  ABSTRACT: This article discusses the epidemiology, recognition, screening, and management of six systemic diseases that commonly present with renal manifestations: diabetic nephropathy, lupus nephritis, congestive heart failure, HIV, liver disease, and dysproteinemias. Diabetic nephropathy remains the leading cause of end-stage renal disease in the United States. The outlook for patients who have lupus nephritis and HIV-associated nephropathy has improved in the last decade. Kidney disease is common in patients who have advanced liver disease, and creatinine-based methods do not provide an accurate estimation of renal function in this population. Dysproteinemias are associated with protean renal manifestations, and renal disease may be the presenting manifestation.

  ABSTRACT: The kidney not only regulates fluid and electrolyte balance but also functions as an endocrine organ. For instance, it is the major source of circulating erythropoietin and renin. Despite currently available therapies, there is a marked increase in cardiovascular morbidity and mortality among patients suffering from end-stage renal disease. We hypothesized that the current understanding of the endocrine function of the kidney was incomplete and that the organ might secrete additional proteins with important biological roles. Here we report the identification of a novel flavin adenine dinucleotide-dependent amine oxidase (renalase) that is secreted into the blood by the kidney and metabolizes catecholamines in vitro (renalase metabolizes dopamine most efficiently, followed by epinephrine, and then norepinephrine). In humans, renalase gene expression is highest in the kidney but is also detectable in the heart, skeletal muscle, and the small intestine. The plasma concentration of renalase is markedly reduced in patients with end-stage renal disease, as compared with healthy subjects. Renalase infusion in rats caused a decrease in cardiac contractility, heart rate, and blood pressure and prevented a compensatory increase in peripheral vascular tone. These results identify renalase as what we believe to be a novel amine oxidase that is secreted by the kidney, circulates in blood, and modulates cardiac function and systemic blood pressure.
