Rhabdomyolysis secondary to influenza a infection: a case report and review of the literature.

CONTEXT: Rhabdomyolysis is a serious clinical syndrome that results from damage to skeletal muscles. Common causes include drugs, crush injuries, seizures, heat, exertion, and infection. Viral infections, particularly Influenza A, have been recognized as a cause of rhabdomyolysis.

CASE REPORT: Our report describes a 58-year-old male who presented with viral pneumonia secondary to Influenza A virus infection. His hospital course was complicated by acute renal failure secondary to rhabdomyolysis, which was attributed to an overwhelming viremia. We discuss the differential diagnosis of rhabdomyolysis and review the literature for cases of Influenza A-related rhabdomyolysis. We also discuss the proposed mechanisms for the condition.

CONCLUSION: The scope of clinical manifestations of Influenza A infection extends beyond pulmonary syndromes. Rhabdomyolysis is being increasingly recognized as a complication of Influenza A infection with considerable morbidity and mortality.
