[Acute fatal hepatorenal failure during treatment with mithramycin]

A case of fatal hepato-renal failure occurring during mithramycin treatment is reported. A 64 year-old female patient was admitted to hospital in a state of acute renal failure. She also presented with hypercalcaemia and bilateral pulmonary metastases. She had been operated on 10 years previously of a parathyroid cancer. Despite treatment with mithramycin (total dose 8.25 mg) and haemodialysis, the hypercalcaemia returned; it was then decided to remove the secretory lung metastases (parathormone 420 micrograms X ml-1). 48 hours before surgery, the patient was again given 1.25 mg mithramycin. Immediately after surgery, she developed hepatic failure with massive cell destruction and anuria. The patient died 48 h after the operation. The hepatic and renal complications of mithramycin are discussed.
