Acute renal failure after intravenous use of immunoglobulin to treat myocarditis
The patient is a 60-year-old female with functional class III/IV (NYHA) heart failure of an immunomediated etiology (autoimmune myocarditis). After unsuccessful therapeutic attempts, intravenous immunoglobulin was used, leading to deterioration in renal function, a rare complication of that therapy. After hemodialysis, the patient’s renal function was restored, and the chronic heart failure improved to functional class I.
