Anemia is one of the most frequent extra-intestinal manifestations of inflammatory bowel disease. Insidious onset, variability of symptoms and lack of standardized screening practices may increase the risk of underestimating its burden in children with IBD. Despite its relevance and peculiarity in everyday clinical practice, this topic is only dealt with in a few documents specifically for the pediatric field. The aim of the current guidelines is therefore to provide pediatric gastroenterologists with a practical update to support the clinical and therapeutic management of children with IBD and anemia. A panel of 19 pediatric gastroenterologists and 1 pediatric hematologist with experience in the field of pediatric IBD was agreed by IBD Working group of the Italian Society of Gastroenterology, Hepatology and Nutrition (SIGENP) to produce the present article outlining practical clinical approaches to the pediatric patient with IBD and anemia. The levels of evidence and recommendations have been defined for each part of the statement according to the GRADE system., Competing Interests: Declaration of competing interest The authors have no conflict of interests to declare with regards to this manuscript., (Copyright © 2024 Editrice Gastroenterologica Italiana S.r.l.

Anti-tumor necrosis factor alpha (anti-TNFα) inhibitors are used extensively for the management of moderate to severe inflammatory bowel disease (IBD) in both adult and pediatric patients. Unfortunately, not all patients show an optimal response to induction therapy, while others lose their response over time for reasons yet poorly understood. We report on a pharmacokinetic/pharmacogenetic approach to monitor the therapy with anti-TNFα in a real-world cohort of seventy-nine pediatric patients affected by IBD that was analyzed retrospectively. We evaluated plasma concentrations of infliximab, adalimumab, and related anti-drug antibodies (ADAs), and single nucleotide polymorphisms (SNPs) in genes involved in immune processes and inflammation on the anti-TNFα response. We found a significant association between the SNP in TNFα promoter (-308G>A) and clinical remission without steroids in patients on infliximab therapy. Additionally, a potential connection between HLA-DQA1*05 genetic variant carriers and a higher risk of anti-TNFα immunogenicity emerged., (© 2023.

Background: During Coronavirus Disease 2019 (COVID-19) outbreak in Lombardia, people were recommended to avoid visiting emergency departments and attending routine clinic visits. In this context, it was necessary to understand the psychological reactions of patients with chronic diseases. We evaluated the psychological effects on patients with chronic respiratory conditions and inflammatory bowel disease (IBD) through the analysis of their spontaneous contacts with their referral centres., Methods: Cross-sectional study was conducted from February 23 to April 27, 2020 in patients, or their parents, who contacted their multidisciplinary teams (MDT). E-mails and phone calls directed to the MDT of the centre for cystic fibrosis (CF) in Milano and for paediatric IBD in Bergamo, were categorised according to their contents as information on routine disease management, updates on the patient's health status, COVID-19 news monitoring, empathy towards health professionals, positive feedback and concern of contagion during the emergency., Results: One thousand eight hundred and sixteen contacts were collected during the study period. In Milano, where the majority of patients were affected by CF, 88.7% contacted health professionals by e-mail, with paediatricians receiving the largest volume of emails and phone calls compared with other professionals (P< .001). Compared with Milano, the centre for IBD in Bergamo recorded more expression of empathy towards health professionals and thanks for their activity in the COVID-19 emergency (52.4% vs 12.7%, P< .001), as well as positive feedback (64.3% vs 2.7%, P = .003)., Conclusion: One of the most important lessons we can learn from COVID-19 is that it is not the trauma itself that can cause psychological consequences but rather the level of balance, or imbalance, between fragility and resources. To feel safe, people need to be able to count on the help of those who represent a bulwark against the threat. This is the role played, even remotely, by health professionals., (© 2021 John Wiley & Sons Ltd.)

While considerable progress has been made in the treatment of inflammatory bowel diseases (IBD), alternative options are constantly sought by adult patients as well as frustrated parents of young patients. These include dietary modifications, food supplements, and, more recently, probiotics.Their potential use is based on the demonstrated role of the altered mucosal immune response to bacterial agents that eventually leads to the chronic intestinal inflammation that characterized IBD. In fact, probiotics might conceivably be beneficial due to multiple mechanisms: stimulation of anti-inflammatory cytokines, inhibition of inflammatory cytokines, strengthening of intestinal barrier, and antagonistic action on pathogens. Such mechanisms have been largely extensively investigated in animal models both in vitro and in vivo.Despite such premise, a relatively scarce number of clinical trials are available, and of them only a handful in pediatric age. Overall, available evidence is very disappointing in the treatment of Crohn's disease (CD), where no recommendation for probiotic use can be made. In ulcerative colitis (UC), on the other hand, there is clinical evidence of efficacy for some specific strains and especially for multi-strain preparations.In summary, more data are needed very likely to yield a better understanding on what strains and in what doses should be used in different specific clinical settings.
