Abstract Background Renalase (RNL) is a controversial enzyme as to whether it oxidizes catecholamines (CAs) (as is generally accepted) in the blood or not. CAs (dopamine [DPMN], epinephrine [EPI] and norepinephrine [NEPI]) are associated with hypertension, including pregnancy-induced hypertension, which occurs in 8–10% of all pregnancies. Therefore, the aim of the study was to compare CAs and renalase concentration in (i) normotensive controls (C), (ii) patients with preeclampsia (PE) and (iii) patients with severe preeclampsia (SPE), which is one of the well-known symptoms of hypertension. Methods This case-control study involved 90 women divided into three groups – 30 C, 30 PE and 30 SPE – whose age and body mass indexes (BMIs) were similar. A total of 270 blood samples (90 maternal samples, 90 umbilical cord artery samples and 90 umbilical cord vein samples) were obtained. CAs and RNL concentrations of the biological samples were measured by enzyme-linked immunosorbent assay (ELISA). Results Comparing the amounts of CAs, RNL and systolic blood pressure (SBP)/diastolic blood pressure (DBP) between healthy control pregnant women and pregnant women with PE and SPE (SBP/DBP was 120/80 mm Hg for C, above 140/90 mm Hg for PE and above 160/110 mm Hg for SPE), the levels of CAs were significantly increased whereas RNL was reduced. The correlation between SBP/DBP and the amount of RNL in pregnant women with PE and SPE was negative. Conclusions These novel results are evidence that hypertension seen in PE and SPE is directly related to increased levels of CAs and reduced RNL concentrations. The use of RNL preparations may be preferred in future to prevent maternal and perinatal morbidity and mortality due to pregnancy-induced hypertension.

Background: Pre-eclampsia poses a significant potential risk of hypertensive disorders during pregnancy, a leading cause of maternal deaths. Hyperuricemia is associated with adverse effects on endothelial function, normal cellular metabolism, and platelet aggregation and adhesion. This study was designed to compare serum urate levels in normotensive pregnant women to those with pregnancy-induced hypertension, and to evaluate its value as a potential predictive marker of hypertension severity during pregnancy. Methods: A prospective, observational, case-control study conducted on 100 pregnant women in their third trimester. Pregnant women were classified into two groups (n=50) according to arterial blood pressure measurements: group I had normal blood pressure, and group II had a blood pressure of ≥ 140/90, which was further subdivided according to hypertension severity into IIa (pregnancy- induced hypertension, IIb (mild pre-eclampsia), and IIc (severe pre-eclampsia). Blood samples were obtained on admission. Serum urate, high sensitive C-reactive protein, and interleukin-1β levels, and lipid profile were compared among the groups. Results: A significant increase in the mean values of serum urate, C-reactive protein, and interleukin- 1β levels was detected in gestational hypertensives. In addition, there was a positive correlation between serum urate levels and C-reactive protein and interleukin-1β, as well as between serum urate levels and hypertension severity. Conclusion: Hyperuricemia and increased C-reactive protein and interleukin-1β serum levels correlate with the severity of pregnancy-induced hypertension, and these biomarkers may play a role in the pathogenesis of pre-eclampsia. Serum urate measurement is sensitive, reliable markers that correlate well with the severity of hypertension in pregnant females with pre-eclampsia.

1. Forearm venous tone was measured in two groups of pregnant women: one group with pregnancy-induced hypertension and the other group with normal blood pressure. 2. The women with pregnancy-induced hypertension were venoconstricted in the forearm (P < 0.01) compared with the pregnant women with normal blood pressure. However, there was no difference in venous tone between the women with pregnancy-induced hypertension and nonpregnant women. 3. There was an inverse correlation between mean arterial blood pressure and forearm venous tone (r = −0.581, P < 0.001) for all the pregnant women studied. Further evaluation of peripheral venous tone may provide valuable information about the pathophysiology and treatment of women with pregnancy-induced hypertension.

The pathophysiology of pregnancy-induced hypertension and preeclampsia may involve abnormalities in placentation and the Fas/Fas ligand system. Hypothesizing abnormal plasma Fas and Fas ligand in pregnancy-induced hypertension, we recruited 20 hypertensive pregnant women at mean week 15 and 29 at week 30: 18 were studied at both time points. Control groups were 20 normotensive pregnant women at week 20, 29 women at week 27, and 50 nonpregnant women. sFas and sFas ligand (sFasL) were measured by enzyme-linked immunosorbent assay (ELISA). The hypertensive women had lower sFasL at both stages of their pregnancy ( P < .05). There were no differences in sFas. In 18 hypertensive pregnant women, sFasL fell from week 15 to week 29 ( P < .03). We conclude that sFas and sFasL is unchanged in normal pregnancy. Hypertension in pregnancy is characterized by low sFasL, and levels fall from weeks 15 to 29. This may reflect differences in placentation in the differing physiological and pathological states.

1. Forearm venous tone was measured in the left lateral supine position and in response to passive leg elevation in a group of women with pregnancy-induced hypertension and compared with a group of normotensive pregnant women and a group of non-pregnant women. 2. The women with pregnancy-induced hypertension were venoconstricted in the supine position compared with the normal pregnant women (P < 0.002). There was no difference in forearm venous tone between the women with pregnancy-induced hypertension and the non-pregnant women. 3. In response to passive leg elevation the women with pregnancy-induced hypertension venodilated (P < 0.002) whereas there was no change in forearm venous tone in the normotensive pregnant women and the non-pregnant women. There was no change in blood pressure in any of the women after 35 min of leg elevation. 4. These results demonstrate that the abnormal venous vasoconstriction that occurs in women with pregnancy-induced hypertension in the supine position is corrected by passive leg elevation, a manoeuvre which leads to an increase in central blood volume.

Sri Lanka has shown relatively good maternal outcome indicators for a developing country. However, high maternal deaths from pregnancy induced hypertension and pre-eclamptic toxemia raise questions about the quality of detection and treatment at field antenatal clinics, which is the primary care setting for pregnant women. The objective of the study was to assess the quality of facilities and services provided at the field antenatal clinics to di-agnose pregnancy induced hypertension or pre-eclamptic toxemia. It was a cross-sectional study. This study was set in field antenatal clinics and was conducted in two stages based on the Lot Quality Assurance Sampling method. In the first stage 55 antenatal clinics were selected from 11 Medical officers of Health areas, and in the second stage 275 pregnant women were recruited from these 55 clinics. Quality of services and quality of facilities were assessed using observation checklists. The quality of facilities was better than the quality of services in the Colombo district. The quality of facilities was acceptable in all areas other than for the presence of the Medical Officer. The quality of services was unacceptable in all areas for history taking and examination. Investigation for urine albumin was also unacceptable in all the areas. The sensitivity for measuring the systolic blood pressure and the diastolic blood pressure were 57% (95% CI: 47.4%–66.8%) and 16.7% (95% CI: 9.4%–24%) respectively. Urgent steps should be taken to improve the quality of care in the substandard areas to reduce the leading cause of maternal mortality in Sri Lanka.

Purpose: To investigate the efficacy of the combined use of normodyne and magnesium sulfate in the treatment of pregnancy-induced hypertension, and its effect on vascular endothelial growth factor (VEGF) and factor receptor-1 (Flt-1) levels in serum.Methods: A total of 100 patients with pregnancy-induced hypertension attending Maternal and Child Health Hospital of Xinjiang Uygur Autonomous Region, Xinjiang, China, were categorized as Group A, and then further subdivided into control sub-group (who were treated with magnesium sulfate only) and study sub-group (treated with magnesium sulfate plus normodyne). Furthermore, 100 healthy pregnantwomen attending the hospital for prenatal examination during the same period were categorized as Group B. Serum expressions of VEGF and Flt-1 in all patients were determined and compared. The therapeutic effect, adverse reactions, adverse pregnancy outcomes, blood pressure before and after treatment, 24 h proteinuria, and serum expression levels of VEGF and Flt-1 in the study and control groups were determined and compared.Results: Serum VEGF levels in patients with pregnancy-mediated hypertension were significantly lower than those of healthy pregnant women, and Flt-1 was raised in healthy pregnant women (p < 0.05). In the study group, treatment was markedly more effective, and the degree of amelioration of blood pressure, 24 h proteinuria, serum VEGF, and Flt-1 were significantly higher than for control sub-group. There were lower adverse pregnancy outcomes in study sub-group than in control (p < 0.05).Conclusion: The combination of magnesium sulfate and normodyne produces greater clinical efficacy in the treatment of patients with pregnancy-induced hypertension than magnesium sulfate alone, and also shows a high safety profile.
