Exertional heat stroke with pronounced presentation of microangiopathic hemolytic anemia: A case report

Year: 2024

Type: article

Abstract: BACKGROUND: Exertional heat stroke (EHS) is a critical condition arising from prolonged physical exertion in high temperatures that typically presents with normal hemoglobin levels. However, atypical presentations can also occur, leading to significant complications such as hemolytic anemia and organ dysfunction. CASE SUMMARY: This case report describes a male patient who experienced moderate-to-severe anemia that was difficult to correct, with a confirmed diagnosis of microangiopathic hemolytic anemia accompanying multiple organ dysfunction syndrome, indicative of critical EHS. Despite intensive resuscitation efforts, the patient's condition deteriorated, necessitating admission to the intensive care unit for advanced management. CONCLUSION: This case highlights the importance of recognizing atypical presentations of EHS, particularly that with significant hemolytic anemia and concurrent organ failure. Clinicians should maintain a high level of suspicion for these complications in patients displaying symptoms of heat-related illness, especially when caused by strenuous activity, as early diagnosis and intervention are crucial to improve patient outcomes.
