Trientine and renin-angiotensin system blockade ameliorate progression of glomerular morphology in hypertensive experimental diabetic nephropathy.

A comparison of the efficacy of the copper chelator, trientine, with combined renin angiotensin system (RAS) blockade on the progression of glomerular pathology in the diabetic (mREN-2)27 rat is reported. Animals were treated for 2 months with trientine, combined RAS blockers, combined trientine plus RAS blockers or none. Treatments began after inducing diabetes with streptozotocin.

Early intervention with erythropoietin does not affect the outcome of acute kidney injury (the EARLYARF trial).

We performed a double-blind placebo-controlled trial to study whether early treatment with erythropoietin could prevent the development of acute kidney injury in patients in two general intensive care units. As a guide for choosing the patients for treatment we measured urinary levels of two biomarkers, the proximal tubular brush border enzymes gamma-glutamyl transpeptidase and alkaline phosphatase. Randomization to either placebo or two doses of erythropoietin was triggered by an increase in the biomarker concentration product to levels above 46.
