Coexistence of muscle atrophy and high subcutaneous adipose tissue radiodensity predicts poor prognosis in hepatocellular carcinoma. Front Nutr 2023; 10:1272728. [PMID: 37867493 PMCID: PMC10587397 DOI: 10.3389/fnut.2023.1272728] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2023] [Accepted: 09/20/2023] [Indexed: 10/24/2023] Open
Abstract
Introduction We aimed to assess the prognostic implications of muscle atrophy and high subcutaneous adipose tissue (SAT) radiodensity in patients with hepatocellular carcinoma (HCC). Methods In this retrospective study, muscle atrophy was assessed using the psoas muscle index (PMI) obtained from computed tomography. SAT radiodensity was evaluated based on radiodensity measurements. Survival and multivariate analyses were performed to identify factors associated with prognosis. The impact of muscle atrophy and high SAT radiodensity on prognosis was determined through survival analysis. Results A total of 201 patients (median age: 71 years; 76.6% male) with HCC were included. Liver cirrhosis was observed in 72.6% of patients, and the predominant Child-Pugh grade was A (77.1%). A total of 33.3% of patients exhibited muscle atrophy based on PMI values, whereas 12.9% had high SAT radiodensity. Kaplan-Meier survival analysis demonstrated that patients with muscle atrophy had significantly poorer prognosis than those without muscle atrophy. Patients with high SAT radiodensity had a significantly worse prognosis than those without it. Muscle atrophy, high SAT radiodensity, the Barcelona Clinic Liver Cancer class B, C, or D, and Child-Pugh score ≥ 6 were significantly associated with overall survival. Further classification of patients into four groups based on the presence or absence of muscle atrophy and high SAT radiodensity revealed that patients with both muscle atrophy and high SAT radiodensity had the poorest prognosis. Conclusion Muscle atrophy and high SAT radiodensity are significantly associated with poor prognosis in patients with HCC. Identifying this high-risk subgroup may facilitate the implementation of targeted interventions, including nutritional therapy and exercise, to potentially improve clinical outcomes.

Recent prevalence and characteristics of patients with hepatitis delta virus in Hokkaido, Japan. Hepatol Res 2023; 53:960-967. [PMID: 37332115 DOI: 10.1111/hepr.13936] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2023] [Revised: 05/26/2023] [Accepted: 06/12/2023] [Indexed: 06/20/2023]
Abstract
AIM Although hepatitis delta virus (HDV) coinfection with hepatitis B virus (HBV) is a global health concern, the global prevalence of HDV infections remains unknown due to insufficient data in many countries. In Japan, HDV prevalence has not been updated for over 20 years. We aimed to investigate the recent prevalence of HDV infections in Japan. METHODS We screened 1264 consecutive patients with HBV infection at Hokkaido University Hospital between 2006 and 2022. Patients' serums were preserved and subsequently tested for HDV antibody (immunoglobulin-G). Available clinical information was collected and analyzed. We compared the changes in liver fibrosis using the Fibrosis-4 (FIB-4) index between propensity-matched patients with and without the evidence of anti-HDV antibodies and corrected for baseline FIB-4 index, nucleoside/nucleotide analog treatment, alcohol intake, sex, HIV coinfection, liver cirrhosis, and age. RESULTS After excluding patients without properly stored serums and those lacking appropriate clinical information, 601 patients with HBV were included. Of these, 1.7% of patients had detectable anti-HDV antibodies. Patients with anti-HDV antibody serum positivity had a significantly higher prevalence of liver cirrhosis, significantly lower prothrombin time, and a higher prevalence of HIV coinfection than those who demonstrated serum anti-HDV antibody negativity. A propensity-matched longitudinal analysis revealed that liver fibrosis (FIB-4 index) progressed more rapidly in patients with positive results for anti-HDV antibody tests. CONCLUSIONS The recent prevalence of HDV infections in Japanese patients with HBV was 1.7% (10/601). These patients experienced rapid liver fibrosis progression, highlighting the importance of routine HDV testing.

Neutrophil gelatinase-associated lipocalin predicts the efficacy of tolvaptan for ascites in patients with liver cirrhosis. J Gastroenterol 2023; 58:656-667. [PMID: 37103575 DOI: 10.1007/s00535-023-01993-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Accepted: 04/08/2023] [Indexed: 04/28/2023]
Abstract
BACKGROUND Acute kidney injury (AKI) is associated with liver cirrhosis (LC), water retention, diuretics to treat water retention, and a poor prognosis. Urinary neutrophil gelatinase-associated lipocalin (uNGAL) reportedly predicts a poor prognosis in decompensated LC. This study investigated the usefulness of uNGAL in predicting the short- and long-term effects of tolvaptan (TVP) and the incidence of AKI post-TVP administration. METHODS Of the LC cases with water retention, 86 with available pre-treatment uNGAL were analyzed. A short-term response was defined as weight loss of ≥ 1.5 kg within the first week; a long-term response was defined as a short-term response without early recurrence. The uNGAL usefulness in predicting the short- and long-term effects of TVP and AKI incidence post-TVP administration was investigated. RESULTS Short-term effects of TVP were observed in 52 patients. Of these, 15 patients had an early recurrence. In multivariate analysis, significant short-term predictive factors were C-reactive protein (CRP) < 1.4 mg/dl, uNa/K ratio ≥ 3.51, and uNGAL < 50.2 ng/ml. Patients were classified according to these three cut-off values, with short-term response rates of 92.9%, 68.8%, 26.7%, and 0% for 0, 1, 2, and 3 points, respectively. CRP < 0.94 mg/dl and uNGAL < 50.2 ng/ml were significant factors for predicting the long-term response of TVP. The AKI incidence post-TVP was 8.1% (n = 7) and was significantly higher among those with uNGAL ≥ 38.1 ng/mL. CONCLUSION uNGAL is a useful predictor of the short- and long-term efficacy of TVP and can be useful in predicting AKI incidence post-TVP administration.

Potential Correlation between Changes in Serum FGF21 Levels and Lenvatinib-Induced Appetite Loss in Patients with Unresectable Hepatocellular Carcinoma. Cancers (Basel) 2023; 15:3257. [PMID: 37370867 DOI: 10.3390/cancers15123257] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2023] [Revised: 06/16/2023] [Accepted: 06/18/2023] [Indexed: 06/29/2023] Open
Abstract
Lenvatinib, used for unresectable hepatocellular carcinoma (HCC), causes appetite loss, but the underlying mechanisms, clinical impact, and predictive factors have been unclear. The endocrine factor FGF21 modulates appetite and is involved in cachexia. We evaluated the association between FGF21 level changes during lenvatinib treatment for unresectable HCC and appetite loss. Sixty-three eligible unresectable HCC patients who started lenvatinib treatment between 2018 and 2021 were included. We analyzed FGF21 levels at baseline; 1, 2, and 4 weeks after lenvatinib initiation, and before the onset of appetite loss. Grade ≥ 2 lenvatinib-induced appetite loss led to liver functional reserve deterioration at disease progression and a poor prognosis. Baseline characteristics and serum FGF21 levels were similar between patients with and without appetite loss. However, the serum FGF21 change rate increased significantly at 4 weeks post-lenvatinib initiation in patients with grade ≥ 2 appetite loss, as compared to those without appetite loss. Similar significant increases in the serum FGF21 level change rate were observed prior to grade ≥ 2 appetite loss onset. This suggests that changes in FGF21 levels can be used to predict patients with a greater risk of marked appetite loss and provides insights into the mechanisms underlying lenvatinib-induced appetite loss in patients with HCC.

Low Baseline CXCL9 Predicts Early Progressive Disease in Unresectable HCC with Atezolizumab Plus Bevacizumab Treatment. Liver Cancer 2023; 12:156-170. [PMID: 37325489 PMCID: PMC10267515 DOI: 10.1159/000527759] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2021] [Accepted: 10/13/2022] [Indexed: 07/30/2023] Open
Abstract
INTRODUCTION Atezolizumab plus bevacizumab treatment is highly effective in patients with unresectable hepatocellular carcinoma (HCC). However, progressive disease (PD) occurs in approximately 20% of HCC patients treated with atezolizumab plus bevacizumab, resulting in a poor prognosis. Thus, the prediction and early detection of HCC is crucial. METHODS Patients with unresectable HCC treated with atezolizumab plus bevacizumab and had baseline preserved serum (n = 68) were screened and classified according to their PD, 6 weeks after treatment initiation (early PD; n = 13). Of these, 4 patients each with and without early PD were selected for cytokine array and genetic analyses. The identified factors were validated in the validated cohort (n = 60) and evaluated in patients treated with lenvatinib. RESULTS No significant differences were observed in the genetic alterations in circulating tumor DNA. Cytokine array data revealed that baseline MIG (CXCL9), ENA-78, and RANTES differed substantially between patients with and without early PD. Subsequent analysis in the validation cohort revealed that baseline CXCL9 was significantly lower in patients with early PD than that in patients without early PD, and the best cut-off value of serum CXCL9 to predict early PD was 333 pg/mL (sensitivity: 0.600, specificity: 0.923, AUC = 0.75). In patients with lower serum CXCL9 (<333 pg/mL), 35.3% (12/34) experienced early PD with atezolizumab plus bevacizumab, while progression-free survival (PFS) was significantly shorter relative to that in patients without (median PFS, 126 days vs. 227 days; HR: 2.41, 95% CI: 1.22-4.80, p = 0.0084). While patients with objective response to lenvatinib had significantly lower CXCL9 levels compared with those of patients without. CONCLUSION Baseline low serum CXCL9 (<333 pg/mL) levels may predict early PD in patients with unresectable HCC treated with atezolizumab plus bevacizumab.

Hepatitis C virus eradication by direct-acting antivirals causes a simultaneous increase in the prevalence of fatty liver and hyper-LDL cholesterolemia without an increase in body weight. Hepatol Res 2023. [PMID: 36945790 DOI: 10.1111/hepr.13899] [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: 12/15/2022] [Revised: 02/22/2023] [Accepted: 03/06/2023] [Indexed: 03/23/2023]
Abstract
AIM Hepatitis C virus (HCV) infection has been reported to cause liver steatosis. Thus, eradicating HCV with direct-acting antivirals (DAAs) is expected to reduce liver steatosis. We aimed to clarify long-term changes in the prevalence of fatty liver and hyper-LDL-cholesterolemia and their associations in patients who achieve successful HCV eradication using DAAs. METHODS This retrospective study included patients with HCV who achieved sustained virological response (SVR) after interferon-free DAA and analyzed the changes in the prevalence of fatty liver diagnosed with controlled attenuation parameter (CAP), hyper-LDL-cholesterolemia, and their relationships at baseline (n=100) and 24 weeks (SVR24, n=100), 96 weeks (SVR96, n=100), and 144 weeks (SVR144, n=90) after DAA. RESULTS In 100 participants, the prevalence of fatty liver (19% vs. 32%, p=0.0349) and hyper-LDL-cholesterolemia (6% vs. 15%, p=0.0379) significantly increased without changes in body weight at SVR96. Median total cholesterol, low-density lipoprotein cholesterol (LDL-C), and small-dense-LDL (sdLDL) levels and CAP values were significantly greater at SVR24, SVR96, and SVR144 than at baseline. Baseline CAP values and changes in CAP values were significantly negatively correlated at every observation point: r=-0.5305, p<0.0001 at SVR24; r=-0.3617, p=0.0005 at SVR96; and r=-0.4735, p<0.0001 at SVR144. A similar relationship was observed in cholesterol levels. Unlike at baseline, CAP values were significantly positively correlated with LDL-C and sdLDL-C levels at all observation points after DAAs. CONCLUSIONS DAAs may cause an increased prevalence of fatty liver accompanying hyper-LDL-cholesterolemia without increased body weight. Since post-SVR liver steatosis could cause HCC, careful follow-up may be required.

Prophylactic tenofovir alafenamide for hepatitis B virus reactivation and reactivation-related hepatitis. J Med Virol 2023; 95:e28452. [PMID: 36597900 DOI: 10.1002/jmv.28452] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2022] [Revised: 12/26/2022] [Accepted: 12/29/2022] [Indexed: 01/05/2023]
Abstract
No prospective study on the efficacy of tenofovir alafenamide (TAF), a novel tenofovir prodrug, in preventing hepatitis B virus (HBV) reactivation has yet been reported. This multicenter prospective study enrolled HBV-carriers who received TAF to prevent HBV reactivation before antitumor or immunosuppressive therapy, and patients with resolved HBV infection who experienced HBV-reactivation and received TAF to prevent HBV reactivation-related hepatitis. The efficacy of prophylactic TAF in preventing HBV reactivation and HBV reactivation-related hepatitis was evaluated at 6 and 12 months after initiating TAF. Overall, 110 patients were administered TAF to prevent HBV reactivation or HBV reactivation-related hepatitis. Three patients died owing to primary disease, whereas one patient was transferred to another hospital within 6 months after initiating TAF. Seven patients died due to primary disease, and five patients were transferred to another hospital within 12 months after initiating TAF. Therefore, 106 and 94 (77 patients with HBV infection, 17 with previous-HBV infection) patients were evaluated at 6 and 12 months after initiating TAF, respectively. No patient experienced HBV reactivation, HBV reactivation-related hepatitis, or treatment discontinuation due to HBV reactivation or adverse events of TAF after 6 and 12 months. TAF could effectively prevent HBV reactivation and HBV reactivation-related hepatitis.

Abstract
Glycosaminoglycans (GAGs), which are one of the major components of proteoglycans, play a pivotal role in physiological processes such as signal transduction, cell adhesion, growth, and differentiation. Characterization of GAGs is challenging due to the tremendous structural diversity of heteropolysaccharides with numerous sulfate or carboxyl groups. In this present study, we examined the analysis of 2-aminobenzamide (2-AB) labeled GAG disaccharides by high-performance liquid chromatography (HPLC) using a reverse-phase (RP)-column with adamantyl groups. Under the analytical conditions, 17 types of 2-AB labeled GAG disaccharides derived from heparan sulfate, chondroitin/dermatan sulfates, and hyaluronan were sequentially separated in a single analysis. The analysis time was fast with high retention time reproducibility. Moreover, the RP-HPLC column with adamantyl groups allowed the quantification of GAGs in various biological samples, such as serum, cultured cells, and culture medium.

Abstract
Progressive liver fibrosis after anti-HCV treatment is a risk factor for HCC. Angiopoietin-2 (Ang2) is associated with non-regression of liver fibrosis after direct-acting antiviral (DAA). This study evaluated the predictive value of serum Ang2 levels for HCC occurrence or recurrence after DAA administration. In this retrospective study, 310 HCV-infected patients treated with DAAs in 2014-2020 were screened and evaluated for HCC occurrence or recurrence every three-six months. Multivariate Cox regression analysis revealed that age ≥ 75 years (HR: 2.92, 95% CI: 1.34-6.33; p = 0.007) and baseline Ang2 level ≥ 464 pg/mL (HR: 2.75, 95% CI: 1.18-6.37; p = 0.019) were significantly associated with HCC occurrence after DAA therapy. A high or low risk of HCC after DAA therapy could be distinguished by the combination of age and baseline Ang2 level. The cumulative incidences of de-novo HCC at two and four years were 0.8% and 3.8% in the low-risk group and 22.6% and 27.1% in the high-risk group, respectively. Baseline Ang2 level ≥ 402 pg/mL was significantly associated with HCC recurrence in patients who achieved sustained virological response with DAAs (HR: 3.68). In conclusion, serum Ang2 levels can predict HCC occurrence and recurrence after successful HCV eradication by DAAs.

Abstract
Neuropathy with anti-myelin-associated glycoprotein (MAG) antibodies commonly demonstrates distal-dominant prolongation of nerve conduction. However, recent electrophysiological studies have shown that distal motor demyelination is not always a distinct feature. We aimed to elucidate whether the longitudinal progression of nerve impairment occurs in a distal-dominant manner. Seven patients with neuropathy with anti-MAG antibodies were enrolled. Sequential nerve conduction studies revealed nerve conduction reduction only at the wrist segment in the median nerve of the patients, but not in the ulnar nerve. Median nerve entrapment at the wrist may play a role in longitudinal disease progression in neuropathy with anti-MAG antibodies.

Abstract
De novo hepatitis B virus (HBV) reactivation occurs during direct-acting antiviral (DAA) treatment in hepatitis C virus (HCV)-infected patients with resolved HBV infection. We evaluated the predictive factors, mechanical insight, and differences of cytokine levels during anti-cancer/immunosuppressive and DAA. Eleven, 35, and 19 HCV-infected patients with previous HBV infection with HBV reactivation during DAA treatment, previous HBV infection without HBV reactivation during DAA treatment, and without HBV infection resolution receiving DAA treatment, respectively, were enrolled. Clinical data and baseline cytokine levels were analyzed. Low baseline serum interleukin (IL)-1β levels predicted de novo HBV reactivation during DAA treatment (odds ratio: 47.6, 95% confidence interval: 6.94-333.3). HCV-infected patients with the IL-1β gene single nucleotide polymorphism rs16944 AA allele had significantly higher IL-1β levels; no HCV-infected patient with the IL-1β AA allele experienced HBV reactivation during DAA treatment. Compared to HCV-infected patients with HBV infection resolution, non-HCV infected patients with or without HBV reactivation during anti-cancer/immunosuppressive therapy or bone marrow transplantation had remarkably lower baseline IL-1β levels. Low IL-1β levels were not associated with HBV reactivation. IL-1β levels before DAA for HCV-infected patients with resolved HBV infection could predict HBV reactivation during DAA treatment.

Abstract
BACKGROUND The Mac-2 binding protein glycosylation isomer (M2BPGi), a fibrosis marker in various liver diseases, is reportedly a prognostic marker in patients with hepatocellular carcinoma (HCC) who underwent hepatectomy.
AIM To evaluate whether the M2BPGi value, M2BP, and pre-sarcopenia before radiofrequency ablation (RFA) could be useful recurrence and prognostic markers in patients with early-stage HCC.
METHODS In total, 160 patients with early-stage primary HCC treated with RFA were separately analyzed as hepatitis C virus (HCV)-positive and HCV-negative. Factors contributing to recurrence and liver-related death, including M2BP, M2BPGi, and skeletal muscle mass index, were statistically analyzed. Eighty-three patients were HCV-positive and 77 were HCV-negative.
RESULTS In HCV-positive patients, only des-γ-carboxy-prothrombin ≥ 23 mAU/mL was a significant poor prognostic factor affecting survival after RFA. In HCV-negative patients, M2BPGi ≥ 1.86 cutoff index was significantly associated with tumor recurrence, while M2BP was not. M2BPGi ≥ 1.86 cutoff index (hazard ratio, 4.89; 95% confidence interval: 1.97-12.18; P < 0.001) and pre-sarcopenia (hazard ratio, 3.34, 95% confidence interval: 1.19-9.37; P = 0.022) were independent significant poor prognostic factors in HCV-negative patients.
CONCLUSION In HCV-negative patients with primary HCC treated with RFA, lower M2BPGi contributed to a lower tumor recurrence rate and longer survival period. Pre-sarcopenia contributed to the poor prognosis independently in HCV-negative patients. These factors might be useful recurrence and prognostic markers for early-stage primary HCC.

Abstract
BACKGROUND & AIMS Benefits of nucleos(t)ide analogs (NAs) on hepatitis B surface antigen (HBsAg) reduction and interferon-lambda3 (IFN-λ3) induction are still not known. This study aimed to investigate the effects of NAs on HBsAg reduction and association with serum IFN-λ3 levels in chronic hepatitis B (CHB) patients. METHODS A total of 91 patients [51 treated with nucleoside analog entecavir hydrate (ETV) and 40 treated with nucleotide analog adefovir dipivoxil (ADV) or tenofovir disoproxil fumarate (TDF)] with clinically evident CHB (chronic hepatitis, 57; liver cirrhosis, 34) were enrolled in this study. Serum IFN-λ3 levels among patients receiving ETV and ADV/TDF were measured before the initiation of therapy and 1, 3, and 5 years post-therapy. RESULTS The change (mean ± standard deviation) in serum HBsAg levels from baseline to year five was -0.38 ± 0.46 and -0.84 ± 0.64 log10 IU/ml in ETV and ADV/TDF groups, respectively (p = 0.0004). Higher serum IFN-λ3 levels were observed in ADV/TDF group compared with ETV group during treatment (p < 0.001). Serum IFN-λ3 levels showed negative correlation with HBsAg reduction in ADV/TDF group (r = -0.386, p = 0.038) at week 48. Nucleotide analogs (ADV/TDF) treatment has associated factors with -0.3 log HBsAg decline at 1 year, -0.5 log HBsAg decline at 3 years, and -0.8 log HBsAg decline at 5 years after NAs treatment on multivariate analysis. CONCLUSIONS Nucleotide analog (ADV/TDF) treatment reduced HBsAg levels greater compared with nucleoside analog (ETV) in parallel with IFN-λ3 induction.

Abstract
AIM A high prevalence of overestimated renal function in patients with liver cirrhosis (LC) has been reported; nonetheless, its impact on prognosis remains unclear. We aimed to evaluate the impact of overestimated renal function on prognosis in patients with LC. METHODS An overestimated renal function was defined as a >20% increase in the creatinine-based estimated glomerular filtration rate (eGFR), compared with cystatin C-based eGFR. LC patients with conserved serum, who were evaluated for muscle atrophy and had proper clinical information were included, and their prognostic factors were analyzed. RESULTS A total of 215 consecutive patients with LC were included. The prevalence of overestimated renal function was 29.8% (64/215). Kaplan-Meier survival analysis revealed that patients with overestimated renal function had a poorer prognosis than those without overestimated renal function (hazard ratio [HR]: 2.217 95% confidence interval [CI]: 1.290-3.810; p = 0.001). Subgroup analysis showed that overestimated renal function was a significant prognostic factor, irrespective of sex and the presence of hepatocellular carcinoma (HCC). Multivariate Cox regression analyses revealed that overestimated renal function was a significant and independent factor predictive of poor prognosis in the entire cohort (HR: 2.050; 95% CI: 1.041-4.037; p = 0.038) and in subgroups classified by Child-Pugh class A (HR: 2.131; 95% CI: 1.019-4.458; p = 0.044), Model for End-Stage Liver Disease score ≤9 (HR: 2.303; 95% CI: 1.038-5.109; p = 0.04), and presence of HCC (HR: 2.290; 95% CI: 1.128-4.651; p = 0.022). CONCLUSION Overestimated renal function is a significant and independent prognostic factor in patients with LC.

Abstract
Abstract
Study question
This study was to investigate effect of SERa on the fertilization rate, embryonic development after ICSI, and clinical and perinatal outcomes after single blastocyst transfer.
Summary answer
SERa (+) derived embryo can be selected as embryos for transfer when no available SERa (-) derived embryos.
What is known already
Based on findings that the risk of congenital abnormalities in the newborn is higher in ovum with SERa in the cytoplasm, the Istanbul consensus workshop at the 2011 meeting of the ESHRE recommended against fertilizing ovum with SERa due to these risks. However, there have been several reports of healthy infants born from embryos derived from SERa, suggesting that, while more long-term follow-up is necessary, healthy births are possible from such embryos. In 2017, the 2011 recommendations were reviewed in the Alpha/ESHRE consensus (Vienna), which said the approach should be determined on a case-by-case basis.
Study design, size, duration
We retrospectively investigated 23,007 oocytes which was retrieved between January 2016 and March 2020. Of these, 1,038 oocytes (4.5%) with visible SERa comprised SERa (+), while 21,969 oocytes (95.5%) without SERa comprised SERa (-).
Participants/materials, setting, methods
SERa were observed under the microscopy after denudation. The rate of fertilization, good-quality day-3 embryos, good-quality day-5 blastocysts, and day-5, 6 or 7 blastocysts were evaluated for both groups. We also compared the rate of clinical pregnancy, live birth, miscarriage, and birth defects in single blastocyst transfer between SERa (+) derived 114 blastocysts and SERa (-) derived 6,290 blastocysts from January 2016 and December 2018.
Main results and the role of chance
The results are shown. 2PN fertilization rate outcomes after ICSI (SERa(-) eggs vs. SERa(+)eggs),81.4%(17,873/21,969) vs.79.4% (823/1,038),and good-quality day3 rate was 61.1%(10,927/17,873)vs.60.9% (501/823) which was not significantly different. Good-quality day5 blastocyst rate was 46.5% (7,876/16,955) vs. 39.8%(304/763), and day 5 blastocyst success rate was 60.8% (10,317/16,955) vs.54.3% (414/763), which were both significantly lower with SERa(+). (P < 0.001) The day 6 blastocyst success rate was 69.9% (11,849/16,955) vs. 65.5% (500/763) (P = 0.01), and the day 7 blastocyst success rate was 70.9% (12,024/16,955) vs. 67.5% (515/763) (P = 0.04), which were all significantly lower with SERa(+).The clinical pregnancy rate was 39.4% (2,481/6,290) vs. 35.1% (40/114), the live birth rate was 27.7% (1,745/6,290) vs. 26.3% (30/114), and the miscarriage rate was 27.5% (683/2,481) vs. 20.0% (8/40) and the congenital abnormality rate was 1.6% (29/1,757) vs. 0% (0/30) for SERa(-) embryos and SERa(+) embryos, respectively, which were not significantly different. Blastocyst derived from oocytes with SERa has similar clinical and perinatal outcomes with those of oocytes without SERa. Significant differences were examined using the chi-squared test, with p < 0.05, indicating a significant difference.
Limitations, reasons for caution
Embryos derived SERa (+) were transferred when the patient did not want any more oocytes retrievals, no embryos derived SERa (-) were available, and only if the couple desired embryo transfer after the problems associated with SERa (+) embryos were fully explained.
Wider implications of the findings
To the best of our knowledge, this study is the largest number of live births investigating the outcome of SERa (+) derived embryos. SERa (+) derived embryo can be selected as embryos for transfer when no available SERa (-) derived embryos.

Abstract
Background Determining the number of chronic hepatitis B (HBV) and C virus (HCV) infections is essential to assess the progress towards the World Health Organization 2030 viral hepatitis elimination goals. Using data from the Japanese National Database (NDB), we calculated the number of chronic HBV and HCV infections in 2015 and predicted the trend until 2035. Methods NDB and first-time blood donors data were used to calculate the number of chronic HBV and HCV infections in 2015. A Markov simulation was applied to predict chronic infections until 2035 using transition probabilities calculated from NDB data. Findings The total number of chronic HBV and HCV infections in 2015 in Japan was 1,905,187–2,490,873 (HCV:877,841–1,302,179, HBV:1,027,346–1,188,694), of which 923,661–1,509,347 were undiagnosed or diagnosed but not linked to care (“not engaged in care”), and 981,526 were engaged in care. Chronic HBV and HCV infections are expected to be 923,313–1,304,598 in 2030, and 739,118–1,045,884 in 2035. Compared to 2015, by 2035, the number of persons with HCV not engaged in care will decline by 59·8 – 76·1% and 86·5% for patients in care. For HBV, a 47·3 – 49·3% decrease is expected for persons not engaged in care and a decline of 26·0% for patients engaged in care. Interpretation Although the burden of HBV and HCV is expected to decrease by 2035, challenges in controlling hepatitis remain. Improved and innovative screening strategies with linkage to care for HCV cases, and a functional cure for HBV are needed. Funding Japan Ministry of Health, Labour and Welfare.

Effect of switching from tenofovir disoproxil fumarate to tenofovir alafenamide on lipid profiles in patients with hepatitis B. PLoS One 2022; 17:e0261760. [PMID: 35051189 PMCID: PMC8775237 DOI: 10.1371/journal.pone.0261760] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2021] [Accepted: 12/09/2021] [Indexed: 12/22/2022] Open
Abstract
For long-term treatment of hepatitis B virus (HBV) infection, switching from tenofovir-disoproxil-fumarate (TDF) to tenofovir-alafenamide (TAF) may prevent renal dysfunction and bone loss. However, the precise effects of this switch on the blood lipid profile remain to be clarified. This is an important issue as TDF is known to have effects on both low- and high-density lipids. Therefore, our retrospective multi-center study aimed to evaluate the effects of switching from TDF to TAF on the lipid profile of patients with HBV infection. Samples were obtained prior to the switch from TDF to TAF and at 6-12 months after TAF initiation. In some cases, additional samples obtained pre- and post-TDF administration were available for analysis. Serum cholesterol levels, including oxidized-low-density lipoprotein (LDL) and non-high-density lipoprotein-cholesterol (HDL-c), and the rate of dyslipidemia, according to the NCEP-ATP III lipid risk classification, were analyzed. The data from 69 patients were analyzed, including 33 patients with pre- and post-TDF-initiation serum samples. Total cholesterol (T-chol), HDL-c, LDL-c, non-HDL-c, and oxidized LDL levels increased significantly after switching to TAF. With regard to sequential changes pre- to post-TAF, TDF was associated with significantly lower serum T-chol, HDL-c, and oxidized LDL-c levels, with T-chol, HDL-c, LDL-c, and oxidized LDL-c levels increasing significantly after the switch. The switch from TDF to TAF was also associated with an increase in the rate of dyslipidemia, from 33% to 39%, with an increase in the rate of severe dyslipidemia of 1.4% and 5.8%, based on T-chol and LDL-c levels. Of note, no cases of severe dyslipidemia were detected pre-TAF treatment. As oxidized LDL-c and non-HDL-c are strongly associated with atherosclerosis development, careful monitoring of lipid is needed after switching from TDF to TAF in this clinical population.

Abstract
Serum growth factor changes and their effect on prognosis during lenvatinib for unresectable hepatocellular carcinoma (HCC) remain underexplored. The sequential changes in serum growth factors during lenvatinib for unresectable HCC were evaluated in 58 patients using complete clinical data, and preserved serum was used to investigate changes in FGF-19, ANG-2, HGF, VEGF, and EGF. Patients with a complete response (CR), partial response (PR), and stable disease (SD) were evaluated for growth factor changes between the best response and progressive disease (PD) points, classified based on these changes, and evaluated by post progression survival (PPS). A total of 8, 24, 18, and 8 patients showed CR, PR, SD, and PD, respectively. Multivariate analysis revealed that age, relative dose intensity, and baseline ANG-2 were significantly associated with treatment response. Growth factor changes between the best response and PD points revealed that patients could be classified into four groups based on the EGF, ANG-2, and HGF changes. Although patient characteristics at baseline and PD, their response to lenvatinib, and PFS were similar among those groups, patients with an increase in all growth factors had significantly shorter PPS (median PPS was 553, 323, and 316 versus 173 days in groups 1-4 p = 0.032). We revealed that the evaluation of the changes in growth factors during lenvatinib could predict PPS.

Abstract
Chronic viral hepatitis is one of the most widespread infectious diseases in Japan. In the 2009 financial year, the Japanese government enacted the Basic Act on Hepatitis Measures, followed by the Basic Guidelines for Promotion of Control Measures for Hepatitis 2 years later. The guidelines emphasize the importance of provision and dissemination of accurate information on viral hepatitis and public awareness-raising. A subsidy program on hepatitis was therefore launched by the Ministry of Health, Labour and Welfare in 2011, called "Shitte kan-en" (in English, "Let's learn about hepatitis"), and involves popular Japanese actors and singers. The project started awareness-raising activities in the 2013 financial year, as the "National Campaign Project for Hepatitis Measures". It aims to communicate concise and accurate information about hepatitis and the necessity of testing for viral hepatitis. It also encourages citizens to take a positive approach to early detection and treatment. To date, the main initiatives of the project are as follows: i) celebrity visits to prefectural governors to draw attention to the condition, ii) educational events in cooperation with hepatologists in regional core hospitals, iii) support for partner companies' hepatitis awareness activities in workplaces, and iv) support for the activities of program promoters. Targeting approaches to particular groups is likely to be key to success for general awareness-raising. Evaluation of the effectiveness of this multifaceted approach is warranted to reduce the undiagnosed population and improve the link between testing and care for viral hepatitis in Japan.

Abstract
AIM A clinical trial (IMbrave150) indicated the efficacy and safety of atezolizumab plus bevacizumab for patients with unresectable hepatocellular carcinoma (HCC). In this study, we evaluated this therapeutic combination in a real-world setting, with a focus on patients who did not meet the IMbrave150 eligibility criteria. METHODS In this multicenter study, patients with unresectable HCC treated with atezolizumab plus bevacizumab between October 2020 and May 2021 were screened. In patients who did not meet IMbrave150 eligibility criteria, treatment responses and safety at 6 and 12 weeks were evaluated. RESULTS Atezolizumab plus bevacizumab was initiated in 64 patients, including 46 patients (71.9%) who did not meet IMbrave150 eligibility criteria. Most of these patients had a history of systemic therapy (44/46). The objective response rate and disease control rate observed using Response Evaluation Criteria in Solid Tumors 1.1 were 5.2% and 82.8% at 6 weeks and 10.0% and 84.0% at 12 weeks, respectively; these rates were similar between patients who met and did not meet the IMbrave150 criteria. Ten patients experienced progressive disease (PD) at 6 weeks. Portal vein tumor thrombosis was significantly associated with PD (p = 0.039); none of the 15 patients with hepatitis B virus-related HCC experienced PD (p = 0.050). The most common adverse events of grade 3 or higher were aspartate aminotransferase elevation (n = 8, 13.8%) and the safety profile was similar between patients who met and did not meet the IMbrave150 criteria. CONCLUSION Most patients treated with atezolizumab plus bevacizumab did not meet the IMbrave150 criteria; however, the combination therapy showed good safety and efficacy at the early treatment phase.

Lenvatinib suppresses cancer stem-like cells in HCC by inhibiting FGFR1-3 signaling, but not FGFR4 signaling. Carcinogenesis 2021; 42:58-69.

Abstract
In hepatocellular carcinoma (HCC), a subset of cells defined by high CD44 and CD133 expression has been reported to possess cancer stem-like cell (CSC) characteristics and to be associated with a poor prognosis. Since the approval of the multikinase inhibitor, lenvatinib, for patients with unresectable HCC, two such inhibitors (sorafenib and lenvatinib) have been employed as first-line systemic chemotherapeutics for these patients. Based on differences in the kinase-affinity profiles between these two drugs, evidence has suggested that both exert different effects on HCC, although these differences are not fully characterized. In this study, using in vitro and a preclinical in vivo xenograft mouse model, we showed that lenvatinib alone (not sorafenib or the cytotoxic agent, 5-fluorouracil) diminished CD44High/CD133High CSCs in HCC. Furthermore, western blotting and reverse transcriptase-polymerase chain reaction analysis revealed that the expression of fibroblast growth factor receptor (FGFR)-1-4 differed between CD44High/CD133High CSCs and control cells. Analysis of the effects of selective FGFR inhibitors and FGFR small interfering RNAs on CSCs in HCC revealed that lenvatinib diminished CSCs in HCC by inhibiting FGFR1-3 signaling, however, FGFR4 signaling was not impacted. Finally, we showed that FGF2 and FGF19 were involved in maintaining CD44High/CD133High CSCs in HCC, potentially, via FGFR1-3. The findings provide novel mechanistic insights into the effects of lenvatinib on CSCs in HCC and provide clues for developing effective targeted therapies against CSCs in HCC.

Changes in the estimated renal function after hepatitis C virus eradication with direct-acting antiviral agents: Impact of changes in skeletal muscle mass. J Viral Hepat 2021; 28:755-763.

Abstract
Hepatitis C virus (HCV) infection can cause renal dysfunction, expected to improve upon HCV eradication. However, adverse effects of HCV eradication using direct-acting antiviral agents (DAAs) on renal function have been recently reported. This retrospective study aimed to evaluate renal function with glomerular filtration rate (eGFR) estimated using creatinine (eGFRcre) and cystatin C (eGFRcys). Complete clinical information and preserved serum samples were collected from 207 patients with HCV infection treated with interferon-free DAA at baseline and SVR48 (SVR48). Patients who underwent paired computed tomography (CT) at baseline and ≥12 months after DAA were evaluated for changes in skeletal muscle mass using the psoas muscle mass index (PMI). eGFRcre significantly worsened at SVR48, while eGFRcys was similar at baseline and SVR48. At baseline, eGFRcre was significantly higher than eGFRcys; eGFRcre and eGFRcys were similar at SVR48. Multivariate analysis revealed that the presence of liver cirrhosis and low-albumin level, as well as cirrhosis and age, was significantly associated with the overestimation of renal function by eGFRcre at baseline and SVR48, respectively. In the 57 patients who underwent paired CT at baseline and ≥12 months after DAA, relative values of PMI significantly increased after DAA. After DAA, in patients with increased PMI (65% 37/57), eGFRcre significantly worsened but did not change in patients without increased PMI. eGFRcre significantly worsened after DAAs; however, this might not reflect accurate changes in renal function, partially because of changes in skeletal muscle mass. eGFRcys did not change after DAAs, and it is a potential alternative to eGFRcre.

Abstract
A deteriorated liver functional reserve during systemic therapy for unresectable hepatocellular carcinoma (HCC) causes poor patient outcomes. We aimed to identify predictive factors associated with the deterioration of Child-Pugh score at 8 weeks after lenvatinib initiation. Patients with adequate clinical data and baseline preserved serum samples available were included. Baseline fibroblast growth factor (FGF)19 and 21, angiopoietin (ANG)2, and vascular endothelial growth factor (VEGF) levels were evaluated. Thirty-seven patients were included, and 6, 15, 14, and 2 experienced complete response, partial response, stable disease, and progressive disease, respectively. Twenty-four (65%) and 13 (35%) patients showed a maintained/improved and deteriorated Child-Pugh-score, respectively. While baseline clinical data, treatment response, and laboratory data were similar between these two patient groups, baseline ANG2 and VEGF levels were significantly higher (P = 0.0017) and lower (P = 0.0231), respectively, in patients with deteriorated Child-Pugh score than in those without. Based on receiver operating characteristic curve analysis, cut-off values for ANG2 and VEGF were found to be 3,108 pg/mL and 514.9 pg/mL, respectively. Among patients with low VEGF and high ANG2, 89% (8/9) exhibited a deteriorated Child-Pugh score, whereas none of the patients (0/9) with high VEGF and low ANG2 did. The deterioration of the Child-Pugh score in patients with unresectable HCC who are treated with lenvatinib may be predictable based on combined baseline serum ANG2 and VEGF levels.

Tenofovir-disoproxil-fumarate modulates lipid metabolism via hepatic CD36/PPAR-alpha activation in hepatitis B virus infection. J Gastroenterol 2021; 56:168-180.

Abstract
BACKGROUND Entecavir and tenofovir-disoproxil-fumarate are first-line nucleos(t)ide analogs (NA) for treatment of hepatitis B virus (HBV) infections; however, their long-term administration can impact extrahepatic organs. Herein, we sought to examine the effect of NA on lipid metabolism while also characterizing the associated mechanism. METHODS A retrospective study was performed on HBV patients administered entecavir or tenofovir-disoproxil-fumarate. Patient clinical information, as well as their preserved serum samples obtained at baseline and 6-12 months after treatment initiation, were analyzed. A 1:1 propensity score matching was applied to the assignment of tenofovir-disoproxil-fumarate or entecavir treatment. Changes in serum cholesterol, including oxidized-LDL, were analyzed. Subsequently, in vitro analysis elucidated the mechanism associated with the effect of NAs on lipid metabolism. RESULTS Administration of tenofovir-disoproxil-fumarate, not entecavir, to chronic HBV patients, decreased serum cholesterol levels, including non-HDL and oxidized-LDL, which are strongly associated with arteriosclerosis. In vitro analysis revealed that tenofovir-disoproxil-fumarate reduced supernatant cholesterol, and upregulated the scavenger receptor, CD36, in hepatocytes. Meanwhile, silencing of hepatic CD36 increased supernatant cholesterol and negated the cholesterol-reducing effect of tenofovir-disoproxil-fumarate in HepG2-cells. Reporter, microarray, and RT-PCR analyses further revealed that tenofovir-disoproxil-fumarate treatment activates PPAR-α-mediated signaling, and upregulates PPAR-α target genes, including CPT1 and CD36. Alternatively, silencing of PPAR-α reversed the effects of tenofovir-disoproxil-fumarate on CD36. CONCLUSIONS Tenofovir-disoproxil-fumarate modulates lipid metabolism by upregulating hepatic CD36 via PPAR-α activation. Since dyslipidemia could be associated with arteriosclerosis and hepatocarcinogenesis, these discoveries provide novel insights into anti-HBV therapies, as well as the associated extrahepatic effects of NA.

Time-dependent changes in the seroprevalence of COVID-19 in asymptomatic liver disease outpatients in an area in Japan undergoing a second wave of COVID-19. Hepatol Res 2020; 50:1196-1200.

Abstract
AIM Coronavirus disease 2019 (COVID-19) is a serious public health concern, with unclarified prevalence in Japan. Concomitant liver disease could increase the severity of COVID-19 disease, and chronic liver disease patients sometimes require frequent admission and gastrointestinal endoscopy. Thus, clarifying the prevalence of asymptomatic COVID-19 in outpatients with liver disease is essential for preventing nosocomial infections. We aimed to clarify the time-dependent changes in COVID-19 seroprevalence in liver disease outpatients, who were asymptomatic for COVID-19, in an area of Japan experiencing a second wave of COVID-19. METHODS We included the preserved sera of 100, 300, and 300 consecutive liver disease outpatients, who were asymptomatic for COVID-19, from May 2019, March 2020, and May 2020, respectively. The sera were analyzed immunochromatographically to detect immunoglobulin G against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (KURABO) and by Elecsys Anti-SARS-CoV-2-assay (Roche Diagnostics). RESULTS Analysis of 100 cases from May 2019, before COVID-19 became pandemic, revealed that the specificity of immunochromatographic tests and Elecsys were 98% (95% confidence interval [CI], 93-99.8%) and 100% (95% CI, 97-100%), respectively. Analysis of 300 cases from March 2020 revealed a seroprevalence of 0.3% (1/300; 95% CI, 0-1.8%) for COVID-19 by Elecsys Anti-SARS-CoV-2 assay. Analysis of 300 cases from May 2020 revealed a seroprevalence of 0% (0/300; 95% CI, 0-1.0%). CONCLUSIONS The Elecsys Anti-SARS-CoV-2 assay has high specificity. The cumulative seroprevalence of COVID-19 by the Elecsys Anti-SARS-CoV-2 assay in outpatients with liver disease in Sapporo, who were asymptomatic for COVID-19, was 0.17% (1/600; 95% CI, 0.0-0.9%) until May 2020.

Prevalence, clinical course, and predictive factors of immune checkpoint inhibitor monotherapy-associated hepatitis in Japan. J Gastroenterol Hepatol 2020; 35:1782-1788. [PMID: 32187734 DOI: 10.1111/jgh.15041] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2020] [Revised: 03/03/2020] [Accepted: 03/09/2020] [Indexed: 12/11/2022]
Abstract
BACKGROUND AND AIM Immune checkpoint inhibitors (ICI) have revolutionized anti-malignancy therapy and thus have been increasingly used. Although ICI may cause immune-related adverse events (irAE) in various organs, including the liver, the prevalence and predictive factors of irAE have not been clarified. METHODS In this retrospective study, consecutive patients who had malignancies and were treated with ICI without other chemotherapeutic agents at Hokkaido University Hospital between 2014 and 2019 were screened. Patients were excluded if they were < 20 years old and had insufficient clinical data. RESULTS Of the 233 patients screened, 202 patients met the inclusion criteria and were included in the analysis. The patients were aged 25-92 years, and 60.9% were male. The patients received nivolumab (n = 137), pembrolizumab (n = 45), ipilimumab (n = 17), atezolizumab (n = 2), and avelumab (n = 1). The prevalence of any grade and grade ≥ 3 irAE hepatitis was 8.4% (17/202) and 4.0% (8/202), respectively. irAE hepatitis occurred at a median duration of 42 days in any grade and 36 days in grade ≥ 3 after ICI initiation. The clinical course of grade ≥ 3 irAE hepatitis was generally favorable; however, 50% required corticosteroid treatment and two patients required additional mycophenolate mofetil. Female sex and history of ICI treatment were significantly associated with the incidence of grade ≥ 3 irAE hepatitis. CONCLUSIONS Grade ≥ 3 irAE hepatitis was observed in 4.0% of the patients who were treated with ICI. Female sex and history of ICI treatment were significantly associated with the incidence of grade ≥ 3 irAE hepatitis.

Oleoylethanolamide Ameliorates Dextran Sulfate Sodium-Induced Colitis in Rats. Front Pharmacol 2020; 11:1277.

Abstract
Oleoylethanolamide (OEA) is an endogenous fatty acid ethanolamide known for its anti-inflammatory effects and its influence on gut microbiota composition; however, the effects of OEA in inflammatory bowel disease (IBD) remain unknown. During in vitro experiments, OEA downregulated the expression of tumor necrosis factor (TNF)-α and reduced phosphorylation of inhibitor of kappa (Iκ) Bα induced by lipopolysaccharide in human embryonic kidney cells. Moreover, OEA downregulated the expression of interleukin (IL)-8 and IL-1β and inhibited the phosphorylation of IκBα and p65 induced by TNF-α in human enterocytes (Caco-2). The effect of OEA in reducing the expression of IL-8 was blocked by the peroxisome proliferator-activated receptor (PPAR)-α antagonist. During in vivo experiments on rats, colitis was induced by the oral administration of 8% dextran sulfate sodium from day 0 through day 5, and OEA (20 mg/kg) was intraperitoneally injected once a day from day 0 for 6 days. OEA administration significantly ameliorated the reduction in body weight, the increase in disease activity index score, and the shortening of colon length. In rectums, OEA administration reduced the infiltration of macrophages and neutrophils and tended to reduce the histological score and the expression of inflammatory cytokines. Administration of OEA produced significant improvement in a colitis model, possibly by inhibiting the nuclear factor kappa B signaling pathway through PPAR-α receptors. OEA could be a potential new treatment for IBD.

Abstract
AIM This study aimed to determine the efficacy and safety of lenvatinib for patients with unresectable hepatocellular carcinoma (HCC) who did not meet REFLECT eligibility criteria (phase 3 clinical trial). METHODS In this multicenter retrospective study, patients with unresectable HCC treated with lenvatinib between 2018 and 2019 and had adequate clinical data were included. Objective response rate, progression-free-survival (PFS) and safety were evaluated according to meeting or not meeting the REFLECT eligibility criteria and according to the criteria of the REFLECT trial. RESULTS Of the 105 patients included, 61% (64 of 105) did not meet the REFLECT eligibility criteria. Safety and median PFS of lenvatinib were similar between the patients who did and those who did not meet the criteria. Among the patients who did not meet the criteria, 28, 27, 14, six, seven and five had a history of tyrosine kinase inhibitor (TKI) treatment, Child-Pugh score B, HCC in ≥50% of the liver, reduced platelet count, bile duct invasion and main portal vein invasion, respectively. The efficacy and safety of lenvatinib for patients with or without Child-Pugh-score B or HCC in ≥50% of the liver were similar. Although treatment outcome was not significantly different, patients with TKI treatment history tended to have longer median PFS, whereas those with main portal vein invasion tended to have shorter median PFS. CONCLUSION Lenvatinib was effective for patients who did not meet the REFLECT inclusion criteria. However, the treatment outcome may vary according to several factors, such as a history of TKI treatment and tumor invasion.

Abstract
Background:The treatment of rheumatoid hand, which is characterized by thumb deformity, finger deformities, and ulnar drift (UD), is challenging. Its pathophysiology is complex, and a comprehensive understanding of the optimal intervention for this condition requires high technical skill and extensive clinical experience. Moreover, the natural course of rheumatoid hand itself remains unclear.Objectives:This study was performed to comprehensively evaluate rheumatoid hand through the specific parameters of each deformity.Methods:A rheumatoid hand cohort was established in 2004. In total, 134 hands of 67 patients were registered and underwent clinical evaluations. All hands surgically treated during follow-up were excluded from the study, but the contralateral hands were assessed. Evaluations were repeated in 2009 (100 hands of 52 patients) and in 2015 (63 hands of 37 patients) among all available patients. Therefore, among the data obtained from the 3 study endpoints, 297 hands were available for the cross-sectional analysis and 43 hands were available for the longitudinal analysis.Thumb deformities and finger deformities (swan-neck and boutonnière) were semi-quantitated by the Nalebuff classification score, and UD was quantified using a metacarpophalangeal joint condition scoring method1). A two-step cluster analysis was performed with entered parameters, and the distribution of each parameter was considered to clarify the characteristics of each cluster. The hands with different clusters at each endpoint were recruited for the following longitudinal analysis. The natural course of rheumatoid hand was considered based on the cluster change.Results:Seven clusters were used in this study to emphasize the impact of thumb deformity on function. The characteristics of each cluster were as follows. Cluster 1: mild finger deformities and various severities of UD; Cluster 2: type 1 thumb deformity and various severities of UD; Cluster 3: type 2 thumb deformity and severe UD; Cluster 4: type 3 or 4 thumb deformity, low or moderate level of swan-neck deformity, and various severities of UD; Cluster 5: various types of thumb deformity, severe boutonnière deformity, and various severities of UD; Cluster 6: type 1 thumb deformity, severe swan-neck deformity, and various severities of UD; and Cluster 7: type 6 thumb deformity.The longitudinal analysis showed that Cluster 1 mainly changed to Cluster 2 or 4, indicating progression of thumb deformity. Cluster 2 changed to Cluster 3, indicating that thumb type 1 progressed to type 2 (Figure 1). When the affected period was shorter than 10 years, the incidence of severe hand deformity (including two or more affected joint areas and low hand function) was <10%. In contrast, when the affected period was longer than 10 years, the incidence of severe hand deformity was >30% (Figure 2).Figure 1.Figure 2.Conclusion:This study suggests the presence of seven patterns of deformity enabling a comprehensive understanding of rheumatoid hand. Furthermore, the results of the longitudinal analysis suggest a natural course of rheumatoid hand progression. Therefore, from the distribution of parameters of each deformity and its severity, rheumatologists can easily classify rheumatoid hand and determine its pathophysiology to choose the most effective intervention.References:[1]Toyama S, Oda R, Tokunaga D et al.

Abstract
UNLABELLED This study aimed to determine the optimal psoas muscle mass index (PMI) cut-off values for diagnosis of skeletal muscle mass loss. METHODS We evaluated PMI in two groups of normal controls: a medical check-up group and a liver donation candidate group. We analyzed two novel PMI cut-off values, one based on the mean - two standard deviations (2SD) and one based on the lower 5%. Skeletal muscle mass index (SMI) evaluations using computed tomography (sliceOmatic; TomoVision) and bioelectrical impedance analysis and PMI evaluation were undertaken simultaneously. We analyzed the correlation between our PMI cut-off values and the Japan Society of Hepatology-defined SMI cut-off values. The prevalence of skeletal muscle mass loss in patients with liver disease was assessed using the novel PMI cut-off values. RESULTS In 504 normal controls aged ≤50 years, the PMI cut-off values based on mean -2SD and the lower 5% were set at 3.30 cm2 /m2 for men and 1.69 cm2 /m2 for women and 3.74 cm2 /m2 for men and 2.29 cm2 /m2 for women, respectively. The PMI cut-off values based on the lower 5% alone showed that skeletal muscle mass loss increased with age. Furthermore, they correlated well with Japan Society of Hepatology-defined SMI (sliceOmatic) cut-off values and showed a significantly higher prevalence of skeletal muscle mass loss in patients with liver cirrhosis than those without liver cirrhosis. CONCLUSIONS We propose the following PMI cut-off values: 3.74 cm2 /m2 for male individuals and 2.29 cm2 /m2 for female individuals. These cut-off values can facilitate accurate diagnosis and management of sarcopenia in patients with chronic liver disease.

High serum angiopoietin-2 level predicts non-regression of liver stiffness measurement-based liver fibrosis stage after direct-acting antiviral therapy for hepatitis C. Hepatol Res 2020; 50:671-681.

Abstract
AIM Factors associated with improvement of liver fibrosis after successful hepatitis C virus (HCV) eradication by interferon (IFN)-free direct-acting antiviral agents (DAAs) have been not clarified well. Angiopoietin-2 (Ang2) is reported to be associated with vascular leak and inflammation observed in patients with advanced liver fibrosis. METHODS In this retrospective study, patients treated with IFN-free DAAs who underwent transient elastography before and at 24-weeks post-treatment and achieved sustained viral response were enrolled. Baseline serum Ang2 was measured, and its relationship with other clinical factors was analyzed. Liver fibrosis stage was defined based on liver stiffness according to a previous report. Predictive factors for regression of liver fibrosis stage after DAA therapy were evaluated. RESULTS Overall, 116 patients were analyzed. Baseline serum Ang2 levels were significantly associated with liver stiffness, spleen index, and liver stiffness-based liver fibrosis stage. Moreover, 75% of patients experienced regression of liver fibrosis stage after DAA therapy. Multivariate analysis revealed that advanced liver fibrosis stage and Ang2 levels were significantly associated with regression of liver fibrosis stage after DAA therapy. In patients with advanced liver fibrosis (F3/4), baseline Ang2 level alone could predict regression of liver fibrosis stage. A baseline Ang2 cut-off value (354 pg/ML) could predict regression of liver fibrosis stage after DAA therapy with high accuracy (sensitivity 0.882, specificity 0.733). CONCLUSIONS Evaluation of serum Ang2 levels before DAA therapy is important. Our results provide a novel mechanistic insight into non-regression of liver stiffness after DAA therapy. Long-term and larger studies are required.

Abstract
Background Sorafenib and lenvatinib are first‐line systemic therapies for unresectable hepatocellular carcinoma (HCC). However, the criteria for their selection remain unclear. Methods We identified patients with unresectable HCC who were treated with sorafenib or lenvatinib between August 2009 and January 2019 at the Hokkaido University Hospital. Patients who continued treatment for >2 months, underwent evaluation by computed tomography every 2–3 months, and had complete clinical data were included. Responders were patients with objective response (OR) for lenvatinib and patients with stable disease (SD) exceeding 6 months (long‐SD) or OR for sorafenib. The predictive factors for treatment response, including fibroblast growth factor (FGF)19 and 21, angiopoietin 2 (ANG2), hepatocyte growth factor, and vascular endothelial growth factor, were evaluated. Results Overall, 27 and 29 patients treated with lenvatinib and sorafenib, respectively, were included. The responders for lenvatinib and sorafenib were 63% (17/27) and 38% (11/29), respectively. No significant predictive factors for treatment response were identified in patients treated with sorafenib. However, baseline serum FGF19 and ANG2 levels were significantly associated with treatment response to lenvatinib. All (9/9) patients with low baseline ANG2 and FGF19 levels who received lenvatinib achieved OR. Conversely, the OR was low (13%; 1/9) in patients with high baseline ANG2 and FGF19 levels. Responder rate was 40% (2/5) in patients with high baseline ANG2 and FGF19 levels who received sorafenib. Conclusion This study is, to our knowledge, the first to demonstrate that baseline ANG2 and FGF19 levels may aid in selecting optimal systemic therapy for patients with unresectable HCC.

Abstract
AIMS Development of direct-acting antivirals (DAAs) has made antihepatitis C virus (HCV) treatment highly safe and effective. However, the emergence of resistant-associated variants (RAVs) after failure of DAA therapy affects retreatment outcomes. In particular, genotype 1 HCV with P32 deletion has been reported to be highly resistant to all approved non-structural protein (NS)5A inhibitors. However, analysis of RAVs in genotype 2 HCV has been limited. Accordingly, in this study, we evaluated the roles of genotype 2 HCV variants in antiviral drug efficacy. METHODS We utilized HCV-2b/2a (JFH-1) chimeric virus (genotype 2a), which replicates more robustly than JFH-1. We constructed various genotype 2a JFH-1-based HCV cell culture systems with NS3 (D168E), NS5A (F28S, F28S/M31I, P32 deletion, and Y93H), and NS5B (S282 T) RAVs and analyzed the replication ability and sensitivity to various anti-HCV reagents. RESULTS Genotype 2a-based HCV with NS5A-P32 deletion could not replicate even in long-term cultures. Genotype 2a-based HCV with NS5A-F28S/M31I showed significantly higher replication ability than the wild-type strain, and replication could not be suppressed, even with high concentrations of NS5A inhibitors, including pibrentasvir and velpatasvir (<1000-10 000 fold-resistance compared with the wild-type strain). However, genotype 2a-based HCV with NA5A-F28S/M31I was sensitive to HCV protease inhibitor, NS5B inhibitor, interferon-α, and ribavirin. Genotype 2a-based HCV with NS5B-S282 T was resistant to sofosbuvir, but was highly sensitive to ribavirin compared with the control. CONCLUSIONS When undertaking retreatment for genotype 2a HCV-infected patients who fail to respond to DAAs, the optimized retreatment should be chosen according to the sensitivity of the emerging RAVs to anti-HCV drugs.

Abstract
AIM Entecavir (ETV), tenofovir disoproxil fumarate (TDF), and tenofovir alafenamide (TAF) are first-line nucleos(t)ide analogues for hepatitis B virus (HBV)-infected patients. However, consecutive TDF treatment causes renal dysfunction, and the safety and efficacy of TAF have not been established in severe renal dysfunction patients, including hemodialysis patients. The efficacy and safety of ETV in these populations has not been clarified. The study aimed to clarify this. METHODS In this retrospective multicenter study, between 2006 and 2018, a total of 567 HBV-infected patients treated with ETV monotherapy were screened. Patients were included if >20 years old, treated with ETV monotherapy for >1 year, and had proper clinical information. The efficacy of ETV and changes in renal function were evaluated according to renal function. RESULTS A total of 273 patients were included: 9.2% (25/273), 1.8% (5/273), and 3.7% (10/273) had chronic kidney disease (CKD) stage G3, CKD stage G4/5, and were on hemodialysis, respectively. Overall, 84.2%, 94.0%, and 96.2% of patients experienced serum HBV-DNA disappearance at 1, 2, and 3 years, respectively, after treatment initiation. In patients with CKD stage G3-5, estimated glomerular filtration rate tended to restore with time, which was in contrast to patients without renal dysfunction. The rate of disappearance in serum HBV-DNA, alanine transaminase normalization, and virological breakthrough was similar between patients with or without renal dysfunction. ETV showed high efficacy for all 10 hemodialysis patients without virological breakthrough. CONCLUSIONS Entecavir for HBV-infected patients with severe renal dysfunction, including hemodialysis patients, is highly effective and does not affect renal function.

Abstract
AIM Ultrasound technology can now be used for liver stiffness measurement (LSM) and for evaluating the amount of hepatic fat quantitatively known as the controlled attenuation parameter (CAP). This study aimed to determine the applicable cut-off values of LSM and the CAP for primary hepatocellular carcinoma (HCC), and to investigate their clinical usefulness for assessing HCC risk in patients with chronic liver disease. METHODS A total of 1054 patients (88 with primary HCC and 966 without HCC) whose LSM and the CAP were measured by transient elastography with clinically evident hepatitis C virus (419 patients), hepatitis B virus (377 patients), and non-alcoholic fatty liver disease (258 patients) were enrolled in this study. Subsequently, a total of 966 patients who did not have HCC initially were followed, and the usefulness of the cut-off values of LSM and CAP for HCC development were evaluated. RESULTS In hepatitis C virus patients, the incidence of HCC development was significantly higher among those with a combination of LSM ≥8.0 kPa and CAP ≤221 dB/m than among those with other values (log-rank test 0.0239, hazard ratio 2.66, 95%CI 1.07-6.47, P = 0.0362). In non-alcoholic fatty liver disease patients, the incidence of HCC development was significantly higher among those with a combination of LSM ≥5.4 kPa and CAP ≤265 dB/m than among others (log-rank test 0.0040, hazard ratio 8.91, 95% CI 1.47-67.97, P = 0.0192). CONCLUSION In the hepatitis C virus and non-alcoholic fatty liver disease groups, a combination of LSM and the CAP cut-off values would be useful for screening to identify the high-risk group for primary HCC development.

Abstract
Background and Aim Lenvatinib has been recently approved as a first‐line systematic therapy for patients with advanced hepatocellular carcinoma (HCC) based on the results of the phase 3 clinical trial REFLECT. This trial excluded patients with a history of systemic chemotherapy, bile duct invasion, and Child‐Pugh grade B. We aimed to investigate the efficacy and safety of lenvatinib for these patients and in the real‐world setting. Methods Among patients who were administered lenvatinib for advanced HCC between April and October 2018 in Hokkaido University Hospital and related hospitals, we evaluated those who were followed for more than 2 months and whose treatment response was evaluated via dynamic computed tomography at baseline and 2 months after treatment initiation. Meanwhile, patients were excluded if they had decompensated liver cirrhosis, were followed up less than 2 months, or were not evaluated at 2 months. Patients were also stratified according to compliance with the REFLECT inclusion criteria for further analysis. Results A total of 41 patients were included; more than 50% did not meet the REFLECT inclusion criteria. In total, 5 (12.2%), 20 (48.8%), 12 (29.3%), and 4 (9.3%) showed complete response, partial response, stable disease, and progressive disease, respectively. The objective response rate was 61.2%. The objective response rate and disease control rate were similar between patients who did and did not meet the REFLECT inclusion criteria. Moreover, the safety profile was also similar between the two patient groups. Conclusion Lenvatinib showed high early response rate and tolerability in patients with advanced HCC. Favorable outcomes were similarly observed in patients who did not meet the REFLECT inclusion criteria.

Abstract
Clinical trials and real-world data have proven that hepatitis C virus (HCV) in most infected patients can be eradicated by direct-acting antivirals (DAAs). However, the proper retreatment regimen for hemodialysis patients with HCV infection who have previously failed to respond to DAAs has not been clarified. We herein report, for the first time, the successful retreatment with glecaprevir and pibrentasvir, of three hemodialysis patients with genotype 1 or 2 HCV infection, who had previously failed to respond to combination therapy with an HCV-NA5A inhibitor (daclatasvir) and an HCV protease inhibitor (asunaprevir).

Abstract
The efficacy and safety of glecaprevir and pibrentasvir in Japanese patients with human immunodeficiency virus (HIV) and/or genotype 3 hepatitis C virus (HCV) infection is yet to be clarified. This is because no or only a few patients have been included in Japanese phase 3 trials. We herein report for the first time the successful treatment of glecaprevir and pibrentasvir in three Japanese patients with HIV and genotype 3 HCV coinfection as well as hemophilia. Glecaprevir and pibrentasvir treatment is safe and effective for Japanese patients with genotype 3 HCV and HIV coinfection.

Impaired residual renal function predicts denosumab-induced serum calcium decrement as well as increment of bone mineral density in non-severe renal insufficiency. Osteoporos Int 2019; 30:241-249. [PMID: 30187112 DOI: 10.1007/s00198-018-4688-1] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2018] [Accepted: 08/26/2018] [Indexed: 12/27/2022]
Abstract
UNLABELLED Denosumab treatment of osteoporotic patients, except those with severe renal insufficiency, reduced cCa levels. Low baseline cCa, low estimated glomerular filtration rate, and high bone turnover increased the risk of lower cCa, while increasing bone mineral density. Pretreatment with antiresorptive agents was beneficial in reducing the risk of hypocalcemia. INTRODUCTION Although denosumab-induced hypocalcemia has been frequently observed in patients with chronic kidney disease (CKD) stages 4-5D being treated with denosumab for osteoporosis, few studies have assessed the risk factors for serum-corrected calcium (cCa) reductions in patients with non-severe renal insufficiency. This study assessed the risk factors for reduced cCa concentration following denosumab administration and analyzed factors predictive of changes in bone mineral density (BMD). METHODS Seventy-seven osteoporotic patients, not including those with CKD stages 4-5D, were treated with 60 mg denosumab once every 6 months. Biochemical parameters and BMD were analyzed from prior to the initial dose until 1 month after the second dose. RESULTS Following the first administration of denosumab, cCa levels decreased, reaching a minimum on day 7. Multiple linear regression analyses showed that baseline cCa, estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m2, tartrate-resistant acid phosphatase-5b (TRACP-5b), and bone alkaline phosphatase (BAP) or pretreatment with antiresorptive agents were significant factors independently associated with the absolute reduction in cCa from baseline to day 7 (ΔcCa0-7 days). ΔcCa0-7 days after the second dose of denosumab was significantly lower than that after the first dose. After 6 months of denosumab treatment, both LS-BMD and FN-BMD significantly increased from baseline. LS-BMD and FN-BMD correlated significantly with baseline TRACP-5b or BAP and eGFR, respectively. CONCLUSIONS Both low eGFR and high bone turnover were independent risk factors for denosumab-induced cCa decrement, and for increases in BMD. Pretreatment with antiresorptive agents may reduce the risk of hypocalcemia.

Safety and efficacy of elbasvir and grazoprevir in Japanese hemodialysis patients with genotype 1b hepatitis C virus infection. J Gastroenterol 2019; 54:78-86. [PMID: 30019127 DOI: 10.1007/s00535-018-1495-6] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/17/2018] [Accepted: 07/06/2018] [Indexed: 02/04/2023]
Abstract
BACKGROUND The prevalence of hepatitis C virus (HCV) infection in hemodialysis patients is high and results in a poor prognosis. Thus, safer and more effective treatment regimens are required. In this prospective multicenter study, we investigated the efficacy and safety of the novel HCV-NS5A-inhibitor, elbasvir, and protease inhibitor, grazoprevir in Japanese hemodialysis patients with genotype 1b HCV infection. METHODS This study is registered at the UMIN Clinical Trials Registry as UMIN00002578. A total of 23 Japanese dialysis patients with genotype 1b HCV infection who were treated with elbasvir and grazoprevir between January 2017 and March 2018 and followed for more than 12 weeks after treatment completion were included. We evaluated the sustained virologic response at 12 weeks after treatment completion (SVR12) and safety during treatment. RESULTS Of the 23 patients, 7 had advanced liver fibrosis and 2 had a signature resistance-associated variant of NS5A (NS5A RAVs)-L31M/V or Y93H at baseline. All patients completed therapy, and 96.7% (22/23) of the patients achieved SVR12. All patients with advanced liver fibrosis and signature NS5A RAVs at baseline achieved SVR12 with a high safety profile. No patient experienced lethal or severe adverse events during therapy, and the most common adverse event was anemia. One patient, who was a non-responder to this therapy, had a history of failure with daclatasvir and asunaprevir therapies and had NS5A RAVs of A92K at baseline, but not signature NS5A RAVs. CONCLUSIONS Grazoprevir and elbasvir combination is highly effective and safe for hemodialysis patients with genotype 1b HCV infection.

Liver steatosis and dyslipidemia after HCV eradication by direct acting antiviral agents are synergistic risks of atherosclerosis. PLoS One 2018; 13:e0209615. [PMID: 30576386 PMCID: PMC6303061 DOI: 10.1371/journal.pone.0209615] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2018] [Accepted: 11/28/2018] [Indexed: 12/11/2022] Open
Abstract
Aim We comprehensively analyzed how hepatitis C virus (HCV) eradication by interferon (IFN)-free direct-acting-antiviral-agents (DAAs) affects liver steatosis and atherogenic risk. Methods Patients treated with IFN-free-DAAs who underwent transient elastography before and at 24-weeks post-treatment, including controlled attenuation parameter (CAP), and achieved sustained viral response (SVR) were enrolled. The association between changes in liver steatosis, lipid-metabolism, and genetic and clinical factors was analyzed. Results A total of 117 patients were included. The mean CAP and low-density lipoprotein cholesterol (LDL-C) levels were significantly elevated at SVR24. However, baseline LDL-C and CAP values were significantly negatively correlated with changes in these values after HCV eradication, indicating that in patients with high baseline values, the values generally decreased after HCV eradication. Mean small-dense LDL-C (sdLDL-C), which has greater atherogenic potential, was significantly elevated only in patients with both dyslipidemia (LDL-C >140 mg/dL) and liver steatosis (CAP >248 dB/m) at SVR24. Those patients had significant higher baseline BMI, LDL-C, and total-cholesterol levels. Conclusions Generally, successful HCV eradication by IFN-free-DAAs decreases CAP and LDL-C in patients with high baseline values. However, elevated LDL-C was accompanied with elevated sdLDL-C only in patients with liver steatosis and dyslipidemia at SVR24; therefore, those patients may require closer monitoring.

L-Carnitine Suppresses Loss of Skeletal Muscle Mass in Patients With Liver Cirrhosis. Hepatol Commun 2018; 2:906-918. [PMID: 30094402 PMCID: PMC6078216 DOI: 10.1002/hep4.1207] [Citation(s) in RCA: 58] [Impact Index Per Article: 9.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2018] [Revised: 03/18/2018] [Accepted: 05/17/2018] [Indexed: 12/25/2022] Open
Abstract
Liver cirrhosis (LC) is a major cause of secondary sarcopenia. Sarcopenia makes the prognosis worse; thus, novel therapeutic options for sarcopenia in patients with LC are urgently required as they are currently limited. In this retrospective study, 158 patients with LC were screened, and 35 of those patients who were treated with L‐carnitine for more than 6 months and for whom skeletal muscle mass changes could be evaluated by computer tomography were enrolled. Of the 158 patients, 79 patients who did not receive L‐carnitine supplementation served as controls. Cases and controls were propensity score matched for age, sex, presence of hepatocellular carcinoma, and branched chain amino acid administration, and changes in skeletal muscle mass and clinical data were compared. The 35 patients who received L‐carnitine supplementation and 35 propensity score‐matched patients who did not receive carnitine supplementation comprised the final enrollment. Compared with control patients, patients who received L‐carnitine had significantly worse liver function, which is associated with rapid progress of skeletal muscle depletion. However, loss of skeletal muscle mass was significantly suppressed in patients receiving L‐carnitine, and a significant effect was observed in patient subgroups stratified by age, sex, presence of hepatocellular carcinoma, and branched chain amino acid administration. The change ratios of most laboratory data, including vitamin D and insulin‐like growth factor 1 levels, were similar in the two groups, but ammonia levels were significantly less in those receiving L‐carnitine. However, even in patients receiving L‐carnitine but not showing an ammonia decrease, loss of skeletal muscle was significantly suppressed. Conclusion: L‐carnitine suppresses loss of skeletal muscle mass and may therefore be a novel therapeutic option for sarcopenia in patients with LC. (Hepatology Communications 2018; 00:000‐000)

Abstract
Mesenchymal stem cells (MSCs) represent a valuable cell source in regenerative medicine, and large numbers of MSCs can be isolated from the amnion noninvasively. Sclerosing cholangitis is a chronic cholestatic disease and characterized by progressive biliary destruction leading to cirrhosis. Many factors are involved in the development of sclerosing cholangitis; however, effective medical therapy is not established. We investigated the effects of human amnion-derived MSCs (hAMSCs) and conditioned medium (CM) obtained from hAMSC cultures in rats with sclerosing cholangitis. Sclerosing cholangitis was induced via the intragastric administration of 100 mg/kg alpha-naphthylisothiocyanate (ANIT) twice weekly for 4 weeks. One million hAMSCs or 200 μL of CM were intravenously administered on days 15 and 22. Rats were sacrificed on day 29 and evaluated via histological, immunohistochemical, and mRNA expression analyses. hAMSC transplantation and CM administration significantly improved the histological score. In addition, these two interventions significantly improved biliary hyperplasia, peribiliary fibrosis, and inflammation in Glisson's sheath. Accordingly, CK19, MMP-9, and TNF-α, and MCP-1 expression in the liver was also decreased by hAMSC and CM administration. In conclusion, hAMSC and CM administration ameliorated biliary hyperplasia, peribiliary fibrosis, and inflammation in a rat model of sclerosing cholangitis. hAMSCs and CM may represent new modalities for treating sclerosing cholangitis.

Palmitoylethanolamide Ameliorates Carbon Tetrachloride-Induced Liver Fibrosis in Rats. Front Pharmacol 2018; 9:709. [PMID: 30057547 PMCID: PMC6053486 DOI: 10.3389/fphar.2018.00709] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2018] [Accepted: 06/12/2018] [Indexed: 12/12/2022] Open
Abstract
Background: Liver fibrosis is a complex inflammatory and fibrogenic process, and the progression of fibrosis leads to cirrhosis. The only therapeutic approaches are the removal of injurious stimuli and liver transplantation. Therefore, the development of anti-fibrotic therapies is desired. Palmitoylethanolamide (PEA) is an endogenous fatty acid amide belonging to the N-acylethanolamines family and contained in foods such as egg yolks and peanuts. PEA has therapeutic anti-inflammatory, analgesic, and neuroprotective effects. However, the effects and roles of PEA in liver fibrosis remain unknown. Here we investigated the therapeutic effects of PEA in rats with liver fibrosis. Methods: We conducted in vitro experiments to investigate the effects of PEA on the activation of hepatic stellate cells (HSCs, LX-2). Liver fibrosis was induced by an intraperitoneal injection of 1.5 mL/kg of 50% carbon tetrachloride twice a week for 4 weeks. Beginning at 3 weeks, PEA (20 mg/kg) was intraperitoneally injected thrice a week for 2 weeks. Then rats were sacrificed and we performed histological and quantitative reverse-transcription polymerase chain reaction analyses. Results: The expression of α-smooth muscle actin (SMA) induced by transforming growth factor (TGF)-β1 in HSCs was significantly downregulated by PEA. PEA treatment inhibited the TGF-β1-induced phosphorylation of SMAD2 in a dose-dependent manner, and upregulated the expression of SMAD7. The reporter gene assay demonstrated that PEA downregulated the transcriptional activity of the SMAD complex upregulated by TGF-β1. Administration of PEA significantly reduced the fibrotic area, deposition of type I collagen, and activation of HSCs and Kupffer cells in rats with liver fibrosis. Conclusion: Activation of HSCs was significantly decreased by PEA through suppression of the TGF-β1/SMAD signaling pathway. Administration of PEA produced significant improvement in a rat model of liver fibrosis, possibly by inhibiting the activation of HSCs and Kupffer cells. PEA may be a potential new treatment for liver fibrosis.

Safety and efficacy of sofosbuvir and ribavirin for genotype 2 hepatitis C Japanese patients with renal dysfunction. Hepatol Res 2018; 48:529-538. [PMID: 29316051 DOI: 10.1111/hepr.13056] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/07/2017] [Revised: 12/15/2017] [Accepted: 01/04/2018] [Indexed: 12/12/2022]
Abstract
AIM The safety and efficacy of sofosbuvir (SOF) and ribavirin (RBV) have not been well clarified in patients with renal dysfunction because clinical trials have not included such patients. We evaluated the safety and efficacy of SOF and RBV for genotype 2 hepatitis C virus (HCV)-infected patients with renal dysfunction. METHODS The study included genotype 2 HCV-infected patients who received SOF and RBV between July 2014 and May 2017. The sustained virologic response (SVR) after the treatment and safety during the therapy were evaluated according to renal function. RESULTS A total of 231 patients were included in this study. The median age was 62 years old, and 45.9% (106/231) were men. Of the 231 patients, 191 (82.8%) and 40 (17.2%) were classified as having chronic kidney disease (CKD) stages G1/2 and G3, respectively. The overall SVR rate was 97% (224/231). The SVR rates in patients with CKD stages G1, 2, G3a, and G3b were 98.1%, 98.6%, 87.9%, and 100%, respectively, and this therapy was tolerated. Multivariate analysis indicated that renal dysfunction was significantly associated with a non-SVR (odds ratio, 6.963; 95% confidence interval, 1.494-32.41; P = 0.013). The patients with renal dysfunction were older, had advanced liver fibrosis, lower baseline platelet and hemoglobin levels, and a higher rate of RBV dose reduction. CONCLUSIONS Sofosbuvir and RBV therapy is highly effective and safe for genotype 2 HCV-infected Japanese patients. However, attention should be paid to baseline renal function when SOF- and RBV-containing regimens are used for patients with renal dysfunction.

Increased serum C-reactive protein and decreased urinary aquaporin 2 levels are predictive of the efficacy of tolvaptan in patients with liver cirrhosis. Hepatol Res 2018; 48:E311-E319. [PMID: 28984014 DOI: 10.1111/hepr.12988] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/22/2017] [Revised: 09/25/2017] [Accepted: 09/30/2017] [Indexed: 02/08/2023]
Abstract
AIM Water retention, hepatic ascites, and peripheral edema are significant problems in patients with liver cirrhosis (LC). Although furosemide and spironolactone are commonly used as treatment, they are often insufficient to treat hyponatremia and renal insufficiency in patients with LC. Tolvaptan (TVP) could provide an effective treatment alternative. However, predictive factors of a therapeutic response to TVP are unclear. Our aim was to examine clinical predictors of the response to TVP in patients with LC and water retention. METHODS Fifty-two patients were treated with TVP, with therapeutic effects judged by a decrease in body weight (≥2 kg) and increase in urinary volume (≥500 mL) within 7 days. Blood biochemical tests were carried out at baseline and post-treatment, including serum soluble CD14 (sCD14) and urinary aquaporin 2 (AQP2) levels. Clinical and laboratory predictive factors of a TVP response were evaluated by univariate and multivariate analyses. RESULTS The overall response to TVP was 55.8%. On univariate analyses, serum C-reactive protein (CRP) level, the neutrophil-to-lymphocyte ratio, urinary blood urea nitrogen, and urinary AQP2 were predictors of the TVP response, with only serum CRP retained on multivariate analysis. A higher serum sCD14 level was strongly associated with a non-response to TVP. A decrease in urinary AQP2 to undetectable level was associated with a response. CONCLUSION Tolvaptan provides a rapid and strong effect to improve water retention in patients with LC. Baseline serum sCD14 and CRP levels are useful predictors of a response to TVP, with a decrease in urinary AQP2 during treatment indicating an early response.

Add-on effects of fluvastatin in simeprevir/pegylated-interferon/ribavirin combination therapy for patients with genotype 1 hepatitis C virus infection: A randomized controlled study. Hepatol Res 2018; 48:E146-E154. [PMID: 28722780 DOI: 10.1111/hepr.12938] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2017] [Revised: 07/11/2017] [Accepted: 07/12/2017] [Indexed: 02/08/2023]
Abstract
BACKGROUND The Japan Society of Hepatology guidelines indicate that hepatitis C virus (HCV) protease inhibitor combination therapy with simeprevir (SMV), pegylated-interferon (Peg-IFN), and ribavirin (RBV) is a therapeutic option for patients who fail to respond to a direct direct-acting antiviral-containing regimen. However, treatment outcomes have room for improvement. Fluvastatin (FLV) add-on treatment in Peg-IFN and RBV combination therapy for HCV-infected patients significantly improved the sustained virologic response (SVR), but the add-on effect of FLV on SMV combination therapy is not well understood. METHODS This was a prospective, randomized, multicenter study in which a total of 61 HCV genotype 1b-infected patients were recruited and 60 eligible patients were randomly allocated to two groups that received 12 weeks of SMV/Peg-IFN/RBV followed by 12 weeks of Peg-IFN/RBV with or without 24 weeks of FLV. The SVR rate and adverse events were compared between the two groups. RESULTS Thirty-one patients were allocated to the FLV add-on group and 29 patients were allocated to the control group. Baseline clinical factors, including median age, baseline platelet count, alanine aminotransferase level, HCV RNA titer, Fibrosis-4 index, and rate of IL28B minor genotype, were all similar between the two groups. The rapid virologic response, end-of-treatment response rates, SVR rates at 24 weeks after treatment, and safety profiles were also similar between the two groups. CONCLUSIONS This prospective, randomized, multicenter study indicated that FLV had no add-on effect when given with SMV/Peg-IFN/RBV combination therapy for genotype 1b HCV-infected patients.

Abstract
Hepatitis B virus (HBV) reactivation has been reported during antihepatitis C treatment in patients with hepatitis C virus (HCV) and HBV co-infection. We aimed to evaluate the frequency and risk factors of HBV reactivation during anti-HCV therapy and compared those between interferon (IFN)-free direct-acting antiviral (DAA) therapies and IFN-based therapies. Three hundred and twenty-two patients with HCV infection receiving anti-HCV therapy were retrospectively screened. The baseline HBV infection statuses of all eligible patients and the HBV-DNA level of all patients with current or previous HBV infection were examined at the end of treatment. In patients with baseline anti-HBs positivity, changes in anti-HBs titre were evaluated. Of 287 patients who met the inclusion criteria, 157 had current (n=4) or previous (n=153) HBV infection; 85 were treated with IFN-free DAA therapies and 72 were treated with IFN-based therapies. Six patients experienced HBV reactivation (n=2) or HBV reappearance (n=4) after IFN-free DAA therapies, while no patient developed HBV reactivation after IFN-based therapies. The risk factors of HBV reactivation or reappearance were DAA therapies and a reduction in anti-HBs titre to <12 mIU mL-1 by the end of treatment. The decline changes of anti-HBs titre were significantly higher in patients treated with DAA therapies. Although HBV reactivation hepatitis was not observed, three of four patients with HBV reactivation or reappearance after achieving HCV eradication had viremia 8 weeks after completion of therapy. A significant proportion of patients develop HBV reactivation or reappearance without hepatitis after IFN-free DAA therapies. Low levels of anti-HBs and their decrease to <12 mIU mL-1 after treatment are significant risk factors for HBV reactivation or reappearance.
