A case of colchicine-induced rhabdomyolysis is reported. A 48 year old African-American male with history of hypertension and chronic gout on colchicine 0.6 mg daily presented with symptoms of a community acquired pneumonia. The patient was started on 500 mg of clarithromycin orally twice daily and represented to the emergency room after 3 days complaining of severe muscle pain. His liver panel showed elevations in the serum aminotransferases; AST 513 mU/ml (nl 15-41) and ALT 182 mU/ml (nl 17-63). His complete blood count showed an elevated white blood cell count of 18,800/ml (nl 4,000-10,000/ml). Urine analysis was positive for myoglobin with no red cells present. Serum creatine kinase (CK) was 22,996 mU/ml (nl 31-221) with a normal troponin I 0.18 (nl <0.4).Investigations confirmed the presence of rhabdomyolysis and discontinuation of colchicine and clarithromycin resulted in resolution of clinical and biochemical features of rhabdomyolysis. By hospital day four, his muscle soreness had improved markedly. His serum CK improved to 3,389 mU/ml (nl 31-221 mU/ml) and serum creatinine improved to 1.5 mg/dl (nl 0.8-1.2). On hospital day five, the patient was discharged on oral anti-hypertensive medication and a ten-day course of doxycycline. Metabolism of colchicine by the cytochrome P450 3A4 system has been previously described, but this is the first published report of colchicine associated rhabdomyolysis secondary to drug metabolism interactions with an antibiotic. A review of medications that are metabolized via the cytochrome 3A4 and A-SLAVED-LIVER (Amiodarone, Simvastatin, Lovastatin, Atorvastatin, Verapamil, Erythromycin, Diltiazem, cLarithromycin, Itraconazole, Voriconazole, colchicinE, Ritonavir) pneumonic was established.

A 67-year old man was hospitalized due to an aorto-coronary bypass and cecal perforation. After administration of atorvastatin, amiodarone, and fluconazole, rhabdomyolysis developed with electrolyte disturbances (hyperphosphatemia, hyopcalcemia) and a massive increase in creatine kinase and myoglobin. In the clinical course, other complications manifested such as acute renal failure, critical illness myopathy, acute gout on the knee, and sternal infection with coagulase-negative staphylococci. After stopping the assumed causal agents and treating the complications, the patient could be transferred for rehabilitation after a more than two months hospital stay. We discuss the causes and symptoms of muscle diseases as well as the epidemiology, mechanisms, treatment, and prevention of drug-induced myopathies with a focus on statins.

Renal transplant recipients are prone to develop drug toxicities because of polypharmacy and drug-drug interactions. Colchicine is often used for the treatment of gout in these patients as nonsteroidal medications are contraindicated. In addition, patients are often on corticosteroids and frequent, periodic, dose escalation for gouty flare may lead to side effects. Colchicine-induced myopathy has been very well described in the literature. Several cases of colchicine toxicity have been reported in cyclosporine-treated patients due to a drug-drug interaction. We report a 62-year-old African American renal transplant recipient who had been doing well on tacrolimus-based immunosuppression and was started on colchicine (0.6 mg twice daily) for gouty flare. A few days later, he was found to have a 4-fold increase in aspartate aminotransferase and an elevated creatine phosphokinase. Although this interaction is very well known with cyclosporine, it has not yet been reported in patients on tacrolimus.
