    Abstract Inflammatory bowel disease is a multifactorial etiology, associated with environmental factors that can trigger both debut and relapses. A high level of tumor necrosis factor-α in the gut is the main consequence of immune system imbalance. The aim of treatment is to restore gut homeostasis. In this study, fresh blood and serum samples were used to identify biomarkers and to discriminate between Crohn's disease and ulcerative colitis patients under remission treated with anti-TNF. Metabolomics based on Nuclear Magnetic Resonance spectroscopy (NMR) was used to detect unique biomarkers for each class of patients. Blood T lymphocyte repertories were characterized, as well as cytokine and transcription factor profiling, to complement the metabolomics data. Higher levels of homoserine-methionine and isobutyrate were identified as biomarkers of Crohn's disease with ileocolic localization. For ulcerative colitis, lower levels of creatine-creatinine, proline, and tryptophan were found that reflect a deficit in the absorption of essential amino acids in the gut. T lymphocyte phenotyping and its functional profiling revealed that the overall inflammation was lower in Crohn's disease patients than in those with ulcerative colitis. These results demonstrated that NMR metabolomics could be introduced as a high-throughput evaluation method in routine clinical practice to stratify both types of patients related to their pathology. KEY MESSAGES: NMR metabolomics is a non-invasive tool that could be implemented in the normal clinical practice for IBD to assess beneficial effect of the treatment. NMR metabolomics is a useful tool for precision medicine, in order to sew a specific treatment to a specific group of patients. Finding predictors of response to IFX would be desirable to select patients affected by IBD. Immunological status of inflammations correlates with NMR metabolomics biomarkers.

    Abstract Background: Current treatment of infected pancreatic necrosis (IPN) follows a step-up approach. Our group designed a step-up protocol that associates endoscopic drainage with local infusion of antibiotics through transmural nasocystic catheter. Aim of our study was to evaluate our step-up protocol for IPN in terms of proportion of patients avoiding necrosectomy.
    Methods: Retrospective analysis of patients admitted with acute pancreatitis (AP) between January 2015 and December 2018. The number of patients who responded to each therapeutic step were analysed: step 1, systemic antibiotics; step 2, endoscopic transmural drainage and local infusion of antibiotics; step 3, endoscopic necrosectomy.
    Results: 1158 patients with AP were included. 110 patients (8.4%) suffered from necrotising pancreatitis; 48 of them had IPN (42.6% of necrotising pancreatitis) and were treated with systemic antibiotics. Nineteen patients (39.6% of IPN) responded and did not required any invasive therapy. Six patients with IPN on systemic antibiotics died within the first 4 weeks of disease before step 2 could be applied. Urgent surgical necrosectomy in the first 4 weeks was performed in three additional patients. Endoscopic drainage and local antibiotic therapy was performed in the remaining 20 patients; 9 (45% of them) did well and 9 patients underwent necrosectomy (18.7% of IPN). Two patients died on drainage. Overall mortality of the total cohort of AP was 2.53% CONCLUSIONS: Addition of local infusion of antibiotics to endoscopic drainage avoids the need of necrosectomy in half of patients with IPN not responding to systemic antibiotics.
