Cirrhosis is a "liver disease in which the normal microcirculation, the gross vascular anatomy, and the hepatic architecture have been variably destroyed and altered with fibrous septa surrounding regenerated or regenerating parenchymal nodules."[1]

Cause / etiology

The two most common causes, at least in women, may be alcoholism which causes alcoholic hepatitis and obesity with causes steatohepatitis.[2] These two risks may have a "supra-additive interaction."[3]

Diagnosis

Clinical prediction rules exist to help diagnosis cirrhosis.[4] If the AST/ALT ratio ≥1 and platelet count ≤ 150,000/mm3 (Pohl's Index) then cirrhosis is very likely.[4]

Complications

Clinical practice guidelines are available for the treatment of cirrhosis and its complications.[5]

Ascites

For more information, see: Ascites.


Esophageal varices

A clinical prediction rule is available to help detect patients at risk of esophageal varices.[6] For predicting clinically significant portal hypertension(hepatic venous pressure gradient ≥ 10 mmHg):[6]

Risk score = -0.193 + (-0.359*albumin) + (16.456*INR) + (-0.0016*ALT)

At a cutoff value >0.06 the accuracy is:[6]

For predicting esophagel varices:[6]

(spider angiomas = 1 if present and 0 if absent)

At a cutoff value >-1.02 the accuracy is:[6]

Patients with a thrombocytopenia and a palpable spleen are more likely to have large esophageal varices.[7][8] The cutoff for thrombocytopenia ranges from 40,000[8] to 150,000[7].

Transjugular intrahepatic portosystemic shunt may also add to endoscopic therapy for acute bleeding of esophageal varices.[9]

Emergency portacaval shunt may be a better treatment than endoscopic sclerotherapy.[10]

Hepatic encephalopathy

For more information, see: Hepatic encephalopathy.


Hepatorenal syndrome

For more information, see: Hepatorenal syndrome.


Spontaneous bacterial peritonitis

For more information, see: Spontaneous bacterial peritonitis.


Spontaneous bacteremia

Spontaneous bacteremia may occur.[11][12] Mong patients with Child-Pugh Score indicating class C, half of bacteremias may not have a definite focus.[12]

Prognosis

MELD Score

For more information, see: MELD Score.

The MELD Score can help predict mortality. An online calculator is available.

Child-Pugh score

For more information, see: Child-Pugh Score.

The Child-Pugh Score can help predict mortality. An online calculator is available.
