Write about Cirrhosis here. • Irreversible liver damage • Loss of normal hepatic architecture (via incorrect regeneration • Fibrosis and nodular regeneration Causes: • Chronic alcohol abuse • HBV and HCV infection • AI disease: • Primary Biliary Cirrhosis (PBC) • Primary Sclerosis Cholangitis (PSC) • Auto-Immune liver disease • Genetic Disorders: • alpha1-antitrypsin deficiency • Haemachromatosis • Others: • Drugs: • E.g. Amiodarone, methlydopa, methotrexate Presentation: • Chronic liver disease: • Leuconychia (white nails with lunulae undemarcated) - hypoalbuminaemia • Terry's Nails (white proximally but distal 30% reddened by telangiectasias) • Palmar Erythema (hyperdynamic circulation) • Spider Naevi • Dupuytren's Contracture • Gynaecomastia • Testicular Atrophy • Parotids Enlarged • Clubbing • Hepatomegaly • Small liver in late disease • Hepatic failure • coagulopathy (II, VII, IX and X down - INR up), encephalopathy, hypoalbuminaemia, sepsis, hypoglycaemia • Portal hypertension • Ascites, splenomegaly, portosystemic shunts (including oesophageal varices ± life-threatening upper GI bleed) and caput medusa (enlarged superficial periumbilical veins) • Increased risk of hepatocellular Ca Tests: • blood • Liver USS • Ascitic tap • Liver Biopsy Management: • General • Good nutrition, low salt diet, EtOH abstinence. Avoid NSAIDs, sedatives and opiates • Colestyramine may help pruritis • Consider USS screening for HCC • Specific Treatments • Interferon-alpha improves liver biochem and may retard development of hepatocellular carcinoma (HCC) in HCV induced cirrhosis • Penicillamine for Wilson's Disease Prognosis: • Overall 5 yr survival = 50% • Poor prognostic indicators: • Encephalopathy • Serum Na < 110 • Serum albumin < 25 • Raised INR Liver Transplantation: • Only definitive treatment for cirrhosis • Increases 5 yr survival in end-stage disease from 20% => 70% |
