In order to guide therapy in Ulcerative Colitis (UC),  repeated determination of intestinal inflammatory activity is essential. Endoscopy is the standard procedure to assess inflammation in UC. However innovative methods for non-invasive, uncomplicated and risk free estimation of inflammatory activity are needed as bowel preparation, patients discomfort and risk of procedural complications limit the (frequent) use of colonoscopy. Multispectral optoacoustic tomography (MSOT) is a promising new method to measure inflammation in UC. Using short and harmless impulses of NIR-lasers, it allows for determination of a specific hemoglobin-signal in the bowel-wall and therefore inflammatory activity in affected bowel segments. However, its informative value in UC has not been evaluated so far.

In 34 patients with confirmed UC, clinical activity parameters (e.g. clinical Mayo-Subscore, B-mode-sonography, C-reactive protein, white blood count) were collected and MSOT of the sigmoid was performed within 2 weeks before/after endoscopy. For MSOT, a commercially available clinical MSOT-system (Acuity Echo, iThera Medical, Munich) was used with sequential analysis of collected data on an external desktop PC. Finally, clinical data, ultrasound findings (Limberg) and MSOT-parameters (single wavelenghts 760 nm, 800 nm, 900 nm; multispectral signals hb, hbO2, hbT) were correlated with endoscopic findings (Mayo endoscopic Subscore, MES).

We found strong and significant correlation between MES and MSOT parameters 800 nm (Spearman r = 0,6599; p < 0,0001) and HbO2 (Spearman r = 0,6695; p < 0,0001), superior to sonographic evaluation of the inflammatory activity in affected bowel segments (Spearman r = 0,4914; p = 0,0023) . Simultaneously these MSOT parameters demonstrated excellent sensitivity and specifity in distinguishing moderately to highly active (MES 2,3) from inactive and mild disease (MES 0,1) (800nm: AUROC 0,9063 (p < 0,0001); sensitivity = 93,75 %, specificity = 88,89 %; HbO2: AUROC 0,9063 (p < 0,0001); sensitivity = 100 %, specificity = 88,89 %).

MSOT is a promising approach to non-invasively assess intestinal inflammation in UC and therefore monitor anti-inflammatory therapy in these patients. Further studies are required to validate these findings.

Inflammatory bowel diseases may lead to many non-neoplastic intestinal and extra-intestinal problems. 
The main intestinal complications comprise infections, obstruction, perforation fistulas etc, whereas the main extra-intestinal manifestations include skin conditions, liver and biliary diseases, eye complications, systemic infections and other systemic conditions.

Learning objectives: 
- which are the main non-neoplastic intestinal complications
- which are the main non-neoplastic extra-intestinal complications
- example and presentation of interesting histological cases

An increased rate of non epithelial neoplasm in IBD is described. They could be related to inflammation or to immunosuppressive treatment. The increased risk of infection related lymphomas in IBD is debated. Concerning non epithelial neoplasm related to immunosuppressive treatment they are mainly lymphomas, skin tumours and Kaposi’s sarcomas.

The main educational objective is to know and to  be aware about the presence of this rare entities.

The efficacy of risankizumab (RZB), an interleukin 23 p19 inhibitor, in patients with Crohn’s disease (CD) has been reported. Normalisation of high-sensitivity C-reactive protein (hs-CRP) and faecal calprotectin (FCP) are intermediate treatment targets in CD. Here, we evaluated changes in these objective inflammatory biomarkers and clinical outcomes with RZB treatment.

In 2 phase 3, randomised, double-blind studies (ADVANCE, NCT03105128; MOTIVATE, NCT03104413), patients with moderately to severely active CD received 12-week intravenous (IV) RZB induction therapy or placebo (PBO). Patients with clinical response to RZB IV induction were rerandomised in a 52-week maintenance study (FORTIFY, NCT03105102) to receive subcutaneous (SC) RZB or PBO (ie, RZB withdrawal). Induction analyses included patients who received either 600 mg RZB IV or PBO for 12 weeks. Maintenance analyses included patients who received 360 mg RZB SC every 8 weeks or withdrawal (PBO SC) for 52 weeks. Outcomes assessed were normalisation of hs-CRP and FCP concentrations at week 12 of induction and at week 52 of maintenance in patients with elevated biomarkers at baseline (hs-CRP > 5 mg/L and/or FCP > 250 μg/g), clinical biomarker response (defined as enhanced clinical response [≥ 60% average daily stool frequency (SF) decrease and/or ≥ 35% average daily abdominal pain score (APS) decrease] and ≥ 50% reduction in hs-CRP or FCP), and clinical biomarker remission (defined as clinical remission per CD Activity Index or SF/APS criteria and normal hs-CRP or FCP) during maintenance treatment. Nonresponder imputation was used for missing data.

Greater proportions of patients receiving RZB vs PBO achieved normalisation of hs‑CRP and FCP at the end of the 12-week induction period and the 52-week maintenance period (P < .0001 for all; Table). Among patients with clinical response to RZB IV induction and entered maintenance, rates of clinical biomarker response were maintained through week 52 in patients receiving 360 mg RZB SC and declined over time among patients in the withdrawal (PBO SC) arm (Figure A). Rates of clinical biomarker remission increased over time in patients receiving 360 mg RZB SC. At week 52, clinical remission and normalisation of hs‑CRP or FCP was achieved by 41% of patients receiving RZB vs 28%–29% of patients in the withdrawal (PBO SC) arm (Figure B-C). The safety profile of RZB in CD was previously reported.

Normalisation of objective biomarkers of inflammation in CD was achieved with RZB induction and maintenance therapy. Improvements in both clinical outcomes and biomarker levels were sustained with continuous RZB maintenance therapy and decreased over time in patients discontinuing RZB.

Educational objectives:
1) To understand the various definitions of malnutrition and how they related to clinical outcomes
2) To learn the various assessment techniques for determining malnutrition, including body composition analyses
3) To learn the emerging point-of-care assessment techniques that may improve clinical assessment and monitoring of malnutrition

Summary:
Malnutrition is very common in IBD patients, but historically, attention has been mostly placed on undernutrition.  It is becoming evident that overnutrition is increasing amongst the IBD population, with similar negative impacts on clinical outcomes.  This presentation will describe various definitions of malnutrition, including protein energy malnutrition, myopenia, sacropenia, myosteatosis, visceral obesity and micronutrient deficiencies and their relevance in predicting clinical outcomes.  Identification of such forms of malnutrition, such as use of imaging for body composition analyses, BMI, bioimpedance, handgrip devices and ultrasound will also be detailed.  In clinical practice, use of BMI has limited value and does not predict poor outcomes.  Nutritional assessment should encompass both detailed body composition analysis, often through imaging that IBD patients already undergo, and cheap, quick and easily applied point-of-care techniques to assess and monitor myopenia, sarcopenia are visceral adiposity.
