ABSTRACT
INTRODUCTION: Biological therapies used for the treatment of inflammatory bowel disease (IBD) have shown to be effective and safe, although these results were obtained from studies involving mostly a young population, who are generally included in clinical trials. The aim of our study was to determine the efficacy and safety of the different biological treatments in the elderly population. METHODS: Multicenter study was carried out in the GETECCU group. Patients diagnosed with IBD and aged over 65 years at the time of initiating biological therapy (infliximab, adalimumab, golimumab, ustekinumab or vedolizumab) were retrospectively included. Among the patients included, clinical response was assessed after drug induction (12 weeks of treatment) and at 52 weeks. Patients' colonoscopy data in week 52 were assessment, where available. Regarding complications, development of oncological events during follow-up and infectious processes occurring during biological treatment were collected (excluding bowel infection by cytomegalovirus). RESULTS: A total of 1090 patients were included. After induction, at approximately 12-14 weeks of treatment, 419 patients (39.6%) were in clinical remission, 502 patients (47.4%) had responded without remission and 137 patients (12.9%) had no response. At 52 weeks of treatment 442 patients (57.1%) had achieved clinical remission, 249 patients had responded without remission (32.2%) and 53 patients had no response to the treatment (6.8%). Before 52 weeks, 129 patients (14.8%) had discontinued treatment due to inefficacy, this being significantly higher (p<0.0001) for Golimumab - 9 patients (37.5%) - compared to the other biological treatments analyzed. With respect to tumor development, an oncological event was observed in 74 patients (6.9%): 30 patients (8%) on infliximab, 23 (7.14%) on adalimumab, 3 (11.1%) on golimumab, 10 (6.4%) on ustekinumab, and 8 (3.8%) on vedolizumab. The incidence was significantly lower (p=0.04) for the vedolizumab group compared to other treatments. As regards infections, these occurred in 160 patients during treatment (14.9%), with no differences between the different biologicals used (p=0.61): 61 patients (19.4%) on infliximab, 39 (12.5%) on adalimumab, 5 (17.8%) on golimumab, 22 (14.1%) on ustekinumab, and 34 (16.5%) on vedolizumab. CONCLUSIONS: Biological drug therapies have response rates in elderly patients similar to those described in the general population, Golimumab was the drug that was discontinued most frequently due to inefficacy. In our experience, tumor development was more frequent in patients who used anti-TNF therapies compared to other targets, although its incidence was generally low and that this is in line with younger patients based on previous literature.
ABSTRACT
INTRODUCTION: inflammatory bowel disease (IBD) is a multifactorial pathology with an increasing incidence. There is no study that has assessed a possible relationship with very high residential radon exposure in the study area. The aim of the study was to analyze if residential radon concentration is associated with a higher incidence of IBD. MATERIAL AND METHODS: an ecological study was performed. All incident cases of inflammatory bowel disease in the area of Santiago de Compostela were included between January and December 2017. Radon levels at a municipal level were correlated with demographic factors and type of IBD. RESULTS: ninety-six patients were included, 63 (65.6 %) with ulcerative colitis, 29 (30.25) with Crohn's disease and four (4.2 %) with indeterminate colitis. The incidence rate per 100,000 inhabitants-year was 21.6 cases. There were no statistically significant differences in the type of disease developed regarding radon levels (p > 0.05). No correlation between radon levels and the cumulative incidence of inflammatory bowel disease at the municipal level was observed (Spearman's rho = 0.13, p-value 0.5). CONCLUSION: in the area of Santiago de Compostela, there is a higher incidence of IBD in comparison with previous studies using western countries as reference. However, there was no correlation with the municipal average radon concentration and incidence of IBD or any of its types in this study.

BACKGROUND: monocytes play an important role in the pathogenesis of inflammatory bowel disease but data are scarce regarding activity biomarkers, above all in patients under biologic therapies. OBJECTIVE: the aim of this study was to evaluate the value of monocyte measurements in predicting flares in inflammatory bowel disease patients under maintenance treatment with anti-TNF. METHODS: a prospective, observational cohort study was designed. Relapse was defined as a Harvey-Bradshaw score > 4 in Crohn's disease, and a partial Mayo score ≥ 2 in ulcerative colitis. Monocyte concentration was quantified at 4-month intervals for twelve months. A total of 95 consecutive patients were included. Median age was 42 years, 50.5 % were female, and 75 % had Crohn's disease. RESULTS: sixteen months after inclusion, 65 (68.4 %) patients remained in clinical remission. Mean monocyte count preceding a relapse was 563 (standard deviation: 144) compared to 405 (standard deviation: 177) in patients who remained in remission. Final monocyte count was significantly different between relapse and remission in Crohn's disease (0.82; 95 % CI: 0.71-0.90; p < 0.005). According to the multivariate analysis, only monocytes and fecal calprotectin were related to more relapses. CONCLUSION: in conclusion, in inflammatory bowel disease patients under anti-TNF therapy, repeat monocyte counts could help monitor patients, at least in Crohn's disease.

BACKGROUND: Concomitant quadruple (CQT) or bismuth-containing quadruple therapy (BQT) is recommended as first-line treatment for Helicobacter pylori infection depending on antibiotic resistance. AIM: To compare the efficacy, safety, and compliance of CQT and BQT as first-line therapy for H. pylori eradication in real clinical practice in an area of high resistance to clarithromycin. METHODS: A prospective, open, comparative cross-sectional study including dyspeptic patients >18 years with H. pylori infection and with no previous eradication treatment was performed. CQT (omeprazole 20 mg + clarithromycin 500 mg + amoxicillin 1 g + metronidazole 500 mg, all given twice daily, for 14 days) or BQT (omeprazole 20 mg twice daily + 3 capsules of Pylera® 4 times a day, for 10 days) was prescribed at the discretion of the prescribing physician. Eradication was tested by 13 C-urea breath test. Efficacy was assessed by intention-to-treat (ITT) and per-protocol (PP) analyses. RESULTS: One hundred and four consecutive patients were included (64.4% female, age 52.9 years). Fifty patients received CQT and 54 BQT. Eradication rate was similar with both therapies at the PP (CQT 97.9%, 95% CI: 93.9-100 vs BQT 96.2%, 95% CI: 90.9-100, P = 0.605) and ITT analyses (CQT 98.0%, 95% CI: 94-100 vs BQT 94.4%, 95% CI: 88.1-100, P = 0.346). The rate of adverse events was also similar with CQT (56%) and BQT (46.3%). One patient in each group discontinued the treatment due to significant adverse events. CONCLUSION: The use of CQT and BQT as first-line treatment against H. pylori is similarly effective and safe strategy in an area of high clarithromycin resistance.

BACKGROUND/OBJECTIVES: The epidemiology of exocrine pancreatic insufficiency (EPI) after acute pancreatitis (AP) is uncertain. We sought to determine the prevalence, progression, etiology and pancreatic enzyme replacement therapy (PERT) requirements for EPI during follow-up of AP by systematic review and meta-analysis. METHODS: Scopus, Medline and Embase were searched for prospective observational studies or randomized clinical trials (RCTs) of PERT reporting EPI during the first admission (between the start of oral refeeding and before discharge) or follow-up (≥ 1 month of discharge) for AP in adults. EPI was diagnosed by direct and/or indirect laboratory exocrine pancreatic function tests. RESULTS: Quantitative data were analyzed from 370 patients studied during admission (10 studies) and 1795 patients during follow-up (39 studies). The pooled prevalence of EPI during admission was 62% (95% confidence interval: 39-82%), decreasing significantly during follow-up to 35% (27-43%; risk difference: - 0.34, - 0.53 to - 0.14). There was a two-fold increase in the prevalence of EPI with severe compared with mild AP, and it was higher in patients with pancreatic necrosis and those with an alcohol etiology. The prevalence decreased during recovery, but persisted in a third of patients. There was no statistically significant difference between EPI and new-onset pre-diabetes/diabetes (risk difference: 0.8, 0.7-1.1, P = 0.33) in studies reporting both. Sensitivity analysis showed fecal elastase-1 assay detected significantly fewer patients with EPI than other tests. CONCLUSIONS: The prevalence of EPI during admission and follow-up is substantial in patients with a first attack of AP. Unanswered questions remain about the way this is managed, and further RCTs are indicated.

OBJECTIVE: The benefits of pancreatic enzyme replacement therapy (PERT) in chronic pancreatitis (CP) are inadequately defined. We have undertaken a systematic review and meta-analysis of randomised controlled trials of PERT to determine the efficacy of PERT in exocrine pancreatic insufficiency (EPI) from CP. DESIGN: Major databases were searched from 1966 to 2015 inclusive. The primary outcome was coefficient of fat absorption (CFA). Effects of PERT versus baseline and versus placebo, and of different doses, formulations and schedules were determined. RESULTS: A total of 17 studies (511 patients with CP) were included and assessed qualitatively (Jadad score). Quantitative data were synthesised from 14 studies. PERT improved CFA compared with baseline (83.7±6.0 vs 63.1±15.0, p<0.00001; I2=89%) and placebo (83.2±5.5 vs 67.4±7.0, p=0.0001; I2=86%). PERT improved coefficient of nitrogen absorption, reduced faecal fat excretion, faecal nitrogen excretion, faecal weight and abdominal pain, without significant adverse events. Follow-up studies demonstrated that PERT increased serum nutritional parameters, improved GI symptoms and quality of life without significant adverse events. High-dose or enteric-coated enzymes showed a trend to greater effectiveness than low-dose or non-coated comparisons, respectively. Subgroup, sensitive and meta-regression analyses revealed that sample size, CP diagnostic criteria, study design and enzyme dose contributed to heterogeneity; data on health inequalities were lacking. CONCLUSIONS: PERT is indicated to correct EPI and malnutrition in CP and may be improved by higher doses, enteric coating, administration during food and acid suppression. Further studies are required to determine optimal regimens, the impact of health inequalities and long-term effects on nutrition.

BACKGROUND: The rate of H. pylori resistance to different antibiotics is increasing and determines the selection of eradication therapy. The aim of this study was to determine the resistance patterns of H. pylori strains in our area. METHODS: Biopsies from gastric corpus for microbiological culture and antibiotic resistance were obtained in patients undergoing upper gastrointestinal endoscopy for dyspepsia. Selective Agar Pylori for isolation of the bacteria and Agar Mueller-Hinton supplemented with blood to test the sensitivity to antibiotics were used. Presence of H. pylori was confirmed using direct observation with phase-contrast microscopy and/or smears stained with acridine orange. In vitro bacterial susceptibility to amoxicillin, clarithromycin, rifampicin, tetracycline, metronidazole, and levofloxacin was tested using diffusion MIC test strips. Minimum inhibitory concentration values were determined based on the 6th version of the EUCAST (European Committee on Antimicrobial Susceptibility Testing) Clinical Breakpoint (2016). RESULTS: Two hundred and seventeen patients were included (58.1% female, median age 64 years, range 25-92). H. pylori was identified in 108 patients (49.8%); culture and antibiogram were completed in 77 of them (71.3% of H. pylori-positive patients). The resistance rates were as follows: levofloxacin 38.7%, rifampicin 33.3%, metronidazole 27% and clarithromycin 22.4%. No case of amoxicillin or tetracycline resistance was identified. Dual clarithromycin-metronidazole resistance was observed in 10% of strains, whereas multiple drug-resistant was observed in 14.2%. CONCLUSIONS: Resistance rate of H. pylori to antibiotics is high in the northwest of Spain. The high resistance to levofloxacin and clarithromycin advises against their wide empirical use of these antibiotics in eradication regimens.

BACKGROUND AND AIMS: Inflammatory bowel disease (IBD) is a prevalent chronic noncurable disease associated with profound metabolic changes. The discovery of novel molecular indicators for unraveling IBD etiopathogenesis and the diagnosis and prognosis of IBD is therefore pivotal. We sought to determine the distinctive metabolic signatures from the different IBD subgroups before treatment initiation. METHODS: Serum and urine samples from newly diagnosed treatment-naïve IBD patients and age and sex-matched healthy control (HC) individuals were investigated using proton nuclear magnetic resonance spectroscopy. Metabolic differences were identified based on univariate and multivariate statistical analyses. RESULTS: A total of 137 Crohn's disease patients, 202 ulcerative colitis patients, and 338 HC individuals were included. In the IBD cohort, several distinguishable metabolites were detected within each subgroup comparison. Most of the differences revealed alterations in energy and amino acid metabolism in IBD patients, with an increased demand of the body for energy mainly through the ketone bodies. As compared with HC individuals, differences in metabolites were more marked and numerous in Crohn's disease than in ulcerative colitis patients, and in serum than in urine. In addition, clustering analysis revealed 3 distinct patient profiles with notable differences among them based on the analysis of their clinical, anthropometric, and metabolomic variables. However, relevant phenotypical differences were not found among these 3 clusters. CONCLUSIONS: This study highlights the molecular alterations present within the different subgroups of newly diagnosed treatment-naïve IBD patients. The metabolomic profile of these patients may provide further understanding of pathogenic mechanisms of IBD subgroups. Serum metabotype seemed to be especially sensitive to the onset of IBD.

BACKGROUND: Both vedolizumab and ustekinumab are approved for the management of Crohn's disease [CD]. Data on which one would be the most beneficial option when anti-tumour necrosis factor [anti-TNF] agents fail are limited. AIMS: To compare the durability, effectiveness, and safety of vedolizumab and ustekinumab after anti-TNF failure or intolerance in CD. METHODS: CD patients from the ENEIDA registry who received vedolizumab or ustekinumab after anti-TNF failure or intolerance were included. Durability and effectiveness were evaluated in both the short and the long term. Effectiveness was defined according to the Harvey-Bradshaw index [HBI]. The safety profile was compared between the two treatments. The propensity score was calculated by the inverse probability weighting method to balance confounder factors. RESULTS: A total of 835 patients from 30 centres were included, 207 treated with vedolizumab and 628 with ustekinumab. Dose intensification was performed in 295 patients. Vedolizumab [vs ustekinumab] was associated with a higher risk of treatment discontinuation (hazard ratio [HR] 2.55, 95% confidence interval [CI]: 2.02-3.21), adjusted by corticosteroids at baseline [HR 1.27; 95% CI: 1.00-1.62], moderate-severe activity in HBI [HR 1.79; 95% CI: 1.20-2.48], and high levels of C-reactive protein at baseline [HR 1.06; 95% CI: 1.02-1.10]. The inverse probability weighting method confirmed these results. Clinical response, remission, and corticosteroid-free clinical remission were higher with ustekinumab than with vedolizumab. Both drugs had a low risk of adverse events with no differences between them. CONCLUSION: In CD patients who have failed anti-TNF agents, ustekinumab seems to be superior to vedolizumab in terms of durability and effectiveness in clinical practice. The safety profile is good and similar for both treatments.

BACKGROUND: Limited data are available on the outcome of inflammatory bowel disease (IBD) in patients with solid organ transplantation (SOT). We describe the natural history of pre-existing IBD and de novo IBD after SOT. METHODS: This was a retrospective, multicenter study that included patients with pre-existing IBD at the time of SOT and patients with de novo IBD after SOT. The primary outcome was IBD progression, defined by escalation of medical treatment, surgical therapy, or hospitalization due to refractory IBD. Risk factors were identified using multivariate Cox proportional hazard analysis. RESULTS: A total of 177 patients (106 pre-existing IBD and 71 de novo IBD) were included. Most patients with pre-existing IBD (92.5%) were in remission before SOT. During follow-up, 32% of patients with pre-existing IBD had disease progression, with a median time between SOT and IBD progression of 2.2 (interquartile range, 1.3-4.6) years. In the de novo cohort, 55% of patients had disease progression with a median time to flare of 1.9 (interquartile range, 0.8-3.9) years after diagnosis. In the pre-existing IBD cohort, active IBD at the time of SOT (hazard ratio, 1.80; 95% confidence interval, 1.14-2.84; Pâ =â .012) and the presence of extraintestinal manifestations (hazard ratio, 3.10; 95% confidence interval, 1.47-6.54; Pâ =â .003) were predictive factors for IBD progression. CONCLUSIONS: One-third of patients with pre-existing IBD and about half of patients with de novo IBD have disease progression after SOT. Active IBD at the time of SOT and the presence of extraintestinal manifestations were identified as risk factors for IBD progression.
ABSTRACT
Background: The usefulness of thiopurines has been poorly explored in pouchitis and other pouch disorders. Objective: To evaluate the effectiveness and safety of azathioprine as maintenance therapy in inflammatory pouch disorders. Design: This was a retrospective and multicentre study. Methods: We included patients diagnosed with inflammatory pouch disorders treated with azathioprine in monotherapy. Effectiveness was evaluated at 1 year and in the long term based on normalization of stool frequency, absence of pain, faecal urgency or fistula discharge (clinical remission), or any improvement in these symptoms (clinical response). Endoscopic response was evaluated using the Pouchitis Disease Activity Index (PDAI). Results: In all, 63 patients were included [54% males; median age, 49 (28-77) years]. The therapy was used to treat pouchitis (n = 37) or Crohn's disease of the pouch (n = 26). The rate of clinical response, remission and non-response at 12 months were 52%, 30% and 18%, respectively. After a median follow-up of 23 months (interquartile range 11-55), 19 patients (30%) were in clinical remission, and 45 (66%) stopped therapy. Endoscopic changes were evaluated in 19 cases. PDAI score decreased from 3 (range 2-4) to 1 (range 0-3). In all, 21 patients (33%) presented adverse events and 16 (25%) needed to stop therapy. Conclusion: Azathioprine may be effective in the long term for the treatment of inflammatory pouch disorders and could be included as a therapeutic option.
ABSTRACT
Background and aims: The role of occupation is uncertain in the onset of inflammatory bowel diseases. The aim of this study is to identify if there is a role of occupation in these diseases. Materials and methods: A case-control study with incident cases with inflammatory bowel diseases was designed. Cases and controls were recruited simultaneously and controls followed a sex and age frequency matching with cases. A detailed questionnaire was completed by all the participants. To analyze the results, a logistic regression was used. A subgroup analysis was performed for each inflammatory bowel disease. Results: A total of 141 patients with incident inflammatory bowel disease (80 ulcerative colitis, 55 Crohn's disease, and 6 unclassified colitis) and 114 controls were included. There were no statistically significant differences in type of work, working hours, contact with animals, or physical activity at work between inflammatory bowel disease patients and controls. After stratifying results according to type of IBD, there were no statistically significant differences either. Conclusions: There seems to be no risk for inflammatory bowel disease onset regarding the type of work, working hours, contact with animals, or sedentariness.
ABSTRACT
Management of ulcerative colitis after surgery suggested by guidelines (total proctocolectomy with ileal-pouch anal anastomosis) is a big challenge for physicians because patients who believed that their disease had been cured started experiencing very uncomfortable symptoms repeatedly. A high number of patients develop episodes of pouchitis, which is a non-specific inflammation of the pouch whose etiology is unknown. Antibiotics are the elective treatment for acute pouchitis, but regarding chronic pouchitis, this condition is very complicated to treat due to the absence of well-designed specific studies for this group of patients. Antibiotics, budesonide, and biological therapies are some of the recommended drugs for these patients, but despite their use, some need a permanent ileostomy.
ABSTRACT
Ustekinumab has shown efficacy in Crohn's Disease (CD) patients. To identify patient profiles of those who benefit the most from this treatment would help to position this drug in the therapeutic paradigm of CD and generate hypotheses for future trials. The objective of this analysis was to determine whether baseline patient characteristics are predictive of remission and the drug durability of ustekinumab, and whether its positioning with respect to prior use of biologics has a significant effect after correcting for disease severity and phenotype at baseline using interpretable machine learning. Patients' data from SUSTAIN, a retrospective multicenter single-arm cohort study, were used. Disease phenotype, baseline laboratory data, and prior treatment characteristics were documented. Clinical remission was defined as the Harvey Bradshaw Index ≤ 4 and was tracked longitudinally. Drug durability was defined as the time until a patient discontinued treatment. A total of 439 participants from 60 centers were included and a total of 20 baseline covariates considered. Less exposure to previous biologics had a positive effect on remission, even after controlling for baseline disease severity using a non-linear, additive, multivariable model. Additionally, age, body mass index, and fecal calprotectin at baseline were found to be statistically significant as independent negative risk factors for both remission and drug survival, with further risk factors identified for remission.
ABSTRACT
BACKGROUND: Large real-world-evidence studies are required to confirm the durability of response, effectiveness, and safety of ustekinumab in Crohn's disease (CD) patients in real-world clinical practice. METHODS: A retrospective, multicentre study was conducted in Spain in patients with active CD who had received ≥1 intravenous dose of ustekinumab for ≥6 months. Primary outcome was ustekinumab retention rate; secondary outcomes were to identify predictive factors for drug retention, short-term remission (week 16), loss of response and predictive factors for short-term efficacy and loss of response, and ustekinumab safety. RESULTS: A total of 463 patients were included. Mean baseline Harvey-Bradshaw Index was 8.4. A total of 447 (96.5%) patients had received prior biologic therapy, 141 (30.5%) of whom had received ≥3 agents. In addition, 35.2% received concomitant immunosuppressants, and 47.1% had ≥1 abdominal surgery. At week 16, 56% had remission, 70% had response, and 26.1% required dose escalation or intensification; of these, 24.8% did not subsequently reduce dose. After a median follow-up of 15 months, 356 (77%) patients continued treatment. The incidence rate of ustekinumab discontinuation was 18% per patient-year of follow-up. Previous intestinal surgery and concomitant steroid treatment were associated with higher risk of ustekinumab discontinuation, while a maintenance schedule every 12 weeks had a lower risk; neither concomitant immunosuppressants nor the number of previous biologics were associated with ustekinumab discontinuation risk. Fifty adverse events were reported in 39 (8.4%) patients; 4 of them were severe (2 infections, 1 malignancy, and 1 fever). CONCLUSIONS: Ustekinumab is effective and safe as short- and long-term treatment in a refractory cohort of CD patients in real-world clinical practice.
This large retrospective study demonstrated the short- and long-term effectiveness and safety of ustekinumab in patients with Crohn's disease in real-world clinical practice, including those with refractory disease.

Inflammatory bowel diseases (IBDs) are chronic disabling conditions, characterized by an unpredictable course with flare-ups and periods of remission, that frequently affect young people and require lifelong medical follow-up and treatment. For years, the main endpoints of IBD treatment had been clinical remission and response, followed by biomarker normalization and mucosal healing. In the last decades, different therapies have been proved to be effective to treat IBD and the use of patient reported outcome (PRO) have become more relevant. Therefore, health-related quality of life (HRQoL) that has been defined as the value assigned to the duration of life influenced by physical and mental health, has been suggested as an important endpoint for IBD management since multiple studies have shown that IBD impairs it, both physically and psychologically. Thus, HRQoL has been included as an outcome in numerous studies evaluating different IBD therapies, both clinical trials and real-life studies. It has been assessed by using both generic and specific disease tools, and most treatments used in clinical practice have been demonstrated to improve HRQoL. The relevance of HRQoL as an endpoint for new drugs is going to increase and its management and improvement will also improve the prognosis of IBD patients.
