Anti-tumour necrosis factor-α antibodies and B cell homeostasis in human inflammatory bowel diseases

Background The expression of CD70 on T cells is greatly enhanced by antigen-presenting cell (APC)-associated signals, such as tumour necrosis factor(TNF)-α, which is constitutionally high in patients with inflammatory bowel disease (IBD). Experimentally, the chronic activation of CD27 as a result of the constitutive expression of CD70 leads to the demise of B cells in bone marrow (BM) and the secondary lymphoid organs. The aim of this study was to assess the number and phenotype of circulating B cell in untreated IBD patients and their counterparts treated with biological anti-TNF drugs. Methods The study involved 13 untreated IBD patients, 36 IBD patients treated with biological drugs, and…

Activities related to inflammatory bowel disease management during and after the coronavirus disease 2019 lockdown in Italy: How to maintain standards of care

BACKGROUND AND AIMS: Restructuring activities have been necessary during the lockdown phase of the coronavirus disease 2019 (COVID-19) pandemic. Few data are available on the post-lockdown phase in terms of health-care procedures in inflammatory bowel disease (IBD) care, and no data are available specifically from IBD units. We aimed to investigate how IBD management was restructured during the lockdown phase, the impact of the restructuring on standards of care and how Italian IBD units have managed post-lockdown activities. METHODS: A web-based online survey was conducted in two phases (April and June 2020) among the Italian Group for IBD affiliated units within the entire country. We inv…

The PROSIT Cohort of Infliximab Biosimilar in IBD: A Prolonged Follow-up on the Effectiveness and Safety Across Italy.

BACKGROUND We report a prospective, nationwide cohort evaluating the safety and effectiveness of CT-P13. METHODS A structured database was used to record serious adverse events (SAEs), clinical remission/response, inflammatory biomarkers (CRP and calprotectin), and endoscopic findings. RESULTS Eight hundred ten patients with inflammatory bowel disease (IBD) (452 Crohn's disease [CD]) were enrolled. Four hundred fifty-nine patients were naive to anti-TNFα (group A), 196 had a previous exposure (group B), and the remaining 155 were switched to CT-P13 (group C). All patients were included in the safety evaluation with a mean follow-up of 345 ± 215 days and a total number of 6501 infusions. One…
