Acute liver failure in Cuban children

Area of Science:

• Pediatric Hepatology
• Infectious Diseases
• Critical Care Medicine

Background:

• Acute liver failure (ALF) is a rare and critical pediatric emergency with significant prognostic and therapeutic challenges.
• Limited data exists on ALF in pediatric populations in Cuba, necessitating local research.

Purpose of the Study:

• To describe the clinical features of pediatric patients diagnosed with acute liver failure in Cuba.
• To identify the main etiologies and outcomes of ALF in Cuban children.

Main Methods:

• A case series study was conducted from 2005 to 2011 at a national referral center in Havana.
• Data collected included age, etiology, hepatic encephalopathy grade, blood chemistry, and clinical outcomes.
• Statistical analyses included contingency tables, Mann-Whitney U test, and calculation of case fatality and relative risk.

Main Results:

• The study included 31 children (14 boys, 17 girls) with a median age of 24 months.
• Infections, primarily nonhepatotropic viruses like cytomegalovirus in infants, were the most common etiology (61.3%).
• Case fatality was 41.9%; outcomes were significantly associated with hepatic encephalopathy grade (p <0.01) and lower cholesterol levels (p <0.01).

Conclusions:

• Clinical characteristics of ALF in Cuban children resemble those in developed countries.
• Nonhepatotropic viruses, especially cytomegalovirus, are the primary cause of ALF in Cuban infants, warranting further epidemiological investigation.
• Identifying local determinants of ALF in this population is crucial for future interventions.
