BACKGROUND: Mucosal healing, confirmed by endoscopic evaluation, is the long-term goal of treatment for Crohn's disease (CD). Leucine-rich alpha-2 glycoprotein (LRG) is a new serum biomarker correlated with disease activity in inflammatory bowel disease. However, studies evaluating its relationship with CD, particularly in the context of small intestinal lesions, are scarce. The aim of this study was to investigate the accuracy of LRG in assessing endoscopic activity, especially remission, in patients with CD. METHODS: Between July 2020 and March 2021, 72 patients with CD who underwent LRG testing and double-balloon endoscopy at the same time were included. Endoscopic activity was evaluated using the applied Simple Endoscopic Score for Crohn's disease, including small intestine lesions. The relationship of LRG with clinical symptoms and endoscopic activity was assessed, and its predictive accuracy was evaluated. RESULTS: Leucine-rich alpha-2 glycoprotein showed a significant positive correlation with endoscopic activity (r = 0.619, P < .001), even in patients with active lesions in the small intestine (r = 0.626, P < .001). Multivariate logistic regression revealed that LRG was the only factor associated with endoscopic remission. An LRG cutoff value of 8.9 μg/mL had a sensitivity of 93.3%; specificity of 83.3%; positive predictive value of 96.6%; negative predictive value of 71.4%; accuracy of 91.7%; and area under the curve of 0.904 for the prediction of endoscopic remission. CONCLUSIONS: Leucine-rich alpha-2 glycoprotein can be used in assessing endoscopic activity and is a reliable marker of endoscopic remission in CD patients. It can be an intermediate target in the treatment of CD.

Background: Like esophageal varices, cardiac varices are often treated with endoscopic variceal ligation (EVL). However, we previously reported that EVL for cardiac varices may be associated with a high risk of rebleeding from the ulcer if the O-ring spontaneously drops off early. The efficacy and safety of para-variceal endoscopic injection sclerotherapy (EIS) with polidocanol for the treatment of cardiac varices in children and adolescents were evaluated. Methods: Eleven patients under 18 years of age with portal hypertension who underwent para-variceal EIS with polidocanol for cardiac varices with red signs, which were considered to be at high risk of bleeding, were retrospectively reviewed. Results: One session of para-variceal polidocanol-EIS was performed for each of the 11 patients. One patient experienced temporary hypoxia due to aspiration of saliva when the tracheal intubation tube was removed after the procedure but recovered by endotracheal suctioning; there were no other adverse events. In six of the eight cases in which efficacy could be evaluated, eradication of cardiac varices was achieved. Conclusion: Para-variceal polidocanol-EIS may be considered instead of EVL for small cardiac varices with red signs in pediatric patients with cardiac varices.

Background and Aim: Immune-related liver injury (liver-irAE) is a clinical problem with a potentially poor prognosis. Methods: We retrospectively collected clinical data from patients treated with immune checkpoint inhibitors between September 2014 and December 2021 at the Nagoya University Hospital. Using an unsupervised machine learning method, the Gaussian mixture model, to divide the cohort into clusters based on inflammatory markers, we investigated the cumulative incidence of liver-irAEs in these clusters. Results: This study included a total of 702 patients. Among them, 492 (70.1%) patients were male, and the mean age was 66.6 years. During the mean follow-up period of 423 days, severe liver-irAEs (Common Terminology Criteria for Adverse Events grade ≥ 3) occurred in 43 patients. Patients were divided into five clusters (a, b, c, d, and e). The cumulative incidence of liver-irAE was higher in cluster c than in cluster a (hazard ratio [HR]: 13.59, 95% confidence interval [CI]: 1.70–108.76, P = 0.014), and overall survival was worse in clusters c and d than in cluster a (HR: 2.83, 95% CI: 1.77–4.50, P < 0.001; HR: 2.87, 95% CI: 1.47–5.60, P = 0.002, respectively). Clusters c and d were characterized by high temperature, C-reactive protein, platelets, and low albumin. However, there were differences in the prevalence of neutrophil count, neutrophil-to-lymphocyte ratio, and liver metastases between both clusters. Conclusions: The combined assessment of multiple markers and body temperature may help stratify high-risk groups for developing liver-irAE.

Background: We aimed to investigate the factors associated with improvement of liver functional reserve after sustained virological response using interferon-free, direct-acting antiviral combination treatment in patients with compensated, severe fibrosis. Methods: Between September 2014 and April 2020, 492 patients received direct-acting antiviral combination treatment in our hospital. Among them, 173 patients who had severe fibrosis based on a fibrosis-4 index ≥3.25, showed sustained virological response after treatment. We investigated the dynamic change in albumin-bilirubin score and the baseline factors associated with its improvement, 48 weeks after treatment. Results: The baseline significant factors associated with albumin-bilirubin ≦ −0.5 were lower albumin (HR: 15.625, 95% CI: 4.273–58.824, P <.001), higher hepatitis C virus RNA (HR: 4.995, 95% CI: 1.882–13.260, P =.001), and higher alpha-fetoprotein (HR: 1.033, 95% CI: 1.011–1.055, P =.003). Patients with alpha-fetoprotein ≧10 ng/mL showed significant improvement of albumin-bilirubin score from baseline to 48 weeks after treatment compared to those with alpha-fetoprotein <10 ng/mL (P <.001). Conclusions: Baseline serum alpha-fetoprotein might be a predictive factor for improvement of liver function after sustained virological response in patients with severe fibrosis.

Background and Aim: Double-balloon endoscopic retrograde cholangiography (DBERC) is a valuable procedure for patients with altered gastrointestinal anatomy. Nonetheless, it is time-consuming and burdensome for both patients and endoscopists, partly because route selection in the reconstructed bowel with complicating loop is challenging. Carbon dioxide insufflation enterography is reportedly useful for route selection in the blind loop. This prospective randomized clinical trial investigated the usefulness of carbon dioxide insufflation enterography for route selection by comparing it with conventional observation. Methods: Patients scheduled to undergo DBERC were consecutively registered. They were divided into carbon dioxide insufflation enterography and conventional groups via randomization according to stratification factors, type of reconstruction methods, and experience with DBERC. The primary endpoint was the correct rate of initial route selection. The secondary endpoints were the insertion time, examination time, amount of anesthesia drugs, and complications. Results: The correct rate of route selection was significantly higher in the carbon dioxide insufflation enterography group (23/25, 92%) than in the visual method (15/25, 60%) (P = 0.018). The insertion time was significantly shorter in the carbon dioxide insufflation enterography group than in the visual group (10.8 ± 11.1 min vs 29.8 ± 15.7 min; P < 0.001). No significant differences in complications were noted between the two groups. The amounts of sedatives and analgesics used were significantly lower in the carbon dioxide insufflation enterography group (P < 0.001 and P < 0.001, respectively). Conclusions: Carbon dioxide insufflation enterography can reduce the burden of DBERC on patients and endoscopists by shortening the examination time and reducing the amount of medication.

BACKGROUND: Ulcerative colitis involves an excessive immune response to intestinal bacteria. Whether administering prebiotic 1-kestose is effective for active ulcerative colitis remains controversial. AIMS: This randomised, double-blind, placebo-controlled pilot trial investigated the efficacy of 1-kestose against active ulcerative colitis. METHODS: Forty patients with mild to moderate active ulcerative colitis were randomly treated with 1-kestose (N = 20) or placebo (maltose, N = 20) orally for 8 weeks in addition to the standard treatment. The Lichtiger clinical activity index and Ulcerative Colitis Endoscopic Index of Severity were determined. Faecal samples were analysed to evaluate the gut microbiome and metabolites. RESULTS: The clinical activity index at week 8 was significantly lower in the 1-kestose group than in the placebo group (3.8 ± 2.7 vs. 5.6 ± 2.1, p = 0.026). Clinical remission and response rates were higher in the 1-kestose group than in the placebo group (remission: 55% vs. 20%, p = 0.048; response: 60% vs. 25%, p = 0.054). The Ulcerative Colitis Endoscopic Index of Severity at week 8 was not significantly different (2.8 ± 1.6 vs. 3.5 ± 1.6, p = 0.145). Faecal analysis showed significantly reduced alpha-diversity in the 1-kestose group, with a decreased relative abundance of several bacteria, including Ruminococcus gnavus group. The short-chain fatty acid levels were not significantly different between the groups. The incidence of adverse events was comparable between the groups. DISCUSSION: Oral 1-kestose is well tolerated and provides clinical improvement for patients with mild to moderate ulcerative colitis through modulation of the gut microbiome.

Despite treatment, hepatitis B surface antigen (HBsAg) persists in patients with chronic hepatitis B (CHB), suggesting the likely presence of the virus in the body. CD8+ T cell responses are essential for managing viral replication, but their effect on HBsAg levels remains unclear. We studied the traits of activated CD8+ T cells and HBV-specific CD8+ T cells in the blood of CHB patients undergoing nucleos(t)ide analog (NUC) therapy. For the transcriptome profiling of activated CD8+ T cells in peripheral blood mononuclear cells (PBMCs), CD69+ CD8+ T cells were sorted from six donors, and single-cell RNA sequencing (scRNA-seq) analysis was performed. To detect HBV-specific CD8+ T cells, we stimulated PBMCs from 26 donors with overlapping peptides covering the HBs, HBcore, and HBpol regions of genotype A/B/C viruses, cultured for 10 days, and analyzed via multicolor flow cytometry. scRNA-seq data revealed that CD8+ T cell clusters harboring the transcripts involved in the cytolytic functions were frequently observed in donors with high HBsAg levels. Polyfunctional analysis of HBV-specific CD8+ T cells utilized by IFN-γ/TNFα/CD107A/CD137 revealed that HBcore-specific cells exhibited greater polyfunctionality, suggesting that the quality of HBV-specific CD8+ T cells varies among antigens. Moreover, a subset of HBcore-specific CD8+ T cells with lower cytolytic potential was inversely correlated with HBsAg level. Our results revealed a stimulant-dependent qualitative difference in HBV-specific CD8+ T cells in patients with CHB undergoing NUC therapy. Hence, the induction of HBcore-specific CD8+ T cells with lower cytolytic potential could be a new target for reducing HBsAg levels.

Endoscopic injection sclerotherapy (EIS) for esophagogastric varices (EGV) was attempted for a 29-yearold man with extrahepatic portal vein obstruction. However, pipeline varices characterized by a large blood flow volume were present, and the sclerosant did not accumulate sufficiently in them. Transileocolic obliteration (TIO) using coils was performed, but some EGVs and palisading veins remained. Thus, EIS was performed once again immediately after TIO. Since a reduction in the intravariceal blood flow was achieved by preceding TIO, effective injection of sclerosant into the vessels was possible. For pipeline varices difficult to treat endoscopically, combination therapy with TIO may be effective.

Crohn’s disease patients suffer from symptoms originating from small bowel lesions, including strictures. As many of these patients also have a potential risk of surgery, it is important to consider various therapeutic strategies for small bowel lesions. We retrospectively analyzed the therapeutic effects of ustekinumab, interleukin-12 and -23 blocker, for small intestinal lesions and intestinal stenosis in order to contribute to the optimal management of Crohn’s disease. Patients who underwent total colonoscopy or small bowel endoscopy before and after the introduction of ustekinumab were enrolled in this study. The colonoscopy findings were evaluated by the simple endoscopic score for Crohn’s disease, and small bowel endoscopy findings were evaluated using the modified simple endoscopic score for Crohn’s disease. Endoscopic scores were compared before and after the introduction of ustekinumab and between the responders and non-responders to ustekinumab. Responders were defined as those whose Crohn’s disease activity index score at 24 weeks fell below 150 points, or those whose score decreased by more than 100 points from the pre-induction level. A total of 50 patients were enrolled in the study, and the number of responders was 35. Pre-induction simple endoscopic scores were lower for responders, but no significant difference was observed in the modified simple endoscopic scores. The total decrease in the endoscopic score was significantly higher in the responders for both the small and large intestine. Use of ustekinumab as a first-line treatment for patients with small bowel lesions or stricture-prone lesions may be a new treatment consideration in the future.

Objectives: The presence of myosteatosis is one factor associated with poor prognosis for patients with cirrhosis; however, the factors contributing to worsening myosteatosis are, to our knowledge, unknown. The aim of this study was to clarify the changes in myosteatosis, and the factors involved in these changes. Methods: The present study enrolled 178 patients with cirrhosis who underwent computed tomography twice to measure changes in skeletal muscle attenuation (SMA) at the L3 level. Factors associated with SMA and those associated with changes in SMA were examined. Results: Using linear multiple regression analysis, age (β = –0.22), skeletal muscle index (SMI; skeletal muscle area divided by height squared; β = 0.25), and visceral and subcutaneous fat indices (VFI and SFI; the visceral and subcutaneous fat areas at the umbilical level divided by height squared; β = –0.08, β = –0.06, respectively) were identified as associated with SMA. The 100-d change in SMA was –0.21 ± 1.29 Hounsfield units (HU). Changes in SMI and SMA were positively associated (R = 0.183, P = 0.014), whereas those in VFI and SMA were negatively associated (R = –0.172, P = 0.022). No association was noted between the 100-d changes in SFI and SMA. In patients whose SMI increased and VFI decreased, the 100-d change in SMA was 0.24 ± 1.82 HU, which was marginally different from that in patients whose SMI decreased and VFI increased (–0.44 ± 1.32 HU, P = 0.077). Conclusions: In patients with cirrhosis, myosteatosis progressed, and decreases in SMI and increases in VFI were correlated with its progression.

Patients with nonalcoholic fatty liver disease (NAFLD) have illness uncertainty. The purpose of this longitudinal study was to investigate the effect of the degree of illness uncertainty in patients with NAFLD on liver function values. We conducted a questionnaire survey and collected blood samples from outpatients with NAFLD. The items in the questionnaire were measured for illness uncertainty using the Japanese version of the Mishel Uncertainty in Illness Scale-Community (MUIS-C). Blood samples were collected at baseline and after 1 year. We divided the patients into two groups: one with high illness uncertainty and the other with low illness uncertainty. We then compared changes in alanine transaminase (ALT) and aspartate aminotransferase (AST) levels over time from baseline using multiple regression analysis. This study analyzed 148 patients with NAFLD; 75 were male and 73 were female, with a mean age of 58.4 ± 12.3 years. The group with higher illness uncertainty had significantly higher ALT and AST levels at 1 year (b =.185 and.183, respectively) than the group with lower illness uncertainty. High illness uncertainty in patients with NAFLD can lead to higher ALT and AST levels. Healthcare providers must focus on reducing illness uncertainty in patients with NAFLD.

Objectives: To our knowledge, the relationship between appetite and sarcopenia in patients with cirrhosis is unknown. The aims of this study were to examine the factors associated with decreased appetite and to clarify the relationship between appetite and sarcopenia. Methods: This study included 61 patients with cirrhosis. The patients were asked to describe their appetite using a numerical rating scale (NRS) from 0 (none at all) to 10 (most), with ≤5 defined as decreased appetite. The clinical characteristics, gastrointestinal symptoms as assessed using the Gastrointestinal Symptom Rating Scale, handgrip strength, and skeletal muscle area at the third vertebra were collected retrospectively. Sarcopenia was diagnosed according to the criteria of the Japan Society of Hepatology. The differences in these factors between patients with and without decreased appetite, and the factors associated with the presence of sarcopenia were examined. Results: Alcoholic liver disease was the most common etiology. The median Model for End-Stage Liver Disease score was 8 (interquartile range = 7 - 10) and hepatocellular carcinoma was present in 35 patients. Overall, 36% of the patients with cirrhosis had decreased appetite. Patients with decreased appetite had a higher frequency of abdominal pain and acid reflux–related symptoms and significantly lower handgrip strength than patients without, among both men (P = 0.034) and women (P = 0.017). The multivariate analysis identified a decrease in appetite as a significant factor associated with the presence of sarcopenia (NRS one increase, odds ratio, 0.701; 95% confidence interval, 0.502–0.977; P = 0.036). Conclusion: Decreased appetite was associated with the presence of sarcopenia.

There have been previous studies, especially in Western countries and even in some areas in Asia, about extra-intestinal manifestations (EIMs) and its link with the outcome of inflammatory bowel disease (IBD), which includes Crohn’s disease (CD), and ulcerative colitis (UC). This link is crucial when discussing a patient’s prognosis and important when dealing with UC management. The aim of this study was to clarify the most common comorbidities associated with UC, emphasizing immunologic comorbidities in Japan. This study was a retrospective analysis performed at Nagoya University Hospital. The data collection started in March, 2019, and continued for two years. We retrieved the medical records of 105 patients with UC diagnosis, from which the data of 176 EIMs were extracted and analyzed. Results showed that EIMs with UC in the active phase accounted for 43.7% of total EIMs. Twenty-six patients with immune-mediated inflammatory disease frequently had an active phase (odds ratio [OR] 3.84, 99% CI, 1.44–10.27). Comorbidities showing an active manifestation of symptoms and UC in the active phase were significantly correlated in patients with immunological comorbidities, such as peripheral arthritis (r = 0.97, p < 0.01) and rheumatoid arthritis (RA) (r = 0.99, p < 0.01), as well as in patients with primary sclerosis cholangitis (PSC) (r = 0.98, p < 0.01). In conclusion, this analysis suggests the importance of having full comprehension of how immunological comorbidities affect the natural development of UC, which is of vital importance to prevent further UC complications and properly adjust the management of the disease.

Aim: Conventionally, the skeletal muscle area with computed tomography (CT) attenuation ranging from −29 to +150 Hounsfield unit (HU) divided by height squared (the conventional skeletal muscle index [SMI]) was used as an index of skeletal muscle mass. However, it includes fat-infiltrated skeletal muscle, which is known to have poor function. This study aims to determine whether the low-fat SMI, which uses skeletal muscle mass with CT attenuation ranging from +30 to +150 HU, or conventional SMI appropriately reflects the function of skeletal muscle. Methods: We retrospectively analyzed 120 patients with cirrhosis whose handgrip strength was measured. Among them, 48 patients underwent a physical performance assessment such as liver frailty index (LFI) and short physical performance battery (SPPB), and 80 underwent quality of life (QOL) assessment. The relationships between each SMI and handgrip strength, LFI, SPPB, and QOL were evaluated. Results: Low-fat SMI was significantly correlated with handgrip strength (males, R = 0.393, p = 0.002; females, R = 0.423, p < 0.001) and LFI (males, R = −0.535, p = 0.035; females, R = −0.368, p = 0.039), whereas conventional SMI was not. When using low-fat SMI, patients with low skeletal muscle mass had significantly low handgrip strength, LFI, SPPB, and physical and social-related QOL score than those without. By contrast, no significant differences were found for any items when using conventional SMI. Conclusions: Low-fat SMI is a good index of skeletal muscle mass that appropriately reflects skeletal muscle function.
