Diagnostic Considerations
Conditions that affect the lung and kidney (pulmonary-renal syndromes) are important in the differential diagnosis. These include Wegner granulomatosis, systemic lupus erythematosus, microscopic polyangiitis, and other forms of systemic vasculitides. Distinguishing Wegener granulomatosis from Goodpasture syndrome is particularly important. Interestingly, some patients with Goodpasture syndrome may present with antineutrophilic cytoplasmic antibodies (ANCAs), which are predominantly observed in patients with Wegener granulomatosis.[6]
Pulmonary-renal syndromes are less commonly a manifestation of IgA-mediated disorders (eg, IgA nephropathy or Henoch-Schönlein purpura) and of immune complex–mediated renal disease (eg, essential mixed cryoglobulinemia). Rarely, rapidly progressive glomerulonephritis alone can cause Pulmonary-renal syndromes through a mechanism involving renal failure, volume overload, and pulmonary edema with hemoptysis. Careful attention to the medical history, physical examination, and targeted laboratory evaluation often suggests the underlying cause.
