Decreased fetal thymus size at 24weeks gestation by ultrasound measurement in gestational diabetes mellitus fetal thymus examination for diabetes

AimThis study aimed to evaluate the difference in fetal thymus diameter, which we measured ultrasonographically, between the healthy pregnant group and the pregnant group with gestational diabetes.MethodFetal thymus and thymus/thorax ratio parameters were assessed in this case–control study. Patients were examined in two groups. They included 49 diabetics (study group) women and 71 nondiabetic (control group). We performed a binary logistic regression analysis to determine the predictive value of ultrasonographic measurements. We completed the receiver curve characteristic analysis to evaluate the cut‐off thymus diameter.ResultsThe median age of pregnant women was 27. Thymus diameter and thymus‐thorax ratio were smaller in fetuses of diabetic mothers than in the nondiabetic group (p
