CRESCENTIC GLOMERULONEPHRITIS AS RENAL CAUSE OF ACUTE-RENAL-FAILURE

Over a period of 5 years, we observed 28 patients with biopsy-proven c rescentic glomerulonephritis. Four of these patients were ANCA associa ted (pauci immune), I had anti-glomerular basement membrane antibodies (anti-GBM), and the other 23 cases had immune complex form (22 postst reptococcal and 1 poststaphylococcal). Acute renal failure as a main c linical feature was found in 11/28 (35.7%), all with more than 80% cre scents, including all ANCA-associated cases, anti-GEM form, and the pa tient with poststaphylococcal form. Using ''pulse'' therapy with methy lprednisolone, cyclophosphamide, and plasmapheresis, renal function wa s improved in 5/11 (45.4%), diuresis started and end-stage renal disea se was delayed. The therapy was continued orally with steroids and cyc lophosphamide. The second attack of oligoanuria developed after a peri od of 6-12 months without improvement after the therapy used previousl y (during the first attack), and it was necessary to begin chronic hem odialysis treatment.
