Abstract

Exertional heat stroke (EHS) is a life-threatening entity characterized by elevated core temperature with potential for multiorgan dysfunction. EHS-related rhabdomyolysis usually occurs in the early phase. We report a boy athlete with EHS-related rhabdomyolysis, which recurred 15 and 79 days after the initial event. This case indicates that EHS can cause recurrences of rhabdomyolysis along with persistent symptoms, which could hamper the return to daily activity. Children with EHS, particularly athletes, may be at risk for recurrent rhabdomyolysis.

  Fig. 1. The changes in the 12-year-old boy athlete’s serum concentrations of CK, myoglobin, AST, and ALT since the first arrival to the emergency department. The CK increased to 3,030 IU/L (+ 1 day), and normalized before the first discharge (104 IU/L) (+ 8 days). The second surge of CK above 20,000 IU/L was observed (+ 15 days), and that of 1,196 IU/L at the second discharge (+ 36 days). The third surge of CK occurred 50 days after the first arrival, peaking at 3,665 IU/L (+ 79 days). CK: creatine kinase, AST: aspartate aminotransferase, ALT: alanine aminotransferase.
