AB  - Introduction: MicroRNAs have a significant role in the pathogenesis of preeclampsia. Circulating microRNAs could represent a potential biomarker for preeclampsia. The aim of this study was to evaluate plasma miR210-3p and miR518b in preeclampsia and healthy pregnancy for the first time by digital droplet PCR (ddPCR). Methods: Thirty-six pregnant women (seventeen healthy pregnancies, nineteen preeclampsia patients) were involved from the Clinic for Gynaecology and Obstetrics “Narodni front” in Belgrade, Serbia. Plasma miR210-3p, miR518b and cel-miR-39 as a spike-in control were measured by ddPCR. Results: MiR518b was significantly elevated in preeclampsia compared to a healthy pregnancy (P = 0.034; 0.302(0.217–0.421) vs. 0.171(0.110–0.266)). MiR210-3p showed no significant difference between the two groups (P = 0.951). The adjustment of miR518b was made for a gestational age and smoking status and the difference between the preeclampsia and healthy pregnancy group was more significant (P = 0.026; 0.300(0.216–0.419) vs. 0.172(0.121–0.245)). Plasma miR-518b was significantly higher in the group of preeclampsia patients with proteinuria above the 75th percentile for the group (P=0.033), in women who smoked (P=0.039), and was positively related to uric acid in preeclampsia (P = 0.018, r = 0.536). Plasma miR518b was able to significantly discriminate between preeclampsia and healthy pregnancy, yielding AUC of 0.712 (95%CI:0.539–0.891), P = 0.028. Conclusions: In this study plasma microRNA were measured for the first time in preeclampsia and healthy pregnancies with ddPCR. Placenta-specific miR-518b could serve as a potential biomarker for discriminating preeclampsia and healthy pregnancy, which should be confirmed on a larger study population. This study has failed to confirm the same potential for miR210-3p.

AB  - We investigated whether gestational diabetes mellitus (GDM) and gestational arterial hypertension (GH) are associated with increased oxidative stress and DNA damage. Study included 3 groups of pregnant women (GDM, GH and control). DNA damage biomarkers (micronuclei MNi, nucleoplasmic bridges NPBs and nuclear buds NBUDs) were assessed by cytokinesis-block micronucleus cytome assay. Oxidative stress levels were evaluated by analyzing malondialdehyde equivalents (TBARS) and 8-hydroxy-2'deoxyguanosine (8-OHdG). Genotoxic effect of methyldopa, drug used to treat GH, was evaluated in in vitro experiment. TBARS levels, MNi, NPBs and NBUDs frequencies were significantly increased in both GDM and GH group. Concentrations of 8-OHdG were significantly higher in GDM than in other groups. Since methyldopa did not affect MNi, NPBs and NBUDs frequencies, nor TBARS and 8-OHdG levels, we concluded that methyldopa has no genotoxic effect. Thus, even when hyperglycemia or hypertension are present only during pregnancy they induce oxidative stress, DNA damage and chromosomal aberrations.
