THE IMPORTANCE OF EARLY DIAGNOSIS AND TREATMENT OF ACUTE RENAL FAILURE DUE TO MICROSCOPIC POLYANGIlTIS

Microscopic polyangiitis is a non-granulomatous necrotizing vasculitis involving small vessels. Clinical manifestations are highly polymorphic, but rapidly progressive glomerulonephritis is one of the most frequent and most severe manifestations of the disease. Most patients with MPA present with or develop severe renal disease, particularly if the diagnosis is delayed. We report the case of P-ANCA-positive Microscopic polyangiitis with acute renal failure which had improved with intensive immunosupresive therapy.
