Summary Background Preeclampsia, a rapidly progressing pregnancy-specific multi-systemic syndrome is globally the leading cause of maternal and neonatal morbidity and mortality. This study aims to evaluate the serum total Lactate dehydrogenase levels in women with preeclampsia when compared to normotensive pregnant women and assess the electrophoretic pattern of the LDH isoenzymes in normal pregnancy, preeclampsia and eclampsia. Methods The study, carried out in the Department of Biochemistry of MVJ Medical College, included 30 patients of preeclampsia and 30 normotensive gestational age-matched pregnant women admitted to the Department of OBG. Serum total LDH was analysed by DGKC method. Serum and cord blood samples for isoenzyme distribution analysis were collected from a normal pregnant woman undergoing delivery, a woman with mild eclampsia, two women with eclampsia, and analysed by slab gel electrophoresis followed by activity staining. Results LDH was significantly elevated in cases as well as between the case (mild and severe) groups, showed a moderate positive statistically significant correlation with systolic, diastolic blood pressure and a sensitivity of 50% and a specificity of 80%. Further, the isoenzyme pattern showed a decreasing distribution of aerobic forms of LDH in preeclampsia-eclampsia. Conclusions Preeklampsija, multisistemski sindrom koji brzo napreduje zbog trudnoće, vodeći je uzrok morbiditeta i mortaliteta majki i novoro|enčadi. Ova studija ima za cilj da proceni nivo ukupne laktat dehidrogenaze u serumu kod žena sa preeklampsijom u poređenju sa normotenzivnim trudnicama i proceni elektroforetski obrazac LDH izoenzima u normalnoj trudnoći, preeklampsiji i eklampsiji.

BACKGROUND: According to the theory of endothelial dysfunction, the pathogenesis of preeclampsia is associated with the imbalance of angiogenic and anti-angiogenic factors. Transforming growth factor-beta 1 (TGF-β1) has also proposed as a proangiogenic factor that influences preeclampsia. This study was conducted to compare a mean difference of TGF-β1 between preeclampsia and normal pregnancy.METHODS: This study was an observational crosssectional study with 25 subjects of pregnant women with preeclampsia and 25 subjects of normotensive pregnant women. The study was conducted in Dr. Reksodiwiryo Hospital, Bhayangkara Hospital, and Dr. Rasidin Hospital in Padang, Indonesia from October 2015 to January 2016. For the determination of TGF-β1 concentration, peripheral Abstract venous blood samples were taken. The blood samples wereanalyzed by enzyme-linked immunosorbent assay (ELISA) in Biomedical Laboratory, Faculty of Medicine, Andalas University. The mean difference was statically analyzed by independent samples T-test.RESULTS: The mean difference of TGF-β1 was lower in preeclampsia group than normal pregnancy group (2.02±0.99 ng/mL vs. 3.24±2.67 ng/mL; p<0.05).CONCLUSION: The TGF-β1 concentration was lower in pregnant women with preeclampsia. Thus, it may have a role as a marker in preeclampsia.KEYWORDS: preeclampsia, normal pregnancy, transforming growth factor-beta1, TGF-β1

Background. Preeclampsia is a major cause of maternal and neonatal morbidity and mortality in sub-Saharan Africa. Evidence indicates that endothelial dysfunction is central to the pathogenesis of preeclampsia. This study assessed the level of the components of the arginine-nitric oxide pathway to evaluate endothelial dysfunction in normotensive pregnancies and pregnancies complicated with preeclampsia. Methods. This case-control study was conducted among pregnant women who visited Comboni Hospital from January 2017 to May 2018. A total of 180 pregnant women comprising 88 preeclamptic women (PE) and 92 healthy normotensive pregnant women (NP) were recruited. Sociodemographic, clinical, and obstetric data were obtained using validated questionnaires. Blood pressure and anthropometrics were measured, and blood samples were collected for the estimation of nitric oxide (NO∙), L-arginine, asymmetric dimethylarginine (ADMA), and 3-nitrotyrosine using an enzyme-linked immunosorbent assay technique. Results. The mean NO∙ ( p = 0.010 ) and L-arginine/ADMA ratio ( p < 0.0001 ) was significantly lower in PE compared to NP while mean L-arginine ( p = 0.034 ), ADMA ( p < 0.0001 ), and 3-nitrotyrosine ( p < 0.0001 ) were significantly higher in PE than NP. ADMA showed a significant positive association with systolic blood pressure ( β = 0.454 , p = 0.036 ) in severe PE. Women with PE had significant intrauterine growth restriction ( p < 0.0001 ) and low birth weight infants ( p < 0.0001 ) when compared to NP. Conclusion. Preeclampsia is associated with reduced NO∙ bioavailability, L-arginine/ADMA ratio, and elevated levels of ADMA and 3-nitrotyrosine. Measurements of the levels of these parameters can help in the early prediction of endothelial dysfunction in preeclampsia. Exogenous therapeutic supplementation with L-arginine during pregnancy to increase the L-arginine/ADMA ratio should be considered to improve endothelial function in preeclampsia and pregnant women at risk of developing preeclampsia.

Marked changes in maternal thyroid activity occur in pregnancy. During pregnancy bodily hormonal changes and metabolic demands result in complex alteration in the bio-chemical parameters of thyroid activities. Besides these, thyroid enlargement, increased thyroid capability for iodine uptake and increase in basal metabolic rate are evidential though these findings are not usually associated with symptoms of hyperthyroidism in pregnancy. Serum concentration of thyroid hormone thyroxine and triiodothyronine in complicated pregnancy like eclamptic toxemia is another field of controversy. To evaluate the changes in thyroid function in normal pregnancy and eclamptic toxemia, a study was undertaken in Rajshahi Medical College Hospital. We collected serum specimens from non pregnant but married women, normal 3rd trimester pregnant women and patients with eclampsia at 3rd trimester of pregnancy and measured serum concentrations of total and free thyroxine (TT4 & FT4) and total and free triiodothyronine (TT3 & FT3 ) by using RIA. Among the study subjects, 10 women were married but non pregnant, 12 women were in their 3rd trimester of normal pregnancy and 32 patients of eclamptic toxemia with 3rd trimester of pregnancy. In normal pregnancy, FT4 and FT3 levels remained normal while TT4 and TT3 levels were elevated. In patients with toxemia of pregnancy, the mean serum TT3 concentration was significantly lower than that of normal pregnancy and the serum FT3 concentrations were below the normal pregnancy range. The mean serum TT4 and FT4 concentrations in patients with eclampsia were however, significantly higher than those in normal pregnant women. TAJ 2018; 31(1): 9-14

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.

Background: Thyroid disorder is often overlooked in pregnant women this is because of nonspecific symptoms and hyper metabolic state of normal pregnancy. To evaluate the thyroid function in pregnant women in all the three trimesters and to study their impact on pregnancy outcome.Methods: A prospective study in 200 randomly selected antenatal cases was carried out during a period of two years in a tertiary care medical college in Western Maharashtra. A detailed general and systemic examination was carried out and Thyroid stimulating hormone (TSH) was done in all cases. Any case with an abnormal TSH level was further tested for T3 T4 levels.Results: The mean TSH level was 1.6 µIU/l which was less than the standard cut off of 2.5 µIU/l. 61% had decreasing level of TSH with advanced gestation. An abnormal thyroid function was seen in 8.5% cases.Conclusions: Standardization of TSH, T3, T4 is still a concern as it varies significantly in different studies. Estimation of TSH with T3 T4 could not be correlated during pregnancy with advancing gestational age. The real impact of hypo/hyperthyroidism on fetal outcome could not be statistically established.

Background: Hypertension is one of the most frequently encountered medical disorder in obstetrics practice and remain a major cause of maternal, fetal and neonatal morbidity and mortality. Objectives was to find out the high incidences of low serum magnesium in pre-eclampsia and eclampsia than in normal pregnancy.Methods: All consenting 50 cases of normal pregnant women and 50 women with pre-eclampsia attending antenatal clinic for checkup of ≥20 weeks who fulfills the inclusion and exclusion criteria were included in the study. Serum magnesium was measured by Calmagite method.Results: Out of 100 primigravidae 50 cases of pre-eclampsia women were in the age group of 18-30 years and the mean serum magnesium was 1.156±0.328. In contrast out of 50 cases of pregnant women were in the age group of 18-30 years and the mean serum magnesium was 1.907±0.321. The difference between the mean serum magnesium level in pre-eclampsia and normal pregnant women cases were statistically significant (p=0.0016). The study presented below it is clear that there are numerous factors that contribute to the causality of pre-eclampsia and from our analysis it was clear that the serum magnesium levels show an irregular pattern of fluctuations in cases suffering from pre-eclampsia and can be attributed to numerous physiological causes.Conclusions: Our study shows a significant reduction of serum magnesium levels in pre-eclampsia cases compared to normal pregnant women and occurrence of both maternal and neonatal complications with the serum magnesium levels decreased.

Pre-eclampsia is associated with substantial risks for the fetus and mother. Disorders of lipoprotein metabolism are reported to be a major cause of hypertension and proteinuria in pre-eclampsia. This was a cross-sectional comparative study carried out in the Department of Obstetrics and Gynecology, Sylhet, M.A.G Osmani Medical College Hospital, Sylhet during December 2013 to May 2014. 50 pre-eclampsia and 50 normotensive pregnant women's serum lipid profile were selected according to inclusion and exclusion criteria. Fasting lipid profile was measured after 10-12 hours overnight fasting. The mean age (25.12 # 3.98 years vs 24.94 # 3.90 years; p=0.820), gestational age (36.80 # 0.70 weeks vs 36.9 # 1.1 weeks ; p=0.144), and BMI (21.43 # 2.09kg/M2 vs 22.02 # 1.73kg/M2, p=0.131) were statistically similar in both pre-eclamptic women and the control pregnant women. SBP (163.70 #11.24mm of Hg vs 115.10 # 9.39mm of Hg; p<0.001) and DBP (103.6 #9.4mm of Hg vs 71.50 #5.37mm of Hg p<0.001) were significantly higher in pre-eclamptic women than that of normotensive pregnant women. Serum total cholesterol (227.56 # 55.79mg/dl vs 194.56 # 43.33mg/dl, p=0.001). serum LDL-cholesterol (147.72 #51.03mg/dl vs 119.43 # 37.17mg/dl; p=0.002) and serum triglyceride (232.06 # 65.54mg/dl vs 157.44 # 64.24mg/dl p<0.001) were significantly higher in pre- eclampsia than that of normal pregnancy; while serum HDL- cholesterol (38.96 # 2.93 mg/dl vs 45.82 # 6.11 mg/dl; p <0.001) was significantly lower in pre-eclampsia than that of control pregnancy. An abnormal lipid profile has a direct effect on endothelial dysfunction. Early detection of these parameters may help patient by preventing complications in pre-eclampsia.Medicine Today 2017 Vol.29(2): 1-4

Preeclampsia (PE) affects 2 to 8% of pregnant women and represents one of the major causes of maternal and perinatal morbidity and mortality, particularly in sub-Saharan Africa. A limited number of biomarkers have been proposed for the identification of pregnant women predisposed to preeclampsia. Syncytin-2 is an endogenous retrovirus envelope protein playing a key role in placental formation through the fusion of villous cytotrophoblasts, resulting in syncytiotrophoblast formation. The reduction of Syncytin-2 levels detected in placental tissue and on the surface of exosomes has been shown to strongly correlate with the severity of symptoms in preeclamptic patients. We were thus interested in conducting an analysis of a Benin cohort of pregnant women over the predictive value of this marker. From July 2015 to January 2017, 260 pregnant women were recruited in two health facilities. Blood samples were monthly collected from the beginning of pregnancy up to 20 weeks of gestation and exosomes were then isolated. We then compared Syncytin-2 levels in exosome preparations from women who presented PE to those with normal pregnancy. Our results showed that Syncytin-2 significantly decreased between 7 to 10 weeks of gestation in pregnant women with PE compared to normal pregnant women (p=0.02). Our study thereby suggests that Syncytin-2 could be a promising biomarker for early diagnosis of PE.

Preeclampsia is a pregnancy related high blood pressure disorder. It involves defective trophoblast invasion and decreased spiral artery remodelling. Alterations in micronutrients have been identified as one of the risk factor of preeclampsia. In this study we have estimated the levels of zinc, copper, iron and magnesium in preeclampsia and normal pregnant women. Our study revealed a significant decrease of zinc, copper and magnesium levels and significant increase of iron levels in preeclampsia compared to normal pregnant women. Thus assessment of micronutrients in pregnancy helps in decreasing the incidence of preeclampsia. Keywords: Preeclampsia, Zinc, Copper, Iron, Magnesium.

1. Serum nitric oxide (NO) levels (determined by its products of oxidation) were assessed in nonpregnant women, normal pregnant women and patients suffering from mild pre-eclampsia (MPE), severe pre-eclampsia (SPE), chronic hypertension (CHT) and CHT with pre-eclampsia (CHT+PE). The levels of NO products were significantly reduced during pregnancy in MPE (P < 0.001), CHT+PE (P < 0.01) and SPE (P < 0.05). Significant reductions of NO products were also observed in puerperium (P < 0.001) in all groups except CHT+PE (P < 0.05). 2. In normal pregnancy, three events were related to NO levels: (1) negative correlations were found between the levels of nitrite (r = −0.73, P = 0.0003), nitrate (r = −0.53, P = 0.017) and the number of weeks of gestation; (2) in the caesarean section group, the levels of NO at puerperium were significantly lower (P < 0.05) than those during pregnancy; and (3) there was a significant reduction in NO levels in the pregnant women carrying male fetuses as compared with female fetuses (P < 0.05). 3. In SPE, the patients with a family history of hypertension had lower levels of NO compared with the patients without such a history (P < 0.05). 4. A negative correlation was observed between systolic blood pressure, diastolic blood pressure and NO levels in MPE (r = −0.62, P = 0.013 and r = −0.68, P = 0.0049 respectively) and SPE (r = −0.72, P = 0.004 and r = −0.53, P = 0.037 respectively). 5. In SPE, positive correlations were observed between platelet count and nitrite (r = 0.67, P = 0.006) and nitrate levels (r = 0.56, P = 0.028). 6. In MPE, patients with anti-hypertensive treatment showed significantly (P < 0.05) higher levels of NO compared with the non-treated patients. 7. NO may be important in the physiopathology of hypertension during pregnancy, although several factors may affect its levels.
