  Abstract A 67‐year‐old man visited our hospital complaining of dark‐colored urine and upper abdominal pain. Magnetic resonance cholangiopancreatography showed stricture of the distal bile duct, and contrast‐enhanced computed tomography showed irregular thickening of the distal bile duct wall. However, no enlarged lymph nodes, pancreatic tumors, or other neoplastic lesions were apparent around the bile duct. Endoscopic ultrasonography and intraductal ultrasonography showed irregular thickening of the inner hypoechoic layer without the disappearance of the innermost thin hyperechoic layer. On the basis of these findings, we considered that the bile duct lesion was of non‐epithelial origin. Thus, we repeatedly performed bile duct biopsies from the same site under fluoroscopy to obtain a sample of the submucosal tissue. The pathological diagnosis was diffuse large B‐cell lymphoma, and the patient received systemic chemotherapy (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone). After six courses of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone, positron emission tomography‐computed tomography showed the disappearance of 18‐fluorodeoxyglucose uptake in the bile duct and endoscopic retrograde cholangiography showed improvement of the bile duct stricture. Endoscopic findings and repeated biopsies were useful in making the diagnosis of primary biliary diffuse large B‐cell lymphoma.

  　View Summary

  BACKGROUND AND AIM: Recently, noninvasive fecal markers have been used as indicators of intestinal inflammation in patients with inflammatory bowel disease (IBD). We conducted a clinical validation study to measure fecal calprotectin (Cp), lactoferrin (Lf), and hemoglobin (Hb) levels using an all-in-one kit in patients with IBD and colorectal tumors and aimed to clarify the utility of these fecal markers. METHODS: In this study, 104 patients were analyzed, including 25 patients with ulcerative colitis (UC), 20 with Crohn's disease (CD), 48 with colorectal tumors, and 13 healthy controls (HC). Of the 48 patients with colorectal tumors, 14 had invasive cancer. We validated the utility of fecal Cp, Lf, and Hb levels by simultaneously measuring fecal markers in patients with IBD and colorectal tumors. RESULTS: Fecal Cp and Lf had almost equivalent abilities in detecting clinical remission in patients with UC; however, fecal Cp was slightly superior to Lf. Regarding colorectal tumors, fecal Cp and Lf levels tended to be higher in patients with adenomas and colorectal cancer than in HCs. Although fecal Hb alone had the best sensitivity and specificity for detecting colorectal cancer, it had relatively low sensitivity for detecting advanced neoplasms and colorectal cancer. CONCLUSION: Fecal Cp and Lf can be used as almost equivalent biomarkers to assess the clinical activity in patients with UC. Fecal Hb is the most useful marker for screening colorectal cancer; however, adding fecal Cp and Lf may compensate for the low sensitivity of detecting for advanced colorectal tumors based on Hb alone.

  　View Summary

  The relevance of endoscopic monitoring of ulcerative colitis (UC) has been translated into the new concept of “mucosal healing (MH)” as the therapeutic goal to achieve because a large amount of scientific data have revealed the favorable prognostic value of a healed mucosa in determining the clinical outcome of UC. Recent interest in MH has skewed toward not only endoscopic remission but also histological improvement (so called histological MH). However, we should recognize that there have been no prospectively validated endoscopic scoring systems of UC activity in previous clinical trials. Artificial intelligence (AI)-assisted endoscopy has been developed for gastrointestinal cancer surveillance. Recently, several AI-assisted endoscopic systems have been developed for assessment of MH in UC. In the future, the development of a new endoscopic scoring system based on AI might standardize the definition of MH. Therefore, “The road to an exact definition of MH in the treatment of UC has begun only now”.

  本邦におけるクローン病 (Crohn’s disease: CD) 患者数は増加の一途をたどっているが，疾患の原因は未だ明らかとなっておらず，根治的な治療法は存在しない．申請者の研究室ではこれまでに，大腸上皮における低分子量GTP蛋白質Ralの活性化が，NLRP3 inflammasome を介した大腸炎及び炎症性大腸発癌 (colitis-associated cancer: CAC) に極めて重要であることを報告してきた．さらに，申請者が行った予備検討で，小腸炎症においてもRalの活性化が確認されていることから，RalがCDの小腸病変とも関連している可能性が高いと考えた．一方，CD発症の原因の一つとして腸管免疫機構の破綻が考えられており，中でも小腸粘膜免疫におけるPaneth 細胞の役割が注目されている．本研究では，Ral活性化のPaneth細胞機能における役割を解析することにより，CDの病態解明に取り組む．

  　View Summary

  The human small intestine is the key organ for absorption, metabolism, and excretion of orally administered drugs. To preclinically predict these reactions in drug discovery research, a cell model that can precisely recapitulate the in vivo human intestinal monolayer is desired. Here, we developed a monolayer platform using human biopsy-derived duodenal organoids for application to pharmacokinetic studies. The human duodenal organoid-derived monolayer was prepared by a simple method in 3 to 8 days. It consisted of polarized absorptive cells and had tight junctions. It showed much higher cytochrome P450 (CYP) 3A4 and carboxylesterase (CES) 2 activities than the existing models (Caco-2 cells). It also showed efflux activity of P-glycoprotein (P-gp) and inducibility of CYP3A4. This monolayer assay system can be a general platform for a wide range of applications including pharmaceutical research.
