AIM:To investigate possible associations of anti-nuclear envelope antibody(ANEA)with disease severity and survival in Greek primary biliary cirrhosis(PBC)***:Serum samples were collected at diagnosis from 147 PBC patients(85%female),who were followed-up for a median 89.5 mo(range 1-240).ANEA were detected with indirect immunofluorescence on 1% formaldehyde fixed Hep2 cells,and anti-gp210 antibodies were detected using an enzyme linked immunosorbent *** were correlated with clinical data,histology,and ***:ANEA were detected in 69/147(46.9%) patients and 31/147(21%)were also anti-gp210 *** ANEA positive patients were at a more advanced histological stage(Ⅰ-Ⅱ/Ⅲ-Ⅳ56.5%/43.5% vs 74.4%/25.6%,P=0.005)compared to the ANEA negative *** had a higher antimitochondrial antibodies(AMA)titer(≤1:160/>1:160 50.7%/49.3%vs 71.8%/28.2%,P=0.001)and a lower survival time(91.7 ±50.7 mo vs 101.8±55 mo,P=0.043).Moreover,they had more advanced fibrosis,portal inflammation,interface hepatitis,and proliferation of bile ductules(P =0.008,P=0.008,P=0.019,and P=0.027,respectively).They also died more frequently of hepatic failure and/or hepatocellular carcinoma(P=0.016).ANEA positive,anti-gp210 positive patients had a difference in stage(Ⅰ-Ⅱ/Ⅲ-Ⅳ54.8%/45.2%vs 74.4%/25.6%,P= 0.006),AMA titer(≤1:160/>1:160 51.6%/48.4%vs 71.8%/28.2%,P=0.009),survival(91.1±52.9 mo vs 101.8±55 mo,P=0.009),and Mayo risk score(5.5 ±1.9 vs 5.04±1.3,P=0.04)compared to the ANEA negative *** positive,anti-gp210 negative patients had a difference in AMA titer(≤1:160/>1:160 50%/50%vs 71.8%/28.2%,P=0.002),stage(Ⅰ-Ⅱ/Ⅲ -Ⅳ57.9%/42.1%vs 74.4%/25.6%,P=0.033),fibrosis(P=0.009),portal inflammation(P=0.018),interface hepatitis(P=0.032),and proliferation of bile ductules(P=0.031).Anti-gp210 positive patients had a worse Mayo risk score(5.5±1.9 vs 4.9±1.7,P=0.038)than the anti-gp210 negative ***:The presence of ANEA and anti-gp210 identifies a subgroup of PBC pati
