Abstract
Although the increased risk of colorectal neoplasia in patients with both primary sclerosing cholangitis (PSC) and ulcerative colitis (UC; termed PSC-UC) is well documented, the mechanism through which concomitant PSC increases the risk of colorectal neoplasia remains unclear. Given that the risk of colorectal neoplasia in UC is positively correlated with increased histologic inflammation, this study sought to investigate whether increased histologic inflammation could be used to stratify the risk of dysplasia development in patients with PSC-UC. Twenty patients with PSC-UC and dysplasia were compared with 30 control patients with PSC-UC who had no history of neoplasia. For each patient, all surveillance biopsies were scored using a 4-point scoring system: (1) no epithelial neutrophils = 0, (2) cryptitis only = 1, (3) cryptitis plus crypt abscess in <50% of crypts = 2, and (4) crypt abscess in ≥50% of crypts, erosion, neutrophilic exudate, and/or ulceration = 3. A score was designated for each biopsy, and both mean and maximum inflammation scores were calculated from all biopsies taken during each colonoscopy. The inflammation burden score was calculated for each surveillance interval by multiplying the average maximum score between each pair of surveillance episodes by the length of the surveillance interval in years. The average scores derived from all colonoscopies for each patient were used to determine the patient's overall mean, maximum, and inflammation burden scores. In both the dysplasia and control groups, the 3 summative inflammation scores were calculated independently for the entire colon, right colon, and left colon. The dysplasia group consisted of 14 (70%) men and 6 (30%) women, with a mean age of 27 years at UC diagnosis and a long history of pancolitis (mean duration: 17 y). A total of 49 dysplastic lesions were detected in the dysplasia group, and 8 (40%) of the 20 patients had multifocal dysplasia. The majority of dysplastic lesions belonged to nonconventional subtypes (n = 28; 57%) and were located in the right colon (n = 37; 76%). Irrespective of the colon segment, there was no significant difference in the 3 summative inflammation scores between the dysplasia and control groups (P > 0.05). However, in each group, the 3 summative inflammation scores were significantly higher in the right colon than in the left colon (P< 0.05). In conclusion, patients with PSC-UC exhibit increased histologic inflammation in the right colon compared with the left colon, regardless of the presence of dysplasia. Although this may provide an explanation for the predominance of right-sided colorectal neoplasia in patients with PSC-UC, increased histologic inflammation does not reliably predict an elevated risk of dysplasia in patients with PSC-UC. These findings reinforce the current recommendation for annual endoscopic surveillance for all patients with PSC-UC, irrespective of the extent and severity of inflammation.

Abstract
The term nonconventional dysplasia has been coined to describe several underrecognized morphologic patterns of epithelial dysplasia in inflammatory bowel disease (IBD), but to date, the full recognition of these newly characterized lesions by pathologists is uneven. The identification of nonconventional dysplastic subtypes is becoming increasingly important, as they often present as invisible/flat dysplasia and are more frequently associated with advanced neoplasia than conventional dysplasia on follow-up. This review describes the morphologic, clinicopathologic, and molecular characteristics of seven nonconventional subtypes known to date, as well as their potential significance in the clinical management of IBD patients.

Abstract
Interleukin-37 (IL-37) is a newly discovered member of IL-1 family. The cytokine was proved to have extensive protective effects in infectious diseases, allergic diseases, metabolic diseases, autoimmune diseases and tumors since its discovery. IL-37 was mainly produced by immune and some non-immune cells in response to inflammatory stimulus. The IL-37 precursors can convert into the mature forms after caspase-1 cleavage and activation intracellularly, and then bind to Smad-3 and transfer to the nucleus to inhibit the production and functions of proinflammatory cytokines; extracellularly, IL-37 binds to cell surface receptors to form IL-37/IL-18Rα/IL-1R8 complex to exert immunosuppressive function via inhibiting/activating multiple signal pathways. In addition, IL-37 can attenuate the pro-inflammatory effect of IL-18 through directly or forming an IL-37/IL-18BP/IL-18Rβ complex. Therefore, IL-37 has the ability to suppress innate and acquired immunity of the host, and effectively control inflammatory stimulation, which was considered as a new hallmark of cancer. Specifically, it is concluded that IL-37 can inhibit the growth and migration of tumor cells, prohibit angiogenesis and mediate the immunoregulation in tumor microenvironment, so as to exert effective anti-tumor effects. Importantly, latest studies also showed that IL-37 may be a novel therapeutic target for cancer monitoring. In this review, we summarize the immunoregulation roles and mechanisms of IL-37 in anti-tumor process, and discuss its progress so far and potential as tumor immunotherapy.

Abstract
BACKGROUND/AIMS Primary sclerosing cholangitis (PSC) represents the most common hepatobiliary extraintestinal manifestation of inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn's disease (CD). Limited data exist on PSC in patients with IBD from India. We aimed to assess the prevalence and disease spectrum of PSC in Indian patients with IBD. METHODS Database of IBD patients at 5 tertiary care IBD centers in India were analyzed retrospectively. Data were extracted and the prevalence of PSC-IBD was calculated. RESULTS Forty-eight patients out of 12,216 patients with IBD (9,231 UC, 2,939 CD, and 46 IBD unclassified) were identified to have PSC, resulting in a prevalence of 0.39%. The UC to CD ratio was 7:1. Male sex and pancolitis (UC) or colonic CD were more commonly associated with PSC-IBD. The diagnosis of IBD preceded the diagnosis of PSC in most of the patients. Majority of the patients were symptomatic for liver disease at diagnosis. Eight patients (16.66%) developed cirrhosis, 5 patients (10.41%), all UC, developed malignancies (3 colorectal cancer [6.25%] and 2 cholangiocarcinoma [4.16%]), and 3 patients died (2 decompensated liver disease [4.16%] and 1 cholangiocarcinoma [2.08%]) on follow-up. None of the patients mandated surgical therapy for IBD. CONCLUSIONS Concomitant PSC in patients with IBD is uncommon in India and is associated with lower rates of development of malignancies.

Abstract
Primary sclerosing cholangitis (PSC) is the classical hepatobiliary manifestation of inflammatory bowel disease (IBD) and a lead indication for liver transplantation (LT) in the western world. In this article, we present a Consensus Statement on LT practice, developed by a dedicated Guidelines' Taskforce of the European Society of Organ Transplantation (ESOT). The overarching goal is to provide practical guidance on commonly debated topics, including indications and timing of LT, management of bile duct stenosis in patients on the transplant waiting list, technical aspects of transplantation, immunosuppressive strategies post-transplant, timing and extension of intestinal resection and futility criteria for re-transplantation.

Abstract
Primary sclerosing cholangitis (PSC) is characterized by progressive biliary inflammation and fibrosis. Although gut commensals are associated with PSC, their causative roles and therapeutic strategies remain elusive. Here we detect abundant Klebsiella pneumoniae (Kp) and Enterococcus gallinarum in fecal samples from 45 PSC patients, regardless of intestinal complications. Carriers of both pathogens exhibit high disease activity and poor clinical outcomes. Colonization of PSC-derived Kp in specific pathogen-free (SPF) hepatobiliary injury-prone mice enhances hepatic Th17 cell responses and exacerbates liver injury through bacterial translocation to mesenteric lymph nodes. We developed a lytic phage cocktail that targets PSC-derived Kp with a sustained suppressive effect in vitro. Oral administration of the phage cocktail lowers Kp levels in Kp-colonized germ-free mice and SPF mice, without off-target dysbiosis. Furthermore, we demonstrate that oral and intravenous phage administration successfully suppresses Kp levels and attenuates liver inflammation and disease severity in hepatobiliary injury-prone SPF mice. These results collectively suggest that using a lytic phage cocktail shows promise for targeting Kp in PSC.

Abstract
Primary sclerosing cholangitis (PSC) is an immune-mediated disease of the bile ducts that co-occurs with inflammatory bowel disease (IBD) in almost 90% of cases. Colorectal cancer is a major complication of patients with PSC and IBD, and these patients are at a much greater risk compared to patients with IBD without concomitant PSC. Combining flow cytometry, bulk and single-cell transcriptomics, and T and B cell receptor repertoire analysis of right colon tissue from 65 patients with PSC, 108 patients with IBD and 48 healthy individuals we identified a unique adaptive inflammatory transcriptional signature associated with greater risk and shorter time to dysplasia in patients with PSC. This inflammatory signature is characterized by antigen-driven interleukin-17A (IL-17A)+ forkhead box P3 (FOXP3)+ CD4 T cells that express a pathogenic IL-17 signature, as well as an expansion of IgG-secreting plasma cells. These results suggest that the mechanisms that drive the emergence of dysplasia in PSC and IBD are distinct and provide molecular insights that could guide prevention of colorectal cancer in individuals with PSC.

Possible role of nutrition in the prevention of inflammatory bowel disease-related colorectal cancer: A focus on human studies. Nutrition 2023; 110:111980. [PMID: 36965240 DOI: 10.1016/j.nut.2023.111980] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 01/10/2023] [Accepted: 01/22/2023] [Indexed: 02/05/2023]
Abstract
Patients with inflammatory bowel disease (IBD) are at substantially high risk for colorectal cancer (CRC). IBD-associated CRC accounts for roughly 10% to 15% of the annual mortality in patients with IBD. IBD-related CRC also affects younger patients compared with sporadic CRC, with a 5-y survival rate of 50%. Regardless of medical therapies, the persistent inflammatory state characterizing IBD raises the risk for precancerous changes and CRC, with additional input from several elements, including genetic and environmental risk factors, IBD-associated comorbidities, intestinal barrier dysfunction, and gut microbiota modifications. It is well known that nutritional habits and dietary bioactive compounds can influence IBD-associated inflammation, microbiome abundance and composition, oxidative stress balance, and gut permeability. Additionally, in recent years, results from broad epidemiologic and experimental studies have associated certain foods or nutritional patterns with the risk for colorectal neoplasia. The present study aimed to review the possible role of nutrition in preventing IBD-related CRC, focusing specifically on human studies. It emerges that nutritional interventions based on healthy, nutrient-dense dietary patterns characterized by a high intake of fiber, vegetables, fruit, ω-3 polyunsaturated fatty acids, and a low amount of animal proteins, processed foods, and alcohol, combined with probiotic supplementation have the potential of reducing IBD-activity and preventing the risk of IBD-related CRC through different mechanisms, suggesting that targeted nutritional interventions may represent a novel promising approach for the prevention and management of IBD-associated CRC.

J Crohns Colitis 2022; 16:1825-1834. [PMID: 35771958 DOI: 10.1093/ecco-jcc/jjac090] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/12/2022]
Abstract
BACKGROUND AND AIMS Patients with primary sclerosing cholangitis and inflammatory bowel disease [termed PSC-IBD] have a higher risk of developing colorectal neoplasia than those with IBD alone. The mechanism by which concomitant PSC increases the risk of colorectal neoplasia remains unknown. Seven distinct non-conventional dysplastic subtypes have been recently described in IBD, including crypt cell dysplasia, hypermucinous dysplasia, goblet cell-deficient dysplasia, dysplasia with increased Paneth cell differentiation [DPD], sessile serrated lesion [SSL]-like dysplasia, traditional serrated adenoma [TSA]-like dysplasia, and serrated dysplasia, not otherwise specified [NOS]. Despite the lack of high-grade morphological features, crypt cell, hypermucinous, and goblet cell-deficient dysplasias often show molecular features characteristic of advanced neoplasia [i.e. aneuploidy and KRAS mutations] and are more frequently associated with advanced neoplasia than conventional dysplasia on follow-up. We aimed to characterise clinicopathological features of dysplasia found in PSC-IBD patients. METHODS A cohort of 173 PSC-IBD patients were analysed. All dysplastic lesions were subtyped as either conventional or non-conventional dysplasia. The clinicopathological features of PSC-IBD patients with neoplasia were also compared with those of non-PSC IBD patients with neoplasia. RESULTS There were 109 [63%] men and 64 [37%] women, with a mean age of 26 years at IBD diagnosis and a long history of IBD [mean duration: 14 years]. Ulcerative colitis was the most common IBD subtype [80%], and the majority of patients [92%] had a history of pancolitis. A total of 153 dysplastic lesions were detected in 54 [31%] patients, 35 [65%] of whom had multifocal dysplasia. One additional patient presented with colorectal cancer [CRC] without a history of dysplasia. Dysplasia was often non-conventional [n = 93; 61%], endoscopically/grossly invisible [n = 101; 66%], and right/proximal-sided [n = 90; 59%]. All seven non-conventional subtypes were identified, including 46 [30%] crypt cell dysplasia, 23 [15%] hypermucinous dysplasia, 12 [8%] goblet cell-deficient dysplasia, seven [5%] DPD, three [2%] TSA-like dysplasia, one [1%] SSL-like dysplasia, and one [1%] serrated dysplasia NOS. Follow-up information was available for 86 lesions, of which 32 [37%] were associated with subsequent detection of advanced neoplasia [high-grade dysplasia or CRC] within a mean follow-up time of 55 months. PSC-IBD patients with neoplasia were more likely to have pancolitis [98%, p = 0.039] and a longer IBD duration [mean: 17 years, p = 0.021] than those without neoplasia [89% and 12 years, respectively]. When compared with a cohort of non-PSC IBD patients with neoplasia, the PSC-IBD group with neoplasia was more often associated with non-conventional [61%, p <0.001], invisible [66%, p <0.001], and right/proximal-sided [59%, p = 0.045] dysplasias [vs 25%, 21%, and 47%, respectively, for the non-PSC IBD group]. The rate of advanced neoplasia was nearly 2-fold higher in the PSC-IBD group [37%] compared with the non-PSC IBD group [22%] [p = 0.035]. CONCLUSIONS Nearly a third of PSC-IBD patients developed dysplasia, which is often associated with non-conventional dysplastic features, invisible endoscopic/gross appearance, right/proximal-sided colon, multifocality, and advanced neoplasia on follow-up. These findings underscore the importance of recognising these non-conventional subtypes by practising pathologists and the need for careful and frequent endoscopic surveillance, with random biopsies, in PSC-IBD patients.

Abstract
The association between inflammatory bowel disease and colorectal cancer is well known. Although the overall incidence of inflammatory bowel disease has declined recently, patients with this disease still have a 1.7-fold increased risk of colorectal cancer. The risk factors for developing colorectal cancer include extensive colitis, young age at diagnosis, disease duration, primary sclerosing cholangitis, chronic colonic mucosal inflammation, dysplasia lesion, and post-inflammatory polyps. In patients with inflammatory bowel disease, control of chronic inflammation and surveillance colonoscopies are important for the prevention of colorectal cancer. The 2017 guidelines from the European Crohn's and Colitis Organisation suggest that colonoscopies to screen for colorectal cancer should be performed when inflammatory bowel disease symptoms have lasted for 8 years. Current evidence supports the use of chemoprevention therapy with mesalamine to reduce the risk of colorectal cancer in patients with ulcerative colitis. Other compounds, including thiopurine, folic acid, statin, and tumor necrosis factor-α inhibitor, are controversial. Large surveillance cohort studies with longer follow-up duration are needed to evaluate the impact of drugs on colorectal cancer risks.

Modulation of Mismatch Repair and the SOCS1/p53 Axis by microRNA-155 in the Colon of Patients with Primary Sclerosing Cholangitis. Int J Mol Sci 2022; 23:ijms23094905. [PMID: 35563301 PMCID: PMC9100906 DOI: 10.3390/ijms23094905] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2022] [Revised: 04/24/2022] [Accepted: 04/26/2022] [Indexed: 12/10/2022] Open
Abstract
Deficient mismatch repair (MMR) proteins may lead to DNA damage and microsatellite instability. Primary sclerosing cholangitis (PSC) is a risk factor for colitis-associated colon cancer. MiR-155 is suggested to act as a key regulating node, linking inflammation and tumorigenesis. However, its involvement in the chronic colitis of PSC-UC patients has not been examined. We investigated the involvement of miR-155 in the dysregulation of MMR genes and colitis in PSC patients. Colon tissue biopsies were obtained from patients with PSC, PSC with concomitant ulcerative colitis (PSC-UC), uncomplicated UC, and healthy controls (n = 10 per group). In the ascending colon of PSC and PSC-UC patients, upregulated miR-155 promoted high microsatellite instability and induced signal transducer and activator of transcription 3 (STAT-3) expression via the inhibition of suppressors of cytokine signalling 1 (SOCS1). In contrast, the absence of miR-155 overexpression in the sigmoid colon of PSC-UC patients activated the Il-6/S1PR1 signalling pathway and imbalanced the IL17/FOXP3 ratio, which reinforces chronic colitis. Functional studies on human intestinal epithelial cells (HT-29 and NCM460D) confirmed the role of miR-155 over-expression in the inhibition of MMR genes and the modulation of p53. Moreover, those cells produced more TNFα upon a lipopolysaccharide challenge, which led to the suppression of miR-155. Additionally, exposure to bile acids induced upregulation of miR-155 in Caco-2 cell lines. Thus, under different conditions, miR-155 is involved in either neoplastic transformation in the ascending colon or chronic colitis in the sigmoid colon of patients with PSC. New insight into local modulation of microRNAs, that may alter the course of the disease, could be used for further research on potential therapeutic applications.

Abstract
BACKGROUND AND AIMS Patients with inflammatory bowel diseases (IBDs) are at risk of developing a variety of other immune-mediated inflammatory diseases (IMIDs). The influence of co-occurring IMIDs on the disease course of IBD remains unknown. The aim of this study was therefore to conduct a systematic review and meta-analysis of the impact of IMIDs on phenotypic presentation and outcome in patients with IBD. METHODS PubMed and Embase were searched from their earliest records through December 2018 and updated in October 2019 for studies reporting proportions or ratios of IBD-related disease outcomes in patients with and without co-occurring IMIDs. Meta-analyses were performed to estimate summary proportions and risks of the main outcomes. PRISMA guidelines were used, and study quality was assessed according to the Newcastle-Ottawa Scale. RESULTS A total of 93 studies were identified, comprising 16,064 IBD patients with co-occurring IMIDs and 3,451,414 IBD patients without IMIDs. Patients with IBD and co-occurring IMIDs were at increased risk of having extensive colitis or pancolitis (risk ratio, 1.38; 95% Cl, 1.25-1.52; P < 0.01, I2 = 86%) and receiving IBD-related surgeries (risk ratio, 1.17; 95% Cl, 1.01-1.36; P = 0.03; I2 = 85%) compared with patients without IMIDs. Co-occurrence of IMIDs other than primary sclerosing cholangitis in patients with IBD was associated with an increased risk of receiving immunomodulators (risk ratio, 1.15; 95% Cl, 1.06-1.24; P < 0.01; I2 = 60%) and biologic therapies (risk ratio, 1.19; 95% Cl, 1.08-1.32; P < 0.01; I2 = 53%). CONCLUSION This meta-analysis found that the presence of co-occurring IMIDs influences the disease course of IBD, including an increased risk of surgery and its phenotypical expression.

Abstract
Primary sclerosing cholangitis (PSC) is commonly accompanied by ulcerative colitis (UC). MicroRNA-506 modulates expression of genes which are essential for sphingosine-mediated signaling pathway and intestinal mucosa protection. We investigated whether miR-506 and its target genes are involved in phenotypic presentations of colonic inflammation and/or neoplasia. We analyzed serum and colon tissue samples collected from patients with PSC, PSC with concurrent UC (PSC + UC), UC alone, and healthy controls (n = 10 each). MiR-506 was substantially upregulated in ascending colons of PSC and PSC + UC patients, in contrast to sigmoid colons of PSC and UC patients. Upregulation of miR-506 was associated with inhibition of SPHK1, AE2, InsP3R3, and p53. Colonic suppression of miR-506 presented in UC was accompanied by substantially increased DNMT1, SPHK1, and S1P lyase expressions. A functional in vitro analysis in Caco-2 cells showed that the induction of miR-506 activity by miR-506 mimic or GDCDA bile acid suppressed, whereas inhibition of miR-506 by miR-506 inhibitor or lipopolysaccharide (LPS) upregulated the expression of the examined target genes. A different phenotypic presentation of colitis may be related to miR-506 expression. In ascending colons with PSC + UC, upregulation of miR-506 may result in failure of bicarbonate secretion and inhibition of p53, which predisposes to pro-tumorigenic transformation. In contrast, downregulation of miR-506 enhances S1P production, leading to pro-inflammatory signaling.

Abstract
INTRODUCTION: Primary sclerosing cholangitis (PSC) is a cholestatic liver disorder that is frequently associated with ulcerative colitis (UC). Patients with PSC and UC (PSC-UC) have a higher risk of colorectal neoplasia compared with patients with UC. The oncogenic properties of microRNA-346 (miR-346) have been recently reported. We investigated the expression of miR-346 and its 2 target genes, the receptor of vitamin D (VDR), and the tumor necrosis factor-α (TNF-α), which are known to modulate carcinogenesis. METHODS: Ascending and sigmoid colon biopsies were obtained from patients with PSC, PSC and UC (PSC-UC), UC, and healthy controls (n = 10 in each group). Expressions of VDR, TNF-α, 18S RNA, p27Kip1, miR-346, and reference microRNA, miR-191, were evaluated by real-time PCR using human TaqMan Gene Expression and TaqMan MicroRNA Assays. Functional studies with miR-346 mimic and inhibitor were conducted in HepG2 and Caco-2 cells. The effect of ursodeoxycholic acid on miR-346 expression was examined in Caco-2 cells. RESULTS: An increased expression of miR-346 in the ascending colon of PSC-UC was observed (P < 0.001 vs all groups). In patients with UC, an exceptionally low colonic expression of miRNA-346 was accompanied by the extensive upregulation of VDR and TNF-α genes. A functional in vitro analysis demonstrated that inhibition of miR-346 resulted in the upregulation of VDR and TNF-α, whereas the induction of miR-346 activity suppressed VDR, TNF-α, and p27Kip1. DISCUSSION: The upregulation of miRNA-346 in the colon of patients with PSC may be responsible for the disturbance of VDR and TNF-α signaling pathway, which could result in an inadequate suppression of neoplasia.

The role of oral vancomycin in inducing remission for biologic-experienced ulcerative colitis with concomitant primary sclerosing cholangitis and liver transplantation.

Abstract
While a minority of patients with ulcerative colitis has primary sclerosing cholangitis (PSC), a significant proportion of patients with PSC have ulcerative colitis. The activity of PSC is usually not commensurate with the degree of concomitant colonic inflammation. Moreover, up to one-third of patients with a history of ulcerative colitis may paradoxically experience worsening of their colonic inflammation despite receiving immunosuppression after liver transplantation for PSC. There is a dearth of data pertaining to the management of ulcerative colitis in this post-transplantation patient population. We hereby delineate the case of a patient with severe refractory ulcerative colitis in the aftermath of liver transplantation due to PSC who eventually responded to oral vancomycin after failure of biologic therapy. Since current data implicate that patients with ulcerative colitis and PSC often present with distinct alterations of their colonic microbiome, oral vancomycin may be conjectured to demonstrate a therapeutic role. In this article, the review of literature suggests that oral vancomycin might indeed be an effective substitute in patients in whom the uptake of biologic agents may be challenging owing to their already immunosuppressed status.

Abstract
BACKGROUND Diagnosing low grade intraepithelial neoplasia (LGIN) in patients with ulcerative colitis (UC) is difficult. Distinguishing between sporadic adenoma (SA) and UC associated LGIN is even more challenging but has clinical impact. We aimed to examine, if the morphological distinction between both entities is reliably possible, how it influences patient's outcome and the role of the endoscopist in this decision with respect to current endoscopy classification schemes. METHODS Seven pathologists retrospectively reevaluated 425 cases of LGIN in UC patients, diagnosed between 2009 and 2017 with preceding expert consensus and follow up in two separate readings, based on published morphological differentiation criteria. In the first evaluation, the observers were blinded to any clinical data. In the second evaluation, they knew patients' age as well as endoscopic features. They also rated their subjective diagnostic certainty. RESULTS Diagnostic correctness improved significantly in the second assessment as did the pathologists' confidence in their diagnoses (p < 0.001 - p = 0.019). Knowledge of clinical and endoscopical data led to a higher percentage of SA (71.8% vs. 85.6%). UC associated LGIN showed significant earlier LGIN relapse as well as more high grade intraepithelial neoplasia and carcinoma during follow up (p < 0.001, p < 0.001, p = 0.005). CONCLUSIONS Distinction between SA and UC associated LGIN is important as it has an impact on patients' follow up and treatment. Morphological distinction remains difficult with moderate interobserver variability. Adequate clinical information significantly improves pathologists' diagnoses as well as their confidence in their diagnoses.

Abstract
BACKGROUND AND AIMS Extraintestinal manifestations are common in inflammatory bowel disease patients, although there are few data available on their diagnosis, management and follow-up. We systematically reviewed the literature evidence to evaluate tools and investigations used for the diagnosis and for the assessment of the treatment response in inflammatory bowel disease patients with extraintestinal manifestations. METHODS We searched in PubMed, Embase and Web of Science from January 1999-December 2019 for all interventional and non-interventional studies published in English assessing diagnostic tools and investigations used in inflammatory bowel disease patients with extraintestinal manifestations. RESULTS Forty-five studies (16 interventional and 29 non-interventional) were included in our systematic review, enrolling 7994 inflammatory bowel disease patients. The diagnostic assessment of extraintestinal manifestations was performed by dedicated specialists in a percentage of cases ranging from 60-100% depending on the specific condition. The clinical examination was the most frequent diagnostic strategy, accounting for 35 studies (77.8%). In patients with primary sclerosing cholangitis or rheumatological symptoms, biochemical and imaging tests were also performed. Anti-TNF agents were the most used biological drugs for the treatment of extraintestinal manifestations (20 studies, 44.4%), and the treatment response varied from 59.1% in axial spondyloarthritis to 88.9% in ocular manifestations. No benefit was detected in primary sclerosing cholangitis patients after treatment with biologics. CONCLUSIONS In the clinical management of inflammatory bowel disease patients with extraintestinal manifestations the collaboration of dedicated specialists for diagnostic investigations and follow-up is key to ensure the best of care approach. However, international guidelines are needed to homogenise and standardise the assessment of extraintestinal manifestations.

Abstract
BACKGROUND Primary sclerosing cholangitis is a classical extraintestinal manifestation in patients with ulcerative colitis. However, the impact of primary sclerosing cholangitis on the disease course is incompletely understood. OBJECTIVE This study aimed to assess the impact of primary sclerosing cholangitis on disease phenotype and its course in patients with ulcerative colitis. DESIGN This is a retrospective study with 3:1 matched cohorts. SETTINGS Tertiary care center's electronic database was used for data analysis from 2000 and 2018. PATIENTS Of 782 patients with ulcerative colitis, 77 patients who had coincident primary sclerosing cholangitis were included. MAIN OUTCOME MEASURES The primary outcomes evaluated were disease characteristics including colonic disease activity, temporal change of disease course, colorectal neoplasia, and colectomy rates. RESULTS Disease activity during acute flares, assessed by the complete Mayo score, was significantly lower in patients with primary sclerosing cholangitis (6.2 vs 7.3; p < 0.001). In addition, disease activity in patients with primary sclerosing cholangitis was decreased, especially within the first 10 years after disease onset, and biological therapy with anti-tumor necrosis factor and anti-integrin agents was commenced less frequently (22% vs 35%; p = 0.043) and later (10-year risk: 17.4% vs 27.8%; p = 0.034). Patients with primary sclerosing cholangitis were younger at colitis diagnosis (23.3 vs 29.3 years; p < 0.001) and had more extensive disease (75% vs 46%; p < 0.001). Colorectal cancer was more frequently detected in patients with coincident primary sclerosing cholangitis (6/77 vs 16/705; p = 0.016). Colectomy rates did not differ between both groups (14.3% vs 14.5%; p = 0.56). In contrast, patients with ulcerative colitis had to undergo surgery more frequently because of therapy-refractant inflammation, whereas surgery due to neoplasia development was increased in patients with coincident primary sclerosing cholangitis (p = 0.013). LIMITATIONS The study was limited by its retrospective design. CONCLUSION Patients who have ulcerative colitis with coincident primary sclerosing cholangitis develop a distinct disease course characterized by an earlier disease onset and lower disease activity, but more frequent extensive disease manifestation and higher risk for colorectal cancer.

FENOTIPO DE ENFERMEDAD DISTINTIVO DE LA COLITIS ULCERATIVA EN PACIENTES CON COLANGITIS ESCLEROSANTE PRIMARIA CONCOMITANTE: EVIDENCIA DE UN ESTUDIO RETROSPECTIVO GRANDE CON COHORTES EMPAREJADAS: La colangitis esclerosante primaria es una manifestación extraintestinal clásica en pacientes con colitis ulcerativa. Sin embargo, el impacto de la colangitis esclerosante primaria en el curso de la enfermedad no es comprendido completamente.Evaluar el impacto de la colangitis esclerosante primaria en el fenotipo y curso de la enfermedad en pacientes con colitis ulcerativa.Este es un estudio retrospectivo con cohortes emparejadas 3:1.La base de datos electrónica de un centro de atención terciaria se utilizó para el análisis de datos de 2000 a 2018.782 pacientes con colitis ulcerativa, 77 padecían colangitis esclerosante primaria concomitante y fueron incluidos.Se evaluaron las características de la enfermedad, incluida la actividad de enfermedad colónica, el cambio temporal del curso de la enfermedad, la neoplasia colorrectal y las tasas de colectomía.La actividad de la enfermedad durante los brotes agudos, evaluada por la puntuación completa de Mayo, fue significativamente menor en pacientes con colangitis esclerosante primaria (6.2 vs 7.3; p < 0.001). Además, la actividad de la enfermedad en pacientes con colangitis esclerosante primaria se redujo especialmente en los primeros 10 años después del inicio de la enfermedad, y la terapia biológica con agentes anti-TNF y anti-integrina se inició con menos frecuencia (22% vs 35%; p = 0.043) y más tarde (riesgo a 10 años: 17.4% vs 27.8%; p = 0.034). Los pacientes con colangitis esclerosante primaria eran más jóvenes en el momento del diagnóstico de colitis (23.3 vs 29.3 años; p < 0.001) y tenían enfermedad más extensa (75% vs 46%; p < 0.001). El cáncer colorrectal se detectó con mayor frecuencia en pacientes con colangitis esclerosante primaria concomitante (6/77 vs 16/705; p = 0.016). Las tasas de colectomía no fueron diferentes entre ambos grupos (14.3% vs 14.5%; p = 0.56). En contraste, los pacientes con colitis ulcerativa tuvieron que someterse a cirugía con mayor frecuencia debido a inflamación refractaria a la terapia, mientras que el desarrollo de neoplasia se incrementó en pacientes con colangitis esclerosante primaria concomitante (p = 0.013).El estudio estuvo limitado por su diseño retrospectivo.Los pacientes con colitis ulcerativa con colangitis esclerosante primaria concomitante desarrollan un curso de enfermedad distintivo caracterizado por un inicio temprano de la enfermedad y una menor actividad de la enfermedad, pero con manifestación de enfermedad extensa más frecuente y un mayor riesgo de cáncer colorrectal.

Abstract
Inflammatory bowel disease increases the risk of developing colon cancer. Interleukin (IL-) 37 is a fundamental inhibitor of innate immunity by reducing systemic and local inflammation. IL-37 protein is expressed in healthy and diseased bowel and liver tissue. Here, we tested whether transgenic expression of human IL-37 protects IL-10 deficient (IL-10KO) mice from chronic colitis. IL-37tg mice were crossbred with IL-10KO mice. Homozygous IL-10KO/IL-37tg and IL10KO drank 2% dextran sulfate sodium (DSS) in water for 5 days to induce mild colitis. Colon carcinogenesis was triggered by intragastric administration of celecoxib. Endpoints were clinical parameters of colitis, cytokine responses in LPS-stimulated whole blood and explanted colon specimen and qPCR analysis of colon biopsies. Colon inflammation and number of adenoma-carcinoma were analyzed by histology. During the DSS-induction phase IL-10KO and IL-10KO/IL-37tg mice had a similar weight loss due to mild acute colitis. From day 115 there was a significantly improved weight gain in IL-10KO/IL37-tg mice, though colon length was similar. After ex vivo LPS stimulation whole blood of IL-10KO/IL-37tg compared to IL-10KO mice released less IL-6, IL-17, IFNγ, and TNFα and ex vivo colon cultures showed reduced IL-6 production both indicative of reduced inflammatory conditions under the influence of IL-37. Six out of 10 IL-10KO mice developed colon adenoma and carcinoma. Only one adenoma but no carcinoma was detected in colons of IL-10KO/IL-37tg mice. In conclusion, IL-37 transgene expression protects IL-10KO mice from colon carcinogenesis. It remains unclear whether IL-37 has direct tumor suppressing properties.

Abstract
BACKGROUND Although various studies have been conducted on colitis-associated cancer (CAC), few have assessed the differences in the clinical and endoscopic features, treatment, and prognosis of CAC and sporadic neoplasia (SN) in the inflamed mucosa of ulcerative colitis (UC) patients. AIMS To compare the characteristics of CAC and SN within the previously or currently inflamed mucosa. METHODS Between 1997 and 2017, we retrospectively analyzed the endoscopic chart data of 348 colonic lesions from 266 UC patients. Non-dysplastic lesions and lesions located outside the inflamed mucosa were excluded. The diagnosis of CAC or SN was confirmed by conventional histopathological and immunohistochemical evaluation of p53 and Ki67. RESULTS In total, 74 patients with CAC (97 lesions) and 46 with SN (58) were enrolled. The proportions of patients with a younger age of onset of UC, with chronic persistent UC, and with severe inflamed mucosa were significantly higher in the CAC group. In the SN group, no flat lesions were found, whereas 26% of the lesions in the CAC group were flat. Sixteen patients died during a median follow-up of 6.1 years (interquartile range (IQR) 1.8-11.1)in the CAC group, whereas 1 patient died during a median follow-up 3.2 years(IQR 1.4-4.6) in the SN group. Mortality from colorectal cancer was significantly higher (P = 0.015) in the CAC group (12/68; 17.6%) than in the SN group (1/44; 2.3%). The 5-year survival rate was 100% in the SN group and 97% in the CAC group for lesions located in the mucosa or submucosa. CONCLUSION Recognizing differences in the characteristics of CAC and SN within the inflamed mucosa is critical to avoid unnecessary total colectomy in patients with SN.

Abstract
These guidelines on the management of primary sclerosing cholangitis (PSC) were commissioned by the British Society of Gastroenterology liver section. The guideline writing committee included medical representatives from hepatology and gastroenterology groups as well as patient representatives from PSC Support. The guidelines aim to support general physicians, gastroenterologists and surgeons in managing adults with PSC or those presenting with similar cholangiopathies which may mimic PSC, such as IgG4 sclerosing cholangitis. It also acts as a reference for patients with PSC to help them understand their own management. Quality of evidence is presented using the AGREE II format. Guidance is meant to be used as a reference rather than for rigid protocol-based care as we understand that management of patients often requires individual patient-centred considerations.

Abstract
Primary sclerosing cholangitis (PSC) is a rare cholestatic liver disease characterized by progressive fibroinflammatory destruction of the intra- and/or extrahepatic biliary ducts. While its features and disease course can be variable, most patients with PSC have concurrent inflammatory bowel disease and will eventually develop liver cirrhosis and end-stage liver disease, with liver transplantation representing the only potentially curative option. Importantly, PSC is associated with a significantly increased risk of malignancy compared to the general population, mainly cholangiocarcinoma, gallbladder carcinoma, hepatocellular carcinoma, and colorectal cancer, with nearly 50% of deaths in patients with PSC being due to cancer. Therefore, robust surveillance strategies are needed, though uncertainty remains regarding how to best do so. In this review, we discuss the epidemiology, prevention, and surveillance of cancers in patients with PSC. Where evidence is limited, we present pragmatic approaches based on currently available data and expert opinion.

Abstract
Primary sclerosing cholangitis (PSC) is a chronic and progressive disease of the biliary tract. PSC is strongly associated with inflammatory bowel disease (IBD), mainly with ulcerative colitis, and most PSC patients have underlying IBD. The pathophysiological interactions between IBD and PSC are unclear, although it seems that the patients with IBD and PSC have a distinct phenotype. IBD with coexisting PSC is more extensive and is characterized by milder activity compared to IBD alone. The coexistence of PSC increases the risk for colorectal cancer in IBD patients and lifelong annual surveillance colonoscopy is recommended. Also, liver transplantation (LT) for PSC may affect the course of IBD. In addition, the management of IBD after LT includes many specific problems. On the other hand, the effect of IBD on the natural history of PSC appears to be milder. However, IBD may increase the risk of postsurgical complications after LT and is a risk factor for recurrent PSC after LT. Overall, the coexistence of IBD with PSC changes the management, natural history and prognosis of both diseases.

Abstract
Background In inflammatory bowel disease (IBD) patients there are reports of the occurrence of hepatobiliary manifestations, so the aim of this study was to evaluate the hepatobiliary manifestations in patients with Crohn's disease (CD) and ulcerative colitis (UC) from an IBD reference center. Methods Cross-sectional study in an IBD reference center, with interviews and review of medical charts, between July 2015 and August 2016. A questionnaire addressing epidemiological and clinical characteristics was used. Results We interviewed 306 patients, and the majority had UC (53.9%) and were female (61.8%). Hepatobiliary manifestations were observed in 60 (19.6%) patients with IBD. In the greater part of the patients (56.7%) hepatobiliary disorders were detected after the diagnosis of IBD. In UC (18.2%) patients, the hepatobiliary disorders identified were 11 (6.7%) non-alcoholic fatty liver disease, 9 (5.5%) cholelithiasis, 6 (3.6%) primary sclerosing cholangitis (PSC), 3 (1.8%) hepatotoxicity associated with azathioprine, 1 (0.6%) hepatitis B, and 1 (0.6%) hepatic fibrosis. In CD (21.3%) patients, 11 (7.8%) had cholelithiasis, 11 (7.8%) non-alcoholic fatty liver disease, 4 (2.8%) PSC, 3 (2.1%) hepatotoxicity, 1 (0.7%) hepatitis B, (0.7%) hepatitis C, 1 (0.7%) alcoholic liver disease, and 1 (0.7%) autoimmune hepatitis (AIH). There was one case of PSC/AIH overlap syndrome. Conclusion The frequency of hepatobiliary disorders was similar in both forms of IBD in patients evaluated. The most common nonspecific hepatobiliary manifestations in IBD patients were non-alcoholic liver disease and cholelithiasis. The most common specific hepatobiliary disorder was PSC in patients with extensive UC or ileocolonic CD involvement; this was seen more frequently in male patients.

Abstract
Primary sclerosing cholangitis (PSC) is a chronic inflammatory liver disease and its frequent complication with ulcerative colitis highlights the pathogenic role of epithelial barrier dysfunction. Intestinal barrier dysfunction has been implicated in the pathogenesis of PSC, yet its underlying mechanism remains unknown. Here, we identify Klebsiella pneumonia in the microbiota of patients with PSC and demonstrate that K. pneumoniae disrupts the epithelial barrier to initiate bacterial translocation and liver inflammatory responses. Gnotobiotic mice inoculated with PSC-derived microbiota exhibited T helper 17 (TH17) cell responses in the liver and increased susceptibility to hepatobiliary injuries. Bacterial culture of mesenteric lymph nodes in these mice isolated K. pneumoniae, Proteus mirabilis and Enterococcus gallinarum, which were prevalently detected in patients with PSC. A bacterial-organoid co-culture system visualized the epithelial-damaging effect of PSC-derived K. pneumoniae that was associated with bacterial translocation and susceptibility to TH17-mediated hepatobiliary injuries. We also show that antibiotic treatment ameliorated the TH17 immune response induced by PSC-derived microbiota. These results highlight the role of pathobionts in intestinal barrier dysfunction and liver inflammation, providing insights into therapeutic strategies for PSC.

Abstract
Primary sclerosing cholangitis (PSC) is a chronic, progressive cholestatic disease that is associated with inflammatory bowel disease (IBD) in approximately 70% of cases. Although the pathogenesis is still unknown for both diseases, there is increasing evidence to indicate that they share a common underlying predisposition. Herein, we review the epidemiology, diagnosis, disease pathogenesis, and specific clinical features of the PSC-IBD phenotype. Patients with PSC-IBD have a distinct IBD phenotype with an increased incidence of pancolitis, backwash ileitis, and rectal sparing. Despite often having extensive colonic involvement, these patients present with mild intestinal symptoms or are even asymptomatic, which can delay the diagnosis of IBD. Although the IBD phenotype has been well characterized in PSC patients, the natural history and disease behavior of PSC in PSC-IBD patients is less well defined. There is conflicting evidence regarding the course of IBD in PSC-IBD patients who receive liver transplantation and their risk of recurrent PSC. IBD may also be associated with an increased risk of cholangiocarcinoma in PSC patients. Overall, the PSC-IBD population has an increased risk of developing colorectal neoplasia compared to the conventional IBD population. Lifelong annual surveillance colonoscopy is currently recommended.

Abstract
BACKGROUND & AIMS Patients with inflammatory bowel disease (IBD) and primary sclerosing cholangitis (PSC, termed PSC-IBD) are at increased risk for colorectal cancer, but their risk following a diagnosis of low-grade dysplasia (LGD) is not well described. We aimed to determine the rate of advanced colorectal neoplasia (aCRN), defined as high-grade dysplasia and/or colorectal cancer, following a diagnosis of indefinite dysplasia or LGD in this population. METHODS We performed a retrospective, longitudinal study of 1911 patients with colonic IBD (293 with PSC and 1618 without PSC) who underwent more than 2 surveillance colonoscopies from 2000 through 2015 in The Netherlands or the United States (9265 patient-years of follow-up evaluation). We collected data on clinical and demographic features of patients, as well as data from each surveillance colonoscopy and histologic report. For each surveillance colonoscopy, the severity of active inflammation was documented. The primary outcome was a diagnosis of aCRN during follow-up evaluation. We also investigated factors associated with aCRN in patients with or without a prior diagnosis of indefinite dysplasia or LGD. RESULTS Patients with PSC-IBD had a 2-fold higher risk of developing aCRN than patients with non-PSC IBD. Mean inflammation scores did not differ significantly between patients with PSC-IBD (0.55) vs patients with non-PSC IBD (0.56) (P = .89), nor did proportions of patients with LGD (21% of patients with PSC-IBD vs 18% of patients with non-PSC IBD) differ significantly (P = .37). However, the rate of aCRN following a diagnosis of LGD was significantly higher in patients with PSC-IBD (8.4 per 100 patient-years) than patients with non-PSC IBD (3.0 per 100 patient-years; P = .01). PSC (adjusted hazard ratio [aHR], 2.01; 95% CI, 1.09-3.71), increasing age (aHR 1.03; 95% CI, 1.01-1.05), and active inflammation (aHR, 2.39; 95% CI, 1.63-3.49) were independent risk factors for aCRN. Dysplasia was more often endoscopically invisible in patients with PSC-IBD than in patients with non-PSC IBD. CONCLUSIONS In a longitudinal study of almost 2000 patients with colonic IBD, PSC remained a strong independent risk factor for aCRN. Once LGD is detected, aCRN develops at a higher rate in patients with PSC and is more often endoscopically invisible than in patients with only IBD. Our findings support recommendations for careful annual colonoscopic surveillance for patients with IBD and PSC, and consideration of colectomy once LGD is detected.

Abstract
Primary sclerosing cholangitis is a rare, chronic cholestatic liver disease characterised by intrahepatic or extrahepatic stricturing, or both, with bile duct fibrosis. Inflammation and fibrosis of bile ducts and the liver are followed by impaired bile formation or flow and progressive liver dysfunction. Patients might be asymptomatic at presentation or might have pruritus, fatigue, right upper quadrant pain, recurrent cholangitis, or sequelae of portal hypertension. The key diagnostic elements are cholestatic liver biochemistry and bile duct stricturing on cholangiography. Genetic and environmental factors are important in the cause of the disease, with the intestinal microbiome increasingly thought to play a pathogenetic role. Approximately 70% of patients have concurrent inflammatory bowel disease and patients require colonoscopic screening and surveillance. Primary sclerosing cholangitis is associated with increased malignancy risk and surveillance strategies for early cholangiocarcinoma detection are limited. No single drug has been proven to improve transplant-free survival. Liver transplantation is effective for advanced disease but at least 25% of patients develop recurrent disease in the graft.

Abstract
Ulcerative colitis is characterized by chronic inflammation, which may lead to the accumulation of high levels of pro-inflammatory cytokines within the colonic mucosa, and thus to dysplastic lesions and cancer. Although the trend is decreasing, ulcerative colitis patients still have a 2.4 fold higher risk of colorectal cancer compared to the general population. The key task is to control colonic inflammation, and a rapid step-up approach while closely monitoring intestinal inflammation are recommented. Surveillance colonoscopy program demonstrated its efficacy for reducing the incidence of colorectal cancer in ulcerative colitis. The impact of medication on the reduction of colorectal cancer risk was hardly investigated and it remains unclear whether they have intrinsic anti-neoplastic properties or only downregulate inflammatory pathways. Several studies showed a decreased risk of colorectal cancer in ulcerative colitis patients treated with 5-aminosalicylic acid and chemoprevention with mesalamine compounds is currently recommended. The current level of evidence is too low for thiopurines and anti-TNFα agents. Large, prospective cohort studies are ongoing and are likely to bring new findings about the impact of drugs on colorectal cancer risk in the current era of biologics.

Abstract
BACKGROUND & AIMS Patients with primary sclerosing cholangitis (PSC) and ulcerative colitis (UC) have a high risk of colonic neoplasia. Neoplasia frequently develops in the proximal colon in patients with PSC. Histologic inflammation is an independent risk factor for the development of neoplasia; we investigated whether patients with UC and PSC have more subclinical disease activity than patients with UC alone. METHODS We performed a retrospective analysis of data from 143 patients (205 examinations) with ulcerative pancolitis who were in clinical remission and treated at a tertiary medical center from May 2011 through May 2016. Endoscopic and histologic activity were compared between patients with PSC (from 36 examinations) and without PSC (from 169 examinations). Disease activity was scored per colonic segment using a modified Mayo endoscopic subscore and histologic assessment. In each colonic segment, differences in disease activity and the degree of discordance between endoscopic and histologic inflammation among UC patients with and without PSC were compared. RESULTS Patients with UC-PSC had significantly more subclinical endoscopic (odds ratio [OR], 4.21; 95% CI, 1.67-10.63) and histologic activity (OR, 5.13; 95% CI, 2.25-11.68) in the right colon, as well as greater degree of histologic than endoscopic inflammation in the proximal colon (OR, 3.14, 95% CI, 1.24-7.97), compared with patients without PSC. Patients with UC-PSC had significantly less histologic activity in the rectum on multivariate analysis (OR, 0.24; 95% CI, 0.08-0.72). CONCLUSIONS Patients with UC and PSC who are in clinical remission are significantly more likely to have endoscopic and histologic inflammation in the right colon than patients with UC without PSC. Our findings provide insight into cause of colorectal cancer in UC patients with PSC.

Abstract
Colorectal cancer (CRC) is a common malignancy worldwide. Some studies suggest that organ recipients are at a higher risk for CRC than the general population. The underlying transplant indications and their inherent risk factors for CRC may drive the variation in incidence rates that are seen in patients receiving different allografts. Recipients with cystic fibrosis are now recognized as a population at high risk for CRC at a young age. Transplant recipients have high mortality following a CRC diagnosis, even if it is detected at an early stage. Certain types of immunosuppression have been shown to accelerate cancer transformation and may contribute to the more aggressive phenotype seen in organ recipients. Given the high incidence and progressive nature of posttransplant CRC, shorter screening intervals with a modality that can detect early-stage polyps may be essential to prevent mortality. Future research is needed to better elucidate the role of immunosuppression in carcinogenesis. This comprehensive review examines CRC risk, screening, and management specific to organ transplant candidates and recipients.

Abstract
INTRODUCTION Colorectal cancer (CRC) is the third most common cancer in males and second in females, and the fourth most common cause of cancer death worldwide. Currently, about 60-70% of diagnosed cases in symptomatic patients are detected at an advanced stage of disease. Earlier stage detection through the use of screening strategies would allow for better outcomes in terms of reducing the disease burden. Areas covered: The aim of this paper is to review the current published evidence from literature which assesses the performance and effectiveness of different screening tests for the early detection of CRC. Expert commentary: Adequate screening strategies can reduce CRC incidence and mortality. In the last few decades, several tests have been proposed for CRC screening. To date, there is still insufficient evidence to identify which approach is definitively superior, and no screening strategy for CRC can therefore be defined as universally ideal. The best strategy would be the one that can be economically viable and to which the patient can adhere best to over time. The latest guidelines suggest colonoscopy every 10 years or annual fecal immuno-chemical test (FIT) for people with normal risk, while for individuals with high risk or hereditary syndromes specific recommendations are provided.

Abstract
Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease which is associated with inflammatory bowel disease (IBD) in most cases. As there is currently no medical therapy which alters the natural history of PSC, liver transplantation may be required. Areas covered: We searched for articles in PubMed and critically reviewed current literature on the interrelationship between PSC and IBD with a specific focus on considerations for patients in the liver transplant setting. Expert commentary: PSC is an uncommon disease which limits available studies to be either retrospective or contain relatively small numbers of patients. Based on observations from these studies, the behavior and complications of PSC and IBD impact on each other both before and after a liver transplant. Both these autoimmune conditions and their associated cancer risk also influence patient selection for transplantation and may be impacted by immunosuppression use post-transplant. Hence, a complex interplay exists between PSC, IBD and liver transplantation which requires clarification with ongoing research.

Abstract
Malignancy represents substantial morbidity and mortality in patients with primary sclerosing cholangitis (PSC). This subset of patients has been proven to be at increased risk for developing cholangiocarcinoma, gallbladder carcinoma and colorectal cancer in those with overlapping inflammatory bowel disease. Herein, we review the prevalence of these malignancies and recommend screening tools and current knowledge to reduce the disease burden in this population. Cholangiocarcinoma is the most dominant malignancy affecting PSC patients, with a lifetime risk ranging from 5% to 20%. We advocate for serial US or MRI/MRCP and CA 19-9 to screen for cholangiocarcinoma. Gallbladder cancer has a lifetime risk around 2% in this population and we agree with annual imaging for lesions as recommended by national guidelines. Patients with PSC and concomitant IBD are at increased risk of colorectal carcinoma from time of diagnosis and therefore should likely undergo annual surveillance. The low rates of hepatocellular cancer and pancreatic cancer indicate surveillance for these malignancies is less advantageous.

Abstract
Primary sclerosing cholangitis (PSC) is a disease of the biliary tract, which has been documented in the literature since 1867. This disease has a strong predilection for affecting men and can be seen in individuals as young as 2 years of age. PSC has a strong associated with inflammatory bowel disease, more commonly with ulcerative colitis, and is also part of the clinical spectrum of IgG4-related diseases. Small-duct PSC, a variant of PSC, also has an association with inflammatory bowel disease. The exact pathogenesis of PSC is not well understood at present, however, is likely a combination of a genetic predisposition with alteration of the molecular structure of the gut. Abnormal serum liver chemistry and presence of certain autoimmune markers are usually the first indicators leading to a diagnosis of PCS, however, these may often be normal in early stages of this disease. The diagnosis is made by cholangiography, which is now considered the gold standard. PSC is a known pre-malignant condition. Such patients have an increased risk of developing cholangiocarcinoma, gallbladder neoplasia, and colon cancer. Many new treatment modalities have emerged in the recent past, including anti-tumor necrosis factor- α and anti-integrins; however, liver transplantation is the only known cure for PSC. Despite past and present research, PSC remains an enigmatic biliary disease with few viable treatment options.

Abstract
CONTEXT -Idiopathic inflammatory bowel disease manifests with different clinical phenotypes showing varying behavior and risk for neoplasia. The clinical questions that are posed to pathologists differ depending on phase of the disease and the clinical circumstances. Understanding the clinical aspects of the dynamic disease process will enhance the role of pathology in optimizing the care of patients with inflammatory bowel disease. OBJECTIVE -To review clinical and surgical aspects of inflammatory bowel disease that are relevant to practicing pathologists. DATA SOURCES -The literature was reviewed. CONCLUSIONS -Diagnosis and management of inflammatory bowel disease require an integrated evaluation of clinical, endoscopic, radiologic, and pathologic features. Therefore, close interaction between clinicians and pathologists is crucial. Having this team approach improves understanding of the pertinent clinical and surgical aspects of the disease and assists in the recognition of unusual presentation of variants, as well as mimics of idiopathic inflammatory bowel disease, by pathologists.

Abstract
BACKGROUND Sclerosing cholangitis (SC) is a chronic cholestatic hepatobiliary disease with uncertain long-term prognosis in pediatric patients. This study aimed to evaluate long-term results in children with SC according to the types of SC. METHODS We retrospectively followed up 25 children with SC over a period of 4-17 years (median 12). The diagnosis of SC was based on biochemical, histological and cholangiographic findings. Patients fulfilling diagnostic criteria for probable or definite autoimmune hepatitis at the time of diagnosis were defined as having autoimmune sclerosing cholangitis (ASC); other patients were included in a group of primary sclerosing cholangitis (PSC). The incidence of the following complications was studied: obstructive cholangitis, portal hypertension, advanced liver disease and death associated with the primary disease. RESULTS Fourteen (56%) patients had PSC and 11 (44%) had ASC. Patients with ASC were significantly younger at the time of diagnosis (12.3 vs 15.4 years, P=0.032) and had higher IgG levels (22.7 vs 17.2 g/L, P=0.003). The mentioned complications occurred in 4 (16%) patients with SC, exclusively in the PSC group: one patient died from colorectal cancer, one patient underwent liver transplantation and two patients, in whom severe bile duct stenosis was present at diagnosis, were endoscopically treated for acute cholangitis. Furthermore, two other children with ASC and 2 children with PSC had elevated aminotransferase levels. The 10-year overall survival was 95.8% in all patients, 100% in patients without complicated liver disease, and 75.0% in patients with complications. CONCLUSION In children, ASC is a frequent type of SC, whose prognosis may be better than that in patients with PSC.

Abstract
BACKGROUND Histomorphology of colitis-associated colorectal cancer (CAC) in patients with primary sclerosing cholangitis (PSC) remains to be systemically characterized and prognosis in these patient needs to be further defined. AIM To examine the impact of PSC on histomorphology and to assess prognosis of CAC-PSC patients. METHODS A cohort of CAC patients were identified from the Pathology Database (1994-2010) at Cleveland Clinic; histomorphological features and other relevant data were collected by retrospective review of pathology slides and medical records. RESULTS A total of 87 CAC patients were included, with 11 patients having PSC (the study group) and 76 patients without PSC (the control group). The overall median follow up was 6 (range: 0-20) years. The patients in the study group had a longer median duration of inflammatory bowel disease prior to CAC diagnosis (p = 0.046). In study group, seven (63.6%) patients had right-sided CAC (vs. 36.8% in the control group, p = 0.11). Background high-grade dysplasia was noted less (9.1% vs. 44.7%), while low-grade dysplasia was detected more in the study group (72.7% vs. 28.9%) (p = 0.02). All histomorphological features were comparable between groups. The overall survival (OS) and progression-free survival (PFS) showed no statistical difference between CAC patients with or without PSC. After excluding TNM stage IV patients, patients with PSC showed a trend toward shorter OS and PFS (p = 0.07 and p = 0.1). CONCLUSION In CAC, histomorphology appeared to be independent of PSC. PSC is associated with a trend toward shorter OS and PFS in CAC patients with stage I-III diseases.

Abstract
Primary sclerosing cholangitis (PSC) is a chronic progressive disease, usually associated with underlying inflammatory bowel diseases (IBDs), with a prevalence of 60-80% in western countries. Herein, we review the current knowledge about the association between PSC and IBD in terms of clinical approach and long-term patient management. A PubMed search was conducted for English-language publications from 2000 through 2015 using the following keywords: primary sclerosing cholangitis, inflammatory bowel disease, ulcerative colitis, Crohn's disease, diagnosis, therapy, follow-up, and epidemiology. In terms of diagnosis, liver function tests and histology are currently used. The medical treatment options for PSC associated with IBD do not differ from the cases of PSC alone, and include ursodeoxycholic acid and immunosuppressive agents. These treatments do not seem to improve survival, even if ursodeoxycholic acid given at low doses may be chemopreventive against colorectal cancer (CRC). Liver transplantation is the only potential curative therapy for PSC with reported survival rates of 85 and 70% at 5 and 10 years after transplant; however, there is a risk for PSC recurrence, worsening of IBD activity, and de-novo IBD occurrence after liver transplantation. PSC-IBD represents an important public health concern, especially in view of the increased risk for malignancy, including CRC. Long-life annual surveillance colonoscopy is usually recommended, although the exact timescale is still unclear. Further studies are required both to clarify whether annual colonoscopy is cost-effective, especially in younger patients, and to identify potential pharmaceutical agents and genetic targets that may retard disease progression and protect against CRC.

Abstract
Primary sclerosing cholangitis (PSC) is a chronic, progressive disease characterized by inflammatory and fibrosing strictures of the biliary tree. PSC is associated with a high lifetime risk of hepatobiliary and colorectal cancers. The nature of the carcinogenic process in PSC is not well established. The lack of diagnostic methods for early detection and the limited therapeutic options for cholangiocarcinoma constitute a major challenge in the current handling of PSC patients. The article reviews the risk for cancer development in PSC and discusses surveillance strategies for PSC-associated cancers.

Abstract
Ulcerative colitis (UC) is an important risk factor for colorectal cancer (CRC). Histone modifications are one of the epigenetic mechanisms that may have key roles in the carcinogenesis of CRC. At present, there are no studies comparing histone modification patterns of UC and CRC in the literature. Therefore the aim of the present study was to investigate whether genes, particularly those involved in histone modification, have value in patient monitoring with regards to CRC development in UC. Key gene expressions of the histone modification enzyme were assessed and compared in CRC, UC and control groups using the RT-PCR array technique. Patients were divided into subgroups based on the extent and duration of the disease and inflammatory burden, which are considered risk factors for CRC development in UC patients. In UC and CRC groups, a significantly higher overexpression of the NEK6 and AURKA genes compared to the control group was identified. In addition, there was a significantly higher overexpression of HDAC1 and PAK1 genes in the UC group, and of HDAC1, HDAC7, PAK1 and AURKB genes in the CRC group. NEK6, AURKA, HDAC1 and PAK1 were significantly overexpressed in patients with a longer UC duration. Overexpression of AURKA and NEK6 genes was significantly more pronounced in UC patients with more extensive colon involvement. HDAC1, HDAC7, PAK1, NEK6, AURKA and AURKB are important diagnostic and prognostic markers involved in the carcinogenesis of CRC. HDAC1, PAK1, NEK6 and AURKA may be considered as diagnostic markers to be used in CRC screening for UC patients.

Abstract
Inflammatory bowel diseases (IBDs) include both Crohn's disease and ulcerative colitis and both diseases are marked by inflammation within the gastrointestinal tract. Due to long-standing inflammation, IBD patients are at increased risk of colorectal cancer, especially patients with chronic inflammation, pancolitis, co-diagnosis of primary sclerosing cholangitis and a longer duration of disease. Small bowel inflammation places Crohn's patients at an increased risk of small bowel cancer. A higher risk of skin cancers, lymphomas and cervical abnormalities is also seen in IBD patients; this is likely related to both disease factors and the presence of immunosuppressive medication. This article reviews which patients are at an increased risk of IBD-associated or IBD treatment-associated cancers, when to begin screening and which screening methods are recommended.

Abstract
OBJECTIVE Inflammatory bowel disease (IBD) patients with concomitant primary sclerosing cholangitis (PSC) carry an increased risk of colorectal cancer (CRC) and cholangiocarcinoma (CCA). We evaluated the relative risk of these malignancies in IBD patients with PSC, who had been under regular surveillance. MATERIAL AND METHODS The survey involved a cohort of 51 patients with IBD and concomitant PSC. All patients had been under regular surveillance for a median of 19 years. The standardized incidence ratios (SIRs) of CRC and CCA were estimated between 1986 and 2007. RESULTS During the follow up, three patients (5.9%) developed CRC and five patients (9.8%) developed CCA. SIRs were 20.71 (95% confidence interval [CI]: 5.62-79.70) and 916.63 (95% CI: 297.88-2140.99), respectively. The median age at diagnosis of CRC was 39.5 years. All patients with PSC were <45 years of age at the time of detecting CRC and had other risk factors for CRC. The median age at the time of the CCA diagnosis was 54.0 years. CONCLUSION Despite regular surveillance, the relative risks of CCA and CRC remained increased in patients with IBD and PSC. A rigorous endoscopic surveillance is maintained for all patients with PSC, but better indicators of the development of CCA are urgently needed.

Abstract
BACKGROUND AND AIM Ulcerative colitis increases the risk of developing dysplasia and colitis-associated cancer (CAC). The purpose of this study was to determine the risk factors as well as protective measures for disease burden, need for colectomy and the development of CAC in ulcerative colitis (UC) patients. METHODS A cohort of n = 434 UC patients was evaluated. Data analysis was performed by univariate and multivariate logistic regression. Odds ratios (OR) and 95 % confidence intervals (CI) were calculated, and significance was assessed by the likelihood ratio test. RESULTS Mean patient age at UC diagnosis was 45.7 ± 15.1 years which manifested mainly as pancolitis (47 %) or left-sided colitis (45.2 %). CAC was detected in ten patients (2.3 %). UC disease duration was strongly associated with the risk of CAC (P < 0.0014); disease duration between 9 and 15 years: OR of 2.5 (95 % CI 0.2-41.1), more than 15 years: OR of 21.4 (95 % CI 2.6-173.6). The risk of developing dysplasia (low-grade intraepithelial neoplasia, LGIEN and high-grade intraepithelial neoplasia, HGIEN) or the need to undergo colectomy was also significantly related to disease duration (P = 0.006, P = 0.002, respectively). Established anti-inflammatory medication (e.g., 5-ASA, anti-TNF-α) significantly reduced the risk of both dysplasia and CAC (P = 0.02). CONCLUSIONS Despite the use of modern therapies for UC, CAC rates remain high. In our study, risk factors included disease duration while anti-inflammatory therapies reduced the risk. Effective control of the intestinal inflammation also reduced the disease burden as indicated by decreased risk of requiring colectomy, underscoring the need for sufficient surveillance and anti-inflammatory therapies.
