IgA nephropathy can cause rare lung issues like diffuse alveolar hemorrhage. Aggressive immunosuppression, including plasma exchange and steroids, successfully treated a patient with this condition.

Area of Science:

  • Nephrology
  • Pulmonology
  • Immunology

Background:

  • Immunoglobulin A (IgA) nephropathy is a primary glomerulonephritis.
  • Pulmonary manifestations, such as diffuse alveolar hemorrhage (DAH), are rare in IgA nephropathy.
  • End-stage renal disease (ESRD) necessitates renal replacement therapy like hemodialysis.

Observation:

  • A 20-year-old male with ESRD on hemodialysis presented with hemoptysis and respiratory failure.
  • Transbronchial lung biopsy confirmed pulmonary capillaritis.
  • The patient experienced recurrent respiratory distress.

Findings:

  • Pulmonary capillaritis was diagnosed as the cause of DAH in this IgA nephropathy patient.
  • Treatment involved intravenous methylprednisolone and plasma exchange.

  • Subsequent oral prednisone and cyclophosphamide were administered.

    • Implications:

    • This case underscores the potential for independent renal and pulmonary involvement in IgA nephropathy.
    • Aggressive immunosuppressive therapy is effective in managing DAH secondary to IgA nephropathy.
    • Highlights the importance of considering pulmonary capillaritis in IgA nephropathy patients with hemoptysis.
