Background: Metabolic associated fatty liver disease (MAFLD) stands as the leading cause of chronic liver disease globally. Notably, individuals with metabolic risk factors, such as diabetes and obesity, exhibit a staggering prevalence of MAFLD, with estimates reaching up to 70%. However, despite its widespread occurrence, there's a noticeable gap in understanding and awareness about MAFLD among these high-risk groups., Objectives: The main objective of this study was to assess the awareness and prevalence of MAFLD among diabetic patients who regularly receive secondary care focusing particularly on how multiethnic backgrounds and associated lifestyle preferences influence these health outcomes., Design: Cross-sectional study., Methods: Patients with type 2 diabetes (T2D) who regularly attend Lambeth Diabetes Intermediate Care Team clinics were invited to undergo MAFLD screening using FibroScan. Those who agreed to participate were provided with structured questionnaires on diet, physical activity, and MAFLD knowledge by a hepatologist. For each participant, anthropometric data, medical history, liver stiffness measurement, and controlled attenuation parameter (CAP) were documented. Steatosis was identified with a CAP value of ⩾275 dB/m, and advanced fibrosis was flagged at values of ⩾8 kPa., Results: The FibroScan data was valid in 96.4% (215), 53.5% (115/215) had steatosis and 26.2% (58/215) had liver fibrosis in this multiethnic high-risk group. Awareness of MAFLD was notably low at 30.9%. Alarmingly, 69% of patients diagnosed with liver fibrosis were unfamiliar with the condition. Additionally, understanding of MAFLD showed variation among different ethnic groups with highest levels were demonstrated in the Caucasian/White population (46%). Majority (96%) of these subjects were receiving specific lifestyle advice from healthcare professionals due to metabolic conditions and comorbidities. However, most patients preferred diets that were rich in carbohydrates (65.8%) and only 43% subjects performed moderate exercise daily highlighting lack of understanding regarding MAFLD and lifestyle management., Conclusion: There's a pressing need for increased awareness of MAFLD, especially in multiethnic high-risk groups. Additionally, the development of cost-effective strategies to stratify risk is essential to address this growing health concern., (© The Author(s), 2024.)

Nucleos(t)ide analogs are the cornerstone of treatment against hepatitis B virus; however, they have no direct effect on its transcriptional template (ie, covalently closed circular DNA) and so functional cure is rarely achieved. Over recent years, there has been a significant improvement in our understanding of the viral life cycle and its mechanisms of immune evasion. In this review article, we will explore novel therapeutic targets, discuss the latest data from clinical trials, and highlight future research priorities., (Copyright © 2023 Elsevier Inc.

Introduction: Given the hepatitis C virus (HCV) burden and despite curative treatments, more efforts focused on scaling-up testing and treatment in homeless populations are needed. This project aimed to implement education and flexible on-site HCV testing, treatment, and follow-up for a homeless population in south London and to evaluate engagement, therapy initiation, and cure rates., Methods: A mobile unit (van) for on-site HCV education, screening, treatment, and follow-up was placed on the street in a well-known homeless population areas from January 2018 to September 2021. Homeless was defined as living in temporary housing (hostel/hotel-based) or living on the street (street-based). Sociodemographic status, risk factors, comorbidities, concomitant medication, and data related with HCV treatment were recorded. Univariable and multivariable modeling were performed for treatment initiation and sustained virological response (SVR)., Results: Nine hundred forty homeless people were identified and 99.3% participated. 56.2% were street-based, 243 (26%) tested positive for HCV antibody, and 162 (17.4%) were viremic. Those with detectable HCV RNA had significantly more frequent psychiatric disorders, active substance use disorders, were on opioid agonist treatment, had advanced fibrosis, and had lower rates of previous treatment in comparison with undetectable HCV RNA. Overall treatment initiation was 70.4% and SVR was 72.8%. In the multivariable analysis, being screened in temporary housing (odds ratio [OR] 3.166; P = 0.002) and having opioid agonist treatment (OR 3.137; P = 0.004) were positively associated with treatment initiation. HCV treatment adherence (OR 26.552; P < 0.001) was the only factor associated with achieving SVR., Discussion: Promoting education and having flexible and reflex mobile on-site testing and treatment for HCV in the homeless population improve engagement with the health care system, meaning higher rates of treatment initiation and SVR. However, street-based homeless population not linked with harm reduction services are less likely to initiate HCV treatment, highlighting an urgent need for a broad health inclusion system., (Copyright © 2022 by The American College of Gastroenterology.)

Objectives: The course of progressive liver damage after achieving sustained virological response (SVR) with direct-acting antivirals (DAAs) remains undetermined. We aimed to determine risk factors associated with the development of liver-related events (LREs) after SVR, focusing on the utility of non-invasive markers. Methods: An observational, retrospective study that included patients with advanced chronic liver disease (ACLD) caused by hepatitis C virus (HCV), who achieved SVR with DAAs between 2014 and 2017. Patients were followed-up until December 2020. LREs were defined as the development of portal hypertension decompensation and the occurrence of hepatocellular carcinoma (HCC). Serological markers of fibrosis were calculated before treatment and one and two years after SVR. Results: The study included 321 patients, with a median follow-up of 48 months. LREs occurred in 13.7% of patients (10% portal hypertension decompensation and 3.7% HCC). Child-Pugh [HR 4.13 (CI 95% 1.74; 9.81)], baseline FIB-4 [HR 1.12 (CI 95% 1.03; 1.21)], FIB-4 one year post-SVR [HR 1.31 (CI 95% 1.15; 1.48)] and FIB-4 two years post-SVR [HR 1.42 (CI 95% 1.23; 1.64)] were associated with portal hypertension decompensation. Older age, genotype 3, diabetes mellitus and FIB-4 before and after SVR were associated with the development of HCC. FIB-4 cut-off values one and two years post-SVR to predict portal hypertension decompensation were 2.03 and 2.21, respectively, and to predict HCC were 2.42 and 2.70, respectively. Conclusions: HCV patients with ACLD remain at risk of developing liver complications after having achieved SVR. FIB-4 evaluation before and after SVR may help to predict this risk, selecting patients who will benefit from surveillance.

Hepatitis C virus (HCV) is prevalent in people with mental health disorders, a priority population to diagnose and cure in order to achieve HCV elimination. This integrated analysis pooled data from 20 cohorts in seven countries to evaluate the real-world effectiveness of the pangenotypic direct-acting antiviral (DAA) sofosbuvir/velpatasvir (SOF/VEL) in people with mental health disorders. HCV-infected patients diagnosed with mental health disorders who were treated with SOF/VEL for 12 weeks without ribavirin as part of routine clinical practice were included. The primary outcome was sustained virological response (SVR) in the effectiveness population (EP), defined as patients with an available SVR assessment. Secondary outcomes were reasons for not achieving SVR, characteristics of patients with non-virological failures, adherence, and time from HCV RNA diagnosis to SOF/VEL treatment initiation. A total of 1209 patients were included; 142 did not achieve an SVR for non-virological reasons ( n = 112; 83 lost to follow-up, 20 early treatment discontinuations) or unknown reasons ( n = 30). Of the 1067 patients in the EP, 97.4% achieved SVR. SVR rates in the EP were ≥95% when stratified by type of mental health disorder and other complicating baseline characteristics, including active injection drug use and antipsychotic drug use. Of 461 patients with data available in the EP, only 2% had an adherence level < 90% and 1% had an adherence level < 80%; all achieved SVR. Patients with mental health disorders can be cured of HCV using a well-tolerated, pangenotypic, protease inhibitor-free SOF/VEL regimen. This DAA allows the implementation of a simple treatment algorithm, with minimal monitoring requirements and fewer interactions with central nervous system drugs compared with protease-inhibitor DAA regimens.

Introduction: Despite the direct-acting antiviral therapy has dramatically decreased the likelihood of having liver-related complications and extrahepatic outcomes, the risk of developing hepatocellular carcinoma (HCC) is not totally eliminated after sustained virological response (SVR). We aimed to develop an easy-to-apply strategy to be adopted in clinical practice for accurately classifying the HCC risk in hepatitis C virus patients after SVR., Methods: Prospective and multicenter study enrolling hepatitis C virus patients with advanced fibrosis (transient elastography [TE] > 10 kPa) or cirrhosis by ultrasound showing SVR. They were followed up until HCC, liver transplantation, death, or until October 2020, which occurred first, with a minimum follow-up period of 6 months after SVR (follow-up: 49 [interquartile range 28-59] months)., Results: Patients with cirrhosis by ultrasound represented 58% (611/1,054) of the overall cohort. During the study, HCC occurrence was 5.3% (56/1,054). Multivariate analyses revealed that Fibrosis-4 (FIB-4) > 3.25 (hazard ratio [HR] 2.26 [1.08-4.73]; P = 0.030), TE (HR 1.02 [1.00-1.04]; P = 0.045) and cirrhosis by ultrasound (HR 3.15 [1.36-7.27]; P = 0.007) predicted HCC occurrence. Baseline HCC screening criteria (TE > 10 kPa or cirrhosis) identified patients at higher risk of HCC occurrence in presence of FIB-4 > 3.25 (8.8%; 44/498) vs FIB-4 < 3.25 (2.4%; 12/506), while those with only FIB > 3.25 had no HCC (0%; 0/50) (logRank 22.129; P = 0.0001). A combination of baseline FIB-4 > 3.25 and HCC screening criteria had an annual incidence >1.5 cases per 100 person-years, while the rest of the groups remained <1 case. Patients who maintained post-treatment FIB-4 > 3.25 and HCC screening criteria remained at the highest risk of HCC occurrence (13.7% [21/153] vs 4.9% [9/184]; logRank 7.396, P = 0.007)., Discussion: We demonstrated that a two-step strategy combining FIB-4, TE, and ultrasound could help stratify HCC incidence risk after SVR., (Copyright © 2021 by The American College of Gastroenterology.)

Introduction: several barriers remain in the hepatitis C care cascade, which need to be removed in order to eliminate chronic hepatitis C. These barriers include deficiencies in screening and confirmatory diagnosis as well as difficulties in accessing treatment., Aims: to identify factors associated with the non-referral of patients with positive hepatitis C virus (HCV) antibodies and to identify factors associated with loss of follow-up or non-attendance of these patients to specialist consultation after referral., Methods: observational and retrospective single-center-study, including all positive HCV serology tests performed between January 2013 and May 2018, in the Virgen Macarena health area (Seville, Spain) before implementing the one-step diagnosis. Non-referred patients and patients who were lost to follow-up after being referred were identified., Results: a total of 54 (77.4 %) patients diagnosed in Primary Care (PC) and 54 (22.2 %) from hospital specialists were not referred (p < 0.001). Predictors for non-referral were: stay in prison/institutionalization (p = 0.04), suffering chronic obstructive pulmonary disease (COPD) (p = 0.07), a normal AST value (p = 0.034) or test requested by Primary Care physician (PCP) (p = 0.004). Patients referred from PC were more likely to be lost to follow-up than those referred from hospital specialists (p < 0.001). Predictors of follow-up loss included: opioid replacement therapy (p = 0.034), absence of high blood pressure (p = 0.039) and test requested by PCP (p = 0.049)., Conclusions: a high percentage of patients with positive HCV serology were not referred or were lost to follow-up, mainly those belonging to high risk social groups or those with associated comorbidities. Patients with average values of transaminases or those diagnosed in PC were also less frequently referred.

We present the case of a 71-year-old male with a medical history of hypertension, dyslipidemia, and acute myocardial infarction in 2007 who was taking low-dose aspirin and bemiparin 3500 IU every 24 hours. He was admitted to the Urology Service with recurrent hematuria 14 days after radical prostatectomy, which ceased after continuous bladder irrigation.

Hepatitis C virus (HCV) one-step diagnosis improves recovery in patients with active infection. However, patients with previous anti-HCV+ may be excluded. We aimed to identify and retrieve non-referred or lost-to-follow-up HCV-infected patients. All anti-HCV+ patients seen in our hospital between 2013 and 2018 were included. In the first phase, we identified anti-HCV+ patients who were not referred to the Gastroenterology Unit (GU) or lost-to-follow-up. In the second phase, recovered patients were invited for a one-step visit for liver evaluation. A total of 1330 anti-HCV+ patients were included: 21.7% had not been referred to GU, and 23.1% were lost-to-follow-up. In the second phase, 49.6% of patients were contacted, and 92.8% attended a medical consultation: 62.7% had active infection, 92.2% were treated, and 86.5% achieved SVR (ITT). We concluded that screening microbiological data and referring unidentified patients with active HCV infection directly to specialists is an effective tool in achieving HCV microelimination., (© 2021 John Wiley & Sons A/S.

Introduction: patients with advanced chronic liver disease (CLD) may be at an increased risk of a severe course due to cirrhosis-associated immune dysfunction. The aim of this study was to determine the prevalence of CLD in COVID-19 patients and to analyze the course of the infection, compared with patients with non-liver disease., Materials and Methods: this was a retrospective single center study of all patients with a positive SARS-CoV-2 polymerase chain reaction (PCR) test from March 23rd to April 30th, 2020. Clinical and biochemical data of patients with and without CLD and COVID-19 were collected from the medical records., Result: four hundred and forty-seven patients with a SARS-CoV-2 positive PCR were included, 6.3 % had CLD; 69.7 % of patients with CLD were male, with a median age of 65.5 years and active alcohol consumption and smoking; 75 % had non-advanced liver fibrosis and most had non-alcoholic fatty liver disease (NAFLD). The hospital admission rate (92.9 % vs 47.7 %, p < 0.001), concomitant comorbidities (diabetes 38.5 vs 16.5 %, p = 0.011; obesity 30.8 vs 8.5 %, p = 0.033; cancer 23.1 vs 5 %, p = 0.027; and chronic obstructive pulmonary disease (COPD) 19.2 vs 9 %, p = 0.009) and concomitant antibiotics treatment (19.3 vs 5 %, p = 0.018) were higher in patients with CLD than in those without CLD. In-patient hospital mortality rates were similar in both groups (30.8 vs 19.6 %, p = 0.289). The presence of CLD was not associated with mortality (OR = 1.06; 95 % CI = 0.35-3.18; p = 0.924). However, patients with CLD and COVID-19 who were male, obese or under concomitant antibiotic treatment had the highest risk of mortality according to the univariate analysis., Conclusion: patients with CLD had a higher risk of hospital admission, with worse outcomes during the COVID-19 infection associated to other concomitant comorbidities and a suspicion of bacterial co-infection.

Introduction: endoscopy plays an essential role in the management of patients with ulcerative colitis (UC), as it allows us to visualize and assess the severity of the disease. Different scores have been devised to standardize the findings because such assessments are not always objective., Aims: the aim of this study was to assess the interobserver variability between the Index of Mayo Endoscopy (IME) and the Ulcerative Colitis Endoscopy Index of Severity (UCEIS), analyzing the severity of the endoscopic lesions in patients with UC. The secondary aim was to analyze if the cathartic preparation affected the degree of concordance amongst the endoscopists., Material and Methods: this was a single-cohort observational, comparative study in which a colonoscopy was performed in patients with UC, as the normal clinical practice. The results were classified according to the IME and the UCEIS by three endoscopic specialists. In order to assess the degree of interobserver correlation, the Kappa index for IME was used and the intraclass correlation coefficient was used for UCEIS., Results: sixty-seven patients were included in the study. The average age was 51 (SD ± 16.7) and the average Mayo Clinic index was 3.07 (SD ± 2.54). The weighted Kappa index between endoscopists A and B for the IME was 0.8, 0.52 between A and C and 0.49 between B and C. The intraclass correlation coefficient for UCEIS was 0.922 between the three endoscopists (95 % CI: 0.832-0.959). A better interobserver correlation was found when the cathartic preparation was ≥ 8 based on the Boston Scale., Conclusions: there was a higher correlation between the different endoscopists for the UCEIS than for the IME. Thus, this should be considered to be the best index to use in the clinical practice. A good cleansing preparation is important to improve the interobserver correlation.

Neuroendocrine tumors rarely occur in the esophagus because the neuroendocrine system is not well developed in the esophagus. The case of a neuroendocrine esophageal tumor developed in a patient with Barret's esophagus is presented. It was successfully trated by endoscopy.

Introduction: between 30 % and 40 % of patients treated with infliximab lose response during maintenance. Therapeutic drug monitoring could be used to optimize management in these situations. However, infliximab serum levels are not well defined. The aim of this study was to determine the cut-off range of infliximab serum levels in Crohn's disease patients in remission in the clinical practice., Methods: an observational retrospective study was performed from 2016 to 2017. Patients were included with established Crohn's disease, who had been on a maintenance dose schedule of infliximab. Infliximab levels and antibodies to infliximab were measured at least twice in all patients, after induction and after six months of treatment. Clinical remission was defined as ≤ 4 using the Harvey-Bradshaw index. Cluster analysis was used to analyze the results., Results: one hundred and five Crohn's disease patients were included in the study; 57.1 % were male with a mean age of 39 years (SD ± 12.9). The median (range) time of the disease was eleven years (7-15) and the median (range) time of follow-up was 32 months (22-38). Patients who achieved remission had infliximab serum levels between 4.26-8.26 ug/ml versus 0.06-1.43 ug/ml in patients who did not achieve remission after induction. Infliximab serum levels were 2.84-7.75 ug/ml and 0.05-2.69 ug/ml in patients who achieved remission versus those who did not achieve remission after six months of treatment. Overall, 4.26-8.26 ug/ml was found to be the best cut-off range for remission., Conclusions: in our clinical practice, serum levels of infliximab in Crohn's disease patients should be higher than 4 ug/ml to achieve clinical remission.

Background & Aims: It is not clear whether closure of mucosal defects with clips after colonic endoscopic mucosal resection (EMR) prevents delayed bleeding, although it seems to have no protective effects when risk is low. We performed a randomized trial to evaluate the efficacy of complete clip closure of large (≥2 cm) nonpedunculated colorectal lesions after EMR in patients with an estimated average or high risk of delayed bleeding., Methods: We performed a single-blind trial at 11 hospitals in Spain from May 2016 through June 2018, including 235 consecutive patients who underwent EMR for large nonpedunculated colorectal lesions with an average or high risk of delayed bleeding (based on Spanish Endoscopy Society Endoscopic Resection Group score). Participants were randomly assigned to groups that received closure of the scar with 11-mm through-the-scope clips (treated, n = 119) or no clip (control, n = 116). The primary outcome was proportion of patients in each group with delayed bleeding, defined as evident hematochezia that required medical intervention within 15 days after colonoscopy., Results: In the clip group, complete closure was achieved in 68 (57%) cases, with partial closure in 33 (28%) cases and failure to close in 18 (15%) cases. Delayed bleeding occurred in 14 (12.1%) patients in the control group and in 6 (5%) patients in the clip group (absolute risk difference, reduction of 7% in the clip group; 95% confidence interval, -14.7% to 0.3%). After completion of the clip closure, there was only 1 (1.5%) case of delayed bleeding (absolute risk difference, reduction of 10.6%; 95% confidence interval, -4.3% to 17.9%)., Conclusions: In a randomized trial of patients with large nonpedunculated colorectal lesions undergoing EMR, we found that clip closure of mucosal defects in patients with a risk of bleeding can be a challenge, but also reduces delayed bleeding. Prevention of delayed bleeding required complete clip closure. ClinicalTrials.gov ID: NCT02765022., (Copyright © 2019 AGA Institute. Published by Elsevier Inc. All rights reserved.)

Background and Aims: To evaluate the clinical outcomes in patients with IBD after switching from Remicade® to CT-P13 in comparison with patients who maintain Remicade®., Methods: Patients under Remicade® who were in clinical remission with standard dosage at study entry were included. The 'switch cohort' [SC] comprised patients who made the switch from Remicade® to CT-P13, and the 'non-switch' cohort [NC] patients remained under Remicade®., Results: A total of 476 patients were included: 199 [42%] in the SC and 277 [58%] in the NC. The median follow-up was 18 months in the SC and 23 months in the NC [p < 0.01]. Twenty-four out of 277 patients relapsed in the NC; the incidence of relapse was 5% per patient-year. The cumulative incidence of relapse was 2% at 6 months and 10% at 24 months in this group. Thirty-eight out of 199 patients relapsed in the SC; the incidence rate of relapse was 14% per patient-year. The cumulative incidence of relapse was 5% at 6 months and 28% at 24 months. In the multivariate analysis, the switch to CT-P13 was associated with a higher risk of relapse (HR = 3.5, 95% confidence interval [CI] = 2-6). Thirteen percent of patients had adverse events in the NC, compared with 6% in the SC [p < 0.05]., Conclusions: Switching from Remicade® to CT-P13 might be associated with a higher risk of clinical relapse, although this fact was not supported in our study by an increase in objective markers of inflammation. The nocebo effect might have influenced this result. Switching from Remicade® to CT-P13 was safe., (Copyright © 2019 European Crohn’s and Colitis Organisation (ECCO).

Background: Several studies have reported positive efficacy outcomes for patients with inflammatory bowel disease treated with CT-P13, an infliximab biosimilar. Data from follow-up periods longer than 1 year are still scarce. Here, we assessed the long-term efficacy data, loss of response and safety after switching from infliximab to CT-P13 in patients with inflammatory bowel disease., Methods: This was a prospective single-center observational study involving patients with moderate-to-severe Crohn's disease and ulcerative colitis switched from infliximab to CT-P13 treatment and reviewed up to 24 months. Efficacy and loss of response were measured using the Harvey-Bradshaw (HB) index and partial Mayo score for patients with Crohn's disease and ulcerative colitis respectively. C-reactive protein, infliximab drug levels, adverse events and antidrug antibodies were also monitored throughout the study., Results: A total of 64 patients with Crohn's disease and 36 patients with ulcerative colitis were included. Most of them (72%) remained on CT-P13. Overall, 28% of patients discontinued the therapy due to loss of response, adverse events or long-lasting clinical remission. Remission at 18 and 24 months occurred in 69.9% and 68.5% of patients, respectively. Dose increase was performed in 22% of patients, with remission being reached in 60% of them. HB index, partial Mayo score, C-reactive protein and infliximab drug levels did not show significant changes. Serious adverse events were reported in 14% of patients. Overall, two patients developed low levels of antidrug antibodies., Conclusions: Most of the patients switching from original infliximab were maintained on CT-P13 at 2 years of follow up with a good profile of efficacy and safety., Competing Interests: Conflict of interest statement: M.F.

Background: Infliximab original has changed the natural history of inflammatory bowel diseases (IBD) over the past two decades. However, the recent expiration of its patent has allowed the entry of the first Infliximab biosimilar into the European and Spanish markets. Currently switching drugs data in IBD are limited., Aim: To compare the efficacy of infliximab biosimilar, CT-P13, against infliximab original, analyzing the loss of response of both at the 12 mo follow-up in patients with IBD., Methods: An observational study of two cohorts has been conducted. One retrospective cohort that included patients with IBD treated with Infliximab original, and a prospective cohort of patients who were switching from infliximab original to infliximab biosimilar (CT-P13). We had analyzed the overall efficacy and loss of efficacy in patients in remission at the end of one year after treatment with the original drug compared to the results of the year of treatment with the biosimilar., Results: 98 patients (CD 67, CU 31) were included in both cohorts. The overall efficacy for infliximab original per year of treatment was 71% vs 68.2% for infliximab biosimilar ( P = 0.80). The loss of overall efficacy at 12 mo for infliximab original was 6.6% vs 14.5% for infliximab biosimilar ( P = 0.806). The loss of efficacy in patients who were in basal remission was 16.3% for infliximab original vs 27.1% for infliximab biosimilar. Adverse events were 9.2% for infliximab original vs 11.2% for infliximab biosimilar., Conclusion: The overall efficacy and loss of treatment response with infliximab biosimilar (CT-P13) is similar to that observed with infliximab original in patients who were switching at the 12 mo follow-up. There is no difference in the rate of adverse events., Competing Interests: Conflict-of-interest statement: Guerra Veloz MF, Castro Laria L, Maldonado Pérez B, Perea Amarillo R and Argüelles-Arias F have received financial support to attend scientific meetings from Kern Pharma. Benítez Roldán A, Merino Bohórquez V, Calleja MA, Caunedo Álvarez Á, and Vilches Arenas Á do not have conflict of interest.

Background and Aims: infliximab has changed the natural history of inflammatory bowel disease (IBD). The advent of biosimilar treatments such as CT-P13 will hopefully improve the availability of biological therapies. Data with regard to drug switching are currently limited. The objective of the study was to assess the effectiveness and safety of switching from the reference product (RP), infliximab, to CT-P13 in patients with IBD., Methods: this was a multicenter prospective observational study in patients with Crohn's disease (CD) and ulcerative colitis (UC). All patients had switched from infliximab RP (Remicade®) to CT-P13 treatment and were followed up for 12 months. The efficacy endpoint was the change in clinical remission assessed at 0 and 12 months, according to the Harvey-Bradshaw score and partial Mayo score for patients with CD and UC, respectively. Adverse events were monitored and recorded throughout the study., Results: a total of 167 patients (116 CD/51 UC) were included; 88.8% (103/116) of patients with CD were in remission at the time of the drug switch and 69.7% were in remission at 12 months. The Harvey-Bradshaw (HB) score significantly changed at 12 months (p = 0.001); 84.3% (43/51) of patients with UC were in remission at the time of the drug switch and 76.7% were in remission at 12 months. No significant changes in the median partial Mayo score (p = 0.87) were observed at 12 months. Serious adverse events related to medication were reported in 12/167 (7.2%) cases., Conclusion: switching from infliximab RP to CT-P13 is safe and effective at 12 months. The loss of efficacy at 12 months was 15.7%.

Endoscopic ultrasound (EUS)-guided drainage of pancreatic collections has replaced surgery as the first line of treatment due its accuracy and safety profile. A higher success rate and fewer adverse events has been observed using fully covered metal stent for the drainage. However, complications of EUS-guided drainage can appear. We present a case of late migration of the stent.

We present a case of ileocecal endometriosis as a cause of infrequent ileocolic intussusception in an adult patient. It is reviewed as published by the authors Sanchez Cifuentes, A et al. 2016, emphasizing the rarity of the location of endometriosis, and its association as a cause of intussusception.

Background: Biological agents, such as infliximab, have transformed the outcomes of patients with immune-mediated inflammatory diseases. The advent of biosimilar treatment options such as CT-P13 promises to improve the availability of biological therapy, yet real-world switching data are currently limited. Here, we assess the effectiveness and safety of switching to CT-P13 from infliximab reference product (RP) in patients with inflammatory bowel disease., Materials and Methods: This was a prospective single-center observational study in patients with moderate to severe Crohn's disease (CD) and ulcerative colitis (UC). All patients were switched from infliximab RP (Remicade) to CT-P13 treatment and followed up for up to 12 months. The efficacy endpoint was the change in clinical response assessed at 3-monthly intervals, according to the Harvey-Bradshaw score and partial Mayo score for patients with CD and UC, respectively. C-reactive protein (CRP) was also measured. Adverse events were monitored and recorded throughout the study., Results: A total of 98 patients with inflammatory bowel disease (67 CD/31 UC) were included. A total of 83.6% (56/67) of patients with CD were in remission at the time of the switch and 62.7% were in remission at 12 months. The Harvey-Bradshaw score showed a significant change at 12 months (P=0.007) but no significant change was observed in median CRP at this timepoint (P=0.364). A total of 80.6% (25/31) of patients with UC were in remission at the time of the switch and 65.3% (18/28) were in remission at 12 months. No significant changes in the median partial Mayo score (P=0.058) or CRP (P=0.329) were observed at 12 months. Serious adverse events related to medication were reported in 11 (11.2%) patients., Conclusion: Switching from infliximab RP to CT-P13 is efficacious and well tolerated in patients with CD or UC for up to 12 months.

Background: The incidence of inflammatory bowel disease is increasing in Europe and in Spain. However, there is no recent data from Southern Spain., Objectives: To determine the evolution of the hospital incidence of inflammatory bowel disease in Southern Spain., Material and Methods: A retrospective study was performed in two hospitals in Southern Spain. Data was collected from inflammatory bowel disease patients, divided into two periods (1995-2000 and 2001-2014) and compared. The reference population from both areas was 1,011,555 inhabitants., Results: A total of 430 patients were registered during the first period (1995-2000); 50% (215) had Crohn's disease that resulted in a cumulative incidence rate of 7.08 cases/100,000 inhabitants per year. The overall inflammatory bowel disease incidence was 3.54 cases/100,000 inhabitants per year. During the second period (2001-2014), 2,089 patients were collected; 51.7% had ulcerative colitis (1,081). The rate of cumulative incidence of inflammatory bowel disease was 14.7 cases/100,000 inhabitants per year (7.6 cases of ulcerative colitis/100,000 inhabitants/year and 7.1 cases of Crohn´s disease/100,000 inhabitants/year)., Conclusions: The incidence of inflammatory bowel disease in Southern Spain has doubled in the last decade and is similar to that of the rest of the country and Europe.

Background: CT-P13 is a biosimilar of Remicade ® , an agent approved in some countries for use in inflammatory bowel disease (IBD). Controlled clinical trials have demonstrated the efficacy and safety of CT-P13 in rheumatic diseases, but not in IBD., Aims: To assess the effectiveness and safety of CT-P13 in IBD patients in real clinical practice., Methods: This is a prospective observational study in patients with moderate to severe Crohn's disease or ulcerative colitis treated with CT-P13. The study was performed in one single center. Patients included were naive or switched to anti-TNF treatment from the reference infliximab (Remicade ® ) to CT-P13. Efficacy and safety were assessed in naive and switched patients who were in remission at the time of the switch at months 3 and 6 of therapy., Results: 87.5 and 83.9% of switched CD patients who were in remission at the time of the switch continued in remission, and 66.7 and 50% of naive CD patients reached remission, at months 3 and 6. In UC switched cases, 92 and 91.3% of patients in remission at the time of the switch continued in remission, at 3 and 6 months. In naive UC patients, the remission rates were 44.4 and 66.7%, at months 3 and 6. Adverse events occurred in 7.5% of patients during 6 months of study., Conclusions: CT-P13 was efficacious and well tolerated in patients with CD or UC.
