Background and Objectives: Gestational diabetes mellitus (GDM) may impact both maternal and fetal/neonatal health. The identification of prognostic indicators for GDM may improve risk assessment and selection of patient for intensive monitoring. The aim of this study was to find potential predictors of adverse pregnancy outcome in GDM and normoglycemic patients by comparing the levels of different biochemical parameters and the values of blood cell count (BCC) between GDM and normoglycemic patients and between patients with adverse and good outcome. Materials and Methods: Prospective clinical study included 49 patients with GDM (study group) and 44 healthy pregnant women (control group) who underwent oral glucose tolerance test (OGTT) at gestational age of 24–28 weeks. At the time of OGTT peripheral blood was taken for the determination of glucose levels, insulin, glycated hemoglobin, lipid status, homeostatic model assessment, BCC, iron and zinc metabolism, liver function, kidney function and inflammatory status. Each group was divided into two subgroups—normal and poor pregnancy outcome. Results: Higher RBC, hemoglobin concentration, hematocrit value, fasting glucose, uric acid and fibrinogen were found in GDM patients compared to control group. In GDM patients with poor pregnancy outcome values of fibrinogen, ALT, sedimentation rate, granulocyte and total leukocyte counts were elevated, while the serum level of zinc was significantly lower. Higher level of fibrinogen was found in normoglycemic patients with adverse pregnancy outcomes. ROC curve was constructed in order to assess fibrinogen’s biomarker potential. The established AUC value for diagnostic ROC was 0.816 (p < 0.001, 95% CI 0.691–0.941), while the AUC value for assessing fibrinogen’s potential to predict poor pregnancy outcome in GDM was 0.751 (p = 0.0096, 95% CI 0.561–0.941). Conclusions: The results of our study demonstrated that the best prognostic potential in GDM showed inflammation related parameters, identifying fibrinogen as a parameter with both diagnostic and prognostic ability. © 2024 by the authors.

Abstract: Gestational diabetes mellitus (GDM) is a risk factor for both mother and fetus/neonate during and after the pregnancy. Inconsistent protocols and cumbersome screening procedures warrant the search for new and easily accessible biomarkers. We investigated a potential of serum N-glycome to differentiate between healthy pregnant women (n = 49) and women with GDM (n = 53) using a lectin-based microarray and studied the correlation between the obtained data and parameters of glucose and lipid metabolism. Four out of 15 lectins used were able to detect the differences between the control and GDM groups in fucosylation, terminal galactose/N-acetylglucosamine (Gal/GlcNAc), presence of Galα1,4Galβ1,4Glc (Gb3 antigen), and terminal α2,3-sialylation with AUC values above 60%. An increase in the Gb3 antigen and α2,3-sialylation correlated positively with GDM, whereas the amount of fucosylated glycans correlated negatively with the content of terminal Gal/GlcNAc. The content of GlcNAc oligomers correlated with the highest number of blood analytes, indices, and demographic characteristics, but failed to discriminate between the groups. The presence of terminal Gal residues correlated positively with the glucose levels and negatively with the LDL levels in the non-GDM group only. The results suggest fucosylation, terminal galactosylation, and the presence of Gb3 antigen as prediction markers of GDM. © Pleiades Publishing, Ltd. 2024.

Introduction. Invasive mole, a form of gestational trophoblastic neoplasia (GTN), is defined as penetration of molar tissue into the myometrium and/or presence of extrauterine metastases. An invasive mole arising from a complete hydatidiform mole is more common than an invasive mole arising from the partial hydatidiform mole. Dilatation and uterine evacuation and/or curettage (D&E/C) is the first step in managing molar pregnancy. Uterine perforation is the most serious complication of this procedure. A less common one is the false passage. Case report. The first case report describes a 47-year-old woman who was referred to our Clinic under the suspicion of GTN, with elevated serum beta human chorionic gonadotropin (beta hCG) levels. Intraoperatively, devitalized ovular tissue arising from the uterine perforation was observed. Histopathological exam (HPE) of tissue obtained from hysterectomy confirmed an invasive mole as a result of uterine perforation made during D&E/C. The second patient, a 32-year-old woman with vaginal bleeding, nausea, and high levels of serum beta hCG levels was admitted to our Clinic. After four D&E/C, and persistently high levels of serum beta hCG levels, explorative laparotomy has been performed. A false passage created during D&E/C with necrotic and molar tissue was observed. The partial hydatidiform mole was confirmed by the HPE. Conclusion. This is the second reported case in the literature of postmolar GTN as a result of iatrogenic perforation of the uterus, and also the first described case of postmolar GTN arising from a false passage, created as an iatrogenic complication of D&E/C. A national survey of iatrogenic events during the treatment of gestational trophoblastic disaeses is needed since these events could completely change the therapeutic strategies in managing these diseases. © 2022 Inst.
