Immune mechanisms and the renin-angiotensin system are implicated in preeclampsia. We investigated 25 preeclamptic patients and compared them with 12 normotensive pregnant women and 10 pregnant patients with essential hypertension. Antibodies were detected by the chronotropic responses to AT1 receptor-mediated stimulation of cultured neonatal rat(More)
BACKGROUND We recently described autoantibodies (angiotensin-1 receptor autoantibodies, AT(1)-AA) directed at the AT(1) receptor in the serum of preeclamptic patients, whose placentas are commonly infarcted and express tissue factor (TF). Mechanisms of how AT(1)-AA might contribute to preeclampsia are unknown. We tested the hypothesis that AT(1)-AA cause(More)
BACKGROUND Oedema and vascular leakage play a part in the pathogenesis of pre-eclampsia. We tested the hypothesis that serum from pre-eclamptic patients increases endothelial-cell permeability and examined possible signal-transduction pathways. METHODS We studied eight patients with pre-eclampsia, eight normotensive pregnant women, eight non-pregnant(More)
Pregnant patients with increases in blood pressure are often treated with medication, in our view inappropriately. We examined 222 pregnant women who were referred because of two blood pressure determinations > 140/90 mm Hg. The women were primarily treated by nonpharmacological means. Only 44 required medications to maintain a blood pressure < 140/90 mm(More)
