Among women with diabetes, the worst pregnancy outcome is seen in the subgroup of women with diabetic nephropathy. Development of severe preeclampsia that leads to early preterm delivery is frequent. Predictors and pathophysiological mechanisms for the development of preeclampsia among women with diabetes and observational studies that support antihypertension treatment for pregnant women with microalbuminuria or diabetic nephropathy preventing preeclampsia and early preterm delivery are presented here. Obtaining and maintaining strict glycemic control before and during pregnancy is paramount to prevent preterm delivery...

Preeclampsia (PE) complicates ∼5% of human pregnancies and is one of the leading causes of pregnancy-related maternal deaths. The only definitive treatment, induced delivery, invariably results in prematurity, and in severe early-onset cases may lead to fetal death. Many currently available antihypertensive drugs are teratogenic and therefore precluded from use. Nonteratogenic antihypertensives help control maternal blood pressure in PE, but results in preventing preterm delivery and correcting fetal growth restriction (FGR) that also occurs in PE have been disappointing...

OBJECTIVE: Firstly, to examine if treatment for hypertension in pregnancy guided by the serial assessment of maternal central haemodynamics leads to a reduction in the rates of severe hypertension, defined as blood pressure greater than or equal to 160/110mmHg. Secondly, to assess the distinct longitudinal haemodynamic profiles associated with either beta-blocker monotherapy, vasodilator monotherapy, or dual agent therapy, and their relationship with outcomes including fetal growth restriction...

OBJECTIVE: Preeclampsia is a complex heterogeneous disease commonly defined by new-onset hypertension and proteinuria in pregnancy. Women experiencing preeclampsia have increased risk for cardiovascular diseases (CVD) later in life. Preeclampsia and CVD share risk factors and pathophysiologic mechanisms, including dysregulated inflammation and raised blood pressure. Despite commonalities, little is known about the contribution of shared genes (pleiotropy) to these diseases. This study aimed to investigate whether genetic risk factors for hypertension or inflammation are pleiotropic by also being associated with preeclampsia...

OBJECTIVE: Preeclampsia (PE) is pregnancy-induced hypertension with proteinuria. It causes maternal death or fetal growth restriction (FGR). Although high BP can be managed with antihypertensive drugs, there is no effective treatment of FGR associated with PE. We have clarified that nicotinamide (Nam) alleviates PE-like condition and FGR induced by soluble fms-like tyrosine kinase-1 (sFlt-1) in mice. But the mechanism of how Nam works is unclear. Because Nam induces cytoprotective heme oxygenase 1 (HO-1), our aim is to clarify whether HO-1 contributes to therapeutic effect of Nam against FGR associated with PE...

OBJECTIVE: It was observed that glomerular hyperfiltration (GHF) is associated with progression of kidney disease in diabetics, patients in stage 1 hypertension (HT), and we found previously that eGFR decreased faster also in prehypertensives (PHT) with GHF. Here we analyzed whether GHF in PHT is associated with other biomarkers of early renal impairment. DESIGN AND METHOD: From 954 subjects enrolled in ENAH follow-up study, 371(137 m;mean age = 46years) were eligible for further analysis:100 with optimal,72 with normal BP,70 with PHT(high normal BP),and 129 with newly diagnosed untreated HT...

Hypertension is the leading risk factor contributing to mortality worldwide, primarily from cardiovascular disease (CVD), while effective treatment of hypertension is proven to reduce CVD events. Along with the well recognized nutrition and lifestyle determinants, genetic factors are implicated in the development and progression of hypertension. In recent years genome-wide association studies have identified a region near the gene encoding the folate-metabolizing enzyme methylenetetrahydrofolate reductase (MTHFR) among eight loci associated with blood pressure...

BACKGROUND: Mozambique has drastically improved an array of health indicators in recent years, including maternal mortality rates which decreased 63 % from 1990-2013 but the rates still high. Pre-eclampsia and eclampsia constitute the third major cause of maternal death in the country. Women in rural areas, with limited access to health facilities are at greatest risk. This study aimed to assess the current state of knowledge and the regular practices regarding pre-eclampsia and eclampsia by community health workers in southern Mozambique...

BACKGROUND: An estimated 276 Pakistani women die for every 100,000 live births; with eclampsia accounting for about 10 % of these deaths. Community health workers contribute to the existing health system in Pakistan under the banner of the Lady Health Worker (LHW) Programme and are responsible to provide a comprehensive package of antenatal services. However, there is a need to increase focus on early identification and prompt diagnosis of pre-eclampsia in community settings, since women with mild pre-eclampsia often present without symptoms...

BACKGROUND: In India, the hypertensive disorders of pregnancy and postpartum haemorrhage are responsible for nearly 40 % of all maternal deaths. Most of these deaths occur in primary health settings which frequently lack essential equipment and medication, are understaffed, and have limited or no access to specialist care. Community health care workers are regarded as essential providers of basic maternity care; and the quality of care they provide is dependent on the level of knowledge and skills they possess...

Hypertensive disorders have become increasingly prevalent and complicate an increasing number of pregnancies. Therefore it is essential that the medications used to treat these disorders be well understood. Furthermore the management is complicated by special consideration needed for the physiologic changes of pregnancy as well as the consideration for possible adverse fetal effects. Areas covered: We performed a review of the scientific literature of medications used to treat hypertensive disorders in pregnancy...

INTRODUCTION: Increased aortic systolic BP (SBPao), pulse wave velocity (PWVao) and augmentation index of the aorta (AIXao) are associated with increased cardiovascular morbidity. These measures may also be increased prior to the development of adverse maternal and perinatal outcomes. The aim of this study was to evaluate the association between haemodynamic parameters and adverse outcomes in women with chronic hypertension (CHT). METHODS: Women recruited to the PANDA study (Pregnancy And chronic hypertension: NifeDipine versus lAbetalol as antihypertensive treatment) had Arteriograph (Tensio Med) readings taken while sitting...

Sodium hydrosulfide (NaHS) has presented antihypertensive and antioxidant effects and may reduce circulating soluble fms-like tyrosine kinase-1 (sFlt-1). We examined whether NaHS prevents maternal and fetal detrimental changes in a model of hypertension in pregnancy induced by N(G)-nitro-L-arginine methyl ester (L-NAME). Forty pregnant rats were divided into four groups (n = 10 per group): Norm-Preg, Preg + NaHS, HTN-Preg, or HTN-Preg + NaHS. Systolic blood pressure (SBP), number of viable fetuses, litter size, pups, and placentae weights were recorded...

In pregnancy, both mother and fetus benefit from blood pressure in normal ranges. There is discrepancy in the normenclature and thresholds for classification of hypertension in pregnancy and for initiation of antihypertensive treatment in different international guidelines. Systolic and diastolic blood pressure values that are associated with normal outcome are notably lower than any recommended treatment threshold in pregnancy. Tight blood pressure control under 85 mmHg diastolic is save and significantly prevents severe maternal hypertension as could be demonstrated in CHIPS...

In the first 6 months of pregnancy, the primary goal of antihypertensive treatment is to prevent the complications of severe hypertension. Initiation of antihypertensive drug treatment is recommended in pregnant women with severe hypertension (blood pressure>160/110mmHg). Initiation of antihypertensive drug treatment should also be considered in pregnant women at high cardiovascular risk (diabetes, chronic kidney disease, personal history of cardiovascular disease) with moderate hypertension (blood pressure between 140-159/90-109mmHg)...

OBJECTIVE: Chronic kidney disease(CKD) is established CV risk factor, and already early renal impairment(RI) increases risk for hypertension(HT) and loss of renal function. It was reported that blood pressure (BP) and metabolic derangements are associated with glomerular hyperfiltration(GHF), and GHF increases risk of developing microalbuminuria (MA) in HT stage 1. Our aim was to analyze whether GHF predicts progression to HT and RI in apparently healthy subjects. DESIGN AND METHOD: Out of 954 subjects enrolled in ENAH follow-up study, 371 (137 m, 234 w; mean age = 46 years) were eligible for further analysis:100 with optimal, 72 with normal BP, 70 with PHT (high normal BP), and 129 with newly diagnosed untreated HT...
