Antimitochondrial antibody profiles in patients with primary biliary cirrhosis before orthotopic liver transplantation and titres of antimitochondrial antibody-subtypes after transplantation

J Hepatol. 1994 Feb;20(2):181-9. doi: 10.1016/s0168-8278(05)80056-x.


Four antimitochondrial antibody profiles (A-D) have been defined in primary biliary cirrhosis according to the presence of antibodies to M2, M4, M8, and M9 in ELISA and the complement fixation test: A: anti-M9 positive in ELISA and western blot, B: anti-M9 and/or anti-M2 positive in ELISA, C: anti-M2, -M4 and/or -M8 positive in ELISA, D: anti-M2, -M4, and/or -M8 positive in ELISA and complement fixation test. These profiles predict the outcome of primary biliary cirrhosis in the early stages and reflect differences in the natural course of the disease (benign versus progressive). In this study sera from 29 patients with advanced primary biliary cirrhosis who had received liver transplant were retested before and after orthotopic liver transplantation. Twenty-eight were antimitochondrial antibody/anti-M2 positive, and one patient had only antibodies to nuclear dots in the immunofluorescence test on cell cultures. When the antimitochondrial antibody-profiles in these 28 anti-M2 positive patients were analysed, it became evident that 26 of them belonged to subgroup C or D before orthotopic liver transplantation. Two patients had profile B; one had high titres of antinuclear and smooth muscle antibodies indicating an overlap syndrome between primary biliary cirrhosis and autoimmune chronic active hepatitis. The other patient had antibodies to nuclear dots in association with anti-M2. None of the patients had profile A. Antibody titres were studied after orthotopic liver transplantation in 23 of the 28 patients who survived for 1 to 13 years.(ABSTRACT TRUNCATED AT 250 WORDS)
