RESUMEN
The number of patients with fatty liver has been increasing worldwide; however, the significance of fatty liver in patients with chronic hepatitis B who are receiving nucleic acid analog (NA) therapy remains unclear. Thus, we aimed to determine whether fatty liver affects the development of hepatocellular carcinoma (HCC) in patients receiving NA therapy. This study included 445 patients who received NA therapy, and the development of HCC was investigated. The primary outcome was the association between fatty liver and HCC development. During a mean follow-up period of 7.4 years, 46 patients (10.3%) developed HCC. No significant difference in the cumulative incidence of HCC was observed between patients with fatty liver and those without (p = 0.17). Multivariable analysis for age, gender, platelet count, alanine aminotransferase level at 1 year following NA therapy, and fatty liver revealed that the presence of fatty liver was not a significant factor for HCC development (hazard ratio [HR]: 0.96, 95% confidence interval [CI]: 0.5-1.9). In another multivariable analysis for advanced fibrosis, gender, and fatty liver, advanced fibrosis was found to be a significant factor for HCC development (HR: 9.50, 95% CI: 5.1-18) but not fatty liver (HR: 0.90, 95% CI: 0.5-1.7). In conclusion, in patients with chronic hepatitis B who received NA therapy, advanced fibrosis was found to be an important risk factor for HCC development but not fatty liver, suggesting the importance of providing treatment before the progression of liver fibrosis regardless of the presence of fatty liver.

BACKGROUND: Patients with nonalcoholic fatty liver disease (NAFLD) are highly at risk for cardiovascular disease (CVD). However, the risk of developing CVD in patients with lean NAFLD is not yet fully understood. Therefore, this study aimed to compare the CVD incidence in Japanese patients with lean NAFLD and those with non-lean NAFLD. METHODS: A total of 581 patients with NAFLD (219 with lean and 362 with non-lean NAFLD) were recruited. All patients underwent annual health checkups for at least 3 years, and CVD incidence was investigated during follow-up. The primary end-point was CVD incidence at 3 years. RESULTS: The 3-year new CVD incidence rates in patients with lean and non-lean NAFLD were 2.3% and 3.9%, respectively, and there was no significant difference between two groups (p = 0.3). Multivariable analysis adjusted for age, sex, hypertension, diabetes, and lean NAFLD/non-lean NAFLD revealed that age (every 10 years) as an independent factor associated with CVD incidence with an odds ratio (OR) of 2.0 (95% confidence interval [CI]: 1.3-3.4), whereas lean NAFLD was not associated with CVD incidence (OR: 0.6; 95% CI: 0.2-1.9). CONCLUSIONS: CVD incidence was comparable between patients with lean NAFLD and those with non-lean NAFLD. Therefore, CVD prevention is needed even in patients with lean NAFLD.

AIM: Alanine aminotransferase (ALT) is a criterion for the introduction of nucleotide/nucleoside analog (NA), and ALT levels are decreased by NA treatment. However, the association between post-treatment ALT levels and hepatocellular carcinoma (HCC) risk remains unclear. To fill this gap, we aimed to establish a target value of ALT level during NA treatment. METHODS: In total, 413 patients with chronic hepatitis B who received entecavir, tenofovir alafenamide, or tenofovir disoproxil fumarate were enrolled. The subsequent development of HCC was examined and a target value of ALT level during NA treatment as a risk marker for HCC was evaluated. RESULTS: The median follow-up duration was 5.1 years, during which time 27 patients (8.6%) developed HCC. ALT level at the start of treatment was not associated with HCC development (p = 0.08). When stratified by ALT at 1 year after NA initiation, the cumulative 3- and 5-year rates of HCC for patients with ALT ≥21 IU/L were 11.5% and 18.1%, and those with ALT <21 IU/L was 2.3% and 6.5%, respectively. Patients with ALT <21 IU/L had a significantly lower risk of HCC development compared with patients with ALT ≥21 IU/L (p = 0.002). In multivariable analysis adjusting age, sex, and platelet counts, ALT ≥21 IU/L was an independent risk factor of HCC development with hazard ratio of 4.5 (95% confidence interval: 1.01-20.4). CONCLUSIONS: ALT <21 IU/L at 1 year after NA initiation has a lower risk of HCC and could be used as a target value for NA treatment.
RESUMEN
BACKGROUND: We aimed to investigate the efficacy and safety of atezolizumab plus bevacizumab therapy in patients with unresectable hepatocellular carcinoma (u-HCC) based on whether they had previously received systemic therapy, as well as the association of atezolizumab plus bevacizumab with early alpha-fetoprotein (AFP) response in real-world practice. METHODS: A total of 52 patients with u-HCC were treated with atezolizumab plus bevacizumab between October 2020 and April 2021. The Response Evaluation Criteria in Solid Tumors (RECIST) and modified RECIST were used to evaluate radiological responses. RESULTS: The patients received atezolizumab plus bevacizumab as 1st-line (n = 23), 2nd-line (n = 16), 3rd-line (n = 6), 4th-line (n = 3), 5th-line (n = 3), or 6th-line (n = 1) therapy. According to RECIST, the objective response rate (ORR) and disease control rate (DCR) in all patients were 15.4% and 57.7%. In the 1st-line patients, ORR and DCR based on RECIST 1.1 were 27.3% and 81.8%. The median time to progression (TTP) assessed by RECIST was significantly longer among patients receiving atezolizumab plus bevacizumab as 1st-line therapy than in patients receiving atezolizumab plus bevacizumab as later-line therapy (P < 0.001). Patients with an AFP response (reduction ≥ 20% from baseline) at 6 weeks had a significantly longer TTP assessed by RECIST than those without an AFP response (P = 0.02). CONCLUSION: Patients who received atezolizumab plus bevacizumab as 1st-line therapy had better clinical outcome than those who received atezolizumab plus bevacizumab in later lines. The AFP response at 6 weeks could be a predictor of disease progression.

Objective Rifaximin is used to treat hepatic encephalopathy. However, whether or not rifaximin and lactulose combination therapy can enhance the treatment outcomes and reduce the hospitalization rate of patients with hepatic encephalopathy that are resistant to lactulose has yet to be determined. The present study investigated the hospitalization rate before and after rifaximin add-on therapy in patients resistant to lactulose. Methods A total of 36 patients who were resistant to lactulose with add-on rifaximin therapy were enrolled. Patients who were hospitalized and/or did not achieve normalization of ammonia levels under lactulose administration were defined as treatment-resistant. The primary outcome was the change in hospitalization rate due to hepatic encephalopathy at 24 weeks before and after rifaximin administration. Results Before rifaximin administration, 15 (41.6%) patients were hospitalized due to hepatic encephalopathy. After rifaximin administration, 8 (22.2%) patients were hospitalized due to hepatic encephalopathy. The hospitalization rates were significantly reduced after rifaximin administration (p=0.02). The median (interquartile range) ammonia levels upon rifaximin administration (baseline) and 8, 12, and 24 weeks after rifaximin administration were 124 (24-310) µg/dL, 78 (15-192) µg/dL, 67 (21-233) µg/dL, and 77 (28-200) µg/dL, respectively. Furthermore, the ammonia levels were significantly reduced by rifaximin add-on therapy (p=0.005, p=0.01, and p=0.01). Conclusion The addition of rifaximin to lactulose treatment in treatment-resistant patients decreases the hospitalization rate among patients with hepatic encephalopathy and may be used as an add-on treatment.

The molecular mechanism of hepatocellular carcinoma (HCC) is partially demonstrated. Moreover, in the patients receiving multiple molecular-targeted therapies, the gene alternations are still unknown. Six molecular-targeted therapies of unresectable HCC (uHCC) and comprehensive genomic profiling (CGP) have been approved in clinical practice. Hence, the utility of CGP in patients with uHCC treated with multiple molecular-targeted agents is investigated. The data of the patients with uHCC who received CGP tests were collected, retrospectively, between February 2021 and May 2022. Gene alterations detected by foundation testing, excluding variants of unknown significance, were reported in all nine patients. The samples for CGP were derived from liver tumor biopsy (n = 2), surgical specimens of bone metastases (n = 2), and blood (n = 5). The median number of systemic therapies was four. Seven patients were candidates eligible for clinical trials. One patient with a high tumor mutation burden (TMB) could receive pembrolizumab after CGP. This study presented genomic alternations after receiving multiple molecular-targeted therapies. However, further investigation needs to be conducted to develop personalized therapies and invent newer agents for treating HCC.
RESUMEN
Objective Pemafibrate is a recently developed selective peroxisome proliferator-activated receptor alpha modulator that can improve alanine aminotransferase (ALT) levels in patients with nonalcoholic fatty liver disease (NAFLD). However, the effectiveness of ALT normalization with pemafibrate and bezafibrate, a traditional fibrate, has not been compared. Methods In this retrospective study, we compared the effects of pemafibrate and bezafibrate on ALT normalization in patients with NAFLD. The primary endpoint was the ALT normalization rate at 12 months after administration. Patients Twenty and 14 patients with NAFLD receiving pemafibrate and bezafibrate, respectively, were included in this retrospective analysis. All patients had elevated ALT levels and dyslipidemia at entry. Results The ALT normalization rates at 3, 6, and 12 months were 40%, 55%, and 60% for pemafibrate and 14.3%, 28.6%, and 14.3% for bezafibrate, respectively. The ALT normalization rate at 12 months was significantly higher in patients treated with pemafibrate than in those treated with bezafibrate (p=0.01). Pemafibrate, when compared with bezafibrate, was shown to be a significant factor for ALT normalization in a multivariable analysis with an adjusted odds ratio (95% confidence interval) of 13.8 (1.6-115, p=0.01). Conclusion Pemafibrate is effective in ALT normalization in patients with NAFLD and may be used as a treatment for NAFLD.
RESUMEN
Background: Advanced fibrosis detection in the general population is an unmet need. Additionally, screening method for advanced fibrosis in the general population is not established. Thus, this study aimed to examine the use of shear wave measurement (SWM), which measures liver stiffness by ultrasound elastography as a screening tool for advanced fibrosis in health checkups that represents the general population. Methods: SWM was performed in all subjects. Magnetic resonance elastography (MRE) was performed in those with SWM shear wave velocity (Vs) ≥1.3 m/s to determinate advanced fibrosis. The diagnostic accuracy of SWM Vs for advanced fibrosis (determined by MRE of ≥3.62 kPa) was examined. This prospective study was registered with the University Hospital Medical Information Network clinical trial registry (UMIN000041609). Results: A total of 2,233 subjects were included. SWM Vs of 1.64 m/s was selected as the best threshold for advanced fibrosis. Using the threshold of SWM Vs at ≥1.64 m/s, subjects were narrowed down to 1.7%, and sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for advanced fibrosis were 53.3%, 92.4%, 47.1%, and 94.0%, respectively, among these subjects. The multivariable analysis, after adjusting the age, sex, body mass index (BMI), hypertension, diabetes mellitus (DM), dyslipidemia, and alcohol use, revealed an SWM Vs of ≥1.64 m/s as the significant factor for advanced fibrosis with an odds ratio (95% confidence interval) of 14.5 (3.4-62; P<0.001). Conclusions: SWM has high diagnostic accuracy for advanced fibrosis (PPV 47.1%) and may be used as a screening tool for liver fibrosis in the general population.

RESUMEN
Background and Aim: Hepatocellular carcinoma development can be decreased by achieving and maintaining complete virological response (CVR) in chronic hepatitis B. However, it is unclear whether switching from entecavir (ETV) to tenofovir alafenamide (TAF) could achieve and maintain CVR in patients with low-level viremia (LLV; HBV DNA ≤ 3.3 log IU/mL) or occasional detectable HBV DNA during ETV treatment. Therefore, we aimed to examine whether the switching from ETV to TAF is effective in achieving CVR in patients with LLV or occasional detectable HBV DNA. Methods: This study comprised 45 patients who switched from ETV to TAF. All patients received ETV and TAF for >2 years, and the HBV DNA levels were measured every 3 months. Maintaining undetectable HBV DNA during 2-year period is defined as CVR. The primary endpoint is the CVR rate during ETV and TAF treatment. Results: The CVR rate for each of the 2 years of ETV and TAF therapy was 33.3% (15/45) and 68.9% (31/45, P < 0.01), respectively, and the CVR rate increased by switching from ETV to TAF. In patients with occasional detectable HBV DNA during ETV treatment (22 patients), 15 achieved CVR and 7 maintained occasional detectable HBV DNA. In patients with LLV during ETV treatment (eight patients), three achieved CVR and five had occasional detectable HBV DNA. Conclusion: Switching from ETV to TAF increases the CVR rate in patients with LLV or occasional detectable HBV DNA and could be an alternative treatment option.
RESUMEN
Objectives: Plastic stents (PS) used for preoperative biliary drainage (PBD) of pancreatic ductal adenocarcinomas (PDAC) tend to be associated with a high incidence of recurrent biliary obstruction (RBO). Although 10-mm diameter fully covered self-expanding metallic stents (FCSEMS) have come into use, vigilance is still required to prevent complications, such as cholecystitis and surgical site infection. The present study examined the efficacy and safety of the 6-mm diameter FCSEMS for PBD. Methods: The present retrospective study compared the incidence of complications associated with the use of 6-mm FCSEMS and PS. The inclusion criteria were a diagnosis of PDAC and preoperative endoscopic biliary tract drainage performed at our institution between April 2012 and June 2019. Results: Of the 51 patients enrolled, 25 and 26 patients received a PS and a 6-mm FCSEMS, respectively. The RBO incidence was significantly lower in the 6-mm FCSEMS group (7.7%) than in the PS group (40.0%) (p = 0.009), and time to RBO was significantly longer in the 6-mm FCSEMS group (HR = 6.008, p = 0.021). The patency rate at three months after stent placement was significantly higher in the latter group (83.5% vs. 45.3%, p = 0.009, Log-rank test). The groups did not differ significantly in terms of complications associated with PBD, such as cholecystitis and surgical site infection. Conclusion: The present findings suggested that the 6-mm FCSEMS may be an effective drainage device for use in PBD in PDAC treatment.
RESUMEN
BACKGROUND: Sarcopenia is associated with overall survival in patients with hepatocellular carcinoma (HCC). However, it is not known whether muscle volume is associated with clinical outcomes during combination therapy with immune checkpoint inhibitors. We investigated the relationship between changes in muscle volume and treatment outcomes in patients treated with atezolizumab plus bevacizumab. METHODS: Thirty-two patients with HCC who received atezolizumab plus bevacizumab as the first-line treatment between October 2020 and February 2022 were included. Skeletal muscle mass index (SMI) was calculated from the skeletal muscle area at the L3 level of the lumbar vertebrae. We compared pretreatment SMI and SMI at 6-14 weeks after administration. RESULTS: Of the 32 patients, 18 had a decreased SMI, while 14 did not. Progression-free survival (PFS) was significantly longer in patients without SMI decrease than in patients with SMI decrease (8.5 vs. 5.8 months, p = 0.011). There were no significant differences in treatment-related adverse events between the patients with and without SMI. Presarcopenia at baseline was not significantly associated with PFS. CONCLUSIONS: Decreased SMI was significantly associated with PFS. Monitoring muscle volume during atezolizumab plus bevacizumab therapy is useful in clinical practice.
RESUMEN
BACKGROUND: Prothrombin induced by vitamin K absence-II (PIVKA-II) was reported as a diagnosis and prognosis marker for hepatocellular carcinoma (HCC). Although the development of systemic therapies for advanced HCC has been remarkable, the role of PIVKA-II is unclear. This prospective study aimed to verify Elecsys PIVKA-II compared with Lumipulse PIVKA-II in a cohort with advanced HCC undergoing systemic therapy. METHODS: A total of 62 HCC patients who were treated with atezolizumab and bevacizumab (ATZ+BEV) and molecular targeted agents (MTAs) were prospectively enrolled at Musashino Red Cross Hospital from January 2020 to December 2020. A total of 208 serum samples from 52 patients were tested using Elecsys PIVKA-II and Lumipulse PIVKA-II assays. Furthermore, the relationship of Elecsys PIVKA-II and progression-free survival (PFS) was investigated with 48 patients (24 ATZ+BEV and 24 MTAs) whose Lumipulse PIVKA-II levels were >40 mAU/mL. RESULTS: In the test accuracy analysis, the Elecsys assay has a correlation coefficient (R) of 0.92 compared with that of the Lumipulse assay (ATZ+BEV, 0.95; MTAs, 0.91). In the PFS analysis, the number of patients who received ATZ+BEV and MTAs as first- and late-line therapy were 9 and 13, and 15 and 11, respectively. The PIVKA-II response was defined for patients who had a reduction in the Elecsys PIVKA-II level on the first month of treatment evaluation. The PFS of patients with Elecsys PIVKA-II response was significantly longer than that of nonresponse patients (5.8 months vs 3.8 months, p = 0.0205). CONCLUSION: The Elecsys PIVKA-II was not only as useful as the Lumipulse PIVKA-II but also for stratifying the PFS of patients with advanced HCC.

Background and Aim: Conversion surgery (CS), which aims to cure after systematic therapy, is only scarcely reported in the field of hepatocellular carcinoma (HCC). However, advancements in systemic therapy for HCC are expected to increase the candidates eligible for CS because of the higher response rate. The aim of this study was to clarify the characteristics of patients who underwent CS after tyrosine kinase inhibitor (TKI) therapy. Methods: In all, 364 patients who were treated with first-line sorafenib (SOR; n = 292) and lenvatinib (LEN; n = 72) from July 2009 to October 2020 were retrospectively enrolled. The endpoint of this analysis was overall survival (OS), and factors associated with CS are revealed. Results: Six patients underwent CS after TKI therapy, and of these four (1.4%) and two (2.7%) patients received SOR and LEN, respectively. At baseline, patients who underwent CS were significantly younger (median 52 [range, 46-83] years of age, P = 0.019), and their etiology included viral hepatitis, especially hepatitis B virus (HBV) (P = 0.049). Improvements or maintenance of preoperative modified albumin-bilirubin grade from baseline were observed in five (83.3%) patients, and partial radiologic response was observed in four (66.7%) patients. The median OS and 3-year survival rate of patients treated with CS were "not reached" and 80.0%, respectively. Conclusion: The patients who underwent CS after TKI therapy for HCC experienced long survival, were relatively young, and exhibited radiologic response to TKIs, and their liver function was either maintained or improved. Therefore, CS may lead to a better prognosis in patients with advanced HCC.
RESUMEN
Aims: Portopulmonary hypertension (PoPH) is a subtype of pulmonary arterial hypertension related to portal hypertension. The definitive diagnosis of PoPH is made by invasive right heart catheterization. Alternatively, pulmonary arterial hypertension may be recognized noninvasively from the tricuspid regurgitant pressure gradient (TRPG), measured by echocardiography. In this study, we aimed to establish a simple algorithm to identify chronic liver disease patients with a high TRPG value in order to narrow down the candidates to receive echocardiography. Methods and Results: TRPG was measured by echocardiography in 152 patients with chronic liver disease. Factors predictive of TRPG >30 mmHg were investigated. There were 28 (18%) cases with TRPG >30 mmHg. Independent factors associated with a high TRPG were the presence of shortness of breath, high serum brain natriuretic peptide (BNP), and low serum albumin. Child-Pugh class or the presence of ascites, varices, or encephalopathy was not associated with TRPG. There was a correlation between the serum BNP and TRPG, and the optimal cutoff value of BNP by the Youden index was 122 pg/mL, and by 100% sensitivity was 50 pg/mL. A combination of these factors identified patients with a high probability of TRPG >30 mmHg (n = 12, positive predictive value [PPV] of 83%), no probability (n = 80, PPV 0%), and intermediate probability (n = 60, PPV 25-34%). This algorithm has reduced the number of patients needing echocardiography by 53%. Conclusions: A simple algorithm using the presence of shortness of breath, serum BNP, and albumin levels can narrow down the candidates to receive echocardiography.
