Post-preeclampsia Renal Project

2014-08-27 03:14:52 | BioPortfolio


The purpose of the Post-preeclampsia Renal Project is to investigate the renal function of preeclamptic women after delivery, and to determine whether the anti-hypertensive drug named benazepril efficiently improves the dysfunctions observed.


Several epidemiological studies suggest that the risk of death from cardiovascular causes among women with preeclampsia may be increased, and that preeclampsia contrary to what has been long thought, is not cured with delivery. Preeclampsia has long been considered a 2-stage disease, stage one corresponding to an impaired placental perfusion resulting from abnormal spiral artery remodeling, and stage two corresponding to the maternal manifestations of disease, characterized by hypertension and proteinuria. However, preeclampsia might include an additional, 3rd stage, that of the post-partum period (Gammill & Roberts, 2007) This phase deserves to be investigated. In particular, it is crucial to determine whether the changes that occur in renal hemodynamics during preeclampsia are reversible after more than 6 weeks, and whether PEC women are salt-sensitive after delivery.

The link between chronic kidney disease and cardiovascular mortality is well established. An independent, graded association exists between a reduced GFR and the risk of death, cardiovascular events, and hospitalization (Go et al, 2004). Besides, salt-sensitivity is associated with an increased cardiovascular and renal risk (Franco & Oparil, 2006). The Renal Post PEC study aims at establishing if the renal dysfunctions that occur in PEC women can be reversed by the administration of inhibitors of the renin-angiotensin system that are known to improve cardiovascular and renal risk profiles in hypertensive patients. By virtue of their potent renal vasodilatory properties and favourable remodelling of the GBM, ACE inhibitors may improve salt-sensitivity, endothelial function, renal plasma flow and GFR, and general renal prognosis in women who experienced from preeclampsia.

Medical and Biotech [MESH] Definitions

A condition of HYPONATREMIA and renal salt loss attributed to overexpansion of BODY FLUIDS resulting from sustained release of ANTIDIURETIC HORMONES which stimulates renal resorption of water. It is characterized by normal KIDNEY function, high urine OSMOLALITY, low serum osmolality, and neurological dysfunction. Etiologies include ADH-producing neoplasms, injuries or diseases involving the HYPOTHALAMUS, the PITUITARY GLAND, and the LUNG. This syndrome can also be drug-induced.

General dysfunction of an organ occurring immediately following its transplantation. The term most frequently refers to renal dysfunction following KIDNEY TRANSPLANTATION.

A group of disorders caused by defective salt reabsorption in the ascending LOOP OF HENLE. It is characterized by severe salt-wasting, HYPOKALEMIA; HYPERCALCIURIA; metabolic ALKALOSIS, and hyper-reninemic HYPERALDOSTERONISM without HYPERTENSION. There are several subtypes including ones due to mutations in the renal specific SODIUM-POTASSIUM-CHLORIDE SYMPORTERS.

Condition where a primary dysfunction of either heart or kidney results in failure of the other organ (e.g., HEART FAILURE with worsening RENAL INSUFFICIENCY).

A naphthalene derivative and CALCIMIMETIC AGENT that increases the sensitivity of PARATHYROID GLAND calcium-sensing receptors to serum calcium. This action reduces parathyroid hormone secretion and decreases serum calcium in the treatment of PARATHYROID DISEASES.
