Liver diseases in the elderly

The preceding discussions outline the various forms of cirrhosis that may be encountered in the elderly population. Cirrhosis is not uncommon in older patients. Although it has been stated that most cirrhosis in the elderly is due to alcohol, these assumptions are perhaps overestimations. In the authors' experience, many older patients are inappropriately labeled with alcoholic liver disease--presumed guilty until proven otherwise--and have subsequently been shown to have nonalcoholic liver disease. Careful investigation is required. Hepatotoxic drug exposure (e.g., to alpha methyldopa, nitrofurantoin, or isoniazid) should be ruled out, and hepatitis B and hepatitis C serology obtained. Primary biliary cirrhosis may occur in both sexes, and thus antimitochondrial antibody should be assayed. Severe heart disease may result in cardiac cirrhosis in the elderly, with ascites and hepatomegaly. Alpha 1-antitrypsin deficiency, primary sclerosing cholangitis, idiopathic hemochromatosis, and chronic autoimmune hepatitis may result in advanced cirrhosis in the elderly; appropriate serum studies should be obtained. If questions remain and if therapy may be changed, liver biopsy can be performed. A recent study suggested, however, that the risk of hemorrhage from liver biopsy in the elderly may be increased, especially if malignancy is present. The era of treatment for liver diseases has arrived. Colchicine, methotrexate, ursodeoxycholic acid, and others have shown promise in the treatment of PBC, primary sclerosing cholangitis, and alcoholic liver disease. Corticosteroids may be lifesaving in autoimmune liver disease. Phlebotomy remains the treatment of choice for hemochromatosis in any age group. Interferons and other antiviral agents are being used in chronic type B and type C hepatitis. Treatment of the complications of cirrhosis in the elderly may be safely accomplished. Advanced age is not a contraindication to variceal sclerotherapy. Vasopressin, however, may be contraindicated in the elderly patient if there is an underlying history of atherosclerotic coronary or peripheral vascular disease. Large-volume paracentesis and peritoneal venous shunting can afford symptomatic relief of ascites, even in the geriatric population. Finally, as noted previously, advanced age is no longer to be considered an absolute contraindication for liver transplantation. The evaluation of liver disease in the elderly may be diagnostically challenging, and its treatment rewarding.
