Abstract
Primary biliary cholangitis (PBC) is currently diagnosed at an early stage; therefore, the number of patients with PBC without symptoms at the time of diagnosis is increasing. However, up to 30% of patients with PBC exhibit the suboptimal response to ursodeoxycholic acid (UDCA) and are at high risk of end-stage liver disease. Obeticholic acid is an approved second-line therapy for patients with PBC that are refractory to UDCA. Novel surrogate endpoints are required to identify individuals eligible for second-line therapies. An inadequate biochemical response to UDCA is a useful predictor of poor outcomes in patients with PBC. In addition to UDCA effects on biochemical parameters, histological outcomes could be considered as candidate surrogate endpoints. Alterations in liver histology are used as surrogate endpoints in clinical studies. However, current staging systems are insufficient to determine PBC disease severity and progression because of the pathological heterogeneity of the disease. Histological features at baseline and biochemical response to UDCA treatment can affect the disease course of PBC. Therefore, novel surrogate endpoints must be represented by parameters characterized by histological outcomes and treatment responses in PBC. In this review, we discuss the existing histological parameters and newly created factors to identify patients with PBC who are at a high risk of developing end-stage liver disease and, consequently, the potential need for additional treatments.

Abstract
Primary biliary cirrhosis (PBC) is a chronic non-suppurative destructive intrahepatic cholangitis leading to cirrhosis after a protractive non cirrhotic stage. The etiology and pathogenesis are largely unknown and autoimmne mechanisms have been implicated to explain the pathological lesions. Many epitopes and autoantigens have been reported as crucial in the pathophysiology of the disease and T and B cells abnormalities have been described, the exact pathways leading to the destruction of small intrahepatic ductules are mostly speculative. In this review we examined the various epidemiologal and geoepidemiological data as well as the complex pathogenetic aspects of this disease, focusing on recent in vivo and in vitro studies in this field. Initiation and progression of PBC is believed to be a multifactorial process with strong infuences from the patient’s genetic background and by various environmental factors. The role of innate and adaptive immunity, including cytokines, chemokines, macrophages and the involvement of apoptosis and reactive oxygen species are outlined in detailed. The current pathogenetic aspects are presented and a novel pathogenetic theory unifying the accumulated clinical information with in vitro and in vivo data is formulated. A review of clinical manifestations and immunological and pathological diagnosis was presented. Treatment modalities, including the multiple mechanisms of action of ursodeoxycholate were finally discussed.

Abstract
Recently, our research team proposed a new histologic staging and grading system for primary biliary cirrhosis (PBC) that takes into account necroinflammatory activity and histologic heterogeneity. The present study aimed to confirm the usefulness of the new evaluation system. A total of 152 liver biopsy specimens and clinical data (including outcomes in patients with PBC before treatment with ursodeoxycholic acid) were analyzed with respect to the new system. Staging was evaluated on the basis of 3 histologic components (fibrosis, bile duct loss, and deposition of orcein-positive granules), and grading was assessed on the basis of chronic cholangitis activity and hepatitis activity. Concurrently, the classical systems, that is, the Scheuer and Ludwig staging systems, were also assessed and compared with our new system. PBC cases showed different distributions in each stage of the 3 systems. The new staging and grading system reflected liver dysfunctions before specific treatment. This was on a par with the results obtained using the classical systems. Development of cirrhosis-related conditions correlated well with the new staging system compared with the 2 classical staging systems, and in particular, the amount of deposition of orcein-positive granules could reflect development of cirrhosis-related conditions (scores 0-1 versus scores 2-3 groups, P < .0001). In conclusion, the new PBC staging system was demonstrated to reflect clinicolaboratory features, and its progression was associated with the development of cirrhosis-related conditions.
