[Acute kidney failure in glomerulonephritis and in angiitis].
Some cases of postinfectious glomerulonephritis initially are oligoanuric. Renal biopsy is essential to distinguish the purely endocapillary and exsudative form from that with endo- and extracapillary proliferation. The former characterises spontaneously regressive poststreptococcal glomerulonephritis, which is now rare, whilst the latter is caused by various strains of gram-positive and gram-negative strains and entails a much less favourable outcome in terms of renal and patient survival. Acute renal failure is a common complication of angiitis, mainly polyarteris nodosa (PAN) and Wegener granulomatosis. A third variety of crescentic glomerulonephritis is due to anti-glomerular basement membrane (GBM) antibodies, with or without pulmonary haemorrhage. Glomerular immunofluorescence discloses a typical pattern of linear IgG deposits along the GBMs. Treatment based on plasma exchanges, corticosteroids and alkylating agents can prevent end stage renal failure when undertaken early. Other glomerulopathies may be complicated with acute renal failure, including haematuric forms of IgA nephropathy.
