Objectives. Mucosal healing has become the new goal of treatment in ulcerative colitis. Fecal calprotectin has been demonstrated to differentiate between mucosal inflammation and mucosal healing. With this project, we investigated whether a reduction in f-calprotectin to <250 μg/g after medical treatment for active ulcerative colitis could predict mucosal healing. Material and Methods. After a baseline colonoscopy, 20 patients with active ulcerative colitis were followed with consecutive fecal calprotectin monthly until two measurements of fecal calprotectin < 250 μg/g or a maximum follow-up of 12 months. A flexible sigmoidoscopy was then performed and Mayo endoscopic subscore was used to evaluate degree of inflammation. Simple Clinical Colitis Activity Index was used for evaluation of clinical disease activity. Results. A total of 16 patients achieved fecal calprotectin < 250 μg/g during follow-up, and all 16 patients had endoscopic mucosal healing (Mayo endoscopic subscore of ≤1) on the second endoscopy. The remaining four patients had persistently high f-calprotectin levels before the second endoscopy with Mayo endoscopic subscore corresponding to endoscopic mucosal healing in three out of four patients. Conclusions. Fecal calprotectin <250 μg/g after medical treatment for active ulcerative colitis is a reliable marker of endoscopic mucosal healing.

Mucosal healing (MH) is the main therapeutic goal of Crohn’s disease (CD). The Mucosal Inflammation Noninvasive Index (MINI) appears to be a promising tool for distinguishing MH from its inflammation. This study aims to evaluate MINI in monitoring remissions induced by exclusive enteral nutrition (EEN) in pediatric CD patients. Out of 55 newly diagnosed CD children, 31 who completed 6–8 weeks of EEN were analyzed. Clinical and biochemical data, activity of CD assessed with the Pediatric Crohn’s Disease Activity Index (PCDAI) and MINI were compared within seven days pre- and post-EEN. Response to induction therapy was defined as a decrease of PCDAI by >12.5 points. The follow-up was performed up to 12 months after EEN termination. Out of 31 children who completed 6–8 weeks of EEN, eight required corticosteroids in addition to EEN. Twenty-four patients (77%) responded to induction therapy. In responders, MINI decreased from 19 (Q1:17; Q3:22) to 12 (Q1:6; Q3:14), p < 0.001. The diagnostic accuracy of post-EEN MINI and post-EEN fecal calprotectin (FC) for treatment failure were AUC: 0.899 (95%CI: 0.737–1.000) and 0.762 (95%CI: 0.570–0.954), respectively. In the follow-up of 25 patients (80.6%), the post-EEN MINI of ≥13 points predicted CD relapse (87.5% sensitivity; 64.7% specificity), while FC had no prognostic value. MINI allows for monitoring of EEN and is superior in predicting disease relapse to FC.

Abstract Background Submucosal fibrosis in ulcerative colitis (UC) has been associated with disease severity in colectomy specimens. As intestinal ultrasound (IUS) visualizes all individual wall layers, we aimed to evaluate baseline IUS features to determine endoscopic response and investigate changes in wall layers during anti-inflammatory treatment in patients with UC Methods Moderate-severe UC patients (endoscopic Mayo score (EMS)≥2) extending beyond the rectum starting treatment were included. Simple Clinical Colitis Activity Index (SCCAI), fecal calprotectin (FCP), IUS and endoscopy were performed at baseline and at follow-up between week 8 and 26. BWT, individual wall layer thickness (WT) (mucosa (MC), submucosa (SM) and muscularis propria (MP)) and ratios among layers, Colour Doppler Signal, loss of haustrations, loss of stratification and hyperechogenicity of the submucosa (HoS) (Figure 1) were scored for the sigmoid colon (SC). EMS was assessed for the SC: endoscopic remission (ER) was defined as EMS=0 and endoscopic improvement (EI) as EMS≤1. For statistical analysis a paired t-test and X2-test were used. Results 49 patients were included of whom 61% failed ≥1 biological. 59% started tofacitinib and 41% started a biological. At follow-up, 30% and 49% reached ER and EI, respectively. BWT decreased significantly when ER (2.32 ± 1.63 mm vs 1.00 ± 1.98 mm, p=0.034) or EI (2.53 ± 1.66 mm vs 0.30 ± 1.58 mm, p&lt;0.0001) was reached. In patients with ER and EI, the SM thickness showed significantly more pronounced decrease compared to the other wall layers (Table 1 and Figure 2). Baseline presence of HoS (29% of patients) predicted failure of treatment (ER: OR: 0.10, 95% CI: 0.01-0.87, p=0.014, EI: OR: 0.16, 95% CI: 0.04-0.65, p=0.008,). Furthermore, when HoS was present, SCCAI (7.33 ± 3.62 vs 9.75 ± 3.23, p=0.023) and FCP (1249 ± 903 µg/g vs 2494 ± 2277 µg/g, p=0.008) were significantly lower at baseline. Also, patients with HoS more frequently failed one (OR: 4.44, 95% CI: 1.08-18.32, p=0.03) or multiple biologicals (OR: 5.63, 95% CI: 1.54-20.52, p=0.009). However, disease duration (p=0.950) or age at onset (p=0.853) did not differ between groups. Conclusion This is the first study showing that HoS on IUS is a predictor of endoscopic non-response to biologicals and tofacitinib in patients with UC. Additionally, changes in SM layer thickness is the most important component of the total bowel wall when evaluating mucosal healing on IUS.

Purpose. Few reports have compared the clinical efficacy of a pH-dependent release formulation of mesalazine (pH-5-ASA) with a time-dependent release formulation (time-5-ASA). We examined whether pH-5-ASA is effective for active ulcerative colitis (UC) in patients resistant to time-5-ASA.Methods. We retrospectively and prospectively analyzed the efficacy of pH-5-ASA in mildly to moderately active UC patients in whom time-5-ASA did not successfully induce or maintain remission. The clinical efficacy of pH-5-ASA was assessed by clinical activity index (CAI) before and after switching from time-5-ASA. In addition, the efficacy of pH-5-ASA on mucosal healing (MH) was evaluated in a prospective manner by measuring fecal calprotectin concentration.Results. Thirty patients were analyzed in a retrospective manner. CAI was significantly reduced at both 4 and 8 weeks after switching to pH-5-ASA. In the prospective study (n=14), administration of pH-5-ASA also significantly reduced CAI scores at 4 and 8 weeks in these patients who were resistant to time-5-ASA. In addition, fecal calprotectin concentration was significantly decreased along with improvement in CAI after switching to pH-5-ASA.Conclusions. Our results suggest that pH-5-ASA has clinical efficacy for mildly to moderately active patients with UC in whom time-5-ASA did not successfully induce or maintain remission.

Abstract Background Pediatric ulcerative colitis (UC) is characterized by low sustained remission rates and frequent extension of disease even if clinical remission is obtained with therapy. Moderate to severe endoscopic activity is a risk factor for relapse while evidence regarding early mucosal healing or persistence of inflammation after remission in children is not available. Our aim was to evaluate if persistence of significant inflammation is common and could explain the high relapse rate in pediatric UC. Methods Pediatric UC patients with clinical remission, defined as pediatric UC activity index (PUCAI) scores &lt; 10, were prospectively assessed for mucosal healing by endoscopy 3–5 months after remission was documented. Mayo score was assessed for each segment by a blinded adult gastroenterologist using central reading. Symptomatic patients prior to sigmoidoscopy were excluded Sustained remission was assessed retrospectively at 18 months follow-up. Results Forty-six children were enrolled, 28 children in continuous clinical remission at time of sigmoidoscopy were included in the final analysis. Mayo 0 was present in 12/28 (42.86%), Mayo 1 in 2/28 (7.1%) and Mayo 2–3 in 14/28 (50.0%) endoscopies. Among 23/28 patients with follow-up through 18 months, remission was sustained in 2/11 (18.18%) of patients with Mayo 2 and 3 versus 6/12 (50.0%) with Mayo score 0–1. Conclusion Over 50% of children assessed for mucosal healing 3–5 months after clinical remission is obtained have residual disease activity, primarily moderate to severe inflammation which was associated with lower sustained remission. Early sigmoidoscopy after clinical remission for assessment of mucosal disease should be considered in pediatric UC.

Assessment Of Disease Activity

Abstract Background Optimal management of patients with ulcerative colitis (UC) requires the accurate assessment of disease activity. Endoscopic evaluation is considered the gold standard approach, but it is invasive. We aimed to determine how strong patient reported outcomes, clinical scores and symptoms correlate with endoscopy for assessment of disease activity in UC patients. Methods 171 patients were included prospectively and consecutively (age: 49 (IQR: 38-61) years, duration 12 (4-19)years, 79 females (46.2%), 57.3% extensive disease, 42.7% on biologicals) at the time of the colonoscopy. The 2 item patient reported outcome (PRO), partial MAYO, Simple Clinical Colitis Activity Index (SCCAI), Mayo endoscopic subscore (MES), Baron and Ulcerative Colitis Endoscopic Index of Severity (UCEIS) scores were calculated. C reactive Protein (CRP) and fecal calprotectin (FCAL) was available in 83 and 45.6% of patients. 17.0% had clinical flare, treatment was escalated in 14.6% of patients. Sensitivity, specificity, PPV and NPV values were calculated, ROC analysis and K-statistics were performed. Results Rectal bleeding (RBS), stool frequency (SF) subscore of 0, or total PRO2 remission (RBS 0 and SF ≤1), partial MAYO (≤2) and SCCAI (≤2.5) remission were similarly associated to mucosal healing defined by MES (0 or ≤1) or Baron (0 or ≤1) scores (Table 1). PRO2 (AUCMES0/Baron0: 0.770/0.740, AUCMES0-1/Baron0-1: 0.868/0.858), SF (AUCMES0/Baron0:0.751/0.724, AUCMES0-1/Baron0-1:0842/0.820), RBS (AUCMES0/Baron0: 0.718/0.698, AUCMES0-1/Baron0-1: 0.814/0.845) partial Mayo (AUCMES0/Baron0: 0.823/0.788, AUCMES0-1/Baron0-1: 0.927/0.902) and SCCAI (AUCMES0/Baron0: 0.767/0.752, AUCMES0-1/Baron0-1:0.888/0.867) were similarly associated with mucosal healing in a ROC analysis. There was a strict association between MES 0 and Baron 0 (k=0.917) and UCEIS &lt;4 and MES 0-1 (k=0.813), while moderate to fair agreement between UCEIS &lt;4 and MES 0 (K=0.471) or Baron 0 (K=0.414)/Baron 0-1 (K=0.353), and between MES 0-1 and Baron 0-1 (K= 0.350) scores. Agreement between CRP and clinical remission or endoscopic healing (MES/Baron) was poor (K~0.2), while agreement between FCAL (&gt;100 or &gt;250) and RBS-PRO2 remission (K&gt;100 or &gt;250: 0.44-0.60) or pMAYO (K&gt;100 or &gt;250: 0.41-0.59) or MES/Baron 0 was moderate to good (K&gt;100:0.53-0.52 and K&gt;250:0.57-0.53). Conclusion We found no difference across accuracy of RBS, SF, PRO2, partial Mayo and SCCAI in predicting endoscopic healing. A strong association was found with high PPV for MES/Baron ≤1 and high NPV for MES/Baron 0. FCAL, but not CRP was associated to clinical and endoscopic remission.

Abstract Background In ulcerative colitis (UC) patients who have achieved mucosal healing, active microscopic colonic mucosal inflammation is commonly observed. We aimed to assess the association between histological activity and disease relapse in endoscopically quiescent UC. Methods Ulcerative colitis patients with endoscopically quiescent disease and ≥12 months of follow-up were included. Biopsies were reviewed for the presence of basal plasmacytosis (BPC) and active histological inflammation, defined as a Geboes score (GS) ≥3.2. Primary outcome measures were disease relapse at 18 months and time to first relapse after index colonoscopy. Results Seventy-six UC patients (51% male; mean age, 38.6 years; median follow-up [range], 75.2 [2–118] months) were included. Sixty-two percent had an endoscopic Mayo score of 0 at index colonoscopy. Basal plasmacytosis was present in 46% and active histological inflammation in 30% of subjects. Presence of BPC was associated with a significantly shorter time to disease relapse (P = 0.01). Active histological inflammation was significantly associated with clinical relapse at 18 months (P = 0.0005) and shorter time to clinical relapse (P = 0.0006). Multivariate analysis demonstrated active histological inflammation to be independently associated with clinical relapse at 18 months and time to clinical relapse. Conclusions In endoscopically quiescent UC, active histological inflammation and the presence of BPC are adjunctive histological markers associated with increased likelihood of disease relapse. Although prospective studies are required, the presence of these histological markers should be a factor considered when making therapeutic decisions in UC.

Abstract Background Infliximab pharmacokinetics in steroid-refractory [SR] ulcerative colitis [UC] suggest a need for higher dosing, but data concerning efficacy of intensification in this setting are lacking in children and inconsistent overall. Methods Paediatric patients [N = 125] treated with infliximab for SR or steroid-dependent UC were retrospectively reviewed. Outcomes [clinical response and remission, colectomy, mucosal healing, safety] with standard vs intensified induction [mean induction dose ≥7 mg/kg or interval ≤5 weeks between doses 1 and 3] were compared. Results Among 125 patients [median age 14 years, median UC duration 0.7 years, 74 SR], 73 [58%] received standard induction and 52 [42%] received intensified induction. Overall, 73 [58%] achieved remission (judged by physician global assessment [PGA] and paediatric UC activity index [PUCAI]≤10]. Among patients in remission, 7 [10%] experienced secondary loss of response by a median of 0.7 [IQR 0.4–1.0] years. Of the 74 SR patients, 17 [23%] underwent colectomy, and of the 51 steroid-dependent patients, 12 [24%] underwent colectomy. Intensified induction in SR patients was associated with a higher chance of remission (hazard ratio [HR] 3.2, p = 0.02) and a lower chance of colectomy [HR 0.4, p = 0.05], but did not improve outcomes in steroid-dependent patients. During follow-up, 46/73 [63%] patients in remission had regimen individualization, with similar rates of return to standard dosing after 1 year between those with initial intensified or standard induction. Follow-up endoscopy, performed in 35/73 patients in remission, demonstrated mucosal healing for 66%. Adverse events were rare, despite use of intensified regimens. Conclusions These data suggest a benefit from intensified infliximab induction specifically among children with steroid-refractory UC. Prospective studies comparing dosing regimens and incorporating therapeutic drug monitoring should be undertaken.

Background & Aims: Golimumab (GOL) has been recently approved in Italy for the treatment of ulcerative colitis (UC) unresponsive to standard treatments. Our aims were to assess the real-life efficacy and safety of GOL in managing UC outpatients in Italian primary Inflammatory Bowel Diseases (IBD) centres.Methods: Consecutive UC outpatients with at least 3-months follow-up were enrolled. Primary end-point was the induction and maintenance of remission in UC, defined as Mayo score ≤2, at 6-month follow-up.Results: Ninety-three patients were enrolled. At 6-month follow-up, remission was obtained in 34 (36.5%) patients. Shorter duration of disease was the only significant predictive factor of remission. Clinical response was achieved in 60 (64.5%) patients, while mucosal healing (MH) was obtained in 18 (19.3%) patients. Sixteen (47.0%) patients under remission were still under therapy with steroids. C-reactive protein and fecal calprotectin significantly dropped during the follow-up (p<0.001 for both proteins). Adverse events occurred in 4 (4.3%) patients and 3 of them stopped treatment. Colectomy was performed in only one patient (1.1%).Conclusions: Golimumab seems to be safe and effective in inducing and maintaining remission in real life UC outpatients.Abbreviations: ADA: Adalimumab; CRP: C-reactive Protein; GOL: Golimumab; FC: Fecal calprotectin; IBD: Inflammatory Bowel Diseases; IFX: Infliximab; IQR: Interquartile range; MH: Mucosal Healing; SC: Subcutaneously; TBC: Tuberculosis; TNFα: Tumor necrosis factor α; UC: Ulcerative Colitis.
