Progress in Progression? [PDF]

Journal of the American Society of Nephrology, 2010
Diabetic nephropathy is the major cause of ESRD in the United States.1 Unfortunately, only angiotensin-converting enzyme inhibitors or angiotensin type 1 receptor blockers are registered for slowing the progression of diabetic nephropathy—but they do not halt progression.2–5 Given that diabetic nephropathy costs the health care system close to $30 ...
