Haemorrhagic shock and encephalopathy: a new syndrome with a high mortality in young children
Insights
A severe infant disorder caused encephalopathy, shock, and organ dysfunction in ten infants, with seven fatalities. The exact cause remains unknown, but proteolytic enzymes may play a role.
Area of Science:
- Pediatrics
- Infectious Diseases
- Critical Care Medicine
Background:
- A novel, severe disorder has emerged in infants over the past year.
- This condition presents with acute onset of serious systemic symptoms.
Observation:
- Ten infants were hospitalized with a previously unrecognized syndrome.
- Clinical features include encephalopathy, fever, shock, watery diarrhea, disseminated intravascular coagulation, and renal/hepatic dysfunction.
- A high mortality rate was observed, with seven out of ten infants dying.
Findings:
- No specific causative agent has been identified for this infant disorder.
- Preliminary research suggests the pathophysiology may involve the release of proteolytic enzymes, such as trypsin, into the bloodstream.
- This release is hypothesized to lead to the destruction of the microcirculation.
Implications:
- Understanding the pathophysiology is crucial for developing diagnostic and therapeutic strategies.
- Further research is needed to identify the causative agent and elucidate the exact mechanisms.
- This highlights the need for vigilance and rapid response to new pediatric critical illnesses.
Abstract:
In the past year, ten infants have been admitted to hospital with a new or previously unrecognised disorder, characterised by an acute onset of encephalopathy, fever, shock, watery diarrhoea, severe disseminated intravascular coagulation, and renal and hepatic dysfunction. Seven of the infants died. No specific causative agent has been identified, but preliminary studies suggest that the pathophysiology of the disease may involve release of proteolytic enzymes (such as trypsin) into the circulation, with destruction of the microcirculation.
