Diagnosis and management of glomerulonephritis and vasculitis presenting as acute renal failure.

Abstract

Acute and rapidly progressive renal failure is caused by a number of pathogenetically distinct types of glomerulonephritis, some of which are associated with systemic vasculitis. In a given patient, accurate diagnosis of the specific type of glomerulonephritis is essential for optimum treatment. Making a specific diagnosis usually requires renal biopsy or serologic analysis. The two categories of treatment for glomerulonephritis are (1) treatment for the pathophysiologic complications of glomerulonephritis, such as hypertension, fluid overload, and uremia, and (2) treatment for the inflammatory injury, which usually employs immunosuppression with steroids and cytotoxic drugs.
