Lipoid nephrosis appearing as acute oliguric renal failure.
Acute oliguric renal failure previously was reported to develop in patients with preexisting idiopathic nephrotic syndrome in association with clinical evidence of vascular volume depletion. We describe an 81-year-old man without recent proteinuria or evidence of preexisting nephrotic syndrome in whom acute oliguric renal failure developed. Renal biopsy disclosed minimal change disease. Nephrotic range proteinuria without severe hypoalbuminemia was detected during the 25-day course of oliguric renal failure. Renal vein thrombosis was excluded. Urine sodium concentration and fractional sodium excretion were reduced, yet left ventricular filling pressure was not subnormal and could be increased to supernormal levels without improvement in glomerular filtration rate. Oliguria and azotemia were corrected following initiation of glucocorticoid therapy. This case suggests that lipoid nephrosis can appear as acute oliguric renal failure without historical or physical evidence of preexisting nephrotic syndrome.
