Summary
Heat stroke is a growing concern for distance runners. This case highlights severe complications including acute kidney injury and multi-organ damage in a runner during a hot and humid event.
Area of Science:
- Sports Medicine
- Environmental Physiology
- Emergency Medicine
Background:
- Increasing incidence of heat stroke in endurance athletes.
- Importance of environmental factors (temperature, humidity) in exercise-induced heat illness.
Observation:
- A 41-year-old male runner collapsed during a 10-km race in 31.6°C and 80% humidity.
- Presented with acute renal failure, rhabdomyolysis, disseminated intravascular coagulation, and hepatic damage.
Findings:
- Required repeated peritoneal dialysis and hemodialysis due to acute kidney injury and hyperuricemia.
- Achieved near-complete recovery over 4 months, with serum creatinine levels significantly improving.
Implications:
- Highlights the critical risk of heat stroke even in "fun run" settings.
- Underscores the need for vigilant monitoring and prompt medical intervention for exertional heat illness.
- Emphasizes the potential for severe multi-organ involvement and the necessity of aggressive supportive care.
