Rhabdomyolysis following pandemic influenza A (H1N1) infection.

Rhabdomyalysis is uncommon but potentially life-threatening. We present a 17-year-old patient who developed rhabdomyalysis following pandemic influenza A (H1N1/09) infection. With aggressive hydration her renal function remained normal throughout the entire disease course, and she steadily improved clinically. Although pneumonia and acute respiratory distress syndrome are the most common severe complications of H1N1/09 infection, clinicians should be aware that H1N1/09 infection may be complicated by rhabdomyolysis.
