Splanchnic Vein Thrombosis in Inflammatory Bowel Disease : An Observational Study from the ENEIDA Registry and Systematic Review
Background: Thromboembolic events are frequent among patients with inflammatory bowel disease (IBD). However, there is little information on the prevalence, features and outcomes of splanchnic vein thrombosis (SVT) in patients with IBD. Aims: To describe the clinical features and outcomes of SVT in patients with IBD and to perform a systematic review of these data with published cases and series. Methods: A retrospective observational study from the Spanish nationwide ENEIDA registry was performed. A systematic search of the literature was performed to identify studies with at least one case of SVT in IBD patients. Results: A new cohort of 49 episodes of SVT from the Eneida registry and 318 IBD patients with IBD identified from the literature review (sixty studies: two multicentre, six single-centre and fifty-two case reports or case series) were analysed. There was a mild predominance of Crohn's disease and the most frequent clinical presentation was abdominal pain with or without fever followed by the incidental finding in cross-sectional imaging techniques. The most frequent SVT location was the main portal trunk in two-thirds of the cases, followed by the superior mesenteric vein. Anticoagulation therapy was prescribed in almost 90% of the cases, with a high rate of radiologic resolution of SVT. Thrombophilic conditions other than IBD itself were found in at least one-fifth of patients. Conclusions: SVT seems to be a rare (or underdiagnosed) complication in IBD patients. SVT is mostly associated with disease activity and evolves suitably when anticoagulation therapy is started
Trends in Targeted Therapy Usage in Inflammatory Bowel Disease : TRENDY Study of ENEIDA
Markers that allow for the selection of tailored treatments for individual patients with inflammatory bowel diseases (IBD) are yet to be identified. Our aim was to describe trends in real-life treatment usage. For this purpose, patients from the ENEIDA registry who received their first targeted IBD treatment (biologics or tofacitinib) between 2015 and 2021 were included. A subsequent analysis with Machine Learning models was performed. The study included 10,009 patients [71% with Crohn's disease (CD) and 29% with ulcerative colitis (UC)]. In CD, anti-TNF (predominantly adalimumab) were the main agents in the 1st line of treatment (LoT), although their use declined over time. In UC, anti-TNF (mainly infliximab) use was predominant in 1st LoT, remaining stable over time. Ustekinumab and vedolizumab were the most prescribed drugs in 2nd and 3rd LoT in CD and UC, respectively. Overall, the use of biosimilars increased over time. Machine Learning failed to identify a model capable of predicting treatment patterns. In conclusion, drug positioning is different in CD and UC. Anti-TNF were the most used drugs in IBD 1st LoT, being adalimumab predominant in CD and infliximab in UC. Ustekinumab and vedolizumab have gained importance in CD and UC, respectively. The approval of biosimilars had a significant impact on treatment
Effectiveness and safety of ustekinumab in ulcerative colitis: Real-world evidence from the ENEIDA registry
Abstract Background: The development program (UNIFI) has shown promising results of ustekinumab in ulcerative colitis (UC) treatment that should be confirmed in clinical practice. Aims: To evaluate the durability, effectiveness and safety of ustekinumab in UC in real-life. Methods: Patients included in the prospectively maintained ENEIDA registry who received at least one intravenous dose of ustekinumab due to active UC [Partial Mayo Score (PMS) >2] were included. Clinical activity and effectiveness were defined based on PMS. Short-term response was assessed at week 16. Results: A total of 95 patients were included. At week 16, 53% of patients had response (including 35% of patients in remission). In the multivariate analysis, elevated serum C-reactive protein was the only variable significantly associated with lower likelihood of achieving remission. Remission was achieved in 39% and 33% of patients at weeks 24 and 52, respectively. Thirty-six percent of patients discontinued the treatment with ustekinumab during a median follow-up of 31 weeks. The probability of maintaining ustekinumab treatment was 87% at week 16, 63% at week 56, and 59% at week 72; primary failure was the main reason for ustekinumab discontinuation. No variable was associated with risk of discontinuation. Three patients reported adverse events; one of them had a fatal severe SARS-CoV-2 infection. Conclusions: Ustekinumab is effective both in the short and the long-term in real-life, even in a highly refractory cohort. Higher inflammatory burden at baseline correlated with lower probability of achieving remission. Safety was consistent with the known profile of ustekinuma
Clinical and treatment outcomes of a second subcutaneous or intravenous anti-TNF in patients with ulcerative colitis treated with two consecutive anti-TNF agents: data from the ENEIDA registry
Background: Infliximab seems to be the most efficacious of the three available anti-TNF agents for ulcerative colitis (UC) but little is known when it is used as the second anti-TNF. Objectives: To compare the clinical and treatment outcomes of a second subcutaneous or intravenous anti-TNF in UC patients. Design: Retrospective observational study. Methods: Patients from the ENEIDA registry treated consecutively with infliximab and a subcutaneous anti-TNF (or vice versa), naïve to other biological agents, were identified and grouped according to the administration route of the first anti-TNF into IVi (intravenous initially) or SCi (subcutaneous initially). Results: Overall, 473 UC patients were included (330 IVi and 143 SCi). Clinical response at week 14 was 42.7% and 48.3% in the IVi and SCi groups (non-statistically significant), respectively. Clinical remission rates at week 52 were 32.8% and 31.4% in the IVi and SCi groups (nonsignificant differences), respectively. A propensity-matched score analysis showed a higher clinical response rate at week 14 in the SCi group and higher treatment persistence in the IVi group. Regarding long-term outcomes, dose escalation and discontinuation due to the primary failure of the first anti-TNF and more severe disease activity at the beginning of the second anti-TNF were inversely associated with clinical remission. Conclusion: The use of a second anti-TNF for UC seems to be reasonable in terms of efficacy, although it is particularly reduced in the case of the primary failure of the first anti-TNF. Whether the second anti-TNF is infliximab or subcutaneous does not seem to affect efficacy
