Hypertension during pregnancy increases fetal growth retardation, preterm deliveries, and perinatal deaths, and yet its causes remain unclear. In HIV-infected women, preterm birth additionally increases the risk of HIV transmission to the infant. Oxidative stress and endothelial cell dysfunction of the placenta have been implicated in the development of hypertension ...

Preeclampsia has been suggested to be a two-stage disorder of an alteration in placental perfusion (stage 1) leading to generalized vascular endothelial damage (stage 2). Because the mechanism linking the two stages remains unclear, effective primary prevention is still impossible. However, advances made in our understanding of the pathophysiology of ...

OBJECTIVES: To investigate feto-maternal bone turnover in normal pregnancy and preeclampsia and to test the hypothesis whether the reported low bone mass at birth in small-for-gestational age infants is associated with decreased bone formation or increased bone resorption. METHODS: Thirty-two patients with preeclampsia (17 mild and 15 severe) and 20 ...

In patients with pulmonary hypertension, pregnancy is associated with a high risk of maternal death. Such patients are counselled to avoid pregnancy, or if it occurs, are offered early interruption. Some patients, however, decide to continue with their pregnancy and others may present with symptoms for the first time whilst ...

A 40-year-old woman had pregnancy-induced hypertension, disseminated intravascular coagulation (DIC), choroidal infarction, and magnetic resonance imaging (MRI) high-signal abnormalities in the occipital regions. With successful treatment of the hypertension and spontaneous resolution of the DIC, the MRI signal abnormalities resolved, but visual acuity remained decreased because of damage to the ...

Preeclampsia is a hypertensive disorder unique to pregnancy with consistent involvement of the kidney. The renin-angiotensin system (RAS) has been implicated in the pathogenesis of preeclampsia. In the gravid state, in addition to the RAS in the kidney, there is a tissue-based RAS in the uteroplacental unit. Increased renin expression ...
Brown Mark A - - 2005
BACKGROUND: The significance of dipstick or microscopic hematuria in pregnancy is uncertain, with some studies suggesting this is associated with a greater risk for preeclampsia. We sought to determine the prevalence and clinical significance of microscopic hematuria during pregnancy. METHODS: This was a prospective case-control study in the antenatal Clinic ...

The purpose of the study was to investigate the influence that pregnancy has on the progression of primary nephrotic syndrome (NS). We investigated in pregnant rats the clinical characteristics of NS, including urinary protein concentration, serum albumin, cholesterol, triglycerides, urea, creatinine and electrolytes (potassium, sodium, calcium). Proteinuria and edema increasing ...

A meta-analysis of randomized controlled trials suggests that nifedipine appears to be a reasonable agent for treatment of acute severe hypertension in pregnancy. However, in a 1999 survey of Canadian practitioners, most stated that they rarely or never use nifedipine capsules for treatment of acute severe pregnancy hypertension. Also, there ...

ACE inhibitors are commonly used drugs in the management of adult hypertension. However their use in pregnant women can have serious effects on the fetus. In this manuscript we report a case of fatal neonatal renal failure associated with maternal intake of enalapril during third trimester and review the related ...

Context: The presence of significant proteinuria in Pregnancy Induced Hypertension is associated with worse maternal and fetal outcome. Unfortunately, Dipstick strips, currently used widely for detection and quantitation of proteinuria, have been shown to be unreliable. This creates the need for a more accurate method for early detection and quantitation ...

BACKGROUND: Both hemodynamic abnormalities and thrombophilia predispose to pregnancy-associated vascular complications such as fetal growth restriction, stillbirth, preeclampsia, and placental abruption. Antithrombotic treatment may reduce the risk for these events. In this study we tested the hypothesis that in normotensive thrombophilic formerly preeclamptic women certain alterations in hemodynamic function as ...

OBJECTIVE: Secondary hypertension during pregnancy usually carries high maternal and fetal morbidity and mortality rates. A rare form of monogenic hypertension is familial hyperkalemia and hypertension, which is caused by mutations in the kinases WNK1 or WNK4 and other unknown molecular defects. The purpose of the study was to examine ...

Pregnancy-induced hypertension (PIH), also known as preeclampsia, remains one of the leading causes of maternal death worldwide. The term preeclampsia describes the development of hypertension with proteinuria and/or pathologic edema after the 20th week of gestation. The parturient with PIH usually has multiple organ alterations, which may affect the selection ...

BACKGROUND: Preeclampsia is a pregnancy-specific disease which is one of the leading causes of maternal and fetal morbidity and mortality. The etiology of preeclampsia remains elusive. The underlying pathology may be related to a generalized intravascular hyperinflammatory state. Since the placental histopathologic lesions of acute atherosis, seen in preeclampsia, bear ...

Studies based on conventional office blood pressure (BP) measurements concluded that both maternal age and parity have significant effects on BP during pregnancy. Previous results have also indicated predictable trends of BP variability with gestational age. Accordingly, we have evaluated possible differences in the circadian pattern of ambulatory BP as ...

OBJECTIVE: One of the major complications of pregnancy, preeclampsia makes pregnancy termination inevitable in most cases. Similarities exist between the mechanisms that maintain normal pregnancy, allograft transplants, and, it is postulated, peripheral self-tolerance. In addition, the critical role of the cytotoxic T-lymphocyte antigen-4 (CTLA-4) molecule in maintaining self-tolerance has been ...

Benign intracranial hypertension (BIH) or idiopathic intracranial hypertension (IIH) is a rare disorder of unknown etiology that is most often seen in obese women of reproductive age (19.3/100,000) and is reported only occasionally during pregnancy. Both pregnancy and exogenous estrogens are thought to promote IIH or worsen it. It can ...

Bed rest or restriction of activity, with or without hospitalisation, have been advocated for women with hypertension during pregnancy to improve pregnancy outcome. However, benefits need to be demonstrated before such interventions can be recommended since restricted activity may be disruptive to women's lives, expensive, and increase the risk of ...

Hypertension in pregnancy and vascular placental insufficiency are considered common pathogenic factors in human intrauterine growth retardation (IUGR). IUGR neonates experience higher mortality, and the surviving infants have a higher incidence of neurological and intellectual impairment. To mimic this condition, we used pregnant spontaneously hypertensive rats (SHR) and performed biometric ...

Normal pregnancy is associated with a systemic inflammatory response. The response is exacerbated in preeclampsia and can account for its clinical features. Many of the physiologic changes of normal pregnancy are part of an acute-phase reaction, which is generated by an inflammatory response. The placenta is the proximal cause of ...

A 31-year-old woman with end-stage renal disease was referred to the Toronto General Hospital (Ontario, Canada) for conversion from conventional hemodialysis (CHD; 4 h/session, 3 sessions/wk) to nocturnal hemodialysis (NHD; 7 h/session, 5 to 6 treatments/wk) because of refractory hypertension. As expected, blood pressure control was superior with NHD therapy, ...

The benefits of antihypertensive therapy in pregnancy remain uncertain. Blood pressure control to prevent or correct severe hypertension can avert maternal target organ damage and may allow obstetricians to prolong pregnancy or avoid hospitalization. Several factors limit the conclusions derived from systematic review of the available studies, including failure to ...

BACKGROUND: The etiology of preeclampsia remains obscure. To study the role of insulin resistance in preeclampsia, we compared fasting insulin and glucose changes during the second and third trimesters in preeclamptic women with a normal control group. PATIENTS AND METHODS: In a nested case-control study, subjects were selected from a ...
