RESUMO
This study aimed to complement the results of the REACH-2 study by prospectively evaluating the safety and efficacy of ramucirumab in advanced hepatocellular carcinoma (HCC) in a real-world setting. This was an open-label, nonrandomized, multicenter, prospective study conducted at 13 institutions in Japan (jRCTs031190236). The study included Child-Pugh Class A patients with advanced HCC who had received pretreatment with atezolizumab plus bevacizumab (Atez/Bev) or lenvatinib. Ramucirumab was introduced as a second-line treatment after Atez/Bev or lenvatinib and as a third-line treatment after Atez/Bev and lenvatinib. Between May 2020 and July 2022, we enrolled 19 patients, including 17 who received ramucirumab. Additionally, seven patients received lenvatinib, another seven patients received Atez/Bev, and three patients received Atez/Bev followed by lenvatinib as prior treatment. The primary endpoint was a 6-month progression-free survival (PFS) rate, which was 14.3%. The median PFS and overall survival were 3.7 and 12.0 months, respectively. The most common grade ≥ 3 adverse events (AEs) were hypertension (23.5%), proteinuria (17.6%), and neutropenia (11.8%). The discontinuation rate due to AEs was 29.4%. Six patients progressed from Child-Pugh A to B after treatment with ramucirumab. Thirteen patients were eligible for post-ramucirumab treatment, including systemic therapy. Despite the limited number of patients, the efficacy of ramucirumab was comparable to that observed in the REACH-2 study when used after lenvatinib and Atez/Bev. However, the incidence of AEs was higher than that in the REACH-2 study.

BACKGROUND AND AIMS: This study aimed to determine the safety and efficacy of atezolizumab + bevacizumab therapy in hepatocellular carcinoma patients receiving anti-platelet agents or anticoagulants. METHODS: Patients were divided into those using (IM out) and those not using (IM in) anti-platelet agents or anticoagulants, who violated the exclusion criteria of the IMbrave150 trial, and were retrospectively examined. RESULTS: The study included 185 patients (IM in: 157; IM out: 28). For first-line treatment, progression-free survival was 184 days for IM in and 266 days for IM out (p = .136). Overall survival was 603 days for IM in and not reached for IM out (p = .265), with no significant between-group difference. Similarly, there were no significant between-group differences in progression-free survival or overall survival for later-line treatment. Haemorrhagic adverse events of ≥grade 3 were observed in 11 IM in patients and 3 IM out patients. No significant factors associated with haemorrhagic adverse events of ≥grade 3 were identified in the multivariate analysis including IM out classification, whose p value was .547. Regarding thrombotic/embolic adverse events in the IM out group, one case of exacerbation of portal vein thrombosis was observed. No deaths were directly attributable to bleeding events or exacerbations of thrombosis. CONCLUSION: Atezolizumab + bevacizumab therapy shows similar safety and efficacy in patients receiving and those not receiving anti-platelet agents or anticoagulants; therefore, it can be considered for patients with hepatocellular carcinoma receiving anti-platelet agents or anticoagulants.

BACKGROUND AND AIM: The aim of this study was to develop a novel noninvasive test using an artificial intelligence/neural network system (called HCC-Scope) to diagnose early-stage hepatocellular carcinoma (HCC) on the background of nonalcoholic steatohepatitis (NASH). METHODS: In total, 175 patients with histologically proven nonalcoholic fatty liver disease and 55 patients with NASH-HCC were enrolled for training and validation studies. Of the 55 patients with NASH-HCC, 27 (49.1%) had very early-stage HCC, and six (10.9%) had early-stage HCC based on the Barcelona Clinic Liver Cancer staging system. Diagnosis with HCC-Scope was performed based on 12 items: age, sex, height, weight, AST level, ALT level, gamma-glutamyl transferase level, cholesterol level, triglyceride level, platelet count, diabetes status, and IgM-free apoptosis inhibitor of macrophage level. The FMVWG2U47 hardware (Fujitsu Co. Ltd, Tokyo, Japan) and the originally developed software were used. RESULTS: HCC-Scope had sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of 100% for the differential diagnosis between non-HCC and HCC in a training study with gray zone analysis. It was also excellent in the validation study (95.0% sensitivity, 100% specificity, 100% PPV, and 97.1% NPV with gray zone analysis and 95.2% sensitivity, 100% specificity, 100% PPV, and 97.1% NPV without gray zone analysis). HCC-Scope had a significantly higher sensitivity (85.3%) and specificity (85.1%) than alpha-fetoprotein (AFP) level, AFP-L3 level, des-gamma-carboxy prothrombin (DCP) level, and the gender-age-AFP-L3-AFP-DCP (GALAD) score. CONCLUSIONS: HCC-Scope can accurately differentially diagnose between non-HCC NASH and NASH-HCC, including very early-stage NASH-HCC.
RESUMO
BACKGROUND AND AIM: Pemafibrate, a selective peroxisome proliferator activated receptor α modulator, has been shown to improve liver function among nonalcoholic fatty liver disease (NAFLD) patients with dyslipidemia. The aim of this retrospective study is to identify predictors of pemafibrate efficacy in NAFLD patients. METHODS: A total of 75 NAFLD patients with dyslipidemia who received pemafibrate twice per day for 48 weeks were enrolled in this study. We used the FibroScan-aspartate aminotransferase (FAST) score as a benchmark for treatment efficacy. RESULTS: Median FAST score significantly decreased from 0.96 at baseline to 0.93 at week 48 (P < 0.001). Significant improvements in levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transferase (GGT), and triglycerides were also noted. The serum level of GGT at baseline was correlated with change in FAST score (r = -0.22, P = 0.049). Changes in AST, ALT, and GGT were positively correlated with change in FAST score (r = 0.71, r = 0.61, and r = 0.38). Multivariate analyses identified age and GGT level at baseline as significantly associated with improvement of FAST score by pemafibrate therapy (odds ratio 1.11, 1.02, respectively). Patients over 50 years of age and with a GGT of 90 IU/L or higher showed significantly greater improvement in the FAST score than other groups. CONCLUSIONS: Pemafibrate improves the FAST score of NAFLD patients with complicating dyslipidemia, especially in older patients with high GGT level. GGT is useful as an indicator of optimal treatment choice for NAFLD patients with dyslipidemia.

Fibroblast growth factor (FGF) 21 is an endocrine growth factor mainly secreted by the liver in response to a ketogenic diet and alcohol consumption. FGF21 signaling requires co-receptor ß-klotho (KLB) co-acting with FGF receptors, which has pleiotropic metabolic effects, including induced hepatic fatty acid oxidation and ketogenesis, in human and animal models of obesity. We examined the hepatocyte-specific enhancer/promoter of FGF21 expression plasmids in high-fat diet-fed mice for 12 weeks. Hydrodynamic injection for FGF21 delivery every 6 weeks sustained high circulating levels of FGF21, resulting in marked reductions in body weight, epididymal fat mass, insulin resistance, and liver steatosis. FGF21-induced lipolysis in the adipose tissue enabled the liver to be flooded with fat-derived FFAs. The hepatic expression of Glut2 and Bdh1 was upregulated, whereas that of gluconeogenesis-related genes, G6p and Pepck, and lipogenesis-related genes, Srebp-1 and Srebp-2, was significantly suppressed. FGF21 induced the phosphorylation of AMPK at Thr172 and Raptor at ser792 and suppressed that of mTOR at ser2448, which downregulated mTORC1 signaling and reduced IRS-1 phosphorylation at ser1101. Finally, in the skeletal muscle, FGF21 increased Glut4 and Mct2, a membrane protein that acts as a carrier for ketone bodies. Enzymes for ketone body catabolism (Scot) and citrate cycle (Cs, Idh3a), and a marker of regenerating muscle (myogenin) were also upregulated via increased KLB expression. Thus, FGF21-induced lipolysis was continuously induced by a high-fat diet and fat-derived FFAs might cause liver damage. Hepatic fatty acid oxidation and ketone body synthesis may act as hepatic FFAs' disposal mechanisms and contribute to improved liver steatosis. Liver-derived ketone bodies might be used for energy in the skeletal muscle. The potential FGF21-related crosstalk between the liver and extraliver organs is a promising strategy to prevent and treat metabolic syndrome-related nonalcoholic steatohepatitis.

BACKGROUND: The apoptosis inhibitor of macrophage (AIM) is usually associated with the immunoglobulin M (IgM) pentamer in the blood and is dissociated from IgM in various diseases, including hepatocellular carcinoma (HCC) in nonalcoholic steatohepatitis (NASH). We aimed to elucidate whether IgM-free AIM (fAIM) is useful for detecting latent HCC in NASH. METHODS: This research consisted of two cohort studies. The levels of serum fAIM, alpha-fetoprotein (AFP), and des-gamma carboxy prothrombin (DCP) of 18 NASH patients who developed HCC were measured during the follow-up period before HCC diagnosis (median, 4.7 years). In total, 199 patients with nonalcoholic fatty liver disease (NAFLD) were included in the HCC survey. The serum fAIM levels were analyzed using enzyme-linked immunosorbent assays. RESULTS: In the cohort of 18 patients with HCC, 12 had high fAIM at the time of the initial blood sample, three had normal fAIM levels throughout the follow-up period, and three had fAIM elevated from normal to positive. The positive ratio of fAIM prior to HCC diagnosis remained significantly higher than that of AFP and DCP, and the fAIM ratio gradually increased. In a survey of 199 non-HCC NAFLD patients, a Cox regression analysis using independent variables, such as AFP, fAIM, age, albumin, bilirubin, and fibrosis stage, revealed that fAIM and AFP were significantly associated with the incidence of HCC. CONCLUSIONS: During the development of NASH-HCC, AIM activation in blood appears to start even before HCC is diagnostically detectable. Thus, the serum IgM-free AIM levels could be a new, sensitive biomarker for latent NASH-HCC.
RESUMO
AIM: There is insufficient evidence regarding the safety and efficacy of molecular targeted agents (MTAs) for elderly patients with hepatocellular carcinoma (HCC), who are likely to be vulnerable to adverse events (AEs) of therapy. The aim of this study was to compare sorafenib and lenvatinib use in elderly patients with HCC from the viewpoint of overall survival (OS) and rate of AE-induced MTA discontinuation. METHODS: This retrospective study included patients with HCC over 80 years old who received first-line molecular targeted therapy (MTT) at four hospitals between June 2009 and September 2019. They were divided into three groups according to the era and type of first-line MTA: E1-Sora (sorafenib, between 2009 and 2016), E2-Sora (sorafenib, between 2017 and 2019), and E2-Len (lenvatinib, between 2017 and 2019). RESULTS: The study included 173 patients (E1-Sora, n = 79; E2-Sora, n = 50; E2-Len, n = 44) with a median age of 81.9 years (range, 80-93 years). Median OS was 15.1 months in the entire cohort (E1-Sora, 12.7 months; E2-Sora, 20.5 months; E2-Len, 10.3 months). The rate of treatment discontinuation due to AEs was high in the entire cohort, especially in E1-Sora and E2-Len (49.4% in E1-Sora, 28.0% in E2-Sora, and 54.6% in E2-Len, p = 0.0753). More E2-Sora patients received subsequent MTT than E2-Len patients (E2-Sora, 50%; E2-Len, 28.6%; p = 0.0111). CONCLUSION: Both sorafenib and lenvatinib were effective and feasible for elderly patients with HCC. In terms of discontinuation due to AEs and subsequent MTT, sorafenib might be more desirable for elderly patients with HCC over 80 years.
RESUMO
Chronic liver injury may result in hepatic fibrosis, which can progress to cirrhosis and eventually liver failure. There are no drugs that are specifically approved for treating hepatic fibrosis. The natural product honokiol (HNK), a bioactive compound extracted from Magnolia grandiflora, represents a potential tool in the management of hepatic fibrosis. Though HNK has been reported to exhibit suppressive effects in a rat fibrosis model, the mechanisms accounting for this suppression remain unclear. In the present study, the anti-fibrotic effects of HNK on the liver were evaluated in vivo and in vitro. In vivo studies utilized a murine liver fibrosis model, in which fibrosis is induced by treatment with carbon tetrachloride (CCl4). For in vitro studies, LX-2 human hepatic stellate cells (HSCs) were treated with HNK, and expression of markers of fibrosis, cell viability, the transforming growth factor-ß (TGF-ß1)/SMAD signaling pathway, and autophagy were analyzed. HNK was well tolerated and significantly attenuated CCl4-induced liver fibrosis in vivo. Moreover, HNK decreased HSC activation and collagen expression by downregulating the TGF-ß1/SMAD signaling pathway and autophagy. These results suggest that HNK is a new potential candidate for the treatment of hepatic fibrosis through suppressing both TGF-ß1/SMAD signaling and autophagy in HSCs.

A previous randomized phase 2 study of hepatocellular carcinoma revealed that the c-Met inhibitor tivantinib as second-line treatment significantly prolonged progression-free survival in a subpopulation whose tumor samples highly expressed c-Met (MET-high). Accordingly, this phase 3 study was conducted to evaluate the efficacy of tivantinib as a second-line treatment for Japanese patients with MET-high hepatocellular carcinoma. This randomized, double-blind, placebo-controlled study was conducted at 60 centers in Japan. Hepatocellular carcinoma patients with one prior sorafenib treatment and those with MET-high tumor samples were eligible for inclusion. Registered patients were randomly assigned to either the tivantinib or placebo group at a 2:1 ratio and were treated with twice-a-day oral tivantinib (120 mg bid) or placebo until the discontinuation criteria were met. The primary endpoint was progression-free survival while the secondary endpoints included overall survival and safety. Between January 2014 and June 2016, 386 patients provided consent, and 195 patients were randomized to the tivantinib (n = 134) or placebo (n = 61) group. Median progression-free survival was 2.8 (95% confidence interval: 2.7-2.9) and 2.3 (1.5-2.8) mo in the tivantinib and placebo groups, respectively (hazard ratio = 0.74, 95% confidence interval: 0.52-1.04, P = .082). Median overall survival was 10.3 (95% confidence interval: 8.1-11.6) and 8.5 (6.2-11.4) mo in the tivantinib and placebo group, respectively (hazard ratio = 0.82, 95% confidence interval: 0.58-1.15). The most common tivantinib-related grade ≥3 adverse events were neutropenia (31.6%), leukocytopenia (24.8%), and anemia (12.0%). This study did not confirm the significant efficacy of tivantinib as a second-line treatment for Japanese patients with MET-high hepatocellular carcinoma. (NCT02029157).

BACKGROUND & AIMS: PNPLA3 rs738409 has been associated with increased risks of fibrosis in patients with non-alcoholic fatty liver disease (NAFLD). Recently, carriage of the rs6834314 G allele, which is in high linkage with rs72613567 of 17-beta-hydroxysteroid dehydrogenase 13 (HSD17B13), was reported to be associated with a reduced risk of liver injury in NAFLD patients. We estimated the impact of these genetic variants on hepatic fibrosis in Japanese patients with NAFLD. METHODS: We analysed the associations of these genetic variants with liver histology in 290 Japanese patients with biopsy-proven NAFLD diagnosed during 2002-2019. During follow-up, 14 patients (4.8%) developed hepatocellular carcinoma. RESULTS: Prevalences of the PNPLA3 rs738409 genotypes were 0.17 for CC, 0.41 for CG, 0.42 for GG, and those for HSD17B13 rs6834314 were 0.54 for AA, 0.39 for AG and 0.07 for GG. There was no significant interaction between the PNPLA3 and HSD17B13 genotypes. Prevalences of advanced fibrosis according to PNPLA3/HSD17B13 genotypes were 0.16 for CC,CG/AG,GG, 0.20 for CC,CG/AA, 0.30 for GG/AG,GG and 0.37 for GG/AA. Multivariate analysis identified PNPLA3 GG as a predictor of advanced fibrosis (stage 3/4) in carriers of HSD17B13 AA (odds ratio 2.4, P = .041), but not HSD17B13 AG/GG (P = .776). The HSD17B13 genotype G was significantly associated with lower prevalences of severe inflammation and ballooning and tended to be associated with a higher prevalence of advanced steatosis. CONCLUSIONS: In Japanese patients with NAFLD, carriage of the HSD17B13 rs6834314 G allele attenuated the effect of the PNPLA3 rs738409 GG genotype on advanced hepatic fibrosis.

AIM: Dyslipidemia (DL) is commonly associated with non-alcoholic fatty liver disease (NAFLD). Pemafibrate, a selective peroxisome proliferator activated receptor α modulator (SPPARMα), has been shown to improve liver function among patients with DL. The aim of this single-arm prospective study is to evaluate the efficacy of pemafibrate in NAFLD patients with DL. METHODS: Twenty NAFLD patients with DL who received pemafibrate (0.1 mg) twice a day for 12 weeks were prospectively enrolled in this study. The primary end-point was change in serum alanine aminotransferase (ALT) levels from baseline to week 12. RESULTS: Serum ALT levels decreased from 75.1 IU/L at baseline to 43.6 IU/L at week 12 (P = 0.001). Significant improvements in triglyceride, high-density lipoprotein cholesterol, total fatty acid, saturated fatty acid (SFA), and unsaturated fatty acid were also noted. The serum level of remnant-like protein cholesterol, SFA, and polyunsaturated / saturated fatty acid ratio (PUFA / SFA ratio) at baseline were correlated with change in ALT level (r = -0.53, r = -0.57, and r = 0.46, respectively). Change in PUFA and change in PUFA / SFA ratio were negatively correlated with change in ALT level (r = -0.49 and r = -0.53). No hepatic or renal adverse events were reported. CONCLUSIONS: Selective peroxisome proliferator activated receptor α could be a promising novel agent for treatment of NAFLD patients with DL by regulating fatty acid composition. A further long-term large-scale trial is warranted to confirm the efficacy of SPPARMα on NAFLD with DL.
RESUMO
AIM: Recently, FibroScan-AST (FAST) score was reported to be effective for identifying non-alcoholic steatohepatitis (NASH) with significant activity and fibrosis in non-alcoholic fatty liver disease (NAFLD). The aim of this study was to confirm the diagnostic accuracy of FAST score of Japanese patients and compare the cut-off values and diagnostic accuracy between the FibroScan M and XL probes. METHODS: Eighty-two and 84 patients were included the verification and validation sets, respectively. All patients were diagnosed with NAFLD by biopsy by two central expert pathologists. Liver stiffness measurements and controlled attenuation parameter were carried out, and diagnostic performance was evaluated using receiver operating characteristic (ROC) curve analysis. RESULTS: No significant difference existed in FAST score between the M and XL probes (0.489 vs. 0.483, P = 0.187). No significant difference existed in the area under the ROC between the two probes (M, 0.7598; XL, 0.7614; P = 0.958). According to the Youden index, the cut-off value using the M probe was 0.57 with 68.2% sensitivity and 78.3% specificity. For the XL probe, the cut-off value was 0.56 with 68.2% sensitivity and 73.3% specificity. To obtain sensitivity and specificity values higher than 90%, cut-off values of 0.35 and 0.66 were chosen for the M probe and 0.32 and 0.63 were chosen for the XL probe. CONCLUSIONS: There was no significant difference in diagnostic accuracy of FAST score between the FibroScan M and XL probes. The FAST score can be used to identify NASH with significant risk in Japanese patients regardless of probe selection.
RESUMO
BACKGROUND: A randomized, controlled trial to evaluate the superiority of percutaneous transesophageal gastro-tubing over nasogastric tubing as palliative care for bowel obstruction in patients with terminal malignancy was conducted. SUBJECTS AND METHODS: The subjects were patients with malignant bowel obstruction with no prospect of improvement, for whom surgery was not indicated and with a Palliative Prognostic Index of < 6. They were randomly allocated in a 1:1 ratio to receive either percutaneous transesophageal gastro-tubing (PTEG group) or nasogastric tubing (NGT group). Their symptom scores (the worst 0 to no symptoms 10) were measured for a 2-week period after enrollment, and the areas under the curves for the two groups were compared. The EQ-5D and SF-8 were also used to assess overall quality of life. RESULTS: Forty patients were enrolled between October 2009 and January 2015, with 21 allocated to the PTEG group and 19 to the NGT group. The mean areas under the curves (95% confidence intervals) for the PTEG group and the NGT groups were 149.6 (120.3-178.8) and 44.9 (16.4-73.5), respectively, significantly higher for the NGT group (p < 0.0001). The secondary endpoints of quality of life as assessed by the EQ-5D and SF-8 scores were also significantly higher for patients in the PTEG group (p = 0.0036, p = 0.0020). There was no difference in survival between the groups. No serious adverse events were observed. CONCLUSIONS: In terms of quality of life, percutaneous transesophageal gastro-tubing was superior to nasogastric tubing as palliative care for patients with bowel obstruction due to terminal malignancy.

BACKGROUND & AIMS: Nivolumab, an immune checkpoint inhibitor, is approved in several countries to treat sorafenib-experienced patients with HCC, based on results from the CheckMate 040 study (NCT01658878). Marked differences exist in HCC clinical presentation, aetiology, treatment patterns and outcomes across regions. This analysis assessed the safety and efficacy of nivolumab in the Asian cohort of CheckMate 040. METHODS: CheckMate 040 is an international, multicentre, open-label, phase I/II study of nivolumab in adults with advanced HCC, regardless of aetiology, not amenable to curative resection or local treatment and with/without previous sorafenib treatment. This analysis included all sorafenib-experienced patients in the intent-to-treat (ITT) overall population and Asian cohort. The analysis cut-off date was March 2018. RESULTS: There were 182 and 85 patients in the ITT population and Asian cohort, respectively. In both populations, most patients were older than 60â¯years, had BCLC (Barcelona Clinic Liver Cancer) Stage C disease, and had received previous systemic therapy. A higher percentage of Asian patients had HBV infections, extrahepatic metastases and prior therapies. Median follow-up was 31.6 and 31.3â¯months for the ITT and Asian patients, respectively. Objective response rates were 14% and 15% in the ITT population and Asian cohort, respectively. In the Asian cohort, patients with HBV, HCV or those who were uninfected had objective response rates of 13%, 14% and 21%, respectively. The median duration of response was longer in the ITT (19.4â¯months) vs. Asian patients (9.7â¯months). Median overall survival was similar between the ITT (15.1â¯months) and Asian patients (14.9â¯months), and unaffected by aetiology in Asian patients. The nivolumab safety profile was similar and manageable across both populations. CONCLUSION: Nivolumab safety and efficacy are comparable between sorafenib-experienced ITT and Asian patients. LAY SUMMARY: The CheckMate 040 study evaluated the safety and efficacy of nivolumab in patients with advanced hepatocellular carcinoma who were refractory to previous sorafenib treatment or chemotherapy. This subanalysis of the data showed that treatment responses and safety in patients in Asia were similar to those of the overall treatment population, providing support for nivolumab as a treatment option for these patients. Clinical trial number: NCT01658878.

BACKGROUND: Sarcopenia is diagnosed with the skeletal muscle index (SMI) or the sarcopenia index (SI). We previously reported that the ratio of skeletal muscle mass to body fat mass (SF ratio) was a novel index of sarcopenia in patients with non-alcoholic fatty liver disease (NAFLD). The aim of this retrospective study was to evaluate sarcopenia with these indices in patients with NAFLD. METHODS: One hundred and fifty-six consecutive patients with biopsy-proven NAFLD and alanine aminotransferase (ALT) >40 IU/L were enrolled. Liver function and body composition were evaluated in 121 patients after 12 months. We evaluated the relationship between histological findings, changes in liver function, and the SMI, SI, and SF ratio. RESULTS: Of the 156 patients enrolled, 13.5% and 26.3% were diagnosed with sarcopenia with the SMI and SI. In patients with hepatic fibrosis stage <2, the SI and the SF ratio were significantly greater than in patients with fibrosis stage ≥2. There was no difference in SMI between groups. In the cohort assessed at baseline and 12 months later, transaminase activity and SMI decreased significantly, and the SF ratio increased over time. A multivariate analysis revealed the presence of the PNPLA3 G allele and an increase in SF ratio (odds ratio, 7.406) as predictive factors of ALT reduction >30% from baseline. CONCLUSIONS: Due to the high prevalence of obesity, we should consider both skeletal muscle mass and body fat mass in the diagnosis and treatment of NAFLD. The SF ratio could be a useful index in sarcopenic NAFLD.
RESUMO
AIMS: The liver function of patients with hepatitis C virus (HCV) infection who obtained sustained virologic response (SVR) has been known to improve after HCV eradication. However, a predictor of liver function after SVR has not been definitively identified. The aim of this retrospective study was to identify a predictor of deteriorated liver function and Fibrosis-4 (FIB-4) index after SVR was achieved by direct-acting antiviral (DAA) treatment. METHODS: This study retrospectively enrolled 248 patients who obtained SVR by DAA treatment. None of the patients developed hepatocellular carcinoma during this study. Liver function was assessed at the end of treatment (EOT) and at 24, 48, 72, and 96 weeks after EOT. RESULTS: At 96 weeks after EOT, the serum aspartate aminotransferase and alanine aminotransferase levels were significantly decreased from those at EOT. The platelet count was significantly increased from 14.9 × 104 /µL at EOT to 17.1 × 104 /µL at 96 weeks after EOT. Ten patients showed an increased FIB-4 (>1.00) index. Multivariate analysis with 171 patients who underwent endoscopic assessment revealed that the presence of varices was an independent predictor of deterioration in the FIB-4 index (odds ratio, 5.56; P = 0.041). CONCLUSION: Most of the study patients who obtained SVR showed improved liver function after EOT. Patients without increasing platelet counts after SVR due to DAA therapy should be evaluated for complications induced by portal hypertension.
RESUMO
Non-alcoholic fatty liver disease (NAFLD) is associated with chronic kidney disease (CKD). The aim of this retrospective study was to determine the risk factors for progression of CKD in patients with biopsy-proven NAFLD including patatin-like phospholipase domain containing 3 (PNPLA3) polymorphism. A total of 344 patients with biopsy-proven NAFLD were enrolled consecutively in this study. Multivariate analysis identified males (odds ratio (OR) 5.46), age (per 1 year, OR 1.07), and FIB-4 index (≥1.30, OR 3.85) as factors associated with CKD. Of the 154 patients with a baseline estimated glomerular filtration rate (eGFR) ≥60 mL/min, 30 had a deterioration in CKD stage and 15 developed CKD after 3 years. Multivariate analysis identified diabetes mellitus (OR 2.44) as a risk factor for deterioration in CKD stage, while diabetes mellitus (OR 21.54) and baseline eGFR (per 1 mL/min OR 0.88) were risk factors for development of CKD. PNPLA3 did not affect the change in eGFR. In NAFLD patients, a high FIB-4 index was associated with CKD to increases in the index linked to reductions in eGFR. In order to prevent development of CKD, an appropriate therapy focusing on renal function is needed for NAFLD patients, especially those with diabetes.

We conducted a multicenter retrospective analysis to evaluate the efficacy of systemic chemotherapy for unresectable combined hepatocellular and cholangiocarcinoma. We enrolled 36 patients with pathologically proven, unresectable combined hepatocellular and cholangiocarcinoma treated with systemic chemotherapy. The log-rank test determined the significance of each prognostic factor. Elevated alpha-fetoprotein, carcinoembryonic antigen and carbohydrate antigen 19-9 levels were observed in 58.3%, 16.7% and 38.9% of patients, respectively. First-line chemotherapy included platinum-containing regimens consisting of gemcitabine/cisplatin (n = 12) and fluorouracil/cisplatin (n = 11), sorafenib (n = 5) and others (n = 8). The median overall and progression-free survival times were 8.9 and 2.8 months, respectively, with an overall response rate of 5.6%. Prognostic factors associated with negative outcomes included poor performance status, no prior primary tumor resection, a Child-Pugh class of B, and elevated carcinoembryonic antigen levels with a hazard ratio of 2.25, 2.48, 3.25 and 2.84 by univariate analysis, respectively. The median overall survival times of the gemcitabine/cisplatin, fluorouracil/cisplatin, sorafenib and other groups were 11.9, 10.2, 3.5 and 8.1 months, respectively. Multivariate analysis revealed that the overall survival of patients within the sorafenib monotherapy group was poor compared with platinum-containing regimens (HR: 15.83 [95% CI: 2.25-111.43], P = .006). All 7 patients in the sorafenib group had progressive disease, including 2 patients with second-line therapy. In conclusion, the platinum-containing regimens such as gemcitabine/cisplatin were associated with more favorable outcomes than sorafenib monotherapy for unresectable combined hepatocellular and cholangiocarcinoma.

AIM: In Japan, transcatheter arterial chemoembolization (TACE) refractoriness for hepatocellular carcinoma has been defined as an insufficient therapeutic effect after ≥2 procedures. Insufficient TACE for intrahepatic lesions is defined as the presence of > 50% viable lesions (ineffective) or an increase in their number (progressive). This study aimed to examine the possibility of earlier evaluation of TACE refractoriness. METHODS: Patients who underwent TACE for hepatocellular carcinomas > 3 cm in size or with > 3 nodules at our hospital between 2010 and 2014 were analyzed. The cases assessed as TACE insufficient for the first time were divided into 2 groups: the "either" group, evaluated as either "ineffective" or "progressive," and the "both" group, that is, both "ineffective" and "progressive." RESULTS: The study participants included 40 of 212 consecutive patients who underwent TACE, divided into the either (n = 23) and both (n = 17) groups. Seventeen of 23 (73.9%) patients in the either group and all 17 (100%) in the both group had TACE refractoriness (p = 0.0295). CONCLUSIONS: Patients with both "ineffective" and "progressive" lesions are extremely likely to be TACE -refractory at a significantly higher frequency than are those with either condition. Thus, when both of these factors are observed, switching to other therapies should be considered.

AIM: Type 2 diabetes mellitus (T2DM) is a major complication of patients with non-alcoholic fatty liver disease (NAFLD). The aim of this retrospective study is to determine the risk factors for development of T2DM in patients with biopsy-proven NAFLD. METHODS: One hundred and sixty two consecutive patients with biopsy-proven NAFLD who received a 75-g oral glucose tolerance test were enrolled as the total cohort. Among them, we analyzed 89 patients without T2DM diagnosed by oral glucose tolerance test to estimate the cumulative rate for development of T2DM as the follow-up cohort. RESULTS: Of 162 patients, the glucose tolerance pattern were DM in 45 patients (27.8%), impaired glucose tolerance in 68 (42.0%), and normal glucose tolerance in 49 (30.2%). Patients with NAFL tended to be more likely to have normal glucose tolerance than those with non-alcoholic steatohepatitis (NASH). The serum levels of pre- and post-load insulin were significantly higher in the NASH group. Of 89 patients without T2DM, 13 patients newly developed T2DM during a follow-up period of 5.2 years. The cumulative rate of T2DM incidence was 8.8% at the end of the 5th year and 23.4% at the end of the 10th year. Multivariate analysis identified homeostasis model of assessment - insulin resistance (≥3.85, hazard ratio 40.1, P = 0.033) as an independent risk factor for development of T2DM. CONCLUSIONS: Patients with NASH have an underlying potential of glucose intolerance. In NAFLD patients, insulin resistance is the most important risk factor for the incidence of T2DM. Appropriate therapy against insulin resistance could be needed for patients with NAFLD to prevent development of T2DM.
