Background: Several studies described the cross-sectional characteristics of systemic sclerosis patients and coexisting primary biliary cholangitis, but longitudinal prognostic data are lacking., Aims: To describe the systemic sclerosis-primary biliary cholangitis phenotype, including baseline characteristics and outcomes., Methods: We performed a multicentre the European Scleroderma Trials and Research Group study of systemic sclerosis patients with primary biliary cholangitis or with primary biliary cholangitis-specific antibodies, matched with systemic sclerosis controls free from hepatobiliary involvement matched for disease duration and cutaneous subset. Data were recorded at baseline and at the last available visit., Results: A total of 261 patients were enrolled (115 primary biliary cholangitis-systemic sclerosis, 161 systemic sclerosis). At baseline, systemic sclerosis-primary biliary cholangitis patients had a higher prevalence of anti-centromere antibodies ( p  = 0.0023) and a lower prevalence of complete absence of digital ulcers. The milder vascular involvement was confirmed at follow-up when crucial differences emerged in the percentage of patients experiencing digital ulcers; a significantly higher number of patients who never experienced digital ulcers were observed among primary biliary cholangitis-systemic sclerosis patients ( p  = 0.0015). Moreover, a greater incidence of pulmonary arterial hypertension ( p  < 0.001) and of conduction blocks ( p  = 0.0256) was observed in systemic sclerosis patients without primary biliary cholangitis. Patients with primary biliary cholangitis had higher levels of liver enzymes at baseline than systemic sclerosis patients; a significant decrease in liver enzymes was observed at follow-up. Out of 18 patients with cholangitis, one received a liver transplant at follow-up., Conclusion: Our data show that systemic sclerosis-primary biliary cholangitis exhibit a mild systemic sclerosis and primary biliary cholangitis phenotype with outcomes being in general favourable., Competing Interests: The author(s) declared the following potential conflicts of interest with respect to the research, authorship and/or publication of this article: G.L., P.A., O.D., K.A., Y.B.-M., E.H., A.B.-G., E.D.L., S.R., F.I., E.R., L.G., R.I., S.B.-R., L.G., L.B., C.B., S.M., P.N., I.S., D.K., V.C., U.A.W., C.M., S.G., M.-E.T., L.T., G.C., M.K., M.M.-C. and Y.A. have no conflict of interests (COIs) to declare.
