The arthritis of primary biliary cirrhosis: clinical features and associated immune processes.

: We have performed a survey to determine the percentage of patients with primary biliary cirrhosis (PBC) and arthritis followed at Geisinger Clinic, a rural tertiary care center. We have assessed the clinical features of the arthritis, delineated any signs that suggest the diagnosis of asymptomatic PBC in patients with arthritis, and explored coexisting immune diseases.From January 1988 through November 1993, 36 patients with PBC were identified from a computer search of the Geisinger Gastroenterology Clinic database. These records were reviewed for clinical information of an associated arthritis, other autoimmune processes, and demographic information.Twenty-five percent of the patients with PBC had an inflammatory arthritis. Two patients had classic, seropositive rheumatoid arthritis with erosions and nodules. The remaining seven patients had a predominantly symmetrical, nonnodular inflammatory arthritis involving both large and small joints. Tenosynovitis was the most common presenting rheumatic feature. Sjogren's syndrome, Raynaud's phenomenon, and hypothyroidism were more common in the subgroup of PBC patients with arthritis.A diagnosis of PBC should be considered in any patient presenting with tenosynovitis or an unexplained inflammatory arthritis, especially in the setting of Raynaud's phenomenon and signs of Sjogren's syndrome.
