Background/Aim. Preeclampsia (PE) is a multisystemic syndrome that complicates 5?8% of all pregnancies. The aim of this study was to evaluate the biochemical parameters of oxidative stress in the first trimester of pregnancy in patients with preeclampsia, with the purpose of comparing the level of oxidative stress with normal pregnancy. Methods. The study was conducted as a prospective study. It included totally 107 pregnant women divided into two groups. In the study group (n = 33) there were women who developed preeclampsia in the current pregnancy. The control group (n = 74) included healthy pregnant women. Blood samples were taken between 11th and 14th weeks of gestation, and the values of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and total antioxidant status (TAS) were determined in serum by enzymatic colorimetric methods. Results. The values of SOD and GHS-Px were statistically higher in the study group, while the values of TAS were statistically higher in the control group. The level of TAS inversely correlated with GSH-Px and SOD, but there is no statistically significant correlation between GSHPx and SOD in the study group. Conclusion. The results of this study suggest a higher level of oxidative stress in the first trimester of pregnancy with preeclampsia, which may indicate that the initiation and development of pathophysiological processes underlying preeclampsia start much earlier than the clinical syndrome exhibit.

Abstract Background The aim of this study was to evaluate the markers of oxidative stress (OS), as well as the magnesium (Mg) concentration, pregnancy-associated plasma protein A (PAPP-A) and human chorionic gonadotropin (β-hCG) values in patients with previous recurrent miscarriages, with the purpose of comparing the level of OS with normal pregnancy. Methods The study was conducted as a prospective study, which included a total of 95 pregnant women divided into two groups. In the study group (n = 35), there were women with at least three consecutive previous miscarriages. The control group (n = 60) consisted of healthy pregnant women without previous miscarriages and complications in pregnancy. Blood samples were taken between the 11th and 14th weeks of gestation, and the values of superoxide dismutase (SOD-1), glutathione peroxidase (GSH-Px) and total antioxidant status (TAS) in the serum, as well as the Mg concentration, PAPP-A and β-hCG values were determined. Results The values of SOD and GHS-Px were statistically higher in the study group, while the values of TAS were statistically significantly higher in the control group. The values of the Mg concentration were statistically significantly higher in the control group, while the values of β-hCG were statistically significantly higher in the study group. When the study group was divided into subgroups according to the outcome of pregnancy, there were statistical differences in the level of GSH-Px, SOD between miscarriages and the term delivery group, as well as in the Mg concentration between miscarriages and the term delivery group and between the term and preterm delivery groups. Higher values of SOD and GHS-Px, and lower values of TAS and Mg concentration could be used as markers for the prediction of spontaneous miscarriages. Conclusions The results of this research indicated higher OS and exhaustion of antioxidant mechanisms in early pregnancy in a group with recurrent miscarriages. Also, lower values of serum Mg concentration could be one of the markers for the prediction of spontaneous miscarriages.

Objective: To measure the distribution of TPO-Ab positivity and to observe the effect of thyroid peroxidase positivity on thyroid function during first trimester in normal pregnancy. Method: A cross sectional among 120 subjects were taken in this study and divided into control and study groups. Control group (Group A) consisted of 60 healthy non pregnant women age ranged between 20 to 35 years. Study group (Group B) consisted of 60 normal pregnant women of same age range. Group B was further subdivided into group B1 and group B2according to the level of TPO-Ab. Group B1 consisted of TPO-Ab positive pregnant women and group B2 consisted of TPO- Ab negative pregnant women. Control group was selected from personal contacts and study group from Out Patient Department (OPD) of Obstetrics and Gynecology of Sir Salimullah Medical College and Mitford Hospital. For assessment of thyroid function, serum free thyroxine (FT4), thyroid stimulating hormone (TSH) were measured. Serum FT4, TSH were measured by Enzyme link immunosorbant (ELISA) method. Again, serum TPO-Ab of total study population and hCG of all the pregnant women were measured. Serum TPO-Ab by Micro particle Enzyme Immunoassay (MEIA) method and hCG was estimated by ELISA. Statistical analysis was done by SPSS version 17. Results: In this study, serum FT4 and was significantly (P<0.001) higher and TSH level was significantly (P<0.001) lower in normal pregnant women during 1st trimester in comparison to those of non pregnant women. Again, 18% of pregnant women showed TPO-Ab positivity. However, serum FT4 level was significantly (P<0.001) lower whereas, TSH level was significantly (p<0.001) higher in TPO-Ab positive pregnant women in comparison to those of TPO-Ab negative pregnant women. Conclusion: TPO-Ab positivity increases during 1st trimester of normal pregnancy which decreases the hyper functional state of thyroid hormones. So, thyroid screening should be done routinely during pregnancy. DOI: http://dx.doi.org/10.3329/updcj.v4i1.21160 Update Dent. Coll. j: 2014; 4 (1): 15-20

Introduction: In order to evaluate the value of the Placenta Growth Factor (PlGF) in the developing the gestational complications during multiple pregnancies, a study of this indicator in serum of 320 pregnant women with multiple pregnancies in the first trimester, as well as 40 pregnant women with single pregnancy, constituted a control group. The aim: of the study is to investigate the effect of the placental growth factors on gestational process during multiple pregnancies. Materials and methods: A prospective study of maternity pregnancy in 320 females with multiple pregnancies was conducted, which comprised the main group of the subjects and 40 healthy women with unipolar pregnancy. The level of PlGF in serum was determined by solid phase enzyme analysis using monoclonal antibody sets in the first trimester of pregnancy. Indicators of the hemostasis system (vascular thrombocyte and coagulation link) were evaluated according to generally accepted methods. Dopplerometry of placental and fetal blood flow was performed in uterine arteries, arteries and umbilical cord veins, middle cerebral artery of the fetus. Results: Women with multiple pregnancies are at the risk of gestational complications - premature births in 67.8% (p <0.01), feto placental dysfunction, pre eclampsia - in 17.5% (p <0.05) cases. The revealed violations of the vascular thrombocyte and coagulation homeostasis in the first trimester of pregnancy are the main risk factors for early premature abortion. It has been shown that the low level of placental growth factor in serum of pregnant women with multiple pregnancies in the case of premature labor, feto placental dysfunction and pre-eclampsia (111.23 ± 8.4, 203.24 ± 6.4 and 305.86 ± 7.4 pg / ml) compared with the corresponding indicators for single-pregnancy (418.2 ± 10.4 pg / ml) is a prognostic marker for the development of gestational complications. Conclusions: Timely medical correction of gestational complications during multiple pregnancies with the use of micronized progesterone, low molecular weight heparins, angio protectants allowed prolonging the pregnancy with mono choric type of placentation by 3.2 weeks (up to 34.2 ± 2.4 weeks), and in the case of dichoric twins - to full-term pregnancy.

The advantage in response of Th2 over Th1 is observed in normal pregnancy in peripheral blood. A disturbance of this balance can lead to symptoms of miscarriage and pregnancy loss. The aim of this study was to evaluate the pro- and anti-inflammatory cytokines in sera of women who were diagnosed with missed miscarriage in the first trimester and to compare this systemic immune response to the response in women with normal pregnancy. The study group consisted of 61 patients diagnosed with missed miscarriage. In total, 19 healthy women with uncomplicated first trimester created the control group. Cytokines were determined in the maternal serum by ELISA. The analysis included INF-γ, TNF-α, Il-1β, Il-4, Il-5, Il-6, Il-9, Il-10, Il-13 and TGF-β1. Th1 cytokine levels in the study group reached slightly higher values for INF-γ, Il-1β and slightly lower for IL-6 and TNF-α. In turn, Th2 cytokine levels in the study group were slightly higher (Il-9, Il-13), significantly higher (Il4, p = 0.015; Il-5, p = 0.0003) or showed no differences with the control group (Il-10). Slightly lower concentration involved only TGF-β1. Analysis of the correlation between levels of pro- and anti-inflammatory cytokines resulted in some discrepancies, without showing predominance of a specific immune response. The results did not confirm that women with missed miscarriage had an advantage in any type of immune response in comparison to women with normal pregnancy.

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.

AbstractTo investigate the possible effect of abnormal placentation disorders such as preeclampsia (PE), pregnancy induced hypertension (PIH) and intrauterine growth restriction (IUGR) on erythropoietin (EPO) serum concentration in women in the first trimester of pregnancy.A prospective study was performed in a group of pregnant women between 11 and 13A group of 198 analyzed patients was divided into three groups depending on pregnancy outcome: abnormal placentation group (n=30), macrosomia (n=13) and control group (n=155). EPO concentrations between the three groups of patients revealed that they differ significantly (F=15.172, P<0.001). EPO concentration is significantly higher in abnormal placentation patients compared to the control group (P<0.001) and macrosomia group (P=0.004). The most significant increase in EPO concentration was detected within patients with PIH. Also the uterine artery pulsatility index was positively correlated with EPO concentration (P<0.01).First-trimester maternal EPO concentration might be considered as a possible marker of abnormal placentation disorders and should be given more attention in future prospective studies.

And Oxidative Stress

Inflammation and oxidative stress are intrinsically linked to early poor placentation, typical of pregnancies complicated by preeclampsia associated with intrauterine growth restriction (PE-IUGR). Low mitochondrial DNA copy number (mtDNAcn) in peripheral blood constitutes a good peripheral surrogate marker of inflammation and oxidative stress. On these basis, we explored a possible correlation between mtDNAcn in peripheral blood in the first trimester of pregnancy and the PE-IUGR onset. To shed light on this issue, we setup a nested case–control study from a prospective cohort of pregnant women undergoing first-trimester aneuploidies screening. Two groups of patients affected by PE classified according to the clinical phenotype were identified: (1) patients who developed PE-IUGR and (2) patients who developed PE associated with appropriate for gestational age intrauterine fetal growth (PE-AGAf). Controls were women with a physiologic pregnancy matched to cases on the basis of age (±6 months, ratio 2:1). Mitochondrial DNA copy number was quantified using real-time polymerase chain reaction and normalized to nuclear DNA. The median (interquartile range) mtDNAcn in peripheral blood in patients with PE-IUGR (n = 12) and in patients with PE-AGAf (n = 16) was 70 (44-97) and 108 (95-145), respectively ( P = .004). Both these values were significantly lower than that detected in the control group (161[133-183], P < .001). The area under the receiver–operator curve for PE-IUGR and PE-AGAf were 0.94 (95% confidence interval [CI]: 0.88-1.00, P < .001) and 0.81 (95%CI: 0.70-0.91, P < .001), respectively. In conclusion, MtDNAcn in peripheral blood resulted significantly lower both in patients affected by PE-IUGR and in those affected by PE-AGAf when compared to controls. The accuracy of this biomarker resulted particularly good in predicting PE-IUGR.

Objective: To investigate the effect of vitamin D deficiency on the levels of thyroid stimulating hormone (TSH), thyroid peroxidase antibody (TPO-Ab), interleukin-1 (IL-1) and high-sensitivity C-reactive protein (hs-CRP) in pregnant women with early pregnancy complicated by subclinical hypothyroidism. Methods: A total of 172 pregnant women with subclinical hypothyroidism in the first trimester diagnosed and treated in a given hospital from August 2014 to May 2018 were selected, and their levels of vitamin D were determined. Depending on the abnormality of their vitamin D levels, the study participants were divided into two groups: the study group (vitamin D≤20 ng/L) and the control group (vitamin D>20 ng/L). The levels of TSH, TPO-Ab, IL-1 and hsCRP in the two groups were measured. Results: The levels of TSH, hsCRP and TPO-Ab in the study group were significantly higher than those in the control group (P < 0.05). The comparison between the two groups in terms of IL-1 showed no statistically significant difference. Conclusion: Vitamin D deficiency in the first trimester is associated with in an increased level of TSH in the first trimester, thereby aggravating subclinical hypothyroidism. The mechanism may be associated with the impact of vitamin D deficiency on hs-CRP and other body inflammation indicators, as well as on thyroid autoantibodies and other immune indicators, but has no effect on IL-1 levels. doi: https://doi.org/10.12669/pjms.36.6.1982 How to cite this:Zhou X, Li B, Wang C, Li Z.

<p><strong>Introduction:</strong> Most of miscarriage events occurred during the first trimester of pregnancy. Recent studies found the beneficial effects of maternal serum markers to predict pregnancy outcomes. However, study in Indonesian setting was still limited, especially in outpatient setting. The aim of this study was to evaluate serum progesterone and β-hCG measurement  as a beneficial predictor of miscarriage.</p><p><strong>Materials &amp; Methods:</strong> This was a prospective study recruiting outpatients pregnant women in Aceh who seek first medical attention for their pregnancy during January 2013 to January 2015. Serum progesterone and β-hCG level were measured beside routine obstetric procedure. The discrimination attained between miscarriage and non-miscarriage groups of pregnant women at the end of first trimester was evaluated using logistic regression and receiver operating curve analysis.</p><p><strong>Results: </strong>Among 70 pregnant recruited in this study, nineteen of them (27.1%) experienced miscarriage. Serum progesterone level of women in miscarriage group was lower than non-miscarriage group (17.85 (IQR 13.26-21.15) ng/dl vs 33.67 (IQR 21.83-44.14), p&lt;0.001). Serum β-hCG level was also lower in miscarriage group (10 681 (IQR 5 787.5-26 577.5) mIU/ml vs 48 109 (IQR 17 137-93 915) mIU/ml, p=0.001). Single progesterone measurement gave a good predictor ability for miscarriage with 82.2% accuracy, 86.3% sensitivity and 73.7% specificity if 19.5 ng/dl was used as a cut-off point.</p><strong>Conclusion: </strong>Maternal serum progesterone level could be a good predictor for miscarriage during the first trimester of pregnancy. Single β-hCG serum in combination with progesterone serum measurement only had little added value for predicting miscarriage.

Objectives: Evidence suggests that oxidative stress (OS) plays a prominent role in the pathophysiology of pregnancy complications in women. The present study was conducted to determine the levels of OS markers in early pregnancy loss and to compare the results with those in healthy pregnant women. Materials and Methods: A total of 32 women with early pregnancy loss and 32 healthy women in the first trimester of pregnancy, with similar demographic characteristics entered this study as the cases and controls. Serum levels of malondialdehyde (MDA), total antioxidant capacity (TAC), uric acid, and bilirubin levels were determined in both groups. The data obtained were then analyzed and compared between the groups using the independent samples t test and Mann-Whitney U test. Results: The 2 groups matched in terms of personal-demographic characteristics including mother’s age, father’s age, gravidity, and body mass index (BMI). MDA levels increased significantly in the women with spontaneous abortion compared to the healthy pregnant women (4.35±1.47 vs. 3.42±1.68 µM/L; P=0.026) and TAC decreased significantly in the cases compared to the healthy controls (552.34±212.79 vs. 1003.23±1168.68 U/mL; P=0.040). Uric acid and bilirubin levels did not differ between the groups. Conclusions: The results of this study provides further evidence on the effect of increased OS on the incidence of early spontaneous abortion in the first trimester of pregnancy. High serum MDA levels and low TAC during pregnancy were 2 risk factors for spontaneous abortion. The present findings support the hypothesis that OS plays a key role in the etiopathogenesis of spontaneous abortion. Further studies are required for assessing the preventive role of antioxidant therapy in this complication.
