OBJECTIVE: In patients with liver cirrhosis, the clinical characteristics of dynapenia, a condition in which skeletal muscle mass is maintained but muscle strength is reduced, are not yet known. This study aimed to clarify the characteristics of dynapenia and its impact on quality of life (QOL) in patients with liver cirrhosis. METHODS: We retrospectively analyzed 116 patients with cirrhosis. Based on grip strength and skeletal muscle mass measured by the bioelectrical impedance analysis method, patients were divided into four groups: normal muscle status, dynapenia, pre-sarcopenia (a condition involving only low muscle mass), and sarcopenia. The characteristics of dynapenia and its influence on QOL were examined. RESULTS: Fourteen patients had dynapenia. Liver function did not differ among the four groups. In patients with dynapenia, BMI was highest and computed tomography attenuation of skeletal muscle at the third lumbar spine vertebra was lowest among the four groups. The percentage of patients with both BMI ≥25 kg/m2 and myosteatosis was significantly higher in patients with dynapenia [9/14 (64.3%)] than in those with sarcopenia [2/23 (8.7%), P = 0.004] and pre-sarcopenia [0/18 (0%), P < 0.001] and tended to be higher than those with normal muscle status [16/61 (26.2%), P = 0.065]. The physical QOL in patients with dynapenia was as low as that in those with sarcopenia and significantly lower than that in those with normal muscle status. CONCLUSION: Cirrhotic patients with dynapenia had high BMI and myosteatosis, and impaired physical QOL.

Objective: The nuclear receptor corepressor 1 (NCOR1) and the silencing mediator of retinoic acid and thyroid hormone (SMRT, also known as NCOR2) play critical and specific roles in nuclear receptor action. NCOR1, both in vitro and in vivo specifically regulates thyroid hormone (TH) action in the context of individual organs such as the liver, and systemically in the context of the hypothalamic-pituitary-thyroid (HPT) axis. In contrast, selective deletion of SMRT in the liver or globally has shown that it plays very little role in TH signaling. However, both NCOR1 and SMRT have some overlapping roles in hepatic metabolism and lipogenesis. Here, we determine the roles of NCOR1 and SMRT in global physiologic function and find if SMRT could play a compensatory role in the regulation of TH action, globally. Methods: We used a postnatal deletion strategy to disrupt both NCOR1 and SMRT together in all tissues at 8–9 weeks of age in male and female mice. This was performed using a tamoxifen-inducible Cre recombinase (UBC-Cre-ERT2) to KO (knockout) NCOR1, SMRT, or NCOR1 and SMRT together. We used the same strategy to KO HDAC3 in male and female mice of the same age. Metabolic parameters, gene expression, and thyroid function tests were analyzed. Results: Surprisingly, adult mice that acquired NCOR1 and SMRT deletion rapidly became hypoglycemic and hypothermic and perished within ten days of deletion of both corepressors. Postnatal deletion of either NCOR1 or SMRT had no impact on mortality. NCOR1/SMRT KO mice rapidly developed hepatosteatosis and mild elevations in liver function tests. Additionally, alterations in lipogenesis, beta oxidation, along with hepatic triglyceride and glycogen levels suggested defects in hepatic metabolism. The intestinal function was intact in the NCOR1/SMRT knockout (KO) mice. The KO of HDAC3 resulted in a distinct phenotype from the NCOR1/SMRT KO mice, whereas none of the HDAC3 KO mice succumbed after tamoxifen injection. Conclusions: The KO of NCOR1 and SMRT rapidly leads to significant metabolic abnormalities that do not survive – including hypoglycemia, hypothermia, and weight loss. Hepatosteatosis rapidly developed along with alterations in hepatic metabolism suggesting a contribution to the dramatic phenotype from liver injury. Glucose production and absorption were intact in NCOR1/SMRT KO mice, demonstrating a multifactorial process leading to their demise. HDAC3 KO mice have a distinct phenotype from the NCOR1/SMRT KO mice—which implies that NCOR1/SMRT together regulate a critical pathway that is required for survival in adulthood and is separate from HDAC3.

Aim: Novel glass membrane pumping emulsification devices (GMDs) enable the formation of a high-percentage water-in-oil emulsion with homogeneous and stable droplets. Although GMDs are expected to improve therapeutic effects in transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC), clinical outcomes are not yet available. Patients and Methods: A total of 26 patients with unresectable HCC who underwent TACE using a GMD were analyzed retrospectively. Ethiodized oil was mixed with epirubicin solution using a GMD. The emulsion was injected into the tumor-feeding artery, followed by embolization. Results: The median size of HCCs was 28 (range=15-60) mm, and 15 nodules were solitary. Overall treatment effects were complete response in 18 cases (90%) and partial response in two (10%). The local recurrence rate at 6 months was 24.2%. No major complication was observed except for grade 4 elevations of liver enzymes in one case. Conclusion: TACE using a GMD is effective and safe in clinical practice.

Background: The clinical course of liver injury induced by immune checkpoint inhibitors (ICIs) varies among individuals, and there were few reports on the therapeutic effects of corticosteroids based on the patterns of liver injury. Methods: We evaluated the characteristics and clinical course of immune-related liver injury in 1214 patients treated with ICIs for advanced malignancies except for hepatocellular carcinoma between August 2014 and May 2021. Results: During the follow-up period (median, 252 days), 58 patients (4.8%) had an immune-related liver injury (≥ Grade 3). The liver-injury patterns were hepatocellular (n = 26, 44.8%), mixed (n = 11, 19.0%), or cholestatic (n = 21, 36.2%), and the median time to onset of liver injury was 39, 81, and 53 days, respectively; the hepatocellular pattern occurred earlier than the other types (p = 0.047). Corticosteroids were administered to 30 (51.7%) patients; while liver injury was improved in almost all patients with the hepatocellular pattern (n = 13/14, 92.9%), that failed to show improvement in over half of the patients with the non-hepatocellular patterns, and three patients with mixed patterns needed secondary immunosuppression with mycophenolate mofetil. Liver biopsies performed in 13 patients mainly showed lobular injury, endothelialitis, and spotty necrosis with infiltration of T cells positive for CD3 and CD8, but not CD4 or CD20. Conclusion: The incidence pattern and therapeutic response to corticosteroids in immune-related liver injury differ according to the injury type. Although corticosteroids were effective for the hepatocellular pattern, an additional strategy for refractory non-hepatocellular patterns is needed.

Introduction and objectives: Hepatitis C virus (HCV) infections in patients with hemophilia lead to the development of hepatocellular carcinoma (HCC) at a relatively younger age than that in patients without hemophilia. Although recent progress in direct-acting-antivirals has facilitated a high rate of sustained virological response (SVR), the clinical influence of HCV eradication in hemophilia patients remains unclear. This study aimed to compare the clinical outcomes of SVR against HCV in patients with and without hemophilia. Patients and methods: The study enrolled 699 patients who achieved SVR after HCV antiviral treatment. Patients were divided into two groups: 78 patients with hemophilia (H group) and 621 patients without hemophilia (NH group). We evaluated patient characteristics, clinical outcomes, and the cumulative incidence of HCC after SVR. Results: Compared with the NH group, patients in the H-group were significantly younger and had a lower hepatic fibrosis score. No difference was found in the incidence of liver-related disease or overall death between the two groups over a mean follow-up period of 7 years. Four patients in the H group and 36 patients in the NH group were diagnosed with HCC after SVR. Multivariate analysis showed that male sex, age, and cirrhosis were significant risk factors for HCC incidence. There was no significant difference in the cumulative incidence of HCC after propensity-score matching adjusting for the risk factors of HCC between the two groups. Conclusion: Hemophilia is not a significant risk factor for hepatocarcinogenesis after SVR against HCV.

Non-alcoholic steatohepatitis (NASH) occurrence has been increasing and is becoming a major cause of liver cirrhosis and liver cancer. However, effective treatments for NASH are still lacking. We examined the benefits of serum-free conditioned medium from stem cells derived from human exfoliated deciduous teeth (SHED-CM) on a murine non-alcoholic steatohepatitis (NASH) model induced by a combination of Western diet (WD) and repeated administration of low doses of carbon tetrachloride intraperitoneally, focusing on the gut-liver axis. We showed that repeated intravenous administration of SHED-CM significantly ameliorated histological liver fibrosis and inflammation in a murine NASH model. SHED-CM inhibited parenchymal cell apoptosis and reduced the activation of inflammatory macrophages. Gene expression of pro-inflammatory and pro-fibrotic mediators (such as Tnf-α, Tgf-β, and Ccl-2) in the liver was reduced in mice treated with SHED-CM. Furthermore, SHED-CM protected intestinal tight junctions and maintained intestinal barrier function, while suppressing gene expression of the receptor for endotoxin, Toll-like receptor 4, in the liver. SHED-CM promoted the recovery of Caco-2 monolayer dysfunction induced by IFN-γ and TNF-α in vitro. Our findings suggest that SHED-CM may inhibit NASH fibrosis via the gut-liver axis, in addition to its protective effect on hepatocytes and the induction of macrophages with unique anti-inflammatory phenotypes.

Objectives: In this study, we revisited the reasons for poorer prognosis after liver transplant in patients with hepatitis C virus, whose main causes of death were generally known to be recurrent disease. Materials and Methods: Between April 2003 and March 2017, among 132 patients who underwent liver transplant because of liver cirrhosis at our institution, 40 patients (30.3%) were positive for hepatis C virus. We retrospectively compared the overall survival after liver transplant in patients with and without hepatitis C virus infection. Furthermore, we investigated the causes of death in transplant recipients with hepatitis C virus infections. Results: In patients with hepatitis C virus infection, overall survival was 82.2%, 75.2%, and 50.8% at 1, 5, and 10 years, respectively, after liver transplant; these results were lower than those in patients without infection (94.5%, 87.0%, and 87.0% at 1, 5, and 10 years, respectively; P = .001). Among 40 patients with positive infection, 14 patients died after liver transplant. A main reason for death was hepatocellular carcinoma recurrence (3 patients). Surprisingly, only 1 patient died from hepatitis C virus-related complication (fibrosing cholestatic hepatitis); the remaining 10 patients died from reasons other than hepatitis C virus disease progression. Conclusions: Our results suggest that clinicians should not only be aware of hepatitis C virus recurrence but should also be aware of other unrelated complications in transplant recipients who are positive for this virus.

In brown adipose tissue, thermogenesis is suppressed by thioesterase superfamily member 1 (Them1), a long chain fatty acyl-CoA thioesterase. Them1 is highly upregulated by cold ambient temperature, where it reduces fatty acid availability and limits thermogenesis. Here, we show that Them1 regulates metabolism by undergoing conformational changes in response to β-adrenergic stimulation that alter Them1 intracellular distribution. Them1 forms metabolically active puncta near lipid droplets and mitochondria. Upon stimulation, Them1 is phosphorylated at the N-terminus, inhibiting puncta formation and activity and resulting in a diffuse intracellular localization. We show by correlative light and electron microscopy that Them1 puncta are biomolecular condensates that are inhibited by phosphorylation. Thus, Them1 forms intracellular biomolecular condensates that limit fatty acid oxidation and suppress thermogenesis. During a period of energy demand, the condensates are disrupted by phosphorylation to allow for maximal thermogenesis. The stimulus-coupled reorganization of Them1 provides fine-tuning of thermogenesis and energy expenditure.

We investigated the relationship between the fever and the disappearance or decrease of lesion contrast on contrast enhanced CT images after 2 weeks of sorafenib treatment for patients with advanced hepatocellular carcinoma (HCC). Subjects were 64 patients who began sorafenib therapy. Contrast enhanced CT images were taken at baseline and after 2 weeks of sorafenib treatment. In patients with fever, the ratio of patients demonstrating the disappearance or decrease of lesion contrast on contrast enhanced CT images was significantly higher than in those without fever (91.3% and 61.0%, respectively, p=0.010, Fisher's exact probability test). The results suggested the relationship between the fever and contrast change on contrast enhanced CT.

We performed percutaneous radio frequency ablation (RFA) therapy by two-step insertion method using VirtuTRAXTM (GE Healthcare, USA) instrument navigator. Subjects were 16 patients (23 nodules) with hepatocellular carcinoma. VirtuTRAXTM position sensor was attached to the hilt of 14-gauge outer needle. In all cases, we could perform 17- gauge Cool-tip RFA without the positional gap between the virtual tract and the actual needle which was caused by the deflection of the needle. The reasons without causing the positional gap were that the outer needle was more rigid than Cool-tip needle, and that it was inserted using initial insertion of a 21-gauge guided needle. RFA by two-step insertion method using VirtuTRAXTM is suggested to be more safe and effective than conventional RFA.

Miriplatin is a platinum complex developed to treat hepatocellular carcinoma (HCC) via administration into the hepatic artery as a sustained-release suspension in iodized oil. We retrospectively evaluated the efficacy of combination therapy with transcatheter arterial infusion chemotherapy using miriplatin and percutaneous radiofrequency ablation for HCC in 11 patients. Immediately after transcatheter arterial infusion chemotherapy using miriplatin, we performed radiofrequency ablation. The greatest long-axis and short-axis dimensions of the area coagulated after combination therapy were 42 mm (35-80 mm) and 34 mm (32-60 mm), respectively. During follow-up (median 12 months), there was no recurrence from the same subsegment. No serious adverse events were observed. These results suggested that using the combination therapy, it is possible to finish one treatment session for patient with HCC.

Clearance of HBsAg is considered the ultimate goal in the treatment for chronic hepatitis B. We analyzed clinical factors associated with HBsAg clearance during long-term nucleot(s)ide analogue treatment. By univariate analysis, HBV genotype, family history of HBV infection, previous IFN therapy, HBeAg clearance at 6 months, and undetectable HBV DNA at 6 months were significant predictive factors. By multivariate analysis, HBV genotype, previous IFN therapy, HBeAg clearance at 6 months, and undetectable HBV DNA at 6 months were independent and significant predictive factors of HBsAg clearance. We conclude that patients with genotype A have high probability of HBsAg clearance, and it seems that not only the antiviral potential of nucleot(s)ide analogue but host immune response is needed to achieve HBsAg clearance.

To further improve therapeutic effect on chronic hepatitis C, we have administered NS3 inhibitor and NS5A inhibitor together, and examined effects of early antiviral agent therapy. The subjects were five cases where interferon is ineffective (null responders). The NS5A and NS3 inhibitors are oral drugs and were daily administered for 24 weeks. Figure 1 shows time-dependent change of the number of viruses after the therapy started, and rapid decrease of viruses is recognized. Within 12 hours, HCV-RNA decreased by more than 2 log IU/ml in every patient. Two patients became negative for the virus by the 15th day after the therapy started. Furthermore, 80% of cases by the 28th day and all the cases by the 56th day became negative. The new therapy has manifested excellent early antiviral effect.

Objective The aim of this study was to evaluate the efficacy and safety of combination therapy of natural human interferon-beta and ribavirin for patients for whom prior interferon therapy was discontinued due to depression induced by interferon-alpha. Methods Inclusion criteria were as follows; 1) HCV-genotype 1b, 2) serum HCV RNA level of ≥100 KIU/mL, 3) stopping the prior interferon-alpha monotherapy or combination therapy of interferon-alpha and ribavirin due to the appearance of depression. A total of 14 were enrolled in this prospective cohort study. The treatment period of combination therapy was 48 weeks. Depression states, reflected by Beck depression inventories and Hamilton depression rating scale, were assessed during combination therapy. Nonparametric procedures were employed for the analysis of background features of the patients with sustained virological response (SVR) and without SVR. A p value of <0.05 was considered to indicate a significant difference. Results Five of 14 patients (37.5%) had SVR by the intention to treat analysis. The SVR rate in patients who showed negative HCV RNA at 12 and 24 weeks after the initiation of combination therapy was 100% (4/4) and 83.3% (5/6), respectively. All of the patients continued the combination therapy owing to disappearance of severely adverse events contained the exacerbation of depression. Combination therapy did not yield a statistical difference in Beck depression inventories and Hamilton depression rating scale. Conclusion The combination therapy of IFN-beta and ribavirin is a possible therapy selection for the patients for whom interferon therapy was discontinued due to depression induced by interferon-alpha.

Miriplatin is a novel lipophilic platinum complex developed to treat hepatocellular carcinoma (HCC). Although HCC patients frequently have coexisting severe liver cirrhosis, there is no prospective data regarding clinical toxicity of miriplatin in HCC patients with severe cirrhosis. We retrospectively evaluated the safety and efficacy of transcatheter arterial chemotherapy with miriplatin in 34 HCC patients with severe liver cirrhosis (Child-Pugh grade B). An anti-tumor effect of complete response was achieved in 8 of 34 patients and no serious adverse events were observed. These results suggested that transcatheter arterial chemotherapy with miriplatin can be used safety for HCC patients with Child-Pugh B liver cirrhosis.

骨格筋はマイオカインと総称されるペプチドの分泌を通じて、肝臓を含む全身の代謝臓器との臓器間コミュニケーションにおいて重要な役割を果たしている。近年、研究代表者はマウスモデルにおいて骨格筋における脂肪酸のβ酸化が臓器を超えて脂肪肝、インスリン抵抗性、肥満の発症に関与していること、また骨格筋が代謝状態に応じて複数のマイオカインを分泌し肝臓からの超低密度リポタンパク質(VLDL)分泌を調節していることを明らかにした。これらの知見は骨格筋の脂肪酸代謝が全身の糖代謝、脂質代謝において重要な役割を果たしていること、骨格筋がマイオカインを通じて過栄養時の脂肪肝、肥満の発症に寄与していることを示唆している。
