Jaundice, hepatitis B, alcohol and cirrhosis, portal hypertension, gallbladder and pancreas. Drawn by TrackNation.

Bilirubin and Jaundice

• Haemoglobin breakdown gives unconjugated bilirubin, carried on albumin to the liver for conjugation. Jaundice shows at about 2–3 mg/dL.

• Unconjugated: haemolysis, reduced uptake (heart failure, fasting), reduced conjugation (Gilbert syndrome; Crigler-Najjar). Conjugated: hepatocellular disease (drugs, toxins, viral hepatitis, alcohol) or bile-flow obstruction. Dark urine marks conjugated bilirubin and can appear before visible jaundice.

Hepatitis

HAV and HEV spread faecal-orally (epidemics); HBV, HCV and HDV by blood. HDV is an incomplete virus that needs HBV. Chronic HBV leads to cirrhosis and raises HCC risk even without cirrhosis. Donor screening for HBsAg has nearly eliminated transfusion hepatitis B.

Alcohol, Cirrhosis and Portal Hypertension

• Alcohol: fatty liver (> 90%), alcoholic hepatitis (10–35%), cirrhosis (10–20%). Ballooned hepatocytes and Mallory (alcoholic hyaline) bodies; AST:ALT ≥ 2 because pyridoxal phosphate deficiency lowers ALT. Micronodular cirrhosis; the liver shrinks.

• Cirrhosis: regenerative nodules surrounded by dense fibrosis.

• Portal hypertension (normal 5–10 mm Hg): prehepatic (portal vein thrombosis), intrahepatic (cirrhosis — the commonest — schistosomiasis), post-hepatic (hepatic venous obstruction). Varices, splenomegaly/hypersplenism, ascites, portosystemic encephalopathy.

• HCC: usually in cirrhosis; HBV and HCV; aflatoxin in subtropical regions; AFP and ultrasound screening in high-risk patients.

• Wilson disease: autosomal recessive (ATP7B, chromosome 13) — low ceruloplasmin, high urinary copper, Kayser-Fleischer rings; penicillamine. Haemochromatosis: HFE C282Y in over 80% — raised ferritin and transferrin saturation, liver disease, "bronze diabetes"; phlebotomy.

Gallbladder and Pancreas

• Gallstones: cholesterol stones > 85% in the West; black pigment stones are calcium bilirubinate. Risks: female sex, obesity, age. Acute cholecystitis: a stone blocks the cystic duct; Murphy sign. Gallbladder cancer: older women, gallstones in 69–95%; porcelain gallbladder is weakly linked.

• Acute pancreatitis: commonest triggers are gallstones and alcohol; diagnosis with amylase, lipase and imaging. Chronic pancreatitis: alcohol and smoking; calcification and duct stones; exocrine and endocrine failure.

Traps the Examiner Sets

• Gilbert = unconjugated (conjugation defect); dark urine = conjugated.

• IgM anti-HBc = acute; anti-HBs = immunity.

• Alcohol: AST:ALT ≥ 2, Mallory bodies, micronodular cirrhosis.

• Wilson = low ceruloplasmin + KF rings; haemochromatosis = high transferrin saturation.

Practice Questions (NEET PG pattern)

Original questions written in the style of the exam: +4 for a correct answer, −1 for a wrong one. Every answer was checked against the sources listed above. NEET PG papers are not published by NBEMS, so these are not past-paper questions.
