ABSTRACT Two cases of scleroderma and primary biliary cirrhosis are described. One had systemic sclerosis with primary biliary cirrhosis of six years' duration at the stage of ductular proliferation. The other had the C.R.S.T. syndrome (calcinosis, Raynaud's phenomenon, sclerodactyly, and telangiectases) with primary biliary cirrhosis at the florid stage. Several similar cases were found in a review of other reports, and it is suggested that the association may be due to a common "autoimmune" process.

    ABSTRACT: Primary biliary cirrhosis (PBC) can be complicated by systemic sclerosis (SSc) and more specifically, limited cutaneous SSc (lcSSc), which was previously called CREST syndrome. Moreover, combined PBC and SSc has been described in many case reports. Although neither the etiology of PBC nor that of SSc has been elucidated, some genetic and immunological factors are known to be shared. Both disorders are autoimmune fibrotic diseases characterized by increased levels of pro-fibrotic cytokines transforming growth factor β (TGFβ) and IL-6, which have recently been suggested to influence Th17 cells and regulatory T cells involved in acquired immunity. LcSSc is accompanied by CREST symptoms, although complete CREST cases are rare, with relatively high prevalence of Raynaud's phenomenon, sclerodactyly and telangiectasia, and lower prevalence of calcinosis and esophageal dysmotility. Because patients with anti-centromere antibody-positive PBC-SSc are at a high risk of developing portal hypertension, particular attention should be paid to the management of gastroesophageal varices. In addition, the management of SSc-related non-hepatic disorders, such as pulmonary fibrosis, pulmonary hypertension, heart disorder, infection and malignancy, is also important for improved outcomes. Since PBC is often complicated by rheumatic disease, hepatologists should keep the possibility of systemic disorder in mind when examining PBC patients.

    ABSTRACT: Primary biliary cirrhosis (PBC) is an autoimmune disease of the liver characterised by biochemical evidence of cholestasis, elevated alkaline phosphatase levels and the presence of the highly disease specific anti-mitochondrial autoantibodies. Extra-hepatic autoimmune manifestations are common, including rheumatic disorders, such as systemic sclerosis (SSc). Notably, PBC is the most frequent autoimmune liver disease in SSc patients. Based on skin lesion extension, two major SSc disease subgroups are recognised: limited cutaneous SSc (lSSc) and diffuse cutaneous SSc. Anti-centromere antibody (ACA) positivity is highly characteristic of SSc, with up to 90% prevalence in lSSc patients. ACA has also been found in up to 30% of PBC patients and 80% of patients with a PBC/SSc overlap syndrome. The diagnostic and clinical significance of ACA positivity in patients with PBC without SSc has recently been under investigation, with several studies highlighting links to severe bile duct injury and portal hypertension. This review discusses the diagnostic and clinical relevance of ACA in patients with PBC, with or without SSc.

    ABSTRACT: OBJECTIVE: To investigate the prevalence of primary biliary cirrhosis (PBC) and PBC-associated autoantibodies in Japanese systemic sclerosis (SSc) patients. METHODS: Clinical data from 225 Japanese SSc patients were retrospectively obtained. Serum samples from these patients were examined for PBC-associated autoantibodies, anti-mitochondrial M2 antibodies (AMA), anti-sp100 antibodies (anti-sp100), and anti-gp210 antibodies (anti-gp210) by enzyme-linked immunosorbent assay. RESULTS: Of 225 patients, 37 (16.4%) had AMA, 13 (5.8%) had anti-sp100, and 3 (1.3%) had anti-gp210. Three patients were positive for both AMA and anti-sp100, and 2 were positive for both AMA and anti-gp210. PBC was found in 22 (9.8%) patients positive for AMA with or without anti-sp100 or anti-gp210, but not in those with anti-sp100 or anti-gp210 without AMA. Furthermore, 13 patients lacking these three antibodies were diagnosed with or suspected of PBC by liver biopsy and/or their clinical manifestation. Multivariable analysis revealed that AMA and anti-centromere antibodies were independently associated with PBC in SSc patients, while anti-sp100 and anti-gp210 were not. CONCLUSIONS: This study has demonstrated even higher prevalence of both PBC-associated autoantibodies and PBC in the Japanese SSc population than in the Caucasian SSc population. AMA and anti-centromere antibodies are likely to indicate increasing risk of PBC in SSc patients.
