BACKGROUND AND AIMS: Patients with inflammatory bowel disease (IBD) have an increased risk of colorectal cancer (CRC). We performed a systematic review and meta-analysis to identify all prognostic factors for advanced colorectal neoplasia (aCRN, high-grade dysplasia or Q5 CRC) in patients with IBD. METHODS: A systematic literature search was conducted according to the MOOSE Q6 guidelines. Risk of bias was assessed using the Quality in Prognostic Studies tool. Random-effects models were created separately for odds and hazard ratios, different study designs, and univariable or multivariable data. The evidence for all prognostic factors was categorized as Q7 'weak,' 'moderate,' or 'strong,' based on estimate of effect sizes, heterogeneity, and risk of bias. RESULTS: A total of 164 studies were included allowing Q8 pooled analysis of 31 potential prognostic factors. In the univariable analysis, the evidence for extensive disease was classified as strong while evidence for low-grade dysplasia, strictures, primary sclerosing cholangitis, post Q9 -inflammatory polyps, family history of CRC, and ulcerative colitis versus Crohn's disease was considered moderate. Evidence for any dysplasia, colon segment resection, aneuploidy, male sex Q10 and age was classified as weak. In addition, histologic inflammation was identified as a risk factor in multivariable analysis (weak evidence). The evidence for the protective factors colonoscopic surveillance, 5-ASA Q11 , thiopurines, and smoking was moderate in univariable analysis. Multivariable analysis provided weak evidence for statin use. CONCLUSIONS: In this systematic review and meta-analysis Q12 we identified 13 risk factors and 5 protective factors for aCRN in IBD patients, based

Integrative reminiscence within a narrative therapeutic framework may be an effective intervention for enhancing meaning in life with depressed older adults. The intervention has to be developed further and should then be studied in a randomized controlled trial with a larger sample and with follow-up measurements.

Background and Aims There is paucity of data on safety and efficacy of anti-tumour necrosis factor [TNF] in elderly inflammatory bowel disease [IBD] patients. We aimed to compare the long-term treatment failure rates and safety of a first anti-TNF agent in IBD patients between different age groups [<40 years/40–59 years/≥60 years]. Methods IBD patients who started a first anti-TNF agent were identified through IBDREAM, a multicentre prospective IBD registry. Competing risk regression was used to study treatment failure, defined as time to drug discontinuation due to adverse events [AEs] or lack of effectiveness, with discontinuation due to remission as a competing risk. Results A total of 895 IBD patients were included; 546 started anti-TNF at age <40 [61.0%], 268 at age 40–59 [29.9%], and 81 at age ≥60 [9.1%]. Treatment failure rate was higher in the two older groups (subhazard rate [SHR] age ≥60 1.46, SHR age 40–59 1.21; p = 0.03). The SHR in the elderly [>60] was 1.52 for discontinuation due to AEs and 1.11 for lack of effectiveness. Concomitant thiopurine use was associated with a lower treatment failure rate (SHR 0.78, 95% confidence interval [CI] 0.62–0.98, p = 0.031). Serious adverse event [SAE] rate, as well as serious infection rate, were significantly higher in elderly IBD patients [61.2 versus 16.0 and 12.4 per 1000 patient-years, respectively] whereas the malignancy rate was low in all age groups. Conclusions Elderly IBD patients starting a first anti-TNF agent showed higher treatment failure rates, but concomitant thiopurine use at baseline was associated with lower failure rates. Elderly IBD patients demonstrated higher rates of SAEs and serious infections.

Aetiology is presented as a new risk factor associated with PLD severity. Young females with ADPKD represent a subgroup of PLD patients with the most severe phenotype expressed in hTLV.

Background and AimsThe long-term risk of high-grade dysplasia [HGD] and colorectal cancer [CRC] following low-grade dysplasia [LGD] in inflammatory bowel disease [IBD] patients is relatively unknown. We aimed to determine the long-term cumulative incidence of advanced neoplasia [HGD and/or CRC], and to identify risk factors for advanced neoplasia in a nationwide IBD cohort with a history of LGD.MethodsThis is a nationwide cohort study using data from the Dutch National Pathology Registry [PALGA] to identify all IBD patients with LGD between 1991 and 2010 in the Netherlands. Follow-up data were collected until January 2016. We determined the cumulative incidence of advanced neoplasia and identified risk factors via multivariable Cox regression analysis.ResultsWe identified 4284 patients with colonic LGD with a median follow-up of 6.4 years after initial LGD diagnosis. The cumulative incidence of subsequent advanced neoplasia was 3.6, 8.5, 14.4 and 21.7%, after 1, 5, 10 and 15 years, respectively. The median time to develop advanced neoplasia after LGD was 3.6 years. Older age [≥ 55 years] at moment of LGD (hazard ratio [HR] 1.73, 95% confidence interval [CI] 1.44–2.06), male sex [HR 1.33, 95% CI 1.10–1.60], and follow-up at an academic [vs non-academic] medical centre [HR 1.37, 95% CI 1.07–1.76] were independent risk factors for advanced neoplasia following LGD.ConclusionsIn a large nationwide cohort with long-term follow-up of IBD patients with LGD, the cumulative incidence of advanced neoplasia was 21.7% after 15 years. Older age at LGD [≥55 years], male sex and follow-up by a tertiary IBD referral centre were independent risk factors for advanced neoplasia development after initial LGD.

Background Patients with inflammatory bowel disease (IBD) who have postinflammatory polyps (PIPs) may have an increased risk of developing colorectal neoplasia. Current guidelines recommend an intensified surveillance strategy in these patients, although the evidence for this recommendation is conflicting. The aim of our study was to assess whether IBD patients with PIPs are at increased risk of colorectal neoplasia. Methods We established a retrospective cohort in a tertiary IBD center with IBD patients undergoing colorectal cancer (CRC) surveillance in the current era. We compared cumulative incidences of colorectal neoplasia since IBD diagnosis between patients with and without PIPs and corrected for confounders. Second, we compared the risk of receiving a colectomy. Results In our cohort with >22 years of median follow-up, 154 of 519 patients had PIPs. PIPs were associated with extensive disease (odds ratio [OR], 2.76; 95% confidence interval [CI], 1.61–4.42; P < 0.001) and with more severe inflammation at colonoscopy (OR, 3.54; 95% CI, 2.28–5.50; P < 0.001). After correction for confounders, the presence of PIPs was not associated with development of colorectal neoplasia (hazard ratio [HR], 1.28; 95% CI, 0.85–1.93; P = 0.24) or with development of advanced neoplasia (HR, 1.38; 95% CI, 0.52–3.68; P = 0.52). There was a higher risk of colectomy in patients with PIPs (HR, 3.41; 95% CI, 1.55–7.54; P = 0.002). Conclusion In this cohort, PIPs were associated with disease extent, inflammation, and higher rates of colectomy. However, the presence of PIPs was not associated with the development of neoplasia. These findings suggest that patients with PIPs may not need an intensified surveillance strategy.

Within this large surveillance cohort of patients with colonic IBD and no additional high-risk features, having two consecutive negative colonoscopies predicted a very low risk of aCRN occurrence on follow-up. Our findings suggest that longer surveillance intervals in this selected population may be safe.
