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.

Background/Aim: A porous glass membrane-pumping emulsification device (GMD) enables the formation of a high-percentage water-in-oil emulsion with homogeneous and stable droplets. Although GMD is expected to improve the locoregional therapeutic effects of transarterial chemoembolization (TACE) in hepatocellular carcinoma (HCC), its effectiveness in the management of solitary HCC remains unclear. Patients and Methods: Patients treated for solitary HCCs (<5 cm) were retrospectively reviewed. A total of 46 patients who could not undergo liver resection and were unsuitable for radiofrequency ablation were included in this study. Among these, 22 patients underwent TACE using a GMD (GMD-TACE group) and 24 underwent stereotactic body radiotherapy (SBRT) using a robotic radiosurgery system (SBRT group). Local control rates were compared between the two groups. Results: The median HCC tumour size was 24 mm (range=12-50 mm) and 22 mm (range=8-39 mm) in the GMD-TACE and SBRT groups, respectively; however, the difference between the groups was not significant. Age, liver function test results, or Child-Pugh scores were not significantly different between the two groups. The rate of local control at 6 months after treatment was 100% in both groups. Although the 1-year local control rate was higher in the SBRT group (92.3%) than in the GMD-TACE group (81.8%), there was no significant difference in the log-rank test (p=0.654). No major treatment-related complications occurred in either group during the observation period. Conclusion: TACE with GMD could be considered an effective treatment option for the management of solitary HCC.

Background: Fecal microbiota transplantation (FMT) is a potential treatment for irritable bowel syndrome (IBS), but its efficacy in Japanese IBS patients is unknown. This study aimed to evaluate the efficacy, side effects, and microbiome changes following FMT in Japanese IBS patients. Methods: Seventeen Japanese patients with refractory IBS received FMT (4 donors) under colonoscopy. Responders were defined by an improvement in the IBS severity index (IBS-SI) of 50 points or more after 12 weeks. We evaluated the IBS-SI and Bristol Stool Form Scale (BSFS) and compared the diversity and microbiome before and 12 weeks after FMT. For the microbiome, we analyzed the V3–V4 region of the 16S rRNA gene. Results: IBS-SI decreased an average of 115.58 points after 12 weeks, and 10 patients (58.8%) were considered responders. Eight patients with diarrhea (66.7%) and three patients with constipation (60.0%) showed improvement in the BSFS. Two patients complained of mild abdominal pain, but there were no cases with severe side-effects. α-diversity was increased only in the responder group (p = 0.017). Patients who closely paralleled the donor microbiome had a higher rate of IBS-SI improvement. The relative abundance of Neisseria and Akkermansia increased and Desulfovibrio and Delftia were decreased in the responder group after FMT. Conclusions: Following FMT, about 60% of Japanese patients with IBS showed improvement in both the IBS-SI and BSFS, without severe side effects. Increased α-diversity and similarity to the donor microbiome after FMT may be associated with better treatment effects. Trial registration: This study was registered in the University Hospital Medical Information Network Clinical Trial Registration (UMIN000026363). Registered 31 May 2017, https://rctportal.niph.go.jp/s/detail/um?trial_id=UMIN000026363. The study was registered prospectively.

Background: The pathological evaluation of tissues with cholangitis is considered difficult, which can often occur after endoscopic sphincterotomy (EST) and endoscopic biliary stenting (EBS). This study aimed to evaluate the influence of a history of EST and EBS on the sensitivity of transpapillary forceps bile duct biopsy (TB) for bile duct adenocarcinoma. Methods: This retrospective study included consecutive cases of bile duct adenocarcinoma in which TB was performed before July 2020 until the number exceeded that required to support statistical and noninferiority analyses of the sensitivity of TB between patients with and without each variable. The incidence of postprocedural adverse events related to each factor was also investigated. Results: Overall, 280 samples were required in each group, and 437 subjects (792 samples) were included. The sensitivity of TB was 63.6% for the subjects and 59.6% for the biopsy samples. For the biopsy samples, the sensitivity did not differ significantly between samples from patients with and without a history of EST (59.1% vs. 58.9%, P = 0.952) and EBS (62.1% vs. 55.4%, P = 0.065). The sensitivity was significantly higher for samples from patients with jaundice (67.9% vs. 57.0%, P = 0.008). There were significantly fewer procedure-related adverse events in patients with a history of EST (10.8% vs. 19.0%, P = 0.017) and EBS (12.0% vs. 21.7%, P = 0.005). Conclusions: A history of EST or EBS did not influence sensitivity of TB but significantly decreased the incidence of adverse events. To safely and reliably perform TB to diagnose bile duct adenocarcinoma, planning, including for EST and EBS, is necessary.

The therapeutic goal in ulcerative colitis is mucosal healing, which requires improved non-invasive biomarkers to evaluate disease activity. Gelsolin is associated with several autoimmune diseases, and here, we aimed to analyze its usefulness as a serological biomarker for clinical and endoscopic activities in ulcerative colitis. Patients with ulcerative colitis (n = 138) who had undergone blood tests and colonoscopy were included. Serum gelsolin was measured using enzyme-linked immunosorbent assay, and correlation between the gelsolin level and clinical and endoscopic activities was examined. The serum gelsolin level in patients with ulcerative colitis was significantly lower than that in healthy subjects, and it decreased in proportion to increasing Mayo score and Mayo endoscopic subscore. The area under the curve for correlation between clinical and endoscopic remission and serum gelsolin level was higher than that for C-reactive protein. Furthermore, in C-reactive protein-negative patients, the serum gelsolin level was lower in the active phase than in remission. Our findings indicate that the serum gelsolin level correlates with clinical and endoscopic activities in ulcerative colitis, has a higher sensitivity and specificity than C-reactive protein, and can detect mucosal healing, suggesting that gelsolin can be used as a biomarker for ulcerative colitis.

Sarcopenia is thought to be related to the microbiome, but not enough reports in chronic liver disease (CLD) patients. In addition to the differences in microbiome, the role of the microbiome in the gut is also important to be clarified because it has recently been shown that the microbiome may produce branched-chain amino acids (BCAAs) in the body. In this single-center study, sixty-nine CLD patients were divided by skeletal muscle mass index (SMI) into low (L-SMI: n = 25) and normal (N-SMI: n = 44). Microbiome was analyzed from stool samples based on V3-4 region of bacterial 16S rRNA). L-SMI had a lower Firmicutes/Bacteroidetes ratio than N-SMI. At the genus level, Coprobacillus, Catenibacterium and Clostridium were also lower while the Bacteroides was higher. Predictive functional profiling of the L-SMI group showed that genes related to nitrogen metabolism were enriched, but those related to amino acid metabolism, including BCAA biosynthesis, were lower. The genes related to 'LPS biosynthesis' was also higher. The microbiome of CLD patients with low muscle mass is characterized not only by high relative abundance of gram-negative bacteria with LPS, but also by the possibility of low potential for amino acid synthesis including BCAAs.
