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 The endoscopic and histological healing are key therapeutic targets in ulcerative colitis(UC) patients. PICaSSO (Paddington International virtual ChromoendoScopy ScOre)1,2 is a new Virtual Chromoendoscopy Endoscopic (VCE) score to better define mucosal healing by mucosal and vascular features. Originally validated using iSCAN platform, the aim of this study was to evaluate the reproducibility of PICaSSO with NBI near focus platform and to assess if this could predict histological healing. Methods We prospectively studied 78 UC patients (mean age 43.4 years, 52.6% male) who underwent colonoscopy for colitis assessment or surveillance using NBI near focus (Olympus, Japan). Endoscopic activity was assessed by using ulcerative colitis Endoscopic Index of Severity (UCEIS) and PICaSSO; whilst histological activity was scored by the Robarts Histology Index (RHI). ROC curves were performed to evaluate sensitivity, specificity and accuracy of endoscopy scores to predict histological healing. Results Out of 78 patients, 47 (60.3%) were in clinical remission according to the partial Mayo score. 28(35.9%) and 32(41.0%) were in endoscopic remission according to UCEIS≤1 and PICaSSO≤3, respectively. The best cut-off of UCEIS to predict histological healing was less or equal to 1. Sensitivity, specificity and accuracy were 84.6% (95% CI 63.5, 96.4), 88.5% (95% CI 70.1, 97.8) and 87.2% (95% CI 75.6, 93.6), respectively. The Area Under the ROC curve (AUROC) was 93.3% (95% CI 88.2, 98.3). The best threshold of PICaSSO in the prediction of histological healing was less or equal to 3. PICaSSO ≤ 3 have sensitivity of 96.2% (95% CI 76.9, 100), specificity of 86.5% (95% CI 67.3, 96.2) and accuracy of 89.7% (95% CI 77.6, 96.2) to predict histological healing, estimated as RHI ≤ 3. The AUROC was 95.3% (95% CI 91.1, 99.5). Conclusion PICaSSO VCE score can be easily and accurately reproduced with NBI near focus platform and it has better operating characteristics than UCEIS to predict histological healing defined by RHI.

Abstract Background Endoscopic mucosal healing is considered as an important therapeutic goal in ulcerative colitis (UC) patients, and several endoscopic evaluations for colonic mucosa such as Mayo endoscopic subscore (MES) and Colitis Endoscopic Index of Severity (UCEIS) are used in clinical practice. Though the strict mucosal healing is defined as MES 0, the relapse of UC has been shown in the patients diagnosed as MES 0. In the present study, we aimed to investigate the efficacy of Linked Color Imaging (LCI), a novel endoscopic enhancement system, to predict long-term prognosis in UC patients diagnosed with MES 0. Methods Twenty-six patients with UC in clinical remission and diagnosed with MES 0 were enrolled. Endoscopic colonic images were assessed by LCI and UCEIS, using a LASEREO endoscopic system (FUJIFILM Co., Tokyo, Japan). Endoscopic LCI images were classified into three subgroups by LCI classification as previously reported. Briefly, LCI patterns were classified as A, no redness; B, redness with visible vessels; and C, redness without visible vessels. Forty months was defined as the time interval between endoscopic diagnosis and relapse of UC. Histological activity was scored according to the Geboes’ score (GS) and the active mucosa was defined by GS>2B.1. Results LCI classification can further subdivide the colonic mucosa diagnosed as MES 0. The patients with LCI-A showed no relapse and the non-relapse rates compared with the patients with LCI-B showed significantly higher (p = 0.033), while the relapse rates of the patients with UCEIS 0 showed no difference compared with UCEIS 1 (p = 0.148). There was no statistical difference in the composition of LCI-A and relapse rate between active and inactive mucosa diagnosed by GS score. Conclusion Endoscopic LCI classification can further subdivide samples diagnosed MES 0. LCI can be a novel and surpassing approach to evaluate mucosal healing and predict the outcome in UC patients.

Abstract Background The role of IL-12/23 in the pathogenesis of ulcerative colitis (UC) is unclear. We analyzed mucosal IL-12/23 expression and its relationship with endoscopic severity, histological activity, and UC relapse. Methods Rectal biopsies were collected from 70 UC patients with clinical remission. IL-12, IL-23, IFN-γ, IL-17A, and IL-17F mRNA expression was measured by real-time PCR. Endoscopic severity and histological activity were evaluated using the Mayo endoscopic subscore (MES) and the Geboes score, respectively. Results The longest follow-up period was 51 months. Thirty-four patients relapsed during the study period. Samples from these subsequently relapsed patients formed the “relapse” group, while those from patients that did not relapse formed the “remission” group. IL-12 (P = 0.0003) and IL-23 (P = 0.014) mRNA expression was significantly higher in the relapse than the remission group. Expression of IL-23 (P = 0.015) but not IL-12 (P = 0.374) was correlated with MES. However, in patients with an MES of 0 and 1, IL-12 expression was statistically higher in the relapse than the remission group (P = 0.0015, P = 0.0342). IL-12 and IL-23 expression did not vary significantly between histologically active and inactive mucosa; both were higher in histologically inactive patients in the remission group (IL-12: P = 0.0002, IL-23: P = 0.046). Conclusions Rectal IL-12 and IL-23 expression was elevated in the relapse group, but IL-12 was more strongly associated with UC relapse, irrespective of endoscopic severity and histological activity. Mucosal IL-12 was elevated in patients with deep mucosal healing. Our results suggest an important role of IL-12 in UC pathogenesis and the molecular mechanism of UC relapse.

Abstract Background and study aims Mucosal healing is a current treatment target in ulcerative colitis (UC), while histological remission is another target. The aim of this study was to evaluate the efficiency of magnified narrow band imaging (NBI) findings of mucosal healing and their relationship with histological activity and prognosis. Patients and methods Patients with UC who underwent total colonoscopy between January 2010 and December 2012 with left-sided or total-colitis type UC and achieved clinical remission with an endoscopic Mayo score of 0 or 1 were included. Each colon section was observed with white light and magnified NBI, with the colonoscopy being repeated at 1-year follow-up. We assessed the relationships of magnified NBI with histological disease activity and prognosis. Magnified NBI findings were divided into three categories; honeycomb-like blood vessels (BV-H), blood vessels shaped like bare branches (BV-BB), and blood vessels shaped like vines (BV-V). Results Fifty-two patients were included. The percentage of remitted mucosa with BV-BB was 37 %, while that of mucosa with scars with BV-H was 35 %. BV-H and BV-BB did not show pathological activity (12/292 and 8/299, respectively), while BV-V showed high pathological activity (27/33, 81 %). There was a correlation between magnified NBI findings and pathological findings (P < 0.01). The odds ratio for inflammation activity at 1-year follow-up was 14.2 for BV-BB (95 % CI, 3.3 – 60.9) Conclusion Magnified NBI findings showed a good relationship with histological activity. This suggests that we could estimate histological activity without biopsy, and also the possibility of predicting relapse over the following year.

The treatment of ulcerative colitis (UC) has changed over the last decade. It is extremely important to optimize the therapies which are available nowadays and commonly used in daily clinical practice, as well as to stimulate the search for more powerful drugs for the induction and maintenance of sustained and durable remission, thus preventing further complications. Therefore, it is mandatory to identify the patients' prognostic variables associated with an aggressive clinical course and to test the most potent therapies accordingly.To date, the conventional therapeutic approach based on corticosteroids, salicylates (sulfasalazine, 5-aminosalicylic acid) or immunosuppressive agents is commonly used as a first step to induce and to maintain remission. However, in recent years, knowledge of new pathogenetic mechanisms of ulcerative colitis have allowed us to find new therapeutic targets leading to the development of new treatments that directly target proinflammatory mediators, such as TNF-alpha, cytokines, membrane migration agents, cellular therapies.The aim of this review is to provide the most significant data regarding the therapeutic role of drugs in UC and to give an overview of biological and experimental drugs that will become available in the near future. In particular, we will analyse the role of these drugs in the treatment of acute flare and maintenance of UC, as well as its importance in mucosal healing and in treating patients at a high risk of relapse.
