BackgroundIncreasing the interval of administration of anti-TNF agents over the duration specified in the data sheet is not common in inflammatory bowel disease (IBD).AimTo evaluate the outcomes of IBD patients treated with this strategy. MethodsPatients with IBD who were treated with infliximab or adalimumab at intervals > 8 weeks or > 2 weeks, respectively, because of persistent clinical remission, were identified at local databases of the ENEIDA registry (a nationwide registry promoted by the Spanish Working Group in Crohn’s disease and Ulcerative Colitis-GETECCU) of two referral centers. Treatment success was considered if patients remained in clinical remission with the same schedule or without biological therapy at the end of follow-up, and if no return to the conventional schedule, dose-escalation, change in biological agent, or a course of systemic corticosteroids or surgery were required.ResultsEighty-five patients were included, 60 treated with infliximab and 25 with adalimumab. The spaced schedule was initiated after a median of 25 months on anti-TNF treatment (IQR 14–49). Throughout a median follow-up of 34 months (IQR 21–47), fifty patients (59%) fulfilled the success criteria of the spaced strategy. No differences were found regarding type of IBD or anti-TNF agent. Baseline C-reactive protein levels and disease duration at the time of starting anti-TNF treatment were the only factors associated with treatment success. ConclusionsAnti-TNF administration at longer intervals than those provided in the data sheet may be an efficacious, convenient, and cheaper treatment option, particularly in patients in whom anti-TNF treatment was initiated early.

BackgroundOlder age has been reported as a risk factor for severe SARS-CoV-2 disease (COVID-19). The impact of immunosuppressants (IMS) on COVID-19 is still under debate.AimTo describe the incidence and severity of COVID-19 in elderly patients with inflammatory bowel disease (IBD) in relation to the use of IMS.MethodsIBD patients over 65 years of age were selected and grouped in terms of IMS use. Confirmed COVID-19, adherence to IST, comorbidities and concomitant non-IBD-related treatments between 1st of March 2020 to 1st of March 2021 were recorded.ResultsOut of 418 patients included, 89 (21.3%) were on IMS. Thirty-two patients (7.7%) had COVID-19, 7 of whom were on IMS (7.6% not on IMS vs. 7.9% on IMS; P = 0.933) and 7 (22%) patients died.ConclusionsIncidence of COVID-19 among elderly IBD patients was similar to that reported in the background population, regardless of the use of IMS.

The prevalence of penetrating complications in Crohn's disease (CD) increases progressively over time, but evidence on the medical treatment in this setting is limited. The aim of this study was to evaluate the effectiveness of biologic agents in CD complicated with internal fistulizing disease. Adult patients with CD-related fistulae who received at least 1 biologic agent for this condition from the prospectively maintained ENEIDA registry were included. Exclusion criteria involved those receiving biologics for perianal disease, enterocutaneous, rectovaginal, anastomotic, or peristomal fistulae. The primary end point was fistula-related surgery. Predictive factors associated with surgery and fistula closure were evaluated by multivariate logistic regression and survival analyses. A total of 760 patients from 53 hospitals (673 receiving anti-tumor necrosis factors, 69 ustekinumab, and 18 vedolizumab) were included. After a median follow-up of 56 months (interquartile range, 26-102 months), 240 patients required surgery, with surgery rates of 32%, 41%, and 24% among those under anti-tumor necrosis factor, vedolizumab, or ustekinumab, respectively. Fistula closure was observed in 24% of patients. Older patients, ileocolonic disease, entero-urinary fistulae, or an intestinal stricture distal to the origin of the fistula were associated with a higher risk of surgery, whereas nonsmokers and combination therapy with an immunomodulator reduced this risk. Biologic therapy is beneficial in approximately three-quarters of patients with fistulizing CD, achieving fistula closure in 24%. However, around one-third still undergo surgery due to refractory disease. Some patient- and lesion-related factors can identify patients who will obtain more benefit from these drugs.

INTRODUCTION:The coexistence of HIV infection and inflammatory bowel disease (IBD) is uncommon. Data on the impact of HIV on IBD course and its management are scarce. The aim of this study was to describe the IBD phenotype, therapeutic requirements, and prevalence of opportunistic infections (OIs) in IBD patients with a coexistent HIV infection.METHODS:Case-control, retrospective study includes all HIV-positive patients diagnosed with IBD in the Nationwide study on genetic and environmental determinants of inflammatory bowel disease registry. Patients with positive HIV serology (HIV-IBD) were compared with controls (HIV seronegative), matched 1:3 by year of IBD diagnosis, age, sex, and type of IBD.RESULTS:A total of 364 patients (91 HIV-IBD and 273 IBD controls) were included. In the whole cohort, 58% had ulcerative colitis, 35% had Crohn's disease (CD), and 7% were IBD unclassified. The HIV-IBD group presented a significantly higher proportion of proctitis in ulcerative colitis and colonic location in CD but fewer extraintestinal manifestations than controls. Regarding treatments, nonbiological therapies (37.4% vs 57.9%; P = 0.001) and biologicals (26.4% vs 42.1%; P = 0.007), were used less frequently among patients in the HIV-IBD group. Conversely, patients with HIV-IBD developed more OI than controls, regardless of nonbiological therapy use. In the multivariate analysis, HIV infection (odds ratio 4.765, 95% confidence interval (CI) 2.48-9.14; P < 0.001) and having ≥1 comorbidity (OR 2.445, 95% CI 1.23-4.85; P = 0.010) were risk factors for developing OI, while CD was protective (OR 0.372, 95% CI 0.18-0.78; P = 0.009).DISCUSSION:HIV infection seems to be associated with a less aggressive phenotype of IBD and a lesser use of nonbiological therapies and biologicals but entails a greater risk of developing OI.

Abstract Background Anti–tumor necrosis factor agents (anti-TNFs) are efficacious at preventing the postoperative recurrence (POR) of Crohn disease, as demonstrated in 2 randomized controlled trials. However, real-life data for infliximab or adalimumab in this setting are scarce. Our aim was to assess both the efficiency of anti-TNFs at preventing early POR of Crohn disease in clinical practice and the associated risk factors for POR. Methods Patients in whom anti-TNFs were prescribed for the prevention of POR within 3 months after ileocolonic resection and who had an endoscopic assessment within 18 months were identified from the ENEIDA registry. Clinical and endoscopic features were collected within 18 months after surgery. Results In total, 152 patients were included (55 treated with infliximab, 97 with adalimumab, and 39% with concomitant immunosuppressants). Anti-TNF treatment was started after a median time of 29 days (IQR 13–44) after surgery. Eighty-two percent of patients had at least one risk factor for POR, and 82% had been exposed to anti-TNFs before the index surgery. Overall, 34% had endoscopic POR (as defined using a Rutgeerts endoscopic score > i1); 14% had advanced endoscopic POR (>i2); and 20% had clinical POR, with no differences between infliximab and adalimumab. In the multivariate analysis, only perianal disease (odds ratio 2.73, 95% confidence interval [CI] 1.26–5.91) and rectal involvement (odds ratio 2.79, 95% CI 1.09–7.14) were independent predictors of endoscopic POR. Conclusions In clinical practice, anti-TNFs for the prevention of POR of Crohn disease are frequently used in patients experienced with anti-TNFs and with concomitant immunosuppressants. The efficacy of infliximab and adalimumab for POR prevention is similar and in accordance with the results obtained in randomized controlled trials. Video Abstract 10.1093/ibd/izz084_video Video Abstract izz084_video 6028411486001 This is the largest series assessing the use of anti-TNF agents for POR prevention in clinical practice. The efficacy of infliximab and adalimumab for POR prevention is similar and are in accordance with the results obtained in RCTs. Perianal disease and rectal involvement were independent predictors of endoscopic POR.

Abstract Background Limited data are available on the outcome of inflammatory bowel disease (IBD) in patients with solid organ transplantation (SOT). We describe the natural history of pre-existing IBD and de novo IBD after SOT. Methods This was a retrospective, multicenter study that included patients with pre-existing IBD at the time of SOT and patients with de novo IBD after SOT. The primary outcome was IBD progression, defined by escalation of medical treatment, surgical therapy, or hospitalization due to refractory IBD. Risk factors were identified using multivariate Cox proportional hazard analysis. Results A total of 177 patients (106 pre-existing IBD and 71 de novo IBD) were included. Most patients with pre-existing IBD (92.5%) were in remission before SOT. During follow-up, 32% of patients with pre-existing IBD had disease progression, with a median time between SOT and IBD progression of 2.2 (interquartile range, 1.3-4.6) years. In the de novo cohort, 55% of patients had disease progression with a median time to flare of 1.9 (interquartile range, 0.8-3.9) years after diagnosis. In the pre-existing IBD cohort, active IBD at the time of SOT (hazard ratio, 1.80; 95% confidence interval, 1.14-2.84; P = .012) and the presence of extraintestinal manifestations (hazard ratio, 3.10; 95% confidence interval, 1.47-6.54; P = .003) were predictive factors for IBD progression. Conclusions One-third of patients with pre-existing IBD and about half of patients with de novo IBD have disease progression after SOT. Active IBD at the time of SOT and the presence of extraintestinal manifestations were identified as risk factors for IBD progression.

Patients with Crohn's disease experiencing endoscopic postoperative recurrence (POR) may benefit from antitumor necrosis factor (TNF) agents but scarce data on this are available. Our aim was to assess the efficacy of anti-TNF in improving mucosal lesions in patients with endoscopic POR. Multicenter, retrospective, study of patients with Crohn's disease who underwent therapy with anti-TNF agents for endoscopic POR (Rutgeerts score > i1). Treatment outcomes were assessed by the findings in the last ileocolonoscopy performed after anti-TNF therapy was initiated. Endoscopic improvement and remission were defined as any reduction in the baseline Rutgeerts score and by a Rutgeerts score < i2, respectively. A total of 179 patients were included, 83 were treated with infliximab and 96 with adalimumab. Median time on anti-TNF therapy at the last endoscopic assessment was 31 months (interquartile range, 13-54). Endoscopic improvement was observed in 61%, including 42% who achieved endoscopic remission. Concomitant use of thiopurines and treatment with infliximab were associated with endoscopic improvement (odds ratio [OR] 2.15, 95% confidence interval [CI] 1.04-4.46; P = 0.03, and OR 2.34, 95% CI 1.18-4.62; P < 0.01, respectively) and endoscopic remission (OR 3.16, 95% CI 1.65-6.05; P < 0.01, and OR 2.01, 95% CI 1.05-3.88; P = 0.04, respectively) in the multivariable logistic regression analysis. These results were confirmed in a propensity-matched score analysis. In patients with endoscopic POR, anti-TNF agents improve mucosal lesions in almost two-thirds of the patients. In this setting, concomitant use of thiopurines and use of infliximab seem to be more effective in improving mucosal lesions.

Purpose Nivolumab, a monoclonal antibody-targeting programmed cell death protein-1, is being increasingly used for the treatment of some advanced neoplasms. Several of its adverse effects are a result of the upregulation of T cells, with colitis as one of the most severe, and a challenging differential diagnosis with ulcerative colitis. However, few real-life clinical practice cases have been reported beyond trials. Our aim was to report a series of new cases, reviewing previously communicated endoscopic-proven nivolumab-induced colitis. Method All patients treated with nivolumab in three university centers were identified and those who developed immune-mediated colitis (defined as the presence of diarrhea and evidence of colitis demonstrated by colonoscopy) were described. Additionally, a review of case reports of nivolumab-induced colitis reported in the literature up to March 2018 was performed. Results Six new cases of nivolumab-induced colitis and 13 previously reported cases out of randomized clinical trials are described. Colonoscopy showed a mucosal pattern mimicking ulcerative colitis in a large proportion of patients. Clostridium difficile superinfection was observed in two out of 19 cases. All but three patients definitively discontinued nivolumab therapy. Most patients were initially managed with oral or intravenous corticosteroids, but five of them required rescue therapy with infliximab. Conclusions Nivolumab-induced colitis may mimic ulcerative colitis. Steroid therapy (oral or intravenously) is often efficient, but one-fourth of patients need rescue therapy with anti-TNF. Intestinal superinfection with Clostridium difficile or cytomegalovirus should be ruled out before starting immunosuppressive therapy.

BackgroundThe outbreak of COVID19 evolved rapidly into a global pandemic, forcing hospitals, including inflammatory bowel disease (IBD) referral units, to change their practices to ensure quality of care. AimsTo describe the clinical outcomes and the fulfilment of the treatment schedule of patients with IBD treated with biological agents in a single-center of a red-zone of the pandemic, and to report the patients’ perceptions about COVID-19 and the measures adopted at our center.MethodsTherapeutic adherence and clinical outcomes were collected for all patients undergoing treatment with intravenous biologicals and subcutaneous biologicals at our center. A telephone survey was also performed to assess these patients’ perceptions of the COVID pandemic and the related measures adopted at their IBD unit.ResultsA total of 234 patients were included (117 on intravenous and 117 on subcutaneous biologicals). Only 10% of patients postponed intravenous infusions intentionally and 5% postponed the collection of subcutaneous biologicals at the hospital pharmacy. Only five confirmed COVID-19 cases were registered (2.1%), all of them of mild severity. One hundred and fifty-five patients participated in the survey (77 on intravenous and 78 on subcutaneous drugs). Fear of going to the hospital was the most common reason for postponing biological administrations. Among those on combination therapy, only 7% admitted to have withdrawn immunosuppressants.ConclusionsAdherence to intravenous and subcutaneous biological therapies during the pandemic was high in a single-center cohort of IBD patients even though the cumulative incidence of confirmed COVID-19 was low.
