Cocaine-Induced Kidney, Liver, Lung, and Muscle Injury (C-KLM), Presenting With Foot Drop: A Case Report.

Cocaine-associated organ injury is a well-known phenomenon that may lead to multi-organ failure. Cocaine-induced kidney, liver, lung, and muscle (C-KLM) involvement is an entity with alarmingly high creatinine phosphokinase (CPK) levels exceeding 100,000 U/L. This may have fatal outcomes. Rhabdomyolysis is one of the many mechanisms of kidney injury induced by cocaine intoxication. Sympathomimetic effects of cocaine contribute to muscle Injury in addition to vasoconstriction resulting in muscle ischemia, as well as liver ischemia (shock liver). Furthermore, increased muscular activity from hyperpyrexia, seizures, and agitation due to cocaine use disorder may contribute to muscle breakdown and worsening nephrotoxicity.  The authors detail a case of a 34-year-old male intravenous drug user who presented with an inability to bear weight or move his left lower extremity due to pain, associated with severe edema of his lower extremities of acute onset. He was subsequently noted with foot drop, oliguria, and high blood pressure following cocaine intoxication. The patient began crashing rather quickly and the intensive care unit was recommended. Labs were noted with overwhelming CPK levels over 100,000 U/L and rising for which urgent hemodialysis was initiated. We detail a catastrophic cocaine-induced multi-organ failure with a positive outcome following a multidisciplinary approach.
