Effectiveness and safety of azathioprine for inflammatory pouch disorders: results from the RESERVO study of GETECCU.

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.

Indications and hemoglobin thresholds for red blood cell transfusion and iron replacement in adults with gastrointestinal bleeding: An algorithm proposed by gastroenterologists and patient blood management experts.

Gastrointestinal (GI) bleeding is associated with considerable morbidity and mortality. Red blood cell (RBC) transfusion has long been the cornerstone of treatment for anemia due to GI bleeding. However, blood is not devoid of potential adverse effects, and it is also a precious resource, with limited supplies in blood banks. Nowadays, all patients should benefit from a patient blood management (PBM) program that aims to minimize blood loss, optimize hematopoiesis (mainly by using iron replacement therapy), maximize tolerance of anemia, and avoid unnecessary transfusions. Integration of PBM into healthcare management reduces patient mortality and morbidity and supports a restrictive RBC transfusion approach by reducing transfusion rates. The European Commission has outlined strategies to support hospitals with the implementation of PBM, but it is vital that these initiatives are translated into clinical practice. To help optimize management of anemia and iron deficiency in adults with acute or chronic GI bleeding, we developed a protocol under the auspices of the Spanish Association of Gastroenterology, in collaboration with healthcare professionals from 16 hospitals across Spain, including expert advice from different specialties involved in PBM strategies, such as internal medicine physicians, intensive care specialists, and hematologists. Recommendations include how to identify patients who have anemia (or iron deficiency) requiring oral/intravenous iron replacement therapy and/or RBC transfusion (using a restrictive approach to transfusion), and transfusing RBC units 1 unit at a time, with assessment of patients after each given unit (i.e., "don't give two without review"). The advantages and limitations of oral versus intravenous iron and guidance on the safe and effective use of intravenous iron are also described. Implementation of a PBM strategy and clinical decision-making support, including early treatment of anemia with iron supplementation in patients with GI bleeding, may improve patient outcomes and lower hospital costs.

[ESPEN guideline: Clinical nutrition in inflammatory bowel disease]. / Guía ESPEN: Nutrición clínica en la enfermedad inflamatoria intestinal.

Introduction: Introduction: the ESPEN guideline offers a multidisciplinary focus on clinical nutrition in inflammatory bowel disease (IBD). Methodology: the guideline is based on a extensive systematic review of the literature, but relies on expert opinion when objective data are lacking or inconclusive. The conclusions and 64 recommendations have been subject to full peer review and a Delphi process, in which uniformly positive responses (agree or strongly agree) were required. Results: IBD is increasingly common and potential dietary factors in its etiology are briefly reviewed. Malnutrition is highly prevalent in IBD - especially in Crohn's disease. Increased energy and protein requirements are observed in some patients. The management of malnutrition in IBD is considered within the general context of support for malnourished patients. Treatment of iron deficiency (parenterally, if necessary) is strongly recommended. Routine provision of a special diet in IBD is not, however, supported. Parenteral nutrition is indicated only when enteral nutrition has failed or is impossible. The recommended perioperative management of patients with IBD undergoing surgery accords with general ESPEN guidance for patients having abdominal surgery. Probiotics may be helpful in UC but not in Crohn's disease. Primary therapy using nutrition to treat IBD is not supported in ulcerative colitis but is moderately well supported in Crohn's disease, especially in children, where the adverse consequences of steroid therapy are proportionally greater. However, exclusion diets are generally not recommended and there is little evidence to support any particular formula feed when nutritional regimens are constructed. Conclusions: available objective data to guide nutritional support and primary nutritional therapy in IBD are presented as 64 recommendations, of which 9 are very strong recommendations (grade A), 22 are strong recommendations (grade B), and 12 are based only on sparse evidence (grade 0); 21 recommendations are good practice points (GPP).

Introducción: Introducción: la guía ESPEN ofrece un enfoque multidisciplinar de la nutrición clínica en la enfermedad inflamatoria intestinal (EII). Metodología: la guía se basa en una extensa revisión sistemática de la literatura y en la opinión de expertos cuando faltan datos objetivos o estos no son concluyentes. Las conclusiones y las 64 recomendaciones han sido objeto de una revisión completa por pares y de un proceso Delphi en el que se requerían respuestas fuertemente positivas (de acuerdo o totalmente de acuerdo). Resultados: la EII es cada vez más común y se revisan brevemente los posibles factores dietéticos en su etiología. La desnutrición es muy prevalente en la EII, especialmente en la enfermedad de Crohn. En algunos pacientes se observan mayores requerimientos de energía y proteínas. El manejo de la desnutrición en la EII se considera dentro del contexto general de apoyo a los pacientes desnutridos. Se recomienda fuertemente el tratamiento de la deficiencia de hierro (por vía parenteral, si es necesario). Sin embargo, no se aconseja la prescripción de rutina de una dieta especial en la EII. La nutrición parenteral está indicada solo cuando la nutrición enteral ha fallado o es imposible. El manejo perioperatorio recomendado de los pacientes con EII sometidos a cirugía se hace de acuerdo con la guía general de la ESPEN para pacientes sometidos a cirugía abdominal. Los probióticos pueden ser útiles en la CU pero no en la enfermedad de Crohn. El tratamiento primario con nutrición para tratar la EII no está respaldado en la colitis ulcerosa, aunque está moderadamente bien soportado en la enfermedad de Crohn, especialmente en los niños, donde las consecuencias adversas de la terapia con esteroides son proporcionalmente mayores. Sin embargo, las dietas de exclusión generalmente no se recomiendan y hay poca evidencia que respalde cualquier fórmula de nutrición en particular cuando se realizan regímenes nutricionales. Conclusiones: los datos objetivos disponibles para guiar el apoyo nutricional y la terapia nutricional primaria en la EII se presentan como 64 recomendaciones, de las cuales 9 son recomendaciones muy fuertes (grado A), 22 son recomendaciones fuertes (grado B) y 12 se basan solo en evidencia escasa (grado 0); 21 recomendaciones son recomendaciones de buenas prácticas (GPP).

Validation of screening criteria for spondyloarthritis in patients with inflammatory bowel disease in routine clinical practice.

BACKGROUND: Spondyloarthritis (SpA) is one of the most common extraintestinal manifestations of inflammatory bowel disease (IBD). Diagnostic delay must be avoided. AIMS: We assessed the validity of SpA screening criteria (any of the following characteristics: chronic low back pain with onset before 45 years of age; inflammatory lower back pain or alternating buttock pain; arthritis; heel enthesitis; dacylitis; HLA-B27 positivity; sacroiliitis on imaging). METHODS: This was a multicenter cross-sectional observational study in IBD patients aged ≥18 years. After evaluating the SpA screening criteria, the gastroenterologists referred the participants to the rheumatologists, who determined whether the patient fulfilled the screening criteria and carried out the necessary tests for SpA diagnosis. RESULTS: 35 (11.7%) out of 300 patients were diagnosed with SpA. The combination with the best balance between sensitivity and specificity (91.4% and 72.1%, respectively, when applied by the rheumatologists; 80% and 78.9%, when applied by the gastroenterologists) for SpA screening, was fulfillment of any of the following: chronic low back pain with onset before age 45 years, inflammatory low back pain or alternating buttock pain, arthritis, or dactylitis. CONCLUSION: This is one of the first studies to validate SpA screening criteria in IBD patients in routine clinical practice.

Influence of Compliance to Diet and Self-Efficacy Expectation on Quality of Life in Patients with Celiac Disease in Spain.

The purpose of this study is to understand the health-related quality of life (HRQoL) in patients with celiac disease (CD) and analyze its main determinants. A transversal descriptive study of 738 patients with celiac disease was carried out. A series of questionnaires were answered related to their HRQoL, adherence to a gluten-free diet (GFD), and self-efficacy beliefs among other relevant variables. Regression analyses were carried out in order to explore the predictive variables in adherence to the GFD and HRQoL. A total of 61.2% showed a good HRQoL, and the main predictors of HRQoL were specific self-efficacy, adherence to the diet, risk perception, time since diagnosis, and age. While 68.7% of participants showed good or excellent adherence to the GFD, and the main predictors of adherence were specific self-efficacy, perceived adoption of recommended behaviors, HRQoL and gender. The HRQoL of patients with CD, and adherence to the GFD in Spain, are good. It is the self-efficacy expectation, measured specifically and not generally, which is the best predictor of both adherence and HRQoL. It is necessary to develop programs to improve the HRQoL of patients with CD that focus on improving specific self-efficacy.

Prospective, study comparing the accuracy of two different stool antigen tests (Premier Platinum HpSA and novel ImmunoCard STAT rapid test) for the diagnosis of Helicobacter pylori infection / Estudio prospectivo y comparativo entre la exactitud de 2 pruebas de antígenos en heces (Premier Platinum HpSA® y el nuevo test rápido ImmunoCard® STAT) para el diagnóstico de la infección por Helicobacter pylori

BACKGROUND: At present only monoclonal EIA (enzyme-immunoassay) stool antigen-tests have obtained optimal accuracy in the diagnosis of Helicobacter pylori. Our aim was to evaluate the accuracy of two stool antigen-tests, the validated Premier Platinum HpSA PLUS (EIA test) and the newly available ImmunoCard STAT! HpSA HD (rapid test) for the initial diagnosis and the confirmation of eradication of H. pylori infection. PATIENTS AND METHODS: Patients with indication of H. pylori diagnosis, or confirmation after treatment were included. Data were coded to protect personal data and ensure blindness between tests. Accuracy was considered as coincident diagnosis with the gold standard (13C-urea breath test, UBT). The EIA was used as a bench standard. All stool tests were performed in duplicate. RESULTS: 264 patients completed the protocol (100 naïve, 164 post-eradication). Average age was 52 years, 61% women, 11% ulcer. Positive diagnoses by UBT were 41% for naïve and 17% for post-eradication. Overall ImmunoCard and EIA accuracies were respectively 91% (95%C. I. =88-94%) and 89% (86-93%), sensitivities 72% (67-78%) and 72% (67-78%), and specificities 98% (96-100%), and 95% (92-97%). Concordance between ImmunoCard and EIA was 95% (93-98%). DISCUSSION: Our results indicate that the newly available ImmunoCard rapid stool antigen-test achieves 90% accuracy, with high specificity but suboptimal sensitivity. The ImmunoCard attained equivalent accuracies as the EIA bench standard, with 95% concordance

ANTECEDENTES: En la actualidad, únicamente los métodos de detección de antígenos en heces monoclonales basados en enzimoinmunoanálisis (ELISA) han obtenido una adecuada precisión para el diagnóstico de la infección por Helicobacter pylori. Nuestro objetivo fue evaluar la exactitud (sensibilidad y especificidad) de 2 métodos de antígenos en las heces, el previamente validado Premier Platinum HpSA® PLUS (ELISA) y el nuevo ImmunoCard® STAT! HpSA® HD (test rápido), para el diagnóstico inicial y la confirmación de la erradicación de la infección por H. pylori. PACIENTES Y MÉTODOS: Se incluyeron pacientes en los que estaba indicado el diagnóstico inicial de la infección por H. pylori o su confirmación tras el tratamiento. Los datos fueron codificados y los evaluadores de ambos test fueron ciegos para los resultados de las pruebas diagnósticas. El resultado principal fue la coincidencia con el resultado del patrón oro (prueba del aliento con 13C-urea). Los test en heces se realizaron por duplicado. RESULTADOS: Doscientos sesenta y cuatro pacientes completaron el protocolo (100 naïve, 164 posterradicación). La edad media fue de 52 años, el 61% fueron mujeres y el 11% tenían úlcera péptica. La prueba del aliento fue positiva en el 41% de los pacientes naïve y en el 17% posterradicación. La exactitud global del método rápido y del ELISA fue, respectivamente, 91% (IC 95%: 88-94%) y 89% (86-93%), la sensibilidad 72% (67-78%) y 72% (67-78%), y la especificidad 98% (96-100%) y 95% (92-97%). La concordancia entre el método ImmunoCard® y ELISA fue del 95% (93-98%). DISCUSIÓN: El nuevo método rápido de antígenos en heces (ImmunoCard® STAT! HpSA® HD) tiene una exactitud diagnóstica del 90%, con una elevada especificidad, pero una sensibilidad insuficiente. El método ImmunoCard® tiene una exactitud equivalente al método ELISA estándar, con una concordancia del 95%

Open questions and misconceptions in the diagnosis and management of anemia in patients with gastrointestinal bleeding. / Preguntas y errores en el diagnóstico y manejo de la anemia en pacientes con hemorragia digestiva.

Despite high prevalence of iron deficiency anemia (IDA) in patients with acute or chronic gastrointestinal bleeding (GIB), IDA and iron deficiency (ID) are frequently untreated. Reasons may be misconceptions about the impact and diagnosis of IDA and the efficacy of new treatments. Addressing these misconceptions, this article summarizes current evidence for better understanding and management of GIB-associated IDA. Despite only few controlled studies evaluated the efficacy of iron treatment in patients with GIB, there is consistent evidence suggesting that: (a) IDA should be diligently investigated, (b) effective treatment of ID/IDA improves outcomes such as health-related quality of life and can avoid severe cardiovascular consequences, and (c) intravenous iron should be considered as well-tolerated treatment in this setting. Overall, the misconceptions and practices outlined in this article should be replaced with strategies that are more in line with current guidelines and best practice in GIB and other underlying conditions of ID/IDA.

Accuracy of the Ultra-Rapid Urease Test for diagnosis of Helicobacter pylori infection / Exactitud del test Ultra-Rapido de la Ureasa para el Diagnóstico de la infección por Helicobacter pylori

Background: Rapid Urease Test (RUT) is a simple, cheap and relatively fast method for diagnosing Helicobacter pylori infection. It is therefore the preferred method used for patients undergoing gastroscopy. Most kits require 24h to give results. The new Ultra-Rapid Urease Test (URUT) kit by Biohit(R) requires less than 1h. Objective: To determine URUT's diagnostic accuracy. Method: Prospective, blind, multi-centre study involving dyspeptic patients. One corpus biopsy and three antral biopsies were obtained during gastroscopy for standard histological analysis, RUT and URUT. The URUT result was checked after 1min, 5min, 30min and 60min and the RUT was checked over the course of 24h. Histology was used as the gold standard test. Results: 144 patients were included, 68% female, with a mean age of 49 years old; 50% were H. pyloripositive. RUT and URUT diagnoses were correct in 85.9% and 90% of the cases, respectively. The mean waiting time for a positive RUT result was 6h. The sensitivity, specificity, and positive and negative predictive values for RUT were, respectively, 82%, 90%, 89% and 84%. The URUT's results were similar (85%, 94%, 94% and 87%). These figures improved when patients taking PPIs were excluded (RUT: 86%, 91%, 93% and 83%; URUT: 91%, 94%, 96% and 89%). No statistically significant differences were found when comparing RUT and URUT distributions of correct diagnoses (McNemar's Test, p=0.3) but there was a tendency towards better results with the URUT. Conclusion: The URUT is equivalent to (or slightly better than) the traditional RUT in diagnosing H. pyloriinfection, and provides results in less than an hour (AU)

Introducción: El test de la ureasa (TRU) es un método simple, barato y relativamente rápido para el diagnóstico de la infección por Helicobacter pylori (H. pylori). Por tanto, es el método de elección en pacientes sometidos a gastroscopia. La mayoría de los kits requieren 24 h para obtener un resultado. En nuevo test ultrarrápido de la ureasa (TURU) de Biohit requiere menos de una hora. Objetivo: Determinar la exactitud diagnóstica del TURU. Método: Estudio multicéntrico, prospectivo y ciego, en el que se incluyó a pacientes dispépticos. Se obtuvieron 3 biopsias de antro y una de corpus durante la gastroscopia para análisis histológico estándar, TRU y TURU. El resultado del TURU se comprobó a los 1, 5, 30 y 60 min, mientras que el TRU se evaluó a lo largo de 24 h. La histología se utilizó como patrón oro. Resultados: Se incluyó a 144 pacientes, 68% mujeres, edad media 49 años, el 50% fueron positivos para H. pylori. TRU y TURU diagnosticaron correctamente el 85,9% y 90,0% de los casos, respectivamente. La duración media de espera para un resultado positivo del TRU fue 6 h. La sensibilidad, la especificidad y los valores predictivos negativo y positivo para el TRU fueron, respectivamente, del 82, el 90, el 89 y el 84%. Los resultados del TURU fueron equivalentes (el 85, el 94, el 94 y el 87%). Estos resultados mejoraron al excluir los pacientes que tomaban IBP (TRU: 86, 91, 93 y 83%; TURU: 91, 94, 96 y 89%). La comparación de distribución de diagnósticos correctos entre TRU y TURU no encontró diferencias estadísticamente significativas (test de McNemar p=0,3) pero existe una tendencia a mejores resultados con el TURU. Conclusión: El TURU es equivalente (o algo superior) al TRU tradicional en el diagnóstico de la infección por H. pylori y obtiene los resultados en menos de una hora (AU)

Prevalence of Malnutrition and Nutritional Characteristics of Patients With Inflammatory Bowel Disease.

BACKGROUND AND AIMS: This study sought to determine the prevalence of malnutrition in patients with inflammatory bowel disease, to analyse the dietary beliefs and behaviours of these patients, to study their body composition, to evaluate their muscular strength and to identify the factors associated with malnutrition in these patients. METHODS: This was a prospective, multicentre study. Crohn's disease and ulcerative colitis patients from 30 Spanish centres, from the outpatient clinics, were included. A questionnaire of 11 items was applied to obtain data from patients' dietary behaviour and beliefs. Patients who accepted were evaluated to assess their nutritional status using Subjective Global Assessment and body mass index. Body composition was evaluated through bioelectrical impedance. RESULTS: A total of 1271 patients were included [51% women, median age 45 years, 60% Crohn's disease]. Of these, 333 patients underwent the nutritional evaluation. A total of 77% of patients declared that they avoided some foods to prevent disease relapse. Eighty-six per cent of patients avoided some foods when they had disease activity because of fear of worsening the flare. Sixty-seven per cent of patients modified their dietary habits after disease diagnosis. The prevalence of malnutrition was 16% [95% confidence interval = 12-20%]. In the multivariate analysis, history of abdominal surgery, active disease and avoidance of some foods during flares were associated with higher risk of malnutrition. CONCLUSIONS: The prevalence of malnutrition in inflammatory bowel disease patients was high. We identified some predictive factors of malnutrition. Most of the patients had self-imposed food restrictions, based on their beliefs.

RESULTS: 144 patients were included, 68% female, with a mean age of 49 years old; 50% were H. pylori positive. RUT and URUT diagnoses were correct in 85.9% and 90% of the cases, respectively. The mean waiting time for a positive RUT result was 6h. The sensitivity, specificity, and positive and negative predictive values for RUT were, respectively, 82%, 90%, 89% and 84%. The URUT's results were similar (85%, 94%, 94% and 87%). These figures improved when patients taking PPIs were excluded (RUT: 86%, 91%, 93% and 83%; URUT: 91%, 94%, 96% and 89%). No statistically significant differences were found when comparing RUT and URUT distributions of correct diagnoses (McNemar's Test, p=0.3) but there was a tendency towards better results with the URUT. CONCLUSION: The URUT is equivalent to (or slightly better than) the traditional RUT in diagnosing H. pylori infection, and provides results in less than an hour.

IV Conferencia Española de Consenso sobre el tratamiento de la infección por Helicobacter pylor / IV Spanish Consensus Conference on Helicobacter pyloriinfection treatment

La infección por Helicobacter pylori afecta aproximadamente al 50% de la población española y es causante de la gastritis crónica, la úlcera péptica y el cáncer gástrico. Se han llevado a cabo hasta el momento, en nuestro país, 3 reuniones de Consenso sobre el manejo de la infección por H. pylori (la última de ellas en 2012). Los cambios en los esquemas de tratamiento y la creciente evidencia disponible al respecto han justificado la organización de esta IV Conferencia Española de Consenso en marzo de 2016, centrada en el tratamiento de esta infección. Participaron 19 expertos sobre el tema, que realizaron una búsqueda sistemática de la evidencia científica y elaboraron una serie de recomendaciones que fueron sometidas a un proceso de interacción de votaciones anónimas seriadas mediante metodología Delphi. Para clasificar la evidencia científica y la fuerza de las recomendaciones se utilizó el sistema GRADE. Este consenso establece, como punto de partida, un aumento de la exigencia en la eficacia de los tratamientos recomendados, que deben alcanzar, o preferiblemente superar, el 90% de curación al ser administrados de forma empírica. De este modo, tanto en primera como en segunda línea se recomiendan tratamientos cuádruples con o sin bismuto, generalmente prescritos durante 14días. El tratamiento cuádruple sin bismuto concomitante, que incluye un inhibidor de la bomba de protones, claritromicina, amoxicilina y metronidazol, se recomienda como primera línea. En el presente consenso se revisan también con detalle otras alternativas de tratamiento tanto de primera línea como de rescate

Helicobacter pylori approximately infect 50% of Spanish population and causes chronic gastritis, peptic ulcer and gastric cancer. Until now, three consensus meetings on H. pyloriinfection had been performed in Spain (the last in 2012). The changes in the treatment schemes, and the increasing available evidence, have justified organizing the IV Spanish Consensus Conference (March 2016), focused on the treatment of this infection. Nineteen experts participated, who performed a systematic review of the scientific evidence and developed a series of recommendation that were subjected to an anonymous Delphi process of iterative voting. Scientific evidence and the strength of the recommendation were classified using GRADE guidelines. As starting point, this consensus increased the minimum acceptable efficacy of recommended treatments that should reach, or preferably surpass, the 90% cure rate when prescribed empirically. Therefore, only quadruple therapies (with or without bismuth), and generally lasting 14 days, are recommended both for first and second line treatments. Non-bismuth quadruple concomitant regimen, including a proton pump inhibitor, clarithromycin, amoxicillin and metronidazole, is recommended as first line. In the present consensus, other first line alternatives and rescue treatments are also reviewed and recommended
