Concurrent Occurrence of Primary Biliary Cirrhosis and Rheumatoid Arthritis

Cureus. 2017 Aug 13;9(8):e1562. doi: 10.7759/cureus.1562.

Abstract

Primary biliary cirrhosis (PBC) is an autoimmune cholestatic disorder of the liver. A diagnostic serum marker for PBC is an anti-mitochondrial antibody. Most prominent histologic findings of PBC are portal inflammation and destruction of interlobular bile ducts. The PBC occurs only in 40 to 400 individuals per million in the general population. About 1.8 - 5.6% of individuals with this rare disorder have rheumatoid arthritis (RA). This case report describes a 56-year-old female with concurrent rheumatoid arthritis and primary biliary cirrhosis. The patients with RA are at higher risk of developing PBC compared to the general population. Thus, abnormal liver function test in the patients with RA, especially in the absence of alternative cause, warrants thorough investigation for PBC. Early diagnosis and treatment will improve the outcome of patients who develop PBC.
