Acute liver failure is frequent during heat stroke

Area of Science:

• Hepatology
• Internal Medicine
• Emergency Medicine

Background:

• Acute liver failure (ALF) is a recognized but often underestimated complication of heat stroke (HS).
• Previous studies have highlighted liver failure as a primary symptom in some heat stroke cases.
• This research aimed to further investigate the incidence and predictors of ALF in heat stroke.

Discussion:

• The study confirmed a higher incidence of ALF in heat stroke patients compared to controls.
• Hypophosphatemia on admission emerged as a significant predictor for the development of ALF during heat stroke.
• The findings underscore the importance of early recognition and management of metabolic disturbances in heat stroke.

Key Insights:

• Hypophosphatemia is a key early indicator for predicting acute liver failure in heat stroke patients.
• Continuous monitoring of phosphatemia for at least three days is crucial for all heat stroke cases, irrespective of perceived severity.
• Early identification of at-risk patients allows for timely intervention to prevent or mitigate liver damage.

Outlook:

• Further research should explore the precise mechanisms linking hypophosphatemia to ALF in heat stroke.
• Investigating targeted interventions for hypophosphatemia in heat stroke could improve patient outcomes.
• Establishing clear clinical guidelines for phosphatemia monitoring in heat stroke management is warranted.
