1.What is Cirrhosis
• Cirrhosis is a consequence of chronic liver disease, characterized by replacement of liver tissue by fibrosis, scar tissue and regenerative nodules leading to loss of liver function and disruption of the liver architecture.
2.Types of cirrhosis1.Micronodular cirrhosis.
• Regenerating nodules are usually <3 mm in size and the liver is involved uniformly.
• This type is often caused by ongoing alcohol damage or biliary tract disease
• 2. Macronodular Cirrhosis
• The nodules are of variable Size and normal acini may be seen within the larger nodules.
• This type is often seen following chronic viral hepatitis
3. Etiology
1. Drugs and toxins
Alcohol, methotrexate, isoniazid, methyldopa
2. infections
Hepatitis B and C , Schistosoma japonicum
3. autoimmune
PBC, autoimmune hepatitis, PSC
4. metabolic
Wilson’s disease, haemochromatosis, alpha 1 antitrypsin, porphyria
5. Biliary obstruction
Cystic fibrosis, atresia, strictures, gall stones
6. vascular
Chronic right heart failure, Budd Chiarisyndrome
7. miscellaneous
Sarcoidosis, intestinal by- pass surgery for obesity
8. unknown
cryptogenic
• Alcoholic liver disease 60-70%
• Viral hepatitis 10%
• Biliary disease 5-10%
• Primary hemochromatosis 5%
• Cryptogenic cirrhosis 10-15%
• Wilson’s, alpha 1AT def rare
4. Clinical presentation
Symptoms1. Non specific symptoms-
– Lethargy
– Malaise
– Abd pain
– loss of appetite
2. Symptoms due to elevated bilirubin-
– Yellowish discoloration of eyes
– Pruritus
3. Symptoms due to liver failure-
– Leg edema
– Abdominal distension
– Loss of hair
4. Symptoms due to complications
– Haemoptysis-UGI bleeding
– Altered behavior-HE
– Worsening abd pain-SBP

4. Investigations
• 1. Investigations for diagnosis
• 2. Investigations for etiology
• 3. Investigations for severity/complication
1. Investigations for diagnosis
1. USS abdomen
2. Liver biopsy
3. CT abdomen
2. Investigations for etiology
1.Viral hepatitis– Hepatitis B and C serology
2.Autoimmune hepatitis– Anti LKM antibody, anti smooth muscle antibody, IgG
3.Alpha 1 antitrypsin deficiency– Alpha 1 antitrypsin level, phenotype testing
4.Wilson’s disease– Reduced serum Cu and Caeruloplasmin; increased 24 hr
Cu excretion5.haemochromatosis
– s. ferritin6.Hepatocellular carcinoma
– Alpha feto protein level– USS
7.Primary billiary cirrhosis-serum IgM level
3. Investigations for severity/complication
1.liver function testsSerum Albumin
Coagulatory profile/PT
Serum billirubin
2.Liver biochemistryAST(SGOT)
ALT(SGPT)
ALP-biliary canaliculi damage
Gamma GT-hepatobilliary damage
3.Plt count-alcoholic thrombocytopaenia
4.UGI endoscopy-variceal bleeding
Hepatocellular damage
5.Peritoneal fluid analysis-SBP
6.USS-ascites, portal hypertension
7.Renal function tests(SE,S.cre)-hepatorenalsyndrome
5. Management
1.Supportive Management
2.Treatment for specific etiology
3.Treatment for complications
1.Supportive Management
1.Proper Nutrition
2.Manage bleeding-transfusion, fluid
3.Abdominal paracentesis
4.Tx for itching
5.Regular excersise
2.Treatment for specific etiology
1.Viral-antivirals
2.Alcohol-stop alcohol
3. Wilson's disease-chelation therapy
4.Billiary obstruction-relieve obstruction
5.Vascular-manage HF
