Case ReportsFatal toxic myopathy attributed to propofol, methylprednisolone, and cyclosporine after prior exposure to colchicine and simvastatin.
We report a fatal case of toxic myopathy in a patient with a transplanted heart for severe ischemic coronary artery disease. He was on long-term cyclosporine, prednisone, and mycofenolate. Four months before the development of proximal muscle weakness, his simvastatin dose was doubled, and he was also started on colchicine for acute exacerbation of gout. ⋯ These changes led to a marked elevation of creatine kinase, peaking at 33,580 U/ml. The muscle biopsy revealed toxic vacuolization, mitochondrial damage, and no evidence of inflammation. Based on the timing of events, the combination of propofol, high-dose methylprednisolone, and cyclosporine have triggered rhabdomyolysis, which may have been facilitated by prior administration of colchicine and simvastatin.
