Higher Indocyanine Green Retention Is Associated with Improved Prognosis in Patients with Hepatocellular Carcinoma Treated with Transcatheter Arterial Chemoembolization.

PURPOSE: To test indocyanine green retention rate at 15 minutes (ICG-R15) as a prognostic biomarker in patients with hepatocellular carcinoma (HCC) treated with transcatheter arterial chemoembolization (TACE) therapy. MATERIALS AND METHODS: This retrospective cohort study was performed on the data of 278 consecutive patients with HCC treated with TACE after ICG-R15 testing at a single university hospital. Cox proportional hazard model analysis was performed to identify independent prognostic factors. After adjusting for age, sex, stage of HCC, albumin-bilirubin score, etiologies, and baseline year by propensity score matching, the prognostic impact of higher ICG-R15 was evaluated using the Kaplan-Meier curve. RESULTS: Univariate and multivariate analyses identified higher ICG-R15 as a positive prognostic factor for overall survival. Propensity score matching generated two 77-patient cohorts: ICG-R15 <20% group and ICG-R15 >20% group. The overall survival of the ICG-R15 >20% group was significantly better than that of the ICG-R15 <20% group. CONCLUSIONS: Higher ICG-R15 acted as a positive long-term prognostic factor in patients with HCC treated with TACE.

MicroRNAs and Nonalcoholic Steatohepatitis: A Review.

Non-alcoholic fatty liver disease (NAFLD) is a clinicopathologic syndrome caused by fat deposition in hepatocytes. Patients with nonalcoholic steatohepatitis (NASH), an advanced form of NAFLD with severe fibrosis, are at high risk for liver-related complications, including hepatocellular carcinoma (HCC). However, the mechanism of progression from simple fat deposition to NASH is complex, and previous reports have linked NAFLD to gut microbiota, bile acids, immunity, adipokines, oxidative stress, and genetic or epigenetic factors. NASH-related liver injury involves multiple cell types, and intercellular signaling is thought to be mediated by extracellular vesicles. MicroRNAs (miRNAs) are short, noncoding RNAs that play important roles as post-transcriptional regulators of gene expression and have been implicated in the pathogenesis of various diseases. Recently, many reports have implicated microRNAs in the pathogenesis of NALFD/NASH, suggesting that exosomal miRNAs are potential non-invasive and sensitive biomarkers and that the microRNAs involved in the mechanism of the progression of NASH may be potential therapeutic target molecules. We are interested in which miRNAs are involved in the pathogenesis of NASH and which are potential target molecules for therapy. We summarize targeted miRNAs associated with the etiology and progression of NASH and discuss each miRNA in terms of its pathophysiology, potential therapeutic applications, and efficacy as a NASH biomarker.

Influence of gender on diaphragm thickness using a method for determining intima media thickness in healthy young adults.

BACKGROUND: To clarify the differences in diaphragm thickness between male and female participants in healthy young adults with ultrasonography using the mean intima media thickness (IMT) method and to investigate the relationship between diaphragm thickness and respiratory pressure. METHODS: Twenty-nine healthy individuals (16 females and 13 males) participated in the study. Diaphragm thickness was measured at total lung capacity (TLC) and at functional residual capacity (FRC) in each participant. We measured the diaphragm thickness using a method for mean intima media thickness. Moreover, change ratio of diaphragm thickness was calculated with the diaphragm thickness at TLC and FRC. RESULTS: Mean diaphragm thicknesses at FRC in males were significantly narrower than those in females (p < 0.001). The change ratio of diaphragm thickness was significantly augmented in males compared with that in females (p < 0.001). There was a positive correlation between the change ratio of diaphragm thickness and pulmonary function data and respiratory muscle strength in healthy young adults. CONCLUSIONS: The change ratio of diaphragm thickness using the IMT method can be accurately performed with a high degree of reproducibility by clinical laboratory technicians and may be a useful indicator for evaluating diaphragm muscle strength.

Antitumor Effect of Regorafenib on MicroRNA Expression in Hepatocellular Carcinoma Cell Lines.

Hepatocellular carcinoma (HCC) is the most common primary malignancy of the liver and is one of the leading causes of cancer-related deaths worldwide. Regorafenib, a multi-kinase inhibitor, is used as a second-line treatment for advanced HCC. Here, we aimed to investigate the mechanism of the antitumor effect of regorafenib on HCC and evaluate altered microRNA (miRNA) expression. Cell proliferation was examined in six HCC cell lines (HuH-7, HepG2, HLF, PLC/PRF/5, Hep3B, and Li-7) using the Cell Counting Kit-8 assay. Xenografted mouse models were used to assess the effects of regorafenib in vivo. Cell cycle analysis, western blotting analysis, and miRNA expression analysis were performed to identify the antitumor inhibitory potential of regorafenib on HCC cells. Regorafenib suppressed proliferation in HuH-7 cell and induced G0/G1 cell cycle arrest and cyclin D1 downregulation in regorafenib-sensitive cells. During miRNA analysis, miRNA molecules associated with the antitumor effect of regorafenib were found. Regorafenib suppresses cell proliferation and tumor growth in HCC by decreasing cyclin D1 via alterations in intracellular and exosomal miRNAs in HCC.

Identification of microRNA associated with the elimination of hepatitis C virus genotype 1b by direct-acting antiviral therapies.

BACKGROUND AND AIM: Direct-acting antiviral (DAA) therapies have been proven to be highly effective for the eradication of hepatitis C virus (HCV) without resistance-associated substitutions (RASs). However, even in cases with no detected RASs, treatment sometimes fails, suggestive of the existence of some host-related factors involved in HCV eradication by DAAs. To explore such factors, we analyzed the serum microRNAs (miRNAs) of patients who received DAA treatment. METHODS: The serum miRNA expression levels of 39 patients with chronic HCV infection without any detectable RASs, who achieved sustained virological response with asunaprevir/daclatasvir or grazoprevir/elbasvir therapy, were investigated cyclopedically, using oligonucleotide microarrays. The effects of specific miRNAs on the replication of HCV were measured in the HCV genomic replicon containing Huh-7 hepatoma cells. RESULTS: Along with the disappearance of HCV, the expression quantiles of 16 miRNAs in the asunaprevir/daclatasvir group and 18 miRNAs in the grazoprevir/elbasvir group showed a tendency to increase or decrease. Among these molecules, adjustments for multiple testing yielded a significant differential expression at a false discovery rate of less than 5% for only one molecule, hsa-miR-762. Its expression quantile increased after HCV exclusion in all patients who had achieved sustained virological response. Quantitative polymerase chain reaction analysis validated a significant increase in the serum hsa-miR-762 after disappearance of HCV. On the contrary, hsa-miR-762 was decreased in the relapse and breakthrough of HCV in DAA failures. Transfection of hsa-miR-762 into cultured HCV-infected hepatocytes significantly decreased HCV-RNA replication. CONCLUSION: These data suggest that hsa-miR-762 is one of the host factors participating in HCV exclusion by DAA therapy.

Clinical impact of antibodies to Sp100 on a bacterial infection in patients with primary biliary cholangitis.

BACKGROUND: A specific antinuclear antibody for primary biliary cholangitis (PBC) is anti-Sp100, which was recognized as a serological marker of concurrent urinary tract infection. We sought to determine the clinical characteristics of PBC patients who had anti-Sp100. PATIENTS AND METHODS: Fifty-one patients with PBC and 10 healthy controls (HCs) were enrolled. Anti-Sp100 were determined with an ELISA method. Lipopolysaccharide-binding protein (LBP) was measured as a serological hallmark for bacterial infection. The correlations of anti-Sp100 with demographic, laboratory, and pathological parameters were investigated. RESULTS: Six of the 51 (11.8%) PBC patients had anti-Sp100, whereas none of the HCs did. There was no significant difference in the frequency of antimitochondrial antibodies (AMAs) between PBC patients with and without anti-Sp100 (67% vs. 82%, p = 0.5839). Biochemical and immunological parameters were not associated with the emergence of anti-Sp100 in these patients. The clinical stage by Scheuer classification was not correlated with the existence of anti-Sp100. No significant difference in the serum LBP levels was found between PBC patients with and without anti-Sp-100, although serum LBP levels were significantly higher in PBC patients with anti-Sp100 than in HCs (8.30 ± 2.24 ng/ml, vs. 5.12 ± 2.48 ng/ml, p = 0.0022). The frequency of granuloma formation was higher in the liver specimens of PBC patients with anti-Sp100 than in those without anti-Sp100 (67% vs 29%, p = 0.0710). CONCLUSION: anti-Sp100 does not become a complementary serological marker for PBC in AMA-negative patients. A bacterial infection may trigger the production of anti-Sp100. Another factor is required to initiate the autoantibody production.

Role of microRNA-210-3p in hepatitis B virus-related hepatocellular carcinoma.

Hepatitis B virus (HBV)-related hepatocarcinogenesis is not necessarily associated with the liver fibrotic stage and is occasionally seen at early fibrotic stages. MicroRNAs (miRNAs) are essentially 18- to 22-nucleotide-long endogenous noncoding RNAs. Aberrant miRNA expression is a common feature of various human cancers. The aberrant expression of specific miRNAs has been shown in hepatocellular carcinoma (HCC) tissue compared with nontumor tissue. Thus, we examined targetable miRNAs as a potential new biomarker related to the high risk of HBV-related hepatocarcinogenesis, toward the prevention of cancer-related deaths. HCC tissue samples from 29 patients who underwent hepatectomy at our hospital in 2002-2013 were obtained. We extracted the total RNA and analyzed it by microRNA array, real-time RT-PCR, and three comparisons: 1) HBV-related HCC and adjacent nontumor tissue, 2) HCV-related HCC and adjacent nontumor tissue, and 3) non-HBV-, non-HCV-related HCC and adjacent nontumor tissue. We also performed a functional analysis of miRNAs specific for HBV-related HCC by using HBV-positive HCC cell lines. MiR-210-3p expression was significantly increased only in the HBV-related HCC tissue samples. MiR-210-3p expression was upregulated, and the levels of its target genes were reduced in the HBV-positive HCC cells. The inhibition of miR-210-3p enhanced its target gene expression in the HBV-positive HCC cells. In addition, miR-210-3p regulated the HBx expression in HBV-infected Huh7/NTCP cells. The enhanced expression of miR-210-3p was detected specifically in HBV-related HCC and regulated various target genes, including HBx in the HBV-positive HCC cells. MiR-210-3p might, thus, be a new biomarker for the risk of HBV-related HCC.NEW & NOTEWORTHY Our present study demonstrated that miR-210-3p is the only microRNA with enhanced expression in HBV-related HCC, and the enhanced expression of miR-210-3p upregulates HBx expression. Therefore, miR-210-3p might be a pivotal biomarker of HBV-related hepatocarcinogenesis, and the inhibition of miR-210-3p could prevent inducing hepatocarcinogenesis related to HBV infection.

Genome-wide association studies identify PRKCB as a novel genetic susceptibility locus for primary biliary cholangitis in the Japanese population.

A previous genome-wide association study (GWAS) performed in 963 Japanese individuals (487 primary biliary cholangitis [PBC] cases and 476 healthy controls) identified TNFSF15 (rs4979462) and POU2AF1 (rs4938534) as strong susceptibility loci for PBC. In this study, we performed GWAS in additional 1,923 Japanese individuals (894 PBC cases and 1,029 healthy controls), and combined the results with the previous data. This GWAS, together with a subsequent replication study in an independent set of 7,024 Japanese individuals (512 PBC cases and 6,512 healthy controls), identified PRKCB (rs7404928) as a novel susceptibility locus for PBC (odds ratio [OR] = 1.26, P = 4.13 × 10-9). Furthermore, a primary functional variant of PRKCB (rs35015313) was identified by genotype imputation using a phased panel of 1,070 Japanese individuals from a prospective, general population cohort study and subsequent in vitro functional analyses. These results may lead to improved understanding of the disease pathways involved in PBC, forming a basis for prevention of PBC and development of novel therapeutics.

Albumin-bilirubin score indicates liver fibrosis staging and prognosis in patients with chronic hepatitis C.

AIM: Albumin-bilirubin (ALBI) grade was investigated to predict prognosis of patients with cirrhosis. It was defined using the ALBI score calculated based on serum total bilirubin and albumin, which represent liver function. The diagnostic accuracy for liver fibrosis staging in patients with chronic hepatitis using the ALBI score has not been investigated well. This study aimed to evaluate the diagnostic abilities of the ALBI score for liver fibrosis staging in chronic hepatitis and cirrhosis in Japanese patients with hepatitis C virus (HCV) infection. METHODS: Japanese patients with HCV infection who underwent liver biopsy examinations were enrolled in a retrospective study. Fibrosis staging and activity grading were assessed using the modified METAVIR score. The ALBI score was calculated according to the following equation: Log10 total bilirubin (µmol/L) × 0.66 + albumin (g/L) × (-0.085). RESULTS: A total of 382 patients were enrolled in this study. The ALBI score differentiated fibrosis stage 4 from 3 and stage 3 from 2 (P < 0.05). When an ALBI score of -2.125 was adopted as a cut-off value, the sensitivity and specificity were 73.2% and 87.1%, respectively, with a positive likelihood ratio of 5.67 to differentiate stage 4 from stages 1-3. Kaplan-Meier analysis showed that smaller ALBI scores at baseline correlated with better hepatocellular carcinoma (HCC)-free and overall survival (P < 0.05). CONCLUSIONS: The ALBI score indicates liver fibrosis staging in Japanese patients with HCV infection. Furthermore, smaller ALBI scores predict better HCC-free survival and overall survival. The ALBI score has the potential to expand its application from cirrhosis to chronic hepatitis.

Galectin-9 Induces Mitochondria-Mediated Apoptosis of Esophageal Cancer In Vitro and In Vivo in a Xenograft Mouse Model.

Galectin-9 (Gal-9) enhances tumor immunity mediated by T cells, macrophages, and dendritic cells. Its expression level in various cancers correlates with prognosis. Furthermore, Gal-9 directly induces apoptosis in various cancers; however, its mechanism of action and bioactivity has not been clarified. We evaluated Gal-9 antitumor effect against esophageal squamous cell carcinoma (ESCC) to analyze the dynamics of apoptosis-related molecules, elucidate its mechanism of action, and identify relevant changes in miRNA expressions. KYSE-150 and KYSE-180 cells were treated with Gal-9 and their proliferation was evaluated. Gal-9 inhibited cell proliferation in a concentration-dependent manner. The xenograft mouse model established with KYSE-150 cells was administered with Gal-9 and significant suppression in the tumor growth observed. Gal-9 treatment of KYSE-150 cells increased the number of Annexin V-positive cells, activation of caspase-3, and collapse of mitochondrial potential, indicating apoptosis induction. c-Jun NH2-terminal kinase (JNK) and p38 mitogen-activated protein kinase (p38) phosphorylation were activated and could be involved in apoptosis. Therefore, Gal-9 induces mitochondria-mediated apoptosis of ESCC and inhibits cell proliferation in vitro and in vivo with JNK and p38 activation.

Correlation between serum galectin-9 levels and liver fibrosis.

BACKGROUND AND AIM: Chronic liver diseases progress from chronic inflammation to fibrosis to tumorigenesis. Galectin-9, a ß-galactoside-specific animal lectin, is indicated to contribute to all three steps of progression. The aim of this study was to determine which of the three steps was most dominant in elevating the serum galectin-9 concentration and to test the possibility of galectin-9 as a serum biomarker. METHODS: Japanese patients with chronic hepatitis, liver cirrhosis, hepatocellular carcinoma (HCC), non-alcoholic fatty liver disease, or alcoholic liver disease who provided informed consent were enrolled in this study. Serum galectin-9 levels were measured using a sandwich ELISA. Multiple regression analyses were performed using ezr to identify factors that determined serum galectin-9 concentration. RESULTS: One hundred one patients with 50 of chronic hepatitis and 51 of liver cirrhosis were enrolled; the cohort included 45 cases of hepatitis C virus infection, 13 cases of hepatitis B virus infection, and 46 cases with HCC-related complications. The median serum galectin-9 concentration was 77.54 pg/mL (interquartile range: 18.89-241.9 pg/mL). Multiple linear regression analyses proved Fibrosis-4 index and aspartate aminotransferase to platelet ratio index, indexes of liver fibrosis, were able to predict the serum galectin-9 levels with statistical significance. A multiple logistic regression analysis determined 10 pg/mL increase in the serum galectin-9 concentration presented an odds ratio of 3.90 for liver fibrosis progression. CONCLUSIONS: The serum galectin-9 concentration represents a potential biomarker of liver fibrosis in patients with chronic liver diseases, regardless of chronic inflammation or the presence of HCC complications. Furthermore, higher serum galectin-9 levels are a predictor for liver fibrosis progression.

Serum miRNAs Predicting Sustained HBs Antigen Reduction 48 Weeks after Pegylated Interferon Therapy in HBe Antigen-Negative Patients.

The therapeutic goal for hepatitis B virus (HBV) infection is HBs antigen (HBsAg) seroclearance, which is achieved through 48-week pegylated interferon (Peg-IFN) therapy. This study aimed to identify predictive biomarkers for sustained HBsAg reduction by analyzing serum microRNAs. Twenty-two consecutive chronic HBV infection patients negative for HBe antigen (HBeAg) with HBV-DNA levels <5 log copies/mL, alanine aminotransferase (ALT) <100 U/L, and compensated liver functions, were enrolled. The patients were subcutaneously injected with Peg-IFNα-2a weekly for 48 weeks (treatment period), followed by the 48-week observation period. HBsAg 1-log drop relative to baseline levels recorded at the end of the observation period was considered effective. Sera were obtained at weeks 0 and 24 during the treatment period analyzed for microRNAs. The microRNA (miRNA) antiviral activity was evaluated in vitro using Huh7/sodium taurocholate cotransporting polypeptide (NTCP) cells. As a result, six patients achieved the HBsAg 1-log drop after the observation periods. Comparison of serum microRNA levels demonstrated that high miR-6126 levels at week 24 predicted HBsAg 1-log drop. Furthermore, miR-6126 reduced HBsAg in culture medium supernatants and intracellular HBV-DNA quantities in Huh7/NTCP cells. In conclusion, high serum miR-6126 levels during Peg-IFN therapy predicted the HBsAg 1-log drop 48 weeks after the completion of therapy. In vitro assays revealed that miR-6126 was able to suppress HBsAg production and HBV replication.

Clinical efficacy of free androgen index, a surrogate hallmark of circulating free testosterone level, in male patients with HCV-related chronic liver disease.

The role of free testosterone, that not bound to sex hormone-binding globulin, in male patients with HCV infection remains uncertain. We investigated whether free testosterone is involved in the progression to hepatic fibrosis/steatosis or insulin resistance in male patients with HCV-related chronic liver disease or not. Free androgen indices, which reflect circulating free testosterone levels, were calculated as 100 × total testosterone levels/sex hormone-binding globulin levels in 30 male patients with HCV-related chronic liver disease. Degrees of hepatic fibrosis and steatosis were evaluated by the New Inuyama Classification and the classification proposed by Brunt and colleagues, respectively. Insulin resistance was estimated by HOMA-IR values. Serum total testosterone levels were independent of hepatic fibrosis staging in the enrolled patients. However, circulating sex hormone-binding globulin levels were significantly increased in proportion to the severity of hepatic fibrosis. Therefore, free androgen indices were inversely correlated with the severity of hepatic fibrosis. Moreover, free androgen indices were inversely correlated with the grades of hepatic steatosis and HOMA-IR values in those patients. Our data suggest that lower circulating free testosterone levels may be recognized as the risk factor for more advanced hepatic fibrosis, steatosis and/or higher insulin resistance in male patients with HCV-related chronic liver disease.

Cancer Therapy Due to Apoptosis: Galectin-9.

Dysregulation of apoptosis is a major hallmark in cancer biology that might equip tumors with a higher malignant potential and chemoresistance. The anti-cancer activities of lectin, defined as a carbohydrate-binding protein that is not an enzyme or antibody, have been investigated for over a century. Recently, galectin-9, which has two distinct carbohydrate recognition domains connected by a linker peptide, was noted to induce apoptosis in thymocytes and immune cells. The apoptosis of these cells contributes to the development and regulation of acquired immunity. Furthermore, human recombinant galectin-9, hG9NC (null), which lacks an entire region of the linker peptide, was designed to resist proteolysis. The hG9NC (null) has demonstrated anti-cancer activities, including inducing apoptosis in hematological, dermatological and gastrointestinal malignancies. In this review, the molecular characteristics, history and apoptosis-inducing potential of galectin-9 are described.

Diagnostic Dilemma in the Detection of Antibodies to Filamentous Actin.

BACKGROUND: Antibodies to filamentous-actin (anti-F-actin) were identified as the serological hallmark of type 1 autoimmune hepatitis (AIH). However, the standardized assay for the autoantibody has not yet been established. The purposes of this study were to verify the sensitivity and specificity for anti-F-actin by different assays and to investigate the benefits of anti-F-actin. METHODS: Twenty-two patients with type 1 AIH, 8 patients with autoimmune hepatitis/primary biliary cirrhosis overlap syndrome (AIH/PBC), and 18 patients with HCV related chronic liver disease (CLD-C) were enrolled in this study. Smooth muscle antibodies (SMAs) were assessed by an indirect immunofluorescent (HF) assay. Anti-F-actin was determined by an IIF method and an enzyme-linked immunosorbent assay (ELISA) method. Seropositivity for anti-F-actin was defined as positive in both methods. RESULTS: SMAs were present in the sera of 11 of 22 patients with AIH, 2 of 8 patients with AIH/PBC, and 3 of 18 patients with CLD-C. Ten AIH patients, 2 AIH/PBC patients, and no CLD-C patients were seropositive for anti-F-actin by the IIF method, while 13 AIH patients, 3 AIH/PBC patients, and no CLD-C patients were positive by the ELISA method. The prevalence of anti-F-actin in AIH, AIH/PBC, and CLD-C were estimated as 10 of 22 (48%), 1 of 8 (13%), and 0 of 26 (0%), respectively. Three AIH patients who showed a discrepancy in the anti-F-actin status were seropositive in ELISA, but seronegative in IIF. However, none of the AIH patients were seronegative in ELISA, but seropositive in IIF. The sera of 10 of 11 AIH patients with SMAs reacted with F-actin, while no sera of AIH patients without SMAs were directed against F-actin at all. AIH patients with anti-F-actin tended to have higher relapse rates during tapering of corticosteroid treatment. However, the declines in titers of anti-F-actin did not reflect the attenuation of the disease activity by the treatment with corticosteroids. CONCLUSIONS: SMAs in the sera of AIH patients predominantly recognized filamentous actin, while SMAs in the sera of CLD-C patients did not. Anti-F-actin by IIF was superior in the specificity to those by ELISA. AIH patients seropositive for anti-F-actin may predict the relapse.

Association between left ventricular hypertrophy and changes in arterial stiffness during hypertensive treatment.

Cardio-ankle vascular index (CAVI) has been demonstrated as a parameter of arterial stiffness, which antihypertensive therapy may improve. However, little information is available about the factors affecting changes in arterial stiffness assessed by CAVI during antihypertensive therapy. We performed a study to examine the factors affecting changes in arterial stiffness assessed by CAVI during antihypertensive therapy. Eighty treated hypertensive patients (71 ± 10 years) were divided into two groups: 50 patients showing a decrease in CAVI (Group 1) and 30 patients showing an increase (Group 2) during observation (24 ± 11 months) of antihypertensive therapy. The groups did not differ in the rates of use of angiotensin II receptor blockers or calcium channel blockers. Age (Group 1: 67 ± 11 versus Group 2: 74 ± 8 years), left ventricular mass index (LVMI) (Group 1: 103 ± 19 versus Group 2: 120 ± 24 g/m(2)) and systolic blood pressure (Group 1: 133 ± 17 versus Group 2: 144 ± 23 mm Hg) at the start of observation were significantly higher in Group 2 than in Group 1 (p = 0.003, p = 0.001 and p = 0.027, respectively). The changes in CAVI during observation were correlated only with LVMI (r = 0.289, p = 0.009) at the start of observation for all 80 patients. It may be difficult to improve arterial stiffness assessed by CAVI during antihypertensive therapy in hypertensive patients with left ventricular hypertrophy.

A case of acute autoimmune hepatitis presenting after incomplete-type CREST syndrome and chronic thyroiditis.

A 55-year-old woman was admitted to our hospital with acute hepatitis of unknown origin. She had a history of incomplete-type CREST (calcinosis, Raynaud phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia) syndrome and chronic thyroiditis approximately 10 years earlier. Although she achieved spontaneous remission without treatment, she was re-admitted 18 months later due to recurrent liver dysfunction. Liver biopsy was performed as we strongly suspected autoimmune hepatitis despite her normal serum immunoglobulin G level. Liver biopsy findings were histologically compatible with autoimmune hepatitis, and administering prednisolone (30 mg/day) led to a prompt recovery of her liver dysfunction. No relapse occurred during the tapering of prednisolone to a maintenance dose of 5 mg/day. Here we report a rare case of autoimmune hepatitis in a patient with a history of incomplete-type CREST syndrome and chronic thyroiditis.

Current Trends on the Involvement of Zinc, Copper, and Selenium in the Process of Hepatocarcinogenesis.

Numerous nutritional factors increase the risk of hepatocellular carcinoma (HCC) development. The dysregulation of zinc, copper, and selenium homeostasis is associated with the occurrence of HCC. The impairment of the homeostasis of these essential trace elements results in oxidative stress, DNA damage, cell cycle progression, and angiogenesis, finally leading to hepatocarcinogenesis. These essential trace elements can affect the microenvironment in HCC. The carrier proteins for zinc and copper and selenium-containing enzymes play important roles in the prevention or progression of HCC. These trace elements enhance or alleviate the chemosensitivity of anticancer agents in patients with HCC. The zinc, copper, or selenium may affect the homeostasis of other trace elements with each other. Novel types of cell death including ferropotosis and cupropotosis are also associated with hepatocarcinogenesis. Therapeutic strategies for HCC that target these carrier proteins for zinc and copper or selenium-containing enzymes have been developed in in vitro and in vivo studies. The use of zinc-, copper- or selenium-nanoparticles has been considered as novel therapeutic agents for HCC. These results indicate that zinc, copper, and selenium may become promising therapeutic targets in patients with HCC. The clinical application of these agents is an urgent unmet requirement. This review article highlights the correlation between the dysregulation of the homeostasis of these essential trace elements and the development of HCC and summarizes the current trends on the roles of these essential trace elements in the pathogenesis of hepatocarcinogenesis.

Alcohol-related cancer morbidity and mortality are stratified using modified albumin platelet product.

Alcohol abuse is associated with several diseases, such as hepatocellular carcinoma, cirrhosis, and extrahepatic malignancies. Recently, we reported albumin platelet product (APP) and modified APP (mAPP) as novel indices of liver fibrosis staging and prognosis in patients without alcoholic liver diseases. This retrospective cohort study aimed to extend application of APP and mAPP in prognosis prediction of patients with alcoholic liver diseases. We enrolled 222 patients with alcoholic liver diseases based on their medical records. Cut-off values of APP = 4.349 and mAPP = 2.484 were adopted based on a past report. Hazard ratios of APP and mAPP were compared to those of albumin-bilirubin score and fibrosis-4 index. The primary and secondary endpoints were carcinogenesis and death, respectively. Thus, APP = 4.349 and mAPP = 2.484 significantly differentiated cancer-free survival and overall survival in univariate analysis. Hazard ratios of mAPP = 2.484 were greater than those of the albumin-bilirubin score of -2.270 and fibrosis-4 index of 3.25. Multivariate analysis revealed mAPP = 2.484 as an independent risk factor for carcinogenesis and overall death. In conclusion, mAPP is a simple index to stratify patient's risk for carcinogenesis and death.

Overall Survival of Young Patients with Hepatocellular Carcinoma in Barcelona Clinic Liver Cancer Stage B in a Retrospective Study Based on a Multicenter Cohort.

BACKGROUND: Hepatocellular carcinoma (HCC) is usually diagnosed in patients at the age of > 45 years. We aimed to determine the prognosis of patients with HCC at the age of 30-44 years compared with that of patients at a more senior age. METHODS: Based on the Sun Yat-sen University Cancer Center database, a total of 1745 patients with HCC were retrospectively enrolled and were assigned to three age groups (30-44, 45-59, and 60-70 years). The primary endpoint was overall survival. Among baseline characteristics, five variables including sex, serum albumin level, total bilirubin level, the maximum tumor diameter, and the number of tumor nodules were adjusted using propensity score matching. RESULTS: Patients aged 30-44 years presented a worse overall survival, a greater number of HCC nodules, a greater maximum tumor diameter, and higher serum alpha-fetoprotein (AFP) concentration than those aged 45-59 years in a crude analysis (p < 0.05). Using propensity score matching, the difference in overall survival between the two cohorts was canceled (p > 0.05). CONCLUSION: The prognosis of patients with HCC at age 30-44 years was equal to that of patients aged 45-59 years.
