title: Traditional management of liver disorders.
abstract: Dietary measures have achieved mixed results in the management of liver disorders. Although a high energy diet may shorten the course of viral hepatitis by a relatively small amount, dietary restriction is usually of no benefit in compensated cirrhosis. Restriction of sodium intake to 22 to 60 mol/day leads to resolution of cirrhotic ascites in approximately 20% of patients, and reduces the requirement for diuretics in the remainder. In advanced liver disease, diet plays an important role in the avoidance of portal-systemic encephalopathy (PSE), with the tolerance of most nutrients, most importantly protein, being sharply reduced. Despite the frequent presence of carbohydrate intolerance in liver disease, carbohydrate supplementation may be required to ensure adequate utilisation of the reduced dietary protein intake. Zinc supplementation may also be required in liver cirrhosis to compensate for a deficiency. Bed rest is an important component of the management of acute and chronic liver disorders, together with the avoidance of fatigue. Abstinence from alcohol is required in alcoholic liver disease patients, who should receive parenteral thiamine 100 mg and other vitamin and mineral supplementation as required. Agents acting on the ascending loop of Henle [such as furosemide (frusemide)] or the distal tubule (such as spironolactone) are the diuretics most frequently employed to mobilise ascites in cirrhosis, the latter drug being the more effective in nonazotaemic patients. In the absence of oedema, the diuresis should be restricted to a maximum of 750 ml/day; however, patients with oedema may safely undergo a diuresis of less than or equal to 1.5 L/day. Diuretic therapy is often associated with renal complications, such as azotaemia (usually reversible) and severe hyponatraemia in cirrhotic patients with ascites; spironolactone may produce antiandrogenic adverse effects. Lactulose, used in the treatment of acute and chronic PSE, acts by inhibiting gastrointestinal absorption of ammonia and other toxic nitrogenous substances, and by reducing urea degradation. Other pharmacological treatments, such as branched-chain amino acids and benzodiazepine antagonists have a limited role in the management of PSE. Chronic cholestasis has been treated with cholestyramine and fat-soluble vitamins, whereas ursodeoxycholic acid appears to be a promising agent in the treatment of primary biliary cirrhosis. In chronic hepatitis, the prevention of development of cirrhosis is a primary treatment goal which has been attempted with variable success using antifibrotic drugs such as penicillamine and colchicine.(ABSTRACT TRUNCATED AT 400 WORDS)
