RENAL INSUFFICIENCY IN THE TROPICS.

Renal dopamine system in chronic renal insufficiency

In the periphery, physiological dopamine increases renal blood flow, decreases renal resistance and acts on the kidney tubule to enhance natriuresis and diuresis. Dopamine receptors can be divided into D1-like (D1 and D5) receptors that stimulate adenylyl cyclase and D2-like (D2, D3 and D4) receptors that inhibit adenylyl cyclase. Both the D1-like and D2-like receptors are expressed in the kidn...

The ferumoxytol in renal insufficiency study (FiRST)

Background Imaging in patients with renal insufficiency (RI) is limited by contrast induced nephropathy and nephrogenic systemic fibrosis. Ferumoxytol is an FDA approved superparamagnetic iron compound used for the treatment of anemia in patients with renal insufficiency. Previous studies of its use as an MRA contrast agent did not assess safety, were not conducted in patients with RI, and were...

Familial renal insufficiency.

The picture of chronic renal insufficiency in childhood is not common, and instances of more than one member of a family with this picture are comparatively rare. Mitchell (1930), in an exhaustive review of the literature of chronic interstitial nephritis in childhood, quotes 14 instances in which more than one child in the family was affected. Graham and Hutchinson (1941) have described a fami...

Renal insufficiency and failure.

Renal impairment is a common complication of multiple myeloma. Chronic renal failure is classified according to glomerular filtration rate as estimated by the MDRD (modification of diet in renal disease) formula, while RIFLE (risk, injury, failure, loss and end-stage renal disease) and AKIN (acute renal injury network) criteria may be used for the definition of the severity of acute renal injur...
