Seropositivity and Titers of Anti-Smooth Muscle Actin Antibody Are Associated with Relapse of Type 1 Autoimmune Hepatitis.

BACKGROUND It is important to avoid relapse in autoimmune hepatitis (AIH) because repeated multiple relapses have been associated with a worse prognosis. However, risk factors for relapse before initiation of treatment are not fully understood. The aim of this study was to find predictive markers for relapse of type 1 AIH. MATERIAL AND METHODS We reviewed the records of 53 patients diagnosed with type 1 AIH based on the revised scoring system proposed by the International Autoimmune Hepatitis Group (IAIHG) between 2009 and 2014 at 4 hospitals belonging to the Saga Study Group of Liver Diseases (SASLD). We analyzed the differences in background characteristics between patients with or without relapse. RESULTS All patients achieved remission after treatment, and 9 (17%) subsequently relapsed. The relapsed patients were significantly younger and had a higher positive rate of anti-smooth muscle antibody (ASMA) than the non-relapsed patients (100% vs. 25%, P=0.0012). Moreover, relapse rate increased with titer of ASMA, while titer of antinuclear antibody was not associated with relapse rate. CONCLUSIONS ASMA is a useful predictive marker for relapse of type 1 AIH during or after withdrawal of medical therapy. More careful attention should be paid to immunosuppressive therapy in patients with high titers of ASMA.

Pilot study of liraglutide effects in non-alcoholic steatohepatitis and non-alcoholic fatty liver disease with glucose intolerance in Japanese patients (LEAN-J).

AIM: Non-alcoholic fatty liver disease (NAFLD), a hepatic manifestation of metabolic syndrome, is associated with an increased risk of developing lifestyle-related diseases including type 2 diabetes, cardiovascular disease and cerebral vessel disease. No current drug therapy provides the ideal effects of decreasing hepatic inflammation while simultaneously improving liver fibrosis. Liraglutide is a glucagon-like peptide-1 receptor agonist that affects the histological findings in patients with non-alcoholic steatohepatitis (NASH). This study was conducted to evaluate the effect and action of liraglutide for biopsy-proven NASH. METHODS: After lifestyle modification intervention for 24 weeks, subjects whose hemoglobin A1c levels failed to improve to less than 6.0% and/or whose alanine aminotransferase levels were not lower than baseline, received liraglutide at 0.9 mg/body per day for 24 weeks. RESULTS: Of 27 subjects, 26 completed the lifestyle modification intervention. Nineteen subjects received liraglutide therapy for 24 weeks. Body mass index, visceral fat accumulation, aminotransferases and glucose abnormalities improved significantly. Repeated liver biopsy was performed in 10 subjects who continued liraglutide therapy for 96 weeks. Six subjects showed decreased histological inflammation as determined by NASH activity score and stage determined by Brunt classification. We saw no significant adverse events during therapy with liraglutide. CONCLUSION: Our pilot study demonstrated that treatment with liraglutide had a good safety profile and significantly improved liver function and histological features in NASH patients with glucose intolerance.

Comparison of recurrent biliary obstruction with the use of metal and plastic stents in EUS-guided biliary drainage: A propensity score-matched analysis.

Background and Objectives: In transpapillary biliary drainage, metal stents (MSs) exhibit a lower incidence of a biliary obstruction than plastic stents (PSs). However, few studies have compared recurrent biliary obstruction (RBO) when MSs and PSs are used in EUS-guided hepaticogastrostomy (EUS-HGS) and choledochoduodenostomy (EUS-CDS). We retrospectively evaluated the RBO for both stents in each procedure. Patients and Methods: : Between November 2012 and December 2020, 85 and 53 patients who underwent EUS-HGS and EUS-CDS for unresectable malignant biliary obstruction, respectively, were enrolled. Factors associated with RBO were assessed. Clinical outcomes were compared between the MS and PS groups using propensity score matching. Results: : The clinical success rate and procedure-related adverse events were similar in the MS and PS groups. Multivariate analysis identified the use of PS as a factor associated with RBO (EUS-HGS, P = 0.03; EUS-CDS, P = 0.02). After matching, the median time to RBO in EUS-HGS (MS: 313; PS: 125 days; P = 0.01) in the MS group was longer than that in the PS group. The cumulative incidence of RBO at 1, 3, and 6 months in the MS group was significantly lower than that in the PS group for EUS-HGS (MS: 4.0%, 8.2%, and 8.2%; PS: 12.4%, 24.9%, and 39.5%, respectively, P = 0.01). Conclusions: : MS exhibited a lower rate of RBO than PS for EUS-HGS and EUS-CDS.

Decrease in fasting insulin secretory function correlates with significant liver fibrosis in Japanese non-alcoholic fatty liver disease patients.

BACKGROUND AND AIM: Non-alcoholic fatty liver disease (NAFLD) is typically associated with metabolic syndrome and diabetes, and insulin resistance is involved in its pathogenesis. However, the relationship between insulin secretion and NAFLD is unclear. We aimed to characterize the relationship between fasting insulin secretory function (ISF), evaluated using the homeostatic model assessment-beta cell function (HOMA-ß) and the severity of fibrosis during NAFLD. METHODS: A-ß was calculated in 188 patients with biopsy-confirmed NAFLD, and the correlations between Log HOMA-ß and clinical parameters, including hepatic fibrosis, were calculated. RESULTS: Log HOMA-ß was significantly lower in NAFLD patients with significant fibrosis (stages 2-4) than in those in the early stages (stages 0-1) (median [interquartile range]) (2.1 [1.9-2.4] vs 2.0 [1.8-2.2], P = 0.04). The prevalence of significant fibrosis decreased with increasing Log HOMA-ß: it was 59.2% in participants with low ISF (Log HOMA-ß < 1.85), 43.6% in those with intermediate ISF (1.85 ≤ Log HOMA-ß < 2.25), and 68.0% in those with high ISF (Log HOMA-ß ≥ 2.25). Patients with lower Log HOMA-ß had lower current body mass index (BMI), BMI at 20 years of age, and peak lifetime BMI than patients with intermediate or high Log HOMA-ß. CONCLUSIONS: Fasting ISF decreased alongside the development of liver fibrosis in NAFLD, suggesting that an impaired ß cell function has a characteristic finding of significant liver fibrosis in relatively nonobese Japanese patients.

Chronic Hepatitis C Treatment with Daclatasvir Plus Asunaprevir Does Not Lead to a Decreased Quality of Life.

Objective The aim of this study was to determine if direct-acting antiviral (DAA) treatment with daclatasvir (DCV) plus asunaprevir (ASV) for 24 weeks influenced the health-related quality of life (HRQOL) at 12 and 24 weeks after treatment initiation [end of treatment (EOT)]. Methods This was a prospective, longitudinal study comparing the HRQOL of patients receiving DAA treatment at 12 weeks after treatment initiation and EOT with the HRQOL at baseline. We used a Japanese-validated version of the 8-item Short Form Health Survey (SF-8) to assess the HRQOL of patients. This score can be compared to the Japanese normative sample scores of SF-8. Wilcoxon signed-rank tests were used to compare the HRQOL before treatment, 12 weeks after treatment initiation, and at EOT. Patients We enrolled patients who received 24-week combination therapy using DCV and ASV for HCV at Saga University Hospital between November 2014 and July 2015. Those who discontinued treatment due to relapse or adverse reactions during the treatment period were excluded from the study. Results There were no significant changes in any of the SF-8 subscales, Physical component scores (PCS) or mental component scores (MCS) during the treatment period for both males and females. Conclusion Our study makes a significant contribution to the literature because 24-week DAA treatment with DCV plus ASV did not decrease the HRQOL at 12 or 24 weeks after treatment initiation.
