- Background. The thrombosis risk is increased in active ulcerative colitis. The limited number of reported complications have predominantly been cerebrovascular but other vessel territories may also be affected. Patient. During a severe attack of ulcerative colitis a 37-year-old woman suffered occlusion of all left coronary artery branches. Serial angiographies showed progressive recanalisation of the coronary arteries during anticoagulation, but no atherosclerotic stenosis. The cause of infarction was thus considered to be an extensive coronary thrombosis. However, a large battery of blood tests failed to identify any procoagulant abnormality. Conclusion. Evidence is now accumulating that the increased thrombosis risk also may involve the coronary arteries, even in young patients. To the best of our knowledge this is the third reported case ofmyocardial infarction despite angiographically normal coronary arteries in a patient with active ulcerative colitis. The extent of affected myocardiumwas in this case exceptionally large.

- Patienter med svårt skov av ulcerös kolit bör vårdas på sjukhus och handläggas av gastroenterolog och kolorektal kirurg i nära samarbete.Skovets svårighetsgrad kan underskattas, varför noggrann bedömning av inflammationens utbredning och svårighetsgrad enligt validerade kriterier är viktigt.Intravenös behandling med kortikosteroider är en av hörnstenarna i den akuta behandlingen.Patienter som inte förbättras på denna behandling, bör erbjudas medicinsk »rescue-behandling« eller kolektomi.Infliximab har visats vara en effektiv rescue-behandling och kan minska behovet av kolektomi inom de första 3 månaderna och upp till 3 år.

- Objective: Randomized controlled trials have shown the effectiveness of Adalimumab in ulcerative colitis. However, real-life data is scarce. We aimed to assess the effectiveness and predictive factors of effectiveness in a large Swedish cohort. Methods: Retrospective capture of data from local registries at five Swedish IBD centers. Clinical response and remission rates were assessed at three months after starting adalimumab treatment and patients were followed until colectomy or need for another biological. Bio-naive patients were compared to bio experienced patients. Factors associated with short term responses were assessed using logistic regression model. Failure on drug was assessed using a Cox proportional hazards regression model. Results: 118 patients (59 males, 59 females) with median age 34.4 years (IQR 27.0–51.4) were included. Median disease duration was 4.3 years (IQR 2.0–9.0) and follow-up 1.27 years (IQR 0.33–4.1). A clinical corticosteroid-free remission was achieved by 38/118 (32.2%) and response by 91/118 (77%) after three months. CRP >3 mg/l at baseline was predictive of short-term failure to reach corticosteroid-free remission. Factors associated with survival on the drug were male gender, CRP <3 mg/l and absence of primary sclerosing cholangitis. Patients >42 years of age at diagnosis were more likely to respond to adalimumab and remain on treatment compared to patients <20 years. Conclusions: An elevated CRP-level, primary sclerosing cholangitis and female gender were predictors of treatment failure. In contrast older age at diagnosis was a predictor of short-term clinical response and drug survival. Prior infliximab failure, regardless of cause, did not influence the outcome of adalimumab treatment.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: As the patents of originator biologics are expiring, biosimilar versions are becoming available for the treatment of inflammatory bowel disease (IBD). However, published switch studies of the first infliximab biosimilar, CT-P13, have delivered ambiguous results that could be interpreted as showing a trend towards inferior effectiveness in Crohn's disease (CD) compared with ulcerative colitis (UC). The aim of this study was to investigate the effectiveness and safety of switching IBD patients from treatment with Remicade to CT-P13.METHODS: In this prospective observational cohort study, all adult IBD patients on Remicade treatment, at four hospitals, were switched to CT-P13. The primary endpoint was change in clinical disease activity at 2, 6, and 12 months after the switch. Secondary endpoints were subgroup analyses of patients with and without concomitant immunomodulators; changes in biomarkers, quality of life, drug trough levels and anti-drug antibodies (ADAbs); and adverse events.RESULTS: A total of 313 IBD patients were switched (195 CD; 118 UC). There were no significant changes in clinical disease activity, quality of life, biomarkers (except a small but significant increase in albumin in CD) including F-calprotectin, drug trough levels, or proportion of patients in remission. Disease worsening rates were 14.0% for CD and 13.8% for UC; and 2.7% developed ADAbs and 2.2% developed serious adverse events.CONCLUSIONS: This is the largest study of switched IBD patients published to date, and it demonstrates that switching from Remicade to CT-P13 may be done with preserved therapeutic effectiveness and safety in both CD and UC.

Tidskriftsartikel (refereegranskat)abstract
- Immune checkpoint inhibitors (ICPI), such as ipilimumab [anti-cytotoxic T-lymphocyte antigen-4 (CTLA-4) antibody] and nivolumab or pembrolizumab [anti-programmed cell death protein-1 (PD-1) antibodies], improve survival in several cancer types. Since inhibition of CTLA-4 or PD-1 leads to non-selective activation of the immune system, immune-related adverse events (irAEs) are frequent. Enterocolitis is a common irAE, currently managed with corticosteroids and, if necessary, anti-tumor necrosis factor-α therapy. Such a regimen carries a risk of serious side-effects including infections, and may potentially imply impaired antitumor effects. Vedolizumab is an anti-integrin α4β7 antibody with gut-specific immunosuppressive effects, approved for Crohn’s disease and ulcerative colitis. We report a case series of seven patients with metastatic melanoma or lung cancer, treated with vedolizumab off-label for ipilimumab- or nivolumab-induced enterocolitis, from June 2014 through October 2016. Clinical, laboratory, endoscopic, and histologic data were analyzed. Patients initially received corticosteroids but were steroid-dependent and/or partially refractory. One patient was administered infliximab but was refractory. The median time from onset of enterocolitis to start of vedolizumab therapy was 79 days. Following vedolizumab therapy, all patients but one experienced steroid-free enterocolitis remission, with normalized fecal calprotectin. This was achieved after a median of 56 days from vedolizumab start, without any vedolizumab-related side-effects noted. The patient in whom vedolizumab was not successful, due to active ulcerative colitis, received vedolizumab prophylactically. This is the first case series to suggest that vedolizumab is an effective and well-tolerated therapeutic for steroid-dependent or partially refractory ICPI-induced enterocolitis. A larger prospective study to evaluate vedolizumab in this indication is warranted.

- No surveillance is recommended after radical excision of low-risk adenomas (pedunculated adenoma irrespective of size, sessile adenoma < or = 10 mm, number < or = 2. An endoscopic check-up is recommended 3-6 months after radical excision of high-risk adenomas (sessile adenoma > 10 mm, number > or = 3), as well as after excision of a pedunculated or a sessile adenoma with an unclear resection margin. All above is irrespective of histopathological adenoma classification. An endoscopic check-up is recommended 3 months after radical excision of a highly or moderately differentiated malignant polyp with no sign of invasion into blood or lymph vessels and with a maximum invasion depth stage T1-sm1. Surgical resection is necessary if the malignant polyp is poorly differentiated, and/or invades into blood or lymph vessels, and/or is stage T1-sm3, or is excised with unclear resection margins. Treatment for stage T1-sm2 polyps may be individualized. Individuals with low-risk adenomas and a first degree relative with colorectal cancer, individuals having high-risk adenomas or malignant polyps removed, as well as individuals operated on for colorectal cancer should be subjected to colonoscopy after three years and then every fifth year when < or = 75 years of age.

The cost-effectiveness of biological therapy cycles in the management of Crohn’s disease
- 2018
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Objectives: to examine the cost-effectiveness of continued treatment for patients with moderate-severe Crohn’s disease in clinical remission, with a combination of anti-TNFα (infliximab) and immunosuppressant therapy compared to two different withdrawal strategies (1) withdrawal of the anti-TNFα therapy, and (2) withdrawal of the immunosuppressant therapy, respectively. Material and methods: A decision-tree model (Markov type) was constructed mimicking three treatment arms: (1) continued combination therapy with infliximab and antimetabolites, (2) withdrawal of infliximab, or (3) withdrawal of the immunosuppressant. Relapses in each arm are managed with treatment intensification. State dependent relapse risks, remission probabilities and quality of life weights were collected from previous published studies. Results: Combination therapy was less costly and more efficient than the withdrawal of the immunosuppressant, and more costly and more efficient than withdrawal of infliximab. The incremental cost-effectiveness ratio for the combination therapy compared with withdrawal of infliximab was estimated at SEK 755 449 per additional QALY. This is well above the informal willingness-to-pay threshold in Sweden (500 000 SEK/QALY). The estimated cost-effectiveness of the combination therapy was found highly sensitive to the unit cost of infliximab; at a 36% lower unit cost of infliximab, the combination treatment would become cost-effective. The qualitative content of these results were quite robust to changes in the clinical effectiveness and the quality-of-life figures adopted in the calculations. The qualitative content of these results were quite robust to changes in the clinical effectiveness and quality-of-life values. Conclusions: Combination therapy using a combination of anti-TNFα (infliximab) and immunosuppressant is cost effective in the treatment of Crohn’s disease compared to treatment cycles in which the immunosuppressant is withdrawn. Combination treatment is not cost effective compared to treatment cycles in which infliximab is withdrawn, at current pharmaceutical prices.

- OBJECTIVES: To examine the cost-effectiveness of continued treatment for patients with moderate-severe Crohn's disease in clinical remission, with a combination of anti-tumour necrosis factor alpha [anti-TNFα] [infliximab] and immunomodulator therapy compared with two different withdrawal strategies: [1] withdrawal of the anti-TNFα therapy; and [2] withdrawal of the immunomodulator therapy, respectively. METHODS: A decision-tree model was constructed mimicking three treatment arms: [1] continued combination therapy with infliximab and immunomodulator; [2] withdrawal of infliximab; or [3] withdrawal of the immunomodulator. Relapses in each arm are managed with treatment intensification and re-institution of the de-escalated drug according to a prespecified algorithm. State-dependent relapse risks, remission probabilities, and quality of life weights were collected from previous published studies. RESULTS: Combination therapy was less costly and more efficient than the withdrawal of the immunomodulator, and more costly and more efficient than withdrawal of infliximab. Whether or not combination therapy is cost-effective, compared with the alternatives, depends primarily on current pharmaceutical prices and the willingness-to-pay per additional quality-adjusted life-year [QALY]. CONCLUSIONS: Combination therapy using a combination of anti-TNFα [infliximab] and an immunomodulator is cost-effective in the treatment of Crohn's disease compared with treatment cycles in which the immunomodulator is withdrawn. Combination treatment is cost-effective compared with treatment cycles in which infliximab is withdrawn, at prices of infliximab below€192/100 mg, given a willingness-to-pay threshold at€49 020 [Sweden] per additional QALY.
