In 2004, we implemented a referral system for patients with acute liver injury (ALI) based on an established formula that estimates the risk of progression to acute live failure (ALF); however, the benefits of the system for patients with severe acute liver injury (SLI) remain unclear. We have evaluated the clinical significance of the referral system for SLI patients. Patients with ALI/SLI who were consecutively and prospectively listed on the system between 2004 and 2018 were analyzed. Of the 371 ALI/SLI/ALF patients on the system, 124 satisfied the criteria for SLI; 34 of these 124 progressed to SLI after registration. Multivariate analysis using age, sex, AST, ALT, creatinine, total bilirubin, prothrombin, presence of hepatic encephalopathy (HE), and SLI at registration revealed that HE was associated with high mortality. Among the 23 patients who developed HE, five who progressed to SLI after registration showed an increased time to HE development compared with patients who had SLI at the time of registration. However, there was no significant difference in survival time after HE development. We concluded that early identification of SLI patients using the referral system increased the time from SLI diagnosis to HE development.

The patient was a 65-year-old man with alcoholic liver cirrhosis who had been admitted to hospital 5 times for repeated and recurrent overt hepatic encephalopathy (HE) despite numerous therapies, including disaccharide, branched-chain amino acid (BCAA) formula, L-carnitine and zinc. After the additional administration of rifaximin (1,200 mg/day orally), his consciousness level was well controlled for 3 years without any adverse effects. The long-term administration of rifaximin may be useful and safe for managing recurrent overt HE, although the maintenance dosage and duration of rifaximin and safety should be evaluated in patients with ameliorated HE.

Background: Patients with autoimmune liver disease may feel anxiety towards vaccination for Severe Acute respiratory syndrome coronavirus-2 because of insufficient data regarding its efficacy and adverse effects. The aim of this study was to study how information-sharing regarding coronavirus disease 19 (COVID-19) affects anxiety towards the vaccine in patients with autoimmune liver disease.Methods: Information about COVID-19 and its vaccines provided to subjects with autoimmune liver disease, and change of anxiety to the vaccines after information-sharing were prospectively evaluated.Results: Seventy-one patients prospectively and consecutively registered between March 2021 and May 2021 were assessed. Information-sharing decreased patient anxiety scores towards vaccination from 46 to 23 (p < 0.01). A beneficial effect of information-sharing was confirmed via a visual analog scale (VAS). The correlation of VAS before information-sharing to change of VAS during the study was negative (rho = −0.405, p = 0.00046). There was no significant difference regarding the comparison of VAS to age, or medication use. Conclusion: Information-sharing improved anxiety towards vaccination in patients with autoimmune liver disease, especially in patients who felt strong anxiety before information-sharing.

AimWe aimed to establish a method that will identify patients at a high risk for progressive phenotype of fatty liver.MethodsPatients with fatty liver who underwent liver biopsy between July 2008 and November 2019 were included as cohort 1, and those who underwent abdominal ultrasound screening examination by general physicians between August 2020 and May 2022 served as cohort 2. According to the definition of metabolic dysfunction‐associated fatty liver (MAFLD), the subjects were classified by body mass index of ≥23, diabetes mellitus, and coexistence of two or more metabolic risk items. The progressive phenotype of MAFLD is defined by significant fibrosis complicated with either nonalcoholic fatty liver disease activity score ≥4 (BpMAFLD) or steatosis grade ≥2 by ultrasound examination (UpMAFLD).ResultsOne hundred sixty‐eight patients and 233 patients were enrolled in cohorts 1 and 2, respectively. In cohort 1, the prevalence of BpMAFLD was 0% in patients without a complicating factor (n = 10), 13% in those with one complicating factor (n = 67), 32% in those with two (n = 73), and 44% in those with all three complicating factors (n = 36). A logistic regression analysis revealed that factors in the MAFLD definition were significantly associated with BpMAFLD. In cohort 2, a criterion of two or more positive MAFLD definitions was found to have a 97.4% negative predictive value for the diagnosis of UpMAFLD.ConclusionPatients with two or more complicating factors in the MAFLD definition should have further evaluation for liver fibrosis.
