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]
- Pohl's Index is if the AST/ALT ratio ≥1 and platelet count ≤ 150,000/mm3 then cirrhosis is very likely.[5]
- The Bonacini score is based on the ALT/AST ratio, platelet count, and INR.[6]
In diagnosis of cirrhosis (Ishak scores, 5-6) in patients with hepatitis C, the aspartate aminotransferase to platelet ratio index (APRI) ratio > 1 suggests cirrhosis with accuracy of:[8]
- Sensitivity = 79%
- Specificity = 78%
Complications
Clinical practice guidelines are available for the treatment of cirrhosis and its complications.[9]
Ascites
Esophageal varices
A clinical prediction rule is available to help detect patients at risk of esophageal varices.[10] For predicting clinically significant portal hypertension(hepatic venous pressure gradient ≥ 10 mmHg):[10]
At a cutoff value >0.06 the accuracy is:[10]
- Sensitivity 93%
- Specificity 61%
For predicting esophagel varices:[10]
- (spider angiomas = 1 if present and 0 if absent)
At a cutoff value >-1.02 the accuracy is:[10]
- Sensitivity 93%
- Specificity 37%
Patients with a thrombocytopenia and a palpable spleen are more likely to have large esophageal varices.[11][12] The cutoff for thrombocytopenia ranges from 40,000[12] to 150,000[11].
Treatment of bleeding
Transjugular intrahepatic portosystemic shunt may also add to endoscopic therapy for acute bleeding of esophageal varices.[13]
Emergency portacaval shunt may be a better treatment than endoscopic sclerotherapy.[14]
Prevention of bleeding
It is not clear that adding endoscopic band ligation to nadolol, an adrenergic_beta-antagonist, reduces bleeding.[15]
Hepatic encephalopathy
Hepatorenal syndrome
Spontaneous bacterial peritonitis
Spontaneous bacteremia
Spontaneous bacteremia may occur.[16][17] Mong patients with Child-Pugh Score indicating class C, half of bacteremias may not have a definite focus.[17]
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.
NAFLD fibrosis score
