Insights
Acute liver failure (ALF) in children is often caused by viral infections, with a 44% mortality rate. Prognostic factors for mortality include high-grade encephalopathy and specific blood markers.
Area of Science:
- Pediatric critical care medicine
- Hepatology
- Infectious diseases
Background:
- Acute liver failure (ALF) is a severe condition with high mortality.
- It presents with jaundice, encephalopathy, and coagulopathy, potentially leading to multiorgan failure.
- ALF diagnosis requires no prior history of liver disease.
Purpose of the Study:
- To investigate the causes of ALF in pediatric intensive care unit (PICU) patients.
- To identify prognostic factors associated with increased mortality in pediatric ALF.
Main Methods:
- A study of 43 consecutive ALF patients admitted to a PICU.
- Analysis of etiological factors and clinical data for prognostic assessment.
Main Results:
- Etiology was identified in 91% of cases, with viral infections being the most common cause.
- The overall mortality rate was 44%.
- Factors linked to increased mortality included advanced encephalopathy grade, prolonged prodromal symptom to encephalopathy interval (>7 days), low blood glucose (<45mg/dL), high serum bilirubin (>10mg/dL), and abnormal admission pH (<7.35 or >7.45).
Conclusions:
- Viral infections are a primary cause of pediatric ALF.
- Several clinical and biochemical parameters serve as critical prognostic indicators for mortality in pediatric ALF patients.
Abstract:
Acute liver failure (ALF) is a life-threatening condition characterized by jaundice, encephalopathy and coagulopathy leading to multiorgan failure in a patient with no prior history of liver disease. Forty three consecutive patients of ALF admitted in Pediatric ICU were studied for etiology and prognostic factors. Etiology was established in 91% cases. Viral infections were the most common cause. Mortality rate was 44%. Increasing grade of encephalopathy, >7 days interval between the onset of prodromal symptoms and encephalopathy, blood glucose <45mg/dL, serum bilirubin > 10mg/dL and pH <7.35 or >7.45 on admission were found to be associated with increased risk of mortality.

Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
