Abstract
INTRODUCTION AND OBJECTIVES Little is known about primary biliary cholangitis (PBC) in non-whites. The purpose of this study was to evaluate clinical features and outcomes of PBC in a highly admixed population. MATERIAL AND METHODS The Brazilian Cholestasis Study Group multicentre database was reviewed to assess demographics, clinical features and treatment outcomes of Brazilian patients with PBC. RESULTS 562 patients (95% females, mean age 51 ± 11 years) with PBC were included. Concurrent autoimmune diseases and overlap with autoimmune hepatitis (AIH) occurred, respectively, in 18.9% and 14%. After a mean follow-up was 6.2 ± 5.3 years, 32% had cirrhosis, 7% underwent liver transplantation and 3% died of liver-related causes. 96% were treated with ursodeoxycholic acid (UDCA) and 12% required add-on therapy with fibrates, either bezafibrate, fenofibrate or ciprofibrate. Response to UDCA and to UDCA/fibrates therapy varied from 39%-67% and 42-61%, respectively, according to different validated criteria. Advanced histological stages and non-adherence to treatment were associated with primary non-response to UDCA, while lower baseline alkaline phosphatase (ALP) and aspartate aminotransferase (AST) levels correlated with better responses to both UDCA and UDCA/fibrates. CONCLUSIONS Clinical features of PBC in highly admixed Brazilians were similar to those reported in Caucasians and Asians, but with inferior rates of overlap syndrome with AIH. Response to UDCA was lower than expected and inversely associated with histological stage and baseline AST and ALP levels. Most of patients benefited from add-on fibrates, including ciprofibrate. A huge heterogeneity in response to UDCA therapy according to available international criteria was observed and reinforces the need of global standardization.

Hispanics with primary biliary cirrhosis are more likely to have features of autoimmune hepatitis and reduced response to ursodeoxycholic acid than non-Hispanics.

Abstract
BACKGROUND & AIMS Primary biliary cirrhosis (PBC) is a cholestatic disease that predominantly affects middle-aged Caucasian women. Studies have suggested that PBC has a more aggressive course in individuals of Hispanic ancestry. We investigated the clinical presentation and progression of PBC in an ethnically diverse population. METHODS We performed a cross-sectional study, analyzing data from Hispanic (n = 70) and non-Hispanic patients (n = 134) with PBC seen at the University of Miami/Jackson Memorial Hospital from January 1, 2000, through December 31, 2011. We compared demographics, clinical presentation, response to therapy, and outcomes between the groups. RESULTS Age at diagnosis, antimitochondrial antibody positivity, frequency of advanced histologic stage, use and dose of ursodeoxycholic acid (UDCA), and the presence of pruritus or fatigue were similar between groups. Hypothyroidism was less frequent among Hispanics (16% vs 29% in non-Hispanics; P = .04). Hispanic subjects were more likely to have overlap syndrome of PBC and autoimmune hepatitis than non-Hispanics (31% vs 13%; P = .002). After a median follow-up period of 3.65 years, a greater percentage of Hispanics had ascites (24% vs 12%; P = .03) and variceal bleeding (20% vs 7%; P = .01), although there were no differences in the number of deaths or liver transplants. Of 204 total patients, 180 received UDCA for at least 1 year. A lower proportion of Hispanic patients had a biochemical response to treatment (60% vs 88%; P < .0001). Independent predictors of poor biochemical response were younger age at diagnosis and Hispanic ethnicity. CONCLUSIONS In a cross-sectional study, patients of Hispanic ethnicity with PBC had an increased prevalence of overlap syndrome, reduced response to UDCA treatment, and more frequent complications of portal hypertension than non-Hispanic patients.
