: Vitamin D (VD) has immunoregulatory properties, generating interest in its potential to influence therapeutic outcomes in inflammatory bowel disease (IBD), other than affecting the expression of genes encoding enzymes and transporters involved in drug metabolism and transport. This study investigated VD-related single nucleotide polymorphisms (SNPs) as predictors of clinical responses in patients with Crohn's disease (CD) and ulcerative colitis (UC) treated with vedolizumab (VDZ) or ustekinumab (UST) after 3 (T3) and 12 months (T12), as well as the achievement of fecal calprotectin (FC) levels < 250 mg/kg, a marker of mucosal healing. : In this prospective study, 103 patients (67 CD, 36 UC) were enrolled, 40 receiving VDZ and 63 receiving UST.

Article Synopsis
  • Researchers are looking for new biomarkers to predict how Crohn's disease patients respond to anti-TNF-α treatments, as many don't improve or lose effectiveness over time.
  • In a study with 37 patients from a hospital in Italy, blood samples were analyzed to compare levels of specific microRNAs between those who responded to treatment and those who didn't.
  • The findings suggest that lower levels of let-7e and miR-126 in blood samples could indicate a higher likelihood of clinical remission for patients receiving anti-TNF-α therapy.

Background: Inflammatory bowel disease (IBD) is a group of chronic multifactorial inflammatory disorders including two major entities: Crohn's disease (CD) and ulcerative colitis (UC). Preliminary evidence suggests that patients with IBD may be at increased risk of developing intestinal and extraintestinal cancers (EICs). Actually, little is known about the association between IBD and EICs, and there is ever-growing concern regarding the safety of immunomodulators and biological therapy, which may represent a risk factor for carcinogenesis.

The burden of Inflammatory Bowel Disease (IBD) is increasing worldwide, with a particular increase in the prevalence in the elderly population, due to the ageing of young-onset IBD as well as to the increasing incidence in elderly patients. Elderly IBD patients present specific challenges to the treating physician, as they have comorbidities, lower functional reserves, and higher risk of treatment-related complications. The diagnosis of IBD in the elderly may be difficult due to a more subtle disease presentation and to a wide range of differential diagnosis.

Background And Purpose: Changes in gut microbiota composition, enteric inflammation, impairments of the intestinal epithelial barrier and neuroplastic changes in the enteric nervous system have been reported in Parkinson's disease (PD) patients and could contribute to the onset of both neurological and gastrointestinal symptoms. However, their mutual interplay has rarely been investigated. This study evaluated, in an integrated manner, changes in faecal microbiota composition, morphofunctional alterations of colonic mucosal barrier and changes of inflammatory markers in blood and stools of PD patients.

Background: Vedolizumab registration trials were the first to include elderly patients with moderate-to-severe ulcerative colitis (UC) or Crohn's disease (CD), but few real-life data have been reported in this population.

Aims: We investigated the effectiveness and safety of vedolizumab in matched cohorts of elderly and nonelderly UC and CD patients.

Methods: The Long-term Italian Vedolizumab Effectiveness (LIVE) study is a retrospective-prospective study including UC and CD patients who started vedolizumab from April 2016 to June 2017.

Background: Hereditary colorectal cancer syndromes [HCCS] are rare polyposis or nonpolyposis syndromes with a higher risk of developing colorectal cancer [CRC]. Coexisting inflammatory bowel disease [IBD], including ulcerative colitis [UC] and Crohn's disease [CD], with HCCS is exceedingly rare and presumably increases the risk of early-onset CRC.

Methods: This was a multicentre case series performed as a part of the European Crohn's and Colitis Organisation [ECCO] Collaborative Network of Exceptionally Rare case reports [CONFER] project.

Article Synopsis
  • Oncostatin M is a helpful blood marker that can show how well certain medicines work for people with inflammatory bowel diseases (IBD), especially when using anti-TNF drugs like infliximab.
  • The study looked at two groups of IBD patients to see how well their treatment worked after 54 weeks, measuring oncostatin M and other markers in their blood and stool.
  • Results showed that lower levels of oncostatin M before treatment were linked to better healing in patients taking anti-TNF drugs, but not in those on vedolizumab, indicating that oncostatin M is useful for predicting treatment success with anti-TNF medications.

The pharmacological blockade of P2X4 receptors has shown potential benefits in the management of several immune/inflammatory diseases. However, data regarding the involvement of P2X4 receptors in the pathophysiological mechanisms of action in intestinal inflammation are not well defined. We aimed to evaluate the anti-inflammatory effects of two novel and selective P2X4 receptor antagonists, NC-2600 and NP-1815-PX, and characterize the molecular mechanisms of their action in a murine model of 2,4-dinitrobenzene sulfonic acid (DNBS)-induced colitis.

Article Synopsis
  • Therapeutic drug monitoring plays a crucial role in managing inflammatory bowel disease (IBD) patients receiving anti-TNF treatments, and this study evaluates a point-of-care (POC) method to improve clinical decision-making.
  • The study involved 46 Crohn's disease patients, comparing drug trough levels using both POC and a standard homogeneous mobility shift assay (HMSA) at multiple time points to assess their effectiveness in distinguishing between remission and relapse phases.
  • Results indicated that both POC and HMSA tests reliably identified remission versus relapse, with strong correlation between the two methods, suggesting that the choice of method should hinge on factors like accessibility and physician expertise rather than accuracy.
