[Show abstract][Hide abstract] ABSTRACT: Reactive oxygen species (ROS) are produced in many metabolic and physiologic processes. Antioxidative mechanisms remove these harmful species. Our aim was to assess whether serum total antioxidant capacity and total oxidant status altered during first trimester pregnancies with vaginal bleeding.
In this cross-sectional study, A group of pregnant women at less than 10 weeks of gestation with vaginal bleeding (n=25) and a control group of healthy pregnancies with similar characteristics (n=25) were included. All of the patients in the two groups were matched for age, gestational age and body mass index. Serum total antioxidant capacity and total oxidant status levels were determined using a Hitachi 912 analyzer and compared between the two groups.
Characteristics, including maternal age, parity, and gestational age were similar between the two groups. Serum total antioxidant capacity levels were significantly lower in the women with vaginal bleeding than in control women (1.16 ± 0.20 vs. 1.77 ± 0.08 mmol Trolox Equiv./L; p=0.001), whereas higher total oxidant status measurements were found in women with vaginal bleeding compared to the control group (4.01 ± 0.20 vs. 2.57 ± 0.65 µmol H2O2 Equiv./L; p=0.001).
Increased total oxidant status might be involved in the pathophysiology of vaginal bleeding during early first trimester pregnancies.

[Show abstract][Hide abstract] ABSTRACT: Objective:
The aim was to determine whether inherited thrombophilia increases the risk of pre-eclampsia (PE) or interferes with its clinical course.
Material and methods:
We included 50 patients with severe PE and 50 healthy pregnant women. Patients were evaluated for inherited thrombophilia.
Fourteen patients in the study group was factor V Leiden (FVL) carrier while it was 12% in the control group. In women with PE, FVL and other inherited thrombophilic factors were not more prevalent than in the controls.
The present study failed to demonstrate an association between the inherited thrombophilias and PE.

In 13 cases, intrauterine death of one fetus was found during the first trimester; in 25 cases, it was found after the first trimester. Obstetric complications and fibrinogen levels were compared. There were no significant differences in the number of preterm delivery, preeclampsia, and intrauterine growth restriction and there were significant differences in gestational age at delivery and birth weight between groups. Coagulation disorders did not occur. The risk for adverse pregnancy outcomes with a single fetal death during and after the first trimester is similar.
[Show abstract][Hide abstract] ABSTRACT: Our primary aim was to investigate whether N-terminal pro-brain natriuretic peptide (NT-proBNP) increases in adolescent with polycystic ovary syndrome (PCOS) compared with healthy controls and secondary aim was to determine whether metabolic and hormonal differences exist between groups.
In this cross-sectional study, 25 adolescent patients with PCOS and 25 normal ovulatory control not suffering from PCOS were involved in the study. Fasting serum NT-proBNP, C-reactive protein (CRP), homocystein, insulin levels and biochemical and hormonal parameters were measured.
Serum NT-proBNP was not significantly different in PCOS subjects (0.62 ± 0.80 vs 1.12 ± 1.51 ng/mL, p = 0.154). The mean serum fasting insulin levels (22.64 ± 10.51 vs 13.32 ± 3.97 mIU/mL, p = 0.001) and Homeostasis Model Assessment Insulin-Resistance Index (HOMA-IR) levels (5.16 ± 1.81 vs 2.97 ± 0.89, p = 0.001) were significantly high in the study group. The median serum CRP levels were not significantly different between groups (1 [1-12] vs 1 [1-19] g/dL, p = 0.286).
The present study demonstrated that the levels of BNP, CRP and homocystein were not different in PCOS subjects. Serum insulin levels and HOMA-IR were significantly higher in PCOS subjects. Possible serum markers for PCOS-related metabolic abnormalities and cardiovascular events, may not present in the adolescent years.
[Show abstract][Hide abstract] ABSTRACT: Early ovarian hyperstimulation syndrome is an acute consequence of the excessive ovarian response to gonadotropin stimulation and has a higher risk of preclinical miscarriage. We reported a case of ongoing twin pregnancy in an obese patient with polycystic ovary disease, critical early ovarian hyperstimulation syndrome and liver dysfunction. This case demonstrates the severity of gastrointestinal symptoms and liver dysfunction that can occur with ovarian hyperstimulation syndrome. We tried to focus on the pathogenesis of liver dysfunction, which is a rare and life-threatening complication and suggested strategies to prevent similar cases in the future.

[Show abstract][Hide abstract] ABSTRACT: We aimed to investigate possible alterations in circulating levels of the high sensitivity (hs)-C-reactive protein (CRP) reflecting tissue inflammation in patients who conceived with an intrauterine device (IUD) and in pregnancies after IUD removal in early pregnancy.
Serum hs-CRP levels were measured in 30 pregnant women with retained IUD and 18 pregnancies after IUD removal in early pregnancy. Rates of total miscarriage, premature rupture of membranes (PROMs), low birth weight, placental abruption, and preterm delivery were also documented.
Serum levels of CRP were significantly higher in pregnant women with retained IUD than pregnancies with removed IUD. Total miscarriage, PROMs, placental abruption, and preterm delivery rates were significantly higher in pregnant women with retained IUD compared with pregnancies after IUD removal in early pregnancy.
Serum CRP concentrations are increased in pregnant women with retained IUD. Our findings also suggest that the pregnancies with retained IUDs that are not removed are at increased risk for adverse pregnancy outcomes.
