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
Esophageal varices
A clinical prediction rule is available to help detect patients at risk.[6] For predicting clinically significant portal hypertension(hepatic venous pressure gradient ≥ 10 mmHg):[6]
At a cutoff value >0.06 the accuracy is:[6]
- Sensitivity 93%
- Specificity 61%
For predicting esophagel varices:[6]
- (spider angiomas = 1 if present and 0 if absent)
At a cutoff value >-1.02 the accuracy is:[6]
- Sensitivity 93%
- Specificity 37%
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].
Emergency portacaval shunt may be a better treatment than endoscopic sclerotherapy.[9]
Hepatic encephalopathy
Hepatorenal syndrome
Spontaneous bacterial peritonitis
Spontaneous bacteremia
Spontaneous bacteremia may occur.[10][11] Mong patients with Child-Pugh Score indicating class C, half of bacteremias may not have a definite focus.[11]
Prognosis
MELD Score
The MELD Score can help predict mortality. An online calculator is available.
Child-Pugh score
The Child-Pugh Score can help predict mortality. An online calculator is available.
