Primary biliary cirrhosis (PBC) is a cholestatic liver disease, which is characterized by a chronic inflammatory destruction of intrahepatic bile ducts. It is a rare disorder whose precise etiology is still to be elucidated. Even though the liver is the principal target of PBC, other organ systems also might be affected. Muscular involvement has rarely been described in this disease, and in the majority of cases, muscular weakness has been interpreted as polymyositis. We report the case of a 48-year-old woman suffering from classic PBC, in association with a myopathy whose histological features are distinct from the cases reported before. We also performed a MEDLINE research for PBC and concomitant muscular diseases.

Primary biliary cirrhosis (PBC) is a progressive autoimmune disease of the liver. It is the most common cause of chronic intrahepatic cholestatic liver disease in adults. This review addresses the epidemiology, etiology and genetics, pathophysiology and pathogenesis, diagnosis, differential diagnosis, treatment, complications, and prognosis of PBC. Figures show the pathogenesis and natural history of PBC and histologic features of the four stages of PBC. Tables list diagnostic criteria for PBC via the American Association for the Study of Liver Diseases, differential diagnosis for PBC, medications used to treat PBC, secondary therapy for PBC, and follow-up of patients with PBC. This review contains 2 highly rendered figures, 5 tables, and 45 references.

1. Primary biliary cirrhosis is a chronic cholestatic liver disease with an autoimmune aetiology. The classical histopathological lesion, of portal tract biliary epithelial cell damage, is accompanied by a T-cell-rich mononuclear cell infiltrate and upregulation of cell surface markers suggestive of local T-cell activation and cytokine release. This suggests that T-cell mediated mechanisms play an important role in tissue damage in primary biliary cirrhosis. 2. CD4+ T-cells specific for the E2 component of human pyruvate dehydrogenase complex (PDC-E2), a highly conserved enzyme which plays a critical role in intermediate metabolism, are present in the peripheral repertoire of the majority of patients with primary biliary cirrhosis. These cells are almost entirely absent from normal and chronic liver disease control subjects. The observations that peripheral blood PDC-E2-specific cells are most commonly seen in early stage disease, when active bile duct damage is occurring, and that PDC-E2-specific cells can be found in the portal tract infiltrate at times when this damage is occurring, suggest that these autoreactive cells may have a role to play in the aetiology of primary biliary cirrhosis. 3. T-cells specific for the whole PDC and its E1 component are seen in significant numbers of normal control subjects as well as patients with primary biliary cirrhosis. Retention of potentially autoreactive cells in the normal T-cell repertoire has been reported for a number of other autoantigens. 4. T-cell epitopes appear to be widely distributed throughout PDC-E2. This is in contrast to the B-cell epitopes which are highly restricted to the inner lipoyl binding domain of the protein.

Tract Infections

Recurrent urinary tract infections (UTI) have been considered potential triggers of primary biliary cirrhosis (PBC), an autoimmune cholestatic liver disease characterised by progressive destruction of intrahepatic bile ducts. Additional support for the link made between PBC and UTI was based on early observations of recurrent episodes of bacteriuria in female patients with PBC. A series of large epidemiological studies demonstrated a strong correlation between recurrent UTI and PBC, initiating a series of studies investigating the role ofEscherichia coli(E. coli, the most prevalent organism isolated in women with UTI) as a trigger of PBC. Immunological evidence of B- and T-cell cross-reactive responses implicating PBC-specific autoantigens andE. colimimics have been clearly demonstrated, adding support to the notion thatE. coliis a potential infectious inducer of PBC in susceptible individuals. One of the major limitations in proving theE. coli/PBC association was the lack of reliableE. coli-infected animal models of PBC. This review provides an overview of the evidence linking this infectious agent with PBC and discusses the pros and cons of a recently developedE. coli-infected animal model of PBC.

The purpose of the present review is to discuss the diagnosis and management of cholestatic liver diseases. Differential diagnoses to consider are described, including causes of extrahepatic biliary obstruction such as gallstones, strictures, extrabiliary malignancies and pancreatitis. In addition, diseases that cause intrahepatic cholestasis such as primary biliary cirrhosis, primary sclerosing cholangitis, hepatocellular diseases and a variety of miscellaneous causes including drugs that may cause cholestasis are discussed. Primary biliary cirrhosis and primary sclerosing cholangitis are reviewed in detail, and management options are identified. The prognosis of patients with these diseases is discussed, and the Mayo Mathematical Models in Cholestatic Liver Disease for both primary biliary cirrhosis and primary sclerosing cholangitis are provided. Finally, management options for the complications of cholestasis are provided.

Autoimmune Pathogenesis

Primary biliary cirrhosis (PBC) is a chronic cholestatic liver disease characterized serologically by the high prevalence of anti-mitochondrial autoantibodies (AMAs) and histologically by the cholangitis of small bile ducts, eventually followed by extensive loss of the small bile duct. An autoimmune pathogenesis is suggested by clinical and experimental studies, but there remain issues regarding the etiology, the significance of AMAs in the pathogenesis of bile duct lesions, and so on. The unique properties of apoptosis in biliary epithelial cells (BECs), in which there is exposure of autoantigen to the effectors of the immune system, are proposed to be a cause of bile duct lesions in PBC. Recent progress disclosed that cellular senescence and autophagy are involved in bile duct lesions in PBC. Senescent BECs may modulate the periductal microenvironment by expressing senescence-associated secretory phenotypes, including various chemokines, and contribute to the pathogenesis of bile duct lesions in PBC.

Disease Specific

Primary biliary cirrhosis (PBC) is a cholestatic liver disease of autoimmune origin, characterised by the destruction of small intrahepatic bile ducts. The disease has an unpredictable clinical course but may progress to fibrosis and cirrhosis. The diagnostic hallmark of PBC is the presence of disease-specific antimitochondrial antibodies (AMA), which are pathognomonic for the development of PBC. The disease overwhelmingly affects females, with some cases of male PBC being reported. The reasons underlying the low incidence of males with PBC are largely unknown. Epidemiological studies estimate that approximately 7–11% of PBC patients are males. There does not appear to be any histological, serological, or biochemical differences between male and female PBC, although the symptomatology may differ, with males being at higher risk of life-threatening complications such as gastrointestinal bleeding and hepatoma. Studies on X chromosome and sex hormones are of interest when studying the low preponderance of PBC in males; however, these studies are far from conclusive. This paper will critically analyze the literature surrounding PBC in males.
