[PMID: 38670320 DOI: 10.1016/j.jhep.2024.04.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Revised: 03/19/2024] [Accepted: 04/12/2024] [Indexed: 04/28/2024]
Abstract
Patient reported outcomes (PROs) such as health related quality of life (HRQL) are important outcome measures for patients with chronic liver diseases (CLDs). Presence of cirrhosis and advanced liver disease have been associated with worsened HRQL and fatigue. On the other hand, some patients with earlier stages of CLD such as primary biliary cholangitis (PBC), chronic hepatitis C viral infection (HCV) and Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD), also experience fatigue causing PRO impairment. Treatment for some CLDs may improve HRQL and, sometimes, levels of fatigue. We aimed to provide an in-depth expert review of concepts related to fatigue and HRQL in patients with PBC, HCV and MASLD. As such, a panel of experts in fatigue and CLD reviewed and discussed the literature and collaborated to provide this expert review of fatigue in CLD. Herein, we review and report on the complexity of fatigue highlighting that fatigue is comprised of peripheral (neuromuscular failure, often in conjunction with sub-maximal cardiorespiratory function) and central (central nervous system dysfunction) causes. Fatigue and HRQL are measured using validated self-report instruments. Additionally, fatigue can be measured through objective tests (e.g. grip strength). Fatigue has deleterious effects on HRQL and one's ability to be physically active and socially engaged but does not always correlate with CLD severity. Treatments for HCV and MASLD can improve levels of fatigue and HRQL, but current treatments for PBC do not seem to affect levels of fatigue. We conclude that obtaining PRO data to include HRQL and fatigue are essential for determining the comprehensive burden of CLD and its potential treatments. IMPACT AND IMPLICATIONS: Fatigue is a complex phenomenon associated with both a peripheral cause (neuromuscular failure and sub-maximal cardiorespiratory function) and a central cause (central nervous system dysfunction). Although fatigue is common among patients with CLD, it does not always correlate with the severity of the liver disease, but fatigue is related with significant decreases in patients' health related quality of life (HRQL). Appreciating the impact of fatigue using validated self-report measurements is important to better understand the burden of CLD and the effectiveness of treatment.

Abstract
Fatigue is considered one of the most frequent and debilitating symptoms in primary biliary cholangitis (PBC), affecting over 50% of PBC patients. One in five patients with PBC suffer from severe fatigue, which significantly impairs quality of life. Fatigue is made up of a central and a peripheral component, whose pathophysiology is still greatly unresolved. Central fatigue is characterised by a lack of self-motivation and can manifest both in physical and mental activities (lack of intention). Peripheral fatigue includes neuromuscular dysfunction and muscle weakness (lack of ability). Peripheral fatigue could be explained by an excessive deviation from aerobic to anaerobic metabolism leading to excessive lactic acid accumulation and therefore accelerated decline in muscle function and prolonged recovery time. As opposed to itching, and with the exception of end-stage liver disease, fatigue is not related to disease progression. The objective of this review is to outline current understanding regarding the pathophysiology of fatigue, the role of comorbidities and contributing factors, the main tools for fatigue assessment, the failed therapeutic options, and future treatment perspectives for this disabling symptom. Since fatigue is an extremely common and debilitating symptom and there is still no licensed therapy for fatigue in PBC patients, further research is warranted to understand its causative mechanisms and to find an effective treatment.

Abstract
PURPOSE OF REVIEW This review analyses the main features of primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC) and provides an overview of the currently available (bile acid) bile acid related treatments. RECENT FINDINGS In PBC, biliary injury is the consequence of a dysregulated intrahepatic and systemic immune response. Given the close association between PSC and inflammatory bowel disease (IBD), the microbiota represents an important factor in the development of PSC. Bile acid based pharmacological treatments could represent promising therapeutic strategies in the management of cholangiopathies. SUMMARY Cholangiopathies include a spectrum of diseases resulting in cholestasis, an impairment of bile flow in the biliary tree, leading to biliary obstruction and damage as well as liver inflammation and fibrosis. PSC and PBC are highly heterogeneous cholangiopathies and progressive disorders with defined pathophysiological mechanisms. Curative treatments have not been established, and although their prevalence is low, they are a frequent indication for liver transplantation in the advanced stages of cholangiopathies. These diseases still present with unmet therapeutic strategies, also taking into account that on average 30-40% of patients undergoing liver transplantation will have recurrence of the original illness.

Abstract
Chronic liver disease (CLD) is one of the leading causes of disability-adjusted life years in many countries. A recent understanding of nuclear bile acid receptor pathways has increased focus on the impact of crosstalk between the gut, bile acids, and liver on liver pathology. While conventionally used in cholestatic disorders and to dissolve gallstones, the discovery of bile acids' influence on the gut microbiome and human metabolism offers a unique potential for their utility in early and advanced liver diseases because of diverse etiologies. Based on these findings, preclinical studies using bile acid-based molecules have shown encouraging results at addressing liver inflammation and fibrosis. Emerging data also suggest that bile acid profiles change distinctively across various causes of liver disease. We summarize the current knowledge and evidence related to bile acids in health and disease and discuss culminated and ongoing therapeutic trials of bile acid derivatives in CLD. In the near future, further evidence in this area might help clinicians better detect and manage liver diseases.

Abstract
The human abdomen harbors organs that the host's immune system can attack easily. This immunological storm front leads to diseases like Crohn's Disease, Ulcerative Colitis or Autoimmune Hepatitis. Serious symptoms like pain, diarrhea, fatigue, or malnutrition accompany these diseases. Moreover, many patients have an increased risk for developing special kind of malignancies and some autoimmune disease can show a high mortality. The key to treat them consists of a deep understanding of their pathophysiology. In vitro and especially in vivo basic research laid the foundation for our increasing knowledge about it during the past years. This enabled the development of new therapeutic approaches that interact directly with cytokines or immune cells instead of building the treatment on a total immunosuppression. Different kind of antibodies, kinase inhibitors, and regulatory T cells build the base for these approaches. This review shows new therapeutical approaches in gastrointestinal autoimmune diseases in context to their pathophysiological basis.

Abstract
BACKGROUND AND AIMS To assess the characteristics, care, treatment response, and outcomes of primary biliary cholangitis (PBC) patients recently followed-up by hepato-gastroenterologists in various French and Belgian healthcare settings. METHODS This retrospective cohort study included patients with PBC who recently visited 79 hepato-gastroenterologists in France and Belgium. Data were collected at the time of diagnosis and at last visit and were compared according to biochemical response (BR) to ursodeoxycholic acid (UDCA) (BR), using Paris I-II criteria, and clinical outcomes. RESULTS A total of 436 patients (mean age at diagnosis 57 years, 88% females, median follow-up 5.2 years) were included. Liver biopsy, transient elastography, or none of these two procedures were performed at baseline in 216 (50%), 194 (45%), and 107 (25%) patients, respectively. Late-stage disease (histological stage III or IV, or transient elastography ≥9.6 kPa, or bilirubin >17 µM and albumin <35 g/L, or platelets <150.000/µl, or unequivocal signs of portal hypertension or cirrhosis) was reported in 37% of patients. UDCA was taken by 95% of patients (27% had suboptimal dosage). Inadequate BR was observed in 37% of patients. Clinicians overestimated disease control. Liver-related complications occurred in 9% of patients. Bilirubin and albumin independently predicted inadequate BR; advanced disease stage and inadequate BR independently predicted complications. CONCLUSIONS Recently followed-up French and Belgian patients with PBC had homogeneous management. Late stage at diagnosis and inadequate BR were reported in around 40% of patients. Disease control was frequently overestimated by clinicians. Disease stage and BR were the main prognostic factors.

Abstract
Primary biliary cholangitis is a chronic condition characterised by autoimmune destruction of intralobular bile ducts. Publications have shown widespread gaps in the care of patients with primary biliary cholangitis. This article reviews the literature regarding currently licensed first- and second-line therapies and evaluates therapeutic options for symptomatic management of primary biliary cholangitis. Ursodeoxycholic acid is recommended for all patients with primary biliary cholangitis, with obeticholic acid available as second-line therapy, both having demonstrated safety and efficacy. Potential disease-modifying therapies, such as fibrates and budesonide, require further investigation before licensing. Cholestyramine is first-line therapy for pruritus, albeit with limited evidence and common side-effects. There is no licensed therapy for primary biliary cholangitis-related fatigue; treating underlying causes where applicable is recommended. Disease-modifying and symptomatic therapies must be considered in tandem when managing patients with primary biliary cholangitis. Emerging therapies show initial promise but further randomised trials with long-term follow up are required to evaluate their efficacy as single or combination therapies.

Abstract
Primary biliary cholangitis (PBC) is an immune-mediated chronic liver disease characterized by biliary epithelial injury, cholestasis, and progressive fibrosis that can lead to cirrhosis and requirement for liver transplantation. All patients with PBC should receive initial treatment with ursodeoxycholic acid (UDCA), and odds for response are based on characteristics at baseline. It is important to have clear definitions of patients at risk for a poor response to therapy, of biochemical markers of an incomplete response, and standardized management. Patients typically are assessed after 12 months of treatment with UDCA for biochemical markers of response. However, evaluation at 6 months has been proposed for patients with more severe disease or symptoms (such as pruritus or fatigue). Markers of response to therapy include reduced serum levels of alkaline phosphatase and bilirubin (Paris-2, Toronto, GLOBE, and so forth); patients with high levels of total and conjugated bilirubin or levels of alkaline phosphatase more than 1.5-fold the upper limit of normal should be considered for second-line therapy. Patients with adequate biochemical responses can continue UDCA monotherapy. Incomplete responders should be considered for second-line therapies with obeticholic acid (licensed) or fibrates (unlicensed) in addition to continued treatment with UDCA. Patients with PBC should be followed up for life.

Abstract
Cholestatic liver disease is a disease that causes liver damage and fibrosis owing to bile stasis. It is represented by primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC), but the pathophysiological pathways that cause bile stasis in both diseases are different. The pathogenesis of the disease is still unclear, although autoimmune mechanisms have been postulated and partially elucidated. Although the disease may progress slowly with only mild liver dysfunction, it may progress to liver cirrhosis or liver failure, which require liver transplantation. As a medical treatment, ursodeoxycholic acid is widely used for PBC and has proved to be very effective against disease progression in cases of PBC. On the other hand, its efficacy is limited in cases of PSC, and the research and development of various drugs are underway. Furthermore, the clinical course of both diseases is quite variable, making the design of clinical trials fairly difficult. In this review, we present the general natural history of PBC and PSC, and provide information on the latest drug therapies currently available and those that are under investigation.

Combination of fibrates with obeticholic acid is able to normalise biochemical liver tests in patients with difficult-to-treat primary biliary cholangitis. Aliment Pharmacol Ther 2021; 53:1138-1146. [PMID: 33764590 DOI: 10.1111/apt.16336] [Citation(s) in RCA: 28] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/24/2020] [Revised: 01/16/2021] [Accepted: 03/01/2021] [Indexed: 02/06/2023]
Abstract
BACKGROUND Obeticholic acid (OCA) and fibrates are second-line therapies for patients with primary biliary cholangitis (PBC) with an inadequate response to ursodeoxycholic acid (UDCA). AIM To know whether OCA and fibrates, administered together in combination with UDCA, have additive beneficial effects in patients with difficult-to-treat PBC. METHODS PBC patients treated for ≥3 months with UDCA, OCA and fibrates (bezafibrate or fenofibrate) due to failure of either second-line therapy were included in a multicentre, uncontrolled retrospective cohort study. Changes in biochemical liver tests and pruritus were analysed using a generalised linear mixed-effect model. RESULTS Among 58 patients included, half received OCA as second-line and fibrates as third-line therapy (Group OCA-Fibrate), while the other half had the inverse therapeutic sequence (Group Fibrate-OCA). The mean duration of triple therapy was 11 months (range 3-26). Compared to dual therapy, triple therapy was associated with a significant gain in alkaline phosphatase (ALP) reduction: 22% per first year (95% CI 12%-31%), an effect that was stronger in OCA-Fibrate than in Fibrate-OCA group. Triple therapy was associated with a 3.4 (95% CI 1.4-8.2) odds ratio (OR) of reaching normal ALP and with a significant decrease in gamma-glutamyl transpeptidase (GGT), alanine aminotransferase (ALT), aspartate aminotransferase (AST) and total bilirubin. The ORs of achieving the Paris-2 and Toronto criteria of adequate biochemical response were 6.8 (95% CI 2.8-16.7) and 9.2 (95% CI 3.4-25.1) respectively. Finally, triple therapy significantly improved pruritus in OCA-Fibrate but not in Fibrate-OCA group. CONCLUSIONS Triple therapy with UDCA, OCA and fibrates is able to normalise biochemical liver tests and improve pruritus in patients with difficult-to-treat PBC.

Can J Gastroenterol Hepatol 2021; 2021:6691425. [PMID: 33542908 PMCID: PMC7843178 DOI: 10.1155/2021/6691425] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/05/2020] [Revised: 01/13/2021] [Accepted: 01/15/2021] [Indexed: 02/05/2023] Open
Abstract
Aim To compare the response between the current recommended dosage 13-15 mg/kg/d and 20 mg/kg/d dose of ursodeoxycholic acid (UDCA) in primary biliary cholangitis (PBC) patients who do not respond completely to a standard dose of UDCA. Methods We included 73 patients with poor response and randomized them into two groups to investigate whether increasing the dosage of UDCA was beneficial to nonresponders. Patients assigned to the 13-15 mg/kg/d group continued with standard therapy, and participants in the 18-22 mg/kg/d group switched to the higher dosage (18-22 mg/kg/d), with a follow-up of 12 months for both groups. The primary endpoints were the rate of response at 6 months and drug side effects. Results According to the Paris 2 criteria, patients receiving 18-22 mg/kg/d UDCA achieved a response rate of 59.4% compared with 36.1% in the standard dosage group (P=0.046) at 6 months, respectively. At 12 months, the high-UDCA-dosage group achieved a response rate of 59.4% compared with 47.2% in the standard dosage group (P=0.295), respectively. Additionally, the risk score predicted by the UK-PBC model was lower in high-dosage UDCA-treated patients than in the standard dosage group (all P < 0.05). Side effects include diarrhea, nausea and vomiting, rash, and newly developed high blood pressure, which were mild and tolerated. Conclusions Patients treated with the high UDCA dosage showed some advantages over those who continued the standard dosage in terms of biochemical remission and disease progression, indicating that standard therapy with UDCA for 6 months and then another 1 year with high UDCA dosage for nonresponders could be a treatment option before second-line therapy is recommended.

Abstract
Primary sclerosing cholangitis (PSC) and primary biliary cirrhosis (PBC) are slow progressive diseases which have been increasing in prevalence. The pathogeneses of PBC and PSC are incompletely understood but the underlying mechanisms appear to be fundamentally autoimmune in origin. Although PBC and PSC appear to be separate entities, overlap has been described. Diagnosis depends on a combination of serological markers, imaging, and pathological criteria. The mainstay of treatment has been ursodeoxycholic acid and in some cases of extrahepatic biliary obstruction and overlap disorder, endoscopic retrograde cholangiopancreatography has been useful.

Abstract
Primary biliary cholangitis (PBC) is a rare autoimmune cholestatic liver disease that may progress to fibrosis or cirrhosis. Treatment options are currently limited. Ursodeoxycholic acid (UDCA) remains first-line therapy and has been proven to normalize serum biochemistries, halt histologic disease progression, and lead to patient survival comparable to the general population. Obeticholic acid (OCA) was recently approved as adjunct therapy in PBC patients with inadequate response or intolerance to UDCA. However, OCA has been associated with worsening pruritus in clinical studies which may limit its use in this patient population. Several studies are currently underway to address the lack of treatment options for PBC. Of these, fibrates, which have been used in Japan for over a decade, have produced promising results. Furthermore, as currently approved therapies for PBC do not address the potentially debilitating clinical symptoms of PBC such as pruritus and fatigue, supplemental therapy is often required for symptom control.

Abstract
BACKGROUND Improved knowledge of the molecular pathophysiology and immunopathogenesis of cholestatic liver diseases in recent years has led to an increased interest in developing novel therapies. Patients with cholestatic liver disease often require different approaches to assessment and management of suspected drug-induced liver injury (DILI) compared to those with healthy livers and those with parenchymal liver diseases. At present, there are no regulatory guidelines or society position papers, that systematically address best practices pertaining to detection of DILI in these patients. AIMS To outline best practices for detection, assessment and management of suspected acute DILI during clinical trials in adults with the cholestatic liver diseases - Primary Biliary Cholangitis (PBC) and Primary Sclerosing Cholangitis (PSC). METHODS This is one of the several papers developed by the IQ DILI Initiative, which is comprised of members from 16 pharmaceutical companies, in collaboration with DILI experts from academia and regulatory agencies. The contents are the result of an extensive literature review, as well as in-depth discussions among industry, regulatory and academic DILI experts, to achieve consensus recommendations on DILI-related issues occurring during clinical trials for cholestatic liver diseases. RESULTS Recommended best practices are outlined pertaining to hepatic eligibility criteria, monitoring of liver tests, approach to a suspected DILI signal, and hepatic discontinuation rules. CONCLUSIONS This paper provides a framework for the approach to detection, assessment and management of suspected acute DILI occurring during clinical trials in adults with cholestatic liver disease.

Abstract
Primary biliary cholangitis is an uncommon cholestatic liver disease predominantly affecting middle-aged women. Left untreated, there is a high risk of progression to end-stage liver disease. Few treatment options exist. To date, ursodeoxycholic acid (UDCA) and obeticholic acid (OCA) are the only medical therapies approved for use, other than symptomatic treatments and liver transplantation, the latter of which is reserved for those developing complications of cirrhosis or with intractable pruritus. UDCA improves outcomes, but many patients do not adequately respond. OCA therapy may improve response, but long-term data are limited. New therapies are desperately needed, but evaluation has been limited by the fact that the disease is heterogeneous, hard end points take years to develop, and there are different criteria in use for determining therapeutic response based on surrogate biomarkers. Fibrates appear to be the most promising new therapy and have beneficially affected surrogate end points and are beginning to show improvement in clinical end points.

Abstract
BACKGROUND & AIMS There is no proven treatment for ursodeoxycholic acid (UDCA)-refractory primary biliary cholangitis (PBC) other than obeticholic acid. Although fibrates have been reported to improve biochemical parameters, the long-term effects remain unclear. This study evaluated the effect of fibrate on clinical outcomes of UDCA-refractory PBC. METHODS Patients whose alkaline phosphatase (ALP) was not normalized with at least 13 mg/kg of UDCA treatment for >1 year were included from two tertiary referral centres. The primary outcome was ALP normalization. Secondary outcomes included the development of cirrhosis and hepatic deterioration. Immortal time bias was adjusted using the Mantel-Byar method. RESULTS A total of 100 UDCA-refractory PBC patients were included: 71 patients received UDCA alone (the UDCA group) and 29 patients received UDCA plus additional fibrate treatment of 160 mg/d fenofibrate or 400 mg/d bezafibrate (the fibrate/UDCA group). During the follow-up period, the probability of ALP normalization was significantly higher in the fibrate/UDCA group (hazard ratio [HR] = 5.00, 95% confidence interval = 2.87-8.27, P < 0.001). Among 58 non-cirrhotic patients (43 in the UDCA group and 15 in the fibrate/UDCA group), 19 patients (44.1%) in the UDCA group and none in the fibrate/UDCA group developed cirrhosis (HR = 0.12, P = 0.04). Hepatic deterioration (Child-Pugh score increase or signs of decompensated cirrhosis) occurred in 17 patients (23.9%) of the UDCA group and none in the fibrate/UDCA group in which the difference was significant (HR = 0.12, P = 0.04). CONCLUSIONS In patients with UDCA-refractory PBC, additional fibrate treatment is associated with a higher probability of ALP normalization and a lower risk of cirrhosis development and hepatic deterioration.

Abstract
Primary biliary cholangitis is a chronic liver disorder characterized by progressive cholestasis that may evolve to liver cirrhosis. While ursodeoxycholic acid is the treatment of choice, around 30% of patients do not respond to this therapy. These patients have a poorer prognosis, hence should be identified early in order to be offered therapy options. Along these lines, improved understanding of the condition's pathophysiology has allowed the development of newer drugs, including obeticholic acid and fibrates. This review offers a perspective on risk stratification and treatment for these patients, from ursodeoxycholic acid to second-line treatments.

Abstract
The main objective of this study was to investigate the potential protective effect of ursodeoxycholic acid (UDCA) on fructose/streptozotocin-induced diabetic cataract in rats. The diabetic model (DM) was induced through the administration of 10% fructose in drinking water for 2 weeks followed by streptozotocin injection (intraperitoneal). One week later, hyperglycemia was assisted and diabetic animals were treated with UDCA either as local eye drops (0.5% solution, four times/day) or orally (100 mg/kg b.w.). Cataract formation was monitored biweekly and scored into four stages. After 12 weeks of treatment, rats were subjected to ophthalmological examination, and then, their blood and lenses were prepared for biochemical analysis of glucose, insulin, reduced glutathione, total antioxidant capacity, malondialdehyde, hydrogen peroxide, caspase-12, and lenticular total proteins. In addition, tertiary structure and conformational changes of lenticular soluble proteins were analyzed using SDS-PAGE and UV absorption while changes in lenticular α-crystallin structure were investigated using intrinsic tryptophan fluorescence. Results demonstrated that both local and oral UDCA restored the normal levels of lens T-AOC, MDA, H2 O2 , and caspase-12 and improved noticeably the levels of the lens GSH and total proteins. In addition, conformational and tertiary structure changes of soluble lens proteins were significantly reduced in UDCA-treated groups. Morphological examination of lenses revealed decreased score of cataract progression in UDCA-treated groups compared to DM animals. It was concluded that UDCA decreased the incidence of diabetic cataract by maintaining the antioxidant status, reducing the endoplasmic reticulum stress, and suppressing the structural changes of soluble lens proteins.

Abstract
Clinical outcome for patients with primary biliary cholangitis (PBC) is dictated by development of cirrhosis, portal hypertension and its associated complications; including for some, a predisposition toward hepatocellular carcinoma. However rates of clinical progression vary, and accurately identifying disease course is of critical importance to patients, clinicians, as well as industry, who are committed to developing new effective and life-prolonging therapy as well as treating symptoms that appear disproportionate to underlying disease severity. Patients seek reassurance and guidance as to their own prognosis, and clinicians wish to confidently recognise those at highest risk of poor outcomes as equally as they strive to reassure individuals with a more favourable disease trajectory. International registries have facilitated a much greater knowledge of disease incidence and heterogeneity of presenting phenotypes. In so doing they highlight the opportunity to provide a more individualized estimate of the clinical course that patients experience, and have led to a renewed approach to risk stratification; both in terms of 'hard outcomes' and also disease-associated complications in PBC specifically.

Abstract
UNLABELLED Changes over time in the presenting features and clinical course of patients with primary biliary cholangitis are poorly described. We sought to describe temporal trends in patient and disease characteristics over a 44-year period across a large international primary biliary cholangitis cohort of 4,805 patients diagnosed between 1970 and 2014, from 17 centers across Europe and North America. Patients were divided into five cohorts according to their year of diagnosis: 1970-1979 (n = 143), 1980-1989 (n = 858), 1990-1999 (n = 1,754), 2000-2009 (n = 1,815), and ≥2010 (n = 235). Age at diagnosis, disease stage, response to ursodeoxycholic acid, and clinical outcomes were compared. Mean age at diagnosis increased incrementally by 2-3 years per decade from 46.9 ± 10.1 years in the 1970s to 57.0 ± 12.1 years from 2010 onward (P < 0.001). The female to male ratio (9:1) and antimitochondrial antibody positivity (90%) were not significantly variable. The proportion of patients presenting with mild biochemical disease (according to Rotterdam staging) increased from 41.3% in the 1970s to 72.2% in the 1990s (P < 0.001) and remained relatively stable thereafter. Patients with a mild histological stage at diagnosis increased from 60.4% (1970-1989) to 76.5% (1990-2014) (P < 0.001). Correspondingly, response to ursodeoxycholic acid according to Paris-I criteria increased; 51.7% in the 1970s and 70.5% in the 1990s (P < 0.001). Recent decades were also characterized by lower decompensation rates (18.5% in the 1970s to 5.8% in the 2000s, P < 0.001) and higher 10-year transplant-free survival (48.4%, 68.7%, 79.7%, and 80.1% for each respective cohort; P < 0.001). CONCLUSION In recent decades, a pattern of primary biliary cholangitis presentation consistent with an older age at diagnosis alongside reduced disease severity has been noted; the observed trends may be explained by an increase in routine testing of liver function and/or a changing environmental trigger.

Abstract
UNLABELLED Obeticholic acid (OCA), a potent farnesoid X receptor agonist, was studied as monotherapy in an international, randomized, double-blind, placebo-controlled phase 2 study in patients with primary biliary cholangitis who were then followed for up to 6 years. The goals of the study were to assess the benefit of OCA in the absence of ursodeoxycholic acid, which is relevant for patients who are intolerant of ursodeoxycholic acid and at higher risk of disease progression. Patients were randomized and dosed with placebo (n = 23), OCA 10 mg (n = 20), or OCA 50 mg (n = 16) given as monotherapy once daily for 3 months (1 randomized patient withdrew prior to dosing). The primary endpoint was the percent change in alkaline phosphatase from baseline to the end of the double-blind phase of the study. Secondary and exploratory endpoints included change from baseline to month 3/early termination in markers of cholestasis, hepatocellular injury, and farnesoid X receptor activation. Efficacy and safety continue to be monitored through an ongoing 6-year open-label extension (N = 28). Alkaline phosphatase was reduced in both OCA groups (median% [Q1, Q3], OCA 10 mg -53.9% [-62.5, -29.3], OCA 50 mg -37.2% [-54.8, -24.6]) compared to placebo (-0.8% [-6.4, 8.7]; P < 0.0001) at the end of the study, with similar reductions observed through 6 years of open-label extension treatment. OCA improved many secondary and exploratory endpoints (including γ-glutamyl transpeptidase, alanine aminotransferase, conjugated bilirubin, and immunoglobulin M). Pruritus was the most common adverse event; 15% (OCA 10 mg) and 38% (OCA 50 mg) discontinued due to pruritus. CONCLUSION OCA monotherapy significantly improved alkaline phosphatase and other biochemical markers predictive of improved long-term clinical outcomes. Pruritus increased dose-dependently with OCA treatment. Biochemical improvements were observed through 6 years of open-label extension treatment. (Hepatology 2018;67:1890-1902).

Abstract
Primary biliary cholangitis (PBC) is an autoimmune liver disease characterized by chronic granulomatous lymphocytic cholangitis of the small bile ducts. PBC was a leading indication for liver transplant in the United States; with early diagnosis and treatment, the majority of patients with PBC have a normal life expectancy. Pathogenesis involves inflammatory damage of bile duct epithelium secondary to innate and adaptive immune responses, and toxicity from accumulated bile acids. Cholestasis and disease progression can lead to cirrhosis. Extrahepatic complications include dyslipidemia, metabolic bone disease, and fat-soluble vitamin deficiency. Ursodeoxycholic acid is a well-established therapy. Novel targeted therapeutics are being developed.

Abstract
Primary biliary cholangitis (PBC) is a chronic autoimmune cholestatic liver disease that predominantly affects women in early to middle age. It is typically associated with autoantibodies to mitochondrial antigens and results in immune-mediated destruction of small and medium-sized intrahepatic bile ducts leading to cholestasis, hepatic fibrosis and may progress to cirrhosis or hepatic failure and, in some cases, hepatocellular carcinoma. The clinical presentation and the natural history of PBC have improved over the years due to recognition of earlier widespread use of ursodeoxycholic acid (UDCA); about one-third of patients show suboptimal biochemical response to UDCA with poor prognosis. Until recently, UDCA was the only US Food and Drug Administration approved agent for this disease for more than two decades; obeticholic acid was approved in 2016 for treatment of patients with PBC with a suboptimal response or intolerance to UDCA. Currently, liver transplantation is the most effective treatment modality for PBC patients with end-stage liver disease. This review will focus on the recent advances in therapy of primary biliary cholangitis, with emphasis on obeticholic acid.

Abstract
Primary sclerosing cholangitis (PSC) and primary biliary cholangitis (PBC) are the most common cholestatic liver diseases (CLD) in adults. Liver transplant (LT) is desirable for those who progress to end-stage liver disease. CLD have become an uncommon indication for LT. PSC and PBC accounted for 7.1% of all adult LT in 2015. CLD have the best post-LT outcomes compared with other indications for LT. Disease recurrence of PSC and PBC after LT is reported in up to 37% and 43% of LT recipients, respectively. Although recurrent PBC does not affect post-LT outcomes, recurrent PSC is associated with worse post-LT survival.

Abstract
The most common causes of chronic cholestatic liver disease are primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC). Both disease processes are characterized by a destruction of intrahepatic and/or extrahepatic biliary ducts. The etiology is not entirely clear; however, there is an underlying autoimmune component contributing to both disease processes. Although PBC and PSC are often diagnosed and managed in the outpatient setting, in some instances, a patient may have jaundice, fatigue, and pruritus requiring evaluation and determination of the cholestatic cause. Patients with PSC should be monitored for evidence of cholangiocarcinoma, colon cancer, and gallbladder polyps as they are at an increased risk of malignant neoplasms. Liver transplant has the potential for improving quality of life, although disease recurrence is a risk.

Abstract
BACKGROUND Primary biliary cholangitis (previously primary biliary cirrhosis) is a chronic liver disease caused by the destruction of small intra-hepatic bile ducts resulting in stasis of bile (cholestasis), liver fibrosis, and liver cirrhosis. The optimal pharmacological treatment of primary biliary cholangitis remains uncertain. OBJECTIVES To assess the comparative benefits and harms of different pharmacological interventions in the treatment of primary biliary cholangitis through a network meta-analysis and to generate rankings of the available pharmacological interventions according to their safety and efficacy. However, it was not possible to assess whether the potential effect modifiers were similar across different comparisons. Therefore, we did not perform the network meta-analysis, and instead, assessed the comparative benefits and harms of different interventions using standard Cochrane methodology. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 2), MEDLINE, Embase, Science Citation Index Expanded, World Health Organization International Clinical Trials Registry Platform, and randomised controlled trials registers to February 2017 to identify randomised clinical trials on pharmacological interventions for primary biliary cholangitis. SELECTION CRITERIA We included only randomised clinical trials (irrespective of language, blinding, or publication status) in participants with primary biliary cholangitis. We excluded trials which included participants who had previously undergone liver transplantation. We considered any of the various pharmacological interventions compared with each other or with placebo or no intervention. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. We calculated the odds ratio (OR) and rate ratio with 95% confidence intervals (CI) using both fixed-effect and random-effects models based on available-participant analysis with Review Manager 5. We assessed risk of bias according to Cochrane, controlled risk of random errors with Trial Sequential Analysis, and assessed the quality of the evidence using GRADE. MAIN RESULTS We identified 74 trials including 5902 participants that met the inclusion criteria of this review. A total of 46 trials (4274 participants) provided information for one or more outcomes. All the trials were at high risk of bias in one or more domains. Overall, all the evidence was low or very low quality. The proportion of participants with symptoms varied from 19.9% to 100% in the trials that reported this information. The proportion of participants who were antimitochondrial antibody (AMA) positive ranged from 80.8% to 100% in the trials that reported this information. It appeared that most trials included participants who had not received previous treatments or included participants regardless of the previous treatments received. The follow-up in the trials ranged from 1 to 96 months.The proportion of people with mortality (maximal follow-up) was higher in the methotrexate group versus the no intervention group (OR 8.83, 95% CI 1.01 to 76.96; 60 participants; 1 trial; low quality evidence). The proportion of people with mortality (maximal follow-up) was lower in the azathioprine group versus the no intervention group (OR 0.56, 95% CI 0.32 to 0.98; 224 participants; 2 trials; I2 = 0%; low quality evidence). However, it has to be noted that a large proportion of participants (25%) was excluded from the trial that contributed most participants to this analysis and the results were not reliable. There was no evidence of a difference in any of the remaining comparisons. The proportion of people with serious adverse events was higher in the D-penicillamine versus no intervention group (OR 28.77, 95% CI 1.57 to 526.67; 52 participants; 1 trial; low quality evidence). The proportion of people with serious adverse events was higher in the obeticholic acid plus ursodeoxycholic acid (UDCA) group versus the UDCA group (OR 3.58, 95% CI 1.02 to 12.51; 216 participants; 1 trial; low quality evidence). There was no evidence of a difference in any of the remaining comparisons for serious adverse events (proportion) or serious adverse events (number of events). None of the trials reported health-related quality of life at any time point. FUNDING nine trials had no special funding or were funded by hospital or charities; 31 trials were funded by pharmaceutical companies; and 34 trials provided no information on source of funding. AUTHORS' CONCLUSIONS Based on very low quality evidence, there is currently no evidence that any intervention is beneficial for primary biliary cholangitis. However, the follow-up periods in the trials were short and there is significant uncertainty in this issue. Further well-designed randomised clinical trials are necessary. Future randomised clinical trials ought to be adequately powered; performed in people who are generally seen in the clinic rather than in highly selected participants; employ blinding; avoid post-randomisation dropouts or planned cross-overs; should have sufficient follow-up period (e.g. five or 10 years or more); and use clinically important outcomes such as mortality, health-related quality of life, cirrhosis, decompensated cirrhosis, and liver transplantation. Alternatively, very large groups of participants should be randomised to facilitate shorter trial duration.

Abstract
Primary biliary cholangitis (PBC) is an immunological condition that causes a significant health disturbance and dramatically reduces the quality of life for those affected with the disease. It is a potentially fatal disease that can lead to multiple hepatic and extrahepatic complications. Having adequate therapeutic interventions that can improve the course of the disease is imperative in reducing the associated morbidity and mortality. Ursodeoxycholic acid (UDCA) is the gold standard therapy. However, it has been associated with suboptimal response rates in a significant proportion of patients. Despite UDCA, approximately 35%-40% of individuals with PBC still experience a progression of the disease, leading to liver failure and requiring liver transplantation. Recent studies of new pharmacological approaches have shown beneficial outcomes. Some of these agents can now be applied to a clinical scenario. In this review article, we will outline the new and emerging treatments for PBC.

Abstract
Primary biliary cholangitis (PBC, primary biliary cirrhosis) is an autoimmune cholestatic liver disease characterized by chronic nonsuppurative destructive cholangitis and the presence of serum antimitochondrial antibodies. Ursodeoxycholic acid is the only drug approved by the US Food and Drug Administration to treat PBC. However, one-third of patients show incomplete responses to ursodeoxycholic acid and a poor prognosis. A number of old and new medications have been used in these patients, such as fibrates, glucocorticoids, immunosuppressants, obeticholic acid, mesenchymal stem cells, biological agents (anti-interleukin-12, cytotoxic T-lymphocyte antigen 4 immunoglobulin, anti-CD20), and antifibrotic drugs. This article reviews the therapeutic advances of these old and new medications in patients with PBC.

Abstract
All patients with primary biliary cirrhosis (PBC) and abnormal liver biochemistry should be considered for specific therapy. Ursodeoxycholic acid (UDCA) is the only FDA-approved drug for treating PBC. Approximately 40% of patients with PBC respond incompletely to treatment with UDCA, thus having increased risk of death or need for liver transplantation. No second-line therapies for patients with inadequate response to UDCA therapy have been approved. This review provides a current perspective on potential new approaches to treatment in PBC, and highlights some of the challenges we face in evaluating and effectively implementing those treatments.

Abstract
BACKGROUND & AIMS Polycystic liver diseases (PLDs) are genetic disorders characterized by progressive biliary cystogenesis. Current therapies show short-term and/or modest beneficial effects. Cystic cholangiocytes hyperproliferate as a consequence of diminished intracellular calcium levels ([Ca(2+)]i). Here, the therapeutic value of ursodeoxycholic acid (UDCA) was investigated. METHODS Effect of UDCA was examined in vitro and in polycystic (PCK) rats. Hepatic cystogenesis and fibrosis, and the bile acid (BA) content were evaluated from the liver, bile, serum, and kidneys by HPLC-MS/MS. RESULTS Chronic treatment of PCK rats with UDCA inhibits hepatic cystogenesis and fibrosis, and improves their motor behaviour. As compared to wild-type animals, PCK rats show increased BA concentration ([BA]) in liver, similar hepatic Cyp7a1 mRNA levels, and diminished [BA] in bile. Likewise, [BA] is increased in cystic fluid of PLD patients compared to their matched serum levels. In PCK rats, UDCA decreases the intrahepatic accumulation of cytotoxic BA, normalizes their diminished [BA] in bile, increases the BA secretion in bile and diminishes the increased [BA] in kidneys. In vitro, UDCA inhibits the hyperproliferation of polycystic human cholangiocytes via a PI3K/AKT/MEK/ERK1/2-dependent mechanism without affecting apoptosis. Finally, the presence of glycodeoxycholic acid promotes the proliferation of polycystic human cholangiocytes, which is inhibited by both UDCA and tauro-UDCA. CONCLUSIONS UDCA was able to halt the liver disease of a rat model of PLD through inhibiting cystic cholangiocyte hyperproliferation and decreasing the levels of cytotoxic BA species in the liver, which suggests the use of UDCA as a potential therapeutic tool for PLD patients.

Efficacy of obeticholic acid in patients with primary biliary cirrhosis and inadequate response to ursodeoxycholic acid. Gastroenterology 2015; 148:751-61.e8. [PMID: 25500425 DOI: 10.1053/j.gastro.2014.12.005] [Citation(s) in RCA: 387] [Impact Index Per Article: 43.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2014] [Revised: 12/05/2014] [Accepted: 12/08/2014] [Indexed: 02/08/2023]
Abstract
BACKGROUND & AIMS We evaluated the efficacy and safety of obeticholic acid (OCA, α-ethylchenodeoxycholic acid) in a randomized controlled trial of patients with primary biliary cirrhosis who had an inadequate response to ursodeoxycholic acid therapy. METHODS We performed a double-blind study of 165 patients with primary biliary cirrhosis (95% women) and levels of alkaline phosphatase (ALP) 1.5- to 10-fold the upper limit of normal. Patients were randomly assigned to groups given 10 mg, 25 mg, or 50 mg doses of OCA or placebo, once daily for 3 months. Patients maintained their existing dose of ursodeoxycholic acid throughout the study. The primary outcome was change in level of ALP from baseline (day 0) until the end of the study (day 85 or early termination). We also performed an open-label extension of the trial in which 78 patients were enrolled and 61 completed the first year. RESULTS OCA was superior to placebo in achieving the primary end point. Subjects given OCA had statistically significant relative reductions in mean ALP from baseline to the end of the study (P < .0001 all OCA groups vs placebo). Levels of ALP decreased 21%-25% on average from baseline in the OCA groups and 3% in the placebo group. Sixty-nine percent (68 of 99) of patients given OCA had at least a 20% reduction in ALP compared with 8% (3 of 37) of patients given placebo (P < .0003). Among secondary end points, levels of γ-glutamyl transpeptidase decreased 48%-63%, on average, among subjects given OCA, vs a 7% decrease in the group given placebo; levels of alanine aminotransferase decreased 21%-35% on average among subjects given OCA vs none of the patients given placebo. Pruritus was the principal adverse event; incidence values in the OCA 10 mg, 25 mg, and 50 mg groups were 47% (not significantly different), 87% (P < .0003), and 80% (P < .006), respectively, vs 50% in the placebo group. In the extension study, levels of ALP continued to decrease to a mean level of 202 ± 11 U/L after 12 months vs 285 ± 15 U/L at baseline. CONCLUSIONS Daily doses of OCA, ranging from 10 to 50 mg, significantly reduced levels of ALP, γ-glutamyl transpeptidase, and alanine aminotransferase, compared with placebo, in patients with primary biliary cirrhosis who had inadequate responses to ursodeoxycholic acid. The incidence and severity of pruritus were lowest among patients who received 10 mg/d OCA. Biochemical responses to OCA were maintained in a 12-month open-label extension trial.

Abstract
Primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC) are two major types of chronic cholestatic liver disease. Each disorder has distinguishing features and variable progression, but both may ultimately result in cirrhosis and hepatic failure. The following offers a review of PBC and PSC, beginning with a general overview of disease etiology, pathogenesis, diagnosis, clinical features, natural course, and treatment. In addition to commonly associated manifestations of fatigue, pruritus, and fat-soluble vitamin deficiency, select disease-related topics pertaining to women's health are discussed including metabolic bone disease, hyperlipidemia and cardiovascular risk, and pregnancy-related issues influencing maternal disease course and birth outcomes. This comprehensive review of PBC and PSC highlights some unique clinical considerations in the care of female patients with cholestatic liver disease.

Abstract
PURPOSE OF REVIEW Primary biliary cirrhosis (PBC) can lead to end-stage liver disease and death. Ursodeoxycholic acid (UDCA) treatment can normalize serum liver enzymes in PBC, and such UDCA-responsive patients have a similar life expectancy as age and sex-matched controls. Nearly up to 50% of the patients with PBC, depending on sex and age at diagnosis, show an incomplete biochemical response to UDCA and require additional/alternative treatment. The purpose of this review is to critically evaluate the molecular mechanisms and clinical benefit of fibrate treatment in these patients. RECENT FINDINGS Fibrates have anticholestatic, anti-inflammatory, and antifibrotic effects in animal and in-vitro studies. The mechanisms that underlie these effects are complementary, and largely mediated through activation of peroxisome proliferator activated receptors. Fibrate treatment ameliorated liver biochemical tests in UDCA unresponsive patients, either as mono-therapy or in combination with UDCA. These results, however, were obtained in case series and small pilot studies. The results of phase III studies, such as the Bezafibrate in Combination With Ursodeoxycholic Acid in Primary Biliary Cirrhosis (BEZURSO) trial, are currently awaited. SUMMARY A considerable body of observational evidence supports the safety and efficacy of fibrate treatment in PBC patients with an incomplete response to UDCA. These results encourage the evaluation of its effects on liver-related morbidity and mortality in larger clinical trials.

Abstract
Primary biliary cirrhosis (PBC) is a chronic, autoimmune, cholestatic liver disease. It is characterized by slow destruction of small intrahepatic bile ducts, impaired biliary secretion and stasis of toxic endogenous bile acids within the liver with progression to liver fibrosis and cirrhosis. It has an increasing prevalence worldwide. It occurs more commonly in women than men at a ratio of 10:1. In most cases, diagnosis relies on a positive antimitochondrial antibody in the context of chronic cholestasis, without the need for a liver biopsy. Ursodeoxycholic acid improves survival even in patients with advanced liver disease. Certain findings such as fatigue, anti-nuclear antibodies, anti-centromere antibodies and the GP210 antinuclear antibody predict a poor outcome. Up to 40% of patients do not respond satisfactorily to ursodeoxycholic acid therapy and should be considered for adjunctive therapies. Several adjunctive and newer therapies are being tested and some appear promising. We provide a review of PBC with a focus on advances in therapies that may impact the management of PBC in the near future.

Abstract
BACKGROUND Long-term use of ursodeoxycholic acid (UDCA) is the recommended therapy in primary biliary cirrhosis (PBC). The lifetime effectiveness and cost-effectiveness of UDCA in PBC have, however, not been assessed. AIM To estimate the health outcomes and lifetime costs of a Norwegian cohort of PBC patients on UDCA. METHODS Norwegian PBC patients (n = 182) (90% females; mean age 56.3 ± 8.9 years; Mayo risk score 4.38) who were included in a 5-year open-label study of UDCA therapy were subsequently followed up for up to 11.5 years. The lifetime survival was estimated using a Weibull survival model. The survival benefit from UDCA was based on a randomised clinical trial from Canada, comparing the effect of non-UDCA and UDCA. Survival and costs of standard care vs. standard care plus UDCA were simulated in a Markov model with death and liver transplantation as major events, invoking transition of a patient's state in the model. RESULTS The gain in life expectancy for a PBC patient on UDCA compared with standard care was 2.24 years (1.19 years discounted). The lifetime treatment costs were EUR 151,403 and EUR 157,741 (EUR 102,912 and EUR 115,031 discounted) for patients with and without UDCA respectively. A probabilistic sensitivity analysis indicated an 82% probability that UDCA entails both greater life expectancy and lower costs than standard care. CONCLUSIONS The results of this study indicate that UDCA therapy is a dominant strategy as it confers reduced morbidity and mortality, as well as cost savings, compared with standard therapy.

Abstract
Autoimmune liver disease spans three predominant processes, from the interface hepatitis of autoimmune hepatitis to the lymphocytic cholangitis of primary biliary cirrhosis, and finally the obstructive fibrosing sclerotic cholangiopathy of primary sclerosing cholangitis. Although all autoimmune in origin, they differ in their epidemiology, presentation and response to immunosuppressive therapy and bile acid based treatments. With an ongoing better appreciation of disease aetiology and pathogenesis, treatment is set ultimately to become more rational. We provide an overview of current and future therapies for patients with autoimmune liver disease, with an emphasis placed on some of the evidence that drives current practice.

Abstract
BACKGROUND Ursodeoxycholic acid is administered to patients with primary biliary cirrhosis, a chronic progressive inflammatory autoimmune-mediated liver disease with unknown aetiology. Despite its controversial effects, the U.S. Food and Drug Administration has approved its usage for primary biliary cirrhosis. OBJECTIVES To assess the beneficial and harmful effects of ursodeoxycholic acid in patients with primary biliary cirrhosis. SEARCH METHODS We searched for eligible randomised trials in The Cochrane Hepato-Biliary Group Controlled Trials Register, The Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, Science Citation Index Expanded, LILACS, Clinicaltrials.gov, and the WHO International Clinical Trials Registry Platform. The literature search was performed until January 2012. SELECTION CRITERIA Randomised clinical trials assessing the beneficial and harmful effects of ursodeoxycholic acid versus placebo or 'no intervention' in patients with primary biliary cirrhosis. DATA COLLECTION AND ANALYSIS Two authors independently extracted data. Continuous data were analysed using mean difference (MD) and standardised mean difference (SMD). Dichotomous data were analysed using risk ratio (RR). Meta-analyses were conducted using both a random-effects model and a fixed-effect model, with 95% confidence intervals (CI). Random-effects model meta-regression was used to assess the effects of covariates across the trials. Trial sequential analysis was used to assess risk of random errors (play of chance). Risks of bias (systematic error) in the included trials were assessed according to Cochrane methodology bias domains. MAIN RESULTS Sixteen randomised clinical trials with 1447 patients with primary biliary cirrhosis were included. One trial had low risk of bias, and the remaining fifteen had high risk of bias. Fourteen trials compared ursodeoxycholic acid with placebo and two trials compared ursodeoxycholic acid with 'no intervention'. The percentage of patients with advanced primary biliary cirrhosis at baseline varied from 15% to 83%, with a median of 51%. The duration of the trials varied from 3 to 92 months, with a median of 24 months. The results showed no significant difference in effect between ursodeoxycholic acid and placebo or 'no intervention' on all-cause mortality (45/699 (6.4%) versus 46/692 (6.6%); RR 0.97, 95% CI 0.67 to 1.42, I² = 0%; 14 trials); on all-cause mortality or liver transplantation (86/713 (12.1%) versus 89/706 (12.6%); RR 0.96, 95% CI 0.74 to 1.25, I² = 15%; 15 trials); on serious adverse events (94/695 (13.5%) versus 107/687 (15.6%); RR 0.87, 95% CI 0.68 to 1.12, I² = 23%; 14 trials); or on non-serious adverse events (27/643 (4.2%) versus 18/634 (2.8%); RR 1.46, 95% CI 0.83 to 2.56, I² = 0%; 12 trials). The random-effects model meta-regression showed that the risk of bias of the trials, disease severity of patients at entry, ursodeoxycholic acid dosage, and trial duration were not significantly associated with the intervention effects on all-cause mortality, or on all-cause mortality or liver transplantation. Ursodeoxycholic acid did not influence the number of patients with pruritus (168/321 (52.3%) versus 166/309 (53.7%); RR 0.96, 95% CI 0.84 to 1.09, I² = 0%; 6 trials) or with fatigue (170/252 (64.9%) versus 174/244 (71.3%); RR 0.90, 95% CI 0.81 to 1.00, I² = 62%; 4 trials). Two trials reported the number of patients with jaundice and showed a significant effect of ursodeoxycholic acid versus placebo or no intervention in a fixed-effect meta-analysis (5/99 (5.1%) versus 15/99 (15.2%); RR 0.35, 95% CI 0.14 to 0.90, I² = 51%; 2 trials). The result was not supported by the random-effects meta-analysis (RR 0.56, 95% CI 0.06 to 4.95). Portal pressure, varices, bleeding varices, ascites, and hepatic encephalopathy were not significantly affected by ursodeoxycholic acid. Ursodeoxycholic acid significantly decreased serum bilirubin concentration (MD -8.69 µmol/l, 95% CI -13.90 to -3.48, I² = 0%; 881 patients; 9 trials) and activity of serum alkaline phosphatases (MD -257.09 U/L, 95% CI -306.25 to -207.92, I² = 0%; 754 patients, 9 trials) compared with placebo or no intervention. These results were supported by trial sequential analysis. Ursodeoxycholic acid also seemed to improve serum levels of gamma-glutamyltransferase, aminotransferases, total cholesterol, and plasma immunoglobulin M concentration. Ursodeoxycholic acid seemed to have a beneficial effect on worsening of histological stage (random; 66/281 (23.5%) versus 103/270 (38.2%); RR 0.62, 95% CI 0.44 to 0.88, I² = 35%; 7 trials). AUTHORS' CONCLUSIONS This systematic review did not demonstrate any significant benefits of ursodeoxycholic acid on all-cause mortality, all-cause mortality or liver transplantation, pruritus, or fatigue in patients with primary biliary cirrhosis. Ursodeoxycholic acid seemed to have a beneficial effect on liver biochemistry measures and on histological progression compared with the control group. All but one of the included trials had high risk of bias, and there are risks of outcome reporting bias and risks of random errors as well. Randomised trials with low risk of bias and low risks of random errors examining the effects of ursodeoxycholic acid for primary biliary cirrhosis are needed.

Abstract
Primary biliary cirrhosis (PBC) is a chronic inflammatory autoimmune disease that mainly targets the cholangiocytes of the interlobular bile ducts in the liver. It is a rare disease with prevalence of less than one in 2000. Its prevalence in developing countries is increasing presumably because of growth in recognition and knowledge of the disease. PBC is thought to result from a combination of multiple genetic factors and superimposed environmental triggers. The contribution of the genetic predisposition is evidenced by familial clustering. Several risk factors, including exposure to infectious agents and chemical xenobiotics, have been suggested. Common symptoms of the disease are fatigue and pruritus, but most patients are asymptomatic at first presentation. The prognosis of PBC has improved because of early diagnosis and use of ursodeoxycholic acid, the only established medical treatment for this disorder. When administered at adequate doses of 13–15 mg/kg/day, up to two out of three patients with PBC may have a normal life expectancy without additional therapeutic measures. However, some patients do not respond adequately to ursodeoxycholic acid and might need alternative therapeutic approaches.

Abstract
IMPORTANCE OF THE FIELD The cholestatic liver diseases comprise a heterogeneous group of disorders which, left untreated, usually progresses to cirrhosis and liver failure. Most are recognized before the onset of advanced fibrosis, thereby affording an opportunity for disease modifying therapy. AREAS COVERED This review will cover the current pharmacologic management of the most common causes of cholestatic liver disease in adults, including primary biliary cirrhosis, primary biliary cirrhosis-autoimmune hepatitis overlap syndrome, primary sclerosing cholangitis, intrahepatic cholestasis of pregnancy, intestinal failure-associated liver disease, and immunoglobulin G4-associated cholangitis. Pharmacologic management of complications of cholestasis will also be reviewed. EXPERT OPINION Effective therapy for most cholestatic liver disease is lacking. Ursodeoxycholic acid (UDCA) slows the progression of primary biliary cirrhosis but the majority of patients do not have a full response. Even in those with a complete response, UDCA does not cure the disease. There is currently no effective medical therapy for primary sclerosing cholangitis. Symptoms and serum liver biochemistry values in intrahepatic cholestasis of pregnancy are improved with UDCA, but it is not certain if this alters the course of disease. Immunoglobulin G4-associated cholangitis is responsive to steroids but may relapse. The farnesoid X receptor agonists are a promising new class of drugs currently being tested in cholestatic liver disease.

Abstract
The dihydroxylated bile acid ursodeoxycholic acid (UDCA) has now been regarded for 20 years as the standard treatment for primary biliary cirrhosis (PBC), a chronic cholestatic immune-mediated condition marked by progressive destruction of small intrahepatic bile ducts, impaired biliary secretion, hepatocellular retention of toxic endogenous bile acids and, ultimately, the development of fibrosis leading to cirrhosis that commonly requires liver transplantation. At first sight, it seems intriguing that a bile acid could be considered for use as a therapeutic agent in a bile-acid secretion disorder. Yet, in addition to its inherently greater hydrophilic nature and competitive effect on endogenous bileacid recycling, UDCA has indeed been demonstrated to be a potent post-transcriptional secretagogue as well as a potential anti-inflammatory and anti-apoptotic agent. While the combined glucocorticoid receptor/pregnane X receptor (PXR) agonist budesonide, in combinaison with UDCA, has been shown to exert additional beneficial effects in PBC, significant progress in understanding the regulatory mechanisms involved in bile-acid homeostasis has led to the identification of nuclear [farnesoid X receptor (FXR), PXR, peroxisome proliferator-activated receptor alpha (PPARα)] and membrane (the membrane G protein-coupled bile acid receptor TGR5) receptors as critical pharmacological targets for future therapeutic approaches. Encouraging data from recent experimental and phase-II studies tend to confirm that the FXR agonist obeticholic acid and the PPARα agonists bezafibrate and fenofibrate may be used as add-on therapies in PBC patients with inadequate responses to UDCA or even as alternative first-line agents. These results could mark the beginning of a new therapeutic era for PBC.

BACKGROUND The combination of ursodeoxycholic acid (UDCA) and vitamin E is a therapeutic option for nonalcoholic steatohepatitis (NASH) but randomized controlled studies have produced inconsistent results. The objective of this study was to report the long-term tolerability and efficacy of this combination in our ten-year single center experience. METHODS The study group included 101 adult patients with persistent elevation of serum aminotransferases (AST and ALT) and/or γ glutamyl-transferase (GGT), in whom a histological diagnosis of NASH was made from January 1998 to January 2009, and who were treated with a combination of UDCA with vitamin E. RESULTS Median body mass index (30 kg/m(2)) remained unchanged during the study. UDCA and vitamin E were well tolerated (5% withdrawal for side effects). Mean serum AST, ALT and GGT levels (expressed as times of Upper Normal Limit) diminished significantly (1.39 ± 0.74 to 0.78 ± 0.34 for AST, 1.72 ± 0.92 to 0.91 ± 0.69 for AST and 3.25 ± 2.85 to 1.30 ± 1.30 for GGT). AST, ALT and GGT reached normal range in 80%, 70% and 65% of the patients, respectively. From the ten patients who had a second liver biopsy during follow-up, NAS score improved in seven, and worsened in one. CONCLUSIONS The combination of UDCA with vitamin E significantly improves liver function tests in long-term and is very well tolerated.

Abstract
Primary biliary cirrhosis (PBC) is a slowly progressive cholestatic liver disease of autoimmune etiology. The initial presentation of PBC is various from asymptomatic, abnormal liver biochemical tests to overt cirrhosis. The diagnosis of PBC is based on cholestatic biochemical liver tests, presence of antimitochondrial antibody and histologic findings of nonsuppurative destructive cholangitis. Although the diagnosis is straightforward, it could be underdiagnosed because of its asymptomatic presentation, or underrecognition of the disease. UDCA in a dose of 13-15 mg/kg is the widely approved therapy which can improve the prognosis of patients with PBC. However, one-third of patients does not respond to UDCA therapy and may require liver transplantation. Every effort to diagnose PBC in earlier stage and to develop new therapeutic drugs and clinical trials should be made.
