Background. The concentration of reduced (GSH), oxidized (GSSG) and total (GSH + GSSG) glutathione, the level of malondialdehyde (MDA), and the general antioxidant activity (GAA) was determined in blood plasma and cervicovaginal washing fluid of pregnant women infected and non-infected with human papilloma virus (HPV). Materials and methods. The population of 213 pregnant women visiting one of the Centers of the Central Outpatient Clinic of Vilnius (Lithuania) in 2008–2010 was included in the study. These women were examined for HPV infection and its type. The tests were performed in the first and third trimesters of pregnancy in blood plasma and cervicovaginal washing fluid. The MDA level was tested by the thiobarbituric acid assay. The amount of glutathione forms was determined using a recycling system with 5,5’-dithiobis 2-nitrobenzoic acid and glutathione reductase. General antioxidant activity (GAA) was measured by Tween 80 oxidation in a specific test. All parameters were analyzed spectrophotometrically. Results. The concentration of all glutathione forms and GAA reduced during pregnancy, while the MDA level was enhanced in the blood plasma of all women included in the analysis. Only two of these parameters changed in the cervicovaginal washing fluid. No significant change of GAA was determined comparing groups of women while considering HPV infection. The GSH / GSSG ratio significantly increased in HPV-negative and decreased in HPV-positive women. While comparing HPV-positive and HPV-negative women of similar age, no significant difference of any parameter was found in cervicovaginal washing fluid and in blood plasma in the third trimester. In the first trimester the GSSG level was significantly lower, the GSH level was higher, and the GSH / GSSG ratio was twice higher in HPV-infected women. All pregnant women were compared with non-pregnant women to confirm the influence of pregnancy on the MDA level. In the first trimester, this parameter for pregnant women was close to that of non-pregnant women, while with the developing pregnancy the MDA level increased 1.6 times. No significant difference in the parameter was determined for pregnant women with HPV infection. Conclusions. A decrease of GSH concentration and an increase of MDA level in blood plasma with the development of pregnancy confirmed the presence of a general oxidative stress. The lower levels of GSH and GSH + GSSG in the cervicovaginal washing fluid, if to compare the two trimesters of pregnancy, can be considered as markers of a local oxidative stress. HPV infection depressed the antioxidative system in general and did not affect it at the local level. Systemic oxidative stress, rather than HPV infection, influenced the lipid peroxidation process during pregnancy. The level of MDA is recommended to be tested also during a normal pregnancy, although this parameter should not be considered as an additional biomarker of cervical carcinoma risk. Changes of the antioxidative system variables could induce a deep oxidative imbalance during a pathological pregnancy, and oxidative stress might cause a persistent HPV infection, suggesting the importance of the additional screening of HPV-infected women after delivery.

Objective: In our study, the results of oral glucose tolerance test (OGTT) and other hemogram parameters of pregnant women with and without gestational diabetes mellitus (GDM) were compared. The aim of our study is to investigate the benefit of these parameters in predicting GDM risk. Material and Method: The study was planned as a descriptive, retrospective and cross-sectional study. It was included 218 pregnant women who applied to the Gynecology and Obstetrics Clinic of Amasya Sabuncuoğlu Şerefeddin Training and Research Hospital between January 01, 2019 and January 31, 2020. It was examined complete blood count parameters, ultrasound findings, complete urinalysis, first trimester blood glucose, body mass index, age, and gravide parameters the patients we included in the study. The results were analyzed retrospectively and was evaluated the statistical significance relationship with gestational diabetes. Results: There was no statistically significant difference in age, body mass index (BMI), obesity status and number of gravida between the pregnant women who were examined and those without GDM (p> 0.05). The hemoglobin, platelet count, mean platelet volume (MPV), mean corpuscular volume (MCV), mean corpuscular hemoglobine (MCH), and mean corpuscular hemoglobin concentration (MCHC) values, and neutrophil, lymphocyte, monocyte and basophil counts, urine density and femur length were statistically significant. There was no difference (p> 0.05). No statistically significant difference was found in terms of neutrophile lymphocyte ratio (NLR), neutrophile monocyte ratio (NMR), platelet lymphocyte ratio (PLR), monocyte eosinophil ratio (MER), platelet MPV ratio (PMPVR), and platelet neutrophile ratio (PNR) values (p> 0.05) Conclusion: HbA1c, hematocrit and blood glucose in the first trimester may be predictors of GDM. In addition, we think that further studies are needed in a prospective design in more patients in terms of others parameters.

Background and objective: Previous studies did not draw a definitive conclusion about the influence of the role of deep endometriosis (DE) and ovarian endometrioma (OE) as risk factor for developing adverse perinatal outcomes in patients affected by endometriosis. This study aimed to investigate if adverse fetal and maternal outcomes, and in particular the incidence of small for gestational age (SGA) infants, are different in pregnant women with OE versus pregnant women with DE without OE. Material and methods: This study was based on a retrospective analysis of a database collected prospectively. The population included in the study was divided into three groups: patients with OE, patients with DE without concomitant OE, and patients without endometriosis (controls). The controls were matched on the basis of age and parity. Demographic data at baseline and pregnancy outcomes were recorded. Results: There was no statistically significant difference in first trimester levels of PAPP-A, first and mid-pregnancy trimester mean Uterine Artery Doppler pulsatile index, estimated fetal weight centile, and SGA fetuses’ prevalence for patients with OE, and those with DE without OE in comparison to health women; moreover, there was no statistically significant difference with regard to SGA birth prevalence, prevalence of preeclampsia, and five-minute Apgar score between these three groups. Conclusions: The specific presence of OE or DE in pregnant women does not seem to be associated with an increased risk of delivering an SGA infant. These data seem to suggest that patients with endometriosis should be treated in pregnancy as the general population, thus not needing a closer monitoring.

Background: Preeclampsia is a multi system disorder with placenta as the organ of origin and maternal endothelium being the organ of target.  According to recent studies, the cell free haemoglobin induces oxidative stress mediated damage to the blood placenta barrier with consequently elevated levels of HbF in maternal blood. Alpha 1 microglobulin is an endogenous protein with antioxidant property, present in elevated levels in maternal blood in response to oxidative stress. This fact forms the basis for our study. The objective of the present study was to establish association between high levels of fetal hemoglobin and alpha 1 microglobulin in plasma of pregnant women between 10 to 16 weeks of gestational age and subsequent development of preeclampsia.Methods: This was a prospective cohort study undertaken in the Department of Obstetrics and Gynaecology, ISO -KGH, between December 2016 to November 2017. A total of 100 pregnant women were included in the study after getting informed written consent. Both primigravida and multigravida, belonging to age group of 20 to 35 years (singleton/ multiple) between 10 to 16 weeks GA and with BMI between 16 to 35 kg/m2 were included in the study. A woman with Diabetes mellitus, Hypertension, Renal disease, Epilepsy and Vascular disorders were excluded from the study.Results: The cut off value for alpha 1 microglobulin was 1.86ng/ml and the cut off value of fetal haemoglobin was 1.92ng/ml above which the pregnant women develop preeclampsia.Conclusions: Higher values of fetal hemoglobin and alpha 1 microglobulin in pregnant women between 10 to 16 weeks gestational age positively correlates with development of preeclampsia in those women.

Abstract Background This study was aimed at determining the levels of serum adiponectin, leptin, resistin, visfatin and lipids during the first trimester in pregnant women and to evaluate the relationship between these biochemical markers and preeclampsia (PE). Available evidence point to changes in the levels of these adipokines in PE hence this study examined the potential of using these biomarkers in the prediction of the disease. Methods This was a case-control study which compared first trimester serum biochemical and anthropometric parameters in pregnant women who subsequently developed PE and those who did not. Blood pressure and urine protein were determined after 20 weeks of gestation and diagnosis of PE performed according to the guidelines of the American Heart Association. Results There was no significant difference (p > 0.05) in the lipid profile with the exception of HDL cholesterol which was significantly lower (p = 0.043) in the PE group compared to the normotensive group. There were, however, significant differences (p <  0.05) in the adipokines between the PE group and those without PE. Analyses of area under the receiver operating characteristic curves (AUCs) for the adipokines, showed their ability to correctly predict PE even after controlling for body mass index (BMI) and family history of hypertension. Conclusion Adiponectin, leptin, resistin and visfatin were found to be significant predictors of PE, with resistin being the best predictor after controlling for BMI. However, adiponectin was the best predictor after controlling for BMI, age, parity and family history of diabetes and preeclmapsia.

Pregnancy is a hypercoagulable state associated with an increased risk of venous thrombosis. Calibrated automated thrombogram (CAT) is a test to monitor the thrombin generation (TG), a laboratory marker of thrombosis risk, and increases during normal pregnancy, but it is still unclear whether TG is related to the use of insulin in pregnant women with gestational diabetes mellitus (GDM). We performed thrombin generation by CAT on 135 normal pregnant women, including 43 in first trimester, 32 in second trimester, 60 in third trimester, respectively; 68 pregnant women with GDM were also enrolled, 19 patients with GDM using insulin to control blood glucose and 49 patients control their blood glucose through diet and exercise with noninsulin treatment. The overall CAT parameters were calculated using descriptive statistics method with mean ± standard deviation. Mean endogenous thrombin potential, peak thrombin generation, and StartTail time increased significantly with the pregnancy. There was no significant difference in TG test parameters except StartTail time( P = .003) in insulin-treated GDM group when compared to those without insulin in the GDM group. The normal ranges for CAT parameters in pregnant women were determined. Thrombin generation increased significantly in first trimester and remains stable in second and third trimester. The use of insulin in patient with GDM did not affect thrombin generation test. Our study helps to establish the reference range of thrombin generation in Chinese normal pregnant population and provide more basis to predict the risk of thrombus complicating during pregnancy.

The effect of dietary supplementation of Cu and Zn on semen quality parameters and certain bio-chemicals parameters were evaluated in Murrah bulls. Twelve mature Murrah bulls (4-6 years of age) were divided into three groups (n=4) T1, T2, and T3 based on semen volume and concentration and were fed as per ICAR standard (2013). However, the animals were supplemented with 0%, 25%, and 50% Cu and Zn above the basal diet in T1, T2 and T3 groups, respectively for 180 days. Quantitative and qualitative characteristics of semen, blood and seminal plasma antioxidant status, blood and semen minerals (Cu, Zn, Ca and Mn) were determined in experimental Murrah bulls. Semen ejaculate volume (mL) increased in T2 and T3 while sperm concentration (million/mL), intact acrosome (%), HOST reacted spermatozoa (%) increased in T3 group compared to T1 and T2 groups. No difference was observed in mass motility, pH, live spermatozoa (%) in semen sexual behaviour except dismounting time which was decreased in T3 than T1 and T2 (plessthan0.05). SOD activity in blood plasma and LPO activity decreased in seminal plasma in both T2 and T3 groups than T1, whereas catalase activity did not show any significant difference. Cu and Zn supplementation in T2 group improved plessthan0.05) Zn level in blood and seminal plasma and Cu level in blood plasma only, but not in seminal plasma. Therefore, it can be concluded that supplementation of Zn and Cu at 50% above the recommended levels of ICAR (2013) improved the qualitative and quantitative attributes of semen in Murrah bulls.

The state of the blood antioxidant system in the patients presenting with acromegaly. The objective of the present study was to evaluate the total antioxidant activity (TAA) of blood plasma, the levels of non-protein thiols and 2-thyobarbituric acid-active products (TBA-AP), superoxide dismutase (SOD) and catalase (CAT) activities as well as ceruloplasmin (CP) level in the patients presenting with acromegaly. It was shown that plasma TAA and SOD activity in this patients was on the average 20 and 30% lower respectively than in the control subjects. At the same time, the TBA-AP and CP levels increased by 50 and 40% respectively. These data suggest the development of oxidative stress in the acromegalic patients.

Objective.To determine plasma markers of oxidative stress during the second and third trimester of pregnancy in patients with gestational diabetes mellitus (GDM).Study Design.We conducted a prospective nested case-control study involving 400 pregnant women, 22 of whom developed GDM. As control group, 30 normal pregnant women were chosen randomly. Plasma samples were analyzed for 8-iso-prostaglandin F2α(8-iso-PGF2α), advanced oxidative protein products (AOPPs), protein carbonyl (PCO), glutathione peroxidase-3 (GPX-3), and paraoxonase-1 (PON1) at 16–20 weeks, 24–28 weeks, and 32–36 weeks of gestation.Results.Compared to control subjects, the plasma levels of PCO, AOPPs, and 8-iso-PGF2αwere elevated at 16–20 weeks’ and 32–36 weeks’ gestation in GDM. There was no significant difference in PCO and 8-iso-PGF2αat 24–28 weeks in GDM. GPX-3 was statistically significantly increased at 16–20 weeks and 32–36 weeks in GDM. PON1 reduced in patients with GDM. No significant differences were found at 24–28 and 32–36 weeks between the GDM and control groups. In GDM, PCO, AOPPs, and 8-iso-PGF2αlevels were higher and GPX-3 and PON1 levels were lower in the second than the third trimester.Conclusion.Oxidation status increased in GDM, especially protein oxidation, which may contribute to the pathogenesis of GDM.

Summary Background: Oxidative stress is thought to be a major contributor to complications during pregnancy, for example preeclampsia. However, reports regarding prooxidant-antioxidant balance in uncomplicated pregnancy are inconsistent. In this study, we aimed to compare the levels of oxidative stress in non-pregnant women with apparently normal pregnant women during the first trimester and at delivery. Methods: An assay for the determination of prooxidant-antioxidant balance (PAB) was used in this study, in which the prooxidant burden and the antioxidant capacity were measured simultaneously in a single assay. The levels of oxidative stress were determined in 85 non-pregnant and 64 primigravid pregnant women. Results: Demographic data and biochemical indices did not differ significantly between the groups. Differences between PAB values were significant based on one-way ANOVA analysis (P<0.001). Using a post hoc test, we observed a statistically significant increase in PAB values during the first trimester and last trimester (P<0.001). Conclusions: Normal pregnancy is associated with a change in the measure of redox status, as assessed by the PAB assay.
