PE23.15 | Chronic Liver Disease — Summary & Reflection

KEY TAKEAWAYS

Chronic liver disease in children is a diverse group of conditions unified by progressive hepatic fibrosis and its complications. The clinical presentation spans signs of hepatic insufficiency (jaundice, spider angiomata, palmar erythema, coagulopathy, encephalopathy) and portal hypertension (splenomegaly, ascites, caput medusae, varices), alongside growth failure. Age at presentation is the first discriminator for aetiology: biliary atresia in neonates (Kasai portoenterostomy before 60 days), Alagille syndrome and A1AT in infancy, Wilson disease and autoimmune hepatitis in school age and adolescence. The pathophysiology converges on hepatic stellate cell activation and TGF-beta driven fibrosis regardless of cause. Investigation combines LFT pattern analysis, aetiology-specific tests (ceruloplasmin/urine copper for Wilson, autoantibodies for AIH, A1AT phenotyping, viral markers), imaging (USG, MRCP, elastography), and liver biopsy. Management is aetiology-specific: Wilson disease — penicillamine or trientine + zinc; AIH — prednisolone + azathioprine; biliary atresia — Kasai; chronic HCV — direct-acting antivirals. All patients require nutritional optimisation and fat-soluble vitamin replacement. Liver transplant is definitive for end-stage disease.

REFLECT

Reflect on the concept of the 'therapeutic window' in paediatric CLD — the idea that treatment is most effective before cirrhosis becomes irreversible. For biliary atresia it is literally measured in days (Kasai before 60 days of age); for Wilson disease it is measured in years (chelation before decompensated cirrhosis). Think about how you would approach a child referred with 'chronic jaundice' of 3 months' duration in a district hospital — what questions would you ask, what signs would you specifically look for, and what is the first investigation you would order? Apply Kolb's cycle: describe a case you could construct, analyse what diagnosis might be missed without the right investigations, conclude by naming the disease you are most likely to miss (given Indian epidemiology), and plan what specific skills you want to practise in your liver disease clinic posting.
