Influence of familial forms of inflammatory bowel disease on the use of immunosuppressants, biological agents, and surgery in the era of biological therapies. Results from the ENEIDA project.

BACKGROUND AND AIMS: Familial inflammatory bowel disease (IBD) history is a controversial prognostic factor in IBD. We aimed to evaluate the impact of a familial history of IBD on the use of medical and surgical treatments in the biological era. METHODS: Patients included in the prospectively maintained ENEIDA database and diagnosed with IBD after 2005 were included. Familial forms were defined as those cases with at least one first-degree relative diagnosed with IBD. Disease phenotype, the use of biological agents, or surgical treatments were the main outcomes. RESULTS: A total of 5263 patients [2627 Crohn's disease (CD); 2636 ulcerative colitis (UC)] were included, with a median follow-up of 31 months. Of these, 507 (10%) corresponded to familial forms. No clinical differences were observed between familial and sporadic IBD forms except a lower age at IBD diagnosis and a higher rate of males in familial forms of UC. In CD, the proportions of patients treated with thiopurines (54.4% vs 46.7%; P = .015) and survival time free of thiopurines (P = .009) were lower in familial forms. No differences were found regarding the use of biological agents. Concerning surgery, a higher rate of intestinal resections was observed in sporadic CD (14.8% vs 9.9%, P = .027). No differences were observed in UC. CONCLUSIONS: In the era of biological therapies, familial and sporadic forms of IBD show similar phenotypes and are managed medically in a similar way; whether these is due to lack of phenotypical differences or an effect of biological therapies is uncertain. What is already known on this topic: IBD's etiopathogenesis points to an interaction between environmental and genetic factors, being familial history a controversial prognostic factor. Biological agents use and need for surgery regarding familial or sporadic forms of IBDs present conflicting results. What this study adds: Familial and sporadic forms of IBD have similar phenotypes and are managed medically and surgically in a similar way. How this study might affect research, practice or policy: Familial aggregation should not be considered a factor associated with more aggressive disease.

Comparative Study of the Effectiveness of Vedolizumab Versus Ustekinumab After Anti-TNF Failure in Crohn's Disease (Versus-CD): Data from the ENEIDA Registry.

BACKGROUND: Both vedolizumab and ustekinumab are approved for the management of Crohn's disease [CD]. Data on which one would be the most beneficial option when anti-tumour necrosis factor [anti-TNF] agents fail are limited. AIMS: To compare the durability, effectiveness, and safety of vedolizumab and ustekinumab after anti-TNF failure or intolerance in CD. METHODS: CD patients from the ENEIDA registry who received vedolizumab or ustekinumab after anti-TNF failure or intolerance were included. Durability and effectiveness were evaluated in both the short and the long term. Effectiveness was defined according to the Harvey-Bradshaw index [HBI]. The safety profile was compared between the two treatments. The propensity score was calculated by the inverse probability weighting method to balance confounder factors. RESULTS: A total of 835 patients from 30 centres were included, 207 treated with vedolizumab and 628 with ustekinumab. Dose intensification was performed in 295 patients. Vedolizumab [vs ustekinumab] was associated with a higher risk of treatment discontinuation (hazard ratio [HR] 2.55, 95% confidence interval [CI]: 2.02-3.21), adjusted by corticosteroids at baseline [HR 1.27; 95% CI: 1.00-1.62], moderate-severe activity in HBI [HR 1.79; 95% CI: 1.20-2.48], and high levels of C-reactive protein at baseline [HR 1.06; 95% CI: 1.02-1.10]. The inverse probability weighting method confirmed these results. Clinical response, remission, and corticosteroid-free clinical remission were higher with ustekinumab than with vedolizumab. Both drugs had a low risk of adverse events with no differences between them. CONCLUSION: In CD patients who have failed anti-TNF agents, ustekinumab seems to be superior to vedolizumab in terms of durability and effectiveness in clinical practice. The safety profile is good and similar for both treatments.

Duration of smoking cessation in patients with inflammatory bowel disease.

BACKGROUND AND OBJECTIVES: Smoking can worsen inflammatory bowel disease (IBD), although evidence regarding the duration of cessation is scarce. The objectives of the study were to determine the duration of abstinence and identify the characteristics of relapse in IBD patients. PATIENTS AND METHODS: Using the local database of a nationwide registry of patients with IBD, we identified patients who were active smokers at the time of IBD diagnosis and invited them to participate in the study. Patients were asked about their smoking habit and those who were ex-smokers constituted the study cohort. We obtained clinical and smoking-related data of ex-smokers from medical records and telephone interviews. We measured nicotine dependence using the Fagerström Test for Nicotine Dependence (FTND). RESULTS: We enrolled 121 IBD patients who were ex-smokers: 89 patients with Crohn's disease (CD) and 33 patients with ulcerative colitis (UC). The median age at cessation was lower in patients with CD (38 years) than in patients with UC (46 years) (p=0.002). Follow-up time was shorter in CD patients than in UC patients (114 vs. 168 months, p=0.035). No difference was found in the FTND score. Relapse was more common in CD patients (46%) than in UC patients (24%) (p=0.029), although time to first relapse was similar in both groups of patients (12 and 15 months, respectively; p=0.056). Nicotine dependence was the only independent factor associated with relapse. CONCLUSIONS: The risk of smoking relapse was high, especially in CD patients, although their dependence level was similar to that of UC patients.

Perception of the need for dietary advice and dietary modifications in inflammatory bowel disease patients. / Percepción de la necesidad de asesoramiento dietético y modificaciones alimentarias en pacientes con enfermedad inflamatoria intestinal.

BACKGROUND AND AIM: In inflammatory bowel disease (IBD), diet can be perceived as a trigger for relapses or clinical worsening, dietary modifications are frequent and not derived from professional advice. The aim of this study was to evaluate the perception of the need for dietary advice in patients with IBD, to know the dietary modifications adopted and, it's effect on IBD. METHODS: An anonymous structured questionnaire with a visual analog scale (0-10) was distributed to consecutive outpatients from our IBD unit. RESULTS: A total of 124 complete the questionnaire (54% ulcerative colitis, 46% Crohn's disease). Mean age was 47±12 years. Dietary advice provided in the clinic was assessed with a median score of 7 (IIC, 4.50-9.00). 40% sought external dietary advice, often during the first year after diagnosis (70%). The most frequent dietary recommendations from an external professional were: dairy free diet (29%), low fat (27%), gluten free (23%), and low fiber (21%). Dietary advice from external source was assessed with a median score of 7.50 (IIC, 5.50-9.50), improving digestive symptoms in 73% of cases. Regarding dietary modifications, 61% excluded some foods (57% permanently) and 11% fasted on their own decision. CONCLUSIONS: IBD patient show a clear need for dietary advice, especially at the time of IBD diagnosis. Early specific and in-depth dietary information would increase patient satisfaction and could prevent the adoption of unjustified exclusion diets.

Effectiveness and safety of methotrexate monotherapy in patients with Crohn's disease refractory to anti-TNF-α: results from the ENEIDA registry.

BACKGROUND: Methotrexate can be used to maintain remission in Crohn's disease patients who are intolerant to thiopurines. Data on its use as monotherapy in other scenarios are limited. AIM: To assess the effectiveness of methotrexate monotherapy in Crohn's disease patients after previous failure to anti-tumour necrosis factor (anti-TNFα) drugs. METHODS: A retrospective, observational multicentre study of data from the Spanish ENEIDA registry. Participants were patients with active Crohn's disease and previous failure to anti-TNFα started on methotrexate monotherapy. Short-term effectiveness was assessed at 12-16 weeks based on Harvey-Bradshaw index (HBI): clinical remission as HBI ≤ 3 points and clinical response as HBI drop of ≥ 3 points over baseline. Long-term effectiveness was defined as steroid-free methotrexate persistence from 12 to 16 weeks until maximum follow up. Adverse events were recorded. RESULTS: Data were compiled for 110 patients treated with methotrexate after a failed response to one (39%) or two (55.6%) anti-TNFα agents. Short-term clinical response and remission rates were 60% and 30.9% respectively. Of 74 patients who continued after week 16, long-term effectiveness was achieved in 82% and 74% at 12 and 24 months respectively. In the multivariate analysis, non-remission at short term (vs remission) was associated with long-term failure (HR 2.58, 95%CI 1.95-3.68, P = 0.028). Adverse events (evaluated in 100 patients) were recorded in 44%, and in 30.4% of these patients, they led to methotrexate discontinuation. CONCLUSIONS: The benefits observed suggest methotrexate monotherapy could be a valid option in Crohn's disease patients with previous failure to anti-TNFα.

Real-life experience with 4 years of golimumab persistence in ulcerative colitis patients.

Golimumab has demonstrated its long-term efficacy and safety in ulcerative colitis in clinical trials, but no data of long-term persistence has been published from real world. To estimate long-term persistence of golimumab, as well as factors associated with longer persistence, in patients with ulcerative colitis in real life. Observational multicentre study including adult patients with ulcerative colitis treated with golimumab and with at least twelve months of follow-up. We included 190 patients, 105 (55.26%) naive to anti-TNF, with mean disease duration of 9.32 ± 8.09 years. Probability of persistence was 63%, 46%, 39% and 27% at 1, 2, 3 and 4 years, respectively. Persistence was lower in patients with primary failure to previous anti-TNF. Eighty-two (43.16%) patients needed dose intensification during follow-up, with a mean time until intensification of 8.03 ± 8.64 months. Dose intensification and lower disease duration predicted higher persistence with golimumab (p = 0.037 and p = 0.008, respectively). During a follow-up of 17.25 ± 15.83 months, 32 (16.5%) patients needed hospitalisation and 11 (6%) underwent colectomy. No unexpected adverse events were reported. Golimumab has demonstrated good persistence and safety profile for long treatment in ulcerative colitis patients.

Clinical Outcomes of Golimumab as First, Second or Third Anti-TNF Agent in Patients with Moderate-to-Severe Ulcerative Colitis.

BACKGROUND: Golimumab efficacy data in ulcerative colitis (UC) are limited to anti-tumor necrosis factor α (TNF)-naive patients. The aim of this study was to assess the short-term and long-term efficacy of golimumab used as first, second, or third anti-TNF in UC in a real-life clinical setting. METHODS: This retrospective multicenter cohort study included patients with moderate-to-severe UC treated with golimumab. The primary efficacy endpoints were short-term partial Mayo score response, long-term golimumab failure-free survival, and colectomy-free survival. RESULTS: In 142 patients with UC, golimumab was administered as first (40%), second (23%), or third anti-TNF (37%). Ninety-two patients (65%, 95% confidence interval 56.6-73) achieved short-term clinical response. Forty-five patients (32%, 95% confidence interval 23.7-39.7) achieved clinical remission. Response rates for golimumab were 75% as first anti-TNF, 70% as second anti-TNF (ns versus first anti-TNF), and 50% as third anti-TNF (P = 0.007 versus first anti-TNF). After 12 months median follow-up (interquartile range 6-18), 60 patients (42%, 95% confidence interval 34-51) had golimumab failure, and 15 patients (11%) needed colectomy. Thirty-one patients (22%) needed golimumab dose escalation, and 71% of these regained response after escalation. Starting maintenance with 100 mg golimumab doses and short-term nonresponse were independent predictors of golimumab failure. CONCLUSIONS: In this real-life cohort of patients with UC, golimumab therapy was effective for inducing and maintaining clinical response. Although anti-TNF-naive patients had better outcomes, golimumab was also effective in anti-TNF-experienced patients. Only the patients given golimumab after previous failure of 2 anti-TNF agents had significantly worse outcomes. Golimumab dose escalation was beneficial and safe.
