Indian J Endocrinol Metab 2023; 27:552-558. [PMID: 38371182 PMCID: PMC10871003 DOI: 10.4103/ijem.ijem_233_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/02/2023] [Revised: 08/30/2023] [Accepted: 09/24/2023] [Indexed: 02/20/2024] Open
Abstract
Purpose Literature on the treatment of pre-transplant hepatic osteodystrophy (HOD) is limited. The general treatment measures and their timing are currently adopted from the literature on postmenopausal osteoporosis. Therefore, we conducted this randomized study to investigate the effect of zoledronic acid (ZA) on HOD. Methods We randomized 36 male patients with cirrhosis (Child-Pugh class A and B) into 19 to the ZA arm and 17 to the placebo arm, respectively. Patients in the ZA arm received a single infusion of 4 mg ZA dissolved in 100 mL of normal saline at baseline, while patients in the placebo arm received a similar infusion of normal saline at baseline. The primary outcome of the study was the change in lumbar spine bone mineral density (LS-BMD) at 12 months. Results Of 36 patients, 28 completed the study (15 in the ZA arm and 13 in the placebo arm). The mean increase in LS-BMD (g/cm2) in the ZA and placebo arms was 5.11% (3.50) and 0.72% (4.63) [P = 0.008], respectively. The trabecular bone score (TBS) did not improve significantly in either arm. The incidence of vertebral fractures (VFs) was similar in both arms. There was a significant decrease in plasma beta-C-terminal telopeptide (β-CTX) levels in the ZA arm compared to the placebo arm, while the change in plasma levels of procollagen 1 intact N-terminal propeptide (P1NP) was similar in both arms. Six patients (31.6%) in the ZA arm experienced adverse reactions such as fever and myalgia. Conclusion ZA improved LS-BMD in male patients with HOD by decreasing bone resorption. However, it may not improve trabecular microarchitecture or prevent morphometric VFs in this population.

Abstract
Introduction Primary biliary cholangitis (PBC) is associated with an increased risk of developing fractures. Current guidelines recommend measures that can help prevent the development of fractures in these patients. The purpose of this study was to trend the rates of hospitalizations related to fractures and their burden on healthcare. Methods We performed a retrospective, cohort study of adults hospitalized in the United States with PBC between 2010 and 2014. Patients were identified using the Nationwide Inpatient Sample (NIS). Temporal analysis of PBC patients with a co-diagnosis of hip, vertebral, or wrist fractures (the study group) was performed with regards to the total number of inpatient admissions, inpatient mortality, length of stay, and total charges associated with hospitalization. Descriptive analyses were performed using the t-test for continuous data and the chi-square test for categorical data. Results During the five-year study period, there were 308,753 hospitalizations for PBC. There has been a downward trend (p=0.02) in fracture-related admissions among patients with PBC during this study period. Length of stay was higher in the PBC-fracture group (10.85 days vs 7.36 days; p<0.001). Total hospitalization charges were higher among the PBC-fracture patients when compared to the control group ($98,444 vs $72,964; p=0.004). Conclusion There has been a gradual reduction in the rate of fracture-related hospitalizations in patients with PBC. However, patients with PBC who have fractures have increased the utilization of health care resources as compared to their cohort admitted for reasons other than for a fracture.

Abstract
INTRODUCTION Osteoporosis is a common complication of primary biliary cholangitis (PBC) yet evidence for effective therapy is lacking. We sought to review all randomized controlled trials evaluating pharmacotherapy against placebo or no intervention for treatment of osteoporosis in PBC. METHODOLOGY A comprehensive database search was conducted from inception through 29 March 2017. The primary outcome was incidence of fractures; secondary outcomes were change in bone mineral density (BMD) and adverse events. We assessed studies for risk of bias, graded quality of evidence, and used meta-analysis to obtain overall effect by pooling studies of the same drug class. RESULTS We identified 11 randomized controlled trials evaluating bisphosphonates (3), hormone replacement therapy (2), ursodeoxycholic acid (1), obeticholic acid (1), cyclosporin A (1), vitamin K (1), calcitriol (1), and sodium fluoride (1). No intervention significantly reduced fractures compared to control. Although significant improvement in BMD was seen in one study with alendronate, a third-generation bisphosphonate, no significant improvement was seen on pooled analysis of all bisphosphonates including first-generation bisphosphonates (standard mean difference 0.41, p = 0.68). On pooled analysis, hormone replacement therapy modestly improved lumbar BMD (standard mean difference 0.69, p = 0.02), but with significantly increased adverse events (odds ratio 8.82, p = 0.01). CONCLUSIONS There is a lack of high-quality evidence supporting the efficacy of any treatment of osteoporosis in PBC. This may be explained by lack of power in the included studies. However, our current understanding of PBC-related osteoporosis indicates that it results from decreased bone formation, which may explain the attenuated effect of traditional antiresorptive agents. Future studies should investigate newer anabolic bone agents.

Abstract
Osteoporosis is the most common bone disease in chronic liver disease (CLD) resulting in frequent fractures and leading to significant morbidity in this population. In addition to patients with cirrhosis and chronic cholestasis, patients with CLD from other etiologies may be affected in the absence of cirrhosis. The mechanism of osteoporosis in CLD varies according to etiology, but in cirrhosis and cholestatic liver disease it is driven primarily by decreased bone formation, which differs from the increased bone resorption seen in postmenopausal osteoporosis. Direct toxic effects from iron and alcohol play a role in hemochromatosis and alcoholic liver disease, respectively. Chronic inflammation also has been proposed to mediate bone disease in viral hepatitis and nonalcoholic fatty liver disease. Treatment trials specific to osteoporosis in CLD are small, confined to primary biliary cholangitis and post-transplant patients, and have not consistently demonstrated a benefit in this population. As it stands, prevention of osteoporosis in CLD relies on the mitigation of risk factors such as smoking and alcohol use, treatment of underlying hypogonadism, and encouraging a healthy diet and weight-bearing exercise. The primary medical intervention for the treatment of osteoporosis in CLD remains bisphosphonates though a benefit in terms of fracture reduction has never been shown. This review outlines what is known regarding the pathogenesis of bone disease in CLD and summarizes current and emerging therapies.

Abstract
Primary biliary cholangitis (PBC) is a chronic, cholestatic condition associated with symptoms that directly impact the quality of life in those afflicted with the disease. In addition to pruritus and fatigue, patients with PBC may develop metabolic bone disease from reduced bone density, such as osteopenia and osteoporosis. Osteoporosis increases the risk of fractures, as well as morbidity and mortality. The prevalence of osteoporosis in PBC is expected to increase in conjunction with the rising prevalence of PBC as a whole. Timely diagnosis, prevention and management of osteoporosis are crucial in order to optimize the quality of life. There is a paucity of data evaluating the management of osteoporosis in PBC. The optimal timing for diagnosis and monitoring is not yet established and is guided by expert opinion. National guidelines recommend screening for osteoporosis at the time of diagnosis of PBC. Monitoring strategies are based on results of initial screening and individual risk factors for bone disease. Identifying reduced bone density is imperative to institute timely preventive and treatment strategies. However, treatment remains challenging as efficacious therapies are currently lacking. The data on treatment of osteoporosis in PBC are mostly extrapolated from postmenopausal osteoporosis literature. However, this data has not directly translated to useful treatment strategies for PBC-related osteoporosis, partly because of the different pathophysiological mechanisms of the two diseases. The lack of useful preventive measures and efficacious treatment strategies remains the largest pitfall that challenges the management of patients with PBC. In this review, we comprehensively outline the epidemiology, clinical implications and challenges, as well as management strategies of PBC-related osteoporosis.

Comparative assessment of sarcopenia using the JSH, AWGS, and EWGSOP2 criteria and the relationship between sarcopenia, osteoporosis, and osteosarcopenia in patients with liver cirrhosis. BMC Musculoskelet Disord 2019; 20:615. [PMID: 31878909 PMCID: PMC6933666 DOI: 10.1186/s12891-019-2983-4] [Citation(s) in RCA: 45] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/19/2019] [Accepted: 12/02/2019] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Sarcopenia and osteoporosis reduce life quality and worsen prognosis in patients with liver cirrhosis (LC). When these two complications coexist, a diagnosis of osteosarcopenia is made. We aimed to investigate the actual situations of sarcopenia, osteoporosis, osteosarcopenia, and vertebral fracture, and to clarify the relationship among these events in patients with LC. METHODS We describe a cross-sectional study of 142 patients with LC. Sarcopenia was defined according to the Japan Society of Hepatology (JSH) criteria, Asian Working Group for Sarcopenia (AWGS) criteria, and European Working Group on Sarcopenia in Older People (EWGSOP2) criteria. The skeletal muscle mass index (SMI) and handgrip strength were assessed using bioelectrical impedance analysis and a digital grip strength dynamometer, respectively. Bone mineral density (BMD) was measured using dual energy X-ray absorptiometry, and vertebral fracture was evaluated using spinal lateral X-rays. The severity of LC was assessed using the Child-Pugh classification. RESULTS Among the 142 patients, the prevalence of sarcopenia was 33.8% (48/142) according to the JSH and AWGS criteria and 28.2% (40/142) according to the EWGSOP2 criteria. The number of patients with osteoporosis, osteosarcopenia, and vertebral fracture was 49 (34.5%), 31 (21.8%), and 41 (28.9%), respectively. Multivariate analysis revealed a close association between sarcopenia and osteoporosis. Osteoporosis was independently associated with sarcopenia [odds ratio (OR) = 3.923, P = 0.010]. Conversely, sarcopenia was independently associated with osteoporosis (OR = 5.722, P < 0.001). Vertebral fracture occurred most frequently in patients with osteosarcopenia (19/31; 61.3%) and least frequently in those without both sarcopenia and osteoporosis (12/76; 15.8%). The SMI and handgrip strength values were significantly correlated with the BMD of the lumbar spine (r = 0.55 and 0.51, respectively; P < 0.001 for both), femoral neck, (r = 0.67 and 0.62, respectively; P < 0.001 for both), and total hip (r = 0.67 and 0.61, respectively; P < 0.001 for both). CONCLUSIONS Sarcopenia, osteoporosis, osteosarcopenia, and vertebral fracture were highly prevalent and closely associated with one another in patients with LC. Specifically, patients with osteosarcopenia had the highest risk of vertebral fractures. Early diagnosis of these complications is essential for treatment intervention.

Abstract
A frequent complication in liver cirrhosis is malnutrition, which is associated with the progression of liver failure, and with a higher rate of complications including infections, hepatic encephalopathy and ascites. In recent years, the rising prevalence of obesity has led to an increase in the number of cirrhosis cases related to non-alcoholic steatohepatitis. Malnutrition, obesity and sarcopenic obesity may worsen the prognosis of patients with liver cirrhosis and lower their survival. Nutritional monitoring and intervention is therefore crucial in chronic liver disease. These Clinical Practice Guidelines review the present knowledge in the field of nutrition in chronic liver disease and promote further research on this topic. Screening, assessment and principles of nutritional management are examined, with recommendations provided in specific settings such as hepatic encephalopathy, cirrhotic patients with bone disease, patients undergoing liver surgery or transplantation and critically ill cirrhotic patients.

Abstract
Primary biliary cholangitis (PBC) is an autoimmune cholestatic liver disease with multiple debilitating complications. Osteoporosis is a common complication of PBC resulting in frequent fractures and leading to significant morbidity in this population, yet evidence for effective therapy is lacking. We sought to summarize our current understanding of the pathophysiology of osteoporosis in PBC, as well as current and emerging therapies in order to guide future research directions. A complete search with a comprehensive literature review was performed with studies from PubMed, EMBASE, Web of Science, Cochrane database, and the Countway Library. Osteoporosis in PBC is driven primarily by decreased bone formation, which differs from the increased bone resorption seen in postmenopausal osteoporosis. Despite this fundamental difference, current treatment recommendations are based primarily on experience with postmenopausal osteoporosis. Trials specific to PBC-related osteoporosis are small and have not consistently demonstrated a benefit in this population. As it stands, prevention of osteoporosis in PBC relies on the mitigation of risk factors such as smoking and alcohol use, as well as encouraging a healthy diet and weight-bearing exercise. The primary medical intervention for the treatment of osteoporosis in PBC remains bisphosphonates though a benefit in terms of fracture reduction has never been shown. This review outlines what is known regarding the pathogenesis of bone disease in PBC and summarizes current and emerging therapies.

Abstract
Osteoporosis, characterized by compromised bone strength leading to fragility fractures, is a common event in patients with primary biliary cholangitis (PBC). Osteomalacia, defined by poor bone mineralization is very uncommon. The pathogenesis of osteoporosis is not well clarified, but it mainly results from low bone formation. Few reports have revealed increased bone resorption, particularly in end-stage disease. The prevalence of osteoporosis is about 35% in the most significant studies, and it depends on the diagnostic criteria and severity of liver damage. Osteoporosis is associated with age, postmenopausal status, duration of PBC and advanced histological stage. Bone densitometry is the common method for the diagnosis of osteoporosis and should be performed in all patients with PBC. Lateral X-rays of the dorsal and lumbar spine should also be carried out to disclose vertebral fractures. There is no specific treatment but bisphosphonates, especially alendronate and ibandronate, efficiently increases bone mass and prevents bone loss. Despite these positive effects on bone mass no clear results on decreasing the fracture rate have been demonstrated, probably because the low number of patients included in the trials. The potential value of new agents requires further evaluation.

Abstract
Osteoporosis is a frequent complication in patients with chronic liver disease, especially in end-stages and in chronic cholestasis, in addition to non-alcoholic fatty liver disease, haemochromatosis and alcoholism. Mechanisms underlying osteoporosis are poorly understood, but osteoporosis mainly results from low bone formation. In this setting, sclerostin, a key regulator of the Wnt/β-catenin signalling pathway which regulates bone formation, in addition to the effects of the retained substances of cholestasis such as bilirubin and bile acids on osteoblastic cells, may influence the decreased bone formation in chronic cholestasis. Similarly, the damaging effects of iron and alcohol on osteoblastic cells may partially explain bone disease in haemochromatosis and alcoholism. A role for proinflammatory cytokines has been proposed in different conditions. Increased bone resorption may occur in cholestatic women with advanced disease. Low vitamin D, poor nutrition and hypogonadism, may be contributing factors to the full picture of bone disorders in chronic liver disease.

Abstract
UNLABELLED Osteoporosis resulting in bone fractures is a complication in patients with primary biliary cirrhosis (PBC). Once-weekly alendronate improves bone mass and is well tolerated in these patients, but there is a concern because of poor compliance. Therefore, the efficacy, adherence, and safety of monthly ibandronate (150 mg) with weekly alendronate (70 mg) were compared in a randomized, 2-year study in 42 postmenopausal women with PBC and osteoporosis. Bone mineral density (BMD) of the lumbar spine and proximal femur (by DXA), liver function, and bone markers were measured at entry and every 6 months over 2 years. Adherence to therapy was assessed by the Morisky-Green score. At enrollment, the two groups were similar with respect to age, BMD, severity of cholestasis, previous fractures, and bone markers. Thirty-three patients, 14 in the ibandronate group and 19 in the alendronate group, completed the trial. At 2 years both treatments resulted in a significant increase in BMD at the lumbar spine (from 0.875 ± 0.025 to 0.913 ± 0.026 g/cm(2), P < 0.001 with alendronate, and from 0.898 ± 0.024 to 0.949 ± 0.027 g/cm(2), P < 0.001 with ibandronate). The mean percentage change was 4.5% and 5.7%, respectively (P = not significant). BMD increased at the total hip by 2.0% and 1.2%, respectively. Changes in bone markers were similar in both groups and one patient with alendronate developed a new vertebral fracture. Adherence to therapy was higher with ibandronate (P = 0.009). Neither treatment impaired liver function or cholestasis. CONCLUSION Both regimens, weekly alendronate and monthly ibandronate, improve bone mass and are comparable in safety for osteoporosis therapy in patients with PBC, although adherence is higher with the monthly regimen. Further larger studies are needed to assess fracture prevention.

Abstract
BACKGROUND Bisphosphonates are widely used for treatment of postmenopausal osteoporosis. Patients with primary biliary cirrhosis often have osteoporosis - either postmenopausal or secondary to the liver disease. No systematic review or meta-analysis has assessed the effects of bisphosphonates for osteoporosis in patients with primary biliary cirrhosis. OBJECTIVES To assess the beneficial and harmful effects of bisphosphonates for osteoporosis in primary biliary cirrhosis. SEARCH METHODS 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, the WHO International Clinical Trials Registry Platform, and full text searches were conducted until November 2011. Manufacturers and authors were contacted for additional studies during the conductance of the review. SELECTION CRITERIA All randomised clinical trials of bisphosphonates in primary biliary cirrhosis compared with placebo or no intervention, or another bisphosphonate, or any other drug. DATA COLLECTION AND ANALYSIS Two authors extracted data. RevMan Analysis was used for statistical analysis of dichotomous data with risk ratio (RR) or risk difference (RD) and of continuous data with mean difference (MD) or standardised mean difference (SMD), all with 95% confidence intervals (CI). Methodological components were used to assess risk of systematic errors (bias). Trial sequential analysis was also used to control for random errors (play of chance). MAIN RESULTS Six trials were included. Three trials with 106 participants, of which two trials with high risk of bias, did not demonstrate significant effects of bisphosphonates (etidronate or alendronate) versus placebo or no intervention regarding mortality (RD 0.00; 95% CI -0.12 to 0.12, I² = 0%), fractures (RR 0.87; 95% CI 0.29 to 2.66, I² = 0%), or adverse events (RR 1.00; 95% CI 0.49 to 2.04). Two trials with 62 participants with high risk of bias compared one bisphosphonate (etidronate or alendronate) versus another (alendronate or ibandronate) and found no significant difference regarding mortality (RD -0.03; 95% CI -0.14 to 0.07, I² = 0%), fractures (RR 0.95; 95% CI 0.18 to 5.06, I² = 0%), or adverse events (RR 1.00; 95% CI 0.49 to 2.04, I² = 0%). Bisphosphonates had no significant effect on liver-related mortality, liver transplantation, or liver-related morbidity compared with placebo or no intervention, or another bisphosphonate. Bisphosphonates had no significant effect on bone mineral density compared with placebo or no intervention, or another bisphosphonate. Bisphosphonates compared with placebo or no intervention seem to decrease the urinary amino telopeptides of collagen I (NTx) concentration (MD -16.93 nmol bone collagen equivalents/mmol creatinine; 95% CI -23.77 to -10.10; 2 trials with 88 patients; I² = 0%) and serum osteocalcin (SMD -0.81; 95% CI -1.22 to -0.39; 3 trials with 100 patients; I² = 34 %) concentration. The former result was supported by trial sequential analysis, but not the latter. Alendronate compared with another bisphosphonate (ibandronate) had no significant effect on serum osteocalcin concentration (MD -3.61 ng/ml, 95% CI -9.41 to 2.18; 2 trials with 47 patients; I² = 82%) in a random-effects meta-analysis, but it significantly decreased serum osteocalcin (MD -4.40 ng/ml, 95% CI -6.75 to -2.05; 2 trials with 47 patients; I² = 82%), the procollagen type I N-terminal propeptide (MD -8.79 ng/ml, 95% CI -15.96 to -1.63; 2 trials with 47 patients; I² = 38%), and NTx concentration (MD -14.07 nmol bone collagen equivalents/mmol creatinine, 95% CI -24.23 to -3.90; 2 trials with 46 patients; I²=0%) in a fixed-effect model. The latter two results were not supported by trial sequential analyses. There was no statistically significant difference in the number of patients having bisphosphonates withdrawn due to adverse events compared with placebo or no intervention (RD -0.04; 95% CI -0.21 to 0.12; 2 trials with 46 patients; I² = 0%), or another bisphosphonate (RR 0.56; 95% CI 0.14 to 2.17; 2 trials with 62 patients; I² = 0%). One trial with 32 participants and with high risk of bias compared etidronate versus sodium fluoride without finding significant difference regarding mortality, fractures, adverse events, or bone mineral density. Etidronate compared with sodium fluoride significantly decreased serum osteocalcin, urinary hydroxyproline, and parathyroid hormone concentration. AUTHORS' CONCLUSIONS We did not find evidence to support or refute the use of bisphosphonates for patients with primary biliary cirrhosis. The data seem to indicate a possible positive intervention effect of bisphosphonates on decreasing urinary amino telopeptides of collagen I concentration compared with placebo or no intervention with no risk of random error. There is need for more randomised clinical trials assessing the effects of bisphosphonates for osteoporosis on patient-relevant outcomes in primary biliary cirrhosis.

Abstract
BACKGROUND AND AIMS Metabolic bone disease is common in patients with chronic liver disease. Comparative studies on the efficacies of antiosteoporotic agents in hepatic osteodystrophy have not been conducted yet. The aim of this study was to evaluate the safety and efficacy of different therapeutic regimens on hepatic osteodystrophy. METHODS Eighty-one patients (mean age 48.9 ± 10 years; 50 cases with chronic viral hepatitis and 31 patients with cirrhosis) were enrolled in the study. Treatment groups consisted of 61 patients who had reduced T scores in at least one region, selected randomly and treated for 1 year with vitamin D 400 IU, calcitonin 200 IU, alendronate 10 mg, alendronate 70 mg, or risedronate 5 mg. An untreated group consisting of 20 patients who had no reduction in T scores was followed up during the study period. RESULTS No significant adverse effects, including esophageal variceal hemorrhage, were detected. According to the T score at the end of the first year compared with baseline, significant improvements in bone mineral density were observed at all regions with alendronate 70 mg; improvements at the lumbar spine (LS) and distal radius regions with alendronate 10 mg; at the LS and distal radius regions with risedronate; at the LS region with calcitonin; and at the femoral neck region with vitamin D. CONCLUSION All therapeutic regimens seemed to be safe, and oral biphosphonates were the most effective in preventing both cortical and trabecular bone loss in patients with chronic viral liver disease. Larger studies with longer follow-up are warranted in hepatic osteodystrophy of chronic viral liver diseases.

Abstract
Osteoporosis resulting in a high risk for fracture is a common complication in patients with liver disease, particularly in those with chronic cholestasis and with end-stage cirrhosis. The pathogenesis of bone loss in liver patients is poorly understood but it mainly results from low bone formation as a consequence of cholestasis or the harmful effects of alcohol or iron on osteoblasts. Increased bone resorption has also been described in cholestatic women with advanced disease. The management of bone disease in liver patients is addressed to reduce or avoid the risk factors for osteoporosis and fracture. Bisphosphonates associated with supplements of calcium and vitamin D are safe and effective for increasing bone mass in patients with chronic cholestasis and after liver transplantation, though no clear achievements in descreasing the incidence of fractures have been described, probably because of the low number of patients included in the therapeutic trials. Randomized studies assessing bisphosphonates in larger series of patients, the development of new drugs for osteoporosis and the improvement in the management of liver transplant recipients may change the future.

Abstract
Osteoporosis is a frequent complication in patients with chronic liver disease, especially in end-stages and in cases with chronic cholestasis, hemochromatosis and alcohol abuse. The problem is more critical in transplant patients when bone loss is accelerated during the period immediately after transplantation, leading to a greater incidence of fractures. Advanced age, low body mass index and severity of the liver disease are the main risk factors for bone disease in patients with cholestasis. Mechanisms underlying osteoporosis in chronic liver disease are complex and poorly understood, but osteoporosis mainly results from low bone formation, related to the effects of retained substances of cholestasis, such as bilirubin and bile acids, or to the effects of alcohol on osteoblastic cells. Increased bone resorption has also been described in cholestatic women with advanced disease. Although there is no specific treatment, bisphosphonates associated with supplements of calcium and vitamin D are effective for increasing bone mass in patients with chronic cholestasis and after liver transplantation. The outcome in reducing the incidence of fractures has not been adequately demonstrated essentially because of the low number of patients included in the therapeutic trials. Randomized studies assessing bisphosphonates in larger series of patients, the development of new drugs for osteoporosis and the improvement in the management of liver transplant recipients may change the future.

Abstract
IMPORTANCE OF THE FIELD Primary biliary cirrhosis is a cholestatic liver disease that at one time was the leading indication for liver transplantation. Treatment with ursodeoxycholic acid has clearly improved the natural history of primary biliary cirrhosis. AREAS COVERED IN THIS REVIEW The treatment of primary biliary cirrhosis with a focus on ursodeoxycholic acid is covered. Papers related to treatment of primary biliary cirrhosis and associated conditions, using a variety of drugs but with a focus on ursodeoxycholic acid, are included. The papers reviewed date from 1984 - 2009. WHAT WILL THE READER GAIN The reader will gain an up-to-date understanding of current treatment strategies for primary biliary cirrhosis using ursodeoxycholic acid and an appreciation of what conditions are improved with this therapy and what associated conditions are not. TAKE-HOME MESSAGE Ursodeoxycholic acid in a dose of 13 - 15 mg/kg/day should be considered in all patients with primary biliary cirrhosis who have abnormal liver enzymes.

Abstract
Primary biliary cirrhosis (PBC) is an immune-mediated chronic cholestatic liver disease with a slowly progressive course. Without treatment, most patients eventually develop fibrosis and cirrhosis of the liver and may need liver transplantation in the late stage of disease. PBC primarily affects women (female preponderance 9–10:1) with a prevalence of up to 1 in 1,000 women over 40 years of age. Common symptoms of the disease are fatigue and pruritus, but most patients are asymptomatic at first presentation. The diagnosis is based on sustained elevation of serum markers of cholestasis, i.e., alkaline phosphatase and gamma-glutamyl transferase, and the presence of serum antimitochondrial antibodies directed against the E2 subunit of the pyruvate dehydrogenase complex. Histologically, PBC is characterized by florid bile duct lesions with damage to biliary epithelial cells, an often dense portal inflammatory infiltrate and progressive loss of small intrahepatic bile ducts. Although the insight into pathogenetic aspects of PBC has grown enormously during the recent decade and numerous genetic, environmental, and infectious factors have been disclosed which may contribute to the development of PBC, the precise pathogenesis remains enigmatic. Ursodeoxycholic acid (UDCA) is currently the only FDA-approved medical treatment for PBC. 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. The mode of action of UDCA is still under discussion, but stimulation of impaired hepatocellular and cholangiocellular secretion, detoxification of bile, and antiapoptotic effects may represent key mechanisms. One out of three patients does not adequately respond to UDCA therapy and may need additional medical therapy and/or liver transplantation. This review summarizes current knowledge on the clinical, diagnostic, pathogenetic, and therapeutic aspects of PBC.

Abstract
Primary sclerosing cholangitis (PSC) is a chronic, progressive, cholestatic liver disease characterized by inflammation and fibrotic obliteration of the hepatic biliary tree. It is commonly associated with inflammatory bowel disease (IBD). A number of complications can occur which require special consideration, the most important of which is the development of cholangiocellular carcinoma (CCC). Unfortunately, no medical therapy is currently available for the underlying liver disease. Liver transplantation is an effective, life-extending option for patients with advanced PSC. Geographical variations between East and West include a second peak for age with a lower association with IBD in a Japanese population and female predominance in a lone study from Turkey. The clinical and biochemical Mayo criteria may not be universally applicable, as different patients show variations regarding the initial presentation and natural course of the disease. Directing research towards explaining these geographical differences and understanding the pathogenesis of PSC is required in order to develop better therapies for this devastating disease.

Abstract
Primary biliary cirrhosis (PBC), which is characterized by progressive destruction of intrahepatic bile ducts, is not a rare disease since both prevalence and incidence are increasing during the last years mainly due to the improvement of case finding strategies. The prognosis of the disease has improved due to both the recognition of earlier and indolent cases, and to the wide use of ursodeoxycholic acid (UDCA). New indicators of prognosis are available that will be useful especially for the growing number of patients with less severe disease. Most patients are asymptomatic at presentation. Pruritus may represent the most distressing symptom and, when UDCA is ineffective, cholestyramine represents the mainstay of treatment. Complications of long-standing cholestasis may be clinically relevant only in very advanced stages. Available data on the effects of UDCA on clinically relevant end points clearly indicate that the drug is able to slow but not to halt the progression of the disease while, in advanced stages, the only therapeutic option remains liver transplantation.

Abstract
Osteoporosis, characterized by loss of bone strength leading to fragility fractures, is a common event in patients who have primary biliary cirrhosis. Although its pathogenesis is not well known, it results mainly from low bone formation. There is no specific treatment, but bisphosphonates, especially alendronate, effectively increases bone mass and prevents bone loss. Despite these favorable effects on bone mass, no clear effects on decreasing the fracture rate are demonstrated, probably because of the low number of patients included in the trials. The potential usefulness of new agents requires further evaluation.

Abstract
In most cholestatic liver diseases the cause of the disease is not known and therapy can only be directed toward suppression of the pathogenetic processes and amelioration of the consequences of cholestasis. The recognition of adaptive-compensatory responses to cholestasis has become of major importance. They tend to minimize retention of bile acids and other potentially toxic solutes in the hepatocyte by limiting hepatocellular uptake, reducing bile acid synthesis, stimulating detoxification, and up-regulating alternative pathways for excretion. Some of the drugs used for the treatment of cholestatic liver diseases in an empiric way turned out to be modulators of nuclear receptors, which regulate these adaptive-compensatory responses. New drugs are being designed and tested along these lines and may be regarded as treatment opportunities of the future.

Abstract
Osteoporosis is a common complication of chronic liver disease, from cholestatic disorders to autoimmune, alcoholic, and posthepatitic cirrhosis. Osteoporosis appears more striking in patients with primary biliary cirrhosis (PBC) because the disease usually affects elderly women, who are naturally prone to osteoporosis. Our aims were (1) to compare the prevalence of osteoporosis (T-score <-2.5 SD) between PBC patients and a group of age-and sex-matched controls consisting of healthy subjects from the general population; and (2) to identify the main risk factors for the development of bone loss. Thirty-three women with PBC (mean age, 47.3 +/- 10.4 years) and 66 healthy subjects were enrolled in the study. Bone mineral density (BMD) was assessed at the lumbar spine by dual-photon X-ray absorptiometry. Bone metabolism was evaluated by measuring serum calcium corrected for serum albumin, 25-hydroxyvitamin D (25-OH vit D), parathyroid hormone, and osteocalcin. Vertebral fractures were analyzed using vertebral fracture assessment (VFA). The mean T-score was lower in the PBC group compared to healthy controls, with a significant statistical difference (-2.39 +/- 0.93 and -1.47 +/- 0.99 in lumbar spine and total hip, respectively, in the PBC group versus -0.99 +/- 0.51 and -0.56 +/- 1.14 in healthy controls (P < 0.001). The prevalence of osteoporosis was 51.5% in the PBC group versus 22.7% in healthy controls with a statistically significant difference (P = 0.004). BMD of the PBC group was significantly correlated positively with body mass index (BMI) and 25-OH vit D, and negatively with menopausal status, duration of disease, and parathyroid hormone (PTH) levels. Vertebral fractures were present in 9% of the patients. We found that osteoporosis is more prevalent in women with PBC than in the general population. BMI, menopausal status, duration of the disease, and vitamin D deficiency are the main risk factors for osteoporosis in this liver disease.

Abstract
BACKGROUND & AIMS Reduced bone mass and increased fracture rate are complications of primary biliary cirrhosis (PBC). The effect of intermittent administration of human parathyroid hormone (hPTH) 1-34 on bone mass and architecture in bile duct-ligated (BDL) rats was studied. METHODS Six-month-old male rats were subjected to BDL or sham operation (SO) and were treated from the second postoperative week intermittently with either hPTH 1-34 40 microg/kg per day, 80 microg/kg per day, or a vehicle for 4 weeks. Femoral and tibial bones were evaluated ex vivo by dual x-ray absorptiometry, microcomputed tomography, and histomorphometry. Serum osteocalcin and urinary deoxypyridinoline cross-links (DPD) were determined. RESULTS BDL rats had decreased bone mass compared with SO rats as indicated by a 6% decrease in femoral and tibial bone mineral density (BMD), 18% reduction in femoral trabecular bone volume (bone volume/total volume [BV/TV]), 17% decrease in trabecular thickness, and 10% decrease in tibial cortical thickness. The administration of hPTH 1-34 at 40 microg/kg per day increased femoral and tibial BMD (9% and 9%), femoral trabecular BV/TV (50%), trabecular thickness (50%), tibial cortical thickness (17%), and serum osteocalcin (82%). On the other hand, hPTH 1-34 80 microg/kg per day had no effect on BMD and tibial cortical thickness, was associated with a smaller increase in trabecular BV/TV (24%), and had a higher osteoclast number and DPD compared with untreated BDL rats and the lower hPTH 1-34 dose treatment group. CONCLUSIONS BDL rats exhibit loss of bone mass and structure, which can be prevented by the intermittent administration of hPTH 1-34, a potential therapy for osteoporosis in PBC.

Abstract
BACKGROUND/AIM To evaluate the safety of budesonide in primary biliary cirrhosis. METHODS 77 primary biliary cirrhosis patients, with stages I-III at entry, were randomized to use either budesonide 6 mg and ursodeoxycholic acid 15 mg/kg (group A), or ursodeoxycholic acid alone (group B) daily for 3 years. In 22 patients, budesonide pharmacokinetics was determined after 3 years. Bone mass density was measured in 62 patients at baseline and 3 years; in 57 patients also liver biopsies were performed. RESULTS At 3 years, no significant differences in the pharmacokinetics of budesonide were found between the patients with stages 0-I, II and III primary biliary cirrhosis. In group A, bone mass density in femoral neck and lumbar spine were decreased by 3.6% (P = 0.0002) and 2.8% (P = 0.003) from the baseline. In group B, the corresponding decreases were 1.9% (P = 0.029) and 0.7% (P = 0.25), but the differences between the groups were not statistically significant (P = 0.16 for femoral neck and P = 0.08 for lumbar spine). CONCLUSIONS The plasma concentrations of budesonide do not significantly differ within stages I-III primary biliary cirrhosis patients. The combination of budesonide and ursodeoxycholic acid may decrease bone mass density in the femoral neck and lumbar spine in some primary biliary cirrhosis patients, and bone mass density is recommended to be monitored during budesonide therapy.

Abstract
BACKGROUND & AIMS Controversy exists as to whether people with primary biliary cirrhosis (PBC) have an increased risk of developing osteoporosis and the extent to which this may translate into an increased risk of fracture. We have performed a cohort study using the General Practice Research Database to quantify the excess fracture risk in people with PBC. METHODS We identified 930 people with PBC and 9202 age- and sex-matched control subjects. We used Cox regression to estimate the hazard ratios for any fracture, hip fracture, and ulna/radius fracture in the PBC cohort compared with the general population. RESULTS There were approximately 2-fold relative increases in the risk of any fracture, hip fracture, and ulna/radius fracture for the PBC cohort compared with the general population (hazard ratio [HR], 2.03; 95% confidence interval [CI]: 1.70-2.44; HR 2.14 (95% CI: 1.40-3.28), and HR, 1.96; 95% CI: 1.42-2.71, respectively). The absolute excess in fracture rates were for any fracture, 12.5 per 1000 person-years (95% CI: 8.1-16.9); for hip fracture, 1.9 per 1000 person-years (95% CI: 0.3-3.5); and for ulna/radius fracture, 3.4 per 1000 person-years (95% CI: 1.2-5.7). In those people with more severe disease, the relative risks of fracture were similar (any fracture HR, 2.24; hip fracture HR, 1.25; ulna/radius fracture HR, 1.28). CONCLUSIONS There are modest increases in both the absolute and relative fracture risks in people with PBC compared with the general population, with the excess risks similar in those with more severe disease.

Abstract
The optimal therapy for the prevention and treatment of osteoporosis in primary biliary cirrhosis (PBC) is unknown. Hormone replacement therapy (HRT) prevents osteoporosis, but may promote cholestasis. We performed a double-blind, randomized, placebo-controlled trial of transdermal estrogen/progestin in postmenopausal women with PBC. The 24-month study enrolled 31 patients, but trial uptake was limited and treatment arm dropout was significant. Placebo-treated patients had a higher percentage loss in femoral neck bone mineral density than actively treated patients (-3.76 +/- 1.37% versus 0.21 +/- 1.01%, respectively, P = .058). New fractures occurred in 2 patients on placebo, and in no patients on treatment. The mean monthly increase in bilirubin was not significantly different between groups, but individual data suggest HRT may worsen cholestasis. In conclusion, women with PBC have strong feelings about HRT, and recruitment for this intervention is difficult. Transdermal estrogen/progestin likely provides protection against bone loss in PBC patients, but may worsen cholestasis.

Abstract
Bone loss is a well-recognized complication of primary biliary cirrhosis (PBC). Although it has been suggested that alendronate might improve bone mineral density (BMD) in PBC, no randomized placebo-controlled trial has been conducted. The primary aim of this study was to compare the effects of alendronate versus placebo on BMD and biochemical measurements of bone turnover in patients with PBC-associated bone loss. We conducted a double-blinded, randomized, placebo-controlled trial. Patients with a PBC and BMD t score of less than -1.5 were randomized to receive 70 mg per week of alendronate or placebo over 1 year. BMD of the lumbar spine and proximal femur were measured at entry and at 1 year. Changes from baseline in BMD and biochemical measurements of bone turnover were assessed. Thirty-four patients were enrolled. Seventeen patients were randomized to each arm. After 1 year, a significantly larger improvement (P = .005) in spine BMD was observed in the alendronate group (0.09 +/- 0.03 g/cm2 SD from baseline) compared with the placebo group (-0.003 +/- 0.02 g/cm2 SD from baseline). A larger improvement (P = .046) was also observed in the femoral BMD of alendronate patients versus placebo. BMD changes were independent of concomitant estrogen therapy. The rate of adverse effects was similar in both groups. In conclusion, in patients with PBC-related bone loss, alendronate significantly improves BMD compared with placebo. Although in this study oral alendronate appears to be well tolerated in patients with PBC, larger studies are needed to formally evaluate safety.

Abstract
AIM Patients with primary biliary cirrhosis may be at increased risk of osteoporosis but to what extent this is reflected in an increased fracture risk is unknown. We have enquired about the fracture experience of female primary biliary cirrhosis patients compared with sex- and age-matched controls. METHODS Patients aged 30-75 with primary biliary cirrhosis and age-matched controls were sent a postal questionnaire asking about their fracture history and details of risk factors for osteoporosis. RESULTS 85 eligible patients with primary biliary cirrhosis and 116 controls responded. Forty-one per cent of patients with primary biliary cirrhosis and 30% of controls reported ever having had a fracture odds ratio 1.5 (95% confidence interval: 0.80-2.89). Twenty-eight per cent of primary biliary cirrhosis patients and 23.3% of controls reported a fracture after the age of 30, odds ratio 1.2 (95% confidence interval: 0.57-2.56), and 14.1% of primary biliary cirrhosis patients and 12.1% of controls reported a low impact fracture of the long bones or of the vertebrae odds ratio 1.0 (95% confidence interval: 0.31-2.68). CONCLUSIONS No overall increased fracture risk in patients with primary biliary cirrhosis was observed. As a group, unselected patients with primary biliary cirrhosis do not represent a population at particularly high risk of osteoporotic fracture and thus targeting them for osteoporosis screening and treatment is not justified. Further work investigating subgroups of patients with primary biliary cirrhosis at potentially high risk of osteoporosis, such as those with advanced disease or severe cholestasis is required.

Abstract
OBJECTIVES The prevalence of osteoporosis amongst patients with primary biliary cirrhosis (PBC) is high and may be a serious clinical problem. Hormone replacement therapy (HRT) is effective in preventing bone loss but has not been evaluated in randomized trials in PBC. The primary aim was to study the effect of transdermal HRT in combination with daily vitamin D and calcium supplementation on bone loss compared with vitamin D and calcium supplementation only in postmenopausal women with PBC. The secondary aim was to study the safety of transdermal HRT. SUBJECTS/INTERVENTIONS Eighteen females with PBC were randomized to receive 2 years therapy with either (i) transdermal oestradiol 50 microg 24 h(-1) two times per week + medroxyprogesterone 2.5 mg day(-1) + alfacalcidol 0.25 microg day(-1) and calcium 1 g day(-1) or (ii) alfacalcidol 0.25 microg day(-1) and calcium 1 g day(-1). Dual-energy X-ray absorptiometry for measurement of bone mineral density (BMD) and sampling of blood and serum for measurements of biochemical markers of liver function was performed before, during and at the end of treatment. RESULTS BMD increased significantly at the lumbar spine (P < 0.05) and the femoral neck (P < 0.05) in the HRT group whereas no significant change was found in the control group. One oestrogen-treated patient was excluded after 1 year because of deteriorating, but reversible, aminotransferases. Dropout frequency because of nonliver-related causes was higher in the HRT group. Otherwise, no difference with respect to adverse liver reactions was found between the groups. CONCLUSION Transdermal HRT increases BMD in PBC patients with few severe side effects related to the liver.

Abstract
Primary biliary cirrhosis is a chronic, progressive disease for which there is no definitive treatment. Ursodeoxycholic acid, however, is of benefit for delaying progression to irreversible end-stage liver disease and prolonging survival free of transplantation. It is, therefore, the standard medical therapy for primary biliary cirrhosis. Orthotopic liver transplantation can be offered for patients with end-stage disease. Other important endpoints of treatment in this condition include management of the long-term complications of cholestasis such as pruritus, osteoporosis, and fat-soluble vitamin deficiencies. Pruritus is best treated with cholestyramine; rifampicin, antihistaminics, opioid-antagonists, and ondansetron can also be tried. Osteoporosis should be treated with calcium and vitamin D supplementation. Bisphosphonates or vitamin K2 may be of additional benefit to decrease the risk of fractures, but this is unproved as of yet. Deficiencies of vitamins A, D, E, and K should be treated with appropriate replacement. Finally, orthotopic liver transplant is indicated for cases of liver failure, intractable pruritus, or severe osteoporosis.

Abstract
Osteoporosis is several times more common in patients with PBC compared with the general population. Maintaining adequate intake of calcium and vitamin D is important for prevention of bone loss. The use of bisphosphonates or vitamin K to improve bone mineral density in osteopenic patients seems promising and needs to be further evaluated. Patients with PBC may develop fat-soluble vitamin deficiencies, especially vitamins A and D; serum levels should be investigated in patients considered at risk with the aim of recommending appropriate replacement therapy. Finally, hyperlipidemia in PBC does not seem to be associated with an increased risk of atherogenesis. New therapies in this patient population are currently under investigation.

Abstract
Primary biliary cirrhosis is a chronic cholestatic liver disease of adults. This disorder is characterised histologically by chronic non-suppurative destruction of interlobular bile ducts leading to advanced fibrosis, cirrhosis, and liver failure. The precise aetiopathogenesis of primary biliary cirrhosis remains unknown, although dysregulation of the immune system and genetic susceptibility both seem to be important. Affected patients are typically middle-aged women with abnormal serum concentrations of alkaline phosphatase. Presence of antimitochondrial antibody in serum is almost diagnostic of the disorder. Identification of primary biliary cirrhosis is important, because effective treatment with ursodeoxycholic acid has been shown to halt disease progression and improve survival without need for liver transplantation. However, therapeutic options for disease-related complications-including fatigue and metabolic bone disease-remain unavailable. Mathematical models have been developed that accurately predict the natural history of primary biliary cirrhosis in individuals. Despite advances in understanding of the disease, it remains one of the major indications for liver transplantation worldwide.

Abstract
BACKGROUND Osteoporosis is a recognized complication of primary biliary cirrhosis but it has been suggested that its prevalence may overlap that observed among postmenopausal women. AIM To evaluate prevalence and risk factors of osteoporosis in primary biliary cirrhosis. PATIENTS A total of 133 female patients (age 53+/-10 years, menopausal status 70%, histological stage I-II 61%, portal hypertension 28%, Mayo Risk Score 4.11+/-0.59) were enrolled. METHODS Dual X-ray absorptiometry of the lumbar spine. RESULTS Mean bone mineral density, T and Z score were 0.861+/-0.160 g/cm2, -1.87+/-1.45 and -0.78+/-2.63, respectively. At multivariate analysis, bone mineral density was inversely correlated with age (p<0.05). Osteoporosis was present in 39/92 (41%) postmenopausal and 8/41 (20%) premenopausal patients. In the premenopausal group, osteoporosis was significantly correlated with serum albumin (p<0.05) and Mayo Risk score (p<0.005). No significant correlation was present in the postmenopausal group. CONCLUSIONS Despite the accepted wisdom that osteoporosis is a common complication of primary biliary cirrhosis, its frequency in post-menopausal patients overlaps that observed in the general population, but is much more frequent in premenopausal patients, where it appears to be related to severity of liver disease and cholestasis.

Abstract
OBJECTIVE Estrogen therapy has been found to be useful in the treatment of postmenopausal osteoporosis. However, concern about its potential for worsening cholestasis has limited its use in postmenopausal women with primary biliary cirrhosis. The aim of the present study was to determine the safety as well as the efficacy of estrogen replacement therapy with respect to bone mass in postmenopausal women with primary biliary cirrhosis. METHODS Bone mineral density of the lumbar spine (measured using dual energy x-ray absorptiometry) of 46 unselected postmenopausal women with primary biliary cirrhosis receiving estrogen replacement therapy was compared with 46 age-matched women with primary biliary cirrhosis not receiving estrogen replacement therapy, and with the expected normal bone mineral density adjusted for age and ethnic group. RESULTS The mean duration of follow-up was 4.8 +/- 0.4 yr. Treatment with estrogens resulted in a significantly lower rate of bone loss (0.002 g/cm(2)/yr +/- 0.028 vs 0.009 g/cm(2)/yr +/- 0.020, p = 0.05). Worsening cholestasis attributable to estrogen replacement therapy did not occur in any patient. One patient (2%) discontinued therapy because of side effects. CONCLUSIONS Estrogen replacement therapy in postmenopausal patients with primary biliary cirrhosis is safe and may be effective in decreasing the rate of bone loss.

Abstract
The coexistence of liver disease and osteopenic bone disease has been recognized for many years and is now the subject of increasing attention. Osteoporosis has been characterized well in patients with cholestatic liver disease, but new research suggests that osteopenia and osteoporosis may also be prevalent in patients with other chronic liver diseases. Although the precise mechanism of bone loss remains unclear, advances in treatment and prevention are bringing heightened awareness to this common problem.

Abstract
Pruritus, fatigue and metabolic bone disease represent three major extrahepatic manifestations of chronic cholestatic liver disease that considerably affect the patient's quality of life. The present article reviews pathogenetic aspects of and current therapeutic approaches to extrahepatic manifestations of cholestatic liver disease. Pathogenesis of pruritus of cholestasis remains poorly understood. The involvement of putative peripherally acting pruritogens, such as bile acids or endogenous opioids, is being discussed. More recently, central mechanisms, including an increased central opioidergic tone and pertubations in the serotonergic system have been proposed. Treatment of the underlying disease is beneficial also for the control of cholestasis-associated pruritus. Current therapeutic recommendations include ursodeoxycholic acid, cholestyramine, rifampicin and opioid antagonists. Liver transplantation may be indicated when severe pruritus is refractory to medical treatment. Fatigue is being recognized as the most frequent and one of the most disabling complaints in chronic cholestasis. Fatigue is presumably of central origin and its association with other neuropsychiatric disorders (e.g. depression, obsessive-compulsive disorders) is consistent with defective central neurotransmission. No specific therapies are currently available and a healthy lifestyle, regular sleep and avoidance of unnecessary stress and other precipiting factors are recommended. Antidepressant therapy may be warranted in selected patients. Osteopenia and osteoporosis are common in chronic cholestatic liver disease, whereas osteomalacia is rare. The pathophysiology of cholestasis-associated metabolic bone disease is regarded as multifactorial. Therapeutic recommendations include regular exercise, calcium and vitamin D supplementation in late stage disease, hormone replacement therapy in postmenopausal women and bisphosphonates.

Abstract
Osteopenia is a classic complication of chronic cholestasis related to primary biliary cirrhosis or primary sclerosing cholangitis. Most studies were done in patients with primary biliary cirrhosis, which is by far the more common of the two diseases. Estrogen deficiency may be the main cause of bone loss in these patients, most of whom are perimenopausal women. Liver disease severity does not seem to play a major role, although a high bone turnover rate is seen in some patients before the menopause. The fracture risk has not been accurately evaluated, and the limited data on management indicate that hormone replacement therapy is effective and safe, whereas bisphosphonates have not been proven effective. Primary sclerosing cholangitis is rare and, consequently, few data are available. Males are predominantly affected. Concomitant inflammatory bowel disease and glucocorticoid therapy are the main causes of bone loss in primary sclerosing cholangitis.
