Background:Autoimmune pancreatitis(AIP)is a well-recognized fibroinflammatory disease of the *** the significant number of studies published on AIP type 1 and 2,no studies have been focused on AIP type not otherwise specified(NOS)and therefore very little is known about clinical features and long-term outcomes of these *** aim of this study was to investigate clinical and radiological features of AIP type ***:Patients classified as AIP type NOS at clinical onset included in our database prospectively maintained since 1995 were ***,clinical data were collected and ***:Forty-six patients were included in the *** clinical onset was mainly characterized by weight loss,jaundice and acute *** patients(17.4%)were reclassified as AIP type 2 during follow-up because of the development of ulcerative *** patients(15.2%)experienced relapse after steroid treatment but only one(2.2%)needed immunosuppressive drugs because of recurrent ***:AIP type NOS shares clinical features similar to AIP type 2 and a relevant proportion of patients was reclassified as AIP type 2 during follow-up because of the development of ulcerative *** risk of relapse is low but not irrelevant.

AIM To investigate by immunostaining glucose transporter expression in human colorectal mucosa in controls and patients with inflammatory bowel disease(IBD). METHODS Colorectal samples were obtained from patients undergoing lower endoscopic colonoscopy or rectosigmoidoscopy. Patients diagnosed with ulcerativecolitis(n = 18) or Crohn's disease(n = 10) and scheduled for diagnostic colonoscopy were enrolled. Patients who underwent colonoscopy for prevention screening of colorectal cancer or were followed-up after polypectomy or had a history of lower gastrointestinal symptoms were designated as the control group(CTRL, n = 16). Inflammatory status of the mucosa at the sampling site was evaluated histologically and/or endoscopically. A total of 147 biopsies of colorectal mucosa were collected and processed for immunohistochemistry analysis. The expression of GLUT2, SGLT1, and GLUT5 glucose transporters was investigated using immunoperoxidase labeling. To compare immunoreactivity of GLUT5 and LYVE-1, which is a marker for lymphatic vessel endothelium, doublelabeled confocal microscopy was used. RESULTS Immunohistochemical analysis revealed that GLUT2, SGLT1, and GLUT5 were expressed only in short epithelial portions of the large intestinal mucosa. No important differences were observed in glucose transporter expression between the samples obtained from the different portions of the colorectal tract and between the different patient groups. Unexpectedly, GLUT5 expression was also identified in vessels, mainly concentrated in specific areas where the vessels were clustered. Immunostaining with LYVE-1 and GLUT5 antibodies revealed that GLUT5-immunoreactive(-IR) clusters of vessels were concentrated in areas internal to those that were LYVE-1 positive. GLUT5 and LYVE-1 did not appear to be colocalized but rather showed a close topographical relationship on the endothelium. Based on their LYVE-1 expression, GLUT5-IR vessels were identified as lymphatic. Both inflamed and nonin
