Tofacitinib for ulcerative colitis:results of the prospective Dutch Initiative on Crohn and Colitis (ICC) registry

Background: Tofacitinib is a Janus kinase inhibitor approved for the treatment of ulcerative colitis (UC). Aim: To evaluate effectiveness, safety and use of tofacitinib in daily practice. Methods: UC patients initiating tofacitinib were prospectively enrolled in 15 hospitals in the Netherlands. Corticosteroid-free clinical remission (short clinical colitis activity index [SCCAI] ≤2), biochemical remission (faecal calprotectin level ≤250 µg/g), combined corticosteroid-free clinical and biochemical remission, predictors of remission, safety outcomes, treatment dose and effect on lipids were determined at weeks 12 and 24. Endoscopic outcomes were evaluated in centres with routine endoscopic evaluation. Results: In total, 123 UC patients (95% anti-TNF, 62% vedolizumab and 3% ustekinumab experienced) were followed for a median duration of 24 weeks (interquartile range 12-26). The proportion of patients in corticosteroid-free clinical, biochemical, and combined corticosteroid-free clinical and biochemical remission rate at week 24 was 29% (n: 22/77), 25% (n: 14/57), and 19% (n: 11/57) respectively. Endoscopic remission (Mayo = 0) was achieved in 21% of patients at week 12 (n: 7/33). Prior vedolizumab exposure was associated with reduced clinical remission (odds ratio 0.33, 95% confidence interval [CI] 0.11-0.94). At week 24, 33% (n: 14/42) of patients still on tofacitinib treatment used 10 mg twice daily. In total, 33 tofacitinib-related adverse events (89 per 100 patient years) occurred, 7 (6% of total cohort) resulted in discontinuation. Cholesterol, HDL and LDL levels increased during induction treatment by 18% (95% CI 9-26), 18% (95% CI 8-28) and 21% (95% CI 14-39) respectively. Conclusion: Tofacitinib is an effective treatment for UC after anti-TNF and vedolizumab failure. However, a relatively high rate of adverse events was observed resulting in discontinuation in 6% of patients

Immediate versus postponed intervention for infected necrotizing pancreatitis

BACKGROUND Infected necrotizing pancreatitis is a potentially lethal disease that is treated with the use of a step-up approach, with catheter drainage often delayed until the infected necrosis is encapsulated. Whether outcomes could be improved by earlier catheter drainage is unknown. METHODS We conducted a multicenter, randomized superiority trial involving patients with infected necrotizing pancreatitis, in which we compared immediate drainage within 24 hours after randomization once infected necrosis was diagnosed with drainage that was postponed until the stage of walled-off necrosis was reached. The primary end point was the score on the Comprehensive Complication Index, which incorporates all complications over the course of 6 months of follow-up. RESULTS A total of 104 patients were randomly assigned to immediate drainage (55 patients) or postponed drainage (49 patients). The mean score on the Comprehensive Complication Index (scores range from 0 to 100, with higher scores indicating more severe complications) was 57 in the immediate-drainage group and 58 in the postponed-drainage group (mean difference, −1; 95% confidence interval [CI], −12 to 10; P=0.90). Mortality was 13% in the immediate-drainage group and 10% in the postponed-drainage group (relative risk, 1.25; 95% CI, 0.42 to 3.68). The mean number of interventions (catheter drainage and necrosectomy) was 4.4 in the immediate-drainage group and 2.6 in the postponed-drainage group (mean difference, 1.8; 95% CI, 0.6 to 3.0). In the postponed-drainage group, 19 patients (39%) were treated conservatively with antibiotics and did not require drainage; 17 of these patients survived. The incidence of adverse events was similar in the two groups. CONCLUSIONS This trial did not show the superiority of immediate drainage over postponed drainage with regard to complications in patients with infected necrotizing pancreatitis. Patients randomly assigned to the postponed-drainage strategy received fewer invasive interventions

Endoscopic Versus Surgical Step-Up Approach for Infected Necrotizing Pancreatitis (ExTENSION):Long-term Follow-up of a Randomized Trial

Background & Aims: Previous randomized trials, including the Transluminal Endoscopic Step-Up Approach Versus Minimally Invasive Surgical Step-Up Approach in Patients With Infected Pancreatic Necrosis (TENSION) trial, demonstrated that the endoscopic step-up approach might be preferred over the surgical step-up approach in patients with infected necrotizing pancreatitis based on favorable short-term outcomes. We compared long-term clinical outcomes of both step-up approaches after a period of at least 5 years. Methods: In this long-term follow-up study, we reevaluated all clinical data on 83 patients (of the originally 98 included patients) from the TENSION trial who were still alive after the initial 6-month follow-up. The primary end point, similar to the TENSION trial, was a composite of death and major complications. Secondary end points included individual major complications, pancreaticocutaneous fistula, reinterventions, pancreatic insufficiency, and quality of life. Results: After a mean follow-up period of 7 years, the primary end point occurred in 27 patients (53%) in the endoscopy group and in 27 patients (57%) in the surgery group (risk ratio [RR], 0.93; 95% confidence interval [CI], 0.65–1.32; P = .688). Fewer pancreaticocutaneous fistulas were identified in the endoscopy group (8% vs 34%; RR, 0.23; 95% CI, 0.08–0.83). After the initial 6-month follow-up, the endoscopy group needed fewer reinterventions than the surgery group (7% vs 24%; RR, 0.29; 95% CI, 0.09–0.99). Pancreatic insufficiency and quality of life did not differ between groups. Conclusions: At long-term follow-up, the endoscopic step-up approach was not superior to the surgical step-up approach in reducing death or major complications in patients with infected necrotizing pancreatitis. However, patients assigned to the endoscopic approach developed overall fewer pancreaticocutaneous fistulas and needed fewer reinterventions after the initial 6-month follow-up.

Safety and drug survival of methotrexate versus tioguanine after failure of conventional thiopurines in patients with Crohn's disease

BackgroundBoth methotrexate (MTX) and tioguanine (TG) can be considered as viable treatment options before initiating biological therapy following failure of conventional thiopurines for Crohn’s disease. It is unclear how safety and effectiveness compare for both therapies. This study aimed to compare tolerability and drug survival of MTX and TG therapy after failure of conventional thiopurines in patients with Crohn′s disease.MethodsWe conducted a retrospective, multi-centre study in five Dutch hospitals, including patients initiating MTX or TG for Crohn’s disease after failure (all causes) of conventional thiopurines. Patients with prior MTX or TG use, MTX or TG not primarily prescribed for Crohn’s disease, or patients receiving concomitant biological treatment at baseline were excluded. Follow-up duration from starting treatment was 104 weeks or until treatment discontinuation. Primary outcome was therapy discontinuation rate due to adverse events (AE). Secondary outcome was ongoing treatment without initiation of biological treatment.ResultsIn total, 221 patients with failure of conventional thiopurines and subsequent therapy with either MTX (n=106) or TG (n=115) were included. Median follow-up was 89 weeks (IQR 28-104). Previous biological failure was present in 28 (26%) MTX and 17 (15%) TG treated patients (p=0.044). Sixty-four (29%) patients (MTX 41.5%, TG 17.4%, p<0.001) discontinued their treatment due to AE during follow-up (Figure 1). Median time until discontinuation due to AE was 16.5 weeks (IQR 8.0–39.0) for MTX and 17.5 weeks (IQR 1.3–69.8) for TG (p=0.925). MTX use was associated with a significantly higher risk of treatment failure due to AE (OR 3.37 [95% CI 1.82–6.25] p<0.001). Previous biological failure was not predictive for MTX or TG failure due to AE (OR 1.086, p=0.828). The most frequent discontinuation reasons were nausea for MTX (n=11) and abdominal pain for TG (n=4). In both groups, 8 (MTX 8%, TG 7%) serious adverse events (SAE) occurred. Infections comprised the majority of all SAE, 4 (50%) for MTX and 7 (88%) for TG. Discontinuation because of elevated liver enzymes occurred in 5 (11%) MTX and 4 (20%) TG treated patients. There were no cases of histological nodular regenerative hyperplasia, liver fibrosis, or cirrhosis. Initiation of concomitant biological therapy was not significantly different (MTX: n=26, TG: n=30, p=0.877). Total monotherapy drug survival after 104 weeks was 46% for TG and 25% for MTX (p<0.001).ConclusionForty-two percent of MTX, compared to 17% of TG treated patients, discontinued therapy due to AE in patients with Crohn’s disease with prior failure of conventional thiopurines. These data may aid in the selection of subsequent therapy after failure of conventional thiopurine therapy

Therapeutic Drug Monitoring of Vedolizumab in Inflammatory Bowel Disease Patients during Maintenance Treatment—TUMMY Study

There are limited data on therapeutic drug monitoring (TDM) in inflammatory bowel disease (IBD) patients treated with vedolizumab (VDZ). Although an exposure–response relation has been demonstrated in the post-induction phase, this relationship is more uncertain in the maintenance phase of treatment. The aim of our study was to determine whether there is an association between VDZ trough concentration and clinical and biochemical remission in the maintenance phase. A prospective, observational multicenter study has been performed on patients with IBD on VDZ in the maintenance treatment (≥14 weeks). Patient demographics, biomarkers, and VDZ serum trough concentrations were collected. Clinical disease activity was scored by the Harvey Bradshaw Index (HBI) for Crohn’s disease (CD) and the Simple Clinical Colitis Activity Index (SCCAI) for ulcerative colitis (UC). Clinical remission was determined as HBI < 5 and SCCAI < 3. Biochemical remission was defined as fecal calprotectin <250 mg/kg and serum CRP <5 mg/L. A total of 159 patients (59 CD, 100 UC) were included. In none of the patient groups, a statistically significant correlation between trough VDZ concentration and clinical remission was observed. Patients in biochemical remission had higher VDZ trough concentrations (p = 0.019). In this population, higher trough VDZ concentrations were associated with biochemical remission but not with clinical remission

Effectiveness of Mindfulness-Based Cognitive Therapy in reducing psychological distress and improving sleep in patients with Inflammatory Bowel Disease: study protocol for a multicentre randomised controlled trial (MindIBD).

Abstract Background Many patients with Inflammatory Bowel Diseases (IBD) suffer from psychological distress, fatigue and sleep disturbances, which are associated with reduced quality of life (QoL) and increased societal costs. Only limited psychosocial treatment options are available. As Mindfulness-Based Cognitive Therapy (MBCT) has demonstrated to improve psychological distress, QoL and sleep in other populations, MBCT might also be effective in patients with IBD. Methods The MindIBD study is a prospective, multicentre, randomised controlled trial comparing MBCT plus Treatment As Usual (TAU) versus TAU alone in a targeted number of 136 IBD patients in remission, aged 16 years and older with at least mild psychological distress (Hospital Anxiety and Depression Scale (HADS) total score ≥ 11). Primary outcome is reduction of psychological distress post-intervention, measured by the HADS. In addition, the effect of MBCT on sleep quality (including actigraphy and electroencephalography recordings), fatigue, disease activity, perceived disease control, QoL and positive mental health will be examined. Assessments will be conducted at baseline and at 3, 6, 9 and 12 months follow-up. Cost-effectiveness will be determined and a process evaluation will be conducted. Discussion This study will provide valuable insight into the clinical effect of MBCT on psychological distress, sleep quality, fatigue and QoL in IBD patients and into the cost-effectiveness. If effective, MBCT can be a valuable addition to the available psychosocial interventions for patients with IBD. Moreover, findings from this study may also be applicable in patients with other chronic conditions. Trial registration ClinicalTrials.gov: NCT04646785, registered on 30/11/2020
