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.

Background and Objectives: Inherited thrombophilia (IT) increases the risk of adverse pregnancy outcomes, but the benefit of low-molecular-weight heparin (LMWH) prophylaxis remains debated. This study aimed evaluate the effect of LMWH by analyzing outcomes in women with IT who received LMWH versus those who did not and also compare pregnancy complication rates before and after inherited thrombophilia diagnosis. Materials and Methods: We conducted a retrospective case–control study including 276 pregnant women with inherited thrombophilia and prior pregnancy complications and 276 healthy pregnant controls on delivery. The main outcome was the incidence of complications: preterm rupture of membranes, oligohydramnios, fetal growth restriction, preterm delivery, stillbirth, HELLP syndrome, gestational hypertension, deep vein thrombosis, and recurrent pregnancy loss. The effect of LMWH was assessed by comparing complication rates among inherited thrombophilia patients who received therapy versus those who did not. Results: Women with IT were older, had higher BMI, delivered earlier, and had neonates with lower birth weight compared to controls. In current pregnancies, LMWH was associated with reduced rates of preterm delivery, fetal growth restriction, gestational hypertension, and recurrent pregnancy loss, especially in factor V Leiden carriers. LMWH had little effect on low-risk genotypes and was not independently associated with outcome reduction. Conclusions: LMWH prophylaxis should be reserved for high-risk women with IT. Routine use in all IT pregnancies is not justified and may cause unnecessary risks and costs. Early screening, risk stratification, and individualized care are essential to optimize outcomes.

Insulin resistance is believed to be an integral component of the polycystic ovary syndrome (PCOS). Beta (ß) cell dysfunction is also found in PCOS. In the study, we determined the influence of age, body mass index (BMI), and waist-to-hip ratio (WHR) on insulin response to oral glucose load (OGTT) and on insulin sensitivity (Si) and ß-cell function in young women with PCOS. One hundred fourteen patients with PCOS and 41 controls with normal basal plasma glucose were studied. A 75-g OGTT was performed to determine glucose tolerance and insulin response. Insulin sensitivity and ß-cell function were studied using a modified frequently sampled IV glucose tolerance test (FISGTT) to determine the acute insulin response (AIR_G), as well as S_i by minimal model analysis. S_i was decreased in PCOS women (2.49 0.18 vs. 3.41 ± 0.36, ), but no difference in AIR_G existed between the PCOS and control group (75.1 ± 4.6 vs. 63.4 ± 4.6, ). BMI and WHR correlated negatively with S_i (r = −0.43; r = −0.289, , respectively), but not with AIR_G (r = 0.116; r = −0.02, , respectively). Increasing age correlated negatively with AIR_G (r = −0.285, ). There was a significant interaction between disease (PCOS), BMI, and WHR on S_i as well as between age and PCOS on AIR_G. Thus, patients below the age of 25 with PCOS showed enhanced AIR_G (89.5 ± 7.1 vs. 65.1 ± 6.7, ) and decreased S_i (2.43 ± 0.25 vs. 4.52 ± 0.62, ) compared to age-matched controls. In conclusion, these data suggest that not all patients with PCOS have basal and stimulated hyperinsulinemia, insulin resistance, and impaired glucose tolerance. Based on these data in young PCOS subjects, the development of insulin resistance and T2DM may be prevented with appropriate treatment strategies.
