AbstractRates of anastomotic leak following intestinal resections in the setting of inflammatory bowel disease are significantly influenced by clinical characteristics. While the literature can be contradictory due to significant heterogeneity in the published data, several common themes appear to consistently arise. With respect to Crohn's disease, low serum albumin, preoperative abscess, reoperative abdominal surgery, and steroid use are associated with an increased risk of postoperative intra-abdominal septic complications. On the contrary, biologic therapy, immunomodulator use, and method of anastomosis appear not to confer increased anastomotic-related complications. Undoubtedly, a low rate of anastomotic leakage is inherent to procedures within colorectal surgery but diligent attention must be paid to identify, optimize, and, therefore, reduce known risks.

BACKGROUND/OBJECTIVE: Variants in the interleukin-23 receptor (IL23R) and the autophagy-related 16-like 1 (ATG16L1) genes have been associated with an increased risk of Crohn’s disease (CD). Both genes were identified through genome-wide association scans and subsequent studies have validated these associations. To assess the effect size of these variants, an independent case-control association study and meta-analysis were performed.METHODS: British Caucasian subjects with inflammatory bowel disease (n=500) and 877 ethnically matched controls were genotyped for the disease-associated variants inIL23RandATG16L1. In addition, meta-analyses of 12,991 patients and 14,598 controls, and 11,909 patients and 15,798 controls, were conducted on independently published data for the associations betweenIL23RandATG16L1variants and CD, respectively.RESULTS: In the present cohort, both susceptibility variants showed highly significant associations, includingIL23R(rs11209026, P=0.0006; OR 0.37; 95% CI 0.21 to 0.67) andATG16L1(rs2241880, P=0.0017; OR 1.36; 95% CI 1.12 to 1.66). The meta-analysis based on the random effects model showed similar combined effects for rs11209026 (n=26, OR 0.41; 95% CI 0.37 to 0.46) and rs2241880 (n=25, OR 1.33; 95% CI 1.28 to 1.39). There was no statistically significant gene-gene interaction between caspase recruitment domain (CARD15) variants and theIL23RorATG16L1polymorphisms (P=0.44 and P=0.24, respectively).CONCLUSION: The present cohort and meta-analysis provides strong evidence that, in addition toCARD15, polymorphisms in bothIL23RandATG16L1alter susceptibility to CD and that these effects are consistent across all populations of European ancestry; however, onlyATG16L1is relevant to inflammatory bowel disease in the Asian population.

ContextData from Asian populations about gender-related differences in Crohn’s disease are few.ObjectivesThis study was to analyze the clinical characteristics between women and men affected by Crohn’s disease.MethodsThis was a retrospective cohort study to analyze consecutive Crohn’s disease patients from Jan 2000 to Dec 2012. Clinical and phenotypic characteristics and treatment outcomes were evaluated.Results79 patients (55 male and two of them with positive family history) were diagnosed with Crohn’s disease. Ileocolonic disease and inflammatory lesion was the most dominant site of involvement and disease behavior respectively in both men and women. Apart from higher frequency of nausea (45.83 vs 23.64%, P 0.024) and lower body mass index (19.44 vs 22.03 kg/m2, P 0.003) reported in women, no significant gender-related differences in clinical characteristics were observed. Women were more associated with delay use of immunosuppressive therapy (12 vs 36 months, P = 0.028), particularly for those aged less than 40 years old (85 vs 62.6%,P = 0.023). Cox proportional hazard regression analysis revealed that active smoking (HR, 4.679; 95% CI, 1.03-21.18) and delayed use of immunosuppressive therapy (HR, 4.13; 95% CI, 1.01-16.88) were only independent risk factors associated with increased risk of complications.ConclusionsThere were no significant gender-specific differences in clinical and phenotypic characteristics between male and female Crohn’s disease patients. Smoking history and delay use of immunosuppressive therapy were associated with higher risk of complications.

Summary Background: There is an impression mostly from specialty clinics that patients with inflammatory bowel disease (IBD) have an increased risk of venous thromboembolic disorders. Our aim was to determine the incidence of deep venous thrombosis (DVT) and pulmonary embolism (PE) from a population-based database of IBD patients and, to compare the incidence rates to that of an age, gender and geographically matched population control group. Methods: IBD patients identified from the administrative claims data of the universal provincial insurance plan of Manitoba were matched 1:10 to randomly selected members of the general population without IBD by year, age, gender, and postal area of residence using Manitoba Health’s population registry. The incidence of hospitalization for DVT and PE was calculated from hospital discharge abstracts using ICD-9-CM codes 451.1, 453.x for DVT and 415.1x for PE. Rates were calculated based on person-years of follow-up for 1984-1997. Comparisons to the population cohort yielded age-adjusted incidence rate ratios (IRR). Rates were calculated based on person-years of follow-up (Crohn’s disease = 21,340, ulcerative colitis = 19,665) for 1984-1997. Results: In Crohn’s disease the incidence rate of DVT was 31.4/10,000 person-years and of PE was 10.3/10,000 person-years. In ulcerative colitis the incidence rates were 30.0/10,000 person-years for DVT and 19.8/10,000 person-years for PE. The IRR was 4.7 (95% CI, 3.5-6.3) for DVT and 2.9 (1.8-4.7) for PE in Crohn’s disease and 2.8 (2.1-3.7) for DVT and 3.6 (2.5-5.2) for PE, in ulcerative colitis. There were no gender differences for IRR. The highest rates of DVT and PE were seen among patients over 60 years old; however the highest IRR for these events were among patients less than 40 years. Conclusion: IBD patients have a threefold increased risk of developing DVT or PE.

Abstract Background The inflammatory bowel diseases [IBD], including Crohn’s disease [CD] and ulcerative colitis [UC], frequently lead to bowel surgery. Hypoalbuminaemia has been shown to be a prognostic factor for outcomes following surgery for other indications, and we sought to determine its role in predicting IBD-related postoperative outcomes. Methods We included patients who underwent IBD-related major abdominal surgery in the American College of Surgeons’ National Surgical Quality Improvement Program [ACS-NSQIP] between 2005 and 2012. We assessed the impact of indicators of protein-energy malnutrition [PEM] including hypoalbuminaemia, weight loss, and body mass index on postoperative outcomes. Results We identified 10 913 IBD patients [6082 Crohn’s disease and 4831 ulcerative colitis] who underwent bowel surgery. The prevalence of modest and severe hypoalbuminaemia was 17% and 24%, respectively; 30-day mortality was higher in Crohn’s patients with modest and severe hypoalbuminaemia compared with those with normal albumin levels preoperatively [0.7% vs 0.2%, p <0.05; 2.4% vs 0.2%, p <0.01]. The same was true for patients with UC with modest and severe hypoalbuminaemia [0.9% vs 0.1%, p <0.01; 5.6% vs 0.1%, p <0.01]. Overall infectious complications were more common in the presence of severe hypoalbuminaemia for CD [20% vs 13%, p <0.01]. and UC [28% vs 15%, p <0.01] patients. Last, there were higher rates of extra-intestinal, non-septic complications in both CD and UC patients with hypoalbuminaemia compared with those with normal albumin levels. Conclusions This study suggests that moderate-severe hypoalbuminaemia is associated with worse IBD-related postoperative outcomes and may have a role in preoperative risk stratification.

Abstract Background and Aims It is unclear whether pre-pouch ileitis heralds an aggressive inflammatory pouch disease in patients with ileal-pouch anal anastomosis (IPAA). We compared outcomes of patients with pouchitis and concomitant pre-pouch ileitis to those with pouchitis alone. Methods Patients undergoing IPAA surgery for inflammatory bowel disease who subsequently developed pouchitis with concomitant pre-pouch ileitis (pre-pouch ileitis group) were matched by year of IPAA surgery and pre-operative diagnosis (ulcerative colitis or inflammatory bowel disease-unclassified) with patients who developed pouchitis alone (pouchitis group). Primary outcomes were development of Crohn’s disease (CD)-like complications (non-anastomotic strictures or perianal disease &gt;6 months after ileostomy closure) and pouch failure. Secondary outcomes were need for surgical/endoscopic interventions and immunosuppressive therapy. Log-rank test was used to compare outcome-free survival and Cox regression was performed to identify predictors of outcomes. Results There were 66 patients in each group. CD-like complications and pouch failure developed in 36.4% and 7.6% patients in pre-pouch ileitis group and 10.6% and 1.5% in pouchitis group, respectively. CD-like complications-free survival (log-rank p=0.0002) and pouch failure-free survival (log-rank p=0.046) were significantly lower in the pre-pouch ileitis group. Pre-pouch ileitis group had a higher risk of requiring surgical/endoscopic interventions (log-rank p=0.0005) and immunosuppressive therapy (log-rank p&lt;0.0001). Pre-pouch ileitis was independently associated with an increased risk of CD-like complications (HR 3.8; p=0.0007), need for surgical/endoscopic interventions (HR 4.1; p=0.002) and immunosuppressive therapy (HR 5.0; p=0.0002). Conclusions Pre-pouch ileitis is associated with a higher risk of complicated disease and pouch failure than pouchitis. It should be considered a feature of CD.

Introduction: Epitheloid granulomas are one of the best histological criteria for distinguishing Crohn’s disease from other inflammatory bowel diseases. However, the role of granuloma in the pathogenesis and clinical characteristics of Crohn’s disease is unclear. Aim: The aim of the present study was to evaluate the frequency of granulomas and their association with clinical characteristics using the database of the Hungarian Pediatric Inflammatory Bowel Disease Registry. Method: Three hundred and sixty-eight children with Crohn’s disease were registered between January 1st, 2007 and December 31st, 2010. Results: The frequency of granulomas was 31.4% (111/353) at diagnosis. Isolated granuloma in the upper gastrointestinal tract was detected in 2.5% of patients, while those in the terminal ileum was found in 5% of patients. There was no difference in location, behavior and disease activity indexes between patients with and without granulomas. Need for immunomodulators and biological therapy was similar in the two groups in the first year of diagnosis. Conclusions: The frequency of granulomas in this cohort was comparable to the frequency reported in other studies. Interestingly, granulomas in the terminal ileum or upper gastrointestinal tract contributed to the diagnosis of Crohn’s disease in one of 13 children. These data indicate that multiple biopsies from multiple sites are essential for the diagnosis of pediatric Crohn’s disease. Orv. Hetil., 154 (43), 1702–1708.

There is an increased risk of cancer in both ulcerative colitis and Crohn's disease. In 3121 patients with ulcerative colitis, 225 cases of cancer were diagnosed compared with 142.1 expected (standardized incidence ratio [SIR] 1.6, 95% CI 1.4 to 1.8), and in 1655 patients with Crohn's disease, 58 cases of cancer were detected compared with 47.1 expected (SIR 1.2, 95% CI 0.9 to 1.6). After excluding colorectal cancer the observed number of malignancies was very close to that expected for ulcerative colitis (SIR 1.0, 95% CI 0.9 to 1.2) and for Crohn's disease (SIR 1.1, 95% CI 0.8 to 1.5). Thus, the increased risk of cancer in inflammatory bowel disease is confined to colorectal cancer. In Crohn's disease 12 cases of colorectal cancer were observed (SIR 2.5, 95% CI 1.3 to 4.3). The increased risk was confined to those with colonic involvement and young age at diagnosis. In patients with colonic involvement and younger than age 30 years at diagnosis, the SIR was 20.9 (95% CI 6.8 to 48.7) versus 2.2 for those older than 30 years at diagnosis (95% CI 0.6 to 5.7). In ulcerative colitis 91 cases of colorectal cancer were observed with an SIR of 5.7 (95% CI 4.6 to 7.0). Extensive disease and young age at diagnosis were independent risk factors. Pancolitis at diagnosis resulted in an SIR of 14.8 (95% CI 11.4 to 18.9), 2.8 in left-sided colitis (95% CI 1.6 to 4.4) and 1.7 in proctitis (95% CI 0.8 to 3.2). There is great variation in the risk estimates in different studies worldwide. Different treatment strategies could be an explanation, a hypothesis that was substantiated in a study of 102 cases of colorectal cancer among patients with ulcerative colitis compared with 196 controls. Pharmacological therapy with sulfasalazine entailed a strong protective effect against colorectal cancer (relative risk of 0.34, 95% CI 0.190 to 0.62).

Crohn’s disease (CD) is a chronic relapsing disorder of the gastrointestinal tract and represents one of the main entities of inflammatory bowel disease (IBD). CD affects genetically susceptible patients that are influenced by environmental factors and the intestinal microbiome, which results in excessive activation of the mucosal immune system and aberrant cytokine responses. Various studies have implicated the pro-inflammatory cytokines IL17 and IL23 in the pathogenesis of CD. IL23 is a member of the IL12 family of cytokines and is able to enhance and affect the expansion of pathogenic T helper type 17 (Th17) cells through various mechanisms, including maintenance of Th17 signature genes, upregulation of effector genes or suppression of repressive factors. Moreover, IL17 and IL23 signaling is able to induce a cascade of pro-inflammatory molecules like TNF, IFNγ, IL22, lymphotoxin, IL1β and lipopolysaccharide (LPS). Here, IL17A and TNF are known to mediate signaling synergistically to drive expression of inflammatory genes. Recent advances in understanding the immunopathogenetic mechanisms underlying CD have led to the development of new biological therapies that selectively intervene and inhibit inflammatory processes caused by pro-inflammatory mediators like IL17 and IL23. Recently published data demonstrate that treatment with selective IL23 inhibitors lead to markedly high response rates in the cohort of CD patients that failed previous anti-TNF therapy. Macrophages are considered as a main source of IL23 in the intestine and are supposed to play a key role in the molecular crosstalk with T cell subsets and innate lymphoid cells in the gut. The following review focuses on mechanisms, pathways and specific therapies in Crohn’s disease underlying the IL23/IL17 pathway.
