High Metabolic Demand

INTRODUCTION: Pregnancy is associated with high metabolic demand and increased demand for tissue oxygen. Consequently increased production of reactive oxygen species. This leads in increased oxidative stress and decreases antioxidant status during gestational age of normal pregnant women. Aim: Aim of this study was to evaluate the level of oxidant and antioxidant in 1st and 3rd trimester of normal pregnant women. MATERIAL AND METHODS: The present study included total 150 cases attended ANC Clinic at the department of Gynae LNMC & J K Hospital was screened for the study. Level of MDA was estimated by Jean et al and SOD was Marklund and Marklund. RESULTS: Findings were, that there was signicantly increase in Malondialdehyde levels (p<0.001) and signicantly decrease in superoxide dismutase activities (P<0.001) in 1st and 3rd trimester of normal pregnant women. Conclusion: present study concludes that there was difference in oxidative status due to dynamic changes. During pregnancy oxidative stress is increased and antioxidant decreased that can be fatal to the health of the mother and the fetus. Therefore antioxidant supplements should be prescribed in early pregnancy to prevent the overwhelming of oxidative stress in pregnant females.

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.

ABSTRACT BACKGROUND: Preeclampsia (PE) is a systemic pregnancy-related disorder characterized by hypertension, proteinuria, and edema. Free radicals seem to play an important role in the induction of endothelial dysfunction in PE. AIM: The aim of the present study was to investigate serum levels of nitric oxide (NO), peroxynitrite (ONOO−), paraoxonase (PON-1), malondialdehyde (MDA), and lipid profile in preeclamptic patients compared to the women with normal pregnancy. MATERIALS AND METHODS: A total of 68 pregnant women were recruited. They were divided into two groups - Group A, 40 women were a newly diagnosed with PE and Group B, 28 women with normal pregnancy. Anthropometric measurements including body mass index and blood pressure in accordance with biochemical measurements including NO, ONOO−, PON-1, MDA, and lipid profile were done for preeclamptic pregnant women compared to the controls. RESULTS: Pregnant women with pre-eclampsia illustrated insignificant differences in the age (31.22±2.87) compared to the age of control P > 0.05. There were significant changes in the body mass index (BMI) , type of delivery and smoking status of pregnant women with pre-eclampsia compared to the control P < 0.05. Both systolic and diastolic blood pressures were high in pregnant women with pre-eclampsia compared to the control P < 0.01. PON-1 and NO serum levels were significantly decreased (P < 0.01) while ONOO− and MDA serum levels were significantly increased in PE compared to the women with normal pregnancy. Conclusions: This study concluded that PE is associated with the augmentation of oxidative stress and reduction of endogenous antioxidant capacity regarding PON-1.

Insight Into

Resistin is expressed in human placenta and has been postulated to play a role in regulating energy metabolism in pregnancy. However, changes in serum resistin levels in normal pregnancy and in the setting of pre-eclampsia are far from understood. The purpose of the present study was to clarify the alterations in serum resistin level in normal pregnancy and pre-eclampsia. Blood samples were taken from 28 healthy non-pregnant women, 27 women in the first, 26 in the second and 26 in the third trimesters of normal pregnancy and 25 women with pre-eclampsia. Serum resistin concentrations were determined by using an ELISA, and mean serum resistin levels were compared with one-way ANOVA. Serum resistin levels were not significantly different among non-pregnant women and women in the first and second trimesters of pregnancy (P>0.05 for all). Serum resistin was significantly elevated in the third trimester of normal pregnancy compared with non-pregnant women (P<0.01) and women in the first (P<0.001) and second (P<0.001) trimesters of pregnancy. Serum resistin level was significantly lower in women with pre-eclampsia than women in the third trimester of normal pregnancy (P<0.001), but was comparable with those of non-pregnant women and women in the first and second trimesters of pregnancy (P>0.05 for all). In conclusion, we found an increase in serum resistin in the third trimester of normal pregnancy, but this increase was not present in pre-eclampsia. We postulate that these associations may offer insight into the mechanisms of maternal adaptation to pregnancy and the pathogenesis of pre-eclampsia.

Objective It is unknown whether the heart operates in the ascending or flat portion of the Starling curve during normal pregnancy. Pregnant women do not respond to the passive leg-raising maneuver secondary to mechanical obstruction of the inferior vena cava by the gravid uterus. Our objective was to evaluate if administration of a fluid bolus increases baseline stroke volume (SV) among healthy pregnant patients during the third trimester. Study Design Healthy pregnant women who underwent elective term cesarean sections were included. A noninvasive cardiac output monitor was used to measure hemodynamic variables at baseline and after administration of a 500-mL crystalloid bolus. Results Forty-five women were included in the study. Fluid administration was associated with a statistically significant increase in SV from a baseline value of 71 ± 11 to 90 ± 19 mL (95% confidence interval [CI]: 13.67–21.49; p < 0.01) and a significant decrease in maternal heart rate from a baseline of 87 ± 9 beats per minute to 83 ± 8 after the fluid bolus (95% CI: −6.81 to −2.78; p = 0.03). No changes in peripheral vascular resistances or any other measured hemodynamic parameters were noted with volume expansion. Conclusion In healthy term pregnancy, the heart operates in the ascending portion of the Starling's curve, rendering it fluid responsive.

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.

1. During human pregnancy marked vasodilatation occurs in arterial and venous vascular beds. The mechanisms responsible for this change remain unclear. The contribution of increased nitric oxide activity to vasodilatation associated with pregnancy was determined by examining superficial hand vein responses to NG-monomethyl-l-arginine, an inhibitor of nitric oxide synthase, in post-partum women 24–48 h after delivery when vasodilatation remains at levels present during the third trimester. 2. Seventeen healthy women, 24–48 h post partum, and 13 healthy non-pregnant women were studied. Eight of the post-partum women underwent repeat studies 12–16 weeks after delivery. 3. NG-monomethyl-l-arginine (100 nmol/min) resulted in venoconstriction in non-constricted veins (baseline, 0%; 5 min, 26 ± 9%; 10 min, 14 ± 8%; 15 min, 8 ± 7%; means ± SEM) and noradrenaline-constricted veins (5 min, 30 ± 7%; 10 min, 24 ± 10%; 15 min, 14 ± 11%). No constrictor response to NG-monomethyl-l-arginine was present in the same women 12 weeks post partum (5 min, 1 ± 4%; 10 min, 0 ± 3%; 15 min, 1 ± 4%) or in the non-pregnant control subjects in non-constricted (5 min, 2 ± 3%; 10 min, 4 ± 3%; 15 min, 2 ± 2%) or noradrenaline-constricted veins (Smin, − 2 ± 7%; 10 min, 1 ± 9%; 15 min, − 5 ± 7%). 4. These findings indicate that nitric oxide activity is increased in the immediate post-partum period in venous vasculature, and support the hypothesis that increased nitric oxide activity may be responsible for the vasodilatation observed during normal pregnancy.

Aim To assess the glycaemic profile and glycaemic variation in the second and third trimesters of normal pregnancies. Methodology Healthy pregnant women aged 19–35 years between 24 and 36 weeks of gestation were recruited for ambulatory glucose profile monitoring. A total of 18 women in the second trimester, 15 women in the third trimester and 9 healthy non-pregnant women were recruited providing, respectively, 205 days (19,680 data points), 147 days (14,112 data points) and 100 days (9,600 data points) for analysis. Results Mean blood glucose level was 20.2% lower in the second trimester and 10.6% lower in the third trimester than non-pregnant women (p < 0.001). In pregnancy, it took 15 to 20 minutes more to reach peak postprandial blood glucose levels compared to non-pregnant women (p = 0.003). Glycaemic variability was more in the third trimester (p < 0.001). Conclusion There is tight blood sugar control along with lower mean blood glucose in healthy pregnant women compared to non-pregnant women. Despite this tight glycaemic control, glycaemic variability is higher during pregnancy.

To examine a possible role for endothelin-1 (ET-1) and conversion of big ET-1 to ET-1 in the pathophysiology of pre-eclampsia, we measured plasma levels of ET-1 and big ET-1 in 16 women with pre-eclampsia in the third trimester and compared them with those in 11 age-matched normotensive pregnant women and in 10 age-matched pregnant women with chronic hypertension in the third trimester. The plasma concentrations of ET-1 and big ET-1 in the normotensive pregnant women were significantly lower than those in 16 non-pregnant women with a higher molar ratio of big ET-1 to ET-1 in the former group. The plasma concentrations of ET-1 and big ET-1 in the women with pre-eclampsia, on the other hand, were significantly higher than those in the normotensive pregnant women and the molar ratio of big ET-1 to ET-1 in the former group was less than that in the latter group. In sharp contrast, plasma ET-1 and big ET-1 levels in the pregnant women with chronic hypertension were not significantly different from those in the normotensive pregnant women. When examined after delivery, elevated plasma ET-1 and big ET-1 in the women with pre-eclampsia declined, with restoration of normal blood pressure, to the levels in the normotensive women after parturition. There were no significant differences of the levels of ET-1 and big ET-1 in umbilical venous plasma and simultaneously drawn maternal plasma at cesarean section between normotensive pregnant women and women with pre-eclampsia, respectively. These results suggest that normal pregnancy is associated with decreased plasma concentrations of ET-1 with reduced conversion of big ET-1 to ET-1 in maternal vascular endothelial cells, and the derangement of this regulatory system plays an important role in the pathophysiology of pre-eclampsia.
