Study Notes

Clinical Presentation of Cirrhosis

Detectable morphological liver changes include shrunken, enlarged, or normal size, sharp edge (irregular, smooth, or nodular surface), and firm consistency.
Symptoms stem from complications: portal hypertension (PH), hepatic decompensation (liver failure), and hepatocellular carcinoma (HCC).
Prognosis and treatment are influenced by the severity of these complications.

Portal Hypertension (PH)

PH is an early consequence of cirrhosis, crucial in developing several cirrhosis-related complications.
Develops irrespective of liver disease severity.
Clinical manifestations include:
- Portal-systemic shunting (PSS) leading to upper/lower GI bleeding, dilated abdominal wall veins, and caput medusa.
- Splenomegaly with possible left hypochondrial pain and hypersplenism.
- Ascites due to fluid transudation from intravascular compartments to the peritoneal cavity.

Hepatic Decompensation

Clinical cirrhosis is classified as compensated (absence of complications) or decompensated (presence of liver failure).
Compensated cirrhosis shows no past or present hepatic decompensation episodes.

Causes of Liver Cirrhosis

Viral hepatitis: B, C, and D.
Alcohol consumption.
Metabolic diseases:
- Non-alcoholic steatohepatitis (NASH)
- Hemochromatosis, Wilson disease, and more.
Prolonged cholestasis: Primary biliary cholangitis, primary sclerosing cholangitis.
Hepatic venous outflow obstruction: Budd-Chiari syndrome, cardiac cirrhosis.
Other: Autoimmune hepatitis, drugs (e.g., methotrexate, amiodarone), syphilis, cryptogenic causes.

Pathogenesis of Cirrhosis

Result of hepatic injury leading to fibrosis and regenerative nodules.
Fibrosis follows hepatocellular necrosis; fibrosis location varies with the cause (e.g., viral hepatitis in zone 1, alcoholism in zone 3).
Activated hepatic stellate cells (HSCs) deposit collagen, causing irreversible fibrosis.
Common blood findings include elevated bilirubin and GGT, with immunoglobulins often elevated due to impaired liver clearance.

Laboratory Findings

Anemia may present as normocytic, microcytic, or macrocytic due to varying causes.
Thrombocytopenia arises from hypersplenism and bone marrow suppression.
Other monitored parameters: renal function, serum electrolytes, serum alpha-fetoprotein (AFP).

Diagnosis

Specific tests for etiology include viral markers for hepatitis, transferrin and ferritin levels for hemochromatosis, and serum ceruloplasmin for Wilson disease.
Endoscopy to locate varices and sources of GI bleeding.
Regular HCC screening every six months through ultrasound and possible AFP testing.
Hepatic venous pressure gradient (HVPG) measurement helps evaluate PH.

Prognosis

Compensated cirrhosis: median survival time exceeds 12 years; significantly lower mortality without varices.
Transition to decompensated cirrhosis occurs at 5-7% per year, dropping median survival to about two years.
Poor prognostic indicators: refractory ascites, variceal bleeding, low MAP, high alcohol consumption, prothrombin time, bilirubin, alkaline phosphatase, low albumin, hyponatremia, infections.

Risk for HCC

Patients with cirrhosis have a 3-5% annual risk of developing HCC, particularly with alcohol and viral hepatitis-associated cirrhosis.

Prognostic Scoring Systems

Child-Pugh classification: assesses ascites, encephalopathy, serum albumin, bilirubin, and prothrombin time for short-term prognosis.
Model for End-stage Liver Disease (MELD): another scoring system for assessing liver disease severity.

General Function of Hepatic Cells

Sinusoidal endothelial cells (SECs) facilitate fluid and nutrient exchange.
Hepatic stellate cells (HSCs) are important for collagen deposition and are quiescent in a normal liver, activated during injury.
