Abstract
Cholangiocarcinoma (CCA) is a deadly complication observed in the setting of primary sclerosing cholangitis (PSC). When symptoms develop and CCA is diagnosed, it is usually at an advanced stage. Median survival is less than 12 months. Early identification of CCA leads to improved outcomes. Although diagnostic tests have excellent specificity, they are plagued by low sensitivity. No surveillance strategies have been widely agreed upon, but most societies recommend measurement of serum carbohydrate antigen 19-9 and MRCP every 6 to 12 months in patients with PSC. Advances in understanding of the genetic factors that lead to CCA are awaited.

Abstract
Histamine receptor antagonists, which can bind to specific histamine receptors on target cells, exhibit substantial therapeutic efficacy in managing a variety of histamine-mediated disorders. Notably, histamine H1 and H2 receptor antagonists have been extensively investigated and universally acknowledged as recommended treatment agents for numerous allergic diseases and acid-related disorders, respectively. Historically, the combination of H1 and H2 receptor antagonists has been considered a classic treatment strategy, demonstrating relatively superior efficacy compared with single-drug therapies in the treatment of diverse histamine-mediated diseases. The latest emerging studies have additionally suggested the underlying roles of histamine and H1R and H2R in the development of anxiety disorders, arthritic diseases, and postexercise hypotension. Nevertheless, there is still a lack of systematic reviews on the clinical efficacy of combination therapy, greatly limiting our understanding of its clinical application. Here, we present a comprehensive overview of the current knowledge and perspectives regarding the combination of H1 and H2 histamine receptor antagonists in various histamine-mediated disorders. Furthermore, we critically analyze the adverse effects and limitations associated with combination therapy while suggesting potential solutions. Our review can offer a systematic summary and promising insights into the in-depth and effective application of the combination of H1 and H2 receptor antagonists.

[PMID: 38234907 PMCID: PMC10792567 DOI: 10.1016/j.heliyon.2024.e24105] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2023] [Revised: 01/02/2024] [Accepted: 01/03/2024] [Indexed: 01/19/2024] Open
Abstract
Introduction Atypical anti-neutrophil cytoplasmic antibody (a-ANCA) is characterized by a positive fluorescence staining other than typical cytoplasmic or perinuclear ANCA. ANCA is associated with increased risk of dialysis and mortality in patients with ANCA vasculitis. However, comorbidities related to a-ANCA and whether a-ANCA exhibits an increased risk for renal failure and mortality remain unclear. This study aimed to explore the comorbidities and outcome associated with a-ANCA. Materials and methods This retrospective study enrolled 164 and 170 patients with typical ANCA and a-ANCA positivity, respectively, who visited Taichung Veterans General Hospital, Taiwan from January 2016 to March 2021. Logistic regression analysis was used to determine risk factors and the rheumatological diagnosis associated with a-ANCA. Cox proportional hazard regression and Kaplan-Meier curves were employed to identify variables associated with 5-year renal survival and mortality. Results Patients with a-ANCA had lower chance of ANCA-associated vasculitis (OR: 0.02, 95 % CI: 0.01-0.07 p < 0.001), and systemic lupus erythematosus (OR: 0.23, 95 % CI: 0.11-0.48, p < 0.001), but a higher risk of rheumatoid arthritis (OR: 2.99, 95 % CI: 1.15-7.83, p = 0.025) and ulcerative colitis (OR: 5.50, 95 % CI: 1.20-25.29, p = 0.028). Patients with a-ANCA had a better renal survival (OR: 0.14, 95 % CI: 0.08-0.24, p < 0.001) and lower mortality (OR: 0.31, 95 % CI: 0.16-0.60, p = 0.001) than patents in the typical ANCA group. The 5-year renal survival and mortality was 89.3 % and 8.8 %, respectively, in patients with a-ANCA. Conclusion Patients with a-ANCA had better renal survival and lower mortality rates compared to patients with typical ANCA. These real-world data provide evidence of the long-term outcome and shed light on avenues for the strategic management of patients with a-ANCA.

Abstract
Inflammatory Bowel Disease (IBD), a chronic nonspecific intestinal inflammatory disease, is comprised of Ulcerative Colitis (UC) and Crohn's Disease (CD). IBD is closely related to a systemic inflammatory reaction and affects the progression of many intestinal and extraintestinal diseases. As one of the representative bacteria for probiotic-assisted therapy in IBD, multiple strains of Lactobacillus have been proven to alleviate intestinal damage and strengthen the intestinal immunological barrier, epithelial cell barrier, and mucus barrier. Lactobacillus also spares no effort in the alleviation of IBD-related diseases such as Colitis-associated Colorectal cancer (CAC), Alzheimer's Disease (AD), Depression, Anxiety, Autoimmune Hepatitis (AIH), and so on via gut-brain axis and gut-liver axis. This article aims to discuss the role of Lactobacillus in IBD and IBD-related diseases, including its underlying mechanisms and related curative strategies from the present to the future.

Abstract
Liver disease is a major global health problem leading to approximately two million deaths a year. This is the consequence of a number of aetiologies, including alcohol-related, metabolic-related, viral infection, cholestatic and immune disease, leading to fibrosis and, eventually, cirrhosis. No specific registered antifibrotic therapies exist to reverse liver injury, so current treatment aims at managing the underlying factors to mitigate the development of liver disease. There are bidirectional feedback loops between the liver and the rest of the gastrointestinal tract via the portal venous and biliary systems, which are mediated by microbial metabolites, specifically short-chain fatty acids (SCFAs) and secondary bile acids. The interaction between the liver and the gastrointestinal microbiome has the potential to provide a novel therapeutic modality to mitigate the progression of liver disease and its complications. This review will outline our understanding of hepatic fibrosis, liver disease, and its connection to the microbiome, which may identify potential therapeutic targets or strategies to mitigate liver disease.

Abstract
Chronic liver disease in pregnancy is rare. Historically, many chronic liver diseases were considered contraindications to pregnancy; however, with current monitoring and treatment strategies, pregnancy may be considered in many cases. Preconception and initial antepartum consultation should focus on disease activity, medication safety, risks of pregnancy, as well as the need for additional monitoring during pregnancy. In most cases, a multidisciplinary approach is necessary to ensure optimal maternal and fetal outcomes. Despite improving outcomes, pregnancy in women with the chronic liver disease remains high risk.

Abstract
BACKGROUND Focal intrahepatic strictures (FIHS) refer to local strictures of the small and medium intrahepatic bile ducts. FIHS are easily misdiagnosed due to their rare incidence, and few studies have focused on the diagnosis and treatment approaches.
AIM To propose a new classification for FIHS in order to guide its diagnosis and treatment.
METHODS The symptoms, biochemistry results, imaging results, endoscopic examination results and initial and final diagnoses of 6 patients with FIHS admitted between January 2010 and December 2019 were retrospectively analyzed.
RESULTS The 6 patients were diagnosed with intratubular growth-type intrahepatic cholangiocarcinoma (IG-ICC), recurrent multiple hepatocellular carcinoma (rmHCC) with bile duct tumor thrombus (BDTT), adenosquamous carcinoma (ASC), hepatolithiasis, small duct primary sclerosing cholangitis (SD-PSC) and autoimmune hepatitis (AIH). The initial and final diagnoses were not consistent in 4 patients. Hepatectomy was performed in patients with IG-ICC, ASC and hepatolithiasis according to the locations of their FIHS. Patients with rmHCC with BDTT received lenvatinib/sintilimab, while patients with SD-PSC and AIH received UDCA. We proposed the following classification system for FIHS: type I: FIHS located within one segment of the liver; type II: FIHS located at the confluence of the bile ducts of one segment or two adjacent segments; type III: FIHS connected to the left or right hepatic duct; and type IV: Multiple FIHS located in both lobes of the liver.
CONCLUSION Our proposed classification system might help to guide the diagnosis and treatment of FIHS. Hepatectomy should be performed not only for malignant FIHS but also for benign strictures with severe secondary damage that cannot be improved by nonsurgical methods.

Abstract
Cholangiocarcinoma (CCA) is the most common malignancy in patients with primary sclerosing cholangitis (PSC) and carries a high rate of mortality. Although the pathogenesis of CCA in PSC is largely unknown, inflammation-driven carcinogenesis concomitant with various genetic and epigenetic abnormalities are underlying factors. The majority of CCA cases develop from a dominant stricture (DS), which is defined as a stricture with a diameter < 1.5 mm in the common bile duct or < 1.0 mm in the hepatic duct. In PSC patients presenting with an abrupt aggravation of jaundice, pain, fatigue, pruritus, weight loss, or worsening liver biochemistries, CCA should be suspected and evaluated utilizing a variety of diagnostic modalities. However, early recognition of CCA in PSC remains a major challenge. Importantly, 30-50% of CCA in PSC patients are observed within the first year following the diagnosis of PSC followed by an annual incidence ranging from 0.5 to 1.5 per 100 persons, which is nearly 10 to 1000 times higher than that in the general population. Cumulative 5-year, 10-year, and lifetime incidences are 7%, 8-11%, and 9-20%, respectively. When PSC-associated CCA is diagnosed, most tumors are unresectable, and no effective medications are available. Given the poor therapeutic outcome, the surveillance and management of PSC patients who are at an increased risk of developing CCA are of importance. Such patients include older males with large-duct PSC and possibly concurrent ulcerative colitis. Thus, more attention should be paid to patients with these clinical features, in particular within the first year after PSC diagnosis. In contrast, CCA is less frequently observed in pediatric or female PSC patients or in those with small-duct PSC or concurrent Crohn's disease. Recently, new biomarkers such as antibodies to glycoprotein 2 have been found to be associated with an increased risk of developing CCA in PSC. Herein, we review the literature on the pathogenesis, incidence, clinical features, and risk factors, with a focus on various diagnostic modalities of PSC-associated CCA.

Abstract
BACKGROUND & AIMS Primary sclerosing cholangitis (PSC) is characterized by chronic cholestasis and inflammation, which promotes cirrhosis and an increased risk of cholangiocellular carcinoma (CCA). The transcription factor Krueppel-like-factor-6 (KLF6) is a mediator of liver regeneration, steatosis, and hepatocellular carcinoma (HCC), but no data are yet available on its potential role in cholestasis. Here, we aimed to identify the impact of hepatic KLF6 expression on cholestatic liver injury and PSC and identify potential effects on farnesoid-X-receptor (FXR) signalling. METHODS Hepatocellular KLF6 expression was quantified by immunohistochemistry (IHC) in liver biopsies of PSC patients and correlated with serum parameters and clinical outcome. Liver injury was analysed in hepatocyte-specific Klf6-knockout mice following bile duct ligation (BDL). Chromatin-immunoprecipitation-assays (ChIP) and KLF6-overexpressing HepG2 cells were used to analyse the interaction of KLF6 and FXR target genes such as NR0B2. RESULTS Based on IHC, PSC patients could be subdivided into two groups showing either low (<80%) or high (>80%) hepatocellular KLF6 expression. In patients with high KLF6 expression, we observed a superior survival in Kaplan-Meier analysis. Klf6-knockout mice showed reduced hepatic necrosis following BDL when compared to controls. KLF6 suppressed NR0B2 expression in HepG2 cells mediated through binding of KLF6 to the NR0B2 promoter region. CONCLUSION Here, we show an association between KLF6 expression and the clinical course and overall survival in PSC patients. Mechanistically, we identified a direct interaction of KLF6 with the FXR target gene NR0B2.

Abstract
Background Anti-mitochondrial autoantibodies (AMA) detected by indirect immunofluorescence (IIF) on rodent tissues are the diagnostic marker of primary biliary cholangitis (PBC). However, up to 15% of patients with PBC are AMA-negative by IIF. In the effort to close the serological gap and improve the diagnostic sensitivity of PBC testing, recently, novel autoantibodies specific for PBC, such as kelch-like 12 (KLHL12, KLp epitope) and hexokinase 1 (HK1) have been described. In this study, we evaluated the autoantibody profile in a large cohort of PBC patients and in patients with other liver disease, including anti-HK1 and anti-KLp autoantibodies. Methods Sera of 194 PBC patients (126 AMA-IIF-positive and 68 AMA-IIF-negative) and 138 disease controls were tested for a panel of PBC-specific antibodies (MIT3, sp100, gp210, HK1, KLp) using a new automated particle-based multi-analyte technology (PMAT) assay on the Aptiva instrument (Inova). Results Selecting a cutoff yielding a specificity of >95% for all the markers, the sensitivity for anti-MIT3, anti-sp100, anti-gp210, anti-HK1 and anti-KLp in the PBC AMA-IIF-negative cohort was 20.6%, 16.2%, 23.5%, 22.0%, 17.6 and 13.2%, respectively. Six out of the 68 (8.8%) AMA-IIF negative sera were positive for anti-HK1 or anti-KLp alone. Using these new markers in addition to anti-MIT3, anti-sp100 and anti-gp210, the overall sensitivity in this cohort of AMA-IIF-negative patients increased from 53% to 61.8%, reducing the serological gap in AMA-negative PBC patients. Conclusions PBC antibody profiling, made possible by the new Aptiva-PMAT technology, allows recognition of a higher number of AMA-negative PBC patients than conventional immunoassays and may represent a useful tool to evaluate the prognostic significance of autoantibody association in PBC patients.

Abstract
Liver transporters play an important role in the pharmacokinetics and disposition of pharmaceuticals, environmental contaminants, and endogenous compounds. Among them, the family of ATP-Binding Cassette (ABC) transporters is the most important due to its role in the transport of endo- and xenobiotics. The ABCC sub-family is the largest one, consisting of 13 members that include the cystic fibrosis conductance regulator (CFTR/ABCC7); the sulfonylurea receptors (SUR1/ABCC8 and SUR2/ABCC9) and the multidrug resistanceassociated proteins (MRPs). The MRP-related proteins can collectively confer resistance to natural, synthetic drugs and their conjugated metabolites, including platinum-containing compounds, folate anti-metabolites, nucleoside and nucleotide analogs, among others. MRPs can be also catalogued into "long" (MRP1/ABCC1, -2/C2, -3/C3, -6/C6, and -7/C10) and "short" (MRP4/C4, -5/C5, -8/C11, -9/C12, and -10/C13) categories. While MRP2/ABCC2 is expressed in the canalicular pole of hepatocytes, all others are located in the basolateral membrane. In this review, we summarize information from studies examining the changes in expression and regulation of the basolateral hepatic transporter MPR3/ABCC3 by xenobiotics and during various pathophysiological conditions. We also focus, primarily, on the consequences of such changes in the pharmacokinetic, pharmacodynamic and/or toxicity of different drugs of clinical use transported by MRP3.

Abstract
Autoimmune liver disease (AILD) is a group of autoimmune-mediated hepatobiliary injuries, including autoimmune hepatitis, primary biliary cholangitis, and primary sclerosing cholangitis. It has been demonstrated that gene susceptibility, molecular mimicry, and abnormal immune regulation networks contribute to the occurrence and progression of AILD, while the mechanism of the related abnormal immune environment remains undetermined. It is currently believed that autoimmune diseases are mainly caused by the destruction of autoimmune tolerance mechanisms. Regulatory T cell (Treg), as a key factor to peripheral immune tolerance, may play a critical role in AILD. This article aims to elucidate the pathogenesis of AILD from the perspective of Treg cells and provide insight into the application of Treg cells in the therapy of AILD.

Abstract
Sclerosing cholangitis represents a spectrum of cholestatic liver disease characterized by inflammation, fibrosis, and stricture of the bile ducts. A 67-year-old Caucasian female with a history of breast cancer in remission, presented with jaundice and an exophytic mass at the base of the tongue. Laboratory data revealed cholestasis with alkaline phosphatase 953 U/L, total bilirubin 7.7 mg/dL, direct bilirubin 6.4 mg/dL, and gamma-glutamyltransferase 3369 U/L. Computed tomography (CT) scan showed widespread lymphadenopathy in the chest, abdomen, and pelvis concerning for lymphoma, acute pancreatitis and biliary dilation with hyperenhancement of the common bile duct wall. Diffuse intrahepatic biliary ductal dilatation and narrowing with multifocal stenosis of the proximal and distal aspects of the common bile duct was seen on magnetic resonance cholangiopancreatography (MRCP). Findings were consistent with sclerosing cholangitis. Pathology of the oral lesion revealed activin receptor-like kinase 1 (ALK1) positive anaplastic large cell lymphoma. Chemotherapy was initiated with cyclophosphamide, doxorubicin, adriamycin, vincristine, etoposide, and prednisone (CHOEP-14) regimen, which resulted in significant clinical improvement along with a remarkable decrease in the liver function tests. Non-Hodgkin's lymphoma (NHL) has only rarely been reported in the literature as a cause of secondary sclerosing cholangitis, i.e., only 0.2% to 2.0% of patients with NHL present with biliary tract obstruction. It is essential for gastroenterologists, oncologists, and radiologists to recognize sclerosing cholangitis occurring secondary to a systemic disease because early initiation of treatment can improve clinical outcome, as manifested by our case.

Abstract
Primary biliary cholangitis (PBC) is a chronic disease that is increasingly being recognized in recent years. In this study, we sought to identify noninvasive markers of the severity of cirrhosis in patients with PBC based on routinely investigated laboratory parameters.Ninety-four patients with histologically-confirmed PBC based on liver biopsy performed between January 2013 and December 2017 at the First Hospital of Jilin University were divided into 2 groups: early-stage cirrhosis (fibrosis stage F1 and F2; n = 74) and advanced-stage cirrhosis (fibrosis stage F3 and F4; n = 20).Patients with advanced-stage had significantly higher red blood cell distribution width (RDW) (15.2 vs 13.7; P = .003) and significantly lower platelet (163.35 vs 202.73; P = .032) and lymphocyte counts (1.47 vs 1.79; P = .018) as compared with patients with early-stage cirrhosis. Advanced-stage cirrhosis was associated with significantly higher RDW to platelet ratio (RPR), RDW to lymphocyte ratio (RLR), aspartate aminotransferase to platelet ratio index (APRI), and fibrosis index based on the 4 factors (FIB-4) as compared with early-stage cirrhosis. RLR showed the highest area under receiver operating characteristic curve (AUROC) (0.744). The sensitivity and specificity of RLR were 65% and 78.3%, respectively. RLR had higher AUROC than the other 3 noninvasive markers.The noninvasive markers RPR, RLR, APRI, and FIB-4 showed good diagnostic accuracy for advanced-stage cirrhosis. These markers are easily acquired by routine laboratory tests and are reproducible predictors of the severity of PBC. RLR is a novel marker that may serve as a valuable supplement to APRI and FIB-4 for predicting the severity of cirrhosis.

Abstract
Primary sclerosing cholangitis (PSC) patients are at risk of developing cholangiocarcinoma (CCA). We have shown that (1) histamine increases biliary hyperplasia through H1/H2 histamine receptors (HRs) and (2) histamine levels increase and mast cells (MCs) infiltrate during PSC and CCA. We examined the effects of chronic treatment with H1/H2HR antagonists on PSC and CCA. Wild-type and multidrug-resistant knockout (Mdr2-/- ) mice were treated by osmotic minipumps with saline, mepyramine, or ranitidine (10 mg/kg body weight/day) or a combination of mepyramine/ranitidine for 4 weeks. Liver damage was assessed by hematoxylin and eosin. We evaluated (1) H1/H2HR expression, (2) MC presence, (3) L-histidine decarboxylase/histamine axis, (4) cholangiocyte proliferation/bile duct mass, and (5) fibrosis/hepatic stellate cell activation. Nu/nu mice were implanted with Mz-ChA-1 cells into the hind flanks and treated with saline, mepyramine, or ranitidine. Tumor growth was measured, and (1) H1/H2HR expression, (2) proliferation, (3) MC activation, (4) angiogenesis, and (5) epithelial-mesenchymal transition (EMT) were evaluated. In vitro, human hepatic stellate cells were evaluated for H1HR and H2HR expression. Cultured cholangiocytes and CCA lines were treated with saline, mepyramine, or ranitidine (25 μM) before evaluating proliferation, angiogenesis, EMT, and potential signaling mechanisms. H1/H2HR and MC presence increased in human PSC and CCA. In H1/H2HR antagonist (alone or in combination)-treated Mdr2-/- mice, liver and biliary damage and fibrosis decreased compared to saline treatment. H1/H2HR antagonists decreased tumor growth, serum histamine, angiogenesis, and EMT. In vitro, H1/H2HR blockers reduced biliary proliferation, and CCA cells had decreased proliferation, angiogenesis, EMT, and migration. Conclusion: Inhibition of H1/H2HR reverses PSC-associated damage and decreases CCA growth, angiogenesis, and EMT; because PSC patients are at risk of developing CCA, using HR blockers may be therapeutic for these diseases.

Abstract
Cholangitis is a serious life-threatening situation affecting the hepatobiliary system. This review provides an update regarding the clinical and pathological features of various forms of cholangitis. A comprehensive search was performed in the PubMed, Scopus, and Web of Knowledge databases. It was found that the etiology and pathogenesis of cholangitis are heterogeneous. Cholangitis can be categorized as primary sclerosing (PSC), secondary (acute) cholangitis, and a recently characterized form, known as IgG4-associated cholangitis (IAC). Roles of genetic and acquired factors have been noted in development of various forms of cholangitis. PSC commonly follows a chronic and progressive course that may terminate in hepatobiliary neoplasms. In particular, PSC commonly has been associated with inflammatory bowel disease. Bacterial infections are known as the most common cause for AC. On the other hand, IAC has been commonly encountered along with pancreatitis. Imaging evaluation of the hepatobiliary system has emerged as a crucial tool in the management of cholangitis. Endoscopic retrograde cholangiography, magnetic resonance cholangiopancreatography and endoscopic ultrasonography comprise three of the modalities that are frequently exploited as both diagnostic and therapeutic tools. Biliary drainage procedures using these methods is necessary for controlling the progression of cholangitis. Promising results have been reported for the role of antibiotic treatment in management of AC and PSC; however, immunosuppressive drugs have also rendered clinical responses in IAC. With respect to the high rate of complications, surgical interventions in patients with cholangitis are generally restricted to those patients in whom other therapeutic approaches have failed.

Abstract
BACKGROUND Primary sclerosing cholangitis is a chronic cholestatic liver disease that is associated with both hepatobiliary and colorectal malignancies, which can result in liver cirrhosis and its complications. The optimal pharmacological treatment for patients with primary sclerosing cholangitis remains controversial. OBJECTIVES To assess the comparative benefits and harms of different pharmacological interventions in people with primary sclerosing cholangitis by performing a network meta-analysis, and to generate rankings of available pharmacological interventions according to their safety and efficacy. Given that it was not possible to assess whether potential effect modifiers were similar across comparisons, we did not perform the network meta-analysis but instead used standard Cochrane methods.When trials begin to provide an adequate description of potential effect modifiers, we will attempt to conduct network meta-analysis. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, Science Citation Index - Expanded, the WHO International Clinical Trials Registry Platform, and randomised controlled trials registers until February 2017 to identify randomised clinical trials (RCT) on pharmacological interventions for primary sclerosing cholangitis. SELECTION CRITERIA We included only RCTs, irrespective of language, blinding, or publication status, in which participants were given a diagnosis of primary sclerosing cholangitis. We excluded trials that included previously liver-transplanted participants. We considered any of various pharmacological interventions compared with one other or with placebo. We excluded trials that compared different doses of various pharmacological interventions or that reported different treatment durations, except for ursodeoxycholic acid (UDCA). As UDCA is the drug most commonly investigated for primary sclerosing cholangitis, we performed a second analysis in which we stratified the dose of UDCA. DATA COLLECTION AND ANALYSIS We calculated the odds ratio and the rate ratio with 95% confidence intervals (CIs) using both fixed-effect and random-effects models based on available-participant analysis with Review Manager. 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 22 RCTs in which 1211 participants were randomised to 13 different interventions. Most were placebo-controlled trials. Trials had few restrictions apart from an established diagnosis of primary sclerosing cholangitis, evidence of cholestasis, absence of decompensated liver disease, and absence of malignancy. However, some trials included symptomatic participants only, and others included both symptomatic and asymptomatic participants. A total of 11 RCTs (706 participants) provided data for one or more outcomes. The period of follow-up ranged from three months to three years in most trials. Only three trials reported follow-up longer than three years. Investigators found no evidence of differences in important clinical benefits such as reduction in mortality at maximal follow-up and improvement in health-related quality of life. Primary outcomes Mortality: Effect estimates: colchicine versus placebo: odds ratio 0.44, 95% CI 0.04 to 5.07, participants = 84, one trial; penicillamine versus placebo: odds ratio 1.18, 95% CI 0.39 to 3.58, participants = 70, one trial; steroids versus placebo: odds ratio 3.00, 95% CI 0.10 to 90.96, participants = 11, one trial; ursodeoxycholic acid versus placebo: odds ratio 1.51, 95% CI 0.63 to 3.63, participants = 348, two trials, I2 = 0%; vancomycin versus placebo: not estimable because no events in either group, participants = 29, one trial. Serious adverse events (proportion): Effect estimates: infliximab versus placebo: odds ratio not estimable (because of zero events in both arms), participants = 7, one trial; steroids versus placebo: odds ratio 20.00, 95% CI 0.93 to 429.90, participants = 11, one trial; vancomycin versus placebo: not estimable because no events in either group, participants = 29, one trial. Serious adverse events (number): Effect estimates: infliximab versus placebo: rate ratio 0.80, 95% CI 0.02 to 40.44, participants = 7, one trial; penicillamine versus placebo: rate ratio 13.60, 95% CI 0.78 to 237.83, participants = 70, one trial; steroids versus placebo: rate ratio 3.32, 95% CI 0.71 to 15.62, participants = 11, one trial. Adverse events (proportion): Effect estimates: steroids versus placebo: odds ratio 20.00, 95% CI 0.93 to 429.90, participants = 11, one trial; ursodeoxycholic acid versus placebo: odds ratio 1.22, 95% CI 0.68 to 2.17, participants = 198, one trial; vancomycin versus placebo: not estimable because no events in either group, participants = 29, one trial. Adverse events (number): Effect estimates: cyclosporin versus placebo: rate ratio 2.64, 95% CI 0.99 to 7.03, participants = 26, one trial; steroids versus placebo: rate ratio 3.32, 95% CI 0.71 to 15.62, participants = 11, one trial; ursodeoxycholic acid plus metronidazole versus ursodeoxycholic acid: rate ratio 2.36, 95% CI 0.98 to 5.71, participants = 71, one trial. Health-related quality of life: ursodeoxycholic acid versus placebo: mean difference 1.30, 95% CI -5.61 to 8.21, participants = 198, one trial (Short Form (SF)-36 General Health Scale). Secondary outcomes Studies provided no evidence of differences in clinical benefits such as a reduction in the requirement for liver transplantation or a reduction in the incidence proportion of cholangiocarcinoma. One small trial (29 participants) comparing vancomycin versus placebo reported no malignancies, no liver decompensation, and no liver transplantation in either group after a very short follow-up period of 12 weeks after treatment. None of the remaining trials clearly reported other clinical benefits such as decreased development of all malignancies, colorectal cancer, liver decompensation, time to liver decompensation, time to liver transplantation, or requirement for cholecystectomy to allow comparisons between different interventions. SOURCE OF FUNDING Fifteen trials reported the source of funding; three were funded by parties without vested interest in results of the trial, and 12 were funded in part or in full by drug companies. AUTHORS' CONCLUSIONS Evidence is currently insufficient to show differences in effectiveness measures such as mortality, health-related quality of life, cirrhosis, or liver transplantation between any active pharmacological intervention and no intervention. However, trials were at high risk of bias and included small numbers of participants, had short follow-up periods, and reported few clinical outcomes. An urgent need exists to identify an effective medical treatment for primary sclerosing cholangitis through well-designed RCTs with adequate follow-up that aim to identify differences in outcomes important to people with primary sclerosing cholangitis.

Abstract
Primary sclerosing cholangitis (PSC) is a rare progressive disorder leading to bile duct destruction; ∼75% of patients have comorbid inflammatory bowel disease (IBD). We undertook the largest genome-wide association study of PSC (4,796 cases and 19,955 population controls) and identified four new genome-wide significant loci. The most associated SNP at one locus affects splicing and expression of UBASH3A, with the protective allele (C) predicted to cause nonstop-mediated mRNA decay and lower expression of UBASH3A. Further analyses based on common variants suggested that the genome-wide genetic correlation (rG) between PSC and ulcerative colitis (UC) (rG = 0.29) was significantly greater than that between PSC and Crohn's disease (CD) (rG = 0.04) (P = 2.55 × 10-15). UC and CD were genetically more similar to each other (rG = 0.56) than either was to PSC (P < 1.0 × 10-15). Our study represents a substantial advance in understanding of the genetics of PSC.

Abstract
Patients with Wiskott-Aldrich syndrome (WAS) are predisposed to malignancy and autoimmunity in addition to infections. We report a male child with WAS, who had presented with recurrent pneumonia, eczema, thrombocytopenia, autoimmune hemolytic anemia, and vasculitic skin lesions. Genetic analysis revealed a classical genotype WAS 155C>T; R41X. At 2 years of follow-up, he developed persistent headache and progressive hepatomegaly. Brain imaging showed a mass in the right frontal region, which on histopathology was shown to be high-grade non-Hodgkin lymphoma. Magnetic resonance cholangiopancreatography showed features of sclerosing cholangitis. This report extends the clinical spectrum and highlights unusual manifestations of sclerosing cholangitis and intracranial lymphoma in a patient with WAS.

Abstract
BACKGROUND The overlap syndrome of primary biliary cholangitis (formerly called primary biliary cirrhosis) and primary sclerosing cholangitis is an extremely rare condition that has never been described in association with other immune-mediated diseases, including psoriatic arthritis. While treatment with anti-Tumour Necrosis Factor-alpha (TNF-α) agents has proved to be effective in inflammatory arthropathies such as psoriatic arthritis, they have been employed in only a limited number of patients with autoimmune hepatitis, and their effectiveness is unclear. CASE PRESENTATION We report the case of a 51-year-old female affected with psoriatic arthritis concomitant to overlapping primary biliary cholangitis and primary sclerosing cholangitis in whom 28 months of adalimumab treatment improved the symptoms of the inflammatory arthropathy as well as those of both cholangiopathies. CONCLUSION Our results suggest that further studies examining the therapeutic role of this particular TNF-α blocker are warranted in cholestatic autoimmune hepatitis patients, and in particular in those individuals in whom the disease is associated with inflammatory arthropathies.

Adult bile duct strictures: differentiating benign biliary stenosis from cholangiocarcinoma. Med Mol Morphol 2016; 49:189-202.

Abstract
Biliary epithelial cells preferentially respond to various insults under chronic pathological conditions leading to reactively atypical changes, hyperplasia, or the development of biliary neoplasms (such as biliary intraepithelial neoplasia, intraductal papillary neoplasm of the bile duct, and cholangiocarcinoma). Moreover, benign biliary strictures can be caused by a variety of disorders (such as IgG4-related sclerosing cholangitis, eosinophilic cholangitis, and follicular cholangitis) and often mimic malignancies, despite their benign nature. In addition, primary sclerosing cholangitis is a well-characterized precursor lesion of cholangiocarcinoma and many other chronic inflammatory disorders increase the risk of malignancies. Because of these factors and the changes in biliary epithelial cells, biliary strictures frequently pose a diagnostic challenge. Although the ability to differentiate neoplastic from non-neoplastic biliary strictures has markedly progressed with the advance in radiological modalities, brush cytology and bile duct biopsy examination remains effective. However, no single modality is adequate to diagnose benign biliary strictures because of the low sensitivity. Therefore, understanding the underlying causes by compiling the entire clinical, laboratory, and imaging data; considering the under-recognized causes; and collaborating between experts in various fields including cytopathologists with multiple approaches is necessary to achieve an accurate diagnosis.

Abstract
Lipoprotein-X, which is composed of phospholipids and non-esterified cholesterol, is an abnormal lipoprotein with a density range similar to LDL-C. The two most common ways which lipoprotein-X accumulates is from reflux of bile salts into plasma or deficiency in lecithin cholesterol acyltransferase. This is a case of severe hypercholesterolemia and liver disease in a 3- year old male that presented with pruritus, pale stool, scleral ictus, and abdominal distention. He was diagnosed with primary sclerosing cholangitis which was confirmed by liver biopsy. Our patient was treated with steroids and immunomodulator therapy which was associated with significant reduction in cholestasis and LDL-C levels. Lipoprotein-X has several properties that make it anti-atherogenic, which raises the question if treatment for hypercholesterolemia should be initiated.

Abstract
The diagnosis of primary sclerosing cholangitis (PSC) is difficult due to the lack of sensitive and specific biomarkers, as is the early diagnosis of cholangiocarcinoma (CC), a complication of PSC. The aim of this study was to identify specific serum miRNAs as diagnostic biomarkers for PSC and CC. The levels of 667 miRNAs were evaluated in 90 human serum samples (30 PSC, 30 CC and 30 control subjects) to identify disease-associated candidate miRNAs (discovery phase). The deregulated miRNAs were validated in an independent cohort of 140 samples [40 PSC, 40 CC, 20 primary biliary cirrhosis (PBC) and 40 controls]. Receiver operating characteristic (ROC) curves were established and only miRNAs with an area under the curve (AUC) > 0·70 were considered useful as biomarkers. In the discovery phase we identified the following: 21 miRNAs expressed differentially in PSC, 33 in CC and 26 in both in comparison to control subjects as well as 24 miRNAs expressed differentially between PSC and CC. After the validation phase, miR-200c was found to be expressed differentially in PSC versus controls, whereas miR-483-5p and miR-194 showed deregulated expression in CC compared with controls. We also demonstrate a difference in the expression of miR-222 and miR-483-5p in CC versus PSC. Combination of these specific miRNAs further improved the specificity and accuracy of diagnosis. This study provides a basis for the use of miRNAs as biomarkers for the diagnosis of PSC and CC.

Abstract
BACKGROUND Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease with a strong association with inflammatory bowel disease (IBD). Medical treatment for PSC is still disappointing, whereas immunomodulators and biologics have been proven to be effective in IBD. AIMS This study aimed to analyze (i) the natural history of patients with PSC with or without IBD and (ii) the long-term efficacy of biologics in patients with PSC and concomitant IBD or rheumatological disorders. PATIENTS AND METHODS This study included 92 consecutive PSC patients, 50 (54.3%) men and 42 (45.7%) women, with a mean age of 32.0±14.3 years at diagnosis and a mean follow-up duration of 103.8±86 months. Forty-nine (53.3%) patients had associated IBD (38 ulcerative colitis, 10 Crohn's disease, one indeterminate colitis). RESULTS No significant differences were found between PSC patients with and without associated IBD in terms of liver transplantation, cancer, and death rates. Cholangiocarcinoma was only identified among patients with PSC alone, whereas other cancers (hepatocellular carcinoma, colorectal, and gallbladder cancer) were found only in the group with associated IBD. Five PSC patients were treated with biologic agents: three with adalimumab and one with infliximab for IBD or for rheumatoid arthritis, and one patient with rituximab for rheumatoid arthritis. Adalimumab decreased alkaline phosphatase in two of three patients after 6 and 12 months, infliximab reduced γ-glutamyltransferase after 6 and 12 months, but liver function tests tended to deteriorate thereafter. Cholangiography changes remained stable in all patients. CONCLUSION Biologic agents may improve liver function tests in PSC patients, but may be associated with adverse events including deterioration of liver function.

Biliary strictures frequently present a diagnostic challenge during pre-operative evaluation to determine their benign or malignant nature. A variety of benign conditions, such as primary sclerosing cholangitis (PSC) and IgG4-related sclerosing cholangitis, frequently mimic malignancies. In addition, PSC and other chronic biliary diseases increase the risk of cholangiocarcinoma and so require ongoing vigilance. Although traditional methods of evaluation including imaging, detection of circulating tumour markers, and sampling by endoscopic ultrasound and endoscopic retrograde cholangiopancreatography have a high specificity, they suffer from low sensitivity. Currently, up to 20% of biliary strictures remain indeterminate after pre-operative evaluation and necessitate surgical intervention for a definitive diagnosis. The discovery of novel biomarkers, new imaging modalities and advanced endoscopic techniques suggests that a multimodality approach might lead to better diagnostic accuracy.

Primary sclerosing cholangitis associated with CREST (calcinosis, Raynaud phenomenon, oesophageal dysmotility, sclerodactyly and telangiectasia) in an elderly woman: a case report. J Med Case Rep 2015; 9:272. [PMID: 26607041 PMCID: PMC4660807 DOI: 10.1186/s13256-015-0747-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2015] [Accepted: 10/26/2015] [Indexed: 11/21/2022] Open
Abstract
Introduction CREST (calcinosis, Raynaud phenomenon, oesophageal dysmotility, sclerodactyly, and telangiectasia) syndrome comprising calcinosis cutis, Raynaud phenomenon, esophageal dysmotility, sclerodactyly and telangiectasia and primary sclerosing cholangitis are both chronic fibrotic diseases but the association between them is extremely rare. While primary sclerosing cholangitis has been associated with diffuse cutaneous scleroderma, the association with limited cutaneous scleroderma or CREST has not been previously reported in the literature. This case report illustrates the association between CREST and primary sclerosing cholangitis. Case presentation We report the case of an 84-year-old Asian woman with a long history of CREST who was admitted with abdominal pain, fatigue and progressive derangement of her liver enzymes. This was initially thought to be secondary to her bosentan therapy for pulmonary hypertension but it persisted despite bosentan being ceased. Primary sclerosing cholangitis was subsequently diagnosed on magnetic resonance cholangiopancreatography and she was referred to a hepatologist for treatment. Conclusions This case highlights the need to consider primary sclerosing cholangitis in patients with CREST who present with abdominal symptoms and deranged liver enzymes when other causes have been excluded. Relevant differential diagnoses for this presentation, which can be difficult to exclude, include immunoglobulin G4-associated cholangitis and antimitochondrial antibody negative primary biliary cirrhosis. It is of particular significance to rheumatologists and gastroenterologists but has broader relevance to all medical specialists involved in the care of patients with CREST.

Abstract
Primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC) are chronic, cholestatic diseases of the liver with common clinical manifestations. Early diagnosis and treatment of PBC slows progression and decreases the need for transplant. However, one-third of patients will progress regardless of treatment. Bilirubin <1.0 and alkaline phosphatase <2.0 x the upper limit of normal at 1 year after treatment appear to predict 10-year survival. Ursodeoxycholic acid (UDCA) is the recommended treatment for PBC, and recent studies with obeticholic acid showed promising results for UDCA non-responders. Unlike PBC, no therapy has been shown to alter the natural history of PSC. The recommended initial diagnostic test for PSC is magnetic resonance cholangiopancreatography, typically showing bile duct wall thickening, focal bile duct dilatation, and saccular dilatation of the intra- and/or extrahepatic bile ducts. Immunoglobulin 4-associated cholangitis must be excluded when considering the diagnosis of PSC, to allow for proper treatment, and monitoring of disease progression. In addition to the lack of therapy, PSC is a pre-malignant condition and close surveillance is indicated.

Abstract
BACKGROUND The liver asialoglycoprotein receptor (ASGPR) is the only organ-specific autoantigenic target in autoimmune hepatitis (AIH) patients and corresponding autoantibodies (Abs) have been suggested aiding in the serology of autoimmune liver diseases (ALD). METHODS A novel enzyme-linked immunosorbent assay (ELISA) employing purified rabbit ASGPR was used to detect ASGPR Abs in patients with ALD and controls. ASGPR Ab was determined in sera from 172 patients with AIH type 1, AIH type 2 (n=42), primary biliary cirrhosis (PBC) (n=113), cryptogenic liver disease (n=30), toxic liver disease (n=11), primary sclerosing cholangitis (PSC) (n=27), HCV infection (n=25), non-alcoholic steatohepatitis (n=43) and 100 blood donors. ASGPR Ab positivity was compared with AIH-related Abs (ANA, ASMA, Abs to LKM-1, LC-1, and SLA/LP) in patients with AIH. RESULTS Patients with AIH-1 and AIH-2 demonstrated an ASGPR Ab prevalence of 29.1% and 16.7%, respectively. ASGPR Ab positivity in patients with AIH-1 and AIH-2 was not significantly different to those in patients with PSC and HCV (p>0.05, respectively). ASGPR Ab levels in all study cohorts were significantly different with the highest medians in patients with AIH, PSC, and HCV infection (p<0.0001). ASGPR Ab can be found as only AIH-specific Ab determined by LIA and ELISA in 24.4% of AIH patients (48/197). CONCLUSIONS The novel ASGPR Ab ELISA is a specific diagnostic tool for ASGPR Ab detection in AIH. In addition to AIH, patients with PSC can demonstrate elevated ASGPR Ab amongst those with ALD suggesting a tolerance break to ASGPR in PSC.

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
IgG4-related disease (IgG4-RD) is an emerging immune-mediated disease with the capability of involving essentially any organ. The epidemiology of this disease has not been explored in detail. A majority of patients reported in the literature to date are from Japan, but the condition has been described all across the world and there is no strong evidence to suggest a predilection for Asian populations. The mean age at diagnosis is approximately 60 years and there is a decided male predominance for many clinical features, with an overall male:female ratio of 8:3. A cardinal feature of IgG4-RD is single or multiple organ swelling that often raises concern for malignancy. IgG4-RD should be suspected in patients presenting with unexplained enlargement or swelling of one or more organs. Presenting features vary substantially according to the specialty to which patients present first; in addition, the disease can be diagnosed unexpectedly in pathological specimens or identified incidentally on radiology studies. Involvement of major organs is common and IgG4-RD may lead to organ failure, particularly in the pancreas, liver and biliary tree, kidneys, thyroid gland, lungs, and aorta. The diagnosis of IgG4-RD relies on the coexistence of various clinical, laboratory and histopathological findings, although none is pathognomonic by itself.
