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 5-ASA is a key drug to treat the patients with mild-to-moderate ulcerative colitis (UC). Probiotics is sometimes used to UC patients for the purpose to correct dysbiosis of intestine. In theory, the efficacy of 5-ASA, especially pH-dependent release formulation of mesalazine may be weakened by the co-treatment with probiotics because of its effect leading to acidic condition in large intestine. However, the detail analysis about UC patients treating with 5-ASA and probiotics has not been elucidated. In the present study, we demonstrated the clinical course of UC patients treated by 5-ASA with probiotics to investigate the effect of probiotics to 5-ASA treatment. Methods The subjects were 85 UC patients who were in clinical remission and taking 5-ASA at the hospital of Kyoto Prefectural University of Medicine from January to March 2014. The clinical characteristics (age, sex, clinical activity index, disease location, and type of 5-ASA) and the rate of relapse until October 2019 were compared between probiotics group and no probiotics group. Furthermore, the rates of relapse were analysed for each specific 5-ASA between probiotics user and no probiotics user. The clinical activity index (CAI) was determined using Lichtiger index. The relapse of UC is defined by the increase of CAI, additional medication for UC, and endoscopic deterioration of colonic mucosa. Results Patients were included 39 cases in probiotics group and 46 cases in no probiotics group. There was no significant difference between probiotics and no probiotics group on the average age (53.1 ± 16.8 vs. 51.3 ± 14.2 years old, p = 0.59), the rate of male gender (41.0% vs. 41.3%, p =0.97), the average CAI (2.1 ± 0.64 vs. 2.0 ± 0.73, p = 0.59), disease location (extensive/left/rectum: 20/7/12 vs. 21/10/15 cases, p = 0.31), and type of 5-ASA (salazosulfapyridine/time-dependent mesalazine/pH-dependent mesalazine: 5/18/16 vs. 6/18/22 cases, p = 0.46). Besides, there was no significant difference between probiotics group and no probiotics group (51.3% vs. 52.2%, p = 0.93) about the rate of relapse. Regarding each specific 5-ASA usage, there was no significant difference on salazosulfapyridine (40.0% vs. 33.3%, p = 1), time-dependent mesalazine (44.4% vs. 50.0%, p = 1), and pH-dependent mesalazine (62.5% vs. 59.1%, p = 0.90) between probiotics user and no probiotics user. Conclusion In the present study, the co-treatment with probiotics did not affect the relapse with UC patients regardless the type of 5-ASA, suggesting that the usage of probiotics might not disturb the efficacy of 5-ASA for UC patients.

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.

IBD98-M is a delayed-release formulation of mesalamine (mesalazine) and SH with a potential therapeutic role in ulcerative colitis (UC). A total of 51 patients with a modified Ulcerative Colitis Disease Activity Index (UCDAI) score of ≥4 and ≤10, and a modified UCDAI endoscopy subscore ≥1 were randomized for 6 weeks of double-blind treatment with IBD98 0.8 g/day or IBD 1.2 g/day or placebo. The efficacy and safety of IBD98-M in mild to moderate active UC were primarily evaluated. At week 6, 1 (5.9%), 2 (12.5%), and 2 (11.1%) patients receiving IBD98-M 0.8 g, IBD98-M 1.2 g, and placebo, respectively, (p > 0.999) achieved clinical remission. Higher clinical response was seen in IBD98-M 1.2 g (31.3%) versus placebo (16.7%) and endoscopic improvement in IBD98-M 0.8 g (29.4%) versus placebo (22.2%) was seen. Fecal calprotectin levels were reduced in IBD98-M groups versus placebo (p > 0.05). IBD98-M patients achieved significant improvement in physical health summary score component of the SF-36 (p = 0.01 and p = 0.03 respectively) compared to placebo. IBD98-M did not meet the primary end point but had higher clinical response (1.2 g/day) and endoscopic improvement (0.8 g/day) compared to placebo. The safety result shown that IBD98-M treatment was safe and well tolerated in this patient population. No new safety signals or unexpected safety findings were observed during the study. Further trials with different stratification and longer follow-up may be needed to evaluate the efficacy.

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 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.

Objective. To explore fecal calprotectin levels in pediatric ulcerative colitis (UC) in relation with the validated clinical activity index PUCAI. Methods. This study included all 37 children (median age 14 years) with UC who had calprotectin measured (PhiCal ELISA Test) by the time of PUCAI assessment at the Children's Hospital of Helsinki in a total of 62 visits. Calprotectin values <100 μg/g of stool were considered as normal. The best cut-off value of each measure to predict 3-month clinical outcome was derived by maximizing sensitivity and specificity. Results. In clinically active disease (PUCAI ≥ 10), calprotectin was elevated in 29/32 patients (91% sensitivity). When in clinical remission, 26% (8/30) of the children had normal calprotectin but 7 (23%) had an exceedingly high level (>1000 μg/g). The best cut-off value for calprotectin for predicting poor outcome was 800 μg/g (sensitivity 73%, specificity 72%; area under the ROC curve being 0.71 (95%CI 0.57–0.85)) and for the PUCAI best cut-off values >10 (sensitivity 62%, specificity 64%; area under the ROC curve 0.714 (95%CI 0.58–0.85)). Conclusion. The clinical relevance of somewhat elevated calprotectin during clinical remission in pediatric UC is not known and, until further evidence accumulates, does not indicate therapy escalation.

Aim: This study aimed to evaluate the clinical significance of fecal calprotectin (FC) in assessment of ulcerative colitis (UC) patients' endoscopic patterns and clinical manifestation.Methods: A total of 143 UC patients who received colonoscopy and 108 controls were included. After providing stool samples, patients underwent total colonoscopy. FC was measured by an enzyme-linked immunosorbent assay (ELISA). Clinical activity was based on the Mayo score. Endoscopic findings was scored by the Ulcerative Colitis Endoscopic Index of Severity (UCEIS). Correlation analysis and receiver-operator characteristic (ROC) analysis were carried out to determine the significance of measurements.Results: The median (interquartile range, IQR) of FC levels was 211 (43–990) μg/g in UC and 87.5 (40.50~181) μg/g in the control group. Fecal calprotectin correlated significantly with both Mayo and UCEIS scores (Spearman's r 0.670 and 0.592, P &lt; 0.01). With a cut-off value of 164 μg/g for fecal calprotectin concentration, the area under the curve (AUC) in receiver operator characteristic analysis was 0.830, sensitivity was 85.42%, specificity was 73.68%, positive predictive value (PPV) was 62.12%, and negative predictive value (NPV) was 9.10% in predicting clinical active disease. Similarly, the power of FC to predict mucosal healing (MH) was modest. With a cut-off value of 154.5 μg/g, the AUC was 0.839, sensitivity was 72.34%, and specificity was 85.71%.Conclusion: For evaluating the disease activity of UC, FC is a clinically relevant biomarker for both clinically active disease and MH in patients with UC. But the cut-off value still needs large and multicenter studies for confirmation.

AbstractWhile immunomodulators (IMs) are used as key drugs in remission maintenance treatment for ulcerative colitis (UC), there has been no evidence to date for determining monitoring methods and drug withdrawal. Therefore, we examined if a decrease in white blood cell count (WBC) and an elevation in mean cell volume (MCV) could be used as optimization indices and if mucosal healing (MH) could be a rationale for determining the time of IM withdrawal. Subjects were 89 UC patients who were using IMs and for whom clinical remission had been maintained. Those with a Rachmilewitz Clinical Activity Index score of 4 or lower and those with a Mayo endoscopic subscore (MES) of 0 or 1 were defined as MH. The remission maintenance rates of the following comparative groups were examined: an IM continuation group and an IM withdrawal group; an IM continuation group with a WBC of less than 3000 or a MCV of 100 or greater and an IM continuation group with a WBC of 3000 or greater and a MCV of 99 or lower; an IM continuation group of patients for whom MH had been achieved and an IM continuation group of patients for whom MH had not been achieved; and an IM withdrawal group with a MES of 0 and an IM withdrawal group with a MES of 1. A significantly higher remission maintenance rate was observed in the IM continuation group compared to the withdrawal group (p < 0.01). No significant difference was observed between the IM continuation group with a WBC of less than 3000 or a MCV of 100 or greater and the IM continuation group with a WBC of 3000 or greater and a MCV of 99 or lower (p = 0.08). Higher remission maintenance rates were observed in the IM continuation group of patients for whom MH had been achieved compared to the IM continuation group of patients for whom MH had not been achieved (p = 0.03). No significant difference was observed between the IM withdrawal group with MES 0 and the IM withdrawal group with MES 1. (p = 0.48). This retrospective study showed that remission maintenance could be firmly obtained by continuing IM administration in case of endoscopic MH; however, MH was not an indicator of IM withdrawal.
