With the progress in detection methods and the update of diagnostic and therapeutic concepts, more and more patients with primary biliary cholangitis (PBC) have been diagnosed and treated. A high proportion of PBC patients, however, progress to liver decompensation, with an increased risk of liver transplantation and death and a significant reduction in long-term survival. These patients need early diagnosis and urgent treatment. This article discusses how to identify the PBC patients with poor prognosis early from the aspects of biochemical response, disease features, and biomarkers, and reviews the progress in related complementary therapies and new drugs including Ocaliva, Fibrates, UDCA-derived drugs, and molecular targeted drugs...

Primary biliary cholangitis (PBC) is a chronic autoimmune cholestatic disease and may progress to liver fibrosis, liver cirrhosis, decompensated cirrhosis, and even end-stage liver disease without effective treatment. The diagnosis of PBC is mainly based on the biochemical parameters indicating cholestatic hepatitis and the presence of specific autoantibody in circulation. The goals of the treatment and management of PBC are to prevent the development of end-stage liver disease, to improve related clinical symptoms, and to improve patients' quality of life...

Autoantibodies are important indicators for the diagnosis of primary biliary cholangitis (PBC). The autoantibodies in PBC patients are mainly antimitochondrial antibodies (AMAs) and antinuclear antibodies (ANAs). AMAs are one of the diagnostic indices of PBC. PBC-specific ANAs (nuclear dots or nuclear envelope, anti-sp100, and anti-gp210) have a high specificity in the diagnosis of AMA-negative PBC. This article reviews the clinical significance of these autoantibodies and analyzes some misconceptions about the clinical diagnosis of AMA-negative PBC and PBC-AIH overlap syndrome...

Primary biliary cholangitis (PBC) is an autoimmune liver disease mainly involving intrahepatic interlobular bile ducts and can progress to liver fibrosis, liver cirrhosis, and even liver failure. Ursodeoxycholic acid (UDCA) is the first-line therapeutic drug for PBC and can delay disease progression, but as high as 40% of patients have suboptimal response to UDCA. Obeticholic acid, a farnesoid X receptor agonist, has been approved by FDA in May 2016 for patients who have no response to UDCA treatment or cannot tolerate such treatment...

BACKGROUND: In primary biliary cholangitis (PBC) fatigue is a major clinical challenge of unknown etiology. By demonstrating that fatigue in PBC is associated with an impaired cognitive performance, previous studies have pointed out the possibility of brain abnormalities underlying fatigue in PBC. Whether structural brain changes are present in PBC patients with fatigue, however, is unclear. To evaluate the role of structural brain abnormalities in PBC patients severely affected from fatigue we, therefore, performed a case-control cerebral magnetic resonance imaging (cMRI) study and correlated changes of white and grey brain matter with the cognitive and attention performance...

Regulatory T cells (Tregs) play an indispensable role in the progression of primary biliary cholangitis (PBC). Although Tregs could normalize costimulation in in vivo and in vitro models, it is obscure whether and how Tregs mediate these effects in PBC. Herein we focused on the quantitative and functional characteristics of Tregs in PBC. The number and proportion of Tregs, and the production of interleukin (IL)-10 were all significantly less in the PBC patients than in the healthy controls (HCs). In addition, compared to the HCs, the costimulatory CD86 of the circulation and liver were significantly higher in the patients with PBC...

Approximately one-third of patients with primary biliary cholangitis (PBC) fail to respond to ursodeoxycholic acid (UDCA) and are at risk for progression to biliary cirrhosis and end-stage liver disease. In this paper by Pares et al., the authors evaluate the effect of long-term use of bezafibrate in patients with primary biliary cholangitis (PBC) and inadequate response to UDCA. They found that addition of bezafibrate led to normalization of serum alkaline phosphatase in half of the study subjects and major improvement in pruritus...

Autoimmunity is a consequence of both genetic and environmental factors, occurring in genetically susceptible hosts with environmental triggers. While genome-wide association studies have revealed a number of susceptible genes contributing to etiology, the environmental triggers remain poorly understood. Primary biliary cholangitis, formally known as primary biliary cirrhosis, is considered a model autoimmune disease for which our group has extensively evaluated environmental factors involved in its etiology...

In this work, a KMnO4-modified-biochar-based composite material with manganese oxide produced at 600 °C was fabricated to investigate the sorption mechanism of Cd(II) and to comprehensively evaluate the effect of the modification on biochar properties. Cd(II) adsorption mechanisms were mainly controlled by interaction with minerals, complexation with oxygen-containing functional groups, and cation-π interaction. The sorption capacity was significantly reduced after a deash treatment of biochar, almost shrunk by 3 and 3...

cGMP-dependent protein kinase from Plasmodium falciparum (PfPKG) plays a crucial role in the sexual as well as the asexual proliferation of this human malaria causing parasite. However, function and regulation of PfPKG are largely unknown. Previous studies showed that the domain organization of PfPKG significantly differs from human PKG (hPKG) and indicated a critical role of the cyclic nucleotide binding domain D (CNB D). We identified a novel mechanism, where the CNB-D controls activation and regulation of the parasite specific protein kinase...
