title: Erythrocytosis associated with the nephrotic syndrome.
abstract: A 23-year-old-man had true erythrocytosis and the nephrotic syndrome. A renal biopsy specimen showed focal sclerosing glomerulonephritis and nephrosclerosis. Both serum and urinary erythropoietin levels were increased, and plasma renin activity was in the high normal range. The association of erythrocytosis and glomerulonephritis with the nephrotic syndrome is reviewed, and the uniqueness of this association is proposed. Finally, a dissociation between these hormones was demonstrated using water immersion to the peck as a suppressive maneuver.
