Myoglobin-Associated Acute Kidney Injury in the Setting of Ciprofloxacin Administration

Myoglobin-associated kidney injury typically is seen in severe rhabdomyolysis. Nontraumatic rhabdomyolysis may be triggered by direct drug toxicity, drug-drug interactions, and individual patient myopathic risk factors. We present a case of myoglobin-associated kidney failure in the setting of repeated ciprofloxacin administration in a lung transplant patient. Kidney biopsy was critical to establishing the diagnosis and avoiding future exposure.
