Introduction: The incidence of endoscopic recurrence (ER) in Crohn's disease following curative resection is up to 75% at 1 year. Endoscopy is the most sensitive method to detect the earliest mucosal changes and the severe ER at 1 year seems to predict a clinical relapse. Methods: The aim of this prospective study was to evaluate the incidence of early ER 6 months after curative resection. Secondary outcome was to evaluate the role of 5-aminosalicylic acid (5-ASA) in the prevention of ER at 6 months. A total of 170 patients were included in the study. They were carried-out from the evaluation of the appearance of ER during a trial performed to assess the role of azathioprine vs. 5-ASA as early treatment of severe ER. All the patients started 5-ASA treatment 2 weeks after surgery. Results: Six months after surgery ER was observed in 105 patients (62%). The endoscopic score was reported as severe in 78.1% of them (82 out of 105). At univariable analysis only ileo-colonic disease influenced the final outcome associating to a lower risk of severe ER (p = 0.04; OR 0.52, 95% CI 0.277-0.974). Conclusion: In this prospective Italian multicenter IG-IBD study a great proportion of ER occur within 6 months from ileo-colonic resection, with a significant rate of severe ER. Furthermore this study confirms the marginal role of 5-ASA in the prevention of ER. This suggests that post-surgical endoscopic evaluation should be performed at 6 months instead of 1 year to allow an adequate early treatment.
Apheresis in Inflammatory Bowel Disease: Current Evidence
Crohn’s disease – Recent Advances [Working Title]
Inflammatory bowel diseases (IBD) have become a major focus for gastroenterologists worldwide, with the increasing incidence and complexity of cases, which pose therapeutic challenges. Currently available approaches fail in controlling the disease activity in a significant proportion of patients and some of the therapies are associated with significant adverse events. Although new molecules are on the horizon and treatment strategies have been optimized, novel therapeutic tools are much needed in IBD for patients who fail to attain control of the disease. Apheresis is now a common non-pharmacological therapeutic modality used in several pathologies, IBD also. In the current review, we summarize currently available evidence with respect to selective apheresis in IBD.

Background Several small, prospective, open studies suggest that leukocytapheresis might be efficient in patients with steroid-dependent ulcerative colitis (UC). Aim To evaluate the short-and long-term effectiveness of leukocytapheresis for the management of steroid-dependent UC in clinical practice. Methods A Web-based, nationwide database specifically designed to record the efficacy and safety data of leukocytapheresis therapy in UC was available from September 2007 in Spain. Clinical data were collected at treatment baseline, 1 month after the last apheresis session (initial efficacy), and 6 and 12 months thereafter (long-term efficacy). Remission was defined as a Mayo Clinic index B2 together with complete steroid withdrawal and response as a decrease of C3 from the baseline score. Results A total of 142 steroid-dependent UC patients were included in the registry, most of them treated with the Adacolumn TM system. In 69% of patients thiopurine therapy failed to achieve steroid-free clinical remission. Initial clinical remission was obtained in 37% of cases. The initial corticosteroid dose, the number and frequency of apheresis sessions, or the previous failure of thiopurines and/or infliximab did not influence the initial remission rate, but a greater decrease in CRP levels was associated with a higher probability to obtain initial remission. At 6 and 12 months, 41 and 36% of patients were in clinical remission, respectively. Only one serious adverse effect was recorded. Conclusions In clinical practice, apheresis allows longterm steroid-free clinical remission in up to one third of steroid-dependent UC patients, even in those with prior failure of thiopurines.

AIM: To investigate gene variants in a large Italian inflammatory bowel disease (IBD) cohort, and to analyze the correlation of sub-phenotypes (including age at diagnosis) and epistatic interaction with other IBD genes. METHODS: Total of 763 patients with Crohn's disease (CD, 189 diagnosed at age < 19 years), 843 with ulcerative colitis (UC, 179 diagnosed < 19 years), 749 healthy controls, and 546 healthy parents (273 trios) were included in the study. The rs2241880 [autophagy-related 16-like 1 (ATG16L1)], rs11209026 and rs7517847 [interleukin 23 receptor (IL23R)], rs2066844, rs2066845, rs2066847 (CARD15), rs1050152 (OCTN1), and rs2631367 (OCTN2) gene variants were genotyped. RESULTS: The frequency of G allele of ATG16L1 SNP (Ala197Thr) was increased in patients with CD compared with controls (59% vs 54% respectively) (OR = 1.25, CI = 1.08-1.45, P = 0.003), but not in UC (55%). The frequency of A and G (minor) alleles of Arg381Gln, rs11209026 and rs7517847 variants of IL23R were reduced significantly in CD (4%, OR = 0.62, CI = 0.45-0.87, P = 0.005; 28%, OR = 0.64, CI = 0.55-0.75, P < 0.01), compared with controls (6% and 38%, respectively). The A allele (but not G) was also reduced significantly in UC (4%, OR = 0.69, CI = 0.5-0.94, P = 0.019). No association was demonstrated with sub-phenotypes and interaction with CARD15 , and OCTN1/2 genes, although both gene variants were associated with pediatric-onset disease. CONCLUSION: The present study confirms the association of IL23R polymorphisms with IBD, and ATG16L1 with CD, in both adult-and pediatric-onset subsets in our study population.
Association Study of a Polymorphism in Clock Gene PERIOD3 and Risk of Inflammatory Bowel Disease
Chronobiology International, 2012
Altered body rhythmicity and deregulated clock gene expression may cause circadian disruption, which can lead to immune dysregulation and chronic inflammatory diseases. PERIOD3 (PER3) polymorphisms have been associated with circadian disruption and changed secretion of cytokines involved in chronic inflammation. Crohn's disease (CD) and ulcerative colitis (UC) are multifactorial diseases resulting from complex interaction among environmental/ microbial factors and the intestinal immune system, triggering an abnormal immune response in genetically susceptible individuals. We evaluated the influence of a polymorphism of the clock gene PER3 on susceptibility and behavior of these inflammatory bowel diseases. The rs2797685 variant of the PER3 gene was assessed in 1082 CD and 972 UC patients, 754 of whom had been diagnosed <18 yrs of age, and 1311 unrelated healthy controls. Allele and genotype frequencies of rs2797685 were significantly increased in both CD ( p = 1.6 × 10 −4 , odds ratio [OR] = 1.38, 95% confidence interval [CI]: 1.17-1.63) and UC ( p = .012, OR = 1.25, 95% CI: 1.05-1.48) patients. Difference between frequency distributions remained statistically significant after stratifying the cohort according to age at diagnosis for CD, but not for UC. Statistically significant association was found between PER3 polymorphism and use of immunosuppressive drugs in pediatric CD patients ( p < .001) and with stricturing and fistulizing disease behavior in adult CD patients ( p = .031). In conclusion, results of this association study suggest a possible role of PER3 polymorphism in determining susceptibility to CD and UC and phenotypic characteristics of CD. In particular, the rs2797685 variant of the PER3 gene is associated with a more aggressive form of CD, highlighted by higher use of immunosuppressants and more frequent stricturing and fistulizing disease behaviors, as well as early onset of CD. This is a descriptive study, and functional data are needed to prove a causal relationship; nonetheless, involvement of the clock gene machinery in the susceptibility and the behavior of inflammatory bowel diseases may suggest new pathophysiological mechanisms and new therapeutic approaches.

Background and Aims: Endoscopic outcomes are increasingly used in clinical trials and in routine practice for inflammatory bowel disease [IBD] in order to reach more objective patient evaluations than possible using only clinical features. However, reproducibility of endoscopic scoring systems used to categorize endoscopic activity has been reported to be suboptimal. The aim of this study was to analyse the inter-rated agreement of non-dedicated gastroenterologists on IBD endoscopic scoring systems, and to explore the effects of a dedicated training programme on agreement. Methods: A total of 237 physicians attended training courses on IBD endoscopic scoring systems, and they independently scored a set of IBD endoscopic videos for ulcerative colitis [with Mayo endoscopic subscore], post-operative Crohn's disease [with Rutgeerts score] and luminal Crohn's disease (with the Simple Endoscopic Score for Crohn's Disease [SESCD] and Crohn's Endoscopic Index of Severity [CDEIS]). A second round of scoring was collected after discussion about

Inflammatory bowel disease registries for collection of patient iron parameters in Europe
World Journal of Gastroenterology
Iron deficiency without anemia and iron deficiency anemia are common and frequently overlooked complications of inflammatory bowel disease. Despite the frequency and impact of iron deficiency in inflammatory bowel disease, there are gaps in our understanding about its incidence, prevalence and natural history and, consequently, patients may be undertreated. Medical registries have a key role in collecting data on the disease's natural history, the safety and effectiveness of drugs in routine clinical practice, and the quality of care delivered by healthcare services. Even though iron deficiency impacts inflammatory bowel disease patients and healthcare systems substantially, none of the established European inflammatory bowel disease registries systematically collects information on iron parameters and related outcomes. Collection of robust iron parameter data from patient registries is one way to heighten awareness about the importance of iron deficiency in this disease and to generate data to improve the quality of patient care, patient outcomes, and thus quality of life. This objective could be achieved through collection of specific laboratory, clinical, and patient-MINIREVIEWS 1063 March 14, 2018|Volume 24|Issue 10| WJG|www.wjgnet.com
Role of CARD15, DLG5 and OCTN genes polymorphisms in children with inflammatory bowel diseases
World journal of gastroenterology : WJG, 2007
To investigate the contribution of variants of CARD15, OCTN1/2 and DLG5 genes in disease predisposition and phenotypes in a large Italian cohort of pediatric patients with inflammatory bowel diseases (IBD). Two hundred patients with Crohn's disease (CD), 186 ulcerative colitis (UC) patients, 434 parents (217 trios), and 347 healthy controls (HC) were studied. Polymorphisms of the three major variants of CARD15, 1672C/T and -207G/C SNPs for OCTN genes, IGR2096a_1 and IGR2198a_1 SNPs for the IBD5 locus, and 113G/A variant of the DLG5 gene were evaluated. Potential correlations with clinical sub-phenotypes were investigated. Polymorphisms of CARD15 were significantly associated with CD, and at least one variant was found in 38% of patients (15% in HC, OR = 2.7, P < 0.001). Homozygosis for both OCTN1/2 variants was more common in CD patients (1672TT 24%, -207CC 29%) than in HC (16% and 21%, respectively; P = 0.03), with an increased frequency of the TC haplotype (44.8% vs 38.3% i...
