[Hemorrhagic shock syndrome with encephalopathy]

Area of Science:

• Pediatric critical care medicine
• Neurology
• Toxicology

Background:

• Sudden febrile encephalopathy with shock, metabolic acidosis, and multi-organ failure is a rare but severe condition in infants.
• Previous reports have described this clinical presentation in otherwise healthy infants.
• Understanding the etiology and differential diagnoses is crucial for timely intervention.

Observation:

• This report details a case of sudden febrile encephalopathy with shock, metabolic acidosis, liver and renal failure, and bloody watery diarrhea in a 3 1/2-month-old infant.
• The infant was previously healthy, emphasizing the acute onset of severe illness.
• The clinical presentation shares features with known critical conditions.

Findings:

• The infant presented with a constellation of severe symptoms including encephalopathy, shock, metabolic acidosis, and organ dysfunction.
• Bloody watery diarrhea was a prominent gastrointestinal symptom.
• The authors explore potential links between this presentation and malignant hyperthermia and Reye syndrome.

Implications:

• This case underscores the importance of considering a broad differential diagnosis in critically ill infants with unexplained febrile encephalopathy.
• Recognizing similarities to malignant hyperthermia and Reye syndrome may guide diagnostic and therapeutic strategies.
• Further research is needed to elucidate the underlying mechanisms and optimal management for this specific infant syndrome.
