To identify predictors of severe adverse events (≥grade 3) in patients with advanced hepatocellular carcinoma treated with lenvatinib.Of 41 patients, 25 and 16 were stratified into the severe and non-severe adverse events groups, respectively. Of these, 19 formed a lactulose-mannitol test subgroup, which was divided into severe adverse events (n=11) and non-severe adverse events (n=8) groups. Severe adverse events were assessed by liver disease etiology and modified albumin-bilirubin grade. Intestinal permeability by lactulose-mannitol test and serum soluble CD163, soluble mannose receptor, and zonulin levels.Severe adverse event incidence rates were higher in patients with advanced hepatocellular carcinoma related to alcoholic liver disease and nonalcoholic fatty-liver disease than in those with advanced hepatocellular carcinoma of other etiologies (p=0.014). The rates were higher for modified albumin-bilirubin grades 2a and 2b compared to modified albumin-bilirubin grade 1 (p=0.0104). Zonulin levels were higher in the severe adverse event group (p=0.0331) and were independently associated with severe adverse events (odds ratio=140, 95% confidence interval=1.66-11800; p=0.029). Patients with high zonulin levels (≥0.518 ng/ml) experienced more severe adverse events than those with low levels (0.518 ng/ml) (p=0.0137). In the lactulose-mannitol test subgroup, the urine lactulose:mannitol ratio was higher in the severe vs. non-severe adverse event group (p=0.0164). Moreover, it was higher in patients with alcoholic liver disease and nonalcoholic fatty-liver disease-related advanced hepatocellular carcinoma compared to those with other advanced hepatocellular carcinoma etiologies (p=0.0108).Serum zonulin levels predict severe adverse events in patients with advanced hepatocellular carcinoma treated with lenvatinib.

Although gut-derived lipopolysaccharide (LPS) affects the progression of non-alcoholic steatohepatitis (NASH) pathogenesis, few studies have focused on this relationship to develop treatments for NASH.To explore the effects of combination with rifaximin and lubiprostone on NASH liver fibrosis through the modulation of gut barrier function.To induce steatohepatitis, F344 rats were fed a choline-deficient l-amino acid-defined (CDAA) diet for 12 weeks and received oral administration of rifaximin and/or lubiprostone. Histological, molecular, and fecal microbial analyses were performed. Barrier function in Caco-2 cells were assessed by in vitro assays.Combination rifaximin/lubiprostone treatment significantly suppressed macrophage expansion, proinflammatory responses, and liver fibrosis in CDAA-fed rats by blocking hepatic translocation of LPS and activation of toll-like receptor 4 signaling. Rifaximin and lubiprostone improved intestinal permeability via restoring tight junction proteins (TJPs) with the intestinal activation of pregnane X receptor and chloride channel-2, respectively. Moreover, this combination increased the abundance of Bacteroides, Lactobacillus, and Faecalibacterium as well as decreased that of Veillonella resulting in an increase of fecal short-chain fatty acids and a decrease of intestinal sialidase activity. Both agents also directly suppressed the LPS-induced barrier dysfunction and depletion of TJPs in Caco-2 cells.The combination of rifaximin and lubiprostone may provide a novel strategy for treating NASH-related fibrosis.

Background/Aim: The management of refractory ascites is critical for the treatment of patients with decompensated cirrhosis. This study aimed to evaluate the feasibility and safety of cell-free and concentrated ascites reinfusion therapy (CART) in patients with cirrhosis and refractory ascites, with a focus on changes in coagulation and fibrinolytic factors in ascitic fluid following CART. Patients and Methods: This was a retrospective cohort study including 23 patients with refractory ascites undergoing CART. Serum endotoxin activity (EA) before and after CART and the levels of coagulation and fibrinolytic factors and proinflammatory cytokines in original and processed ascitic fluid were measured. The Ascites Symptom Inventory-7 (ASI-7) scale was used for subjective symptom assessment before and after CART. Results: Body weight and waist circumference significantly decreased after CART, whereas serum EA did not significantly change after CART. Similar to the previous reports, ascitic fluid concentrations of total protein, albumin, high-density lipoprotein cholesterol, γ-globulin, and immunoglobulin G levels were significantly increased after CART; mild elevations in body temperature and interleukin 6 and tumor necrosis factor-alpha levels in ascitic fluid were also observed. Importantly, the levels of antithrombin-III, factor VII, and X, which are useful for patients with decompensated cirrhosis, were markedly increased in the reinfused fluid during CART. Finally, the total ASI-7 score was significantly lower following CART, compared with the pre-CART score. Conclusion: CART is an effective and safe approach for the treatment of refractory ascites that allows the intravenous reinfusion of coagulation and fibrinolytic factors in the filtered and concentrated ascites.

Background/Aim: Sarcopenia increases the mortality in patients with cirrhosis. Approximately 60% of zinc is accumulated in skeletal muscle. We aimed to determine the role of subclinical zinc deficiency on sarcopenia development in patients with cirrhosis. Patients and Methods: We enrolled 151 patients with cirrhosis and divided them into the group with normal serum zinc levels (Group N: 80-130 μg/dl; n=38) and group with subclinical zinc deficiency (Group D

In previous works, we developed a self-healing organic coating with dispersed spherical capsules for corrosion protection. The capsule consisted of a polyurethane shell and healing agent as the inner. When the coating was damaged physically, the capsules were broken, and the healing agent was released from the broken capsules to the damaged area. The healing agent could react with moisture in the air to form the self-healing structure and cover the damaged area of coating. In the present investigation, a self-healing organic coating with spherical and fibrous capsules was formed on aluminum alloys. The corrosion behavior of the specimen coated with the self-healing coating was examined in a Cu2+/Cl− solution after physical damage, and it was found that no corrosion occurred during the corrosion test. This is discussed in terms of the high healing ability of fibrous capsules as a result of the high projected area.

Background: Ascites commonly complicates cirrhosis and is refractory to the vasopressin-2 antagonist tolvaptan and fluid restriction in approximately 60% of patients. We aimed to identify risk factors associated with adverse events following cell-free and concentrated ascites reinfusion therapy (CART) in patients with cirrhosis and ascites. Patients and Methods: We evaluated the efficacy and tolerability to the CART system in 18 patients with decompensated liver cirrhosis and ascites. We determined serum endotoxin activity using endotoxin activity (EA) assays and serum and ascitic fluid concentrations of interleukin 6 (IL6) and tumor necrosis factor-α (TNFα) before and after the CART procedures. Results: Body weight and waist circumference significantly decreased after CART (both p

Globally, the number of patients with primary biliary cholangitis (PBC) is increasing. Growing evidence suggests that oxidative stress plays a significant role in the pathogenesis of chronic liver disease regardless of its etiology. Hesperidin, a natural antioxidative substance derived from citrus peel, has been shown to have an anti-inflammatory effect in a rat arthritis model and may be a potential substance to attenuate intrahepatic inflammation in patients with PBC. In this study, the potential of glucosyl hesperidin as a therapeutic agent for PBC will be investigated through antioxidative stress mechanisms.Patients with PBC who are 20 years or older will be eligible to participate. Patients will be assigned to 1 of 2 groups and given either 500 or 1000 mg of glucosyl hesperidin per day. The primary endpoint is the ratio of changes in serum gamma-glutamyl transferase levels before and after 24 weeks of glucosyl hesperidin administration. The secondary endpoints are serum hepatobiliary enzyme levels (alkaline phosphatase, transaminase, and total bilirubin levels) and the protein expression levels of nuclear factor erythroid 2-related factor 2 and its target molecule 8, 16, and 24 weeks after administration compared to before administration.The prospective clinical interventional study was designed to assess the supportive effect of glucosyl hesperidin on hepatic function in patients with PBC receiving basic ursodeoxycholic acid treatment.

Serial pancreatic juice aspiration cytological examination (SPACE) via endoscopic retrograde cholangiopancreatography is a useful diagnostic method for early-stage pancreatic cancer, such as carcinoma in situ that are difficult to diagnose by endoscopic ultrasound-guided fine needle aspiration (EUS-FNA). However, the diagnostic accuracy of SPACE is low, which is attributed to problems regarding specimen treatment. Hence, we evaluated the diagnostic efficacy of liquid-based cytology (LBC) in pancreatic juice cytology for pancreatic cancer.We retrospectively analyzed 24 patients with suspected pancreatic cancer that was difficult to diagnose by endoscopic ultrasound-guided fine needle aspiration who underwent SPACE using LBC between April 2017 and April 2021.The most common reason for performing SPACE was localized stenosis of the main pancreatic duct without a mass. Eleven patients were diagnosed with malignancy after surgical resection, nine of whom had pancreatic ductal adenocarcinoma. Ten patients were diagnosed as benign after a follow-up of more than 1 year. The nine cases of malignancy were diagnosed before surgical resection by SPACE using LBC, with a sensitivity of 81.8% and specificity of 100%. The overall diagnostic accuracy was 91.7%. A total of 152 LBC examinations were performed via SPACE, with an adequate sample collection rate of 88.9%. No adverse events, including acute pancreatitis, occurred after endoscopic retrograde cholangiopancreatography.SPACE with LBC offers good diagnostic efficacy in patients with pancreatic cancer that is difficult to diagnose by endoscopic ultrasound-guided fine needle aspiration.

The current study evaluated the efficacy and toxicity of atezolizumab plus bevacizumab in patients with advanced-stage hepatocellular carcinoma in a real-world setting.This retrospective study enrolled 23 patients. The primary endpoint was progression-free survival (PFS). Antitumor responses 6 weeks after initiation of atezolizumab plus bevacizumab were assessed using the Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 and the modified RECIST (mRECIST). The Common Terminology Criteria for Adverse Events version 5.0 was used to evaluate the severity of adverse events. Relative changes in hepatic function and nutritional status were investigated.The median PFS was 119 days. The objective response rate (ORR) and disease control rate (DCR) at 6 weeks based on RECIST were 21.7% and 60.9%, respectively. The ORR and DCR based on mRECIST were 26.1% and 69.6%, respectively. The group with hepatitis B/C-related HCC had a higher ORR based on mRECIST than the non-hepatitis B and C-related group. Patients with Barcelona Clinic Liver Cancer (BCLC) stage A and B disease had a higher DCR based on RECIST than those with BCLC stage C disease. The incidence rates of any grade and grade ≥3 adverse events were 65.2% and 21.7%, respectively. The albumin-bilirubin and Child-Pugh scores, neutrophil-to-lymphocyte ratio and skeletal muscle index did not significantly worsen within 6 weeks after treatment initiation.Atezolizumab plus bevacizumab is effective and safe and can help achieve complete remission in patients with advanced-stage hepatocellular carcinoma in a real-world setting. Nevertheless, large-scale studies must be conducted to validate its outcomes in this patient group.

The gut‑liver‑muscle axis is associated with the development of sarcopenia in liver cirrhosis. The present study aimed to illustrate the combined effects of rifaximin and L‑carnitine on skeletal muscle atrophy in cirrhotic rats with steatohepatitis. For this purpose, a total of 344 Fischer rats were fed a choline‑deficient L‑amino acid‑defined (CDAA) diet with the daily oral administration of rifaximin (100 mg/kg) and/or L‑carnitine (200 mg/kg), and measurements of psoas muscle mass index and forelimb grip strength were performed. After feeding for 12 weeks, blood samples, and liver, ileum and gastrocnemius muscle tissues were harvested. The effects of L‑carnitine on rat myocytes were assessed using

The prognosis of highly advanced unresectable hepatocellular carcinoma (HCC) with a portal vein tumor thrombus (PVTT) is poor. There are currently no reports of long-term survival for up to 5 years in patients with advanced HCC who were treated with sorafenib. We describe a patient with Vp4 HCC who was treated with a sorafenib-based multidisciplinary treatment and experienced long-term survival, which may be the longest survival to date. A man in his late 60 s presented with general fatigue. Eight years previously, he received interferon monotherapy for chronic hepatitis C for 48 weeks and achieved a sustained virological response. He was diagnosed with a PVTT (Vp4) with diffuse-type HCC in the S6 lobe of the liver. He received hepatic arterial infusion of chemotherapy using 5-fluorouracil and cisplatin. Because of the occurrence of adverse effects, he was placed on sorafenib treatment. The treatment was effective and the HCC reduced. However, after 3 years of treatment, a 2-cm HCC was observed in the S5 lobe, and the patient underwent laparoscopic partial hepatectomy. After the operation, he continued to receive sorafenib, with no obvious recurrence, and survived for over 108 months after the first treatment. There are currently no reported cases of long-term progression-free survival by sorafenib for five years in patients of Vp4 HCC. In conclusion, we report a case of longest survival of a patient with Vp4 HCC treated with sorafenib-based multidisciplinary treatment.

BACKGROUND Prediction of HAIC treatment response is important for improving the prognosis in patients with hepatocellular carcinoma (HCC). The progression of HCC is related to hypercoagulability and angiogenesis. It is known that ADAMTS13 and von Willebrand factor (VWF) are related to hypercoagulability. In addition, previous study reported that the association between ADAMTS13 and VWF, and angiogenesis via vascular endothelial growth factor (VEGF). Recently, ADAMTS13 and VWF have been associated with the prognosis in patients with various kinds of cancer undergoing chemotherapy. AIM To investigate whether ADAMTS13 and VWF become useful biomarkers of treatment response in HCC patients before the initiation of HAIC treatment. METHODS Seventy-two patients were enrolled in this study. ADAMTS13 activity (ADAMTS13:AC), VWF antigen (VWF:Ag) and VEGF levels were determined via enzyme-linked immunosorbent assay. Univariable and multivariable analyses were performed to determine the predictive factors of treatment response in patients with HCC undergoing HAIC treatment. RESULTS ADAMTS13:AC levels in HCC patients with stable disease (SD) + partial response (PR) of HAIC treatment were significantly higher than those with progressive disease (PD) (P < 0.05). In contrast, VWF:Ag/ADAMTS13:AC ratio and VEGF levels in HCC patients with SD + PR were significantly lower than those with PD (both P < 0.05). Patients with high VWF:Ag/ADAMTS13:AC ratio (> 2.7) had higher VEGF levels than those with low ratio (≤ 2.7). Multivariable analysis revealed that VWF:Ag/ADAMTS13:AC ratio was a predictive factor of HAIC treatment response. CONCLUSION VWF:Ag/ADAMTS13:AC ratio may become a useful biomarker of treatment response in HCC patients before the initiation of HAIC treatment.

Chronic hepatitis B (CHB) virus continues to be a leading cause of morbidity and mortality worldwide. The diagnosis of liver fibrosis has a key role in selecting patients with CHB for antiviral treatment. However, serum biomarkers demonstrate limited diagnostic utility. The present study aimed to compare the performances of fibrosis biomarkers for diagnosing significant liver fibrosis that indicates the need for antiviral therapy in patients with CHB and to identify the most appropriate biomarker for these patients. The current study included 96 antiviral-naive patients with CHB who underwent liver biopsy. METAVIR scoring system was used to assess liver fibrosis and necroinflammation. The diagnostic performances were evaluated of the platelet (PLT) count; the levels of hyaluronan, serum 7S domain of type 4 collagen, procollagen type III N-terminal peptide, tissue inhibitor of metalloproteinases 1, Mac-2 binding protein glycosylation isomer (M2BPGi) and N-terminal type III collagen propeptide (Pro-C3); the fibrosis index based on four factors; the aspartate aminotransferase-to-platelet ratio index; and enhanced liver fibrosis score for identifying significant liver fibrosis [≥fibrosis stage 2 (F2)]. All fibrosis biomarkers, except the Pro-C3 level, correlated with the fibrosis stage. M2BPGi was better than other biomarkers for diagnosing ≥F2, with the highest area under the curve of 0.902. M2BPGi demonstrated a higher diagnostic accuracy for significant fibrosis than mild/severe fibrosis or cirrhosis. However, no significant correlation was observed between the M2BPGi level and fibrosis stage in patients with CHB having significant liver necroinflammation defined as ≥ necroinflammatory activity 2. The M2BPGi level and PLT count were exclusively correlated with the fibrosis stage in 73 patients without significant liver necroinflammation. M2BPGi demonstrated the highest diagnostic performance for significant fibrosis in patients having significant liver fibrosis with no significant liver necroinflammation. In conclusion, the M2BPGi level can accurately diagnose significant liver fibrosis that indicates the need for antiviral therapy in patients with CHB.

ADAMTS13 specifically cleaves the multimeric von Willebrand factor (VWF), and an imbalance between ADAMTS13 activity (ADAMTS13:AC) and VWF antigen (VWF:Ag) levels is associated with the severity of liver cirrhosis (LC). However, the reason for this imbalance in patients with LC is unknown. This study investigated the relationship among ADAMTS13:AC, VWF:Ag, and endotoxin (Et) levels in patients with LC. ADAMTS13:AC and VWF:Ag levels were determined using ELISA, whereas Et levels were estimated using a chromogenic substrate assay. The levels of ADAMTS13 inhibitor (ADAMTS13:INH) were evaluated by measuring the extent that heat-inactivated patient’s plasma reduces the ADAMTS13:AC of the control. The status (degraded, normal, or unusually large [UL]) of the VWF multimer (VWFM) was determined through vertical agarose gel electrophoresis. ADAMTS13:AC, VWF:Ag, and Et levels decreased, increased, and increased, respectively, with the severity of LC. Patients with cirrhosis with high Et levels had lower and higher ADAMTS13:AC and VWF:Ag levels, respectively, than those with low Et levels. Patients with cirrhosis with detectable ADAMTS13:INH had higher Et levels than those with undetectable ADAMTS13:INH. Patients whose VWFM was either normal or UL had higher Et levels than those with degraded VWFM. In conclusion, ADAMTS13, VWF, and Et may be interrelated and associated with the severity of LC via hypercoagulability.

Mortality and recurrence rates of hepatocellular carcinoma (HCC) are high. Recent studies show that for patients with HCC beyond up-to-seven criteria, treatment with molecular-targeted agents (MTAs) is recommended because the treatment efficiency of transcatheter arterial chemoembolization (TACE) is poor, further, TACE increases decline in liver function. However, the relationship between TACE and liver function decline in patients with HCC within up-to-seven criteria has not been clarified. Hence, we aimed to investigate this relationship. This retrospective observational study included 189 HCC tumors within up-to-seven criteria in 114 Child–Pugh class A patients. Twenty-four (12.7%) tumors were changed from Child–Pugh class A to B after TACE, and 116 (61.4%) tumors exhibited recurrence within 6 months after TACE. Prothrombin time (PT) and albumin–bilirubin (ALBI) score before TACE were significantly associated with liver dysfunction from Child–Pugh class A to B. The combination of PT and ALBI score before TACE had high predictive ability for liver dysfunction from Child–Pugh class A to B after TACE (specificity = 100%, sensitivity = 91.7%). The combined use of pre-TACE PT and ALBI score has a high predictive ability for liver dysfunction after TACE for Child–Pugh class A patients with HCC within up-to-seven criteria.

We aimed to prospectively identify the risk factors of sarcopenia in patients with cirrhosis. Patients (n = 193) included in a discovery cohort (January 2011 and December 2014) were categorized into alcoholic (A1; n = 55) and non-alcoholic cirrhosis (NA; n = 138) groups, and those (n = 235) in a validation cohort (January 2015 to December 2019) were categorized into alcoholic (n = 92), non-alcoholic steatohepatitis-related (n = 27), and hepatitis C virus-related cirrhosis groups (n = 116). Skeletal muscle mass index (SMI) was determined using computed tomography (SMI-CT) and bioelectrical impedance analysis (SMI-BIA). Endotoxin activity (EA) was measured with an EA assay. SMI-CT correlated with grip strength in all the groups but significantly correlated with SMI-BIA of the men in group A1 (R = 0.64, P

Aims: Thrombocytopenia is a common complication among patients with chronic liver disease (CLD). To increase platelet counts, lusutrombopag, a small-molecule, second-generation thrombopoietin receptor agonist, was developed in September 2015. Lusutrombopag is mainly used in patients with platelet counts Methods: We evaluated 36 patients who received lusutrombopag for CLD. Changes in platelet counts were evaluated. A treatment response was defined as an increasing platelet count ≥20,000/µL from baseline after drug administration. The differences related to these changes between platelet counts ≥50,000 and Results: Of the patients, 25 had platelet counts ≥50,000/µL. The increase in platelet count and the date in which it reached a maximum did not significantly differ between the groups. The effectiveness of lusutrombopag did not significantly differ between the groups. In both groups, no adverse reaction was observed during lusutrombopag administration. Conclusion: In this study, we showed the effectiveness of lusutrombopag, which had no complications. This study is the first to report that the effectiveness of lusutrombopag was the same for patients with platelet counts ≥50,000/µL and

BACKGROUND Early diagnosis of hepatocellular carcinoma (HCC) is necessary to improve the prognosis of patients. However, the currently available tumor biomarkers are insufficient for the early detection of HCC. Acylcarnitine is essential in fatty acid metabolic pathways. A recent study reported that a high level of acylcarnitine may serve as a useful biomarker for the early diagnosis of HCC in steatohepatitis (SH) patients. In contrast, another study reported that the level of acetylcarnitine (AC2) - one of the acylcarnitine species - in non-SH patients with HCC was decreased vs that reported in those without HCC. AIM To investigate the usefulness of acylcarnitine as a biomarker for the early diagnosis of HCC in non-SH patients. METHODS Thirty-three non-SH patients (14 with HCC and 19 without HCC) were enrolled in this study. Blood samples were obtained from patients at the time of admission. The levels of acylcarnitine and AC2 in the serum were determined through tandem mass spectrometry. The levels of vascular endothelial growth factor (VEGF) and VEGF receptor 2 (VEGFR-2) were determined by enzyme-linked immunosorbent assay. Univariate and multivariate analyses were used to determine early diagnostic factors of HCC. RESULTS The level of acylcarnitine was significantly lower in non-SH patients with HCC vs those without HCC (P < 0.05). In contrast, the level of lens culinaris agglutinin-reactive fraction of α-fetoprotein (AFP) - AFP-L3% - was significantly higher in non-SH patients with HCC vs those without HCC (P < 0.05). However, the levels of total carnitine, free carnitine, AFP, des-γ-carboxy prothrombin, VEGF, and VEGFR-2 were not different between patients with and without HCC. The multivariate analysis showed that a low level of acylcarnitine was the only independent factor for the early diagnosis of HCC. The patients with a low level of AC2 had a significantly higher level of VEGF vs those with a high level of AC2 (P < 0.05). CONCLUSION The metabolic pathways of fatty acids may differ between SH HCC and non-SH HCC. Further studies are warranted to investigate these differences.

Aim Non-alcoholic steatohepatitis (NASH) has a broad clinicopathological spectrum (inflammation to severe fibrosis). The farnesoid X receptor agonist obeticholic acid (OCA) ameliorates the histological features of NASH; satisfactory antifibrotic effects have not yet been reported. Here, we investigated the combined effects of OCA + a dipeptidyl peptidase-4 inhibitor (sitagliptin) on hepatic fibrogenesis in a rat model of NASH. Methods Fifty Fischer 344 rats were fed a choline-deficient L-amino-acid-defined (CDAA) diet for 12 weeks. The in vitro and in vivo effects of OCA + sitagliptin were assessed along with hepatic fibrogenesis, lipopolysaccharide-Toll-like receptor 4 (TLR4) regulatory cascade and intestinal barrier function. Direct inhibitory effects of OCA + sitagliptin on activated hepatic stellate cells (Ac-HSCs) were assessed in vitro. Results Treatment with OCA + sitagliptin potentially inhibited hepatic fibrogenesis along with Ac-HSC proliferation and hepatic transforming growth factor (TGF)-β1, α1(I)-procollagen, and tissue inhibitor of metalloproteinase-1 (TIMP-1) mRNA expression and hydroxyproline levels. Obeticholic acid inhibited hepatic TLR4 expression and increased hepatic matrix metalloproteinase-2 expression. Obeticholic acid decreased intestinal permeability by ameliorating CDAA diet-induced zonula occludens-1 disruption, whereas sitagliptin directly inhibited Ac-HSC proliferation. The in vitro suppressive effects of OCA + sitagliptin on TGF-β1 and α1(I)-procollagen mRNA expression and p38 phosphorylation in Ac-HSCs were almost consistent. Sitagliptin directly inhibited the regulation of Ac-HSC. Conclusions Treatment with OCA + sitagliptin synergistically affected hepatic fibrogenesis by counteracting endotoxemia induced by intestinal barrier dysfunction and suppressing Ac-HSC proliferation. Thus, OCA + sitagliptin could be a promising therapeutic strategy for NASH.

AIM To identify laboratory predictors of histological progression (HP) of primary biliary cholangitis (PBC). METHODS Sequential biopsies were carried out on 35 (11.4%) of 308 patients with PBC treated with ursodeoxycholic acid (UDCA). Patients were divided into high γ-glutamyl transpeptidase (GGT) (n = 18) and low GGT (n = 17) groups, based on the median value of GGT at baseline. Patients were then categorized as showing HP (progressive group, PG) or lacking HP (non-progressive group, NPG) according to the Scheuer and Nakanuma classifications, with the latter grading liver fibrosis (fibrosis score) and bile duct loss (BDL score). RESULTS According to the Scheuer definition, 12 patients had HP and 23 did not. According to the Nakanuma definition, 8 and 27 patients were in the PG and NPG groups, respectively. The fibrosis and BDL scores progressed in 13 and 8 patients, respectively, whereas 22 and 25 patients did not show HP, respectively. Fisher's exact probability test analysis revealed that the rate of HP using the Nakanuma fibrosis score was significantly higher in the high GGT group compared to the low GGT group (P

Background: This study aimed to compare the diagnostic performance of carbohydrate-deficient transferrin (CDT) and gamma-glutamyltranspeptidase (γ-GTP) to assess the single and combined benefits of these biological markers for the detection of chronic excessive alcohol consumption in patients with alcoholic cirrhosis. Methods: Biological markers were determined in blood samples from patients with alcoholic cirrhosis (drinking group, n = 35, nondrinking group, n = 81). The prediction accuracy of %CDT alone, γ-GTP alone, and their combination for the detection of excessive alcohol consumption was determined in patients with alcoholic cirrhosis. Results: Serum total bilirubin, alanine aminotransferase, aspartate aminotransferase, γ-GTP, and alkaline phosphatase levels and %CDT were significantly higher and serum albumin levels were significantly lower in the drinking group than in the nondrinking group. The combination of %CDT and γ-GTP compared with %CDT or γ-GTP alone showed a higher prediction accuracy. The combination of %CDT and γ-GTP exhibited a higher specificity than γ-GTP alone. However, in terms of sensitivity, no significant difference was found between single or combined markers. Conclusions: The combination of %CDT and γ-GTP is considered a useful biomarker of chronic excessive alcohol consumption in patients with alcoholic cirrhosis.

Background Methotrexate-associated lymphoproliferative disorder (MTX-LPD) is a rare but critical complication that develops in patients treated with MTX. Although MTX-LPD has been recently reported, the incidence of follicular lymphoma in the intestine is very low. Case presentation A 73-year-old woman who had been receiving MTX for over 10 years visited our hospital complaining of postprandial abdominal pain and nausea. Upper and lower digestive tract endoscopies did not show any abnormal findings. A patency capsule was stagnated at the proximal part of the ileum with a mild dilation on the oral side. An oral balloon endoscopy revealed shallow ulcerative lesions in the jejunum. She was diagnosed with MTX-LPD based on histopathological findings. The symptoms did not improve with the discontinuation of MTX, and the patient required partial resection of the small intestine. The test result for Epstein-Barr virus-encoded small RNA was negative. She was diagnosed with follicular lymphoma based on the histology findings of a surgical specimen. Postoperative positron emission tomography-computed tomography and bone marrow aspiration did not show any findings of lymphoma. On follow-up, no recurrence was noted four years after the surgery. Conclusions Herein, we report the first case of follicular lymphoma that occurred in the small intestine, negative for Epstein-Barr virus-encoded small RNA. If intestinal symptoms occur during MTX administration, it is important to directly observe by endoscopy and perform histological examination.

Equol is a metabolite of daidzein, a major soybean isoflavone with estrogenic and antioxidant activities. As the production of equol depends on the presence of certain members of the intestinal microflora, not all individuals can produce equol. The incidence of nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) increases in menopausal women, and estrogen is associated with the progression of NAFLD/NASH. Therefore, the status of equol production might also be related to the pathogenesis of NAFLD/NASH in women. We, thus, examined the relationship between NASH histological features and equol production. Thirty-eight NAFLD patients who underwent liver biopsy were included in this study. In women, the degree of fibrosis and ballooning in nonproducers was significantly higher than that in producers. The percentage of nonproducers with NAFLD activity score (NAS) ≥5 was significantly higher than that of producers. None of the histological features were significantly different between nonproducers and producers in men. Decision tree analysis identified the predictors of NAS ≥5 in women. The status of equol production was the strongest predictor, followed by fasting glucose. Equol can be noninvasively detected in urine, suggesting its application as a screening test for predicting the diagnosis and progression of NASH in women.

A potential restriction of the Baveno VI consensus, which helps to avoid unnecessary endoscopies, is the limited availability of FibroScan. We aimed to identify serum fibrosis indices that might aid in ruling out the presence of high-risk varices in cirrhotic patients. This retrospective study included 541 consecutive patients with cirrhosis who underwent endoscopy and had data available for nine serum fibrosis indices, including platelet count, hyaluronic acid, 7S fragment of type 4 collagen, procollagen type III N-terminal peptide, tissue inhibitor of metalloproteinases 1, Mac-2 binding protein glycosylation isomer, fibrosis index based on four factors (FIB-4), aspartate transaminase/platelet ratio index and enhanced liver fibrosis score. Optimal index cutoffs for predicting high-risk varices were calculated in an estimation cohort (n = 127) and evaluated in a validation cohort (n = 351). The diagnostic performance of the indices was assessed by receiver operating characteristic curve analysis. In the estimation cohort, a FIB-4 cutoff of 2.78 provided the greatest diagnostic accuracy in predicting both all-grade and high-risk varices. FIB-4 had a negative predictive value of 1.00 for high-risk varices in both cohorts, and 21.3% (27/127) and 14.8% (52/351) of the estimation and validation cohorts, respectively, avoided esophagogastroduodenoscopy, no high-risk varices were missed in either cohort. FIB-4 correctly identifies the absence of high-risk varices in patients with cirrhosis. Therefore, those with a FIB-4 of &ge, 2.78 should undergo esophagogastroduodenoscopy, and FIB-4 determination should be recommended every 6&ndash, 12 months concurrently with the other blood tests until the index value reaches 2.78 in those with a FIB-4 of &lt, 2.78.

The progression of nonalcoholic steatohepatitis (NASH) is complicated. The multiple parallel-hits theory is advocated, which includes adipocytokines, insulin resistance, endotoxins, and oxidative stress. Pathways involving the gut&ndash, liver axis also mediate the progression of NASH. Angiotensin-II receptor blockers (ARB) suppress hepatic fibrosis via the activation of hepatic stellate cells (HSCs). Rifaximin, a nonabsorbable antibacterial agent, is used for the treatment of hepatic encephalopathy and has been recently reported to improve intestinal permeability. We examined the inhibitory effects on and mechanism of hepatic fibrogenesis by combining ARB and rifaximin administration. Fischer 344 rats were fed a choline-deficient/l-amino acid-defined (CDAA) diet for 8 weeks to generate the NASH model. The therapeutic effect of combining an ARB and rifaximin was evaluated along with hepatic fibrogenesis, the lipopolysaccharide&ndash, Toll-like receptor 4 (TLR4) regulatory cascade, and intestinal barrier function. ARBs had a potent inhibitory effect on hepatic fibrogenesis by suppressing HSC activation and hepatic expression of transforming growth factor-&beta, and TLR4. Rifaximin reduced intestinal permeability by rescuing zonula occludens-1 (ZO-1) disruption induced by the CDAA diet and reduced portal endotoxin. Rifaximin directly affect to ZO-1 expression on intestinal epithelial cells. The combination of an ARB and rifaximin showed a stronger inhibitory effect compared to that conferred by a single agent. ARBs improve hepatic fibrosis by inhibiting HSCs, whereas rifaximin improves hepatic fibrosis by improving intestinal permeability through improving intestinal tight junction proteins (ZO-1). Therefore, the combination of ARBs and rifaximin may be a promising therapy for NASH fibrosis.

Acute-on-chronic liver failure (ACLF) leads to systematic inflammatory response syndrome and multiple organ failure. This study investigated the relationship between endotoxin (Et) and ACLF with the aim of determining whether Et activity (EA) is useful as a predictive biomarker of ACLF development and whether rifaximin treatment decreased the risk of ACLF development. Two hundred forty-nine patients with liver cirrhosis were enrolled in this study. Et concentration was determined in the whole blood by a semiquantitative EA assay. Predictive factors of ACLF development and the risk of ACLF development with and without rifaximin treatment were identified by univariate and multivariate analysis using Fine and Gray&rsquo, s proportional subhazards model. EA level was higher in Child&ndash, Pugh class B than in class A patients, and class B patients had an increased risk of ACLF development compared with class A patients. Multivariate analysis showed that EA level was a predictive factor independently associated with ACLF development. Rifaximin decreased EA level and the risk of ACLF development in Child&ndash, Pugh class B patients. Et levels were associated with functional liver capacity and were predictive of ACLF development in cirrhotic patients. Rifaximin decreased Et level and the risk of ACLF development in advanced cirrhotic patients.
