[Variable presentation of antiglomerular basement membrane (anti-GBM) disease: rapid recognition vitally important].

The classic clinical presentation of anti-GBM disease, or Goodpasture's disease, is pulmonary haemorrhage in combination with rapidly progressive glomerulonephritis. However, presenting symptoms vary considerably. To illustrate this, this article describes 3 male patients with anti-GBM disease, aged 25, 27 and 25 years respectively. The first patient presented with massive haemoptysis without glomerulonephritis, the second patient presented with a microcytic anaemia, caused by subclinical alveolar bleeding, and the third patient presented with rapidly progressive glomerulonephritis in combination with respiratory failure. All 3 patients required mechanical ventilation but did survive. Two patients progressed to end-stage renal disease (ESRD). Earlier recognition might prevent respiratory failure and ESRD. Therefore, despite heterogeneous clinical presentation, immediate recognition of anti-GBM disease is vitally important in view of the potentially lethal consequences if left untreated.
