and stored at -80 ° C until the day of the study. On the day of the study, all samples were thawed at the same time and included in the study.
