Management of Liver Cirrhosis.

Generally, liver damage from cirrhosis cannot be reversed, but treatment could stop or delay further progression and reduce complications. A healthy diet is encouraged, as cirrhosis may be an energy-consuming process. Close follow-up is often necessary. Antibiotics will be prescribed for infections, and various medications can help with itching. Laxatives, such as lactulose, decrease risk of constipation; their role in preventing encephalopathy is limited.

Treating underlying causes

Alcoholic cirrhosis caused by alcohol abuse is treated by abstaining from alcohol. Treatment for hepatitis-related cirrhosis involves medications used to treat the different types of hepatitis, such as interferon for viral hepatitis and corticosteroids for autoimmune hepatitis. Cirrhosis caused by Wilson's disease, in which copper builds up in organs, is treated with chelation therapy (e.g., penicillamine) to remove the copper.

Preventing further liver damage

Regardless of underlying cause of cirrhosis, alcohol and paracetamol, as well as other potentially damaging substances, are discouraged. Vaccination of susceptible patients should be considered for Hepatitis A and Hepatitis B.

Preventing complications

Ascites
Salt restriction is often necessary, as cirrhosis leads to accumulation of salt (sodium retention). Diuretics may be necessary to suppress ascites.

Esophageal variceal bleeding
For portal hypertension, propranolol is a commonly used agent to lower blood pressure over the portal system. In severe complications from portal hypertension, transjugular intrahepatic portosystemic shunting is occasionally indicated to relieve pressure on the portal vein. As this can worsen encephalopathy, it is reserved for those at low risk of encephalopathy, and is generally regarded only as a bridge to liver transplantation or as a palliative measure.

Hepatic encephalopathy
High-protein food increases the nitrogen balance, and would theoretically increase encephalopathy; in the past, this was therefore eliminated as much as possible from the diet. Recent studies show that this assumption was incorrect, and high-protein foods are even encouraged to maintain adequate nutrition.

Hepatorenal syndrome
The hepatorenal syndrome is defined as a urine sodium less than 10 mmol/L and a serum creatinine > 1.5 mg/dl (or 24 hour creatinine clearance less than 40 ml/min) after a trial of volume expansion without diuretics.

Spontaneous bacterial peritonitis
Cirrhotic patients with ascites are at risk of spontaneous bacterial peritonitis.

Transplantation

If complications cannot be controlled or when the liver ceases functioning, liver transplantation is necessary. Survival from liver transplantation has been improving over the 1990s, and the five-year survival rate is now around 80%, depending largely on the severity of disease and other medical problems in the recipient.[20] In the United States, the MELD score is used to prioritize patients for transplantation. Transplantation necessitates the use of immune suppressants (cyclosporine or tacrolimus).

Decompensated cirrhosis
In patients with previously stable cirrhosis, decompensation may occur due to various causes, such as constipation, infection (of any source), increased alcohol intake, medication, bleeding from esophageal varices or dehydration. It may take the form of any of the complications of cirrhosis listed above.

Patients with decompensated cirrhosis generally require admission to hospital, with close monitoring of the fluid balance, mental status, and emphasis on adequate nutrition and medical treatment - often with diuretics, antibiotics, laxatives and/or enemas, thiamine and occasionally steroids, acetylcysteine and pentoxifylline. Administration of saline is generally avoided as it would add to the already high total body sodium content that typically occurs in cirrhosis.
