Efficacy and safety of biological treatment for inflammatory bowel disease in elderly patients: Results from a GETECCU cohort.

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.

Clinical and treatment outcomes of a second subcutaneous or intravenous anti-TNF in patients with ulcerative colitis treated with two consecutive anti-TNF agents: data from the ENEIDA registry.

Background: Infliximab seems to be the most efficacious of the three available anti-TNF agents for ulcerative colitis (UC) but little is known when it is used as the second anti-TNF. Objectives: To compare the clinical and treatment outcomes of a second subcutaneous or intravenous anti-TNF in UC patients. Design: Retrospective observational study. Methods: Patients from the ENEIDA registry treated consecutively with infliximab and a subcutaneous anti-TNF (or vice versa), naïve to other biological agents, were identified and grouped according to the administration route of the first anti-TNF into IVi (intravenous initially) or SCi (subcutaneous initially). Results: Overall, 473 UC patients were included (330 IVi and 143 SCi). Clinical response at week 14 was 42.7% and 48.3% in the IVi and SCi groups (non-statistically significant), respectively. Clinical remission rates at week 52 were 32.8% and 31.4% in the IVi and SCi groups (nonsignificant differences), respectively. A propensity-matched score analysis showed a higher clinical response rate at week 14 in the SCi group and higher treatment persistence in the IVi group. Regarding long-term outcomes, dose escalation and discontinuation due to the primary failure of the first anti-TNF and more severe disease activity at the beginning of the second anti-TNF were inversely associated with clinical remission. Conclusion: The use of a second anti-TNF for UC seems to be reasonable in terms of efficacy, although it is particularly reduced in the case of the primary failure of the first anti-TNF. Whether the second anti-TNF is infliximab or subcutaneous does not seem to affect efficacy.

Ulcerative colitis induced by obinutuzumab in a patient treated for a folicular lymphoma.

An increasing use of immunomodulatory drugs has led to a corresponding increase in treatment-related pathologies such as inflammatory bowel disease. Here, we present a case of ulcerative colitis due to Obinutuzumab, an antiCD20 monoclonal approved for the treatment of Non-Hodgkin lymphomas.

Varicella zoster virus encephalitis: a potentially serious complication during treatment with vedolizumab.

Vedolizumab is a monoclonal antibody that has demonstrated efficacy and a good safety profile in patients with inflammatory bowel disease. Varicella zoster virus encephalitis is a potentially serious complication not previously described with its use, highlighting the importance of vaccination, as well as early diagnosis and treatment of infections in this type of patients.

Crohn's disease induced by ocrelizumab in a patient with multiple sclerosis.

Drug-induced inflammatory bowel disease (IBD) is a clinical entity on the rise due to the frequent use of immunomodulatory therapy. Here we report the case of Crohn's disease due to Ocrelizumab, a humanized anti-CD20 monoclonal antibody approved for the treatment of multiple sclerosis. The exact mechanism by which anti-CD20 antibodies can trigger IBD is unknown, but since IBD and multiple sclerosis are processes included within the spectrum of immunomediated diseases, we could suggest that Ocrelizumab could trigger IBD in genetically predisposed patients.

Performance of Screening Strategies for Latent Tuberculosis Infection in Patients with Inflammatory Bowel Disease: Results from the ENEIDA Registry of GETECCU.

(1) Aims: Patients receiving antitumor necrosis factor (anti-TNF) therapy are at risk of developing tuberculosis (TB), usually due to the reactivation of a latent TB infection (LTBI). LTBI screening and treatment decreases the risk of TB. This study evaluated the diagnostic performance of different LTBI screening strategies in patients with inflammatory bowel disease (IBD). (2) Methods: Patients in the Spanish ENEIDA registry with IBD screened for LTBI between January 2003 and January 2018 were included. The diagnostic yield of different strategies (dual screening with tuberculin skin test [TST] and interferon-×¥-release assay [IGRA], two-step TST, and early screening performed at least 12 months before starting biological treatment) was analyzed. (3) Results: Out of 7594 screened patients, 1445 (19%; 95% CI 18−20%) had LTBI. Immunomodulator (IMM) treatment at screening decreased the probability of detecting LTBI (20% vs. 17%, p = 0.001). Regarding screening strategies, LTBI was more frequently diagnosed by dual screening than by a single screening strategy (IGRA, OR 0.60; 95% CI 0.50−0.73, p < 0.001; TST, OR 0.76; 95% CI 0.66−0.88, p < 0.001). Two-step TST increased the diagnostic yield of a single TST by 24%. More cases of LTBI were diagnosed by early screening than by routine screening before starting anti-TNF agents (21% [95% CI 20−22%] vs. 14% [95% CI 13−16%], p < 0.001). The highest diagnostic performance for LTBI (29%) was obtained by combining early and TST/IGRA dual screening strategies in patients without IMM. (4): Conclusions: Both early screening and TST/IGRA dual screening strategies significantly increased diagnostic performance for LTBI in patients with IBD, with optimal performance achieved when they are used together in the absence of IMM.

Low applicability of the ''Six-and-twelve score" in hepatocellular carcinoma treated with Drug-Eluting Beads Transarterial Chemoembolization.

OBJECTIVE: The effectiveness of transarterial chemoembolization (TACE) in hepatocellular carcinoma (HCC) depends on the selection of suitable patients. The ''Six-and-twelve score" distinguishes three groups of ideal patients with different overall survival, based on the sum of the number and size of tumors. This may impact on clinical practice and trial design. The aim of this study was to assess the reproducibility and prognostic value of the model in western patients treated with Drug-Eluting Beads (DEB)-TACE. METHODS: Observational, retrospective, unicentric study with consecutive compensated patients treated with DEB-TACE from October 2008 to October 2017. Exclusion criteria were Child-Pugh ≥ 8 and DEB-TACE used as a bridge to liver transplantation. RESULTS: 225 HCC consecutive patients were included; BCLC-0/A n=131 (single nodules > 5, n=29) and BCLC-B n=94. The median overall survival (OS) was 27 months (95% CI 23.8-30.2). OS was different between BCLC-0/A vs BCLC-B: 30 vs 24 months (p= 0.03), Child-Pugh A5 vs A6-B7: 30 vs 27 months (p= 0.003). ''Six-and-twelve score" groups discriminated OS: group 1, n=123, 32 months (95% CI 27.5-63.5), group 2, n=101, 24 months (95% CI 19.6-28.4) and group 3, n=1, 27 months (p=0.024). When comparing the three scores, the ''Six-and-twelve score" showed the best discrimination power: C-index 0.603, Akaike's information criterion (AIC) 1.642, likelihood ratio test (LRT) 16.21. CONCLUSION: The ''Six-and-twelve score" is a prognostic tool for patients with HCC treated with DEB-TACE. However, few patients were included in the third group (score >12) and no differences were observed with BCLC, therefore its applicability is limited. .

Evaluation of cardiovascular events in patients with hepatocellular carcinoma treated with sorafenib in the clinical practice. The CARDIO-SOR study.

BACKGROUND AND AIMS: The effectiveness of systemic treatment in advanced hepatocellular carcinoma (HCC) depends on the selection of patients, management of cirrhosis complications and expertise to treat adverse events. The aims of the study are to assess the frequency and management of cardiovascular events in HCC patients treated with sorafenib (SOR) and to create a scale to predict the onset of major adverse cardiovascular events (MACE). METHOD: Observational retrospective study with consecutive HCC patients treated with SOR between 2007 and 2019 in a western centre. In order to classify cardiovascular risk pre-SOR, we designed the CARDIOSOR scale with age, hypertension, diabetes, dyslipidaemia and peripheral vascular disease. Other adverse events, dosing and outcome data were collected during a homogeneous protocolled follow-up. RESULTS: Two hundred ninety-nine patients were included (219 BCLC-C). The median overall survival was 11.1 months (IQR 5.6-20.5), and duration of treatment was 7.4 months (IQR 3.3-14.7). Seventeen patients (6%) stopped SOR due to cardiovascular event. Thirty-three patients suffered MACE (7 heart failure, 11 acute coronary syndrome, 12 cerebrovascular accident and 8 peripheral vascular ischemia); 99 had a minor cardiovascular event, mainly hypertension (n = 81). Age was the only independent factor associated to MACE (HR 1.07; 95% CI 1.03-1.12; P = .002). The CARDIOSOR scale allows to identify the group of patients with higher risk of MACE (sHR 3.4; 95% CI 1.4-6.7; P = .04). CONCLUSION: The incidence of cardiovascular events in HCC patients treated with SOR is higher than expected. Multidisciplinary approach and clinical tools like CARDIOSOR scale could be helpful to manage these patients.

Effectiveness and safety of methotrexate monotherapy in patients with Crohn's disease refractory to anti-TNF-α: results from the ENEIDA registry.

BACKGROUND: Methotrexate can be used to maintain remission in Crohn's disease patients who are intolerant to thiopurines. Data on its use as monotherapy in other scenarios are limited. AIM: To assess the effectiveness of methotrexate monotherapy in Crohn's disease patients after previous failure to anti-tumour necrosis factor (anti-TNFα) drugs. METHODS: A retrospective, observational multicentre study of data from the Spanish ENEIDA registry. Participants were patients with active Crohn's disease and previous failure to anti-TNFα started on methotrexate monotherapy. Short-term effectiveness was assessed at 12-16 weeks based on Harvey-Bradshaw index (HBI): clinical remission as HBI ≤ 3 points and clinical response as HBI drop of ≥ 3 points over baseline. Long-term effectiveness was defined as steroid-free methotrexate persistence from 12 to 16 weeks until maximum follow up. Adverse events were recorded. RESULTS: Data were compiled for 110 patients treated with methotrexate after a failed response to one (39%) or two (55.6%) anti-TNFα agents. Short-term clinical response and remission rates were 60% and 30.9% respectively. Of 74 patients who continued after week 16, long-term effectiveness was achieved in 82% and 74% at 12 and 24 months respectively. In the multivariate analysis, non-remission at short term (vs remission) was associated with long-term failure (HR 2.58, 95%CI 1.95-3.68, P = 0.028). Adverse events (evaluated in 100 patients) were recorded in 44%, and in 30.4% of these patients, they led to methotrexate discontinuation. CONCLUSIONS: The benefits observed suggest methotrexate monotherapy could be a valid option in Crohn's disease patients with previous failure to anti-TNFα.

Management and Outcomes of Bleeding Within 30 Days of Colonic Polypectomy in a Large, Real-Life, Multicenter Cohort Study.

BACKGROUND & AIMS: Management of delayed (within 30 days) postpolypectomy bleeding (DPPB) has not been standardized. Patients often undergo colonoscopies that do not provide any benefit. We aimed to identify factors associated with therapeutic intervention and active bleeding after DPPB. METHODS: We performed a retrospective study of 548 patients with bleeding within 30 days after an index polypectomy (DPPB; 71.9% underwent colonoscopy, 2.6% underwent primary angiographic embolization, and 25.5% were managed without intervention) at 6 tertiary centers in Spain, from January 2010 through September 2018. We collected demographic and medical data from patients. The primary outcomes were the need for therapeutic intervention and the presence of active bleeding during colonoscopy. RESULTS: A need for therapeutic intervention was associated independently with the use of antithrombotic agents, hemoglobin decrease greater than 2 g/dL, hemodynamic instability, and comorbidities (P < .05). The bleeding point during colonoscopy was identified in 344 patients; 74 of these patients (21.5%) had active bleeding. Active use of anticoagulants (odds ratio [OR], 2.6; 95% CI, 1.5-4.5), left-sided polyps (OR, 1.95; 95% CI, 1-3.8), prior use of electrocautery (OR, 2.6; 95% CI, 1.1-6.1), and pedunculated polyp morphology (OR, 1.8, 95% CI, 1-3.2) significantly increased the risk of encountering active bleeding. We developed a visual nomogram to estimate the risk of active bleeding. Overall, 43% of the cohort did not require any hemostatic therapy. Rebleeding (<6%) and transfusion requirements were low in those managed without intervention. CONCLUSIONS: In a study of patients with DPPB, we found that almost half do not warrant any therapeutic intervention. Colonoscopy often is overused for patients with DPPB. We identified independent risk factors for active bleeding that might be used to identify patients most likely to benefit from colonoscopy.

Diabetes is not associated with an increased risk of hepatocellular carcinoma in patients with alcoholic or hepatitis C virus cirrhosis.

BACKGROUND AND AIMS: diabetes has been reported as a risk factor for hepatocellular carcinoma (HCC) in population-based studies but there are controversial data in patients with cirrhosis. Metformin could have a protective role in HCC development. The aim of this study was to determine the influence of diabetes on the risk of developing HCC in patients with alcohol- and hepatitis C virus (HCV)-related cirrhosis. METHODS: a cohort of 982 Caucasian patients were analyzed with alcoholic or HCV cirrhosis, included from 1992 to 2014 in a HCC surveillance program and prospectively followed. The influence of diabetes on the development of HCC was analyzed by Kaplan Meier analysis and adjusted with a Cox regression for relevant co-factors. RESULTS: after a median follow-up of 49.5 (24.0-96.0) months, 156 patients (15.8 %) developed HCC. There were no differences in the cumulative incidences of HCC after 20 years between diabetic and non-diabetic patients in the global (53.5 % vs 45.4 %; p = 0.26), alcoholic (50.4 % vs 45.4 %; p = 0.21) or HCV (60 % vs 43.1 %; p = 0.57) cirrhosis series. Diabetes did not constitute a risk factor after adjusting for other potential co-factors, neither in the whole series (hazard ratio [HR]: 1.12, 95 % CI: 0.78-1.51; p = 0.26), alcoholic (HR: 1.160, 95 % CI: 0.74-1.82; p = 0.50) or HCV cirrhosis cohort (HR: 1.17, 95 % CI: 0.63-2.19; p = 0.60). These figures did not change after excluding patients treated with metformin. CONCLUSIONS: in Caucasian patients with alcoholic or HCV cirrhosis, diabetes is not a risk factor for developing HCC. This lack of an association does not seem to be a consequence of the protective effect of metformin.

Chromoendoscopy With Indigo Carmine vs Virtual Chromoendoscopy (iSCAN 1) for Neoplasia Screening in Patients With Inflammatory Bowel Disease: A Prospective Randomized Study.

INTRODUCTION: The risk of colon cancer is greater in patients with inflammatory bowel disease (IBD) than in the general population. Chromoendoscopy with dye (CE) is the currently recommended method for detecting dysplasia in screening colonoscopies in IBD patients; however, the role of virtual chromoendoscopy (VC) is not yet well defined. OBJECTIVE: The object of this study was to compare CE and VC with the iSCAN 1 system in the detection of neoplastic lesions in IBD patients. DESIGN: We conducted a prospective, single-center, randomized study in IBD patients who underwent a colonoscopy for colon cancer screening. A total of 129 patients were included and were randomized to undergo a CE (n = 67) or a VC (n = 62). The rates of detection of neoplastic lesions by the 2 endoscopic techniques were compared. RESULTS: A total of 19 neoplastic lesions (9 adenomas and 10 low-grade dysplasias [LGD]) was detected in 16 patients, 12 lesions in the CE group (17.9%), and 7 lesions in the VC group (11.3%; P = 0.2); no differences were found in the overall rate of detection of lesions (neoplastic or nonneoplastic; P = 1). The median of the total examination time and endoscope withdrawal time (minutes) was significantly lower in the VC group than in the CE group (15 vs 20 and 10 vs 14, respectively; P < 0.001). CONCLUSION: No differences occurred in the rate of detection of neoplastic lesions between CE and VC with iSCAN 1. The time spent on the technique with VC is significantly less than that with CE.

Idiopathic acute pancreatitis in patients with inflammatory bowel disease: A multicenter cohort study.

BACKGROUND: Idiopathic acute pancreatitis (IAP) in patients with inflammatory bowel disease (IBD) is not well characterized. Our purpose was to better understand this condition and its natural history. METHODS: Retrospective cohort study conducted at nine Spanish IBD referral centers. Patients with IBD and a first episode of acute pancreatitis (AP) between 1998 and 2018 were included. Patients with a previous episode of AP or a diagnosis of chronic pancreatitis were excluded. IAP and non-IAP were compared by multivariate logistic regression and survival analysis. RESULTS: We identified 185 patients with IBD (68.7% Crohn's disease) and a first episode of AP. Thirty-eight of those 185 (20.6%) fulfilled criteria for IAP. There were no severe cases of IAP. On multivariate analysis, AP before IBD diagnosis (21.1% vs. 3.4%, p = 0.04) and ulcerative colitis (52.6% vs. 23.1%, p = 0.002) were significantly more common in IAP. Further work-up was performed in 16/38 (42%) IAP patients, and a cause was identified in 6/16 (37.5%). Median time from AP to the end of follow-up was 6.3 years (3.1-10). Five-year risk of AP recurrence was significantly higher in IAP group (28% vs. 5.1%, log-rank p = 0.001), with a median time to first recurrence of 4.4 months (2.9-12.2). CONCLUSIONS: IAP represents the second cause of AP in patients with IBD. It is more frequent in ulcerative colitis, and presents a high risk of recurrence. Additional imaging work-up after a first episode of IAP in IBD patients is highly advisable, as it identifies a cause in more than one-third of cases.

Efficacy and safety of the SB Knife™ Jr. for the treatment of Zenker's diverticulum: a case series.

BACKGROUND AND AIMS: the stag-beetle knife is a new scissor-like endoscopic device that can be used for the treatment of Zenker's diverticulum, although experience is limited. The aim of this study was to evaluate the efficacy and safety of the SB Knife™ for the endoscopic treatment of Zenker's diverticulum. METHODS: a single-center prospective study of 16 patients was performed between May 2017 and April 2019. The rate of complications and symptom changes was evaluated. RESULTS: the median age was 78 years and 62.5% of the patients were male. All had dysphagia, 43.8% choking, 31.3% regurgitation and 6.3% respiratory symptoms. The median size of the diverticulum was 20 mm and the median follow-up was 281 days. There were no intra-procedure complications and only one major post-procedure complication was reported that was a microperforation. All patients had clinical improvement. Two patients had relapsing symptoms and were successfully treated with the same method. CONCLUSIONS: the SB Knife™ seems to be a safe and effective technique for the treatment of Zenker's diverticulum.

A multicentric Spanish study on the characteristics and survival of gastric adenocarcinoma under the age of 60.

INTRODUCTION: In Europe, gastric adenocarcinoma (GADC) is commonly regarded as a disease of the elderly. This study aims to assess the proportion, characteristics, and survival of patients diagnosed with GADC under the age of 60. MATERIALS AND METHODS: This is a retrospective, multicentric, and analytical study conducted at four tertiary Spanish hospitals. All patients diagnosed with GADC between 2008 and 2015 were included. Demographic, clinical, endoscopic, histologic, and survival data were retrieved. A multivariate analysis was performed to compare GADC in young (age≤60 years) and elderly patients. RESULTS: A total of 1374 patients with GADC were included. The mean age was 74 years (SD:11.1); 62.2% were males. There were 177 patients under the age of 60 (12.9%, 95% CI: 11.2-14.8%). GADC was frequently encountered as a metastatic disease in both young and elderly patients (Stage IV: 45.7% and 41%, respectively). In the multivariate analysis, alcohol abuse, ASA functional status I-II, diffuse subtype, neoadjuvant, and palliative therapy were independently associated (P<0.05) with age ≤60 years. No differences were found in 2-year survival (GADC ≤60: 39% vs. 35%, P=0.45). Curative-intent surgery, TNM stage I-II, body mass index<30kg/m2, and better functional status at diagnosis were independent predictors of survival in GADC under the age of 60. CONCLUSIONS: One out of eight cases of GADC were diagnosed under the age of 60. Metastatic disease was frequent at diagnosis and overall survival was poor regardless of age. Factors associated with localized disease correlated with improved survival in younger patients. Our results underline the need for early diagnosis strategies in our country.

Rate of missed oesophageal cancer at routine endoscopy and survival outcomes: A multicentric cohort study.

Background: Missed oesophageal cancer (MEC) at upper gastrointestinal endoscopy (UGE) is poorly documented. Objective: The objectives of this study were: (1) to assess the rate, predictors and survival of MEC; (2) to compare MEC and non-MEC tumours. Methods: This was a retrospective cohort study conducted at four tertiary centres. Oesophageal cancers (ECs) diagnosed between 2008 and 2015 were included. Patients with a premalignant condition (Barrett, achalasia), prior diagnosis of EC or oesophagogastric junction tumour of gastric origin were excluded. MEC was defined as EC detected within 36 months after negative UGE. Results: 123,395 UGEs were performed during the study period, with 502 ECs being diagnosed (0.4%). A total of 391 ECs were finally included. Overall MEC rate was 6.4% (95% confidence intervals (CI): 4.4-9.3%). The interval between negative and diagnostic UGE was less than 2 years in 84% of the cases. Multivariate analysis showed that a negative endoscopy was associated with proton pump inhibitor (PPI) therapy and less experienced endoscopists. MEC was smaller than non-MEC at diagnosis (25 versus 40 mm, p = 0.021), more often flat or depressed (p = 0.013) and less frequently diagnosed as metastatic disease (p = 0.013). Overall 2-year survival rate was similar for MEC (20%) and non-MEC (24.1%) (p = 0.95). Conclusions: MEC accounted for 6.4% of all ECs and was associated with poor survival. High-quality UGE and awareness of MEC may help to reduce its incidence.

Characteristics and consequences of missed gastric cancer: A multicentric cohort study.

BACKGROUND: Missed gastric cancer (MGC) is poorly documented in Mediterranean populations. AIMS: (1) To assess the rate, predictors and survival of MGC. (2) To compare MGC and non-MGC tumors. METHODS: This is a retrospective-cohort study conducted at four centers. MGC was defined as cancer detected within three years after negative esophagogastroduodenoscopy. Gastric adenocarcinomas diagnosed between 2008-2015 were included. Patients with no follow-up were excluded. RESULTS: During the study period 123,395 esophagogastroduodenoscopies were performed, with 1374 gastric cancers being diagnosed (1.1%). A total of 1289 gastric cancers were finally included. The overall rate of MGC was 4.7% (61/1289, 3.7-6%). A negative esophagogastroduodenoscopy in MGC patients was independently associated with PPI therapy (p < 0.001), previous Billroth II anastomosis (p = 0.002), and lack of alarm symptoms (p < 0.001). The most frequent location for MGC was the gastric body(52.4%). MGCs were smaller than non-MGCs (31 vs 41 mm, p = 0.047), more often flat or depressed (p = 0.003) and less likely to be encountered as advanced disease. Overall 2-year survival was similar between MGC (34.1%) and Non-MGC (35.3 %) (p = 0.59). CONCLUSION: MGC accounted for nearly five percent of newly-diagnosed gastric adenocarcinomas. Overall survival was poor and not different between MGC and non-MGC.

Impact of Epstein-Barr virus serological status on clinical outcomes in adult patients with inflammatory bowel disease.

BACKGROUND: Little is known about the impact of Epstein-Barr virus (EBV) infection on clinical outcomes in adults with inflammatory bowel disease (IBD). AIM: To evaluate seroprevalence, seroconversion rate and complications associated with EBV infection in an adult IBD cohort attending a tertiary care hospital in Spain between 2006 and 2016. METHODS: EBV serological status was determined. In seronegative patients, the seroconversion rate was evaluated. The complications associated with primary and latent EBV infection are described. RESULTS: One thousand four hundred and eighty-three patients over the age of 17 were included in the study (mean age at EBV serological status determination was 48.3). Overall seroprevalence of EBV was 97.4% (95% CI: 96.6%-98.2%). The seroconversion rate was 29.7% (95% CI: 16.2-45.9) after a mean of 47.5 months. There were no differences in seroconversion rates between patients 35 years or younger and patients older than 35 years. A 66-year-old man, on treatment with thiopurines, developed lymphoma and a hemophagocytic syndrome during a primary EBV infection. Overall, six patients (one with primary infection and five with prior EBV infection) developed lymphoma. In three of five patients with lymphoma and thiopurine use, EBV was associated to the development of lymphoma. CONCLUSIONS: There is a small percentage of adults with IBD at risk of primary EBV infection. The risks of seroconversion and its complications remain through adulthood. Our results suggest that, when considering the use of thiopurines in IBD, the information on EBV serological status should be taken into account at any age.
