Abstract
Primary biliary cholangitis (PBC) is a chronic cholestatic liver disease that can progress to cirrhosis and hepatic failure if left untreated. Ursodeoxycholic acid (UDCA) was introduced as a first-line drug for PBC around 1990; it remarkably improved patient outcomes, leading to the nomenclature change of PBC in 2015, from primary biliary "cirrhosis" to primary biliary "cholangitis." Nevertheless, 20-30% of patients exhibit an incomplete response to UDCA, resulting in significantly worse outcomes compared to those with a complete response. Therefore, improving the long-term outcomes of patients with an incomplete response to UDCA has been recognized as an unmet need. In addition, patients with PBC often suffer from a variety of debilitating symptoms, such as pruritus, fatigue and sicca syndrome, which significantly impair their health-related quality of life. Thus, appropriate management of these symptoms is currently regarded as another unmet need for PBC treatment. In this review, several compounds and drugs under clinical trials that can potentially solve these unmet needs are comprehensively discussed, and future directions of treatment policy of PBC are proposed for significantly improving long-term outcome as well as health-related quality of life of patients.

Abstract
Primary biliary cholangitis (PBC) is an immune-mediated liver disease characterized by cholestasis, biliary injuries, liver fibrosis, and chronic non-suppurative cholangitis. The pathogenesis of PBC is multifactorial and involves immune dysregulation, abnormal bile metabolism, and progressive fibrosis, ultimately leading to cirrhosis and liver failure. Ursodeoxycholic acid (UDCA) and obeticholic acid (OCA) are currently used as first- and second-line treatments, respectively. However, many patients do not respond adequately to UDCA, and the long-term effects of these drugs are limited. Recent research has advanced our understanding the mechanisms of pathogenesis in PBC and greatly facilitated development of novel drugs to target mechanistic checkpoints. Animal studies and clinical trials of pipeline drugs have yielded promising results in slowing disease progression. Targeting immune mediated pathogenesis and anti-inflammatory therapies are focused on the early stage, while anti-cholestatic and anti-fibrotic therapies are emphasized in the late stage of disease, which is characterized by fibrosis and cirrhosis development. Nonetheless, it is worth noting that currently, there exists a dearth of therapeutic options that can effectively impede the progression of the disease to its terminal stages. Hence, there is an urgent need for further research aimed at investigating the underlying pathophysiology mechanisms with potential therapeutic effects. This review highlights our current knowledge of the underlying immunological and cellular mechanisms of pathogenesis in PBC. Further, we also address current mechanism-based target therapies for PBC and potential therapeutic strategies to improve the efficacy of existing treatments.

Metabolites 2023; 13:metabo13050626. [PMID: 37233667 DOI: 10.3390/metabo13050626] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Revised: 04/13/2023] [Accepted: 04/14/2023] [Indexed: 05/27/2023] Open
Abstract
Statins, the intestinal cholesterol transporter inhibitor (ezetimibe), and PCSK9 inhibitors can reduce serum LDL-C levels, leading to a significant reduction in cardiovascular events. However, these events cannot be fully prevented even when maintaining very low LDL-C levels. Hypertriglyceridemia and reduced HDL-C are known as residual risk factors for ASCVD. Hypertriglyceridemia and/or low HDL-C can be treated with fibrates, nicotinic acids, and n-3 polyunsaturated fatty acids. Fibrates were demonstrated to be PPARα agonists and can markedly lower serum TG levels, yet were reported to cause some adverse effects, including an increase in the liver enzyme and creatinine levels. Recent megatrials of fibrates have shown negative findings on the prevention of ASCVD, which were supposed to be due to their low selectivity and potency for binding to PPAR α. To overcome the off-target effects of fibrates, the concept of a selective PPARα modulator (SPPARMα) was proposed. Kowa Company, Ltd. (Tokyo, Japan), has developed pemafibrate (K-877). Compared with fenofibrate, pemafibrate showed more favorable effects on the reduction of TG and an increase in HDL-C. Fibrates worsened liver and kidney function test values, although pemafibrate showed a favorable effect on liver function test values and little effect on serum creatinine levels and eGFR. Minimal drug-drug interactions of pemafibrate with statins were observed. While most of the fibrates are mainly excreted from the kidney, pemafibrate is metabolized in the liver and excreted into the bile. It can be used safely even in patients with CKD, without a significant increase in blood concentration. In the megatrial of pemafibrate, PROMINENT, for dyslipidemic patients with type 2 diabetes, mild-to-moderate hypertriglyceridemia, and low HDL-C and LDL-C levels, the incidence of cardiovascular events did not decrease among those receiving pemafibrate compared to those receiving the placebo; however, the incidence of nonalcoholic fatty liver disease was lower. Pemafibrate may be superior to conventional fibrates and applicable to CKD patients. This current review summarizes the recent findings on pemafibrate.

Tamai H, Okamura J. Safety and efficacy of switching to pemafibrate from bezafibrate in patients with chronic liver disease. Hepatol Res 2023; 53:258-266. [PMID: 36378065 DOI: 10.1111/hepr.13859] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2022] [Revised: 11/02/2022] [Accepted: 11/09/2022] [Indexed: 11/16/2022]
Abstract
AIM Although fibrates were developed as lipid-lowering drugs, their efficacy against liver dysfunction in patients with cholestatic liver diseases, such as primary biliary cholangitis, primary sclerosing cholangitis, and fatty liver disease, has also been reported. Although fibrates act on some peroxisome proliferator-activated receptors (PPARs), pemafibrate is a novel selective PPAR-α modulator. The present study aimed to evaluate the safety and efficacy of switching from bezafibrate to pemafibrate in patients with chronic liver disease. METHODS We analyzed 58 patients with chronic liver disease who switched from bezafibrate to pemafibrate because of minor adverse effects and/or incomplete response. RESULTS This study included 41 patients with cholestatic liver disease and 17 patients with non-alcoholic fatty liver disease. Reasons for switching to pemafibrate were renal function decline in 31 patients, hemoglobin decline in 17 patients, creatine kinase (CK) elevation in 11 patients, incomplete response of liver dysfunction in 39 patients, and incomplete response of hyperlipidemia in 13 patients. After 3 months, although no significant change in CK was seen, hemoglobin and estimated glomerular filtration rate were significantly increased, and creatinine was significantly decreased. Significant decreases in hepatobiliary enzymes were seen in patients with cholestatic liver diseases, but not in patients with non-alcoholic fatty liver disease. No significant changes in serum lipids were observed. No patients discontinued pemafibrate due to adverse events. CONCLUSIONS Switching to pemafibrate could improve adverse effects due to bezafibrate, and appeared effective against liver dysfunction in cholestatic liver disease patients with incomplete response to bezafibrate.

Abstract
Primary biliary cholangitis (PBC) has a wide variation in clinical presentation and course. There is no significant correlation between these symptoms and the disease stage, although patients with more advanced stages generally have more symptoms. It is important to develop biomarkers in order to identify patients with an increased risk of complications and end-stage liver disease. This study investigated surrogate markers for risk estimation of PBC-related complications, including a study population of 77 patients with PBC who underwent liver biopsy and were measured for serum levels of macrophage activation markers, soluble CD163 (sCD163), soluble mannose receptor (sMR), and zonulin. Patients with PBC were divided into symptomatic (Group S, n = 20) and asymptomatic (Group A, n = 57) groups. The correlations of histological stages based on both Scheuer and Nakanuma classifications with the three serum markers were investigated. The Nakanuma classification involves grading for liver fibrosis and bile duct loss. The three biomarkers were assessed for their diagnostic ability to identify patients with PBC having high risk of developing complications. The predictive factors of these complications were examined as well. Group S had significantly higher serum sMR (p = 0.011) and sCD163 (p = 0.048) levels versus Group A. A composite index of sMR and sCD163 measurements had significantly better prediction performance than sCD163 alone (p = 0.012), although not when compared to sMR alone (p = 0.129). Serum sMR was an independent factor for developing complications on both univariate (Odds ratio (OR) = 30.20, 95% confidence interval (95% CI): 3.410−267.0, p = 0.00220), and multivariate (OR = 33.70, 95% CI: 3.6600−311.0, p = 0.0019) analyses. Patients with PBC having sMR of ≥56.6 had a higher incidence of clinical complications versus those with a sMR of <56.6. Serum sMR predicts the development of complications in patients with PBC. sMR plus sCD163 showed better predictive power than either marker alone, although the addition of sCD163 did not improve the predictive power of sMR. Future prospective studies are required in order to validate the findings of the present study.

Abstract
Fibrates, which are agonists of peroxisome proliferator-activated receptor alpha, have received increasing attention in the treatment of primary biliary cholangitis. Reduced alkaline phosphatase levels and improved clinical outcomes were observed in patients with primary biliary cholangitis with an inadequate response to ursodeoxycholic acid (UDCA) monotherapy4 when treated with bezafibrate or fenofibrate combined with UDCA. In contrast to obeticholic acid, which exacerbates pruritus in patients, fibrates have been shown to relieve pruritus. Clinical trial outcomes show potential for the treatment of primary biliary cholangitis by targeting peroxisome proliferator-activated receptors. It is currently agreed that primary biliary cholangitis is an autoimmune-mediated cholestatic liver disease, and peroxisome proliferator-activated receptor is a nuclear receptor that regulates the functions of multiple immune cells, thus playing an important role in regulating innate and adaptive immunity. Therefore, this review focuses on the immune disorder of primary biliary cholangitis and summarizes the regulation of hepatic immunity when peroxisome proliferator-activated receptors are targeted for treating primary biliary cholangitis.

Abstract
AIM The purpose of this study was to examine the effect of pemafibrate (PEM) in primary biliary cholangitis (PBC) patients with dyslipidemia. METHODS Patients who were diagnosed with PBC between June 2018 and December 31, 2020 were included in the study if they also had dyslipidemia and their alkaline phosphatase (ALP) or gamma-glutamyl transferase (GGT) levels remained above the normal range despite taking 600 mg/day ursodeoxycholic acid (UDCA) for at least 6 months. Patients who were treated with UDCA alone were administered PEM as an add-on (PEM-add group), and patients who were treated with UDCA and bezafibrate (BEZ) for at least 6 months were given PEM instead of BEZ (PEM-switch group). Clinical parameters were compared in all patients, and the levels of ALP, GGT, the estimated glomerular filtration rate (eGFR), and creatinine (Cr) were compared between the PEM-add and PEM-switch groups. Improvement in cholangitis was also evaluated. RESULTS In the PEM-add group, both ALP and GGT improved in 40 of 46 patients (87.0%). In the PEM-switch group, both ALP and GGT improved in 15 of 29 patients (51.7%). In the PEM-switch group, however, significant improvement was seen in eGFR and Cr. CONCLUSIONS Administration of PEM is effective in PBC patients with dyslipidemia who are refractory to UDCA monotherapy. In patients using both UDCA and BEZ, there was an advantage in switching to PEM if they had renal damage; however, improvement of ALP and GGT occurred in about 50%.

Abstract
Aim: Up to 40% of patients with primary biliary cholangitis (PBC) will have a suboptimal biochemical response to ursodeoxycholic acid (UDCA), which can be improved by the addition of fibrates. This exploratory study aims to evaluate the long-term real-life biochemical response of different fibrates, including ciprofibrate, in subjects with UDCA-unresponsive PBC. Methods: The Brazilian Cholestasis Study Group multicenter database was reviewed to assess the response rates to UDCA plus fibrates in patients with UDCA-unresponsive PBC 1 and 2 years after treatment initiation by different validated criteria. Results: In total, 27 patients (100% women, mean age 48.9 ± 9.2 years) with PBC were included. Overall response rates to fibrates by each validated criterion varied from 39 to 60% and 39–76% at 12 and 24 months after treatment combination, respectively. Combination therapy resulted in a significant decrease in ALT and ALP only after 2 years, while GGT significantly improved in the first year of treatment. Treatment response rates at 1 and 2 years appear to be comparable between ciprofibrate and bezafibrate using all available criteria. Conclusion: Our findings endorse the efficacy of fibrate add-on treatment in PBC patients with suboptimal response to UDCA. Ciprofibrate appears to be at least as effective as bezafibrate and should be assessed in large clinical trials as a possibly new, cheaper, and promising option for treatment of UDCA-unresponsive PBC patients.

Abstract
Introduction: About one-third of primary biliary cholangitis (PBC) patients do not exhibit
complete response to ursodeoxycholic acid (UDCA). Some of these patients
were reported to benefit from the combination therapy of fibrates and UDCA,
but more clinical evidence is required. In this study, we conducted a
randomized, controlled trial on the safety and efficacy of fenofibrate in
the treatment of patients with PBC. Methods: Forty-eight PBC patients with incomplete response to UDCA were enrolled and
randomly assigned to two groups (24 in the experiment group and 24 in the
control group). For the experimental group, the patients were administered
13–15 mg/kg/day UDCA in combination with 200 mg/day fenofibrate. For the
control group, the patients continued to receive UDCA at 13–15 mg/kg/day.
The patients were followed up for at least 12 months. The serum levels of
alkaline phosphatase (ALP), gamma-glutamyl transferase (γ-GT), aspartate
aminotransferase (AST), and other biochemical parameters were measured at 3,
6, and 12 months during the trial to assess patient conditions. Results: At 12 months, 20.8% of the patients in the experimental group had all three
indexes of serum ALP, γ-GT, and total bilirubin normalized, while 0% of
patients in the control group reached the primary outcome (difference,
20.8 percentage points; 95% CI, 4.6–37.0). 54.2% of the patients had normal
ALP levels in the experimental group and 4.2% in the control group
(difference, 50 percentage points; 95% CI, 28.5–71.5). The experimental
group had greater improvement of ALP (p < 0.001) and IgG
(p = 0.026) than the control group. The biochemical
indexes of the patients in the experimental group also significantly
improved during the treatment of fenofibrate. Conclusion: Addition of fenofibrate can improve biochemical indexes of PBC patients who
had an incomplete response to UDCA. Reversible elevation of serum creatine
and transaminases is observed in some patients. The trial was registered in the Chinese Clinical Trial Registry (ChiCTR) as
ChiCTR1800020160 (protocol available online: http://www.chictr.org.cn/showproj.aspx?proj=32443).

[PMID: 34697277 DOI: 10.4166/kjg.2021.092] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/12/2021] [Revised: 07/21/2021] [Accepted: 07/21/2021] [Indexed: 01/10/2023]
Abstract
Background/Aims The addition of a fibrate to ursodeoxycholic acid (UDCA) is the standard treatment for asymptomatic primary biliary cholangitis (aPBC) with an incomplete response to UDCA. Among the fibrates, bezafibrate and fenofibrate increase the serum creatinine level and reduce the estimated glomerular filtration rate (eGFR). Pemafibrate is an selective peroxisome proliferator-activated receptor alpha modulator (SPPARM-α) mainly metabolized by the liver that was recently approved to treat dyslipidemia. This study confirmed the changes in the biochemical markers after switching from fenofibrate to pemafibrate in aPBC patients. Methods This study examined the effects of switching treatment from fenofibrate to pemafibrate in 16 aPBC patients. The biological parameters of these patients were examined at the initiation of fenofibrate and after switching to pemafibrate, then at 24 and 48 weeks later, respectively. Results Among patients with aPBC treated with UDCA and fenofibrate, the ALP, GGT, and serum IgM levels decreased significantly (p<0.0001) over 48 weeks. On the other hand, serum creatinine levels increased significantly, and eGFR decreased significantly (p<0.0001). After switching to pemafibrate plus UDCA, patients with aPBC exhibited significantly lower serum creatinine levels (p=0.007) and significantly higher eGFR levels (p=0.014). Conclusions Pemafibrate has therapeutic efficacy for aPBC patients with an inadequate response to UDCA. Pemafibrate might be another option for aPBC patients given its beneficial effects on renal function, but larger, multicenter studies with a longer follow-up are needed.

Abstract
BACKGROUND The World Health Organization has set a goal of hepatitis C virus (HCV) elimination by the year 2030. However, no regions in Japan have succeeded in eradicating HCV. Micro-elimination is an approach to attain hepatitis C eradication in which national eradication goals are applied to specific populations so that viral treatment and control efforts can move forward quickly and efficiently. In order to eradicate HCV from Japan, this study aims to achieve HCV micro-elimination in the town of Nagawa. METHODS AND DESIGN The Nagawa Project is an ongoing, prospective, multiple-institution, observational study running from April 1, 2021, to March 31, 2024. All residents of Nagawa town, excluding those under 20 years of age, not consenting to the study, or unable to undergo health check-ups due to nursing care needs, will be included. If found to be HCV antibody-positive, the participant will be recommended to see a doctor in consideration of MAC-2 binding protein glycosylation isomer values. Then, the participant will undergo serum HCV RNA measurement with the real-time polymerase chain reaction by an attending physician. If the participant is HCV RNA-positive, he or she will be referred to a hepatologist for further evaluation. In the case of a definitive diagnosis of chronic hepatitis C, direct acting antiviral treatment will be initiated. Through this process, HCV will be systematically micro-eliminated from the region. DISCUSSION The Nagawa Project will reveal the prevalence of chronic HCV in addition to the HCV eradication rate in Nagawa town towards achieving HCV micro-elimination. TRIAL REGISTRATION This study is performed by Shinshu University School of Medicine and was registered as UMIN 000044114 on May 6, 2021.

Abstract
A 59-year-old woman who had been diagnosed with cirrhotic primary biliary cholangitis (PBC) 5 years earlier was admitted for severe jaundice (total bilirubin: 30.1 mg/dL). We suspected that her cirrhotic PBC had deteriorated acutely for some reason. Her general condition deteriorated quickly, and she passed away on day 18 of admission. Hepatitis E virus (HEV)-IgA antibodies were positive, and Genotype 3b HEV involvement was confirmed from a blood sample taken on admission. Histopathological findings revealed cirrhosis and submassive loss and necrosis of hepatocytes. Clinicians should consider the possibility of acute HEV infection as a trigger for acute PBC exacerbation.

Abstract
BACKGROUND AND AIM Off-label use of fibrates in patients with cholestatic liver diseases results in improved biochemical parameters and pruritus; however, their safety in this population has been a concern. This study summarizes safety data for fibrates when used for treatment of cholestatic liver diseases. METHODS A systematic review of published studies evaluating the use of fibrates for treatment of primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC) was performed. Electronic databases were searched up to December 2019 for published studies evaluating treatment outcomes associated to fibrates for these 2 diseases. RESULTS A total of 37 studies were identified, including 31 for PBC and 6 for PSC, with a total of 1107 unique patients treated with fibrates ± ursodeoxycholic acid (UDCA). Most studies evaluated fenofibrate and bezafibrate, and only 1 study evaluated pemafibrate. There were no studies evaluating gemfibrozil or clofibrate. The most commonly reported adverse events (AEs) were gastrointestinal and musculoskeletal. Elevations of aminotransferases and serum creatinine were reported more commonly in patients treated with UDCA plus fibrates versus UDCA monotherapy. CONCLUSIONS Fibrates appear to be safe and well tolerated in patients with PBC, with a low frequency of AEs. There are scarce data about the safety of these agents for treatment of PSC.

Abstract
Primary biliary cholangitis (PBC) is characterized by the presence of serum anti-mitochondrial autoantibodies (AMAs). To date, four antigens among the 2-oxo-acid dehydrogenase complex family, which commonly have lipoyl domains as an epitope, have been identified as AMA-corresponding antigens (AMA-antigens). It has recently been reported that AMAs react more strongly with certain chemically modified mimics than with the native lipoyl domains in AMA-antigens. Moreover, high concentrations of circulating immune complexes (ICs) in PBC patients have been reported. However, the existence of ICs formed by AMAs and their antigens has not been reported to date. We hypothesized that AMAs and their antigens formed ICs in PBC sera, and analyzed sera of PBC and four autoimmune diseases (Sjögren's syndrome, systemic lupus erythematosus, systemic scleroderma, and rheumatoid arthritis) using immune complexome analysis, in which ICs are separated from serum and are identified by nano-liquid chromatography-tandem mass spectrometry. To correctly assign MS/MS spectra to peptide sequences, we used a protein-search algorithm that including lipoylation and certain xenobiotic modifications. We found three AMA-antigens, the E2 subunit of the pyruvate dehydrogenase complex (PDC-E2), the E2 subunit of the 2-oxo-glutarate dehydrogenase complex (OGDC-E2) and dihydrolipoamide dehydrogenase binding protein (E3BP), by detecting peptides containing lipoylation and xenobiotic modifications from PBC sera. Although the lipoylated sites of these peptides were different from the well-known sites, abnormal lipoylation and xenobiotic modification may lead to production of AMAs and the formation ICs. Further investigation of the lipoylated sites, xenobiotic modifications, and IC formation will lead to deepen our understanding of PBC pathogenesis.

Abstract
AIM The ursodeoxycholic acid response score (URS) can predict the biochemical response to 12 months of ursodeoxycholic acid (UDCA) treatment in patients with primary biliary cholangitis (PBC). We investigated the relationship between the URS and the histopathological features before and after UDCA treatment. METHODS Patients with PBC (n = 126) were examined for the association between the probability of response (POR) to UDCA based on the URS formulas and clinicopathological features. Furthermore, 30 patients were examined for the association between the POR and pathological changes. RESULTS The POR area under the receiver operating characteristic curve (AUROC) for predicting the biochemical response to UDCA was 0.861. The PORs of stage 1 in the Nakanuma system and grade 0 in the CK7 grading in hepatocytes were significantly higher than those of stage 3 and grade 3, respectively. The AUROCs for the prediction of stage ≥2, stage ≥3 and stage 4 in the Nakanuma system at pretreatment were 0.592, 0.710 and 0.817, respectively. The AUROCs for the prediction of grade ≥1, grade ≥2 and grade 3 in the CK7 hepatocyte grading were 0.741, 0.824 and 0.970, respectively. Furthermore, the AUROC for predicting the histological stage progression after UDCA treatment in the Scheuer classification and the Nakanuma system were 0.712 and 0.799, respectively. CONCLUSIONS The URS not only predicts the biochemical response, but also reflects the Nakanuma system and the CK7 hepatocyte grading at pretreatment. This scoring system can identify an inadequate histological response to UDCA treatment in the Scheuer classification and the Nakanuma system.

Polymorphism at rs9264942 is associated with HLA-C expression and inflammatory bowel disease in the Japanese. Sci Rep 2020; 10:12424. [PMID: 32709981 PMCID: PMC7381613 DOI: 10.1038/s41598-020-69370-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2020] [Accepted: 07/08/2020] [Indexed: 11/09/2022] Open
Abstract
An expression quantitative trait locus (eQTL) single-nucleotide polymorphism (SNP) at rs9264942 was earlier associated with human leukocyte antigen (HLA)-C expression in Europeans. HLA-C has also been related to inflammatory bowel disease (IBD) risk in the Japanese. This study examined whether an eQTL SNP at rs9264942 could regulate HLA-C expression and whether four SNP haplotypes, including the eQTL SNP at rs9264942 and three SNPs at rs2270191, rs3132550, and rs6915986 of IBD risk carried in the HLA-C*12:02~B*52:01~DRB1*15:02 allele, were associated with IBD in the Japanese. HLA-C expression on CD3e+CD8a+ lymphocytes was significantly higher for the CC or CT genotype than for the TT genotype of rs9264942. The TACC haplotype of the four SNPs was associated with a strong susceptibility to ulcerative colitis (UC) but protection against Crohn’s disease (CD) as well as with disease clinical outcome. While UC protectivity was significant but CD susceptibility was not for the CGTT haplotype, the significance of UC protectivity disappeared but CD susceptibility reached significance for the CGCT haplotype. In conclusion, our findings support that the eQTL SNP at rs9264942 regulates HLA-C expression in the Japanese and suggest that the four SNPs, which are in strong linkage disequilibrium, may be surrogate marker candidates of a particular HLA haplotype, HLA-C*12:02~B*52:01~DRB1*15:02, related to IBD susceptibility and disease outcome.

Clinical utility of FibroScan as a non-invasive diagnostic test for primary biliary cholangitis. J Gastroenterol Hepatol 2020; 35:1208-1214. [PMID: 31724755 DOI: 10.1111/jgh.14929] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2019] [Revised: 10/26/2019] [Accepted: 11/09/2019] [Indexed: 12/14/2022]
Abstract
BACKGROUND AND AIM Primary biliary cholangitis (PBC) is a chronic, slowly progressive, autoimmune liver disease. Some PBC patients display disease progression regardless of medical treatment. Therefore, it is important to accurately diagnose the clinical stage of PBC. This study investigated clinical merits of vibration-controlled transient elastography using FibroScan for assessing disease stage in PBC. METHODS A total of 74 treatment-naïve PBC patients (84% female, median age: 64 years), 69 of whom having undergone histological assessment and five clinically diagnosed as at the cirrhosis stage, were enrolled for clinical comparisons of liver stiffness measurement (LSM) with other established indices. RESULTS The number of patients with Nakanuma stages 1, 2, 3, and 4 was 18, 33, 17, and 6, respectively. The median LSM values for Nakanuma stages 1, 2, 3, and 4 were 5.05, 5.90, 8.90, and 23.70 kPa, respectively, and correlated significantly with disease progression based on Nakanuma's classification (r = 0.501, P < 0.001). LSM was also significantly related to other non-invasive serological markers (Mac-2 binding protein glycosylation isomer: r = 0.606, FIB-4 index: r = 0.493, and aspartate aminotransferase-to-platelet ratio index: r = 0.577; all P < 0.001). The areas under the receiver operating characteristic curve for diagnosing Nakanuma stage ≥ 2, stage ≥ 3, and stage 4 were 0.744, 0.763, and 0.907, respectively. A combination of LSM ≥ 7.0 kPa and Mac-2 binding protein glycosylation isomer ≥ 1.00 cut-off index could predict late-stage PBC (i.e. moderate to advanced disease progression) with a sensitivity of 0.58, specificity of 0.82, and accuracy of 0.74. CONCLUSIONS Liver stiffness measurement using FibroScan provided simple, accurate, and non-invasive assessment of disease stage in PBC patients.

Prognostic significance of serum tyrosine concentration in patients with primary biliary cholangitis under ursodeoxycholic acid therapy. Hepatol Res 2020; 50:214-223. [PMID: 31652380 DOI: 10.1111/hepr.13434] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/16/2019] [Revised: 09/23/2019] [Accepted: 09/30/2019] [Indexed: 02/07/2023]
Abstract
AIM Chronic liver insufficiency is often associated with alteration in amino acid metabolism. We evaluated the prognostic value of changes in serum amino acid concentrations in patients with primary biliary cholangitis. METHODS A total of 75 primary biliary cholangitis patients who started urusodeoxycholic acid therapy were retrospectively enrolled. Baseline serum concentrations of branched-chain amino acids and tyrosine, and branched-chain amino acid-to-tyrosine ratio were determined. The hazard ratios of factors associated with liver-related events were analyzed by Cox proportional hazard analysis. RESULTS Of the 75 patients enrolled, 12 showed a decrease in serum branched-chain amino acid levels, and 15 showed an increase in serum tyrosine levels. The branched-chain amino acid-to-tyrosine ratio decreased in 16 patients. During a median 5.6-year follow up, liver-related events occurred in 11 patients. Multivariate analysis showed that high serum tyrosine levels at baseline and high alkaline phosphatase levels 48 weeks after starting urusodeoxycholic acid therapy were independent risk factors for event occurrence. From the receiver operator characteristics curve analysis, serum tyrosine concentration >110 μmol/L was identified as a cut-off value with an adjusted hazard ratio of 20.9 (95% confidence interval 4.3-101.5, P < 0.001). Kaplan-Meier analysis showed that the 5-year cumulative incidences of event occurrence in patients with high and low serum tyrosine concentration were 56.5% and 5.5%, respectively (P < 0.001). The 10-year survival probabilities also showed significant differences between patients with high and low serum tyrosine concentration (44.9% vs. 92.0%, P < 0.001). CONCLUSION Elevation of serum tyrosine concentration indicates a high risk of liver-related events in primary biliary cholangitis patients receiving urusodeoxycholic acid therapy.

Abstract
PURPOSE OF REVIEW Reduction of serum low-density lipoprotein cholesterol (LDL-C) levels by statins, ezetimibe and proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors has been shown to significantly reduce cardiovascular events risk. However, fasting and postprandial hypertriglyceridemia as well as reduced high-density lipoprotein cholesterol (HDL-C) remain as residual risk factors of atherosclerotic cardiovascular diseases (ASCVD). To treat patients with hypertriglyceridemia and/or low HDL-C, drugs such as fibrates, nicotinic acids, and n-3 polyunsaturated fatty acids have been used. However, fibrates were demonstrated to cause side effects such as liver dysfunction and increase in creatinine levels, and thus large-scale clinical trials of fibrates have shown negative results for prevention of ASCVD. The failure could be attributed to their low selectivity and potency for binding to peroxisome proliferator-activated receptor (PPAR) α. To resolve these issues, the concept of selective PPARα modulator (SPPARMα) with a superior balance of efficacy and safety has been proposed and pemafibrate (K-877) has been developed. RECENT FINDINGS Pemafibrate, one of SPPARMsα, was synthesized by Kowa Company, Ltd. for better efficiency and safety. Clinical trials in Japan have established the superiority of pemafibrate on effects on serum triglycerides (TG) reduction and HDL-C elevation as well safety. Although available fibrates showed worsening of liver and kidney function test values, pemafibrate indicated improved liver function test values and was less likely to increase serum creatinine or decrease estimated glomerular filtration rate (eGFR). Very few drug-drug interactions were observed even when used concomitantly with statins. Furthermore, pemafibrate is metabolized in the liver and excreted into the bile, while many of available fibrates are mainly excreted from the kidney. Therefore, pemafibrate can be used safely even in patients with impaired renal function since there is no significant increase in its blood concentration. A large-scale trial of pemafibrate, PROMINENT, for dyslipidemic patients with type 2 diabetes is ongoing. Pemafibrate is one of novel SPPARMsα and has superior benefit-risk balance compared to conventional fibrates and can be applicable for patients for whom the usage of existing fibrates is difficult such as those who are taking statins or patients with renal dysfunction. In the current review, all the recent data on pemafibrate will be summarized.
