Hepatitis with Australia antigenemia following renal transplantation

Over a seven-year period 18 of 125 patients who underwent renal transplantation developed hepatitis. Acute hepatic necrosis occurred in two, chronic aggressive hepatitis progressing to posthepatitic cirrhosis in eight, chronic persistent hepatitis in five, acute hepatitis with recovery in two and cholestatic hepatitis in one. Hepatic failure was the cause of death in four and a major contributing factor in three. Fifteen of the 18 were of blood Group A. After renal transplantation Australia antigen (Au) was present in the blood of 12 of the 15 patients with hepatitis who were tested and in one of 38 patients without clinical evidence of liver disease. Once present, Au persisted in all patients but one. Particles measuring 210 to 250 A, characteristic of Au, were seen in liver cells by electronmicroscopy in nine of the 10 patients examined who had hepatitis with Australia antigenemia, but they were not seen in the two patients studied with Au-negative hepatitis.
