Does antihypertensive therapy modify chronic allograft failure?

Abstract

Hypertension after renal transplantation continues to affect 50% or more of patients, despite use of modern immunosuppressive regimens. Relationships between poor control of blood pressure and reduced chronic allograft survival have been clearly demonstrated, and are analogous to the well-known acceleration of progressive renal disease by coexisting hypertension. It is likely, although to date it has not been formally proven by prospective study, that effective blood pressure control has a beneficial effect on chronic allograft outcome, as in progressive dysfunction of native kidneys. A further key question is whether differing classes of antihypertensive therapy may have differing effects on long-term graft outcome. It has been proposed that glomerular hypertension, hyperfiltration and hypertrophy, secondary both to inadequate nephron mass and to loss of functioning nephrons, may contribute to chronic allograft failure. If this is true, then use of converting enzyme inhibitors may particularly benefit long-term graft outcome. However, post-transplant hypertension in cyclosporine-treated patients is associated with sodium retention and renin system suppression, and a relative lack of renoprotective action of ACE inhibitors migh...Continue Reading

Antihypertensive Agents: Mechanisms of Action

Antihypertensive drugs are used to treat hypertension (high blood pressure) which aims to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Discover the latest research on antihypertensive drugs and their mechanism of action here.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
