Definition / general
  • Diffuse nodulation of liver due to fibrous bands subdividing liver into regenerative nodules
Epidemiology
Causes
  • Prevalence of causes varies by location
  • Common causes include
    • Chronic viral hepatitis B (± D) and C
    • Fatty liver disease: alcoholic and non alcoholic
    • Metabolic: genetic hemochromatosis, alpha-1-antitrypsin deficiency, Wilson disease
    • Immune mediated: autoimmune hepatitis, primary biliary cholangitis, primary sclerosing cholangitis
    • Chronic biliary obstruction
    • Drug induced liver injury
    • Cryptogenic (idiopathic) cirrhosis: accounts for 8 - 9% of liver transplants in the US; "burnt out" NAFLD / NASH is a common cause of cryptogenic cirrhosis (Hepatology 2000;32:689)
Pathophysiology
  • Combination of different processes (J Hepatol 2017;66:778)
    • Fibrosis: excessive production of collagen type I / III by hepatic stellate cells ± portal fibroblasts through chronic inflammation (TNF-alpha, TGF-beta, IL-1), cytokines from Kupffer cells, endothelial cells, bile duct cells, hepatocytes and disruption of extracellular matrix and toxins
    • Regeneration of hepatocytes through proliferation of progenitor cells of the ductular reaction
    • Parenchymal extinction due to vascular disruption
  • Regression (J Hepatol 2015;63:1038)
    • Cirrhosis is potentially reversible after successful treatment of chronic liver disease, e.g. viral hepatitis
    • Cessation of chronic damage allows hepatocyte recovery and modulates the microenvironment
    • Shifting balance from inflammation to resolution results in phenotypic adjustments of immune cells
    • Myofibroblasts are deactivated by senescence, apoptosis and inactivation
    • Matrix degradation also occurs

Regression of cirrhosis

Clinical features
  • General (nonspecific): malaise, fatigue, anorexia, weight loss
  • Specific (due to impaired liver function):
    • Impaired protein synthesis (leukonychia [white nails], ascites, bruising)
    • Impaired biliary excretion (jaundice, pruritus)
    • Impaired nitrogen metabolism (hepatic encephalopathy)
    • Impaired estrogen metabolism (palmar erythema, spider nevus, testicular atrophy, gynecomastia)
  • Complications:
    • Decompensation: development of jaundice, ascites, variceal hemorrhage or hepatic encephalopathy
    • Portal hypertension: ascites (± spontaneous bacterial peritonitis), splenomegaly, esophageal / gastric varices
    • Liver failure: coagulopathy, hepatic encephalopathy, hepatorenal syndrome, hepatopulmonary syndrome, portopulmonary hypertension
    • Hepatocellular carcinoma: cirrhosis is a key risk factor and the annual incidence of HCC among cirrhotic patients is 2 - 8% (Lancet 2014;384:2053, Hepatology 2010;51:1972)
Laboratory
  • Clinical subclassification of cirrhosis uses blood ± clinical parameters
  • Child-Pugh score / grade (J Hepatol 2005;42:S100)
    • Five parameters: albumin, bilirubin, INR / prothrombin time, ascites and hepatic encephalopathy
    • Each parameter is assigned from 1 - 3
    • Total score ranges from 5 - 15 and is categorized as grade A (5,6), B (7 - 9) and C (10 - 15)
  • Model for End stage Liver Disease (MELD) score (J Hepatol 2005;42:S100)
    • Three parameters: bilirubin, creatinine and INR
    • Uses to prioritize need for liver transplantation
  • Albumin-Bilirubin (ALBI) score / grade (J Clin Oncol 2015;33:550)
    • Two parameters: albumin, bilirubin
    • A simple, objective and evidence based alternative of Child Pugh score / grade

Micronodular and macronodular cirrhosis

Microscopic (histologic) description
  • Non biliary type cirrhosis
    • Diffuse disruption in architecture of the entire liver (loss of normal central-portal relationship)
    • Bridging fibrous septa
    • Roundish parenchymal nodules of regenerating hepatocytes
  • Biliary type cirrhosis
    • Diffuse disruption in architecture of the entire liver (loss of normal central-portal relationship)
    • Bridging fibrous septa
    • Irregular, jigsaw puzzle shaped parenchymal nodules of regenerating hepatocytes with peripheral pale halo (peripheral septal edema, loose packed fibrous tissue and chronic cholate stasis of periseptal hepatocytes)

Regression of cirrhosis

Differential diagnosis
Board review question #1
    What are the two factor(s) contributing to the periseptal halo in biliary type cirrhosis?

  1. Ballooning degeneration
  2. Bilirubinostasis
  3. Feathery degeneration
  4. Florid duct lesion
  5. Periseptal edema
Board review answer #1
C. and E.

  1. Ballooning degeneration is a hallmark pathological change of steatohepatitis, which is not associated with biliary type cirrhosis.
  2. Bilirubinostasis may be present in late biliary type cirrhosis but is not associated with periseptal halo.
  3. Feathery degeneration is one of features of chronic cholate stasis contributing to the periseptal halo in biliary type cirrhosis.
  4. Florid duct lesion is one of characteristic features of primary biliary cholangitis, which is not associated with periseptal halo.
  5. Periseptal edema is one of characteristic features of biliary type cirrhosis, which is not associated with periseptal halo.
