Abstract
BACKGROUND Consensus regarding the cutoff value of fecal calprotectin (FC) for predicting histological healing (HH) in ulcerative colitis (UC) is lacking. This study aimed to determine an optimal FC cutoff value for predicting HH in patients with UC with clinical and endoscopic remission. Furthermore, FC's predictability for prolonged clinical remission (CR) was investigated. METHODS Patients with UC in clinical and endoscopic remission, defined as a partial Mayo score (PMS) ≤ 2 points and a Mayo endoscopic subscore 0-1, were prospectively enrolled. Biopsy samples were evaluated by Geboes score (GS), with HH defined as a GS < 2.0. Patients were followed for 2 years or until relapse, defined as a PMS > 2 or medication escalation. RESULTS Seventy-six patients with UC were included. The median FC value in patients with HH (n = 40) was 56.2 µg/g, significantly lower than that in those with histological activity (118.1 µg/g; P < .01). The area under the curve (AUC) in a receiver operating characteristic (ROC) curve analysis to predict HH for FC was 0.71 (95% confidence interval [CI], 0.59-0.83), with an optimal cutoff value of 82.7 µg/g (73% sensitivity; 64% specificity; P < .01). Of 74 patients observed for 2 years, 54 (73%) had prolonged CR. In the ROC curve analysis, the AUC to predict prolonged CR for FC was 0.79 (95% CI, 0.68-0.90), equivalent to that for HH (0.73; 95% CI, 0.64-0.86; P = .40). The optimal FC cutoff value to predict prolonged CR was 84.6 µg/g (72% sensitivity; 85% specificity; P < .01). CONCLUSIONS Fecal calprotectin < 82 µg/g predicts HH in patients with UC with clinical and endoscopic remission. Low FC leads to prolonged CR, equivalent to HH.

Abstract
Gastrointestinal stromal tumors (GISTs) develop in the digestive tract, mainly in the stomach, small intestine, colon, or esophagus. However, primary tumors with the same pathologic features as GISTs have been reported to occur outside of the digestive tract and are called extragastrointestinal stromal tumor (EGIST). We herein report a rare case of EGIST arising from the greater omentum in a patient with abdominal pain caused by intraperitoneal bleeding from the tumor.

Abstract
Anti-tumor necrosis factor (TNF) α agents, widely used for the treatment of Crohn's disease (CD), can sometimes induce skin-associated adverse events, which mainly include psoriasis-like eruptions, eczema, and cutaneous infections. In contrast, purpura caused by vasculitis is rarely seen. We herein report a unique case of leukocytoclastic vasculitis induced by infliximab administered for CD in which intermittent purpura development was noted. Fluorescent immunostaining showed no immunoglobulin A deposition on the vessel walls. No purpura was initially seen after starting infliximab, but it appeared approximately 10 months later; however, administration did not have to be discontinued, and the condition was later resolved. The present findings provide important details regarding vasculitis induced by anti-tumor necrosis factor-α agent administration.

Abstract
High rates of co-existing irritable bowel syndrome (IBS) and headache have been reported in western countries. We investigated that comorbidity in individuals in Japan, along with anxiety and depression in subjects with and without IBS symptoms and/or headache.This cross-sectional study was performed from April 2012 to January 2013 at the Matsue Seikyo General Hospital Health Check Center. Questionnaires concerning symptoms related to IBS (Rome III) and headache, as well as anxiety/depression score were sent to individuals scheduled to undergo an annual health check-up, then returned during the visit and analyzed in a blinded manner.A total of 2885 individuals returned completed questionnaires and were enrolled, of whom 218 (7.6%) met the IBS criteria. The rates of co-existing headache in subjects with and without IBS symptoms were 44.0% (96/218) and 22.9% (611/2667), respectively, indicating a significantly higher rate of co-existing headache in subjects with as compared to without IBS (odds ratio [OR] 2.65, P < .001). Furthermore, the percentage of subjects with anxiety along with comorbid IBS symptoms and headache was significantly greater as compared to those with IBS (OR 3.01, P = .001) or headache (OR 2.41, P < .001) alone. Unlike anxiety, the percentage of subjects with depression was not significantly different among the IBS/non-headache, non-IBS/headache, and IBS/headache groups.Subjects with IBS symptoms had a higher rate of co-existing headache as compared to those without IBS. Furthermore, those with comorbid IBS symptoms and headache had a greater association with anxiety than with depression, as compared to those with only IBS or headache.

Abstract
BACKGROUND Non-islet cell tumor hypoglycemia (NICTH) is a rare paraneoplastic syndrome that secretes incompletely processed high molecular weight insulin growth factor 2 (big-IGF2), which results in stimulation of the insulin receptor and subsequently induces hypoglycemia. Gastrointestinal stromal tumor (GIST) is a common intestinal mesenchymal neoplasm of the gastrointestinal tract. The most frequent site of GIST is the stomach; NICTH induced by IGF2-producing stomach GISTs is rare. CASE PRESENTATION An 84-year-old man was admitted to the hospital due to impaired consciousness (JCS II-10) in the morning. At the time of admission, his serum glucose was 44 mg/dL; his consciousness was restored with 20 ml of 50% glucose. To avoid hypoglycemia, a continuous intravenous infusion of glucose as well as dietary intervention was required. At the time of hypoglycemia, the levels of insulin and C-peptide were suppressed. Additionally, IGF1 levels were below the normal range. Abdominal computed tomography revealed that he had a large lobulated mass (116 × 70 × 72 mm) around the gastric corpus. Pathological analysis of biopsy specimens identified disarray of spindle cells and positivity for c-kit as well as strong positivity for DOG-1. Further analysis revealed high levels of Ki-67 (Mib-1 index: 15.5%) and mitotic index (7/50HPF); the tumor was diagnosed as high-risk GIST, and complete surgical resection was performed. Hypoglycemia resolved immediately after tumor resection. The resected tumor specimen was positive for IGF2 staining, and big-IGF2 (11-18 kDa) was detected in preoperative serum and tumor samples; the patient was diagnosed with NICTH due to an IGF2-producing tumor. CONCLUSIONS NICTH is rare in GIST of the stomach; however, the large GIST could produce big-IGF2 and subsequently cause severe hypoglycemia, requiring prompt evaluation and complete tumor resection.

Abstract
Objective: Quiescent ulcerative colitis (UC) patients often have irritable bowel syndrome (IBS)-like symptoms and we recently showed that the prevalence of IBS-like symptoms in UC patients in clinical remission was significantly higher as compared to healthy control subjects. However, the prevalence of functional dyspepsia (FD)-like symptoms in quiescent UC patients remains unknown. The purpose of this study was to evaluate the prevalence of FD-like symptoms and the overlap with IBS-like symptoms in such patients.Materials and Methods: We reanalyzed the records of UC patients in remission using the subject cohort from our previous study. Clinical remission was defined as a clinical activity index (CAI) value ≤4 for at least 6 months. Diagnoses of FD- and IBS-like symptoms were evaluated by questionnaire according to the Rome III criteria.Results: One hundred seventy-two UC patients in clinical remission and 330 healthy control subjects were analyzed. Of the 172 patients, 9 (5.2%) met the criteria of FD, which was comparable with the controls (22/330, 6.7%). The prevalence rate of FD-like symptoms in UC patients with IBS-like symptoms (7/46, 15.2%) was lower as compared to that of the control subjects (6/16, 37.5%). On the other hand, a high percentage of the UC patients with FD-like symptoms also had IBS-like symptoms (7/9, 77.8%).Conclusions: Although the prevalence of FD-like symptoms in quiescent UC patients with IBS-like symptoms was low, UC patients with FD-like symptoms frequently had IBS-like symptoms.

Abstract
We herein report two cases of eosinophilic granulomatosis with polyangiitis (EGPA) initially diagnosed as eosinophilic gastroenteritis (EGE) based solely on endoscopic biopsy results. One year after the EGE diagnosis, one patient presented with multiple purpura, and skin biopsy findings resulted in a change of the diagnosis to EGPA. In another patient, multiple skin and colonic ulcerations emerged eight years after the diagnosis of EGE, at which time histological examinations of endoscopic biopsy specimens revealed vasculitis, and the diagnosis was changed to EGPA. Physicians should be aware of the possible existence of EGPA in cases diagnosed as EGE.

Abstract
Foreign body granuloma due to retained surgical sponge (gossypiboma) with penetration into the small intestine is very rare. Cases of gossypiboma in the abdominal cavity have sometimes been reported, yet the correct incidence has not been determined, only estimated to occur in one of every 1,000 to 1,500 intra-abdominal operations. Acute abdomen may be observed in some cases, requiring treatment. We herein introduce the case of a 70-year-old woman with gossypiboma penetrating into the small intestine presented with anemia and hematochezia. She had a history of emergency laparotomy for ectopic pregnancy several decades ago. A dynamic contrast-enhanced computed tomography revealed a hypovascular mass containing air bubbles that continued to the small intestine approximately 50 mm in size in the right lower abdomen. In addition to describing the presentation and outcome of our patient, we review the image findings of gossypiboma.

Abstract
As a rarely recognized foreign body in the upper gastrointestinal tract, rice cake frequently requires endoscopic removal. We herein report six patients with characteristic sonography, computed tomography (CT), spectroscopy, endoscopy, and histological findings. A review of all published cases, including ours, revealed that retained rice cake in the stomach typically shows the following: abdominal pain (93.3%), mucosal injury (93.3%) with bleeding (42.9%); high-density (120-206 Hounsfield units) CT findings; and indication for endoscopy (80%). In the esophagus, hot, toasted rice cake causes thermal injury. Primary physicians should be aware of this popular-food-induced, but rare, disorder.

Abstract
Fecal calprotectin level in ulcerative colitis patients is correlated with endoscopic findings. However, its association with various ulcerative colitis disease types has not been elucidated. In the present study, we investigated the correlation of fecal calprotectin level with endoscopic findings as compared to blood biomarkers according to ulcerative colitis disease type. Fecal calprotectin as well as the blood biomarkers: C-reactive protein (CRP), white blood count (WBC), erythrocyte sedimentation rate (ESR), hemoglobin, platelet count (PLT), and serum albumin (Alb) were measured in patients who underwent a complete colonoscopy. Disease type was divided into proctitis, left-sided colitis, and extensive colitis. Correlations of fecal calprotectin and blood biomarker levels with Mayo endoscopic subscore were analyzed. A total of 186 colonoscopy examinations were performed in 124 patients with ulcerative colitis. Fecal calprotectin level showed a significant correlation with Mayo endoscopic subscore regardless of disease type (proctitis, r = 0.54, p<0.01; left-sided colitis, r = 0.75, p<0.01; extensive colitis, r = 0.78, p<0.01), and clearly discriminated inactive (Mayo endoscopic subscore 0) from active stages (Mayo endoscopic subscore 1–3). On the other hand, none of the examined blood biomarkers showed a correlation with Mayo endoscopic subscore in the proctitis group, while weak correlations of several biomarkers (CRP, WBC, ESR, PLT and Alb) with Mayo endoscopic subscore were found in left-sided colitis and extensive colitis cases. This is the first report to elucidate the capabilities of fecal calprotectin and blood biomarkers as endoscopic surrogate markers according to ulcerative colitis disease type.

Abstract
411 Background: FOLFIRINOX (FFX) is a standard therapy for unresectable/recurrent pancreatic cancer, but it is associated with a high frequency of severe adverse events, especially blood toxicity. Human pegylated granulocyte colony-stimulating factor (PEG-G-CSF) can reduce the outpatient frequency during outpatient chemotherapy. However, there are few reports on the effectiveness of PEG-G-CSF in preventing febrile neutropenia during FFX. We retrospectively investigated the usefulness of PEG-G-CSF in reducing the incidence of FN during FFX. Methods: From June 2014 to January 2017, 40 patients with unresectable pancreatic cancer received FFX (including modified FFX) at our hospital. Twenty-three patients were administered PEG-G-CSF as primary/secondary preventive therapy (G group) and 17 were not administered any G-CSF (NG group). Results: The median patient ages in the G and NG groups were 65 (range, 48-78) and 63 (range, 42-81) years, respectively, and the male to female ratios were 13:10 and 11:6, respectively. There were 13 and 10 patients, respectively, in the G group with performance statuses of 0 and 1 and 8 and 9 such patients, respectively, in the NG group. Seventeen and five patients in the G and NG groups, respectively, had metastatic disease and six and two patients, respectively, had locally advanced disease. The respective response rates (RRs) in the G and NG groups were 30% and 6% (p = 0.0608), and the respective disease control rates (DCRs) were 30% and 41% (p = 0.0407). The median progression-free survivals in the G and NG groups were 7.3 (95% confidence interval [CI], 3–9.4) and 4.5 (95% CI, 1.9–8.5) months, respectively (p = 0.173), and the respective overall survivals were 16.9 (95% CI, 10.2–NA) and 14.2 (95% CI, 7.8–20.5) months (p = 0.302). Conclusions: The DCR was significantly greater in the G group than in the NG group, and the RR tended to be greater in the G group than in the NG group. A high tumor shrinking effect of FFX with PEG-G-CSF indicated that it might be useful as a neoadjuvant chemotherapy. A prospective study is needed to examine first-line chemotherapy in unresectable/recurrent pancreatic cancer and neoadjuvant chemotherapy in borderline/locally advanced pancreatic cancer.

Abstract
Aim: Few reports of the prophylactic use of soft coagulation with hemostatic forceps for postendoscopic papillectomy hemorrhage (PEPH) have been presented. The aim of this study was to clarify the utility of that procedure for prophylaxis. Materials and Methods: From April 2009 to March 2012, PEPH was treated in four patients after the development of the condition with a conventional procedure at our institution. Thereafter, from April 2012 to March 2016, soft coagulation using hemostatic forceps was performed as prophylactic hemostasis following an EP in five patients. For the latter procedure, the hemostatic forceps device (FD411‑QR, Olympus, Tokyo, Japan) was used in a closed position, with the coagulation wave set at 60 W (VIO 300D; ERBE, Tubingen, Germany). The primary outcome was the onset of PEPH, which was defined as a decrease in hemoglobin ≥2 g/dL after EP. Secondary endpoints were the success rate and the incidence of adverse events of soft coagulation using hemostatic forceps for emergency bleeding cases after EP. Results: The incidence of PEPH was 20% (1 of 5 cases) in the prophylactic procedure group, which was lower than that in the conventional procedures group (75%, 3 of 4 cases), though the difference was not statistically significant (P = 0.206, Fisher’s exact test). All cases of PEPH were successfully treated by soft coagulation using hemostatic forceps. Conclusion: Soft coagulation with hemostatic forceps may be suitable for use as a routine technique following EP to prevent PEPH.

Abstract
BACKGROUND Mucosal healing (MH) has been proposed as an essential therapeutic goal for treatment of Crohn's disease (CD) patients. The utility of serum amyloid A (SAA) for prediction of MH in CD patients is lacking. AIMS This study was conducted to evaluate the correlation of SAA with CD-related endoscopic disease activity. METHODS SAA levels in serum samples obtained from CD patients as well as endoscopic findings based on a simple endoscopic score for CD (SES-CD) were assessed in relation to CD activity index (CDAI). The diagnostic ability of MH in correlation with SAA level was evaluated using receiver operating characteristic (ROC) curve analysis. RESULTS Fifty-five patients with CD were enrolled. Mean SAA level was significantly higher in clinical and endoscopic active phases as compared to an inactive phase. SAA level was also significantly correlated with SES-CD (r = 0.64, p < 0.01) and CDAI (r = 0.42, p < 0.01). The area under the ROC curve for SAA level was 0.77 and the optimal cut-off value for SAA to predict MH was 5.9 μg/dl. SAA level was shown to be associated with MH, with a sensitivity of 68% and specificity of 83%. CONCLUSIONS SAA may be a possible biomarker for evaluating MH in CD patients.

Abstract
Background and study aims Recurrence of common bile duct stones (CBDS) in patients treated with endoscopic sphincterotomy (ES) can lead to deterioration in their quality of life. Although the pathology and related factors are unclear, we speculated that proton pump inhibiter (PPI) administration increases the risk of CBDS recurrence by altering the bacterial mixture in the bile duct. Patients and methods The primary endpoint of this retrospective study was recurrence-free period. Several independent variables considered to have a relationship with CBDS recurrence including PPI use were analyzed using a COX proportional hazard model, with potential risk factors then evaluated by propensity score matching analysis. Results A total of 219 patients were analyzed, with CBDS recurrence found in 44. Analysis of variables using a COX proportional hazard model demonstrated that use of PPIs and ursodeoxycholic acid (UDCA), as well as the presence of periampullary diverticula (PD) each had a hazard ratio (HR) value greater than 1 (HR 2.2, P = 0.007; HR 2.0, P = 0.02; HR 1.9, P = 0.07; respectively). Furthermore, propensity score matching analysis revealed that the mean recurrence-free period in the oral PPI cohort was significantly shorter as compared with the non-PPI cohort (1613 vs. 2587 days, P = 0.014). In contrast, neither UDCA administration nor PD presence was found to be a significant factor in that analysis (1557 vs. 1654 days, P = 0.508; 1169 vs. 2011 days, P = 0.121; respectively). Conclusion Our results showed that oral PPI administration is a risk factor for CBDS recurrence in patients who undergo ES.

Downregulation of serotonin reuptake transporter gene expression in healing colonic mucosa in presence of remaining low-grade inflammation in ulcerative colitis. J Gastroenterol Hepatol 2016; 31:1443-52.

Abstract
BACKGROUND AND AIM The serotonin reuptake transporter (SERT) terminates serotonin activity by removing it from interstitial space. Downregulated colonic SERT expression has been reported in irritable bowel disease (IBS), and symptoms resembling IBS occur in cases of inflammatory bowel disease (IBD) in remission; thus, a common pathogenesis for IBS and IBD is possible. However, little is known regarding SERT expression in colonic mucosa of IBD patients during healing. METHODS Twenty-two ulcerative colitis (UC) patients underwent colonoscopy examinations, during which inflamed mucosa was distinguished from that undergoing healing. Healing mucosa was classified into regular and irregular vessel patterns by narrowband imaging magnifying colonoscopy. Expressions of SERT and various inflammation-related genes in biopsy samples were assessed using a polymerase chain reaction array system and real-time polymerase chain reaction. Colitis model mice were established by administration of dextran sodium sulfate or transfer of CD4(+) T cells isolated from SAMP1 mice, then time-course changes of SERT and inflammatory gene expressions were observed in colonic mucosa. RESULTS In UC patients, SERT expression in inflamed mucosa was significantly lower than in healing mucosa. SERT expression was decreased in healing mucosa with an irregular vessel pattern with mildly increased levels of inflammatory gene expression. In mice, SERT expression was suppressed in inflamed mucosa and continuously observed with low-grade mucosal inflammation during colitis healing. CONCLUSIONS Sserotonin reuptake transporter expression is downregulated in healing colonic mucosa of UC patients and that suppression may be dependent on the presence of remaining low-grade colonic inflammation.

Outcome of self-expandable metallic stent deployment in patients with malignant gastroduodenal outlet obstruction and Niti-S and WallFlex comparison: a multicenter retrospective clinical study. J Dig Dis 2016; 17:518-525. [PMID: 27383654 DOI: 10.1111/1751-2980.12377] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/04/2016] [Revised: 06/20/2016] [Accepted: 06/30/2016] [Indexed: 12/11/2022]
Abstract
OBJECTIVES Several studies report on the outcomes of self-expandable metallic stents (SEMSs) deployment for malignant gastric outlet obstruction (GOO). However, data was mostly based on the analysis of single-center studies including only a small number of patients. This study aimed to evaluate clinical outcomes after the deployment of SEMS in patients with malignant GOO and to compare the clinical outcomes of two metallic stents with different designs. METHODS Altogether 125 consecutive patients from five institutions were included. Clinical outcomes were evaluated according to technical success, clinical success, stent patency period, survival period and complications. A comparison of clinical outcomes between Niti-S pyloric/duodenal and WallFlex duodenal stents was also undertaken. RESULTS Rates for clinical and technical success were 100% and 92.0%, respectively. The median stent patency and survival periods were 72.0 days (range 3-775 days) and 75.0 days (range 3-775 days), respectively. The rate of overall adverse events was 28.8%. The rate of stent dysfunction was 16.8%, and that of adverse events, except stent dysfunction was 12.0%. Massive bleeding occurred in two patients as a late complication. The clinical success rate for Niti-S stent was significantly higher than that for WallFlex stent (96.2% vs 84.8%, P = 0.023). CONCLUSIONS We successfully deployed a SEMS in malignant GOO. The selection of a SEMS with a lower axial force may be important for patients to resume the oral food intake. Additionally, consideration must be given to the appropriate management of fatal bleeding as a late complication.

Usefulness of computed tomography with air insufflation of the stomach prior to percutaneous endoscopic gastrostomy procedure. J Clin Biochem Nutr 2016; 58:246-50. [PMID: 27257351 PMCID: PMC4865598 DOI: 10.3164/jcbn.15-145] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2015] [Accepted: 01/05/2016] [Indexed: 12/11/2022] Open
Abstract
We examined the results of computed tomography (CT) with and without air insufflation of the stomach prior to performing percutaneous endoscopic gastrostomy (PEG). We retrospectively analyzed 366 patients who underwent PEG. CT images obtained with and without air insufflation were examined for the presence or absence of contact between the gastric anterior wall and abdominal wall. PEG outcome based on CT findings was also examined. CT with and without air insufflation was performed in 272 and 94 patients, respectively. Contact between the gastric anterior wall and abdominal wall was shown in 254 (93.4%) with and 45 (47.9%) without air insufflation, all of whom underwent a successful PEG procedure. In patients without contact between the gastric anterior wall and abdominal wall, PEG was not successful in 3 of 49 (6.1%) examined by CT without and 6 of 18 (33.3%) examined with air insufflation (p = 0.004). Values for diagnostic accuracy for contact between the gastric anterior wall and abdominal wall shown by CT with and without air insufflation in successful PEG cases were 0.96 and 0.51, respectively. In conclusion, CT with air insufflation more often revealed contact between the gastric anterior wall and abdominal wall as compared to CT without air insufflation, which may help to predict PEG procedure success.

Fecal calprotectin level correlated with both endoscopic severity and disease extent in ulcerative colitis. BMC Gastroenterol 2016; 16:47. [PMID: 27071448 PMCID: PMC4830074 DOI: 10.1186/s12876-016-0462-z] [Citation(s) in RCA: 35] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2015] [Accepted: 04/07/2016] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND The relationship between fecal calprotectin (FC) and disease extent in ulcerative colitis (UC) has not been fully elucidated. The aim of this study was to clarify the correlation of FC with disease extent and severity in UC patients. METHODS UC patients scheduled to undergo an ileocolonoscopy were enrolled and fecal samples for FC measurement were collected prior to the procedure. A Mayo endoscopic subscore (MES) was determined for each of 5 colonic segments. To evaluate the association of FC with extent of affected mucosa as well as disease severity, we assessed the correlation of FC level with the sum of MES (S-MES) for the 5 colonic segments as compared to the maximum score of MES (M-MES). RESULTS FC measurements in conjunction with findings from 136 complete colonoscopies in 102 UC patients were evaluated. FC level showed a stronger correlation with S-MES (correlation coefficient r = 0.86, p < 0.001) as compared to M-MES (r = 0.79, p < 0.001). In patients with an M-MES of 1, 2, and 3, FC level showed a significant correlation with S-MES (r = 0.67, p < 0.001; r = 0.70, p < 0.001; r = 0.47, p = 0.04, respectively). Our findings indicate that FC level is elevated in patients with greater areas of affected mucosa even in those with the same M-MES value. CONCLUSIONS FC level was shown to be correlated with the extent of affected mucosa as well as severity in UC patients, thus it is useful for precise assessment of mucosal inflammation.

Decreased Frequency of Intestinal Regulatory CD5+ B Cells in Colonic Inflammation. PLoS One 2016; 11:e0146191. [PMID: 26727001 PMCID: PMC4705109 DOI: 10.1371/journal.pone.0146191] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2015] [Accepted: 12/13/2015] [Indexed: 02/06/2023] Open
Abstract
Background CD5+ B cells are a type of regulatory immune cells, though the involvement of this B cell subset in intestinal inflammation and immune regulation is not fully understood. Methods We examined the distribution of CD5+ B cells in various mouse organs. Expression levels of CD11b, IgM, and toll-like receptor (TLR)-4 and -9 in B cells were evaluated. In vitro, TLR-stimulated IL-10 production by colonic lamina propria (LP) CD5+ and CD5- B cells was measured. In vivo, mice with acute or chronic dextran sulfate sodium (DSS)-induced colonic injury were examined, and the frequency of colonic LP CD5+ B cells in those was assessed by flow cytometry. Results The expression level of TLR9 was higher in colonic LP CD5+ B cells as compared to CD5- B cells. Colonic LP CD5+ B cells produced greater amounts of IL-10 following stimulation with TLR ligands, especially TLR9, as compared with the LP CD5- B cells. Acute intestinal inflammation transiently decreased the frequency of colonic LP CD5+ B cells, while chronic inflammation induced a persistent decrease in colonic LP CD5+ B cells and led to a CD5- B cell-dominant condition. Conclusion A persistent altered mucosal B cell population caused by chronic gut inflammation may be involved in the pathogenesis of inflammatory bowel diseases.

Abstract
A 60-year-old woman was admitted to our hospital with upper abdominal pain and jaundice. Computed tomography showed a 9-cm mass that was penetrated by the common hepatic artery in the pancreatic head area. Endoscopic retrograde pancreatography revealed no stenosis or obstruction of the main pancreatic duct, and a cytologic examination of the patient's pancreatic juice was negative. Next, endoscopic ultrasound-guided fine needle aspiration was performed. The immunohistological findings of the specimen revealed a diffuse large B-cell lymphoma. The size of the tumor was significantly reduced after 8 cycles of R-CHOP chemotherapy (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone).

Role of milk fat globule-epidermal growth factor 8 in colonic inflammation and carcinogenesis. J Gastroenterol 2015; 50:862-75. [PMID: 25596854 DOI: 10.1007/s00535-014-1036-x] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/18/2014] [Accepted: 12/24/2014] [Indexed: 02/04/2023]
Abstract
BACKGROUND Milk fat globule-epidermal growth factor 8 (MFG-E8) promotes phagocytic clearance of apoptotic cells to maintain normal tissue homeostasis. However, its functions in intestinal inflammation and carcinogenesis are unknown. METHODS Experimental colitis was induced in MFG-E8 knockout (KO) and wild-type (WT) mice by dextran sodium sulfate (DSS) administration. Colon tissues were used for assessments of colitis activity and epithelial proliferation. A mouse colitis-associated cancer (CAC) model was induced by intraperitoneal injection of azoxymethane (AOM) and then the animals were given a single administration of DSS. A sporadic colon cancer model was established by repeated intraperitoneal injections of AOM. The role of MFG-E8 in epithelial proliferation with or without treatment of siRNA targeting α(v)-integrin was examined in vitro using a WST-1 assay. RESULTS The severity of colitis in KO mice was greater than that in WT mice, while the proliferative potential of colonic epithelial cells in KO mice was lower during the regenerative phase. In both CAC and sporadic models, tumor size in KO was lower as compared to WT mice, while decreased tumor incidence was only found in the CAC model. In vitro findings showed that MFG-E8 promotes epithelial cell proliferation, and treatment with a siRNA targeting α(v)-integrin reduced the proliferation of Colon-26 cells stimulated with recombinant MFG-E8. CONCLUSIONS MFG-E8 promotes tumor growth regardless of the presence or absence of colonic inflammation, whereas colon tumor development is initiated by MFG-E8 under inflammatory conditions. These MFG-E8 functions may be dependent on integrin-mediated cellular signaling.

Abstract
A flat, elevated lesion measuring 5 mm in diameter was found in the gastric body of an 80-year-old man. A biopsy showed moderately differentiated adenocarcinoma, and endoscopic ultrasonography revealed a hypoechoic mass located in the submucosa. Endoscopic submucosal dissection was subsequently performed, and a pathological examination revealed a tumor composed of adenocarcinoma and neuroendocrine carcinoma with submucosal infiltration. The pathological diagnosis was gastric mixed adenoneuroendocrine carcinoma (MANEC). An additional gastrectomy procedure was performed, and no recurrence was noted for at least three years. This case is interesting with respect to the carcinogenesis of endocrine cell carcinoma and MANEC.

Abstract
Systemic AA amyloidosis is a complication of various inflammatory diseases including Crohn's disease (CD). Amyloid nephropathy is the most common clinical presentation of AA amyloidosis leading to renal failure, and affected patients often require hemodialysis and ultimately renal transplantation. We herein report the successful use of infliximab as maintenance therapy for amyloid nephropathy in a patient with CD. In the present patient, surgical treatment and infliximab infusion immediately induced a remission of CD, and scheduled infliximab therapy successfully maintained the patient's stable condition for three years, with a significant decrease in the serum creatinine level.

Abstract
This study aimed to assess the diagnostic usefulness of CT enterography (CTE) in Crohn's disease in Japanese patients. A total of 32 cases with bowel symptoms underwent CT enterography with polyethylene glycol electrolyte solution as oral contrast medium, among which 18 were clinically diagnosed as Crohn's disease and 14 were not: ulcerative colitis 1, Beçhet disease 1, simple ulcer 1, inflammatory bowel disease without definite diagnosis 5 and bowel symptoms of unknown origin 6. The incidence of bowel wall thickening, mural hyperenhancement, "the comb sign", mesenteric lymph nodes swelling, and stenosis were significantly higher in Crohn's disease than in other disease. Moreover, uneven bowel wall thickening and unilateral mural hyperenhancement on CTE were characteristic features of Crohn's disease, which our original quantitative evaluation with imaging analysis could support. Consequently, CTE is useful in Japanese patients with Crohn's disease.

Abstract
A 69-year old man came to our hospital complaining of abdominal pain. Contrast-enhanced computed tomography (CT) showed a 65-mm ruptured mass in Couinaud segment 5 of the liver. The mass was treated with emergent transcatheter arterial embolization (TAE), followed by partial hepatectomy. Microscopically, the mass was determined to be an angiosarcoma. Six months previously, enhanced CT had shown a 15-mm mass diagnosed as a cavernous hemangioma in the same region of the liver. Even when the enhancement pattern of a small hepatic mass resembles that of hemangioma, the mass should be reassessed within several months to exclude a diagnosis of hepatic angiosarcoma.
