Metabolic dysfunction-associated steatotic liver disease criteria may underestimate the number of lean female nonalcoholic fatty liver disease patients with significant liver fibrosis. Hepatol Res 2024; 54:429-438. [PMID: 38015179 DOI: 10.1111/hepr.13994] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Revised: 11/17/2023] [Accepted: 11/20/2023] [Indexed: 11/29/2023]
Abstract
AIM It remains unclear whether the newly defined concept of metabolic dysfunction-associated steatotic liver disease (MASLD) appropriately includes patients with nonalcoholic fatty liver disease with significant liver fibrosis. METHODS A total of 4112 patients in whom nonalcoholic fatty liver disease was diagnosed by ultrasonography during medical checkups were enrolled. We defined a fibrosis-4 index ≥1.3 in patients aged <65 years and ≥2.0 in patients aged ≥65 years as significant liver fibrosis. RESULTS The numbers of patients with a low, intermediate, and high probability of advanced fibrosis based on the fibrosis-4 index were 3360 (81.7%), 668 (16.2%), and 84 (2.0%). There were 3828 (93.1%) and 284 (6.9%) patients diagnosed with MASLD and non-MASLD. The non-MASLD group, compared with the MASLD group, was significantly younger (44 vs. 55 years) and had a higher percentage of women (62.3% vs. 27.7%). Significant fibrosis, defined based on the fibrosis-4 index, was present in 18.5% of the MASLD group and 15.5% of the non-MASLD group. In a multivariable analysis, female sex (OR 6.170, 95% CI 3.180-12.000; p < 0.001) was independently associated with non-MASLD in patients with a significant fibrosis. Among non-MASLD patients with a significant fibrosis (n = 44), body mass index was significantly lower in females than in males (p < 0.001). In a multivariable analysis of patients aged <65 years, female sex (OR, 7.700; 95% CI, 3.750-15.800; p < 0.001) remained independently associated with non-MASLD in patients with a significant fibrosis. CONCLUSIONS MASLD may inappropriately exclude patients with significant fibrosis, especially lean females with nonalcoholic fatty liver disease.

VFMAP predicted hepatocellular carcinoma development in patients with chronic hepatitis C who were treated with direct-acting antiviral and achieved sustained virologic response. J Med Ultrason (2001) 2024; 51:293-300. [PMID: 38147196 DOI: 10.1007/s10396-023-01398-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Accepted: 10/16/2023] [Indexed: 12/27/2023]
Abstract
PURPOSE Risk factors for the development of hepatocellular carcinoma (HCC) remain unclear in patients with hepatitis C virus (HCV) who achieve sustained virological response (SVR) after direct-acting antiviral (DAA) therapy. This study investigated the usefulness of the VFMAP scoring system for predicting the development of HCC in these patients. METHODS This study included 358 patients with HCV who achieved SVR after DAA treatment. The VFMAP system defines and scores cutoff values for virtual touch quantification (VTQ), fasting plasma glucose, sex, age, and alpha-fetoprotein values. All patients were grouped according to their VFMAP scores as follows: 0 or 1 point, low-score group; 2 or 3 points, intermediate-score group; and 4 or 5 points, high-score group. RESULTS Nineteen patients developed HCC. The median follow-up duration was 3.2 (1.5-4.0) years. The respective cumulative incidence rates of HCC at 12, 24, and 36 months were as follows in different subgroups: all study patients, 3.0%, 4.8%, and 6.6%; low-score group, 0.96%, 0.96%, and 0.96%; intermediate-score group, 2.6%, 4.5%, and 6.8%; and high-score group, 10.0%, 15.3%, and 18.5%. The cumulative incidence rates of HCC in the high-score group were significantly higher than those in the low- and intermediate-score groups (p < 0.001 and < 0.05, respectively). CONCLUSION VFMAP accurately predicted the development of HCC in HCV patients who achieved SVR following treatment with DAAs.

A Low Geriatric Nutritional Risk Index Is Associated with Low Muscle Volume and a Poor Prognosis among Cirrhotic Patients. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:2099. [PMID: 38138202 PMCID: PMC10744724 DOI: 10.3390/medicina59122099] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/05/2023] [Revised: 11/20/2023] [Accepted: 11/26/2023] [Indexed: 12/24/2023]
Abstract
Background and Objectives: The geriatric nutritional risk index (GNRI) is an easily calculable index that can be determined using three common clinical variables. The GNRI is suggested to be related to sarcopenia in cirrhotic patients. However, the relationship between the GNRI and the prognosis in patients with liver cirrhosis (LC) has not been reported. The aim of the present research is to study the association of the GNRI with the nutritional status, hepatic function reserve, and prognosis in patients with liver cirrhosis (LC). Materials and Methods: A total of 370 cirrhotic patients whose nutritional statuses were evaluated using anthropometric measurements and bioimpedance analysis were studied. The associations between the GNRI and nutritional status and the GNRI and hepatic function reserve were analyzed. We also investigated the GNRI and prognosis of patients with LC. Results: The median age of the enrolled patients was 66 years old, and 266 (71.9%) patients had viral hepatitis-related LC. The GNRI was shown to decrease with the progression of chronic liver disease, represented by an increased FIB-4 index and severe Child-Pugh and mALBI grades. In addition, a low GNRI (<92) was associated with severe cirrhosis-related metabolic disorders, including a low branched-chain amino acid-to-tyrosine ratio (BTR) and a low zinc value. The GNRI was positively correlated with two nutrition-related anthropometric variables (% arm circumference and % arm muscle circumference), and a low GNRI was related to a low skeletal muscle mass index (SMI) (<7.0 kg/m2 for men or <5.7 kg/m2 for women), as determined by using bioimpedance analysis. In addition, patients with a low GNRI (<92) had a poorer prognosis than those with a high GNRI (≥92) (log-rank test: p = 0.0161, and generalized Wilcoxon test, p = 0.01261). Conclusions: Our results suggest that a low GNRI is related to severe chronic liver disease, low muscle volume, and a poor prognosis of patients with cirrhosis.

Association of PNPLA3 SNP With the Development of HBV-related Hepatocellular Carcinoma. In Vivo 2023; 37:763-770. [PMID: 36881106 PMCID: PMC10026664 DOI: 10.21873/invivo.13139] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Revised: 01/10/2023] [Accepted: 01/11/2023] [Indexed: 03/08/2023]
Abstract
BACKGROUND/AIM Concomitant nonalcoholic fatty liver disease (NAFLD)/hepatic steatosis (HS) is suggested to increase the risk of hepatocellular carcinoma (HCC) in hepatitis virus B (HBV)-infected patients. Patatin-like phospholipase domain-containing 3 (PNPLA3) rs738409 gene single-nucleotide polymorphism (SNP) is well-known to be associated with the development of NAFLD/HS; however, it is still unclear whether this SNP is related to the development of HCC in HBV-infected patients. PATIENTS AND METHODS We investigated a total of 202 HBV-infected patients who received percutaneous liver biopsy, and simultaneously assessed biopsy-proven HS, insulin resistance, and the PNPLA3 SNP status. We further investigated the relationships of these factors with the development of HCC in HBV-infected patients. RESULTS Most of the enrolled cases (196/202: 97.0%) were non-cirrhotic patients. One hundred seventy-three patients (85.6%) received antiviral therapy. A Kaplan-Meier analysis showed that the incidence of HCC development in patients with HS was higher than that in patients without HS (p<0.01). An increased homeostasis model assessment as an index of insulin resistance (HOMA-IR) value (≥1.6) was associated not only with the presence of HS (p<0.0001) but also with the development of HCC (p<0.01). The PNPLA3 rs738409 SNP was also associated with the presence of HS (p<0.01) and the development of HCC (p<0.05) in HBV-infected patients. CONCLUSION In addition to HS and IR, PNPLA3 rs738409 SNP was suggested to be associated with the development of HCC in Japanese patients with HBV infection.

Diagnosis of hepatic steatosis based on ultrasound attenuation imaging is not influenced by liver fibrosis. Hepatol Res 2022; 52:1009-1019. [PMID: 36018852 DOI: 10.1111/hepr.13831] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Revised: 08/11/2022] [Accepted: 08/18/2022] [Indexed: 12/13/2022]
Abstract
AIM Recently, a new technique using attenuation imaging (ATI) was developed to diagnose hepatic steatosis. The aim of this study was to investigate whether ATI for the evaluation of hepatic steatosis is influenced by liver fibrosis. METHODS A total of 328 patients with chronic liver disease were enrolled to study the associations between histological hepatic steatosis or liver fibrosis and ATI findings. The interaction between liver fibrosis and ATI was also analyzed. RESULTS Median ATI values according to steatosis grade and fibrosis stage increased in line with the progression of liver steatosis (p < 0.001) and fibrosis (p < 0.05). However, in each steatosis grade, ATI values according to fibrosis stage were not significantly increased. In multiple regression analyses for assessment of the effect of their interaction, the p values for fibrosis stage, steatosis grade, and fibrosis stage × steatosis grade were 0.096, <0.001, and 0.077, respectively. Variance inflation factor values for fibrosis stage, steatosis grade, and fibrosis stage × steatosis grade were 1.079, 1.094, and 1.074, respectively. CONCLUSION Attenuation imaging values are not influenced by liver fibrosis.

Abstract
Abstract
Background
Catheter ablation (RFA) is significantly more effective in terms of arrhythmia recurrence rate than antiarrhythmic medication. For the duration of the procedure, the patient needs to remain motionless on the operation table. General anesthesia (GA) is widely used during atrial fibrillation (AF) ablation in all over the world, however RFA of AF is performed under conscious sedation (CS) in the most centers in Japan.
It remains controversial whether cardiac anesthesiologists are best suited to manage anesthesia in the electrophysiology lab.
Objective
The aim of this study was to report the efficacy and safety of GA during AF ablation.
Methods
297 patients (67.3±11.7 years, 208 men, 128 paroxysmal, mean follow up 443 days±306) with AF undergoing RFA in our department from January 2018 to December 2021 were retrospectively analyzed. 113 assigned to the GA group, 184 patients to the CS group.
The primary efficacy end point was radiofrequency time, ablation index, force time integral. The secondary end points defined AF recurrence and the complications.
Result
There was no difference in the baseline characteristics between the two groups. There was no difference between groups in AF recurrence (22.1% vs. 14.1%, P=0.103) and complications.However, Patients in GA had shorter radiofrequency times (66.9±3.7 minute vs 79.0±2.9 minutes P=0.01)Ablation index (376±18.6 vs 371±22.6 P<0.05), Force time integral (136±22.3 vs 111.4±45.3).
Conclusion
General anesthesia is superior to conscious sedation with shorter radiofrequency times and higher than Force time integral, ablation index. Moreover, it is not inferior in regard to arrhythmia recurrence or complication rates of catheter ablation of atrial fibrillation.

Modification of the ALBI-PLT Score for the Prediction of High-risk Varices. In Vivo 2022; 36:1360-1366. [PMID: 35478164 DOI: 10.21873/invivo.12839] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Revised: 03/02/2022] [Accepted: 03/03/2022] [Indexed: 11/10/2022]
Abstract
BACKGROUND/AIM A new scoring system [albumin-bilirubin-platelet (ALBI-PLT) score] was reported for identifying cirrhotic patients without high-risk varices (HRV), and patients with ALBI grade 1 (≤-2.60) and a platelet count over 150×109/l were shown to have a low risk of having HRV. The present study modified the cut-off values of the variables in the ALBI-PLT score. PATIENTS AND METHODS Among a total of 338 patients with chronic liver diseases, possible cut-off values of the ALBI score and the platelet count were determined by analyzing the first-half group (training cohort: N=169) with the receiver operating characteristic (ROC) method. The utility of the determined values was evaluated in the second-half group (validation cohort: N=169) and total cohort (N=338). In addition, the utility of the modified cut-off values was evaluated in patients with compensated cirrhosis (cirrhotic cohort: N=87). RESULTS Possible cut-off values of the ALBI score and platelet count were found to be -2.36 and 114×109/l, respectively. In the training cohort, these cut-off values provided a higher ratio of avoiding esophagogastroduodenoscopy than the original ALBI-PLT score (53.3% vs. 25.4%, p<0.01). Consistent results were observed in the validation cohort (28.4% vs. 15.4%, p<0.01), total cohort (40.8% vs. 20.4%, p<0.01), and cirrhotic cohort (32.2% vs. 11.5%, p<0.01). However, the missing ratio of patients with the HRV was not significantly increased in any cohort studied. CONCLUSION Modification of the ALBI-PLT score may be useful for predicting patients without HRV.

Abstract
BACKGROUND/AIM Recent advances in antiviral treatment have achieved a sustained viral response (SVR) in over 95% of hepatitis C virus (HCV) infections. HCV elimination is suggested to improve several lifestyle-related factors; however, few studies have focused on dietary habit-/appetite-related factors. PATIENTS AND METHODS HCV-infected patients who received Daclatasvir/Asnaprevir (DCV/ASV) therapy were enrolled, and the changes in appetite-related molecules after antiviral therapy were assessed with a multiple cytokine-measuring system. RESULTS Among 119 HCV-infected patients who received DCV/ASV treatment, 104 (87.3%) achieved an SVR. In the SVR group, DCV/ASV treatment improved several liver-related variables at 24 weeks after the completion of therapy. In patients with an SVR, the values of glucagon-like peptide 1 (GLP-1) and leptin were significantly increased at 24 weeks after completing direct-acting antiviral therapy. However, no significant change was observed in non-SVR patients, regardless of the receipt of direct-acting antiviral treatment. CONCLUSION Gastrointestinal hormones related to the dietary habit and/or appetite may be influenced by HCV elimination.

Abstract
The indications for immune checkpoint inhibitors (ICIs) have expanded to include carcinomas of various organs. However, as ICI therapy expands, the management of immune-related adverse events (irAEs) has become a problem. ICI-related pancreatitis and cholangitis are relatively rare irAEs. Although some patients with ICI-related pancreatitis and cholangitis are asymptomatic and do not require treatment, there have been reports of patients who did not respond to immunosuppressive therapy and died. Thus, the pathogenesis of ICI-related pancreatitis and cholangitis should be clarified immediately. Currently, the role of endoscopy in the diagnosis and treatment of inflammatory pancreatic and biliary duct diseases is becoming increasingly important. In this review, we summarize clinical characteristics as well as radiographic and endoscopic findings of ICI-related pancreatitis and cholangitis.

Abstract
Inflammatory pseudotumor (IPT) of the liver is a rare benign disease. IPTs generally develop as solitary nodules, and cases with multiple lesions are uncommon. We herein report a case of multiple IPTs of the liver that spontaneously regressed. A 70-year-old woman with a 10-year history of primary biliary cholangitis and rheumatoid arthritis visited our hospital to receive a periodic medical examination. Abdominal ultrasonography revealed multiple hypoechoic lesions, with a maximum size of 33 mm, in the liver. Contrast-enhanced computed tomography revealed low-attenuation areas in the liver with mild peripheral enhancement at the arterial and portal phases. We first suspected metastatic liver tumors, but fluorodeoxyglucose positron emission tomography, magnetic resonance imaging and contrast-enhanced ultrasonography suggested the tumors to be inconsistent with malignant nodules. A percutaneous biopsy showed shedding of liver cells and abundant fibrosis with infiltration of inflammatory cells. Given these findings, we diagnosed the multiple tumors as IPTs. After careful observation for two months, the tumors almost vanished spontaneously. Physicians should avoid a hasty diagnosis of multiple tumors based solely on a few clinical findings, and a careful assessment with various imaging modalities should be conducted.

Abstract
AIM The pathogenic process underlying the development of hepatocellular carcinoma (HCC) is not yet clear in patients with chronic hepatitis C virus who receive direct-acting antiviral therapy and achieve sustained virological response. This study investigated two risk factors for HCC in these patients; specifically, hepatic fibrosis and steatosis. METHODS A total of 355 patients in whom hepatitis C virus was eradicated by direct-acting antiviral were evaluated. Fibrosis and steatosis were assessed using transient elastography (TE) and the controlled attenuation parameter (CAP). Inverse probability weighting was applied to patient age, sex, albumin-bilirubin, α-fetoprotein, history of HCC, TE, or CAP. RESULTS The 12-, 24-, and 36-month cumulative incidence rates of HCC were 0.9%, 2.4%, and 4.1%, respectively. Univariate analysis with the Cox proportional hazards model showed that whereas a high TE value (≥10 kPa) was significantly associated with HCC development (HR 7.861, 95% CI 2.126-29.070; p = 0.002), CAP was not. Additionally, univariate analysis with the Cox proportional hazards model adjusted by inverse probability weighting showed that a high TE value was significantly associated with HCC development (HR 3.980, 95% CI, 1.036-15.290; p = 0.044), whereas CAP was not. The cumulative inverse probability weighting-adjusted incidence of HCC rates at 12, 24, and 36 months were 0.0%, 0.5%, and 1.7%, respectively, in patients with a low TE value, and 2.5%, 5.1%, and 7.6%, respectively, in those with a high TE value. CONCLUSION A high TE value was a risk factor for HCC in hepatitis C virus patients who received direct-acting antiviral therapy and achieved sustained virological response.

Abstract
BACKGROUND/AIM To elucidate factors associated with secular changes of grip strength (GS) in patients with chronic liver diseases (CLDs) (n=241, 102 males, median age=63 years, 87 liver cirrhosis cases). MATERIALS AND METHODS ΔGS (kg/year) was defined as [GS value (second time) - GS value (first time)]/[time interval between the first and second time]. GS loss (GSL) was defined as ΔGS <0 kg/year. RESULTS The median ΔGS in patients with non-LC, Child-Pugh A (n=70) and Child-Pugh B (n=17) were 0.3, -0.2 and -1.6 kg/year (overall p<0.0001). In the multivariate analysis of factors linked to the GSL for all cases, extracellular water (ECW) to total body water (TBW) ratio was significant (p=0.0007). In the multivariate analysis in male, no significant factor was found, while in female, ECW to TBW ratio was significant (p=0.0024). CONCLUSION Liver functional parameters can be closely linked to the GSL especially in female CLD patients.

Abstract
AIM To elucidate the common and different points between sarcopenia and frailty in chronic liver damage (CLD). PATIENTS AND METHODS Patients with both grip strength decline and skeletal muscle index decline were regarded as sarcopenia. Frailty was defined as a syndrome in which 3 or more of the following criteria were met: i) exhaustion, ii) body weight loss, iii) slow walking speed, iv) muscle weakness, and v) low physical activity. RESULTS Sarcopenia and frailty were identified in 52 patients (15.2%) and 46 (13.5%), respectively. The prevalence of sarcopenia and frailty was well stratified according to age and the liver cirrhosis (LC) status. In the multivariate analysis, we identified significant factors for sarcopenia: i) age, ii) LC, iii) body mass index and iv) extracellular water (ECW) to total body water (TBW) ratio, while only the ECW to TBW ratio was significant for frailty. CONCLUSION Sarcopenia and frailty in CLD should be separately evaluated.

Abstract
BACKGROUND/AIM To elucidate the influence of calf circumference (CC) on sarcopenia in patients with chronic liver damages (CLDs, n=525, 255 men). PATIENTS AND METHODS Anthropometry parameters including arm circumference, arm muscle circumference, CC, arm muscle area, triceps skinfold thickness, waist circumference and body mass index were measured. Patients with both grip strength (GS) decline and skeletal muscle index (SMI) decline were diagnosed as sarcopenic. RESULTS Liver cirrhosis was identified in 103 cases (40.4%) in males and 87 cases (32.2%) in females. Sarcopenia was identified in 23 male patients (9.0%) and 38 female patients (14.1%). CC had the strong positive correlation with SMI both in male (r=0.79, p<0.0001) and female (r=0.83, p<0.0001). Among the above mentioned 7 anthropometry parameters, CC had the highest area under the receiver operating characteristics curve (AUC) for sarcopenia both in males (AUC=0.88) and females (AUC=0.86). CONCLUSION CC can be helpful for predicting sarcopenia in CLDs.

Abstract
AIM Shear wave elastography (SWE) in patients with chronic liver diseases is a noninvasive useful method for the diagnosis of liver fibrosis severity, which can be an alternative to liver biopsy. However, the liver stiffness measurement using SWE can be affected by various factors including hepatic inflammation, extrahepatic cholestasis, heart failure, and underlying liver diseases. The aim of this study is to clarify the correlation between liver stiffness using SWE and hepatic necroinflammation serologically and pathologically. METHODS A total of 843 patients with chronic liver disease who received liver biopsy were analyzed. Liver stiffness measurement using transient elastography (TE) and virtual touch quantification (VTQ) were carried out on the same day as the liver biopsy. The correlation between SWE and hepatic inflammation was analyzed serologically and pathologically. RESULTS The liver stiffness values increased significantly with the progression of liver fibrosis and inflammation (overall p < 0.001). In patients with F0-1, F2, and F3, TE and VTQ values of A2 or A3 were significantly higher than those of A0 or A1 (p value, all <0.05), but not in patients with F4. The median alanine aminotransferase (ALT) values increased significantly with the progression of liver inflammation (p < 0.001). Moreover, TE and VTQ in patients with ALT ≥70 IU/L were significantly higher than those in patients with ALT <70 IU/L (p < 0.01), but not in patients with F4. CONCLUSION Shear wave elastography can be affected by hepatic necroinflammation in F0-F3 fibrosis, but not in F4.

A New Ultrasonographic "Fluttering Sign" for Hepatic Hemangioma. ULTRASOUND IN MEDICINE & BIOLOGY 2021; 47:941-946. [PMID: 33413966 DOI: 10.1016/j.ultrasmedbio.2020.12.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/22/2020] [Revised: 11/18/2020] [Accepted: 12/09/2020] [Indexed: 06/12/2023]
Abstract
The aim of the study described here was to clarify the diagnostic value of the fluttering sign, a new sign that characterizes hepatic hemangiomas in gray-scale ultrasonography (US). It refers to a phenomenon in which the speckled echogenicity inside the hemangioma changes continuously and seems to be moving. A total of 172 hemangiomas diagnosed with contrast-enhanced US were evaluated. The fluttering sign was found in 123 of 172 hemangiomas (71.5%). Its prevalence was significantly higher than that of the marginal strong echo (89/172, 51.7%, p < 0.001), posterior acoustic enhancement (103/172, 59.9%, p = 0.031) and chameleon sign (100/172, 58.1%, p = 0.013). In addition, the fluttering sign was observed significantly more frequently in mixed or hypo-echoic tumors than in hyper-echoic tumors (p < 0.001), relatively large tumors (p < 0.001) and tumors that were less than 5 cm from the body surface (p = 0.015). The fluttering sign in gray-scale US has great potential to be a new complementary sign for the diagnosis of hemangioma.

Reduced grip strength is associated with progression of depressive status in chronic liver diseases. ANNALS OF PALLIATIVE MEDICINE 2021; 10:3976-3987. [PMID: 33832301 DOI: 10.21037/apm-20-2059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/19/2020] [Accepted: 01/14/2021] [Indexed: 11/06/2022]
Abstract
BACKGROUND The causal relationship between sarcopenia and depression in chronic liver disease (CLD) patients is unclear. To elucidate these issues, we aimed to investigate the impacts of muscle strength as assessed by grip strength (GS) and muscle mass as assessed by bioelectrical impedance analysis (BIA) on the progression of depression in CLD patients (n=189, 49 cirrhotic cases, and 87 males). METHODS The Beck Depression Inventory-2nd edition (BDI-II) was used for the evaluation of depression. Time interval from the date of baseline BDI-II and the first confirmed date of elevation of BDI-II score was calculated in each subject. We analyzed factors associated with the elevation of BDI-II score. RESULTS The baseline mean BDI-II score was 8.4 (median value, 7). Depression (BDI-II score >11) was found in 63 patients (33.33%). GS decline at baseline was found in 13 male patients (14.9%) and 37 female patients (36.3%). Skeletal muscle index (SMI) by BIA decline at baseline was found in 25 male patients (28.7%) and 40 female patients (39.2%). During the follow-up period, 84 patients (44.4%) had the elevation of BDI-II score. For all cases, the 1-, 2- and 3-year cumulative elevation rates of BDI-II score were 39.2%, 46.6% and 54.9%. In patients with GS decline at baseline, the 1-, 2- and 3-year cumulative elevation rates of BDI-II score were 53.1%, 67.8% and 77.9%, while in patients with GS non-decline at baseline, the 1-, 2- and 3-year cumulative elevation rates of BDI-II score were 34.4%, 39.8% and 47.4% (P=0.0006). In patients with SMI decline at baseline, the 1-, 2- and 3-year cumulative elevation rates of BDI-II score were 43.5%, 50.8% and 62.1%, while in patients with SMI non-decline at baseline, the 1-, 2- and 3-year cumulative elevation rates of BDI-II score were 36.9%, 44.5% and 51.0% (P=0.2487). As per the multivariate analyses, only lower GS at baseline (P=0.0022) was identified to be a significant factor associated with the elevation of BDI-II score. CONCLUSIONS Reduced GS rather than loss of muscle mass can be independently associated with an elevated risk for the progression of depression.

Abstract
Abstract
Background
Fractional flow reserve (FFR) is one of most reliable index for the determining the functional severity coronary artery stenosis. Adenosine is the most commonly used agent for maximal hyperaemia. However, adenosine can cause chest discomfort, bronchial hyper-reactivity, and atrioventricular block. The aim of this study is to evaluate the safety and efficacy of intracoronary nicorandil as an alternative hyperaemic agent for FFR.
Methods and results
We enrolled consecutive 82 patients (87 lesions) who underwent FFR measurement in our center from Nov. 2018. We compared three groups; intravenous infusion of adenosine (150 μg/kg/min); and adenosine added intracoronary nicorandil 2mg; and intracoronary nicorandil 4mg. Mean FFR value was 0.83±0.09, 0.82±0.09, 0.82±0.08, There was a strong correlation among three groups (R2>0.9). Mean cyclic change in FFR was 0.026±0.023, 0.019±0.010, 0.016±0.014, respectively, cyclic change was smallest in intracoronary nicorandil 4mg group (vs ATP; p<0.001, vs ATP + nicorandil 2mg; p<0.001). By Wilcoxon test, mean FFR value of nicorandil 4mg was significant lower than ATP (p=0.0021), and equal to ATP + nicorandil 2mg (p=0.98).
Conclusions
Intracoronary nicorandil 4mg is a simple, safe, and effective way to induce steady-state hyperaemia for FFR.

[PMID: 32605049 PMCID: PMC7404642 DOI: 10.3390/medicina56070319] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2020] [Revised: 06/24/2020] [Accepted: 06/25/2020] [Indexed: 11/30/2022]
Abstract
Background and objectives: Few data with regard to the relevance between depression and frailty in chronic liver disease (CLD) patients are currently available. We aimed to elucidate the relationship between frailty and depression as evaluated by the Beck Depression Inventory—2nd edition (BDI-II) in CLD patients (n = 340, median age = 65.0 years). Methods: Frailty was defined as a clinical syndrome in which three or more of the following criteria were met: body weight loss, exhaustion, muscle weakness, slow walking speed and low physical activity. Depressive state was defined as BDI-II score 11 or greater. Results: Robust (frailty score = zero), prefrail (frailty score = one or two) and frailty were identified in 114 (33.5%), 182 (53.5%) and 44 (12.9%). The median BDI-II score was five. Depressive state was identified in 84 patients (24.7%). The median BDI-II scores in patients with robust, prefrail and frail traits were 2, 7 and 12.5 (robust vs. prefrail, p < 0.0001; prefrail vs. robust, p = 0.0003; robust vs. frail, p < 0.0001; overall p < 0.0001). The proportions of depressive state in patients with robust, prefrail and frail traits were 3.51%, 30.77% and 54.55% (robust vs. prefrail, p < 0.0001; prefrail vs. robust, p = 0.0046; robust vs. frail, p < 0.0001; overall p < 0.0001). BDI-II score significantly correlated with frailty score (rs = 0.5855, p < 0.0001). Conclusions: The close correlation between frailty and depression can be found in CLD. Preventing frailty in CLD should be approached both physiologically and psychologically.

Abstract
We sought to examine the serum zinc (Zn) level and frailty in patients with chronic liver diseases (CLDs, n = 285, 107 liver cirrhosis cases, median age = 66 years). Frailty was defined as a clinical syndrome in which three or more of the following criteria were met (frailty score 3, 4, or 5): unintentional body weight loss, self-reported exhaustion, muscle weakness (grip strength: <26 kg in men and <18 kg in women), slow walking speed (<1.0 m/s), and low physical activity. Robust (frailty score 0), prefrail (frailty score 1 or 2), and frailty were found in 90 (31.6%), 157 (55.1%), and 38 (13.3%), respectively. The median serum Zn levels in patients with frailty, prefrailty, and robust were 59.7 μg/dL, 72.8 μg/dL, and 76.9 μg/dL, respectively (p-values: frailty vs. prefrail, p < 0.0001; prefrail vs. robust, p = 0.0063; frailty vs. robust, p < 0.0001; overall p < 0.0001). For all cases, variables with absolute values of correlation coefficient with frailty score (0–5) ≥ 0.3 were age (rs = 0.3570, p < 0.0001), serum albumin (rs = −0.3212, p < 0.0001), extracellular water to total body water ratio using bioimpedance analysis (rs = 0.4386, p < 0.0001), and serum Zn level (rs = −0.3406, p < 0.0001). In conclusion, decreased serum Zn level in patients with CLDs can be closely associated with the presence of frailty.

Possible Relevance of PNPLA3 and TLL1 Gene Polymorphisms to the Efficacy of PEG-IFN Therapy for HBV-Infected Patients. Int J Mol Sci 2020; 21:ijms21093089. [PMID: 32349377 PMCID: PMC7247697 DOI: 10.3390/ijms21093089] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2020] [Revised: 04/22/2020] [Accepted: 04/24/2020] [Indexed: 12/14/2022] Open
Abstract
Lifestyle changes have led to an increase in the number of patients with nonalcoholic fatty liver disease (NAFLD). However, the effects of NAFLD-associated single-nucleotide gene polymorphisms (SNPs) in HBV-infected patients have not been adequately investigated. Methods: We investigated the association of the NAFLD-related SNPs patatin-like phospholipase domain-containing protein 3 (PNPLA3; rs738409), transmembrane 6 superfamily member 2 (TM6SF2; rs58542926), 17-beta hydroxysteroid dehydrogenase 13 (HSD17B13; rs72613567, rs6834314 and rs62305723), membrane-bound O-acyltransferase domain containing 7 (MBOAT7; rs641738) and glucokinase regulatory protein (GCKR; rs1260326) with the presence of histologically proven hepatic steatosis (HS) in HBV-infected patients (n = 224). We also investigated tolloid-like 1 (TLL1) SNP (rs17047200), which has been reported to be involved in the disease progression in Japanese NAFLD patients, and evaluated the association of HS and various SNPs with the treatment efficacy of pegylated-interferon (PEG-IFN) monotherapy following nucleotide/nucleoside (NA) treatment (NA/PEG-IFN sequential therapy; n = 64). Among NAFLD-associated SNPs evaluated, only the PNPLA3 SNP was significantly associated with the presence of hepatic steatosis in a total of 224 HBV-infected patients (P = 1.0 × 10−4). Regarding the sequential therapy, PNPLA3 SNP and TLL1 SNP were related to the treatment efficacy, and patients without minor alleles of these SNPs showed favorable results with a high virologic response and significant reduction in their HBsAg titer. A multivariate analysis showed that HBeAg positivity (odds ratio 5.810, p = 0.016) and the absence of a risk allele in PNPLA3 and TLL1 SNPs (odds ratio 8.664, p = 0.0042) were significantly associated with treatment efficacy. The PNPLA3 SNP might be associated with the presence of HS, and the combination of the PNPLA3 and TLL1 SNPs might be related to the efficacy of PEG-IFN monotherapy following NA treatment.

Abstract
Here we sought to clarify the prognostic impact of sarcopenia-related markers (grip strength (GS), muscle mass using bioimpedance analysis and patient quality of life as assessed by the 36-Item Short-Form Health Survey (SF36)) in patients with chronic liver diseases (CLDs, n = 411; 160 liver cirrhosis patients; median age, 64 years) on the incidence of composite hepatic events (CHEs). A GS decrease was defined as <26 kg in men and <18 kg in women, while a skeletal muscle mass index (SMI) decrease was defined as <7.0 kg/m2 in men and <5.7 kg/m2 in women based on the current guidelines. The physical and metal component summary scores on the SF36 were also included into the analysis. Sixty-two patients (15.1%) had the first incidence of CHEs. The three-year cumulative incidence rates of CHEs in patients with GS decrease or non-decrease were 24.51% and 12.44% (p = 0.0057). The three-year cumulative incidence rates of CHEs in patients with an SMI decrease or non-decrease were 19.65% and 12.99% (p = 0.0982). Multivariate analysis revealed that GS decrease (p = 0.0350) and prothrombin time (p = 0.0293) were significantly associated with the incidence of CHEs. In conclusion, GS can be an independent predictor for CHE development in patients with CLDs.

Abstract
We sought to clarify the correlation between non-protein respiratory quotient (npRQ) in indirect calorimetry and serum zinc (Zn) level in chronic liver diseases (CLDs, n = 586, 309 liver cirrhosis (LC) patients, median age = 63 years). Clinical parameters potentially linked to npRQ <0.85 (best cutoff point for the prognosis in LC patients) were also examined in receiver operating characteristic curve (ROC) analyses. The median npRQ was 0.86. The median serum Zn level was 64 μg/dL. The median npRQ in patients with non-LC, Child–Pugh A, Child–Pugh B and Child–Pugh C were 0.89, 0.85, 0.83 and 0.82 (overall p < 0.0001)). The median serum Zn level in patients with npRQ <0.85 (58 μg/dL) was significantly lower than that in patients with npRQ ≥ 0.85 (68 μg/dL) (p < 0.0001). The correlation coefficient (r) between npRQ level and serum Zn level for all cases was 0.40 (p < 0.0001). Similar tendencies were observed in all subgroup analyses. The highest correlation coefficient between serum Zn level and npRQ was found in patients with Child–Pugh C (n = 22, r = 0.69). In ROC analyses for npRQ <0.85, serum Zn level had the highest area under the ROC (AUC) among baseline laboratory parameters (AUC = 0.69). In conclusion, serum Zn level can be helpful for npRQ in patients with CLDs.

Abstract
We aim to clarify the impact of walking speed (WS) and analyze factors linked to WS decline in patients with chronic liver diseases (CLDs, 165 males and 191 females, 137 liver cirrhosis patients). The WS decline is defined as <0.8 m/second (m/s), referring to the guidelines. The median (range) WS was 1.3 m/s (0.2–2.02 m/s). There were 17 patients with WS < 0.8 m/s (4.8%). The WS value was significantly correlated with the handgrip strength value both in males (r2 = 0.252, p < 0.0001) and females (r2 = 0.256, p < 0.0001). In the multivariate analysis of factors associated with WS decline, only the extracellular water (ECW) to total body water (TBW) ratio using bioimpedance analysis was an independent predictor (p = 0.0398). Extracellular fluid excess was categorized as follows: normal condition (ECW to TBW ratio < 0.390), mild overhydrated condition (ECW to TBW ratio 0.390–0.399), and moderate to severe overhydrated condition (ECW to TBW ratio ≥ 0.400). The WS value was well stratified according to the ECW to TBW ratio (normal vs. mild, p = 0.0001; mild vs. moderate to severe, p < 0.0001; normal vs. moderate to severe, p < 0.0001; overall p-value < 0.0001). In conclusion, the ECW to TBW ratio can be closely linked to WS decline in CLD patients.

Abstract
Health related quality of life (HRQOL) in chronic liver disease (CLD) patients has been attracting much attention these days because it is closely associated with clinical outcomes in CLD patients. HRQOL has become established as an important concept and target for research and practice in the fields of medicine. A critique of HRQOL research is the lack of conceptual clarity and a common definition of HRQOL. Using a clear definition of HRQOL may increase the conceptual understanding. In this study, we aimed to elucidate the association between serum zinc (Zn) level and HRQOL as assessed by the Beck Depression Inventory-2nd edition (BDI-II), Pittsburgh Sleep Quality Index Japanese version (PSQI-J) and the 36-Item Short Form Health Survey (SF-36) in CLD patients (n = 322, median age = 65 years, 121 liver cirrhosis (LC) patients (37.6%)). The median serum Zn level for all cases was 73.2 μg/dl. The median BDI-II score and PSQI-J score were 6 and 5, respectively. Patients with higher BDI-II score tended to have lower serum Zn level compared with those with lower BDI-II score. Similar tendencies were observed in patients with higher PSQI-J score. In the SF-36, physical functioning, role physical and physical component summary score significantly correlated with serum Zn level regardless of age, liver disease etiology and the LC status. While mental health and mental component summary score did not significantly correlate with serum Zn level regardless of age, liver disease etiology and the LC status. In conclusion, serum Zn level can be a useful marker for decreased HRQOL in patients with CLDs, especially for physical components.

Abstract
We aimed to compare the impact on survival among albumin-bilirubin (ALBI) grade, modified ALBI (mALBI) and our proposed combined ALBI grade and Mac-2 binding protein glycosylation isomer (M2BPGi) or FIB4 index grading system in chronic hepatitis C (CHC) related compensated liver cirrhosis (n = 165, 93 men and 72 women, median age = 67 years). Patients with ALBI grade 1, 2, and 3 were allocated a score of 1, 2, and 3 points, respectively. Patients with mALBI grade 1, 2A, and 2B were allocated a score of 1, 2, and 3 points, respectively. Patients with a high or low M2BPGi were allocated a score of 1 and 0 point. Patients with a high or low FIB4 index were allocated a score of 1 and 0 point. Sum of the point of ALBI (1, 2, or 3) and M2BPGi (0 or 1) or FIB4 index (0 or 1) was defined as ALBI-M2BPGi grade or ALBI-FIB4 grade. Prognostic accuracy was compared using the Akaike information criterion (AIC) value and time dependent receiver operating characteristics (ROC) curve analysis. The median follow-up duration was 5.422 years. AIC value for survival by ALBI-M2BPGi grade was the lowest among 4 prognostic models (AIC: 205.731 in ALBI grade, 200.913 in mALBI grade, 189.816 in ALBI-M2BPGi grade, and 204.671 in ALBI-FIB4 grade). All area under the ROC curves of ALBI-M2BPGi grade in each time point were higher than those of ALBI grade, mALBI grade, and ALBI-FIB4 grade. In conclusion, our proposed ALBI-M2BPGi grading system seems to be helpful for estimating prognosis in patients with CHC related compensated LC.

Abstract
We investigated the diagnostic capability of the proprietary attenuation imaging (ATI) modality found on some Canon Medical Systems Corp. ultrasound scanners to detect histologically diagnosed steatosis in 148 patients. ATI values increased significantly with increasing steatosis grade (p < 0.001). The diagnostic values (area under the receiver operating characteristic curve) of ATI for steatosis grades ≥ 1 (5%-33% of hepatocytes), ≥ 2 (33%-66% of hepatocytes) and 3 (> 66% of hepatocytes) were 0.85, 0.91 and 0.91. In addition, ATI values increased significantly with increasing steatosis grades (p = 0.002) even in obese patients (n = 41). The diagnostic values of ATI for steatosis grades ≥ 1, ≥ 2 and 3 in obese patients were 0.72, 0.72 and 0.78. Furthermore, ATI values increased significantly with increasing steatosis grade (p < 0.001) in patients with non-alcoholic fatty liver disease (NAFLD) (n = 38). The diagnostic values of ATI for steatosis grades ≥ 1, ≥ 2 and 3 in NAFLD patients were 0.77, 0.88 and 0.86. In conclusion, the ATI method showed good diagnostic capability for the detection of hepatic steatosis.

We sought to compare the impact upon grip strength (GS) between the Mac-2 binding protein glycosylation isomer (M2BPGi) and the Fibrosis-4 (FIB4) index in chronic liver disease (CLD) patients (n = 376: 171 males and 205 females, and 137 liver cirrhosis (LC) cases (36.4%)). Factors linked to the low GS (<26 kg in male and <18 kg in female) were also investigated using univariate and multivariate analyses. The median GS in males was 35.5 kg, while that in females was 21.1 kg. The median M2BPGi was 1.11 cutoff index, whereas the median FIB4 index was 2.069. In both male (P < 0.0001) and female (P = 0.0001), GS in LC patients was significantly lower than that in non-LC patients. In males, M2BPGi (r = −0.4611, P < 0.0001) and the FIB4 index (r = −0.4556, P < 0.0001) significantly correlated with GS. Similarly, in females, M2BPGi (r = −0.33326, P < 0.0001) and our FIB4 index (r = −0.26388, P = 0.0001) also significantly correlated with GS. In the multivariate analyses of factors linked to the low GS, independent factors were: M2BPGi (P = 0.0003) and skeletal muscle index (P = 0.0007) in males, and age (P < 0.0001) and serum albumin level (P = 0.0484) in females. In conclusion, liver fibrosis markers were well-correlated with GS in CLD patients. In particular, M2BPGi can be helpful for predicting the low GS in male patients.

Liver fibrosis markers as assessed by ultrasound elastography and serum samples: A large comparative study in hepatitis virus B and C liver diseases. Hepatol Res 2019; 49:721-730. [PMID: 30884015 DOI: 10.1111/hepr.13332] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/26/2018] [Revised: 02/23/2019] [Accepted: 03/10/2019] [Indexed: 12/12/2022]
Abstract
AIM We aimed to compare the well-established liver fibrosis (LF) markers in Japanese patients with chronic hepatitis B (CHB, n = 331) and chronic hepatitis C (CHC, n = 886) and to discuss possible causes of differences in results between CHB patients and CHC patients. METHODS Virtual touch quantification (VTQ) in acoustic radiation force impulse, Fibrosis-4 (Fib-4) index, aspartate aminotransferase to platelet ratio index (APRI), and hyaluronic acid (HA) were compared between the two cohorts. As an additional investigation, total collagen proportional area (TCPA, %) was tested using liver pathological samples (n = 83). RESULTS Significant LF (F2 or greater) and advanced LF (F3 or greater) were identified in 153 (46.2%) and 76 (23.0%) patients in the CHB cohort and 579 (65.3%) and 396 (44.7%) patients in the CHC cohort. The median VTQ, Fib-4 index, APRI, and HA values in the CHB cohort were 1.20 m/s, 1.36, 0.44, and 25 ng/mL; those in the CHC cohort were 1.32 m/s, 2.60, 0.74, and 65.5 ng/mL (P-values, all <0.0001). Similar tendencies were noted by F stage-based stratification. The median TCPA in the CHB cohort and the CHC cohort were 8.5% and 12.7% (P < 0.0006). The TCPA values in the CHC cohort were higher than those in the CHB cohort regardless of LF stage. CONCLUSION Values of LF markers in CHB patients can differ from those in CHC patients even in the same LF stage. Difference in total amount of collagen fiber in CHB and CHC appears to be linked to the difference.

Elevated levels of circulating ITIH4 are associated with hepatocellular carcinoma with nonalcoholic fatty liver disease: from pig model to human study. BMC Cancer 2019; 19:621. [PMID: 31238892 PMCID: PMC6591942 DOI: 10.1186/s12885-019-5825-8] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2019] [Accepted: 06/12/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Noninvasive biomarkers are urgently needed for optimal management of nonalcoholic fatty liver disease (NAFLD) for the prevention of disease progression into nonalcoholic steatohepatitis (NASH) and hepatocellular carcinoma (HCC). In order to identify the biomarkers, we generated the swine hepatocellular carcinoma (HCC) model associated with NAFLD and performed serum proteomics on the model. METHODS Microminipigs were fed a high-fat diet to induce NAFLD and a normal diet as the control. To induce HCC, diethylnitrosamine was intraperitoneally administered. Biopsied liver samples were histopathologically analyzed every 12 weeks. Serum proteins were separated by blue native two-dimensional gel electrophoresis and proteins of interest were subsequently identified by MALDI-TOF MS/MS. Human serum samples were analyzed to validate the candidate protein using antibody-mediated characterization. RESULTS In the NAFLD pigs, hepatic histology of nonalcoholic steatohepatitis (NASH) was observed at 36 weeks, and HCC developed at 60 weeks. Among serum proteins identified with MALDI-TOF MS/MS, serum inter-alpha-trypsin inhibitor heavy chain 4 (ITIH4), an acute response protein which is secreted primarily by liver, was identified as the most characteristic protein corresponding with NAFLD progression and HCC development in the NAFLD pigs. With immunoassay, serum ITIH4 levels in the NAFLD pigs were chronologically increased in comparison with those in control animal. Furthermore, immunohistochemistry showed ITIH4 expression in hepatocytes also increased in both the cancer lesions and parenchyma as NAFLD progressed. Human study is also consistent with this observation because serum ITIH4 levels were significantly higher in HCC-NAFLD patients than in the simple steatosis, NASH, and virus-related HCC patients. Of note, HCC-NAFLD patients who had higher serum ITIH4 levels exhibited poorer prognosis after hepatectomy. CONCLUSIONS We established an HCC pig model associated with NAFLD. Serum proteomics on the swine HCC with NAFLD model implicated ITIH4 as a non-invasive biomarker reflecting NAFLD progression as well as subsequent HCC development. Most importantly, the results in the swine study have been validated in human cohort studies. Dissecting speciation of serum ITIH4 promises to have clinical utility in monitoring the disease.

Comparison of liver stiffness assessment by transient elastography and shear wave elastography using six ultrasound devices. Hepatol Res 2019; 49:676-686. [PMID: 30680865 DOI: 10.1111/hepr.13319] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2018] [Revised: 01/06/2019] [Accepted: 01/22/2019] [Indexed: 02/08/2023]
Abstract
AIM Transient elastography (TE) is the gold standard for measurement of liver stiffness. The usefulness of shear wave elastographies (SWE) is well accepted. However, the measurement values cannot be equivalently compared because cut-off values for the diagnosis of liver fibrosis are different among those devices. We aimed to clarify correlations, to generate the regression equations between TE and SWEs, and to compare the diagnostic ability of each device to diagnose liver fibrosis. METHODS A total of 109 patients with chronic liver disease who underwent liver biopsy and same-day evaluation of liver stiffness using six ultrasound devices were analyzed. The diagnostic ability of liver stiffness from each ultrasound device and correlations between TE and each SWE were analyzed. RESULTS Liver stiffness measured by all six ultrasound devices increased significantly as liver fibrosis stage advanced (P < 0.001). Receiver operating characteristic (ROC) curve analysis for predicting significant fibrosis (≥F2) and cirrhosis yielded area under the ROC curve (AUROC) values based on TE of 0.830 (95% confidence interval [CI], 0.755-0.905) and 0.959 (95% CI, 0.924-0.995), respectively. The AUROCs for predicting significant fibrosis (≥F2) and cirrhosis (F4) based on SWE from all five ultrasound devices were over 0.8 and 0.9, respectively. Furthermore, the correlation coefficients between TE values and SWE values from five ultrasound devices were all over 0.8, indicating a strong relationship. CONCLUSION Our study showed strong correlations between TE and SWEs with high correlation coefficients. The regression equations between TE and SWEs demonstrated the ability to compare the measurement values in each device equivalently.

Serum Zinc Concentration and Sarcopenia: A Close Linkage in Chronic Liver Diseases. J Clin Med 2019; 8:jcm8030336. [PMID: 30862022 PMCID: PMC6462961 DOI: 10.3390/jcm8030336] [Citation(s) in RCA: 27] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2019] [Revised: 03/07/2019] [Accepted: 03/07/2019] [Indexed: 12/17/2022] Open
Abstract
We sought to investigate the influence of serum zinc (Zn) concentration on sarcopenia in chronic liver diseases (CLDs, n = 372, median age = 65 years, 147 liver cirrhosis (LC) cases (39.5%)). Sarcopenia was defined by low grip strength and low skeletal muscle mass. Study subjects were divided into the following three groups (High-, Intermediate-, and Low-Zn groups) based on the baseline serum Zn level. The impacts of serum Zn concentration on sarcopenia were examined. The median (interquartile range) serum Zn concentration for all cases was 72.85 (63.7, 81.45) μg/dL. The proportions of sarcopenia in the High-Zn, Intermediate-Zn, and Low-Zn groups were 10.75% (10/93), 11.23% (21/187), and 27.17% (25/92), respectively (P = 0.9046 (High vs. Intermediate), P = 0.0007 (Intermediate vs. Low), P = 0.0044 (High vs. Low), overall P value = 0.0009). The median serum Zn concentrations in patients with sarcopenia, pre-sarcopenia, and control were 66.35, 73.1 and 73.8 μg/dL, respectively (P = 0.0234 (sarcopenia vs. pre-sarcopenia), P = 0.2116 (pre-sarcopenia vs. control), P = 0.0002 (sarcopenia vs. control), overall P value = 0.0016). In the multivariate analyses of factors linked to the presence of sarcopenia, Low-Zn was an independent predictor for all cases (P = 0.0236) and LC cases (P = 0.0082). In conclusion, Zn deficiency can be an independent predictor for sarcopenia in patients with CLDs.

Proposed model for the prediction of intrahepatic covalently closed circular DNA level in patients with chronic hepatitis B. Hepatol Res 2019; 49:271-283. [PMID: 30358027 DOI: 10.1111/hepr.13280] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2018] [Revised: 10/04/2018] [Accepted: 10/19/2018] [Indexed: 02/08/2023]
Abstract
AIM We sought to create a prediction model for intrahepatic covalently closed circular DNA (IH-cccDNA) level in chronic hepatitis B (CHB) patients and to validate the model's predictive accuracy. METHODS Patients who did not receive previous nucleoside analogue (NA) therapy were assigned to the training cohort (n = 57), and those who received previous NA therapy were assigned to the validation cohort (n = 69). Factors linked to IH-cccDNA levels in the training cohort were analyzed and a formula to predict IH-cccDNA levels was constructed. Next, the reproducibility of that formula was assessed. RESULTS In the multivariate analysis for the prediction of IH-cccDNA level in the training cohort, fasting blood sugar (FBS) (P = 0.0227), hepatitis B e antigen (HBeAg) (P = 0.0067) and log10 (HB surface antigen [HBsAg]) (P = 0.0497) were significant, whereas HB core-related antigen (HBcrAg) tended to be significant (P = 0.0562). The formula was constructed and named the FBS-cres score based on the variables used (FBS, HBcrAg, HBeAg, and HBsAg). The FBS-cres score was calculated as: 3.1686 - (0.0148 × FBS) + (0.1982 × HBcrAg) + (0.0008168 × HBeAg) + (0.1761 × log10 (HBsAg)). In the training cohort, a significant correlation was noted between HBcrAg and IH-cccDNA levels (P < 0.0001, r = 0.67), whereas the FBS-cres score was more closely correlated to IH-cccDNA level (P < 0.0001, r = 0.81). In the validation cohort, significant correlation was found between HBcrAg and IH-cccDNA levels (P = 0.0012, r = 0.38), whereas the FBS-cres score was more closely linked to IH-cccDNA levels (P < 0.0001, r = 0.51). Similar tendencies were observed in all subgroup analyses. CONCLUSION Our proposed model for the prediction of IH-cccDNA level could be helpful in CHB patients.

Abstract
We sought to investigate the influence of sarcopenia as defined by muscle strength and skeletal muscle mass (SMM) on sleep disturbance as evaluated by the Japanese version of Pittsburgh Sleep Quality Index (PSQI-J) in chronic liver diseases (CLDs) (n = 419). Muscle strength and muscle mass were determined by grip strength (GS) and SMM using bioimpedance analysis. Patients were classified into four types: type A (n = 61); decreased GS and decreased SMM; type B (n = 45); decreased GS and non-decreased SMM; type C (n = 102); non-decreased GS and decreased SMM; and type D (n = 211); non-decreased GS and non-decreased SMM. Factors associated with PSQI-J score 6 or more were examined. PSQI-J score 0–5 (normal) was found in 253 (60.4%); 6–8 (mild) in 97 (23.2%); 9–11 (moderate) in 45 (10.7%) and 12 or more (severe) in 24 (5.7%). Univariate analysis identified three factors to be significantly associated with PSQI-J score 6 or more: presence of liver cirrhosis (LC) (P = 0.0132); our classification of type A; B; C and D (P < 0.0001) and serum albumin level (P = 0.0041). Multivariate analysis showed that type A (P = 0.0021) and type B (P = 0.0220) were significant independent factors. In conclusion, sarcopenia in CLDs appears to be closely associated with sleep disturbance mainly due to muscle strength decline.

Abstract
We sought to examine the influence of hand grip strength (HGS) and skeletal muscle mass (SMM) on the health-related quality of life (H-QOL) as evaluated by the 36-Item Short-Form Health Survey (SF-36) questionnaire in chronic liver diseases (CLDs, 198 men and 191 women). Decreased HGS was defined as HGS <26 kg for men and <18 kg for women. Decreased SMM was defined as SMM index <7.0 kg/m² for men and <5.7 kg/m² for women, using bioimpedance analysis. SF-36 scores were compared between groups stratified by HGS or SMM. Between-group differences (decreased HGS vs. non-decreased HGS) in the items of physical functioning (PF), role physical (RP), bodily pain, vitality (VT), social functioning (SF), role emotional (RE), and physical component summary score (PCS) reached significance, while between-group differences (decreased SMM vs. non-decreased SMM) in the items of PF, SF and RE were significant. Multivariate analyses revealed that HGS was significantly linked to PF (p = 0.0031), RP (p = 0.0185), and PCS (p = 0.0421) in males, and PF (p = 0.0034), VT (p = 0.0150), RE (p = 0.0422), and PCS (p = 0.0191) in females. HGS had a strong influence especially in the physiological domains in SF-36 in CLDs.

Association of the Body Mass Index with the Presence of Gastroesophageal Varices in Compensated Cirrhotic Patients with Hepatitis C Viral Infection. ANNALS OF CLINICAL AND LABORATORY SCIENCE 2018; 48:801-804.

Abstract
Obesity is regarded as a risk factor for various benign and malignant diseases. We evaluated whether or not the body mass index (BMI) was associated with the presence of gastroesophageal varices in asymptomatic hepatitis C virus (HCV)-related compensated cirrhosis (Child-Pugh grade A status). Among a total of 794 patients of HCV-related chronic liver disease, 90 had histologically-proven cirrhosis, and 63 were classified as having compensated cirrhosis (30 had varices, and the remaining 33 did not). The values of prothrombin time (%) and platelet count were significantly lower in the patients with varices than in those without (P=0.042 and P=0.013, respectively). In addition to the abovementioned variables, the BMI was significantly higher in the patients with varices than in those without (P=0.031). In a multivariate analysis, only an increased BMI (odds ratio 1.205, 95% confidence interval 1.009-1.486, P=0.039) was independently associated with the presence of varices. In asymptomatic HCV-related compensated cirrhosis with a Child-Pugh A status, an increased BMI is suggested to be related to the presence of gastroesophageal varices.

Abstract
AIM Spleen stiffness is increased in liver cirrhosis (LC). We attempted to characterize the pathological features of spleen in LC. METHODS We compared pathological findings of resected spleen tissues of 28 LC patients and those of six healthy controls. In addition, we measured spleen stiffness before splenectomy by shear wave elastography in nine LC patients. After splenectomy, we examined the relationship between spleen stiffness and pathological findings. RESULTS Passive congestion of the spleen was more frequently observed in LC patients than in controls (P < 0.01). The sinus was wider in LC patients than in controls (P < 0.01). In the spleens of the LC patients, diffuse α-smooth muscle actin (αSMA) expression of sinusoidal mesenchymal cells and deposition of collagen fibers on the perisinusoidal wall were observed. In nine LC patients whose spleen stiffness was examined, the width of the sinus increased along with spleen stiffness (r = 0.89, P < 0.01). Spleen stiffness was higher in the spleen tissues with diffuse αSMA expression of sinusoidal mesenchymal cells than in those with partial αSMA expression of sinusoidal mesenchymal cells (P = 0.01). The degree of fibrosis was higher in the LC patients with diffuse αSMA expression of the red pulp than in those with partial αSMA expression of the red pulp (P = 0.03). CONCLUSION In the LC patients, spleen tissues showed passive congestion with a dilated sinus, diffuse αSMA expression of sinusoidal mesenchymal cells, and deposition of collagen fibers on the perisinusoidal wall. This contributed to spleen stiffness.

Abstract
Background Evaluating the progression of hepatic fibrosis in chronic hepatitis C (CHC) is critical, and identifying a predictive biomarker for fibrosis will be helpful for implementing personalized surveillance of hepatocellular carcinoma after the elimination of hepatitis C virus by antiviral therapy. This study aimed to investigate the association of circulating let-7a-5p levels with severity of hepatic fibrosis. Methods We analyzed circulating let-7a-5p levels in serum and serum-derived extracellular vesicles (EVs) in 84 Japanese CHC patients who underwent a liver biopsy by quantitative real-time polymerase chain reaction, and investigated the association of its levels with histological hepatic fibrotic stage, liver stiffness, and several hepatic fibrotic markers. Results The levels of let-7a-5p in serum and EVs were significantly lower in patients with liver cirrhosis. Additionally, the serum let-7a-5p level correlated significantly with hepatic fibrotic markers, Mac-2 binding protein glycan isomer (M2BPGi), fibrosis-4 (FIB-4) index, aspartate aminotransferase-to-platelet ratio index (APRI), and liver stiffness, evaluated by transient elastography. Furthermore, the serum let-7a-5p level was superior to M2BPGi, FIB-4, and APRI and was comparable to liver stiffness in discriminating liver cirrhosis. Conclusions These results provide evidence that circulating let-7a-5p in serum may serve as a surrogate marker for severity of hepatic fibrosis in CHC.

Abstract
Aims: To investigate the relationship between extracellular water to total body water ratio (ECW/TBW) in bioimpedance analysis (BIA) and clinical parameters in hepatitis viruses related to liver diseases. Methods: ECW/TBW was compared in patients with hepatitis B virus (HBV, n = 85) and hepatitis C virus (HCV, n = 440) related liver diseases. We also examined factors linked to mild to severe overhydrated state (ECW/TBW ≥0.4). Results: The median ECW/TBW in the HCV group was 0.388 (range, 0.365–0.433), while that in the HBV group was 0.381 (range, 0.363–0.425) (p < 0.0001). In all cases (n = 525), for predicting F3 or more, ECW/TBW yielded the area under the receiver operating characteristics (AUROC, 0.74912) and for predicting F4, ECW/TBW yielded the AUROC (0.75517). Multivariate analysis showed that age, prothrombin time, serum albumin, and alanine aminotransferase were significant factors linked to ECW/TBW ≥0.4. In patients with FIB-4 index <2, ECW/TBW in the HCV group was significantly higher than that in the HBV group (p = 0.0188), while in patients with 2 ≤ FIB-4 index <4 and FIB-4 index ≥4, the difference in the two groups did not reach significance. Conclusion: ECW/TBW can be different according to hepatitis viruses. Overhydrated status can easily occur in the HCV group even in the non-LC status compared with the HBV group.

Abstract
Due to varying positive rates of polymerase chain reaction (PCR) amplification, interpretation of conventional PCR results for non-infectious ascites remains problematic. The present study developed a highly sensitive PCR protocol and investigated the positive rate of PCR for the 16S ribosomal (r)RNA gene in non-infectious ascites. Following the design of a new PCR primer pair for the 16S rRNA gene (800F and 1400R), the sequences of PCR products were analyzed and the lower limit for bacterial DNA detection evaluated. The positive rate of PCR for 16S rRNA gene in non-infectious ascites was also evaluated. PCR with the primer pair amplified the genomic DNA of 16S rRNA genes of major disease-causing bacterial strains. Additionally, PCR with this primer pair provided highly sensitive detection of bacterial genomic DNA (lower limit, 0.1 pg of template DNA). When DNA samples isolated from ascites were used, the 16S rRNA gene was amplified independently of the presence of bacterial infection. PCR products contained the genomic DNA fragments of multiple bacterial species. Bacterial genomic DNA can be amplified from all ascitic fluids using a highly sensitive PCR protocol. Careful attention is required to interpret the results based on simple amplification of 16S rRNA gene with conventional PCR.

Abstract
Introduction and purpose Patients with pancreatic cancer (PC) have long been known to have high rates of depression. Depression in patients with PC can be linked to sleep disturbance. The American College of Sports Medicine notes that physical exercise is safe for most patients with cancer and physical inactivity should be avoided. However, clinical impacts of exercise interventions (EIs) on patients with PC have been poorly investigated. We aim to prospectively examine the effect of EIs on sleep disturbance in patients with PC using actigraphy, which is an objective measurement of motor activity and sleep. Methods and analysis This trial is a non-double blind randomised controlled trial. Standard therapy for each patient with PC will be allowed. When registering study subjects, a thorough assessment of the nutritional status and the daily physical activities performed will be undertaken individually for each participant. Study subjects will be randomly assigned into two groups: (1) the EI and standard therapy group or (2) the standard therapy group. In the EI and standard therapy group, physical activities equal to or higher than walking for 60 min/day will be strongly recommended. The primary outcome measure is the sleep-related variable using actigraphy (activity index) at 12 weeks. Ethics and dissemination The trial received approval from the Institutional Review Board at Hyogo College of Medicine (approval no. 2769). Final data will be publicly announced. A report releasing the study findings will be submitted for publication to an appropriate peer-reviewed journal. Trial registration number UMIN000029272; Pre-results.

Abstract
Introduction In most chronic pancreatitis (CP) cases, malabsorption, pain, and weight loss are the leading clinical symptoms, which significantly worsen the quality of life (QOL) and decreased QOL in patients with CP can cause sleep disorder. There is a growing body of evidence that recognises the favourable effects of physical exercise (PE), however, there are limited data currently available concerning patients with CP undergoing PE. Actigram is a device for gathering objective sleep/awake data in the natural sleeping surroundings over an extended time period. In this study, we will aim to prospectively investigate the effect of PE on sleep disorder as assessed by actigram in patients with CP. Methods and analysis This study is a non-double-blind randomised controlled trial. Study participants will be randomised into the PE group and the control group. When registering patients, precise assessment for nutritional status and daily physical activities will be undertaken in each study patient. In the PE group, physical activities equal to or higher than walking for 60 min/day should be strongly recommended. Sleep quality using actigram will be prospectively compared in the two groups. The primary endpoint is the activity index in actigram at 12 weeks. Ethics and dissemination Ethical approval for the study was granted by the Institutional Review Board at Hyogo College of Medicine (approval number 2767). Results will be presented at relevant conferences and submitted to an appropriate journal following trial closure and analysis.

Abstract
Introduction and purpose Sarcopenia is defined as a decrease in muscle mass and muscle strength, and it has been demonstrated to be an adverse predictor in numerous types of cancers. Exercise therapy (ET) carries multiple health benefits in several diseases. Despite these clinical benefits, there are limited data available regarding patients with pancreatic cancer (PC) undergoing ET. We aim to prospectively examine the effect of ET on sarcopenia in patients with PC. Methods and analysis All clinical stages of PC can be included. When registering study subjects, a precise evaluation of the nutritional status and the daily physical activities performed will be undertaken individually, for each participant. Study participants will be randomly allocated into two groups: (1) the ET and standard therapy group and (2) the standard therapy group. Amelioration of sarcopenia at 3 months postrandomisation will be the primary endpoint. Muscle mass will be calculated using bioimpedance analysis. Sarcopenia will be defined based on the current Asian guidelines. Participants will be instructed to perform exercises with > 3 metabolic equivalents (mets; energy consumption in physical activities/resting metabolic rate) for 60 min/day and to perform exercises with > 23 mets/week. In the ET group, physical activities equal to or greater than walking for 60 min/day will be strongly recommended. Ethics and dissemination The Institutional Review Board at Hyogo College of Medicine has approved this study protocol (approval no. 2772). The final data will be publicly announced. A report releasing the study results will be submitted for publication. Trial registration number UMIN000029271; Pre-results.

Abstract
Introduction and purpose Chronic pancreatitis (CP) involves progressive inflammatory changes to the pancreas and can lead to permanent structural damage and impairment of both endocrine and exocrine functions. Current reports highlight a rise in the incidence and prevalence of CP. However, there is limited data currently available concerning patients with CP undergoing exercise therapy (ET). We aim to prospectively examine the influence of ET on sarcopenia in patients with CP. Methods and analysis A detailed evaluation of the nutritional condition and the daily physical activities of each participant will be conducted prior to entering the study. Our patients will be randomly allocated to either: (1) the ET group or (2) the control group. In the ET group, our patients with CP will receive nutritional guidance once a month. The patients with CP will also be instructed to perform exercises with >3 metabolic equivalents (mets; energy consumption in physical activities/resting metabolic rate) for 60 min/day and to perform exercises >23 mets/week. The primary end point will be an improvement in sarcopenia, defined as an increase in muscle mass and muscle strength, at 3 months postrandomisation. A comparison of the amelioration of sarcopenia in the two groups will be undertaken. Ethics and dissemination The Institutional Review Board at Hyogo College of Medicine approved this study protocol (approval no. 2766). Final data will be publicly announced. A report releasing the study results will be submitted for publication to an appropriate journal. Trial registration number UMIN000029263; Pre-results. No patient is registered at the submission of our manuscript.

Abstract
Introduction Limited data are currently available for patients with overt hepatic encephalopathy (OHE)) receiving physical exercise (PE). The aim of the current study is to prospectively examine the effect of PE on sarcopaenia in patients with OHE. Methods and analysis At the time of patient recruitment, a precise assessment for nutritional status and daily physical activities will be performed in each subject. Study participants will be randomly assigned into two groups: (1) the PE group and (2) the control group. In the PE group, we will conduct guidance to study participants once a month at the outpatient nutrition guidance room. We will also instruct them to do exercise with >3 metabolic equivalents (mets; energy consumption in physical activities/resting metabolic rate) for 60 min per day and to do exercise >23 mets per week. Improvement of sarcopaenia as defined by muscle mass and muscle strength at 3 months after the randomisation will be the primary endpoint. Sarcopaenia will be defined based on the current Japanese guidelines. We prospectively compared the improvement of sarcopaenia in the two groups. Ethics and dissemination This study has received approval from the Institutional Review Board at Hyogo college of medicine (approval no. 2768). Final data will be publicly disseminated irrespective of the study results. A report releasing study results will be submitted for publication in an appropriate journal after completion of data collection. Trial registration number UMIN000029248; Pre-results.

Abstract
We aimed to elucidate the relationship between serum liver fibrosis markers (Mac-2 binding protein glycosylation isomer (M2BPGi), FIB-4 index, aspartate aminotransferase to platelet ratio index and hyaluronic acid), and skeletal muscle mass and to investigate factors linked to skeletal muscle mass loss (SMML) in patients with chronic hepatitis C (CHC, n = 277, median age = 64 years). We defined patients with psoas muscle index [PMI, sum of bilateral psoas muscle mass calculated by manual trace method at the lumber 3 level on the computed tomography images divided by height squared (cm/m)] less than 6.36 cm/m for male and 3.92 cm/m for female as those with SMML based on the recommendations in current guidelines. Receiver operating curve (ROC) analysis was performed for predicting SMML in 4 liver fibrosis markers and parameters linked to SMML were also investigated in the univariate and multivariate analyses. In terms of liver fibrosis stages, F4 was observed in 115 patients, F3 in 67, F2 in 38, F1 in 53, and F0 in 4. The median (range) PMI for male and female were 6.198 (2.999-13.698) and 4.100 (1.691-7.052) cm/m, respectively. There were 72 male patients with SMML (55.4%) and 58 female patients with SMML (39.5%) (P = .0112). In both male and female, a significant inverse correlation between PMI and levels of liver fibrosis markers was observed in all liver fibrosis markers. ROC analyses for predicting SMML revealed that FIB-4 index had the highest area under the ROC (AUC = 0.712), followed by M2BPGi (AUC = 0.692). In the multivariate analysis of factors linked to SMML, gender (P = .0003), body mass index (P < .0001), FIB-4 index (P = .0039), and M2BPGi (P = .0121) were found to be significant predictors. In conclusion, liver fibrosis markers, especially FIB-4 index, can be helpful for predicting SMML in CHC patients.

Abstract
BACKGROUND We aimed to elucidate the relationship between serum myostatin levels and other markers including skeletal muscle mass and to investigate the influence of serum myostatin levels on survival for patients with liver cirrhosis (LC). METHODS A total of 198 LC subjects were analysed in this study. Myostatin levels were measured using stored sera. We retrospectively investigated the relationship between myostatin level and other markers, and the influence of myostatin level on overall survival (OS). Assessment of skeletal muscle mass was performed using the psoas muscle index (PMI) on computed tomography images at baseline. PMI indicates the sum of bilateral psoas muscle mass calculated by hand tracing at the lumber three level on computed tomography images divided by height squared (cm2 /m2 ). The study cohort was divided into two groups based on the median myostatin value in each gender. RESULTS Our study cohort included 108 male and 90 female patients with a median age of 67.5 years. The median (range) myostatin level for male patients was 3419.6 pg/mL (578.4-12897.7 pg/mL), whereas that for female patients was 2662.4 pg/mL (710.4-8782.0 pg/mL) (P = 0.0024). Median (range) serum myostatin level for Child-Pugh A patients (n = 123) was 2726.0 pg/mL (578.4-12667.2 pg/mL), whereas that for Child-Pugh B or C patients (n = 75) was 3615.2 pg/mL (663.3-12897.7 pg/mL) (P = 0.0011). For the entire cohort, the 1-, 3-, 5-, and 7-year cumulative OS rates were 93.94%, 72.71%, 50.37%, and 38.47%, respectively, in the high-myostatin group and 96.97%, 83.27%, 73.60%, and 69.95%, respectively, in the low-myostatin group (P = 0.0001). After excluding hepatocellular carcinoma patients (at baseline) from our analysis (n = 158), the 1-, 3-, 5-, and 7-year cumulative OS rates were 96.0%, 77.93%, 52.97%, and 39.08%, respectively, in the high-myostatin group and 96.39%, 87.58%, 77.63%, and 73.24%, respectively, in the low-myostatin group (P = 0.0005). Higher age (P = 0.0111) and lower PMI (P < 0.0001) were identified as significant predictors of poorer OS in our multivariate analysis, while higher serum myostatin (P = 0.0855) tended to be a significant adverse predictor. In both genders, PMI, serum albumin, prothrombin time, and branched-chain amino acid to tyrosine ratio showed a significantly inverse correlation with myostatin levels, and serum ammonia levels showed a significantly positive correlation with myostatin levels. CONCLUSIONS Higher serum myostatin levels correlated with muscle mass loss, hyperammonemia, and impaired protein synthesis, as reflected by lower serum albumin levels and lower branched-chain amino acid to tyrosine ratio levels. High serum myostatin levels were also associated with a reduced OS rate in LC patients.

Effect of nalfurafine hydrochloride in patients with chronic liver disease with refractory pruritus on sleep disorders: a study protocol for single-arm, prospective, interventional study. BMJ Open Gastroenterol 2017; 4:e000177. [PMID: 29104757 PMCID: PMC5659178 DOI: 10.1136/bmjgast-2017-000177] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/26/2017] [Revised: 09/17/2017] [Accepted: 09/20/2017] [Indexed: 02/06/2023] Open
Abstract
Introduction Chronic liver disease (CLD)-related pruritus manifests as cholestasis symptoms, which can cause severe itches in the whole body and significantly decrease quality of daily activities and sleep. The actigram, which documents movement by means of an accelerometer, has been demonstrated to be useful for assessing sleep quality. Nalfurafine hydrochloride, which is a selective κ-opioid receptor agonist, exerts its antipruritic efficacies through a novel mechanism. We aimed to prospectively examine the effect of nalfurafine hydrochloride on sleep quality for patients with CLD with pruritus utilising actigram. Methods and analysis This study will be a single-centre, prospective, interventional, single-arm study. Our study participants are subjects whose pruritus was confirmed to be uncontrollable by antihistamines or antiallergics within 6 months before informed consent (IC). Evaluation time points using actigram will be (1) before administration of testing drug; (2) after 1 week; (3) after 4 weeks (primary endpoint); and (4) every 4 weeks thereafter. The follow-up period will be 6 months. We will prospectively assess and compare changes in sleep quality in patients with CLD with pruritus undergoing nalfurafine hydrochloride therapy using actigram. Quantitative variables will be compared by paired t-test. Ethics and dissemination This study has received approval from the Institutional Review Board at Hyogo College of Medicine (approval no 2325). The study protocol, IC form and other documents were reviewed and approved. Final data will be publicly disseminated regardless of the results. A report releasing study results will be submitted in an appropriate journal. Trial registration number UMIN000028161; Pre-results.

Development of a simple predictive model for decreased skeletal muscle mass in patients with compensated chronic liver disease. Hepatol Res 2017; 47:1223-1234. [PMID: 28019060 DOI: 10.1111/hepr.12857] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/21/2016] [Revised: 12/15/2016] [Accepted: 12/21/2016] [Indexed: 02/08/2023]
Abstract
AIM To develop and validate a simple predictive model using easily obtained clinical parameters to predict decreased skeletal muscle mass (DSMM) in chronic liver disease (CLD) patients (n = 652). METHODS Study subjects were divided into a training set (n = 326) and a validation set (n = 326). Decreased skeletal muscle mass was diagnosed based on skeletal muscle mass index measured by bioimpedance analysis. Variables significantly associated with DSMM were identified using univariate and multivariate analyses in the training set and used to construct a predictive formula. Receiver operating characteristic (ROC) curve analysis was carried out and the predictive model was validated in the validation set. Subgroup analyses were undertaken based on gender, age, or cirrhosis status of patients. RESULTS Body mass index (BMI), age, serum albumin, and branched-chain amino acid to tyrosine ratio (BTR) were determined to be significant predictive factors for DSMM. A composite formula "BALB score" was constructed [-7.740 + (0.539 × BMI) + (-0.112 × age) + (1.358 × albumin) + (-0.264 × BTR)]. The BALB score had the best predictive characteristics among all variables in both population sets (area under the ROC curve, 0.877-0.898). Patients with DSMM were stratified into three BALB score categories (>4, 0-4, and <0). Subgroup analyses also showed that BALB scoring was predictive of DSMM irrespective of gender, age, or cirrhosis status. The BALB score significantly correlated with psoas muscle index on computed tomography (rs = 0.6083 for men; rs = 0.6814 for women). CONCLUSION The BALB scoring system based on routinely used clinical parameters offers a convenient and non-invasive method for predicting DSMM in compensated CLD patients with high accuracy.
