RESUMEN
BACKGROUND: Cancer patients treated with immune check point inhibitors are at risk of developing severe colitis. However, the efficacy and safety of treatment of severe colitis is poorly understood. AIMS: To explore the safety and efficacy of infliximab and corticosteroids in severe immune-mediated enterocolitis (IMC) METHOD: We performed a nationwide retrospective cohort study on 140 cancer patients treated with infliximab due to IMC in Denmark from 2011 to 2021. RESULTS: The rate of complete remission with infliximab was 52% after one dose, increasing to 73% after two or more doses. Thirteen patients (10%) required additional treatment with vedolizumab. Patients were heavily exposed to corticosteroids and received a median accumulated dose of 3978 mg (interquartile range [IQR] 2552-6414). Age- and cancer-adjusted Cox regression analysis found that a high dose of prednisolone at start of tapering ≥75 mg/day was associated with increased mortality (HR 1.67, 1.04-2.69, p = 0.035). Patients responding to infliximab experienced an improvement of symptoms after 3 days (IQR 2-4) and complete remission after 31 days (IQR 14-61). Twenty-four percent required hospitalisation for infection during treatment for IMC, lasting 7 days (median). Secondary gastrointestinal infections occurred in 16%, with Clostridioides difficile being most common (64%). Further, 10% had a thromboembolic event during the first 90 days after infliximab treatment. CONCLUSIONS: Infliximab led to complete resolution of symptoms in 73% of patients with IMC. High prednisolone dose at tapering was associated with increased mortality rate and a high incidence of infections and hospitalisations in patients with severe IMC. We suggest optimised infliximab treatment before escalation of steroid doses.

BACKGROUND : Motorized spiral enteroscopy (MSE) has been shown to be safe and effective for deep enteroscopy in studies performed at expert centers with limited numbers of patients without previous abdominal surgery. This study aimed to investigate the safety, efficacy, and learning curve associated with MSE in a real-life scenario, with the inclusion of patients after abdominal surgery and with altered anatomy. METHODS : Patients with indications for deep enteroscopy were enrolled in a prospective observational multicenter study. The primary objective was the serious adverse event (SAE) rate; secondary objectives were the diagnostic and therapeutic yield, procedural success, time, and insertion depth. Data analysis was subdivided into training and core (post-training) study phases at centers with different levels of MSE experience. RESULTS : 298 patients (120 women; median age 68, range 19-92) were enrolled. In the post-training phase, 21.5â% (nâ=â54) had previous abdominal surgery, 10.0â% (nâ=â25) had surgically altered anatomy. Overall, SAEs occurred in 2.3â% (7/298; 95â%CI 0.9â%-4.8â%). The SAE rate was 2.0â% (5/251) in the core group and 4.3â% (2/47) in the training group, and was not increased after abdominal surgery (1.9â%). Total enteroscopy was achieved in half of the patients (nâ=â42) undergoing planned total enteroscopy. In 295/337 procedures (87.5â%), the anatomical region of interest could be reached. CONCLUSIONS : This prospective multicenter study showed that MSE was feasible and safe in a large cohort of patients in a real-life setting, after a short learning curve. MSE was shown to be feasible in postsurgical patients, including those with altered anatomy, without an increase in the SAE rate.

BACKGROUND: Whether infliximab therapy can be successfully discontinued after patients with Crohn's disease have attained sustained, clinical, biochemical, and endoscopic remission is unknown. METHODS: We conducted a multicenter, randomized, double-blind, placebo-controlled withdrawal study of infliximab in patients with Crohn's disease who were in clinical, biochemical, and endoscopic remission after standard infliximab maintenance therapy for at least 1 year. Patients were randomly assigned 1:1 to continue infliximab therapy or to receive matching placebo for 48 weeks. The primary end point was time to relapse. RESULTS: This study randomly assigned 115 patients to either the infliximab-continuation group or to the infliximab-discontinuation group. No relapses were observed among the 59 patients continuing infliximab, whereas 23 of 56 patients discontinuing infliximab experienced relapse. Time to relapse was significantly shorter among patients who discontinued infliximab than among those who continued infliximab (hazard ratio, 0.080; 95% confidence interval [CI], 0.035 to 0.186; P<0.001). At the end of the trial at week 48, relapse-free survival was 100% in the infliximab-continuation group and 51% in the infliximab-discontinuation group. The key secondary end point, time to loss of remission, was significantly shorter among patients discontinuing infliximab therapy than those continuing infliximab (hazard ratio, 0.025; 95% CI, 0.003 to 0.187; P<0.001). No unexpected adverse events were reported. CONCLUSIONS: Discontinuation of infliximab for patients with Crohn's disease receiving long-term infliximab therapy and in clinical, biochemical, and endoscopic remission leads to a considerable risk of relapse.

Axial spondyloarthritis (axSpA), psoriatic arthritis (PsA), psoriasis, inflammatory bowel disease (IBD), and noninfectious uveitis form a distinct group among the immune mediated inflammatory diseases. Thus, many patients suffer from more than one of these disease manifestations. Here, we will use the term spondylitis-psoriasis-enthesitis-enterocolitis-dactylitis-uveitis-peripheral synovitis (SPEED-UP) spectrum disease. The aim is to review the new targeted pharmacological treatment options for all these diseases. All biological or targeted synthetic drugs with U.S. Food and Drug Administration (FDA) or European Medicines Agency (EMA) approval for any of the diagnoses axSpA, PsA, psoriasis, IBD, or non-infectious uveitis were included. Some of the drugs have documented efficacy in more than one of the diseases, e.g. tumor necrosis factor (TNF) inhibitors. However, other drugs are particularly effective for a specific inflamed tissue and approved in only one or two of the disease entities, e.g. abatacept for peripheral arthritis and vedolizumab for inflammatory bowel disease. This contributes with bedside to bench understanding of the immunology underlying this disease spectrum and provides clinicians with an overview that can assist stratified treatment decisions. We hope that this review will help guide clinicians to speed up treatment of patients with this disease spectrum.
