Abstract

Background & Aims: Refractory celiac disease type II (RCDII) is a rare indolent lymphoma in the small intestine characterized by a clonally expanded intraepithelial intracellular CD3+surfaceCD3-CD7+CD56- aberrant cell population. However, RCDII pathogenesis is ill-defined. Here, we aimed at single-cell characterization of the innate and adaptive immune system in RCDII. Methods: Paired small intestinal and blood samples from 12 RCDII patients and 6 healthy controls were assessed by single-cell mass cytometry with a 39–cell surface marker antibody panel, designed to capture heterogeneity of the innate and adaptive immune system. A second single-cell mass cytometry panel that included transcription factors and immune checkpoints was used for analysis of paired samples from 5 RCDII patients. Single-cell RNA sequencing analysis was performed on duodenal samples from 2 RCDII patients. Finally, we developed a 40-marker imaging mass cytometry antibody panel to evaluate cell–cell interactions in duodenal biopsy specimens of RCDII patients. Results: We provide evidence for intertumoral and intratumoral cell heterogeneity within the duodenal and peripheral aberrant cell population present in RCDII. Phenotypic discrepancy was observed between peripheral and duodenal aberrant cells. In addition, we observed that part of the aberrant cell population proliferated and observed co-localization of aberrant cells with CD163+ antigen-presenting cells (APCs) in situ. In addition, we observed phenotypic discrepancy between peripheral and duodenal aberrant cells. Conclusions: Novel high-dimensional single-cell technologies show substantial intertumoral and intratumoral heterogeneity in the aberrant cell population in RCDII. This may underlie variability in refractory disease status between patients and responsiveness to therapy, pointing to the need for personalized therapy in RCDII based on patient-specific immune profiles., Pattern Recognition and Bioinformatics

Abstract

ObjectivesCounting intraepithelial lymphocytes (IEL) is central to the histological diagnosis of coeliac disease (CD), but no definitive ‘normal’ IEL range has ever been published. In this multicentre study, receiver operating characteristic (ROC) curve analysis was used to determine the optimal cut-off between normal and CD (Marsh III lesion) duodenal mucosa, based on IEL counts on >400 mucosal biopsy specimens.DesignThe study was designed at the International Meeting on Digestive Pathology, Bucharest 2015. Investigators from 19 centres, eight countries of three continents, recruited 198 patients with Marsh III histology and 203 controls and used one agreed protocol to count IEL/100 enterocytes in well-oriented duodenal biopsies. Demographic and serological data were also collected.ResultsThe mean ages of CD and control groups were 45.5 (neonate to 82) and 38.3 (2–88) years. Mean IEL count was 54±18/100 enterocytes in CD and 13±8 in normal controls (p=0.0001). ROC analysis indicated an optimal cut-off point of 25 IEL/100 enterocytes, with 99% sensitivity, 92% specificity and 99.5% area under the curve. Other cut-offs between 20 and 40 IEL were less discriminatory. Additionally, there was a sufficiently high number of biopsies to explore IEL counts across the subclassification of the Marsh III lesion.ConclusionOur ROC curve analyses demonstrate that for Marsh III lesions, a cut-off of 25 IEL/100 enterocytes optimises discrimination between normal control and CD biopsies. No differences in IEL counts were found between Marsh III a, b and c lesions. There was an indication of a continuously graded dose–response by IEL to environmental (gluten) antigenic influence.

12. Inflammatory Bowel Disease in a Patient Returning from Colombia: Association with Dipeptidyl Peptidase 4 Inhibitor?

Abstract

Introduction: Recent-onset colitis poses a diagnostic challenge, necessitating a thorough evaluation to identify potential infectious and non-infectious etiologies. We considered inflammatory bowel disease (IBD) secondary to dipeptidyl peptidase 4 (DPP-4) inhibitor-induced colitis., Case Presentation: This case report details the presentation and management of a patient with persistent dysentery, refractory to conventional treatments, ultimately attributed to IBD possibly secondary to long-term DPP-4 inhibitor use. Following an episode of suspected amebiasis, the patient experienced prolonged bloody diarrhea with an endoscopic image compatible with ulcerative colitis. Extensive infectious diagnostics were negative. Ultimately, the cessation of sitagliptin therapy resulted in rapid symptom resolution and normalization of eosinophilia, as well as endoscopic improvement. However, after a few weeks, the patient was readmitted with diarrhea after continued cessation of sitagliptin., Conclusion: This case underscores the importance of considering IBD secondary to DPP-4 inhibitor use in the evaluation of patients with recent-onset IBD. Further research is needed to elucidate the pathophysiological mechanisms underlying the relationship between DPP-4 inhibitors and IBD., Competing Interests: The authors have no conflicts of interest to declare., (© 2025 The Author(s).
