Prevalence of severe esophagitis in Spain. Results of the PRESS study (Prevalence and Risk factors for Esophagitis in Spain: A cross-sectional study)
Background The current prevalence of esophagitis in southern Europe is unknown. In addition, the risk factors for reflux esophagitis are not fully understood. Objective The objective of this article is to assess the prevalence and risk factors for esophagitis in Spain. Methods A prospective, observational, cross-sectional, multicenter study (PRESS study) was conducted among 31 gastrointestinal endoscopy units throughout Spain. A total of 1361 patients undergoing upper gastrointestinal endoscopy were enrolled. Sociodemographic, clinical and treatment data were recorded. Results A total of 95% of patients were Caucasian and 52% were male (mean age: 5317 years). The most frequent symptoms prompting endoscopy were heartburn (40%), regurgitation (26%) and dysphagia (15%). Fifty-four percent of patients undergoing endoscopy were receiving proton pump inhibitor (PPI) treatment. Esophagitis (mainly mild-moderate) was present in 154 (12.4%) patients. The severe form was recorded in only 11 (0.8%) patients. Multivariate analysis results indicated that the likelihood of esophagitis was higher in men (OR=1.91, 95% CI=1.31-2.78), in patients with high GERD-Q scores (OR=1.256, 95% CI=1.176-1.343), weight increase (OR=1.014, 95% CI=1.003-1.025) and high alcohol consumption (OR=2.49, 95% CI=1.16-5.36). Conclusion Severe esophagitis is a rare finding in the Spanish population. Male gender, high GERD-Q score, weight increase and high alcohol consumption are main risk factors for its appearance
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
Evaluation of a New Monoclonal Chemiluminescent Immunoassay Stool Antigen Test for the Diagnosis of Helicobacter pylori Infection: A Spanish Multicentre Study
The stool antigen test (SAT) represents an attractive alternative for detection of Helicobacter pylori. The aim of this study was to assess the accuracy of a new SAT, the automated LIAISON(R) Meridian H. pylori SA based on monoclonal antibodies, compared to the defined gold standard C-13-urea breath test (UBT). This prospective multicentre study (nine Spanish centres) enrolled patients >= 18 years of age with clinical indication to perform UBT for the initial diagnosis and for confirmation of bacterial eradication. Two UBT methods were used: mass spectrometry (MS) including citric acid (CA) or infrared spectrophotometry (IRS) without CA. Overall, 307 patients (145 naive, 162 with confirmation of eradication) were analysed. Using recommended cut-off values (negative SAT = 1.10) the sensitivity, specificity, positive predictive value, negative predictive value and accuracy were 67%, 97%, 86%, 92% and 91%, respectively, obtaining an area under the receiver operating characteristic (ROC) curve (AUC) of 0.85. Twenty-eight patients, including seven false positives and 21 false negatives, presented a discordant result between SAT and UBT. Among the 21 false negatives, four of six tested with MS and 11 of 15 tested with IRS presented a borderline UBT delta value. In 25 discordant samples, PCR targeting H. pylori DNA was performed to re-assess positivity and SAT accuracy was re-analysed: sensitivity, specificity, positive predictive value, negative predictive value, accuracy and AUC were 94%, 97%, 86%, 99%, 97% and 0.96, respectively. The new LIAISON(R) Meridian H. pylori SA SAT showed a good accuracy for diagnosis of H. pylori infection

An Insulin-to-Insulin Regulatory Network Orchestrates Phenotypic Specificity in Development and Physiology
Insulin-like peptides (ILPs) play highly conserved roles in development and physiology. Most animal genomes encode multiple ILPs. Here we identify mechanisms for how the forty Caenorhabditis elegans ILPs coordinate diverse processes, including development, reproduction, longevity and several specific stress responses. Our systematic studies identify an ILP-based combinatorial code for these phenotypes characterized by substantial functional specificity and diversity rather than global redundancy. Notably, we show that ILPs regulate each other transcriptionally, uncovering an ILP-to-ILP regulatory network that underlies the combinatorial phenotypic coding by the ILP family. Extensive analyses of genetic interactions among ILPs reveal how their signals are integrated. A combined analysis of these functional and regulatory ILP interactions identifies local genetic circuits that act in parallel and interact by crosstalk, feedback and compensation. This organization provides emergent mechanisms for phenotypic specificity and graded regulation for the combinatorial phenotypic coding we observe. Our findings also provide insights into how large hormonal networks regulate diverse traits
CagA-positive Helicobacter pylori infection is not associated with decreased risk of Barrett's esophagus in a population with high H. pylori infection rate
BACKGROUND & AIM: The role that H. pylori infection plays in the development of and Barrett's esophagus (BE) is uncertain. We tested the hypothesis that infection with cagA+ Helicobacter pylori strains protects against the development of BE. METHODS: We studied 104 consecutive patients, residents in an area with a high prevalence of H. pylori infection, with BE and 213 sex- and age-matched controls. H. pylori infection and CagA antibody status were determined by western blot serology. RESULTS: H. pylori prevalence was higher in patients with BE than in controls (87.5% vs. 74.6%; OR. 2.3; 95% CI: 1.23–4.59). Increasing age was associated with a higher prevalence of H. pylori (p < 0.05). The prevalence of CagA+ H. pylori serology was similar in patients with BE and controls (64.4% vs. 54.5%; NS). Type I H. pylori infection (CagA+ and VacA+) was similar in patients with BE and controls (44.2% vs. 41.3%; NS). Logistic regression analysis identified alcohol (O.R. 7.09; 95% CI 2.23–22.51), and H. pylori infection (OR: 2.41; 95%CI: 1.20–4.84) but not CagA+ serology as independent factors. CONCLUSION: Neither H. pylori infection nor H. pylori infection by CagA+ strains reduce the risk of BE in a population with high prevalence of H. pylori infection
European Registry on Helicobacter pylori Management: Effectiveness of First and Second-Line Treatment in Spain
The management of Helicobacter pylori infection has to rely on previous local effectiveness due to the geographical variability of antibiotic resistance. The aim of this study was to evaluate the effectiveness of first and second-line H. pylori treatment in Spain, where the empirical prescription is recommended. A multicentre prospective non-interventional registry of the clinical practice of European gastroenterologists concerning H. pylori infection (Hp-EuReg) was developed, including patients from 2013 until June 2019. Effectiveness was evaluated descriptively and through a multivariate analysis concerning age, gender, presence of ulcer, proton-pump inhibitor (PPI) dose, therapy duration and compliance. Overall, 53 Spanish hospitals were included, and 10,267 patients received a first-line therapy. The best results were obtained with the 10-day bismuth single-capsule therapy (95% cure rate by intention-to-treat) and with both the 14-day bismuth-clarithromycin quadruple (PPI-bismuth-clarithromycin-amoxicillin, 91%) and the 14-day non-bismuth quadruple concomitant (PPI-clarithromycin-amoxicillin-metronidazole, 92%) therapies. Second-line therapies were prescribed to 2448 patients, with most-effective therapies being the triple quinolone (PPI-amoxicillin-levofloxacin/moxifloxacin) and the bismuth-levofloxacin quadruple schemes (PPI-bismuth-levofloxacin-amoxicillin) prescribed for 14 days (92%, 89% and 90% effectiveness, respectively), and the bismuth single-capsule (10 days, 88.5%). Compliance, longer duration and higher acid inhibition were associated with higher effectiveness. "Optimized" H. pylori therapies achieve over 90% success in Spain
EoE CONNECT, the European Registry of Clinical, Environmental, and Genetic Determinants in Eosinophilic Esophagitis: rationale, design, and study protocol of a large-scale epidemiological study in Europe
Background: The growing prevalence of eosinophilic esophagitis (EoE) represents a considerable burden to patients and health care systems. Optimizing cost-effective management and identifying mechanisms for disease onset and progression are required. However, the paucity of large patient cohorts and heterogeneity of practice hinder the defining of optimal management of EoE. Methods: EoE CONNECT is an ongoing, prospective registry study initiated in 2016 and currently managed by EUREOS, the European Consortium for Eosinophilic Diseases of the Gastrointestinal Tract. Patients are managed and treated by their responsible specialists independently. Data recorded using a web-based system include demographic and clinical variables; patient allergies; environmental, intrapartum, and early life exposures; and family background. Symptoms are structurally assessed at every visit; endoscopic features and histological findings are recorded for each examination. Prospective treatment data are registered sequentially, with new sequences created each time a different treatment (active principle, formulation, or dose) is administered to a patient. EoE CONNECT database is actively monitored to ensure the highest data accuracy and the highest scientific and ethical standards. Results: EoE CONNECT is currently being conducted at 39 centers in Europe and enrolls patients of all ages with EoE. In its aim to increase knowledge, to date EoE CONNECT has provided evidence on the effectiveness of first- and second-line therapies for EoE in clinical practice, the ability of proton pump inhibitors to induce disease remission, and factors associated with improved response. Drug effects to reverse fibrous remodeling and endoscopic features of fibrosis in EoE have also been assessed. Conclusion: This prospective registry study will provide important information on the epidemiological and clinical aspects of EoE and evidence as to the real-world and long-term effectiveness and safety of therapy. These data will potentially be a vital benchmark for planning future EoE health care services in Europe
Accurate and timely diagnosis of Eosinophilic Esophagitis improves over time in Europe. An analysis of the EoE CONNECT Registry
BACKGROUND: Poor adherence to clinical practice guidelines for eosinophilic esophagitis (EoE) has been described and the diagnostic delay of the disease continues to be unacceptable in many settings. OBJECTIVE: To analyze the impact of improved knowledge provided by the successive international clinical practice guidelines on reducing diagnostic delay and improving the diagnostic process for European patients with EoE. METHODS: Cross‐sectional analysis of the EoE CONNECT registry based on clinical practice. Time periods defined by the publication dates of four major sets of guidelines over 10 years were considered. Patients were grouped per time period according to date of symptom onset. RESULTS: Data from 1,132 patients was analyzed and median (IQR) diagnostic delay in the whole series was 2.1 (0.7‐6.2) years. This gradually decreased over time with subsequent release of new guidelines (p < 0.001), from 12.7 years up to 2007 to 0.7 years after 2017. The proportion of patients with stricturing of mixed phenotypes at the point of EoE diagnosis also decreased over time (41.3% vs. 16%; p < 0.001), as did EREFS scores. The fibrotic sub‐score decreased from a median (IQR) of 2 (1‐2) to 0 (0‐1) when patients whose symptoms started up to 2007 and after 2017 were compared (p < 0.001). In parallel, symptoms measured with the Dysphagia Symptoms Score reduced significantly when patients with symptoms starting before 2007 and after 2012 were compared. A reduction in the number of endoscopies patients underwent before the one that achieved an EoE diagnosis, and the use of allergy testing as part of the diagnostic workout of EoE, also reduced significantly over time (p = 0.010 and p < 0.001, respectively). CONCLUSION: The diagnostic work‐up of EoE patients improved substantially over time at the European sites contributing to EoE CONNECT, with a dramatic reduction in diagnostic delay
Global Perspectives on Task Shifting and Task Sharing in Neurosurgery.
BACKGROUND: Neurosurgical task shifting and task sharing (TS/S), delegating clinical care to non-neurosurgeons, is ongoing in many hospital systems in which neurosurgeons are scarce. Although TS/S can increase access to treatment, it remains highly controversial. This survey investigated perceptions of neurosurgical TS/S to elucidate whether it is a permissible temporary solution to the global workforce deficit. METHODS: The survey was distributed to a convenience sample of individuals providing neurosurgical care. A digital survey link was distributed through electronic mailing lists of continental neurosurgical societies and various collectives, conference announcements, and social media platforms (July 2018-January 2019). Data were analyzed by descriptive statistics and univariate regression of Likert Scale scores. RESULTS: Survey respondents represented 105 of 194 World Health Organization member countries (54.1%; 391 respondents, 162 from high-income countries and 229 from low- and middle-income countries [LMICs]). The most agreed on statement was that task sharing is preferred to task shifting. There was broad consensus that both task shifting and task sharing should require competency-based evaluation, standardized training endorsed by governing organizations, and maintenance of certification. When perspectives were stratified by income class, LMICs were significantly more likely to agree that task shifting is professionally disruptive to traditional training, task sharing should be a priority where human resources are scarce, and to call for additional TS/S regulation, such as certification and formal consultation with a neurosurgeon (in person or electronic/telemedicine). CONCLUSIONS: Both LMIC and high-income countries agreed that task sharing should be prioritized over task shifting and that additional recommendations and regulations could enhance care. These data invite future discussions on policy and training programs
Quimioprevención en adenocarcinoma de esófago
El adenocarcinoma de esófago (ACE) ha aumentado notablemente su incidencia en las últimas décadas, en los países occidentales; lo que se ha asociado a un crecimiento paralelo de la incidencia y prevalencia de los síntomas atribuibles a la Enfermedad por Reflujo Gastroesofágico
(ERGE) y a un aumento de los diagnósticos de esófago de Barrett (EB). Ambas situaciones son
consideradas como factores de riesgo para el desarrollo de ACE. Se han propuesto diferentes vías, incluyendo la sobreexpresión de los isoenzimas de la ciclooxigenasa (COX), para explicar el proceso de carcinogénesis que transcurre entre la mucosa esofágica normal, la esofagitis,
el EB y el ACE. La tasa de supervivencia en pacientes con ACE es muy baja, debido a los deficientes resultados del tratamiento quirúrgico, así como a los escasos beneficios aportados
por la quimio y radioterapia concomitantes. Diversas estrategias basadas en el diagnóstico precoz y seguimiento de las lesiones preneoplásicas han fracasado en conseguir un impacto global y significativo sobre el pronóstico del ACE. Estudios epidemiológicos y experimentales recientes sugieren que la quimioprevención podría ser útil en el manejo de los pacientes con ERGE, y especialmente en aquellos con EB. La terapia convencional con inhibidores de la bomba de protones (IBP) es eficaz para reducir la exposición ácida esofágica, mejorar los síntomas por el reflujo y curar las lesiones inflamatorias, pero probablemente no es suficiente para evitar la progresión displásica del epitelio con metaplasia. El uso regular de inhibidores de la COX (aspirina y otros antiinflamatorios no esteroides) es capaz de bloquear vías de carcinogénesis y disminuir la incidencia de ACE en modelos animales. En humanos, la asociación de IBP con inhibidores de la COX podría ser una estrategia segura y coste-efectiva, aunque no existen evidencias directas que lo corroboren. En lo que respecta a las indicaciones potenciales para quimioprevención de otros fármacos como la troglitazona, los antioxidantes, el tamoxifeno o los bloqueadores de los receptores de prostaglandinas, las evidencias científicas disponibles no permiten por el momento establecer recomendaciones sobre su empleo en la práctica clínica habitual
