Abstract

Background and aim: Pneumocystis jirovecii pneumonia [PJP] is a very rare, potentially life-threatening pulmonary fungal infection that occurs in immunocompromised individuals including patients with inflammatory bowel disease [IBD]. Our aim was to describe immunosuppressive treatment exposure as well as the outcome in IBD patients with PJP.Methods: PJP cases were retrospectively collected through the COllaborative Network For Exceptionally Rare case reports of the European Crohn's and Colitis Organisation. Clinical data were provided through a case report form.Results: In all, 18 PJP episodes were reported in 17 IBD patients [10 ulcerative colitis and seven Crohn's disease]. The median age at PJP diagnosis was 55 years (interquartile range [IQR], 40-68 years]. Two PJP [11.1%] occurred in patients on triple immunosuppression, 10 patients [55.6%] had double immunosuppressive treatment, four patients [22.2%] had monotherapy and two PJP occurred in absence of immunosuppressive treatment [one in a human immunodeficiency virus patient and one in a patient with a history of autologous stem cell transplantation]. Immunosuppressive therapies included steroids [n = 12], thiopurines [n = 10], infliximab [n = 4], ciclosporin [n = 2], methotrexate [n = 1], and tacrolimus [n = 1]. None of the patients diagnosed with PJP had received prophylaxis. All patients were treated by trimethoprim/sulphamethoxazole or atovaquone and an intensive care unit [ICU] stay was required in seven cases. Two patients [aged 71 and 32 years] died, and one patient had a recurrent episode 16 months after initial treatment. Evolution was favourable for the others.Conclusion: This case series reporting potentially fatal PJP highlights the need for adjusted prophylactic therapy in patients with IBD on immunosuppressive therapy.

Abstract

International audience; Background The identification of patients at high risk of a disabling disease course would be invaluable in guiding initial therapy in Crohn’s disease (CD). Our objective was to evaluate a combination of clinical, serological, and genetic factors to predict complicated disease course in pediatric-onset CD. Methods Data for pediatric-onset CD patients, diagnosed before 17 years of age between 1988 and 2004 and followed more than 5 years, were extracted from the population-based EPIMAD registry. The main outcome was defined by the occurrence of complicated behavior (stricturing or penetrating) and/or intestinal resection within the 5 years following diagnosis. Lasso logistic regression models were used to build a predictive model based on clinical data at diagnosis, serological data (ASCA, pANCA, anti-OmpC, anti-Cbir1, anti-Fla2, anti-Flax), and 369 candidate single nucleotide polymorphisms. Results In total, 156 children with an inflammatory (B1) disease at diagnosis were included. Among them, 35% (n = 54) progressed to a complicated behavior or an intestinal resection within the 5 years following diagnosis. The best predictive model (PREDICT-EPIMAD) included the location at diagnosis, pANCA, and 6 single nucleotide polymorphisms. This model showed good discrimination and good calibration, with an area under the curve of 0.80 after correction for optimism bias (sensitivity, 79%, specificity, 74%, positive predictive value, 61%, negative predictive value, 87%). Decision curve analysis confirmed the clinical utility of the model. Conclusions A combination of clinical, serotypic, and genotypic variables can predict disease progression in this population-based pediatric-onset CD cohort. Independent validation is needed before it can be used in clinical practice.

Abstract

International audience; Background While the effect of anti-TNFs on postoperative outcomes in patients with Crohn's disease (CD) has been widely studied, the impact of vedolizumab and ustekinumab on the risk of postoperative complications remains poorly known. Methods All consecutive patients who underwent intestinal resection for CD between July 2014 and April 2022 within 22 French centers were included in a retrospective cohort. The risk of early post-operative complications (≤30days) in patients exposed to biologics was compared to patients not exposed by logistic regression and propensity score-matched analysis adjusted for age, previous intestinal resection, corticosteroids or immunosuppressants exposure, disease activity, presence of abscess, urgent surgery and initial stoma (preoperative contra-indication to anastomosis). Results Among the 1201 patients included, respectively 491 (41%), 76 (6.3%) and 57 (4.7%) were exposed to anti-TNFs, ustekinumab, or vedolizumab within six months before surgery. A total of 317 (26.4%) patients had at least one complication of which 123 (38%) were considered as severe (DINDO III/IV). New surgery was necessary in 69 (5.7%) patients and secondary stoma in 23 (1.9%). Three deaths were observed (0.25%). The rates of overall complications in patients not exposed to biologics, exposed to anti-TNFs, ustekinumab or vedolizumab were respectively 26.1%, 25.1%, 34.7% and 29.8%. The risks of intra-abdominal infectious complications in these four groups were respectively 13.5%, 11.1%, 13.3% and 8.8%. In multivariate analysis, age [OR, 1.02 (1.01-1.04); p=0.004], disease activity [OR, 8.36 (1.79 – 149); p=0.037], the presence of an abscess [OR, 2.01 (1.25-3.20); p=0.004] and initial stoma [OR, 1.70 (1.10 –2.61); p=0.016] were significantly associated with intra-abdominal infectious complications. Conversely, preoperative enteral nutrition [OR, 0.12 (0.01 -0.59); p=0.040] was associated with a reduction in this risk. Exposure to anti-TNFs [OR, 0.80 (0.51-1.24); p=0.31], ustekinumab [OR, 1.17 (0.39-3.51); p=0.78] and vedolizumab [OR, 1.28 (0.32-5.17); p=0.72] within the 3 months before surgery were not associated with the risk of intra-abdominal infectious complications. Similar results were observed in patients exposed to these treatments in the month before surgery. Conclusion In this large cohort, a quarter of patients operated on for CD presented an early postoperative complication and 10% a severe complication. Preoperative exposure to anti-TNFs, vedolizumab or ustekinumab was not associated with an increased risk of early postoperative complications. Preoperative enteral nutrition was associated with a reduced risk of intra-abdominal infectious complication.

Abstract

Genome-wide association studies (GWASs) have identified hundreds of loci associated with Crohn's disease (CD). However, as with all complex diseases, robust identification of the genes dysregulated by noncoding variants typically driving GWAS discoveries has been challenging. Here, to complement GWASs and better define actionable biological targets, we analyzed sequence data from more than 30,000 patients with CD and 80,000 population controls. We directly implicate ten genes in general onset CD for the first time to our knowledge via association to coding variation, four of which lie within established CD GWAS loci. In nine instances, a single coding variant is significantly associated, and in the tenth, ATG4C, we see additionally a significantly increased burden of very rare coding variants in CD cases. In addition to reiterating the central role of innate and adaptive immune cells as well as autophagy in CD pathogenesis, these newly associated genes highlight the emerging role of mesenchymal cells in the development and maintenance of intestinal inflammation.Large-scale sequence-based analyses identify novel risk variants and susceptibility genes for Crohn's disease, and implicate mesenchymal cell-mediated intestinal homeostasis in disease etiology.

Abstract

Pneumocystis jirovecii pneumonia (PJP) is a very rare, potentially life-threatening pulmonary fungal infection that occurs in immunocompromised individuals including patients with inflammatory bowel disease (IBD). Our aim was to describe immunosuppressive treatment exposure as well as the outcome in IBD patients with PJP. PJP cases were retrospectively collected through the COllaborative Network For Exceptionally Rare case reports of the European Crohn's and Colitis Organization. Clinical data were provided through a case report form. 18 PJP episodes were reported in 17 IBD patients (10 ulcerative colitis and 7 Crohn's disease). The median age on PJP diagnosis was 55 years (IQR, 40-68 years). Two PJP (11.1%) occurred in patients on triple immunosuppression, 10 patients (55.6%) had double immunosuppressive treatment, 4 patients (22.2%) had monotherapy and 2 PJP occurred in absence of immunosuppressive treatment (one in a human immunodeficiency virus patient and one in a patient with a history of autologous stem cell transplantation). Immunosuppressive therapies included steroids (n=12), thiopurines (n=10), infliximab (n=4), ciclosporin (n=2), methotrexate (n=1) and tacrolimus (n=1). None of the patients diagnosed with PJP had received prophylaxis. All patients were treated by trimethoprim/sulfamethoxazole or atovaquone and an ICU stay was required in 7 cases. Two patients (aged 71 and 32 years) died, and one patient had a recurrent episode 16 months after initial treatment. Evolution was favourable for the others. This case series reporting potentially fatal PJP highlights the need for adjusted prophylactic therapy in patients with IBD on immunosuppressive therapy.

Abstract

Item does not contain fulltext, BACKGROUND: Active-comparator trials are important to inform patient and physician choice. We aimed to evaluate the efficacy and safety of monotherapy with either ustekinumab or adalimumab in biologic-naive patients with moderately to severely active Crohn's disease. METHODS: We conducted a randomised, double-blind, parallel-group, active-comparator, phase 3b trial (SEAVUE) at 121 hospitals or private practices in 18 countries. We included biologic-naive patients aged 18 years or older with moderately to severely active Crohn's disease and a Crohn's Disease Activity Index (CDAI) score of 220-450, who had not responded to or were intolerant to conventional therapy (or were corticosteroid dependent) and had at least one ulcer of any size at baseline endoscopic evaluation. Eligible patients were randomly assigned (1:1; via an interactive web response system) to receive ustekinumab (approximately 6 mg/kg intravenously on day 0, then 90 mg subcutaneously once every 8 weeks) or adalimumab (160 mg on day 0, 80 mg at 2 weeks, then 40 mg once every 2 weeks, subcutaneously) through week 56. Study treatments were administered as monotherapy and without dose modifications. Patients, investigators, and study site personnel were masked to treatment group assignment. The primary endpoint was the proportion of patients who were in clinical remission (CDAI score <150) at week 52 in the intention-to-treat population (ie, all patients who were randomly assigned to a treatment group). This trial is registered with ClinicalTrials.gov, NCT03464136, and EudraCT, 2017-004209-41. FINDINGS: Between June 28, 2018, and Dec 12, 2019, 633 patients were assessed for eligibility and 386 were enrolled and randomly assigned to receive ustekinumab (n=191) or adalimumab (n=195). 29 (15%) of 191 patients in the ustekinumab group and 46 (24%) of 195 in the adalimumab group discontinued study treatment before week 52. There was no significant difference between the ustekinumab and adalimumab groups in th

Abstract

Environmental and lifestyle factors play an important role in the natural history of Crohn's disease and ulcerative colitis. A group of international experts from the International Organization for the Study of Inflammatory Bowel Diseases voted on a series of consensus statements to inform the management of inflammatory bowel disease (IBD). The recommendations include avoiding traditional cigarette smoking in patients with Crohn's disease or ulcerative colitis, screening for symptoms of depression, anxiety, and psychosocial stressors at diagnosis and during flares (with referral to mental health professionals when appropriate), and encouraging regular physical activity as tolerated. Patients using dietary approaches for treatment of their IBD should be encouraged to adopt diets that are best supported by evidence and involve monitoring for the objective resolution of inflammation. We recommend formal assessment for obesity and nutritional deficiencies, and patients should be encouraged to maintain a normal body-mass index. A shared decision-making approach to contraception should include the consideration of IBD-related factors, and risk factors for venous thromboembolism. Long-term or frequent use of high-dose non-steroidal anti-inflammatory drugs should be avoided. For primary prevention of disease in the offspring of patients with IBD, we recommend avoiding passive exposure to tobacco, using antibiotics judiciously, and considering breastfeeding when able.
