Introduction: Little is known about primary biliary cholangitis (PBC) in Latin America, where this disease is thought to be rare. Objectives: To analyze clinical and biochemical features of Brazilian PBC patients. Methods: The Brazilian Cholestasis Study Group multicentre database was reviewed to assess demographics, clinical and laboratory features from PBC patients. Results: 562 patients with PBC were included; 80 (14.2%) had overlapping syndrome with autoimmune hepatitis and were excluded. Most subjects were middle-aged women (95%; mean age 51 ± 11 years) with classical symptoms of pruritus and/or fatigue (65%) and jaundice (22%). Mean time to diagnosis was 2.5 years. Prevalence of antimitochondrial (AMA) and antinuclear antibodies was 82.8% and 72.1%, respectively. Concurrent autoimmune diseases occurred in 18.9%, mainly Hashimoto's thyroiditis and Sjogren syndrome. Celiac disease was diagnosed in 1:80 (1.2%). Osteopenia and osteoporosis were demonstrated in 42% and 26%, respectively. Liver pathology at diagnosis was available for 326 patients (67.6%). One third of them had advanced PBC. After a mean follow-up of 6.2 ± 5.3 years, 32% of the subjects had clinical, laboratory or imaging evidence of cirrhosis. Requirement for liver transplantation and liver-related deaths were reported in 6.6% and 3.2% of the patients, respectively. Hepatocarcinoma was diagnosed in 1.9% of the subjects. Conclusion: A higher predominance of PBC among females, compared to other populations, was observed, while AMA positivity was lower. Concurrent autoimmune, celiac and bone diseases are common and should be adequately screened. Prolonged time to diagnosis and high prevalence of advanced liver disease might reflect difficulties in health care access in Brazil. |
