RESUMO
INTRODUCTION: Risk factors for developing pancreatitis due to thiopurines in patients with inflammatory bowel disease (IBD) are not clearly identified. Our aim was to evaluate the predictive pharmacogenetic risk of pancreatitis in IBD patients treated with thiopurines. METHODS: We conducted an observational pharmacogenetic study of acute pancreatitis events in a cohort study of IBD patients treated with thiopurines from the prospectively maintained ENEIDA registry biobank of GETECCU. Samples were obtained and the CASR, CEL, CFTR, CDLN2, CTRC, SPINK1, CPA1, and PRSS1 genes, selected based on their known association with pancreatitis, were fully sequenced. RESULTS: Ninety-five cases and 105 controls were enrolled; a total of 57% were women. Median age at pancreatitis diagnosis was 39 years. We identified 81 benign variants (50 in cases and 67 in controls) and a total of 35 distinct rare pathogenic and unknown significance variants (10 in CEL, 21 in CFTR, 1 in CDLN2, and 3 in CPA1). None of the cases or controls carried pancreatitis-predisposing variants within the CASR, CPA1, PRSS1, and SPINK1 genes, nor a pathogenic CFTR mutation. Four different variants of unknown significance were detected in the CDLN and CPA1 genes; one of them was in the CDLN gene in a single patient with pancreatitis and 3 in the CPA1 gene in 5 controls. After the analysis of the variants detected, no significant differences were observed between cases and controls. CONCLUSION: In patients with IBD, genes known to cause pancreatitis seem not to be involved in thiopurine-related pancreatitis onset.

Therapy with anti-tumor necrosis factor (TNF) has dramatically changed the natural history of Crohn's disease (CD). However, these drugs are not without adverse events, and up to 40% of patients could lose efficacy in the long term. We aimed to identify reliable markers of response to anti-TNF drugs in patients with CD. A consecutive cohort of 113 anti-TNF naive patients with CD was stratified according to clinical response as short-term remission (STR) or non-STR (NSTR) at 12 weeks of treatment. We compared the protein expression profiles of plasma samples in a subset of patients from both groups prior to anti-TNF therapy by SWATH proteomics. We identified 18 differentially expressed proteins (p ≤ 0.01, fold change ≥ 2.4) involved in the organization of the cytoskeleton and cell junction, hemostasis/platelet function, carbohydrate metabolism, and immune response as candidate biomarkers of STR. Among them, vinculin was one of the most deregulated proteins (p < 0.001), whose differential expression was confirmed by ELISA (p = 0.054). In the multivariate analysis, plasma vinculin levels along with basal CD Activity Index, corticosteroids induction, and bowel resection were factors predicting NSTR.

Mesalazine is the most widely used aminosalicylate for induction and maintenance of remission in patients with mild-to-moderate ulcerative colitis (UC). Drug-induced hypersensitivity pneumonitis is considered very rare (<1/10.000 patients). Due to its rarity and the scarce cases reported, mesalazine-induced lung injury needs to be highly suspected in a patient with onset of respiratory symptoms and UC under treatment with salicylates. It should make the clinician formulate a differential diagnosis that includes not only infections (tuberculosis, bacterial...) or the inflammatory bowel disease itself, but also the current coronavirus disease 2019 (COVID-19) since their clinical and radiological manifestations may be very similar.

Eosinophilic esophagitis is an underdiagnosed disease that should be suspected in all patients with dysphagia and food impaction. Although these are the leading symptoms, the clinical and endoscopic spectrum is highly varied. Clinicians should be aware of the risk of endoscopy-related complications in this disorder. Precautions should be maximized in endoscopic examinations to avoid iatrogenic damage. We describe the case of a young patient with esophageal stricture and dysphagia who suffered a perforation following a biopsy.

BACKGROUND/AIMS: To determine the value of systemic cytokines as predictors of relapse in inflammatory bowel disease (IBD). METHODOLOGY: A prospective study with 135 patients in clinical remission for at least 3 months. At enrollment, a venous blood was drawn in order to measure, by an ELISA test, the following cytokines: TNFalpha, TNFalpha-R1 and R2, IL-16, IL-1beta, IL 2, IL-R2, IL-6, IL-10, and IFNgamma. All patients were followed-up for one year. RESULT: Sixty-six patients had Crohn's disease (CD) and 69 had ulcerative colitis (UC). Thirty-nine (30%) had a relapse. Forty-four percent were receiving immunomodulatory therapy. No differences were found regarding detection and baseline concentration of the various cytokines between patients with CD and UC, or between patients with or without ongoing use of immunomodulators. The detection and concentration levels of cytokines were not associated with the risk of relapse of IBD. CONCLUSIONS: Systemic cytokines are of little value to predict IBD relapse.
