Cirrhosis By Dr. Afework Adam(MD,GP) 1 Dr.Afework A 10/8/2025
Outlines Introduction Pathophysiology of cirrhosis Evaluation of severity Complication of cirrhosis 2 10/8/2025 Dr.Afework A
cirrhosis Is development of fibrosis with architectural distortion and the formation of regenerative nodules Could be reversible 3 10/8/2025 Dr.Afework A
….cont Liver fibrosis is a dynamic process that results from an imbalance between the production and dissolution of the extracellular matrix Result of the progressive accumulation and decreased remodeling of the ECM, which disrupts the normal architecture of the liver. Progression to cirrhosis or regression no approved anti-fibrotic drug 10/8/2025 Dr.Afework A 4
Cirrhosis Advanced fibrosis, scarring, and formation of regenerative nodules leading to architectural distortion. A number of etiologies with common pathologic features: degeneration and necrosis of hepatocytes , and replacement of liver parenchyma by fibrotic tissues and regenerative nodules , and loss of liver function. 5 10/8/2025 Dr.Afework A
Causes of cirrhosis 6 10/8/2025 Dr.Afework A
Risk factors for alcoholic liver disease Quantity Ingestion of 160 g/d is associated with 25–fold increased risk of developing alcoholic cirrhosis duration of alcohol intake --- 10yrs Sex- female >male Genetic Coinfection : HCV,HBV 7 10/8/2025 Dr.Afework A
1.alcoholic fatty liver benign right upper quadrant discomfort tender hepatomegaly Nausea jaundice Reversible with cessation alcohol intake 10 10/8/2025 Dr.Afework A
2.Alcoholic hepatitis Cytokine production is responsible for the systemic manifestations of alcoholic hepatitis Fever, spider nevi, jaundice, and abdominal pain Portal hypertension, ascites , or variceal bleeding can occur in the absence of cirrhosis Precursor for alcoholic cirrhosis Reversible with cessation of alcohol intake AST>ALT 11 10/8/2025 Dr.Afework A
12 10/8/2025 Dr.Afework A
Post hepatitis : HBV,HCV 80% of acute HCV develop chronic hepatitis C 20–30% will develop cirrhosis over 20–30 years 5% of acute HBV develop chronic hepatitis B 20% -25%of those patients will go on to develop cirrhosis. 13 10/8/2025 Dr.Afework A
Cirrhosis from Autoimmune Hepatitis Post hepatitis antinuclear antibody (ANA) anti-smooth-muscle antibody (ASMA) 14 10/8/2025 Dr.Afework A
nonalcoholic steatohepatitis (NASH) Fatty liver:- DM, Dyslipidemia, obesity, drugs nonalcoholic steatohepatitis can progress to cirrhosis cryptogenic cirrhosis: nonalcoholic steatohepatitis As their cirrhosis progresses, they become catabolic and then lose signs of steatosis 15 10/8/2025 Dr.Afework A
Cardiac Cirrhosis long-standing right-sided congestive heart failure may develop chronic liver injury and cardiac cirrhosis-- Corpulmonale Back ward transmission of elevated venous pressure via the inferior vena cava and hepatic veins to the sinusoids of the liver Nutmeg liver Corpulmonale —hepatic congestion– compress vessel— heamorrhegic ischemia(Nutmeg liver) 16 10/8/2025 Dr.Afework A
s/s signs of congestive heart failure an enlarged firm liver ALP levels are characteristically elevated aminotransferases may be normal or slightly increased with AST usually higher than ALT AST>ALT- Alcoholic hepatitis - Cardiac cirrhosis Enlarged liver—cardiac cirrhosis --HIV 17 10/8/2025 Dr.Afework A
Diagnosis of cirrhosis Although cirrhosis is strictly speaking a histologic diagnosis, a combination of clinical, laboratory, and imaging features can help confirm a diagnosis of cirrhosis. Several physical findings suggestive of cirrhosis result in part from alterations in the metabolism of estrogen by the cirrhotic liver . An intense red coloration of the thenar and hypothenar eminences suggests palmar erythema . Terry’s nails are characterized by proximal nail bed pallor, which can also involve the entire nail plate, with predominant involvement of the thumb and index finger. Clubbing of the fingernails may result from the presence of arteriovenous shunts in the lung as a result of portal hypertension.
Gynecomastia is the enlargement of the male breast with palpable tissue. Spider telangiectasias (or angiomata ) are dilated arterioles characterized by a prominent central arteriole with radiating vessels. Compression of the central arteriole with a pinhead results in blanching followed by reformation of the “spider” after release of pressure on the arteriole. In general, more than 2 to 3 spider telangiectasias are considered abnormal.
Dilated abdominal veins ( caput medusae ) with flow away from the umbilicus, toward the inferior vena cava in the infraumbilical area and toward the superior vena cava in the supraumbilical area, suggest intrahepatic portal hypertension On the other hand, dilatation of veins in the flank with blood draining toward the superior vena cava suggests inferior vena caval obstruction. Parotid enlargement is also a feature of cirrhosis, especially alcoholic cirrhosis. Usually secondary to fatty infiltration , fibrosis, and edema rather than a hyperfunctioning gland
Dupuytren's contracture- Nodular fibrosing lesions with bands radiating distally The ulnar side of the hand is affected, with the fourth and fifth fingers usually involved first.
Evaluation of severity of cirrhosis 28 10/8/2025 Dr.Afework A
Complication of cirrhosis 29 10/8/2025 Dr.Afework A
Portal Hypertension Portal circulation -a high compliance, low-resistance system that is able to accommodate a large blood volume -dual blood supply *75% portal v *25% hepatic a 30 10/8/2025 Dr.Afework A
Portal Hypertension Portal pressure gradient >5 mm Hg. Normal HVPG is 3-5 mmHg. a measure of sinusoidal pressure Initial and main consequence of cirrhosis. Responsible for the majority of its complications. May occur before a formal anatomical diagnosis of cirrhosis is established. 31 10/8/2025 Dr.Afework A
Pathophysiology of PH in cirrhosis Increased intrahepatic resistance due to cirrhosis and regenerative nodules and active intrahepatic vasoconstriction Structural in 70%, functional in 1/3 rd Increased splanchnic blood flow secondary to vasodilatation within the splanchnic vascular bed. Increases in portal resistance or portal flow can contribute to increased pressure. OHM’ ҆ S LAW: Δ P = F × R PHN almost always results from increases in both portal resistance and portal flow 32 10/8/2025 Dr.Afework A
Measurement of PH Direct Portal Vein Pressure Indirect HVPG only sinusoidal and postsinusoidal TE/MRE US 33 10/8/2025 Dr.Afework A
Non-invasive History and physical examination IX: Lab evidence of hepatic dysfunction Low platelet count Ultrasound, Fibroscan, MRE.. Esophagogastroduodenoscopy(EGD) 34 10/8/2025 Dr.Afework A
….PH Imaging- Ultrasound, CT, MRI Recanalized paraumbilical vein, spontaneous splenorenal circulation, and dilated left and short gastric veins. Portal vein diameter >13 mm, reduction of portal vein velocity. A reversal of flow within the portal system is 100% specific and sufficient to diagnose CSPH. Splenomegaly: sensitive but not specific. 35 10/8/2025 Dr.Afework A
….PH -pre-hepatic -intra-hepatic -post-hepatic 36 10/8/2025 Dr.Afework A
Ascites The most common complication of cirrhosis Cirrhosis is the most common cause of ascites i [~ 85 %]. 5 – 10% of patients with compensated cirrhosis per yr Poor prognosis (5-year survival~30%) Uncomplicated not infected, refractory or associated with impairment of renal function. 37 10/8/2025 Dr.Afework A
