Alpha(1)-Antitrypsin Deficiency

Abstract

Most of the care of liver disease in alpha(1)-antitrypsin (alpha(1)-AT) deficiency involves supportive management for complications of chronic liver disease including gastrointestinal bleeding, ascites, edema, encephalopathy, coagulation disturbances, spontaneous bacterial peritonitis, and hepatorenal syndrome. Some of these patients will have manifestations of cholestatic injury, including pruritus, hypercholesterolemia, and steatorrhea with fat-soluble vitamin deficiencies. The major challenge for the clinician taking care of these patients is the timing of referral for liver transplantation therapy. Timing of such referral is a relatively straightforward decision in alpha(1)-AT-deficient patients with progressive liver dysfunction. Some patients have nonprogressive or slowly progressing liver disease even after the development of cirrhosis or portal hypertension. Timing of liver transplantation in these patients should not be based simply on the presence of cirrhosis, portal hypertension or mild liver synthetic dysfunction, but rather on the basis of a subjective judgment by the hepatologist, patient, and family that manifestations of liver disease are interfering with overall life functioning.
