γδ cells and tumor microenvironment: A helpful or a dangerous liason?

2017

Abstract γδ T cells are a subset of T lymphocytes that have been implicated in immunosurveillance against infections and tumors. γδ T cells are endowed with antitumor activities, and hence several γδ T cell-based small-scale clinical trials have been conducted either by in vivo activation by intravenous administration of aminobiphosphonates or by adoptive transfer of in vitro expanded γδ T cells. Although both these strategies have yielded promising results, there are a number of limitations associated with each of them which, if overcome may help to further improve efficacy. One of the most important limits is the possible polarization of tumor-infiltrating γδ T cells toward different γδ T…

Characterization of γδ T cells in intestinal mucosa from patients with early onset or long standing inflammatory bowel disease and their correlation …

2019

Abstract Background and Aims Inflammatory bowel disease [IBD] is a complex chronic inflammatory disease of the human gut with no clear aetiology. Traditionally, dysregulated adaptive immune responses play an important role even though accumulating evidence suggests a role also for innate immunity. Because of the well-known plasticity of γδ T cells, we investigated their percentage occurrence, phenotypic features and effector functions in the intestinal mucosa of early-onset and long-standing IBD patients, as compared to healthy subjects. Methods Fresh biopsies from 30 Crohn’s disease and ulcerative colitis patients were obtained and digested, and cells were analysed by flow cytometry. Resul…

2018

Abstract Background Adalimumab and golimumab are effective in the treatment of moderate to severe ulcerative colitis. Aims We reported the comparative effectiveness of adalimumab and golimumab in ulcerative colitis. Methods 118 patients treated with adalimumab and 79 treated with golimumab were included and evaluated at 8 weeks and at the end of follow up. Results Overall clinical benefit was 72.6% at 8 weeks and 58.9% at the end of follow up. Patients with longer disease duration and those treated with adalimumab had a better outcome. Clinical benefit was 78.8% in adalimumab patients and 63.3% in golimumab patients (p = 0.026) after 8 weeks; it was 66.9% in adalimumab patients and 46.8% in…

Persistence on Anti-Tumour Necrosis Factor Therapy in Older Patients with Inflammatory Bowel Disease Compared with Younger Patients: Data from the Si…

2020

BACKGROUND AND OBJECTIVE: Older people with inflammatory bowel disease (IBD) appear to have a lower response to anti-tumour necrosis factor (TNF) therapy, with more frequent complications than younger patients. The objective of this study was to assess persistence on therapy and the safety of anti-TNF therapy in older patients (aged ≥ 60 years). METHODS: We retrospectively reviewed the database of the Sicilian Network for Inflammatory Bowel Diseases (SN-IBD), extracting data regarding IBD patients aged ≥ 60 years and controls < 60 years of age at their first course of anti-TNF treatment. Data concerning persistence on therapy over the first year of treatment (primary objective) together …

Six year adalimumab efficacy in steroid-dependent Crohn's disease patients: A prospective single-center real life study.

2016

Abstract Background Adalimumab is effective in the treatment of Crohn's disease. We have already reported data on the efficacy of adalimumab in 110 steroid-dependent patients. At the end of the study 90 patients (64.5%) maintained clinical remission. Aims To assess efficacy and safety of adalimumab after 6 years in patients of the original cohort who responded to treatment. Methods The present study is an extension of the published paper on 90/110 patients. We report results on clinical remission and safety of 6 year maintenance therapy with adalimumab. Results Of the original cohort 90 patients completed the study, 17 were lost to follow-up and 3 died. At the end of follow-up (74.16 ± 10.3…

Adalimumab in steroid-dependent Crohn's disease patients: prognostic factors for clinical benefit.

2012

Background: Corticosteroids are effective in the treatment of Crohn's disease but some patients relapse during tapering or after discontinuation. We report data on efficacy and prognostic factors of response of adalimumab in steroid-dependent patients. Methods: In all, 110 steroid-dependent patients were treated with adalimumab (80/40 or 160/80 mg every other week followed by 40 mg every other week). Clinical remission was defined as steroid discontinuation without symptomatic recurrence and clinical response as the reduction or maintenance of the initial Crohn's Disease Activity Index (CDAI) value reducing steroid dosage but without its discontinuation at week 6 and at the end of follow-up…

2019

Background and aims There is an unmet need to better understand the effectiveness of different biologics in inflammatory bowel diseases. We aimed at performing a multicentre, real-life comparison of the effectiveness of infliximab [IFX] and adalimumab [ADA] in Crohn's disease [CD]. Methods Data of consecutive patients with CD treated with IFX and ADA from January 2013 to May 2017 were extracted from the cohort of the Sicilian Network for Inflammatory Bowel Disease. We used propensity score-matching accounting for the main baseline characteristics in TNF-α inhibitor-naive and non-naive patients. Results A total of 632 patients [735 total treatments] were included. Among naive patients, a cli…

Analysis of colon-infiltrating γδ T cells in chronic inflammatory bowel disease and in colitis-associated cancer

2019

Abstract Inflammatory bowel disease (IBD) remains a global health problem with a significant percentage of patients progressing to chronic inflammation and colitis-associated cancer (CAC). Whether or not γδ T cells contribute to initiation and maintenance of inflammation in IBD and in the development of CAC is not known. We have evaluated the frequency, phenotype, and functions of γδ T cells among tissue-infiltrating lymphocytes in healthy donors and IBD and CAC patients. Results show that Vδ1 T cells are the dominant γδ T-cell population in healthy tissue, whereas Vδ2 T significantly abound in chronic IBD. Vδ2 T cells produce more IFN-γ, TNF-α, and IL-17 than Vδ1 T cells in chronic inflame…

Blood-based prognostic biomarkers in Crohn’s Disease patients on biologics: a promising tool to predict endoscopic outcomes

2021

There is a growing need for biomarkers to predict therapeutic outcome in Crohn's disease (CD).The aim was to evaluate whether NLR (neutrophil-to-lymphocyte ratio), PLR (platelet-to-lymphocyte ratio), ELR (eosinophil-to-lymphocyte ratio), and ENLR (eosinophil*neutrophil-to-lymphocyte ratio), could be prognostic biomarkers of endoscopic response (ER) when starting biologics.Patients with CD who started biologics were enrolled. Multivariate analysis was used to evaluate whether NLR, PLR, ELR and ENLR at baseline and at w12 could predict ER (Simple Endoscopic Score for Crohn's disease [SES-CD] ≤2 or SES-CD≤2 and Rutgeerts i0-i1) after 52 weeks of treatment. Area under the curve (AUC) was calcul…

Impact of biliary stents on the diagnostic accuracy of EUS-guided fine-needle biopsy of solid pancreatic head lesions: A multicenter study

2021

Background and Objectives: There is no clear evidence of a negative impact of biliary stents on the diagnostic yield of EUS-guided fine-needle biopsy (EUS-FNB) for diagnosing pancreatic head lesions. We aimed to evaluate the association between the presence of biliary stents and the diagnostic accuracy of EUS-FNB. Materials and Methods: A multicenter retrospective study including all jaundiced patients secondary to pancreatic head masses was performed. Patients were divided into two groups according to the presence of a biliary stent placed before EUS-FNB. Pathological results were classified according to the Papanicolaou classification and compared against the final diagnosis. Diagnostic m…
