Hormonal modulation of proteinuria in the nephrotic syndrome.
Proteinuria is the primary manifestation of a variety of glomerular diseases which are characterized clinically by the nephrotic syndrome. In many cases there is little effective treatment for the primary disease process. However, reduction of proteinuria can frequently improve the hypoalbuminemia, hyperlipidemia and edema which are responsible for the morbidity of the nephrotic syndrome. Proteinuria can be reduced in nephrotic humans and experimental animal models by restriction of dietary protein intake, nonsteroidal anti-inflammatory drug, and by angiotensin-converting enzyme inhibitors. Each of these therapies modifies the activity of locally acting glomerular hormones, autocoids, suggesting that there is a component of proteinuria which is hormonally mediated. The effects of dietary protein, nonsteroidal anti-inflammatory drugs, and angiotensin-converting enzyme inhibitors on nephrotic proteinuria and their potential hormonal mechanisms of action is the subject of this review.
