Quality of life in patients with moderate to severe ulcerative colitis and the impact of treatment: A narrative review.

As a chronic inflammatory disease, ulcerative colitis has significant negative impact on the quality of life (QoL) of patients. Since the disease affects many aspects of QoL, comprising multiple domains, treatments that induce and maintain remission can provide benefits beyond hard clinical endpoints. Effective treatment of ulcerative colitis can restore QoL and return it to normal or near normal levels. Biological therapies have shown consistent improvement in the QoL of patients with ulcerative colitis during the induction phase, with benefits that are generally maintained in the long-term. Current medical treatment options broadly comprise aminosalicylates, corticosteroids, thiopurines, and calcineurin inhibitors, as well as biologic therapies. Conventional therapies do not always adequately control disease in a sizeable portion of patients, while anti-TNF antibodies are associated with several issues such as contraindications, intolerance, primary non-response, and loss of response in some patients. JAK inhibitors have been associated with clinical improvements in disease manifestations and long-term improvement in QoL outcomes. However, additional studies are needed to better understand the comparative effects of different treatments on QoL and patient preferences for therapy. Herein, the available evidence is reviewed regarding the impact of various treatments on QoL in patients with moderate to severe ulcerative colitis

Update on the management of inflammatory bowel disease: specific role of adalimumab

Anti-tumor necrosis factor alpha (TNF-α) medications are a class of biologics employed in the treatment of patients with inflammatory bowel disease (IBD). Adalimumab is the first fully human monoclonal immunoglobulin directed against TNF-α, which binds with high affinity and specificity to membrane and soluble TNF. Adalimumab administered subcutaneously has demonstrated efficacy in the treatment of rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, and severe chronic psoriasis. Studies have shown that adalimumab is effective for inducing and maintaining remission of moderate-to-severe active Crohn’s disease (CD) patients at an induction dose of 160/80 mg (week 0 and 2) and at a maintenance dose of 40 mg every other week. The efficacy of adalimumab as a second-line therapy has also been documented for patients with loss of response or intolerance to infliximab. Adalimumab is also superior to placebo for inducing and maintaining complete perianal fistula closure. It also seems effective for reducing extraintestinal manifestations. The safety profile is similar to that of other anti-TNF therapy in CD patients, with lower immunogenicity and rate of adverse injection reactions than infliximab. Adalimumab is not approved for the treatment of ulcerative colitis (UC). Recently, however, the results of the first randomized, controlled trial on adalimumab for UC showed that adalimumab at 160/80 mg induction dose was safe and effective for inducing remission and clinical response after 8 weeks in patients with moderately-to-severely active UC failing treatment with corticosteroids and/or immunosuppressants. More data are necessary to clarify the therapeutic role of adalimumab in UC. This review of the literature summarizes available data on the efficacy and safety profile adalimumab in patients with IBD

Enhancing treatment success in inflammatory bowel disease: Optimising the use of anti-TNF agents and utilising their biosimilars in clinical practice.

Abstract Anti-tumour necrosis factor (TNF) agents such as infliximab and adalimumab have greatly altered the treatment landscape in inflammatory bowel disease (IBD). However, there are remaining unmet needs and opportunities to optimise their use. Recent data suggest that proactive therapeutic drug monitoring may lead to more efficient usage of these agents, with potential for higher rates of corticosteroid-free clinical remission than with reactive monitoring. Expanded application of faecal calprotectin measurements may also be valuable, given the ease of use of the assay and its proven effectiveness as a diagnostic tool and predictor of relapse risk. From a practical viewpoint, improved multidisciplinary working may be essential to optimise patient care, with IBD nurse specialists playing an increasingly central role within this model. Finally, the availability of biosimilars of the anti-TNF agents allow drug costs to be reduced without compromising safety or efficacy – thereby providing opportunities to improve accessibility. Alongside extensive data on originator to biosimilar infliximab switch, new studies are beginning to demonstrate the safety of biosimilar to biosimilar switch, as well as adalimumab biosimilar transitions. The risk of a nocebo effect when switching to a biosimilar can be reduced through improved patient education and preparation

Higher risk of tuberculosis reactivation when anti-TNF is combined with immunosuppressive agents. A systematic review of randomized controlled trials

Objective. Treatment with tumour necrosis factor antagonists (anti-TNF) has been recognized as a risk factor for tuberculosis (TB) reactivation. Our aim was to evaluate risk of TB reactivation in rheumatologic and non-rheumatologic diseases treated with the same anti-TNF agents with and without concomitant therapies. Methods. We searched for randomized controlled trials (RCTs) evaluating infliximab, adalimumab, and certolizumab in both rheumatologic and non-rheumatologic diseases until 2012. Results were calculated as pooled rates and/or pooled odd ratios (OR). Results. Overall, 40 RCTs with a total of 14,683 patients (anti-TNF: 10,010; placebo: 4673) were included. TB reactivation was 0.26% (26/10,010) in the anti-TNF group and 0% (0/4673) in the control group, corresponding to an OR of 24.8 (95% CI 2.4-133). TB risk was higher when anti-TNF agents were combined with methotrexate or azathioprine as compared with either controls (24/4241 versus 0/4673; OR 54; 95% CI 5.3-88) or anti-TNF monotherapy (24/4241 versus 2/5769; OR 13.3; 95% CI 3.7-100). When anti-TNF was used as monotherapy, TB risk tended to be higher than placebo (2/5769 versus 0/4673; OR 4; 95% CI 0.2-15.7). Conclusions. TB risk with anti-TNF agents appeared to be increased when these agents were used in combination with methotrexate or azathioprine as compared with monotherapy regimen. TB risk seemed to be higher than placebo, even when monotherapy is prescribed

Role of HMGB1 as a suitable biomarker of subclinical intestinal inflammation and mucosal healing in patients with inflammatory bowel disease

BACKGROUND: Noninvasive biomarkers of high- and low-grade intestinal inflammation and of mucosal healing (MH) in patients with inflammatory bowel disease are currently lacking. We have recently shown that fecal high mobility group box 1 (HMGB1) protein is a novel biomarker of gut inflammation. We aimed at investigating in a mouse model if HMGB1 was able to foresee both a clinically evident and a subclinical gut inflammation and if its normalization indicated MH. We also aimed at confirming the results in patients with Crohn's disease (CD) and ulcerative colitis. METHODS: C57BL6/J mice were treated with increasing doses of dextran sodium sulphate to induce colitis of different severity degrees; 28 with CD, 23 with ulcerative colitis, and 17 controls were also enrolled. Fecal HMGB1 was analyzed by enzyme-linked immunosorbent assay and immunoblotting. RESULTS: Fecal HMGB1 increased by 5-, 11-, 18-, and 24-folds with dextran sodium sulphate doses of 0.25%, 0.50%, 1%, and 4%, respectively, showing that the protein detected a high-grade and a subclinical inflammation. After a recovery time of 4-week posttreatment, HMGB1 returned to control levels, paralleling MH. In patients, fecal HMGB1 significantly correlated with endoscopic indexes (Simple Endoscopic Score for Crohn's Disease [SES-CD], endoscopic Mayo subscore), but not with the disease activity indexes (Crohn's disease Activity Index, partial Mayo score). CONCLUSIONS: Fecal HMGB1 is a robust noninvasive biomarker of clinically overt and subclinical gut inflammation; it can also be a surrogate marker of MH. We suggest the use of fecal HMGB1 to monitor the disease course and assess therapy outcomes in inflammatory bowel diseaseBACKGROUND: Noninvasive biomarkers of high- and low-grade intestinal inflammation and of mucosal healing (MH) in patients with inflammatory bowel disease are currently lacking.

Timing of proper introduction, optimization and maintenance of anti-TNF therapy in IBD: Results from a Delphi consensus

Background: Crohn's disease and ulcerative colitis are inflammatory bowel diseases (IBDs) with a rapidly growing worldwide incidence. The last decades presented rapid progress in pharmacological treatment leading in many cases to clinical and endoscopic remission, including biological treatment with anti-TNF agents. Aim: The exact timing of introduction, optimization and maintenance of anti-TNF therapy in IBDs is not thoroughly covered in current guidelines. Methods: We used the Delphi panel methodology to gather the IBD experts' views and achieve consensus for clinical recommendations on introducing and maintaining anti-TNF therapy for patients with IBDs. Results: Twelve recommendations achieved a high level of consensus in two assessment rounds by 52 (1st round) and 47 (2nd round) IBD experts. Conclusion: In many clinical situations, the early use of anti-TNF therapy is recommended. Nowadays, the cost-efficacy profile of anti-TNF biosimilars makes them the first-line drug in a substantial proportion of patients, thus providing the opportunity to increase access to biological therapy

Use of biologics for the management of Crohn's disease: IG-IBD clinical guidelines based on the GRADE methodology

A cure for Crohn's disease (CD), a chronic inflammatory disease of the gastrointestinal tract of unknown etiology, is not available, so patients require lifelong management to keep inflammation under control. The therapeutic armamentarium has expanded with approval of several biological drugs, including in-fliximab, adalimumab, vedolizumab and ustekinumab - monoclonal antibodies that target different in-flammatory pathways - and darvadstrocel, a suspension of expanded human allogeneic, adipose-derived, mesenchymal stromal cells for the treatment of refractory complex perianal fistula. Notwithstanding ex-isting practice guidelines on medical therapy for CD, the Italian Group for the Study of Inflammatory Bowel Disease felt the need to issue new guidelines focused on the use of biologics for managing the intestinal manifestations of CD and based on the GRADE methodology. This document presents recom-mendations regarding six clinical settings, from the induction to the maintenance of clinical remission, and from optimization and de-escalation of treatments to dealing with perianal CD and post-operative recurrence. The 19 evidence-based statements are supported by information on the quality of the evi-dence, agreement rate among panel members, and panel comments mainly based on evidence from real world studies

tofacitinib treatment is associated with modest and reversible increases in serum lipids in patients with ulcerative colitis

Background & Aims Tofacitinib is an oral, small-molecule Janus kinase inhibitor for the treatment of ulcerative colitis (UC). We analyzed inflammation, lipid concentrations, and incidence rates of major adverse cardiovascular (CV) events (MACEs) in patients who received tofacitinib in worldwide studies. Methods We collected data from 1157 patients who participated in 3 8-week induction studies (1 phase-2 study and 2 phase-3 studies; patients received tofacitinib 10 mg twice daily or placebo), a 52-week phase-3 maintenance study of responders (patients received tofacitinib 5 or 10 mg twice daily or placebo), and an ongoing long-term extension study of patients who did and did not respond to induction or maintenance therapy (patients received tofacitinib 5 or 10 mg twice daily). Lipid concentrations were assessed from induction baseline to week 61 (week 52 of maintenance therapy). We calculated MACE incidence rates (patients with ≥1 event per 100 patient-years of exposure) and Reynolds risk score (RRS; a composite score used to determine CV risk) for patients given tofacitinib vs placebo. Results The mean RRS was P Conclusions In an analysis of data from 5 trials of patients with UC who received tofacitinib, we found reversible increases in lipids with treatment and inverse correlations with reduced levels of high-sensitivity C-reactive protein. We did not find clinically meaningful changes in lipid ratios or RRS. MACEs were infrequent and not dose-related.
