Pediatric cirrhosis: special consideration for its diagnosis and management

Pediatric cirrhosis differs significantly from adult liver disease in terms of etiology, progression, and management. The unique physiological, nutritional, and developmental needs of children require specialized diagnostic and therapeutic strategies. This review underscores the distinct challenges in diagnosing and managing pediatric cirrhosis, focusing on its complications, management, and outcomes. Unlike adults, where cirrhosis often results from viral hepatitis or alcohol use, pediatric cases are predominantly cholestatic, with biliary atresia being the most common cause. Complications mainly involve portal hypertension and impaired liver function, leading to malnutrition and neurodevelopmental delay. Nutritional management is complex and requires increased caloric and protein intake, supplementation with fat-soluble vitamins, and the use of medium-chain triglycerides. Although hepatocellular carcinoma is rare in children, it remains a severe complication with a higher incidence in certain genetic and metabolic disorders. Surveillance is challenging due to diagnostic limitations and the lack of standardized pediatric screening protocols. Treatment is further complicated by constraints related to size and developmental stage, particularly in the management of portal hypertension. Pediatric cirrhosis requires an individualized multidisciplinary approach to address the interplay between growth, nutrition, and liver function. Early diagnosis, nutritional optimization, malignancy surveillance, and timely referral for liver transplantation are crucial. Ongoing research on pediatric-specific therapies and outcomes is essential for improving prognosis and quality of life.
