Abstract
Introduction Eosinophilic esophagitis (EoE) is a chronic, inflammatory, antigen-driven disease of the esophagus. Tissue EoE pathology has previously been extensively characterized by novel transcriptomics and proteomic platforms, however the majority of surface marker determination and screening has been performed in blood due to mucosal tissue size limitations. While eosinophils, CD4+ T cells, mast cells and natural killer (NK) T cells were previously investigated in the context of EoE, an accurate picture of the composition of peripheral blood mononuclear cells (PBMC) and their activation is missing. Methods In this study, we aimed to comprehensively analyze the composition of peripheral blood mononuclear cells and their activation using surface marker measurements with multicolor flow cytometry simultaneously in both blood and mucosal tissue of patients with active EoE, inactive EoE, patients with gastroesophageal reflux disease (GERD) and controls. Moreover, we set out to validate our data in co-cultures of PBMC with human primary esophageal epithelial cells and in a novel inducible mouse model of eosinophilic esophagitis, characterized by extensive IL-33 secretion in the esophagus. Results Our results indicate that specific PBMC populations are enriched, and that they alter their surface expression of activation markers in mucosal tissue of active EoE. In particular, we observed upregulation of the immunomodulatory molecule CD38 on CD4+ T cells and on myeloid cells in biopsies of active EoE. Moreover, we observed significant upregulation of PD-1 on CD4+ and myeloid cells, which was even more prominent after corticosteroid treatment. With co-culture experiments we could demonstrate that direct cell contact is needed for PD-1 upregulation on CD4+ T cells. Finally, we validated our findings of PD-1 and CD38 upregulation in an inducible mouse model of EoE. Discussion Herein we show significant alterations in the PBMC activation profile of patients with active EoE in comparison to inactive EoE, GERD and controls, which could have potential implications for treatment. To our knowledge, this study is the first of its kind expanding the multi-color flow cytometry approach in different patient groups using in vitro and in vivo translational models.

Abstract
BACKGROUND Among patients with ulcerative colitis, 30-50% receive corticosteroids within the first five years after diagnosis. We aimed to reconsider their effectiveness in the context of the biologic era. METHODS In this prospective, multicenter study, patients with active ulcerative colitis (Lichtiger score ≥ 4) were eligible if initiating systemic corticosteroids. The primary endpoint was clinical response (decrease in the Lichtiger score of ≥50%) at week 4. Secondary endpoints included combined response defined as clinical response and any reduction in elevated biomarkers (CRP and/or calprotectin). Steroid dependence was assessed after three months. RESULTS A total of 103 patients were included. Clinical response was achieved by 73% of patients, and combined response by 68%. A total of 15% of patients were steroid-dependent. Activity of colitis did not influence short-term response to treatment but increased the risk for steroid dependence. Biologic-naïve patients responded better than biologic-experienced patients. Past smoking history (OR 5.38 [1.71, 20.1], p = 0.003), hemoglobin levels (OR 0.76 [0.57, 0.99] for higher levels, p = 0.045), and biologic experience (OR 3.30 [1.08, 10.6], p = 0.036) were independently associated with nonresponse. CONCLUSION Disease activity was not associated with short-term response to systemic corticosteroids but was associated with steroid dependence in patients with active ulcerative colitis. Exposure to biologics negatively affects response rates.

Abstract
BACKGROUND AND AIMS Immunological treatment failure of anti-TNF therapy negatively influences treatment persistence of a second anti-TNF in IBD patients. So far it is unknown if this effect is also observed for other monoclonal antibodies. We assessed the influence of immunogenicity to anti-TNFs on treatment persistence of subsequent ustekinumab and vedolizumab therapy. METHODS IBD patients with and without immunogenicity to anti-TNFs (undetectable trough levels and antibody titers ≥20 ng/mL) and subsequent ustekinumab (UST) and/or vedolizumab (VDZ) therapy were included in this retrospective, single-center study. The Kaplan-Meier method with the log-rank test and Cox proportional hazards were used as statistical methods. RESULTS One hundred patients (Crohn's disease: 62, Ulcerative colitis: 31, IBD unclassified: 7) with 127 treatment lines (62 with UST, 65 with VDZ) were included in the analysis. Immunogenicity to previous anti-TNFs did not influence treatment persistence of subsequent ustekinumab and vedolizumab therapy (UST: Log rank: p = .95, Immunogenicity: HR for treatment discontinuation: 0.97 [95% CI 0.31-3.04]; VDZ: p = .65, HR: 0.85 [0.41-1.75]; total cohort [UST and VDZ]: p = .62, HR: 0.86 [0.47-1.57]). Azathioprine co-treatment did not lengthen treatment persistence (UST: Log rank: p = .77, azathioprine: HR: 1.20 [0.34-4.27]; VDZ: p = .92, HR: 0.58 [0.17-1.99]; total cohort: p = .79, HR: 1.10 [0.55-2.20]). In this anti-TNF experienced cohort, patients with ustekinumab remained longer on treatment than patients receiving vedolizumab (Log rank: p = .005, UST: HR: 0.43 [0.23-0.79]). CONCLUSIONS Immunogenicity to anti-TNFs does not influence treatment persistence of subsequent ustekinumab and vedolizumab therapy.

Abstract
We report a case of acute onset of a biliary pancreatitis with cholangitis presented in our emergency department. The patient was under anticoagulant therapy with dabigatran due to persistent atrial fibrillation. Pancreatic enzymes including lipase were elevated above the linear measuring range and bilirubin together with cholestasis enzymes was also highly elevated. An ERCP with papillotomy was urgently indicated because postponing could lead to further deterioration of the patient's condition. Coagulation testing showed a prolonged thrombin time above 160sec which was followed by a diluted thrombin time (Haemoclot Test) resulted in a peak-level of dabigatran thus confirming full anticoagulation. Therefore, idarucizumab (Praxbind®) was administered pre-procedural of ERCP, the patient underwent uneventful ERCP without any bleeding complications, a full recovery was achieved and the patient was scheduled for elective cholecystectomy.
