Preface
Decoding the significance of proteinuria as an indicator of severity or prognosis in kidney disease is a stimulating challenge to students and practitioners of nephrology. Sir Richard Bright in 1827 associated proteinuria with the disease that bears his name. In the subsequent more than a century and a half, however, the meaning of the linkage between proteinuria and renal disease remains elusive.
Proteinuria is discovered on routine urinalysis in about 10 million Americans, most of whom express no symptoms of kidney disease, each year. From the studies of Robinson (updated in these pages), we know that proteinuria, per se, can be present for 20 years without change in renal function, as described in orthostatic proteinuria. By contrast, proteinuria may be the harbinger of swift kidney destruction, rarely culminating in clinical collapse, a syndrome typifying "malignant proteinuria" as detailed herein by Avram.
Although proteinuria is ubiquitous, an orderly management strategy for rational handling of proteinuria of less than nephrotic range is lacking. Separation of tubular proteinuria and transient proteinuria of fever is now possible routinely. This book provides a record of the contributions of investigators and clinicians whose work forms the substrate for production of understanding and, ultimately, marching orders for practitioners seeking optimized management for their proteinuric patients.
Generations of investigators have attempted to connect specific urinary proteins with distinct kidney disorders. This feat was the result of serendipity in the 1950 observation that Bence Jones proteins are present in most patients with multiple myeloma. Over the ensuing 20 years, it was learned that small amounts of Bence Jones protein may be present in normal urine and, more importantly, that the careful study of these urinary constituents and their precursors would serve as a Rosetta stone for clarification of modern immunology.
Might we repeat the successes of the multiple myeloma story by readdressing superficially simple questions? What is proteinuria? What

does its presence mean? And how does its presence alter the biology of the patient or the function of the kidney? Despite its high prevalence, we do not know whether proteinuria is injurious to the kidney or is the product of renal damage, nor do we know (with limited exceptions such as the proteinuria of diabetes or uncontrolled hypertension) how to prevent or whether and in what way to treat it.
Until the significance to the patient of documenting proteinuria is elucidated, it will continue as an under detected and inadequately studied mark of kidney disease. As our society reappraises health care costs, including billions spent on t~e treatment of renal insufficiency, it is appropriate to direct energy and resources in an attempt to prevent renal disease. Toward this goal, the Division of Nephrology's Avram Center for Kidney Diseases of The Long Island College Hospital in Brooklyn assembled these manuscripts on "Proteinuria." It is the editor's hope that this volume will convey the excitement and enthusiasm of the authors. It is the wish of all who contributed that the new information developed may benefit the many patients found to have proteinuria.
This book is divided to consider first a description of proteinuria and its relationship to glomerular and tubular functions. Subsequently, the clinical consequences and management of proteinuria are reviewed. A unique variety of renal protein loss termed "malignant proteinuria" is described, along with its management by pharmacological functional desctruction of the kidneys, a desperate therapeutic maneuver for desperately ill patients, which is euphemistically called medical nephrectomy.
In this tome, representing contributions by brilliant researchers from our prestigious national universities from coast to coast, we take a step in the direction of finding needed answers for the millions of Americans who have proteinuria. Converting tens of years of work by my colleagues and me into a synthesis of the state of the art of proteinuria research has been a fulfilling labor of joy.
