ABSTRACT
BACKGROUND: Given the increasing health concerns for patients with inflammatory bowel disease (IBD), amidst the COVID-19 pandemic, we investigated the impact of the pandemic on the anxiety and behavioral changes in Japanese patients with IBD. METHODS: We analyzed 3032 questionnaires from patients with IBD, aged 16 years or older visiting 30 hospitals and 1 clinic between March 2020 and June 2021. The primary outcome was the score of the anxiety experienced by patients with IBD during the pandemic. RESULTS: Participants reported a median age of 44 years; 43.3% of the patients were women. Moreover, 60.6% and 39.4% were diagnosed with ulcerative colitis and Crohn's disease, respectively, with a median disease duration of 10 years. Participants indicated an average of disease-related anxiety score of 5.1 ± 2.5 on a ten-point scale, with a tendency to increase, 1 month after the number of infected persons per population increased. The top three causes for anxiety were the risk of contracting COVID-19 during hospital visits, SARS-CoV-2 infection due to IBD, and infection by IBD medication. Factors associated with anxiety were gender (women), being a homemaker, hospital visit timings, mode of transportation (train), use of immunosuppressive drugs, and nutritional therapy. Most patients continued attending their scheduled hospital visits, taking their medications, experienced the need for a family doctor, and sought guidance and information regarding COVID-19 from primary doctors, television, and Internet news. CONCLUSIONS: Patients with IBD experienced moderate disease-related anxiety due to the pandemic and should be proactively informed about infectious diseases to relieve their anxiety.

Epinephrine local injection is a hemostatic procedure used in active diverticular bleeding that elicits vasoconstriction and tamponade effects. We compared the additional benefit of combination therapy with HSE-C (hypertonic saline epinephrine injection with clipping) to clipping monotherapy. Retrospective data on diverticular bleeding between 2011 and 2016 was reviewed. Those with an active bleeding source confirmed by colonoscopy (excluding non-bleeding vessels and adherent clots) who received either HSE-C or clipping were evaluated. Endpoints were rates of successful primary hemostasis, recurrent bleeding, and surgical intervention during hospitalization. A total of 320 patients with diverticular bleeding were evaluated, on which either HSE-C (n = 35) or clipping monotherapy (n = 18) was performed. Rates of successful primary hemostasis (91.4% vs. 66.7%, p = 0.048) and direct placement of endoclips (60.0% vs. 16.7%, p = 0.004) were significantly higher in the HSE-C group. Although not statistically significant, the HSE-C group had a higher rate of early rebleeding (18.8% vs. 8.3%, p = 0.653), while no difference was seen in the number of patients requiring surgery (11.4% vs. 5.5%, p = 0.651). HSE-C is associated with a higher rate of successful primary hemostasis for severe active diverticular bleeding but has no significant difference in reducing early recurrent bleeding or the number of patients requiring surgery, suggesting that hemostatic effects may be temporary.
ABSTRACT
A virulence bacterium, Helicobacter pylori, evolved parallel to its host human, therefore, can work as a marker for tracing the human migration. We found H. pylori strains indigenous in the southernmost islands of Japanese Archipelago, Okinawa, and defined them as hspOkinawa and hpRyukyu. Genome data of the strains revealed that hspOkinawa diverged from other East Asian strains about 20,000 years ago, and that hpRyukyu diverged about 45,000 years ago. The closest strains of hpRyukyu were found from Afghanistan, Punjab, and Nepal, which suggest this strain originated in the central Asia and traveled across the Eurasian continent during Paleolithic era. The divergence date of hpRyukyu corresponds with human fossil records in Okinawa. Although it is controversial from human DNA analyses whether descendants of the Paleolithic migrants remain in the modern Japanese population, this study reveals that the bacterium of Paleolithic origin remains in the stomachs of current Japanese.

ABSTRACT
BACKGROUND: Capsule endoscopy can be used to identify the early stage of small bowel Crohn's disease (CD). We evaluated significant small bowel capsule endoscopy (SBCE) findings that can lead to early diagnosis of CD. METHODS: We retrospectively accumulated clinical and SBCE data of 108 patients (63 with and 45 without CD). Types of small bowel mucosal injuries, including erosion, ulceration, and cobblestone appearance, and the alignment of diminutive lesions were compared between patients with and without CD. Inter- and intra-observer agreement in the determination of lesions was assessed in 25 pairs of SBCE from the two groups. RESULTS: Under SBCE, cobblestone appearance (33% vs. 2%, p < 0.0001), longitudinal ulcers (78% vs. 20%, p < 0.0001), and irregular ulcers (84% vs. 60%, p < 0.01) were more frequently found in patients with CD. Linear erosion (90% vs. 38%, p < 0.0001) and irregular erosion (89% vs. 64%, p < 0.005) were also more frequent in patients with CD. Furthermore, circumferential (75% vs. 9%, p < 0.0001) and longitudinal (56% vs. 7%, p < 0.0001) alignment of diminutive lesions, mainly observed in the 1st tertile of the small bowel, was more frequent in patients with CD. Good intra-observer agreement was found for ulcers, cobblestone appearance, and lesion alignment. However, inter-observer agreement of SBCE findings differed among observers. CONCLUSIONS: Circumferential or longitudinal alignment of diminutive lesions, especially in the upper small bowel, may be a diagnostic clue for CD under SBCE, while inter-observer variations should be cautiously considered when using SBCE.

OBJECTIVES: The prevalence of pediatric Crohn's disease (CD) is increasing in Japan and other countries, and many patients are unresponsive to or do not tolerate current treatment options. This study aimed to investigate the efficacy, safety, and pharmacokinetic profile of infliximab (IFX) in pediatric patients with moderate-to-severe CD and inadequate response to existing treatment. STUDY DESIGN: This was an open-label, uncontrolled, multicenter Phase 3 study conducted at nine sites in Japan between April 2012 and March 2015. Pediatric patients (aged 6-17 years) with moderate-to-severe CD were treated with IFX 5 mg/kg at Weeks 0, 2, and 6, and at 8-week intervals thereafter until Week 46, with final evaluation at Week 54. IFX dose was increased to 10 mg/kg in patients who showed loss of response to IFX from Week 14 onwards. RESULTS: A total of 14 patients fulfilled eligibility criteria and were treated. Dose-escalation criteria were met by five patients who then received 10 mg/kg IFX. The remaining nine patients continued to receive an IFX dose of 5 mg/kg. IFX rapidly improved clinical symptoms and its effect was maintained for up to 54 weeks. Overall Pediatric Crohn's Disease Activity Index (PCDAI) response rate was 85.7%, and overall PCDAI remission rate was 64.3%. Three out of five patients who increased IFX dose regained PCDAI remission by retrieval of serum IFX concentration. Adverse events and serious adverse events occurred in 100.0% and 14.3% of patients, respectively. There was no substantial difference in the safety profiles of patients taking a constant dose of 5 mg/kg and those taking an increased dose of 10 mg/kg. CONCLUSIONS: These findings support the effective use of IFX in the treatment of pediatric patients with CD where other treatments have proven ineffective.

Crohn's disease (CD) involves chronic inflammation in the gastrointestinal tract due to dysregulation of the host immune response to the gut microbiome. Even though the host-microbiome interactions are likely contributors to the development of CD, a few studies have detected genetic variants that change bacterial compositions and increase CD risk. We focus on one of the well-replicated susceptible genes, tumor necrosis factor superfamily member 15 (TNFSF15), and apply statistical analyses for personal profiles of genotypes and salivary microbiota collected from CD cases and controls in the Ryukyu Islands, southernmost islands of the Japanese archipelago. Our association test confirmed the susceptibility of TNFSF15 in the Ryukyu Islands. We found that the recessive model was supported to fit the observed genotype frequency of risk alleles slightly better than the additive model, defining the genetic effect on CD if a pair of the chromosomes in an individual consists of all risk alleles. The combined analysis of haplotypes and salivary microbiome from a small set of samples showed a significant association of the genetic effect with the increase of Prevotella, which led to a significant increase of CD risk. However, the genetic effect on CD disappeared if the abundance of Prevotella was low, suggesting the genetic contribution to CD is conditionally independent given a fixed amount of Prevotella. Although our statistical power is limited due to the small sample size, these results support an idea that the genetic susceptibility of TNFSF15 to CD may be confounded, in part, by the increase of Prevotella.

We report the complete genome sequences of eight Helicobacter pylori strains isolated from patients with gastrointestinal diseases in Okinawa, Japan. Whole-genome sequencing and DNA methylation detection were performed using the PacBio platform. De novo assembly determined a single, complete contig for each strain. Furthermore, methylation analysis identified virulence factor genotype-dependent motifs.
ABSTRACT
The migration of Kirschner wires (K-wires) is a rare complication. We herein present a case of an inflammatory polyp in the colon caused by the migration of a K-wire following fixation of a pelvic fracture. Surgery was carried out to remove the K-wire through an incision at the level of the left iliac bone. Simultaneous endoscopic clipping of the colonic wound was also performed. The patient's postoperative course was uneventful. Although very rare, migration of devices should be considered in patients with a previous history of orthopedic surgery.

BACKGROUND: Various noninvasive tests have been studied to screen for patients with Crohn's disease (CD), and were found to have limited accuracy and sensitivity, particularly in Asian populations. The aim of our study was to explore the possible diagnostic utility of antibodies to the CD peptide (ACP) in patients with CD. METHODS: In a multicenter study using enzyme-linked immunosorbent assay, serum ACP levels were determined in 196 patients with CD, 210 with ulcerative colitis, 98 with other intestinal diseases, 132 with other inflammatory diseases, and 183 healthy controls. and then examined for correlation to clinical variables. The diagnostic utility of ACP was evaluated by receiver operating characteristics analysis and compared with anti-Saccharomyces cerevisiae antibodies (ASCA). RESULTS: ACP levels were significantly elevated in the CD patients, but not in the other groups that included UC, other intestinal diseases, other inflammatory diseases and the healthy controls. Among these other groups, ACP levels were not significantly different. In the CD patients, ACP had a higher sensitivity and specificity (63.3 and 91.0 %, respectively) than ASCA (47.4 and 90.4 %). ACP levels were negatively associated with disease duration, but not with CDAI, disease location, or medical treatment. CONCLUSIONS: ACP, a newly proposed serologic marker, was significantly associated with CD and was highly diagnostic. Further investigation is needed across multiple populations of patients and ethnic groups, and more importantly, in prospective studies.

AIM: To evaluate the protective effects of fucoidan on oxidative stress-induced barrier disruption in human intestinal epithelial cells. METHODS: In Caco-2 cell monolayer models, the disruption of barrier function by oxidative stress is mediated by H2O2. The integrity of polarized Caco-2 cell monolayers was determined by measuring the transepithelial resistance (TER) and permeability was estimated by measuring the paracellular transport of FITC-labeled 4-kDa dextran (FD4). The protective effects of fucoidan on epithelial barrier functions on polarized Caco-2 cell monolayers were evaluated by TER and FD4 flux. The expression of tight junction (TJ) proteins was assessed using reverse-transcription polymerase chain reaction (RT-PCR) and immunofluorescence staining. RESULTS: Without H2O2 treatment, fucoidan significantly increased the TER compared to control (P < 0.05), indicating a direct enhancement of intestinal epithelial barrier function. Next, H2O2 disrupted the epithelial barrier function in a time-dependent manner. Fucoidan prevented the H2O2-induced destruction in a dose-dependent manner. Fucoidan significantly decreased H2O2-induced FD4 flux (P < 0.01), indicating the prevention of disruption in paracellular permeability. RT-PCR showed that Caco-2 cells endogenously expressed claudin-1 and -2, and occludin and that H2O2 reduced the mRNA expression of these TJ proteins. Treatment with fucoidan attenuated the reduction in the expressions of claudin-1 and claudin-2 but not occludin. Immunofluorescence staining revealed that the expression of claudin-1 was intact and high on the cell surface. H2O2 disrupted the integrity of claudin-1. Treatment with fucoidan dramatically attenuated the expression of claudin-1. CONCLUSION: Fucoidan enhanced intestinal epithelial barrier function by upregulating the expression of claudin-1. Thus, fucoidan may be an appropriate therapy for the treatment of inflammatory bowel diseases.

A 36-year-old woman presented with fever, diarrhea, and weight loss in April 2011. Upper GI endoscopy and colonoscopy showed a diffuse yellow-white shaggy mucosa in the second part of the duodenum and the ileum end, respectively. These lesions in these 2 locations were biopsied, and both specimens showed distended epithelial villi and massive infiltration of foamy macrophages in the lamina propria. PCR was performed to identify causative bacilli. DNA extracted from the duodenal mucosa showed a specific PCR product, confirming the diagnosis of Whipple's disease. The patient was treated with a 2-week course of ceftriaxone, followed by sulfamethoxazole/trimethoprim. After we started the treatment, the patient developed complications of infective endocarditis and meningitis. The patient was relieved of her symptoms using a combination of gentamicin, penicillin G, ampicillin, meropenem, and vancomycin.

Gastric antral vascular ectasia (GAVE) has been recognized as one of the important causes of occult and obscure gastrointestinal bleeding. The diagnosis is typically made based on the characteristic endoscopic features, including longitudinal row of flat, reddish stripes radiating from the pylorus into the antrum that resemble the stripes on a watermelon. These appearances, however, can easily be misinterpreted as moderate to severe gastritis. Although it is believed that capsule endoscopy (CE) is not helpful for the study of the stomach with its large lumen, GAVE can be more likely to be detected at CE rather than conventional endoscopy. CE can be regarded as "physiologic" endoscopy, without the need for gastric inflation and subsequent compression of the vasculature. The blood flow of the ecstatic vessels may be diminished in an inflated stomach. Therefore, GAVE may be prominent in CE. We herein describe a case of active bleeding from GAVE detected by CE and would like to emphasize a possibility that CE can improve diagnostic yields for GAVE.
ABSTRACT
BACKGROUND AND AIM: Helicobacter pylori cagA can be classified into mainly two types (East-Asian-type and Western-type cagA) according to the repeat regions located in the 3' region. Recent studies showed that the Western-type cagA in strains from Okinawa, Japan formed a different cluster (J-Western-type cagA subtype). It has also been reported that J-Western-type cagA possesses a 12-bp insertion located in the 5' region of cagA sequence. METHODS: The prevalence of 12-bp insertion in cagA in Okinawa and the United States (U.S.) was examined by DNA sequencing. The primer pair that can detect the 12-bp insertion only by polymerase chain reaction was then designed. The prevalence of strains with 12-bp insertion was examined in 336 strains isolated from Okinawa by polymerase chain reaction. RESULTS: In case of Western-type cagA/vacA s1m2 strains, the prevalence of 12-bp insertion was significantly higher in strains isolated from Okinawa than that from the U.S. (P = 0.002). Phylogenetic tree showed that strains with 12-bp insertion formed two individual clusters within J-Western-type cagA subtype; one is from Okinawa and another is from the U.S. The designed primer set showed high sensitivity (100%) and specificity (90.8%) in Okinawa. The 12-bp insertion was found in 23.7%, 14.3%, 4.2%, and 4.0% of strains with duodenal ulcer (DU), gastritis, gastric cancer, and gastric ulcer (GU), respectively (P < 0.001 for DU vs GU) in Okinawa. CONCLUSIONS: Although the mechanisms are unknown, the presence of 12-bp insertion was associated with the presence of DU and might have a suppressive action on GU and gastric cancer.

BACKGROUND: Helicobacter pylori dupA can be divided into two types according to the presence or absence of the mutation. In addition, full-sequenced data revealed that dupA has two types with different lengths depend on the presence of approximately 600 bp in the putative 5' region (presence; long-type and absence; short-type), which has not been taken into account in previous studies. METHODS: A total of 319 strains isolated from Okinawa, the south islands of Japan, were included. The status of dupA and cagA was determined by polymerase chain reaction. The presence of mutations in long-type dupA was determined by DNA sequencing. RESULTS: The prevalence of long-type dupA was 26.3% (84/319). Sequence analysis showed that there were only six cases (7.1%) with point mutations lead to stop codon among 84 long-type dupA strains studied. Interestingly, intact long-type dupA without frameshift mutation, but not short-type dupA, was significantly associated with gastric ulcer and gastric cancer than gastritis (p = .001 and p = .019, respectively). After adjustment by age, gender, and cagA, the presence of intact long-type dupA was significantly associated with gastric ulcer and gastric cancer compared with gastritis (odds ratio [OR] = 3.35, 95% confidence interval [CI] = 1.55-7.24 and OR = 4.14, 95% CI = 1.23-13.94, respectively). CONCLUSIONS: Intact long-type dupA is a real virulence marker for severe outcomes in Okinawa, Japan. The previous information gained from PCR-based methods without taking long-type dupA into account must be interpreted with caution.

AIM: The main aim of this study was to determine whether questionnaire evaluations of clinical symptoms in gastroesophageal reflux disease were useful to assess proton pump inhibitor therapy. METHODS: A total of 185 Japanese patients (men, 88; women, 97; age: 55.7 ± 16.1 years) with gastroesophageal reflux disease were enrolled. The patients were divided based on the frequency scale for symptoms of gastroesophageal reflux disease: severe symptoms with scores ≥8 and mild symptoms with scores ≤7. Quality of life was evaluated with the Medical Outcomes Study 8-Item Short-Form Health Survey. All patients were treated with a proton pump inhibitor, rabeprazole (10 mg/day), for 8 weeks. RESULTS: Patients were classified into four groups: reflux esophagitis with severe symptoms (n = 92, 49.7%); reflux esophagitis with mild symptoms (n = 17, 9.2%); non-erosive reflux disease with severe symptoms (n = 66, 35.7%); and non-erosive reflux disease with mild symptoms (n = 10, 5.4%). The dysmotility score was high in non-erosive reflux disease with severe symptoms compared with reflux esophagitis with severe symptoms (9.1 ± 0.5 vs 6.8 ± 0.5, P < 0.05). The symptom score and quality of life in the severe symptoms groups for both reflux esophagitis and non-erosive reflux disease were significantly improved by rabeprazole treatment. Only the reflux score was improved by rabeprazole in the reflux esophagitis with mild symptoms group; no therapeutic effect was observed for the non-erosive reflux disease with mild symptoms group. CONCLUSIONS: Low scores on the frequency scale for the symptoms of gastroesophageal reflux disease indicate poor responsiveness to proton pump inhibitor treatment, and high scores indicate good responsiveness.

Abdominal tuberculosis (TB) is the sixth most common location of extrapulmonary TB involvement. Because its symptoms and signs are often nonspecific, laboratory and imaging findings mimic other diseases including carcinoma. Therefore, the diagnosis of abdominal TB is challenging. We herein report a case of 74-year-old woman who presented with abdominal pain, anorexia, and weight loss. She had been given a diagnosis of pancreatic head carcinoma. Laboratory data was unremarkable except for elevated erythrocyte sedimentation rate, CA125, and sIL-2R. CT scan revealed multiple enlarged peripancreatic lymph nodes and concentric thickening of the ileocecal wall. Colonoscopy demonstrated deformed ileocecal valve and erosions. Histological examination showed epithelioid granulomas. Laparoscopy revealed numerous white tubercles diffusely covering the parietal peritoneum. Histopathological images of peripancreatic lymph node revealed large multiple caseating granulomas surrounded by Langhans_giant cells and epithelioid cells. Polymerase chain reaction and culture of the specimens were positive for Mycobacterium tuberculosis. Tuberculous lymphadenopathy, colitis, and peritonitis were finally diagnosed. She responded well to the antitubercular treatment.
