A male patient who developed late-onset primary biliary cirrhosis presenting with antinuclear envelope antibodies

Abstract

An 81-year-old man who had previously shown high levels of alkaline phosphatase (ALP), γ-glutamyltransferase (GTP), and total bilirubin presented with acute liver damage. He was positive for serum anti-gp210 and anti-p62 antibodies, but negative for serum antimitochondrial antibody. A liver biopsy revealed massive interstitial fibrosis and pseudolobulus, which were compatible with a diagnosis of primary biliary cirrhosis (PBC) at Scheuer's stage 4. He was given ursodeoxycolic acid at 600 mg/day. However, his condition deteriorated, and he eventually died of hepatic insufficiency in a state of malnutrition. We hypothesize that the presence of anti-gp210 and anti-p62 complex protein antibodies, rather than that of antimitochondrial antibodies, was correlated with the progression of PBC in this particular case.

Key words::

• Anti-gp210 antibody
• Antinuclear envelope antibody (ANEA)
• Anti-p62 complex antibody
• Primary biliary cirrhosis (PBC)
• Sjögren's syndrome (SS)
