Abstract
Background and Aim Hepatitis C virus (HCV) infection causes insulin resistance and diabetes as extrahepatic manifestations. We aimed to analyze the effect of HCV eradication by direct‐acting antiviral (DAA) agents on glucose tolerance. Methods The hemoglobin A1c (HbA1c) of 272 patients with HCV infection who achieved a sustained virologic response (SVR) was analyzed at baseline before DAA treatment, at the end of DAA therapy (ETR), and 12 weeks after therapy (Post12W). Results There were no significant differences in HbA1c between baseline, ETR, and Post12W in the overall patients. When the data were stratified according to the presence or absence of diabetes, median HbA1c significantly decreased from baseline (7.2%) to ETR (6.8%) and Post12W (6.8%) in the 55 patients with diabetes, whereas there were no significant changes in the patients without diabetes. Basal HbA1c, fasting plasma glucose, and age were independently associated with the changes in HbA1c according to multivariate analysis, and the predictive formula for changes in HbA1c was found to be ΔHbA1c (%) = 1.449–0.4* HbA1c (%) + 0.012 × Age (year). There were no changes in body mass in diabetic or nondiabetic patients. In diabetic patients taking medication, 63.4% of patients needed less medication. Conclusions Eradication of HCV improves glycemic control, indicated by a 0.4% decrease in HbA1c in diabetes.

Development and course of diabetes according to genetic factors and diabetes treatment among patients with nonalcoholic fatty liver disease. Nutrition 2020; 83:111080. [PMID: 33348109 DOI: 10.1016/j.nut.2020.111080] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2020] [Revised: 11/06/2020] [Accepted: 11/06/2020] [Indexed: 12/12/2022]
Abstract
OBJECTIVES Many patients with nonalcoholic fatty liver disease (NAFLD) also have diabetes. However, the genetic factors associated with diabetes in NAFLD are unclear. In this study, we investigated the clinical course and risk factors of diabetes development. METHODS A total of 544 patients (275 men; 50.6%) with a median age of 53 y and biopsy-confirmed NAFLD enrolled in the study. Patatin-like phospholipase 3 and voltage-gated potassium channel KQT-like subfamily member 1 (KCNQ1) single nucleotide polymorphisms were identified in 287 cases. There were 272 patients without diabetes, and 64, 141, and 67 patients with diabetes not treated with an oral hypoglycemic agent, treated with an oral hypoglycemic agent, and treated with insulin, respectively. Changes in biochemical parameters and body weight over a 1-y period were determined in patients treated with incretin agents (n = 91), a sodium glucose cotransporter 2 inhibitor (n = 19), or both (n = 33). The prevalence and risk factors for diabetes development among patients with NAFLD were determined in nondiabetic patients. RESULTS Among patients with NAFLD, half of the patients had diabetes and the incidence was high in those with advanced fibrosis. Reduction in body weight was higher after sodium glucose cotransporter 2 inhibitor treatment (P = .050) and in KCNQ1 CC genotype patients (P < .05). Reduction in hemoglobin A1c level was significantly lower in patatin-like phospholipase 3 GG subjects (P < .05). De novo diabetes developed in 44 patients (10-y incidence: 17.9%), especially in obese (P = .046) and KCNQ1 CC genotype patients (P < .01). CONCLUSIONS Patient genetic background affected treatment response and incidence of diabetes in patients with NAFLD.

Abstract
A 70-year-old female was found to have multiple hepatic cysts at her annual checkup. In the posterior segment of the right lobe of the liver, an 81 × 67 mm circular cystic lesion was detected by contrast-enhanced computed tomography (CT). Magnetic resonance imaging (MRI) of the cyst revealed a solid component. The cyst had a capsule-like structure and non-uniform fluid accumulation suggested bleeding. Since the lesion was enlarged and malignancy could not be ruled out, it was surgically resected. Histopathologically, reticular fibers of the liver were seen in necrotic tissue and the lesion was diagnosed as a bleeding hepatocellular carcinoma (HCC). The non-cancerous liver tissue showed non-cirrhotic steatohepatitis. This was an unusual presentation of HCC.

Abstract
BACKGROUND AND AIM The incidence of mortality and hepatocellular carcinoma (HCC) in patients with non-alcoholic fatty liver disease (NAFLD) has been reported, but the long-term outcomes of Japanese patients with NAFLD are not fully evaluated. METHODS We enrolled 365 Japanese patients with biopsy-confirmed NAFLD (1990-2008) followed for ≥ 6 months: 185 males (50.7%); median age (54 years); advanced fibrosis 108 (29.8%); HCC, n = 26 (7.1%); diabetes, n = 191 (52.3%); dyslipidemia, n = 234 (64.1%); and hypertension, n = 193 (52.9%). We analyzed the survival and new-onset HCC rates for hepatic fibrosis as well as complications and the treatment of lifestyle-related diseases. RESULTS During the median 7.1-year follow-up, 44 patients (12.1%) died: n = 28 liver-related (10 years liver-related death, 9.4%) and n = 16 non-liver-related deaths (10 years non-liver-related death, 4.9%). Both incidence rates were significantly higher in the advanced fibrosis group. The incidence of HCC at 10 years was 20.1% in the advanced fibrosis group, and the mortality was increased in patients with higher age, history of HCC, lower seru\m level of albumin, higher level of γ-glutamyltransferase, and insulin treatment for diabetes. Risk factors for HCC onset were higher levels of aspartate aminotransferase and triglyceride and hypertension treatment. Platelet count < 11.5 × 104 /μL was revealed as a risk factor for death and HCC development. CONCLUSIONS The rates of both liver-related and non-liver-related deaths and HCC development were significantly prominent in the patients with advanced fibrosis. It is important to identify and treat NAFLD patients who have several risk factors and advanced fibrosis, which might be predicable simply by the platelet count.

Abstract
AIM Hepatocellular carcinoma (HCC) can arise from Fontan-associated liver disease (FALD); this is known as FALD-HCC. The clinical features of FALD-HCC are unclear. Thus, we examined the incidence and clinical characteristics of FALD-HCC. METHODS From 1972 to 2019, 122 patients developed liver disease after undergoing Fontan procedures. HCC was diagnosed in 12 (9.8%) FALD patients. We compared FALD-HCC and non-HCC patients. RESULTS The incidence of HCC was 0.8% and 2.9% in FALD 10 and 20 years after the Fontan procedure, respectively. The median age of patients at diagnosis of HCC was 32.5 years (range 20.6-46.1 years), and seven of the 12 patients were men. Patients with FALD-HCC had a higher incidence of liver cirrhosis and polysplenia than non-HCC patients. Liver tumors were detected as single nodules in eight patients, and the median diameter was 47 mm (range 11-105 mm). HCC was treated by surgical resection in two patients, transcatheter arterial chemoembolization or chemotherapy in three patients, and proton beam therapy in four patients. Three patients could not be treated because of their poor condition. Four patients died of liver/cardiac failure and HCC, and HCC was controlled in three patients. The survival rate after 25 years was significantly lower in patients with FALD-HCC than non-HCC patients (68.6% vs. 97.9%, respectively; P < 0.01). CONCLUSIONS Of the 122 patients with FALD, 12 developed HCC 20 years after surgery. Because complications of HCC are associated with poor prognosis, constant surveillance for HCC should begin 10 years after surgery.

Abstract
BACKGROUND AND AIM We evaluated the characteristics of hepatocellular carcinoma (HCC) in patients who had non-alcoholic fatty liver disease (NAFLD) without cirrhosis. METHODS We prospectively followed NAFLD patients at our University hospital. NAFLD was diagnosed from detection of steatosis by histology or imaging, no alcohol intake, and exclusion of other liver diseases. Cirrhosis was defined by histological features, imaging data, and symptoms. We compared NAFLD-related HCC with or without cirrhosis and non-cirrhotic NAFLD with or without HCC. RESULTS There were 48 non-cirrhotic HCC patients and 71 cirrhotic HCC patients. Multiple logistic regression analysis revealed that other than liver function factors, male gender (OR: 5.603, 95%CI: 1.577-19.900), light drinker (OR: 2.797, 95%CI: 1.031-7.589), and tumor size (OR: 1.031, 95%CI 1.009-1.055) differ significantly between these two groups. The recurrence rate was significantly lower in the non-cirrhotic HCC group than the cirrhotic HCC group, with risk factors being des-γ-carboxy prothrombin and the number of HCCs. The non-cirrhotic HCC group showed significantly better survival because of absence of non-cancerous liver failure. Comparison between non-cirrhotic NAFLD patients with or without HCC (n = 612) revealed the following risk factors for HCC: male gender (OR: 7.774, 95%CI: 2.176-27.775), light drinker (OR: 4.893, 95%CI: 1.923-12.449), and high FIB4 index (OR 2.634, 95%CI: 1.787-3.884). CONCLUSION In patients with non-cirrhotic NAFLD, important risk factors for HCC were male gender, alcohol consumption, and the FIB4 index. HCC recurrence and survival were only influenced by the tumor stage. We should be aware of alcohol consumption as a modifiable risk factor for HCC.

Abstract
We examined a 22-year-old woman who was admitted to our hospital with abdominal distention. At 19 years of age, the patient presented with hepatosplenomegaly. She was examined several times in another hospital; however, the cause was unidentified. Our evaluation showed severe pancytopenia and a spleen 13×24 cm in size. The serum levels of angiotensin-converting enzyme and lysozyme were elevated. She was diagnosed with liver sarcoidosis based on non-caseating epithelioid granuloma in liver biopsy tissue. To improve the symptoms, splenectomy was performed, and her pancytopenia and symptoms improved. Sarcoidosis should be considered in cases of massive splenomegaly.

Abstract
We treated the case of a 22-year-old male patient with liver dysfunction. At 1 year of age, hepatic fibrosis was suspected. In addition, due to the presence of retinitis pigmentosa, renal failure, obesity, mental retardation, and hypogonadism, he was diagnosed with Bardet-Biedl syndrome (BBS). Skipping of exons 14 and 17 in the sodium channel and clathrin linker 1 (SCLT1) gene was observed. At 22 years of age, the liver enzyme levels were further elevated and a diagnosis of microvesicular steatohepatitis was made. Insulin resistance, a reduction of muscle mass, an impairment of the fatty acid metabolism, and hyperleptinemia in this syndrome may cause steatohepatitis.

Abstract
BACKGROUND AND AIM The incidence of acute hepatitis A [AH (A)] is decreasing because of improvements in hygiene; however, cases of sporadic severe hepatitis are still being reported. We assessed the epidemiology of AH (A) in Japan. METHODS This was a hospital-based retrospective study, in which 126 AH (A) patients (96 men [76%], median age 39 [range, 19-66] years) were enrolled. Patients diagnosed with AH (A) before 2001 (n = 79) and after 2001 (n = 47) were compared. RESULTS The incidence of AH (A) showed peaks in 1990, 1999, and 2018. After 2001, one patient had hepatitis B virus, four had human immunodeficiency virus, and three had syphilis coinfections. Before and after 2001, HAV was transmitted, respectively, by raw oysters (28% and 26%), overseas travel (19% and 28%), and sexual contact (0% and 19%) (P < 0.01). The frequencies of symptoms were appetite loss (51% and 32%), fever (63% and 81%), and diarrhea (3% and 13%) (all P < 0.05), respectively. On admission, the median levels of alanine aminotransferase (1455 and 3069 U/L) and γ-glutamyl transpeptidase (221 and 345 U/L) were significantly higher (P < 0.01), and the prothrombin time (77.5% and 65.9%) and platelet count (22.7 and 16.4 × 10/μL) were significantly lower after 2001 (P < 0.05). A time to normalization of the bilirubin level ≥ 30 days was associated with older age and a diagnosis of AH (A) after 2001. CONCLUSIONS Outbreaks and severe AH (A) cases due to sexual transmission have been reported recently. It is necessary to examine their sexual behavior and other sexual infection.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is the most common preventable chronic liver disorder in developed countries, the prevalence of which is increasing worldwide due to its association with obesity and type 2 diabetes. However, the exact mechanisms of NAFLD pathophysiology remain poorly understood including its progression to the more severe nonalcoholic steatohepatitis (NASH). New advances for early detection and monitoring of NASH progression are limited due to the lack of specific blood biomarkers, thus requiring invasive liver biopsies for histopathology. Herein, multisegment injection-capillary electrophoresis-tandem mass spectrometry (MSI-CE-MS/MS) is validated as a high throughput, robust, and quantitative platform for targeted analysis of a panel of 16 serum γ-glutamyl dipeptides from a cohort of NASH adult patients from Japan (median age = 53 years, median BMI = 27 kg/m2, n = 116). Multiplexed separations based on MSI-CE-MS/MS enable the design of unique data workflows that rely on customizable serial sample injection formats for accurate determination of γ-glutamyl dipeptides with quality control. Also, the introduction of a liquid coolant device to the capillary outlet improves long-term migration time stability in CE. Unsupervised pattern recognition methods revealed two distinctive NASH subgroups based on their contrasting γ-glutamyl dipeptide status despite patients having similar clinical phenotypes and NASH activity scores (median NAS ≈ 6.0). There was an inverse correlation between serum γ-glutamyl dipeptide concentrations and γ-glutamyltransferease (GGT) enzyme activity (r = -0.46; p = 2.5 × 10-7), which was indicative of a low-risk (n = 64) as compared to a high-risk (n = 52) patient subgroup with impaired glutathione salvage pathway and likely poor clinical prognosis. Our findings highlight the key role of defects in the γ-glutamyl cycle for differentiation of NASH patients, which may enable better risk assessment of long-term survivorship as a complement to standard liver enzyme screens and histopathology.

Abstract
BACKGROUND AND AIM To elucidate features of nonobese non-alcoholic fatty liver disease (NAFLD), we assessed Japanese patients with NAFLD stratified by body mass index (BMI) and by sex. METHODS Biopsy-proven 762 NAFLD patients (404 men) were classified into three groups by the Japanese criteria: nonobese group (BMI < 25 kg/m2 ), obese group (25 to 30), and severely obese group (≥ 30). Clinicopathological features and single nucleotide polymorphism of patatin-like phospholipase 3 (PNPLA3) rs738409 were investigated, and body composition analysis was performed by bioelectrical impedance analysis and computed tomography. RESULTS Over 25% of men and almost 40% of women were nonobese, but most of them had visceral fat obesity and/or insulin resistance. The median age (years) of the nonobese, obese, and severely obese men was 49.9, 46.8, and 40.5 (P < 0.01), respectively, while those of women was 60.2, 59.6, and 48.5 (P < 0.01), respectively. The prevalence of metabolic comorbidities and PNPLA3 risk alleles did not differ among these groups in both sexes. Also, the prevalence of non-alcoholic steatohepatitis was not significantly different in both sexes, although nonobese patients had a higher prevalence of mild steatosis. Advanced fibrosis showed a marked difference between men and women. Advanced fibrosis was significantly more frequent among severely obese men (nonobese: 31.0%, obese: 41.6%, severely obese: 60.9%; P < 0.01), but it was lower among severely obese women (51.4%, 62.9%, 33.7%; P < 0.01). Skeletal muscle mass was significantly lower in nonobese patients. CONCLUSIONS Non-alcoholic fatty liver disease was not milder in nonobese patients. Histological steatosis was associated with BMI, but advanced fibrosis was not and showed a significant sex difference.

Abstract
Background The vasopressin V2-receptor antagonist tolvaptan is used to treat cirrhotic patients with ascites. We investigated the outcome of long-term treatment. Methods This was a single-center retrospective study. Overall, 170 cirrhotic patients (95 males, median age 63 years) were enrolled and received tolvaptan orally after hospitalization for ascites, which included treatment with conventional diuretics. We compared patients who withdrew tolvaptan treatment after < 1 year (n = 90) with patients who continued treatment for ≥1 year (n = 37). In continuously treated patients, the pretreatment and post-treatment (1 year) blood biochemistry values were assessed. Results Overall, 37 patients received treatment for ≥1 year and showed a higher response after tolvaptan therapy. The reduction in body weight was 2.0 (− 3.4–17.2) kg compared to discontinued cases, which had a body weight reduction of 1.1 (− 6.2–7.5) kg after 1 week. The group that received treatment for ≥1 year had a significantly lower rate of the complication gastroesophageal varices and also showed better liver function. In patients with continued treatment, serum levels of albumin was significantly higher without renal disturbance after 1 year of treatment. The prothrombin time/international normalized ratio and ammonia level were also significantly improved. Multivariate analyses showed that a change in body weight reduction and serum levels of albumin were predictive factors of continued administration. Conclusions Long-term tolvaptan treatment increased serum levels of albumin, decreased ammonia levels, and preserved renal function after 1 year of treatment. A reduction in body weight after 1 week was associated with a favorable outcome of tolvaptan therapy.

Abstract
Background and Aim Given the use of direct‐acting antivirals (DAAs) to treat hepatitis C virus (HCV), their effects on hepatocarcinogenesis should be determined. Methods This study enrolled 349 patients with HCV who underwent DAA treatment at our hospital between 2014 and 2018. Their median age was 65 years, and 184 were male; 301 cases were of HCV serotype 1, and 48 were of serotype 2. The DAA treatment was daclatasvir/asunaprevir in 107 cases, sofosbuvir (SOF)/ledipasvir in 147 cases, ritonavir‐boosted ombitasvir/paritaprevir in 28 cases, elbasvir/grazoprevir in 19 cases, and SOF/ribavirin in 48 cases. The patients’ histories included hepatocellular carcinoma (HCC) in 45 cases, liver transplant (LT) in 10 cases, and kidney transplant (KT) in 17 cases. Results Sustained virological responses occurred in 335 cases (96%). DAA treatment was initiated a median of 16.3 months after HCC treatment. After DAA treatment, 15 cases (33%) had recurrence of HCC after a median of 11.6 months, and 3 cases (1%) developed de novo HCC. Six LT patients and one KT patient had HCC; however, no HCC was observed after DAA. The incidence of HCC was significantly higher in patients with multiple HCC treatments in the Cox hazard model (hazard ratio 1.664, 95% confidence interval 1.134–2.441, P < 0.01). Surgical resection or LT reduced the risk of HCC. Conclusions DAA did not increase the rate of HCC, even in immunosuppressed patients. However, careful follow‐up for HCC recurrence is required in previously treated cases.

Abstract
Background and Aim Alcoholic liver disease (ALD) and non‐alcoholic fatty liver disease (NAFLD) have common hepatic histological features, but few studies have compared the genomic backgrounds of these two diseases. Here, we compared the genetic differences between ALD and NAFLD. Methods This study enrolled 318 Japanese patients with ALD (n = 118; male, 86%; median age, 62 years; liver cirrhosis, 58%; hepatocellular carcinoma [HCC], 31%) and NAFLD (n = 200; male, 55%; age, 61 years; cirrhosis, 19%; HCC, 12%). The genotype frequencies of 10 single nucleotide polymorphisms (SNPs) were analyzed. Results The ADH1B genotype GG and ALDH2 genotype GG were observed more frequently, and the percentage of patients with the MTP genotype GG was lower in ALD compared with NAFLD patients (ADH1B, 16 vs 4%; ALDH2 84 vs 44%; MTP 62 vs 72%, respectively; all P < 0.01). Comparing noncirrhosis to cirrhosis, the frequency of the potassium voltage‐gated channel subfamily Q member 1 (KCNQ1) genotype TT and adrenoceptor beta 3 (ADRB3) genotype TT was increased significantly in ALD‐related cirrhosis. In contrast, the patatin‐like phospholipase 3 (PNPLA3) genotype CC was decreased significantly in NAFLD‐related cirrhosis. A comparison of patients with and without HCC demonstrated that the KCNQ1 genotype TT was increased significantly in both HCC groups. In addition, associations between the KCNJ15 genotype GG and ALD‐HCC and the G allele of PNPLA3 and NAFLD‐HCC were identified. Conclusions SNPs in genes related to ethanol and lipid metabolism clearly differed between patients with ALD and NAFLD. KCNQ1 might affect the progression and hepatocarcinogenesis in both ALD and NAFLD.

Abstract
Here, we describe a 42-year-old male patient with late-onset hepatic failure (LOHF) due to acute-onset autoimmune hepatitis. At first, his response to steroid therapy was good, but hepatitis relapsed during steroid pulse therapy. Deterioration of liver function caused LOHF, and LOHF has a poor prognosis, particularly when it is complicated by infection. Systemic infection by Staphylococcus aureus resulted in a skin rash and septic pulmonary embolism, and is an absolute contraindication for liver transplantation (LT). In this treatment network, hepatologists and a transplant surgeon cooperated to overcome severe infection and their efforts led to successful transplantation. On-line hemodiafiltration is an indispensable treatment option for acute liver failure. Infection control is crucial for LT and an intensive medical care network led to successful living-donor LT.

Abstract
Liver transplantation (LT) has been carried out for acute liver failure, end-stage liver disease, and congenital metabolic disease in more than 7000 cases in Japan. Liver transplantation has been established as a treatment option, and survival rates have improved. In 2016, a new registration/allocation policy and a new scoring system for deceased donor LT were established. The management of perioperative patients and preoperative therapy for liver failure, nutrition, and preventing infection were upgraded. Moreover, methods for preventing disease recurrence, and treating hepatitis C and B have been developed and are particularly crucial for good outcomes in LT. Treatment of the complications of obesity, lifestyle-related diseases, and malignancy is also required post-LT. Managing patients after LT contributes to better survival and quality of life. The role of hepatologists is becoming broader and more important.

Abstract
Objective Hyponatremia is frequently observed in patients with decompensated liver cirrhosis and it is also related to a poor prognosis. The vasopressin V2-receptor antagonist tolvaptan is used to treat cirrhotic patients with ascites and increases the serum sodium (Na) level. In this study, we investigated (i) whether or not correction of the Na level improves the prognosis of cirrhotic patients with ascites and (ii) predictors of normalization of the serum Na level after tolvaptan therapy. Methods This was a single-center retrospective study. A total of 95 Japanese cirrhotic patients (60 men, median age 63 years) were enrolled and received tolvaptan orally after hospitalization for ascites treatment. The serum Na level was monitored during the period of tolvaptan treatment. The laboratory data and survival rates of patients who achieved serum Na levels of <135 and ≥135 mEq/L after 1 week were compared. Results Patients showed serum Na levels of 136 (121-145) mEq/L, and 42.1% had a serum Na level of <135 mEq/L. Among patients with an initial serum Na level <135 mEq/L, 60.0% achieved a normal level after 1 week, and the survival rate was significantly higher in patients with a normalized serum Na level (p<0.01). The pretreatment brain natriuretic peptide (BNP) level was predictive of achieving a serum Na level of ≥135 mEq/L (odds ratio: 0.87, 95% confidence interval: 0.316-0.987, p<0.05). Conclusion Normalization of the Na level after one week was associated with a favorable outcome of tolvaptan therapy, and Na correction improved the prognosis.

Abstract
AIM The vasopressin V2 receptor antagonist tolvaptan has been used for the treatment of cirrhotic patients with ascites; however, no predictor of efficacy and prognosis has been developed. We evaluated candidate predictors of response to tolvaptan treatment. METHODS This was a single-center retrospective study. Overall, 97 Japanese cirrhotic patients (60 men, median age 63 years), who were hospitalized for ascites treatment including oral tolvaptan coupled with conventional diuretics, were enrolled. The efficacy of tolvaptan was defined as a urination increase of ≥500 mL or a urine volume ≥2000 mL/day on the day following treatment. The prognosis of tolvaptan treatment was evaluated by the post-treatment survival time by Kaplan-Meier analysis. RESULTS Tolvaptan therapy was effective in 67% of cirrhotic patients. Patients showed -1.5 (-17.2 to +6.2) kg change in body weight and 40% achieved ≥2.0 kg reduction in body weight after 1 week of treatment. Platelet counts, urine sodium (Na) level, and urine Na/potassium (Na/K) ratio were higher, and the blood urea nitrogen (BUN)/creatinine (Cr) ratio was lower, in cases showing a response to tolvaptan. The combination of a BUN/Cr ratio ≥17.5 and urine Na/K ratio <3.09 was predictive of being non-responsive to tolvaptan, and the response rate in these patients was only 39% (P < 0.01). The mean post-treatment survival duration was significantly longer in patients who responded to tolvaptan therapy. CONCLUSIONS Urinary BUN and Na excretion were predictive of a response to tolvaptan, and tolvaptan treatment may improve the prognosis of cirrhotic patients.

Abstract
Primary biliary cholangitis (PBC) is diagnosed mainly in female individuals, and risk factors for PBC recurrence (rPBC) after liver transplantation (LT) from cadaveric donors have been reported. We conducted a retrospective multicenter study of rPBC in female patients after living‐donor LT (LDLT). A total of 388 female patients undergoing LDLT for end‐stage PBC were enrolled, and the effects of preoperative and operative factors were evaluated. Postoperative factors were evaluated in 312 patients who survived for more than 1 year post‐LDLT. rPBC was defined as abnormal hepatic enzyme levels with typical histological findings in liver biopsies. Fifty‐eight patients (14.9%) developed rPBC with a median of 4.6 (0.8‐14.5) years post‐LT. Cox hazard analysis (P < 0.05) showed that younger recipient age (hazard ratio, 0.95; 95% confidence interval, 0.920‐0.982), shorter operative time (1.00; 0.995‐0.999), higher serum immunoglobulin M level (1.00; 1.001‐1.002), donor sex mismatch (2.45; 1.268‐4.736), human leukocyte antigen B60 (2.56; 1.336‐4.921) and DR8 (1.98; 1.134‐3.448), and initial treatment with cyclosporine A (3.14; 1.602‐6.138) were significantly associated with rPBC. The frequencies of Child‐Turcotte‐Pugh class C (0.46; 0.274‐0.775), the model of end‐stage liver disease score (0.96; 0.914‐0.998), and updated Mayo risk score (1.02; 1.005‐1.033) were significantly lower in rPBC. Posttransplantation use of steroids decreased and that of antimetabolites increased the frequency of rPBC. Conclusion: The timing of LT, recipient conditions, donor characteristics, and immunosuppressive medications may be associated with rPBC in LT recipients. (Hepatology Communications 2017;1:394–405)

Abstract
Poorly controlled diabetes mellitus (DM) patients sometimes show serum transaminase elevations due to steatohepatitis. However, we experienced four cases with type 1 DM with sharp elevations in serum transaminases that could not be explained by steatohepatitis alone and showed bright liver. They were diagnosed with glycogenic hepatopathy (GH) clinicopathologically. The four patients had a median age of 22.5 years (range, 19-29 years) and 12.5 (4-15)-year histories of type 1 DM and showed marked increases in serum transaminases (aspartate aminotransferase, 698 U/L [469-2763 U/L]; alanine transaminase, 255 U/L [216-956 U/L]). Diabetes mellitus control was poor and hemoglobin A1c was 12.7% (11-16.5%). Three cases had a past history of diabetic ketoacidosis. Hepatomegaly and hyperdense liver were seen on computed tomography scans. Magnetic resonance imaging showed low intensity in T2-weighted images. The pathological findings revealed pale and swollen hepatocytes and glycogenated nuclei. The architecture of the liver was preserved, and steatosis and fibrosis were mild. The cytoplasm of hepatocytes stained densely positive with periodic acid-Schiff, and the positive staining disappeared after diastase digestion, suggesting glycogen deposition. No other cause of hepatitis was evident, and the diagnosis was GH. Elevated transaminases improved within 1 month with good glycemic control. Transaminase elevations were observed several times in three cases with poor glycemic control. Glycogenic hepatopathy is rare, but extremely high serum elevations of transaminases are important to identify clinically. Despite showing a good clinical course in general, GH sometimes recurs and requires strict glycemic control. Clinicians should be aware of and recognize GH when dealing with uncontrolled DM patients.

Abstract
Objective Growth hormone (GH) deficiency has recently been reported as a cause of nonalcoholic fatty liver disease (NAFLD), and GH supplementation has been shown to improve the histology of NAFLD. The aim of the present study was to clarify the relationship between the histological severity of NAFLD and production of the GH/insulin-like growth factor 1 (IGF-1) axis. Methods A total of 222 Japanese patients with liver biopsy-confirmed NAFLD and 55 patients with hepatitis C virus (HCV)-related chronic liver disease (CLD) were enrolled in the present study. The serum levels of GH, IGF-1, and IGF-binding protein 3 (IGFBP-3) were measured and their relationships with the histological severity of liver disease were assessed. To exclude age- and sex-related differences, the IGF-1 standard deviation score (IGF-1:SDS) was determined for each patient. Results With respect to the stage of fibrosis in patients with NAFLD, the serum GH levels were higher and the serum IGFBP-3 levels and IGF-1:SDSs were lower in patients with cirrhosis (grade F4 fibrosis) than in patients grade F1-F3 fibrosis; moreover, these differences were statistically significant (all p<0.01). The GH, IGF-1, and IGFBP-3 levels were not correlated with fibrosis in patients with HCV-related CLD. Furthermore, the GH levels were lower and the IGFBP-3 levels were significantly higher in patients with severe steatosis (S3) than in patients with mild to moderate steatosis (S1-S2) (p<0.05). Conclusion Increased GH levels and decreased IGF-1 and IGFBP-3 levels might contribute to the progression of NAFLD. The GH/IGF-1 axis may be important in the development of NAFLD, but not in patients with HCV-related CLD.

Abstract
BACKGROUND In Japan, the prevalence of hepatocellular carcinoma (HCC) associated with nonviral liver disease, especially with nonalcoholic fatty liver disease (NAFLD-HCC) and alcoholic liver disease (ALD-HCC), has been increasing. Clarification of the clinical features of NAFLD-HCC and ALD-HCC is needed. We performed a large retrospective multicenter survey to clarify the clinical course of these two types of HCC. METHODS Clinical characteristics, survival, and recurrence were examined in 532 patients with ALD-HCC and 209 patients with NAFLD-HCC who were diagnosed between January 2000 and December 2013. RESULTS The ALD-HCC patients were predominantly male and were younger than the patients with NAFLD-HCC. Lifestyle-related diseases were significantly more common in the NAFLD-HCC group, but the prevalence of cirrhosis was significantly higher in the ALD-HCC group. The histological diagnosis of NAFLD-HCC showed a gender difference (F4; 72.7 % in the females vs. 37.6 % in the males). The characteristic features of HCC including histology, survival rate, and recurrence rate were quite similar in the NAFLD-HCC and ALD-HCC groups: 5-year survival rates 49.1 vs. 43.7 %; 5-year recurrence rates 69.6 vs. 65.4 %, respectively. However, the risk factors for recurrence differed between the two groups: des-gamma-carboxy prothrombin was a risk factor in NAFLD-HCC and α-fetoprotein was a risk factor in ALD-HCC. CONCLUSIONS Although the characteristic features underlying these two diseases are different, the two HCC groups showed a similar clinical course. The recurrence rates of the two HCC groups were relatively high. We found that critical tumor markers for recurrence differed between the two diseases.

Abstract
AIM Recently, the short-term efficacy of the vasopressin V2 receptor antagonist tolvaptan for the treatment of ascites in cirrhosis was reported. However, the long-term effects remain unknown. Here, we report the clinical features of decompensated cirrhosis treated using long-term tolvaptan therapy, and evaluate its safety and efficacy. METHODS Fifty-five cirrhotic patients hospitalized due to ascites, despite receiving appropriate diuretic treatment, were treated with tolvaptan. We excluded 35 patients due to liver transplant (20.0%), death (28.6%), poor general status (14.3%), improved ascites (5.7%) or other reasons (31.4%). In 20 cases treated with tolvaptan for 6 months, total body water (TBW) and extracellular fluids (ECW) were measured using bioelectric impedance analysis (BIA) with an InBody720. RESULTS The median age of the 20 patients was 64 years (range, 48-90), and 60% were male. The etiology of cirrhosis included hepatitis C (45%), alcohol-induced (20%) and other (35%). The percentage of patients with Child-Pugh class A, B and C was 0%, 40% and 60%, respectively. Biochemical findings revealed that serum creatinine levels and estimated glomerular filtration rate were not affected during 6 months of treatment with tolvaptan, and there was no renal disturbance. The median serum sodium levels were increased from 138 to 139 mEq/L, but serious adverse events related to renal and liver function were not observed. Data also revealed that long-term treatment reduced the BIA-estimated ECW/TBW ratio. CONCLUSION Long-term tolvaptan treatment was a safe and effective treatment for decompensated cirrhosis.
