Background: Inflammatory bowel diseases (IBDs), including ulcerative colitis (UC) and Crohn’s disease (CD), are chronic and disabling diseases that affect patient health-related quality of life (HRQoL). IBD patients are frequently exposed to high levels of stress and psychological distress. Biological drugs have been proven to reduce inflammation, hospitalization, and most of the complications that characterize IBDs; their potential contribution to patients’ HRQoL remains to be explored. Aim: To evaluate and compare any change in the HRQoL and markers of inflammation in IBD patients undergoing biological drugs (infliximab or vedolizumab). Material and Methods: A prospective observational study was conducted on a cohort of IBD patients, aged >18 years, who were prescribed with infliximab or vedolizumab. Demographic and disease-related data at baseline were collected. Standard hematological and clinical biochemistry parameters, including C-reactive protein (CRP), white blood cells count (WBC), erythrocytes sedimentation rate (ESR), and α1 and α2 globulins were measured after a 12-h fast at baseline (T0), after 6 weeks (T1), and at 14 weeks (T2) of biological treatment. Steroid use, disease activity as measured by the Harvey–Bradshaw index (HBI) and partial Mayo score (pMS) for the CD and UC, respectively, were also recorded at each timepoint. The Short Form 36 Health Survey (SF-36), Functional Assessment of Chronic Illness Therapy (FACIT-F), and Work Productivity and Activity Impairment–General Health Questionnaire (WPAI:GH) were administered to each patient at baseline, T1, and T2 to address the study aims. Results: Fifty eligible consecutive patients (52% with CD and 48% with UC) were included in the study. Twenty-two patients received infliximab and twenty-eight received vedolizumab. We noted a significant reduction in the CRP, WBC, α1, and α2 globulins from T0 to T2 (p = 0.046, p = 0.002, p = 0.008, and p = 0.002, respectively). Participants showed a significant decrease in steroid administration during the observation period. A significant reduction in the HBI of CD patients at all three timepoints and a similarly significant decrease in the pMS of UC patients from baseline to T1 were recorded. Statistically significant changes were observed in all questionnaires during follow-up as well as an overall improvement in the HRQoL. The interdependence analysis carried out between the biomarkers and the scores of the individual subscales showed a significant correlation between the variation (Δ) of the CRP, Hb, MCH, and MCV with physical and emotional dimensions of the SF-36 and FACIT-F tools; work productivity loss expressed by some of the WPAI:GH items negatively correlated with the ΔWBC and positively with the ΔMCV, ΔMCH, and Δ α1 globulins. A sub-analysis according to the type of treatment showed that patients receiving infliximab experienced a more pronounced improvement in their HRQoL (according to both SF-36 and FACIT-F) compared with patients receiving vedolizumab. Conclusions: Both infliximab and vedolizumab played an important role in contributing to the improvement of the HRQoL in IBD patients by also reducing inflammation and, consequently, steroid use in patients with an active disease. HRQoL, being one of the treatment goals, should also be assessed when taking charge of IBD patients to assess their clinical response and remission. The specific correlation between the biomarkers of inflammation and life’s spheres, as well as their possible role as clinical markers of HRQoL, should be further investigated.

Background and Aim Monitoring mucosal inflammation in inflammatory bowel disease (IBD) is of major importance to prevent complications and improve long-term disease outcome. The correlation of clinical activity indices with endoscopic disease activity is, however, moderate. Fecal calprotectin (FC) is a better predictor of mucosal inflammation, but values between 100 and 250 µg/g are difficult to interpret in clinical practice. We aimed to evaluate the occurrence of indefinite FC levels in a real-life IBD cohort and study the additional value of a combination of biochemical markers and clinical activity indices. Methods In total, 148 Crohn’s disease (CD) and 80 ulcerative colitis (UC) patients visiting the outpatient clinic were enrolled. FC, clinical disease activity scored by the Harvey–Bradshaw index or Simple Clinical Colitis Activity Index, and C-reactive protein (CRP) were assessed. In a subset of patients, endoscopic activity was scored by the simple endoscopic score-Crohn’s disease and Mayo endoscopic subscore. Clinical activity index, CRP, and FC were integrated in a combination score and compared with endoscopy. Results Indefinite FC values were present in 24% of CD and 15% of UC. In the cohort of patients with endoscopy scores available, the combination score predicted endoscopic disease activity in CD with a sensitivity of 83% and specificity of 69% [positive predictive value (PPV) 58%, negative predictive value (NPV) 89%]. In UC, this was 88 and 75% (PPV 93%, NPV 60%). Conclusions A combination of FC with clinical activity indices or CRP may aid in classifying patients with indefinite disease activity according to FC alone.

International audience; Mucosal healing (MH) is now considered as a major treatment goal in clinical trials and clinical practice for patients with inflammatory bowel disease (IBD). MH is associated with sustained clinical remission, steroid-free remission, and reduced rates of hospitalization and surgery. There is a well-known disconnect between clinical symptoms and mucosal lesions that is more pronounced in CD. More stringent therapeutic goals have been discussed recently such as deep remission defined as clinical remission associated with MH. Recent international guidelines from the IOIBD recommended deep remission as a treatment goal in clinical practice. However there is no validated definition of deep remission in IBD. Also, the efficacy of available drugs to induce and maintain deep remission in IBD is poorly known. Finally, whether deep remission is the best way to modify the course of IBD and whether it should be achieved before considering drug de-escalation have to be formally evaluated in upcoming disease-modification trials.

International audience; Inflammatory bowel diseases (IBD) are chronic and disabling conditions. Accumulating evidence indicates that we need to look beyond clinical symptoms as current therapeutic strategies have not modified the course of IBD. Therapeutic goals for IBD have evolved from a mere control of symptoms to mucosal healing (MH). Achieving deep remission (clinical remission, biomarker remission and MH) might be the only way to alter disease course in IBD patients. In Crohn’s disease (CD), deep remission has been recently defined as Crohn’s Disease Activity Index

In the past decade, thanks to the introduction of biologic therapies, a new therapeutic goal, mucosal healing (MH), has been introduced. MH is the expression of an arrest of disease progression, resulting in minor hospitalizations, surgeries, and prolonged clinical remission. MH may be achieved with several therapeutic strategies reaching success rates up to 80% for both, ulcerative colitis (UC) and Crohn's disease (CD). Various scoring systems for UC and for the transmural CD, have been proposed to standardize the definition of MH. Several attempts have been undertaken to de-escalate therapy once MH is achieved, thus, reducing the risk of adverse events. In this review, we analysed the available studies regarding the achievement of MH and the subsequent treatment de-escalation according to disease type and administered therapy, together with non-invasive markers proposed as predictors for relapse. The available data are not encouraging since de-escalation after the achievement of MH is followed by a high number of clinical relapses reaching up to 50% within one year. Unclear is also another question, in case of combination therapies, which drug is more appropriate to stop, in order to guarantee a durable remission. Predictors of unfavourable outcome such as disease extension, perianal disease, or early onset disease appear to be inadequate to foresee behaviour of disease. Further studies are warranted to investigate the role of histologic healing for the further course of disease.

Objective This article investigates the methods of achieving deep remission of inflammatory bowel disease (IBD). Methods Increasing recognition of the concept of quality of care is contributing to the evolution of treatment goals in patients with IBD from clinical response and remission (symptom control) toward deep remission. A change in the treatment goal requires a change in the treatment strategy. Optimization of conventional therapy, early treatment, use of the Lemann score, performance of double-balloon endoscopy, treatment using Traditional Chinese Medicine, and good communication between physicians and patients are needed to attain deep remission. Results The above-mentioned methods can help to achieve deep remission. Conclusion Using the above methods, it will be possible to improve the prognoses of patients with IBD by minimizing complications and bowel damage and thereby changing the course of the disease.
