RESUMO

More than 10 million Europeans show signs of mild cognitive impairment (MCI), a transitional stage between normal brain aging and dementia stage memory disorder. The path MCI takes can be divergent; while some maintain stability or even revert to cognitive norms, alarmingly, up to half of the cases progress to dementia within 5 years. Current diagnostic practice lacks the necessary screening tools to identify those at risk of progression. The European patient experience often involves a long journey from the initial signs of MCI to the eventual diagnosis of dementia. The trajectory is far from ideal. Here, we introduce the AI-Mind project, a pioneering initiative with an innovative approach to early risk assessment through the implementation of advanced artificial intelligence (AI) on multimodal data. The cutting-edge AI-based tools developed in the project aim not only to accelerate the diagnostic process but also to deliver highly accurate predictions regarding an individual's risk of developing dementia when prevention and intervention may still be possible. AI-Mind is a European Research and Innovation Action (RIA H2020-SC1-BHC-06-2020, No. 964220) financed between 2021 and 2026. First, the AI-Mind Connector identifies dysfunctional brain networks based on high-density magneto- and electroencephalography (M/EEG) recordings. Second, the AI-Mind Predictor predicts dementia risk using data from the Connector, enriched with computerized cognitive tests, genetic and protein biomarkers, as well as sociodemographic and clinical variables. AI-Mind is integrated within a network of major European initiatives, including The Virtual Brain, The Virtual Epileptic Patient, and EBRAINS AISBL service for sensitive data, HealthDataCloud, where big patient data are generated for advancing digital and virtual twin technology development. AI-Mind's innovation lies not only in its early prediction of dementia risk, but it also enables a virtual laboratory scenario for hypothesis-driven personalized intervention research. This article introduces the background of the AI-Mind project and its clinical study protocol, setting the stage for future scientific contributions.

RESUMO

OBJECTIVES: The objective is to assess the role of functional, clinical, and analytic parameters in predicting mortality in older patients hospitalized due to COVID-19. DESIGN: Cohort study with a mean follow-up of 12.8 days. SETTING: Public university hospital (Madrid, Spain). PARTICIPANTS: 499 patients 80 and above consecutively admitted to a Spanish public university hospital between 4 March 2020 and 16 May 2020. MEASUREMENTS: Mortality was the main outcome. Data of sociodemographic variables (age, sex, living), comorbidities, polypharmacy, functional status, date of hospital admission and length of stay was recorded. Clinical symptoms, laboratory and X-ray findings were collected at time of admission. For multivariant analysis, logistic regressions were performed to identify risk factors for death. RESULTS: Mean age was 86.7±4.4 with 37% of death. Mortality was associated with male gender [odds ratio (OR) 1.50; 95% confidence interval (CI) 1.01-2.24], with a 5-points increase on Barthel Index [OR 1.01 (95%CI 1.00-1.02)], higher Charlson Index score [OR 1.13 (95%CI 1.02-1.26)] and comorbidities [OR 1.28 (95%CI 1.06-1.53)], hyperpolipharmacy [OR 2.00 (95%CI 1.04-3.82)], unilateral pneumonia [OR 1.83 (95%CI 1.01-3.30)], higher levels of C-reactive protein [OR 1.09 (95%CI 1.06-1.12)] and creatine [OR 1.48 (95%CI 1.15-1.89)]. Higher oxygen levels were a protective factor [OR 0.92 (95%CI 0.89-0.95)]. CONCLUSIONS: Functional status, being male, a higher burden of comorbidities, hyperpolipharmacy, unilateral pneumonia and some laboratory parameters predict in-hospital mortality in this older population. The knowledge of these mortality risk factors should be used to improve the survival of older hospitalized patients.

RESUMO

NAFLD is an important public health issue closely associated with the pervasive epidemics of diabetes and obesity. Yet, despite NAFLD being among the most common of chronic liver diseases, the biological factors responsible for its transition from benign nonalcoholic fatty liver (NAFL) to NASH remain unclear. This lack of knowledge leads to a decreased ability to find relevant animal models, predict disease progression, or develop clinical treatments. In the current study, we used multiple mouse models of NAFLD, human correlation data, and selective gene overexpression of steroidogenic acute regulatory protein (StarD1) in mice to elucidate a plausible mechanistic pathway for promoting the transition from NAFL to NASH. We show that oxysterol 7α-hydroxylase (CYP7B1) controls the levels of intracellular regulatory oxysterols generated by the "acidic/alternative" pathway of cholesterol metabolism. Specifically, we report data showing that an inability to upregulate CYP7B1, in the setting of insulin resistance, results in the accumulation of toxic intracellular cholesterol metabolites that promote inflammation and hepatocyte injury. This metabolic pathway, initiated and exacerbated by insulin resistance, offers insight into approaches for the treatment of NAFLD.

RESUMO

Las Enfermedades cardiovasculares y el cáncer comparten factores de riesgo y son las principales causas de mortalidad y morbilidad en nuestro medio. De otro lado, el concepto cardiotoxicidad hace referencia a desarrollo de patologías cardiovasculares relacionadas con los tratamientos del cáncer. La cardio-oncología surge como subespecialidad dentro de cardiología, con el objetivo de desarrollar estrategias multidisciplinares de promoción, prevención y tratamiento de las alteraciones cardiovasculares en pacientes oncológicos en los diferentes niveles asistenciales y en colaboración con fundaciones y asociaciones de pacientes. Dentro de esta colaboración inter-especialidades, la Salud Laboral, a través de los médicos y enfermeros del trabajo que integran las Unidades Básicas sanitarias de los servicios de prevención, participa realizando, desde el ámbito laboral, el seguimiento y control de los trabajadores que han sido tratados de cáncer. El análisis de los riesgos del puesto, la vigilancia sanitaria específica y el análisis de la documentación clínica deben permitir a los especialistas determinar las limitaciones y capacidades residuales y valorar la aptitud para el trabajo de los pacientes oncológicos, para actuar en prevención y control de estas patologías. El grupo de cardio-onco-hematologia laboral presenta la Guía para el manejo coordinado de los trabajadores con cáncer y riesgo cardiovascular con el objetivo de ofrecer apoyo al profesional sanitario en el abordaje preventivo del riesgo cardiovascular en aquellas personas que, tras recibir tratamiento por un proceso oncológico se reincorporan al mundo laboral, y en los que se ha de realizar una valoración global y coordinada por: oncología, cardiología, hematología y los especialistas de las unidades básicas de Salud Laboral


Cardiovascular diseases and cancer share risk factors and are the main causes of mortality and morbidity in our environment. On the other hand, the concept of cardiotoxicity refers to the development of cardiovascular pathologies related to cancer treatments. Cardio-oncology emerges as a subspecialty within cardiology, with the objective of developing multidisciplinary strategies for the promotion, prevention and treatment of cardiovascular disorders in cancer patients at different care levels and in collaboration with foundations and patient associations. Within this inter-specialties collaboration, Occupational Health, through the labour doctors and nurses that make up the Basic Health Units of the prevention services, participates by carrying out, from the workplace, the monitoring and control of the workers who have been treated for cancer. The risks position analysis, the specific sanitary surveillance and the clinical documentation analysis must allow the specialists to determine the limitations and residual capacities and assess the aptitude for the work of the oncological patients, to act in prevention and control of these pathologies. The labor cardio-onco-hematology group presents the Guide for the coordinated management of workers with cancer and cardiovascular risk with the aim of offering support to the healthcare professional in the preventive approach of cardiovascular risk in those who, after receiving treatment for a The oncological process is reincorporated into the world of work, and in which a global assessment must be carried out and coordinated by: oncology, cardiology, hematologic and the specialists of the basic units of Occupational Health

RESUMO

How plasma membrane (PM) cholesterol is controlled is poorly understood. Ablation of the gene encoding the ER stress steroidogenic acute regulatory-related lipid transfer domain (StarD)5 leads to a decrease in PM cholesterol content, a decrease in cholesterol efflux, and an increase in intracellular neutral lipid accumulation in macrophages, the major cell type that expresses StarD5. ER stress increases StarD5 expression in mouse hepatocytes, which results in an increase in accessible PM cholesterol in WT but not in StarD5-/- hepatocytes. StarD5-/- mice store higher levels of cholesterol and triglycerides, which leads to altered expression of cholesterol-regulated genes. In vitro, a recombinant GST-StarD5 protein transfers cholesterol between synthetic liposomes. StarD5 overexpression leads to a marked increase in PM cholesterol. Phasor analysis of 6-dodecanoyl-2-dimethylaminonaphthalene fluorescence lifetime imaging microscopy data revealed an increase in PM fluidity in StarD5-/- macrophages. Taken together, these studies show that StarD5 is a stress-responsive protein that regulates PM cholesterol and intracellular cholesterol homeostasis.

RESUMO

The aim of this paper was to more completely study the mitochondrial CYP27A1 initiated acidic pathway of cholesterol metabolism. The mitochondrial CYP27A1 initiated pathway of cholesterol metabolism (acidic pathway) is known to synthesize two well-described vital regulators of cholesterol/lipid homeostasis, (25R)-26-hydroxycholesterol (26HC) and 25-hydroxycholesterol (25HC). Both 26HC and 25HC have been shown to be subsequently 7α-hydroxylated by Cyp7b1; reducing their regulatory abilities and furthering their metabolism to chenodeoxycholic acid (CDCA). Cholesterol delivery into the inner mitochondria membrane, where CYP27A1 is located, is considered the pathway's only rate-limiting step. To further explore the pathway, we increased cholesterol transport into mitochondrial CYP27A1 by selectively increased expression of the gene encoding the steroidogenic acute transport protein (StarD1). StarD1 overexpression led to an unanticipated marked down-regulation of oxysterol 7α-hydroxylase (Cyp7b1), a marked increase in 26HC, and the formation of a third vital regulatory oxysterol, 24(S)-hydroxycholesterol (24HC), in B6/129 mice livers. To explore the further metabolism of 24HC, as well as, 25HC and 26HC, characterizations of oxysterols and bile acids using three murine models (StarD1 overexpression, Cyp7b1-/-, Cyp27a1-/-) and human Hep G2 cells were conducted. This report describes the discovery of a new mitochondrial-initiated pathway of oxysterol/bile acid biosynthesis. Just as importantly, it provides evidence for CYP7B1 as a key regulator of three vital intracellular regulatory oxysterol levels.

RESUMO

INTRODUCCIÓN: Las microhemorragias cerebrales (MHC) son depósitos de hemosiderina, fagocitados por macrófagos, que se visualizan como imágenes hipointensas en determinadas secuencias de adquisición T2 de resonancia magnética cerebral. Existen muchas incógnitas acerca de su fisiopatología y significado clínico. DESARROLLO: Revisión bibliográfica de los principales estudios epidemiológicos, clínicos y anatomopatológicos de MHC en la población general, en pacientes con enfermedad o riesgo vascular y en pacientes con deterioro cognitivo. Descripción de la prevalencia, factores de riesgo, mecanismos fisiopatológicos y posibles implicaciones clínicas de las MHC. CONCLUSIONES: La prevalencia de las MHC es muy variable (3-27% en la población general, 6-80% en pacientes con enfermedad o riesgo vascular, 16-45% en pacientes con deterioro cognitivo). Las MHC se asocian a la edad, a la enfermedad de Alzheimer y, en particular, a la enfermedad vascular (hemorrágica o isquémica) cerebral. El sustrato patológico es la lipohialinosis (MHC subcorticales) o la angiopatía amiloide cerebral (MHC lobulares). Las MHC contribuyen al deterioro cognitivo, posiblemente a través de una desconexión córtico-subcortical e intracortical, y se asocian a una mayor mortalidad, especialmente de causa vascular. Las MHC aumentan el riesgo de sufrir hemorragia cerebral, especialmente en pacientes con múltiples MHC lobulares (probable angiopatía amiloide cerebral), por lo que el tratamiento anticoagulante podría estar contraindicado en estos pacientes. En pacientes con menor riesgo de sangrado, los nuevos anticoagulantes orales y la realización de un seguimiento combinado -clínico y mediante resonancia magnética- podrían ser útiles en la toma de decisiones


INTRODUCTION: Brain microbleeds (BMB) are haemosiderin deposits contained within macrophages, which are displayed as hypointense images in some T2-weighted magnetic resonance imaging sequences. There are still many questions to be answered about the pathophysiology and clinical relevance of BMB. DEVELOPMENT: We conducted a literature review of the main epidemiological, clinical, and anatomical pathology studies of BMB performed in the general population, in patients at risk of or already suffering from a vascular disease, and in patients with cognitive impairment. We analysed the prevalence of BMB, risk factors, and potential pathophysiological mechanisms and clinical implications. CONCLUSIONS: The prevalence of BMB is highly variable (3%-27% in the general population, 6%-80% in patients with vascular risk factors or vascular disease, and 16%-45% in patients with cognitive impairment). BMB are associated with ageing, Alzheimer disease (AD), and in particular haemorrhagic or ischaemic cerebrovascular disease. The pathological substrate of BMB is either lipohyalinosis (subcortical BMB) or cerebral amyloid angiopathy (lobar BMB). BMB exacerbate cognitive impairment, possibly through cortical-subcortical and intracortical disconnection, and increase the risk of death, mostly due to vascular causes. BMB also increase the risk of cerebral haemorrhage, particularly in patients with multiple lobar BMB (probable erebral amyloid angiopathy). Therefore, anticoagulant treatment may be contraindicated in these patients. In patients with lower risk of bleeding, the new oral anticoagulants and the combination of clinical and magnetic resonance imaging follow-up could be helpful in the decision-making process

RESUMO

Aging is an important risk factor for patients with atrial fibrillation. The estimated prevalence of atrial fibrillation in patients aged ≥80 years is 9-10%, and is associated with a four to five fold increased risk of embolic stroke, and with an estimated increased stroke risk of 1.45-fold per decade in aging. Older age is also associated with an increased risk of major bleeding with oral anticoagulant therapy. This review will focus on the role of oral anticoagulation with new oral anticoagulants, non-vitamin K antagonist in populations with common comorbid conditions, including age, chronic kidney disease, coronary artery disease, on multiple medication, and frailty. In patients 75 years and older, randomised trials have shown new oral anticoagulants to be as effective as warfarin, or in some cases superior, with an overall better safety profile, consistently reducing rates of intracranial haemorrhages. Prior to considering oral anticoagulant therapy in an elderly frail patient, a comprehensive assessment should be performed to include the risks and benefits, stroke risk, baseline kidney function, cognitive status, mobility and fall risk, multiple medication, nutritional status assessment, and life expectancy.

RESUMO

Objetivo. Estudiar el efecto de una intervención multidimensional en el pronóstico a 30 días en los ancianos frágiles dados de alta desde una unidad de corta estancia. Material y método. Estudio cuasiexperimental con una cohorte de control histórica. Se incluyeron pacientes frágiles (Identification of Senior at Risk≥2), de≥75 años, dados de alta desde la unidad de corta estancia durante 2 meses en 2013 (grupo control) y un año (2016; grupo de intervención). Se realizó una intervención basada en la activación de recursos, en función de los déficits detectados tras una valoración geriátrica abreviada, más la coordinación con Atención Primaria. La variable de resultado principal fue la presencia de algún resultado adverso (muerte o reingreso por cualquier causa o deterioro funcional grave) a los 30 días del alta. Resultados. Se incluyeron 137 (62,8%) pacientes en el grupo de intervención y 81 (37,2%) en el control. Dieciocho (13,1%) pacientes en el grupo de intervención y 29 (35,8%) en el control presentaron algún evento adverso a los 30 días. Tras un análisis multivariable, se demostró que la realización de una intervención multidimensional fue un factor de protección para la presentación de algún evento adverso a los 30 días tras el alta (RR ajustado 0,40; IC 95% 0,23-0,68; p=0,001). Conclusiones. La realización de un plan de atención individualizado, basado en la activación de recursos, en función de los déficits detectados tras una valoración geriátrica abreviada, y la coordinación con Atención Primaria, entre los pacientes ancianos frágiles podría mejorar los resultados a los 30 días tras el alta desde una UCE


Objective. To study the effect of a multidimensional intervention on the prognosis at 30 days for frail elderly patients discharged from a short-stay unit. Material and method. A quasiexperimental study was conducted with a historical control cohort. We included frail patients (Identification of Seniors at Risk score≥2) 75 years of age or older, discharged from an short-stay unit over 2 months in 2013 (control group) and in 2016 (intervention group). An intervention was conducted based on the activation of resources, based on the deficiencies detected after an abbreviated geriatric assessment, in conjunction with Primary Care. The main endpoint was the presence of an adverse result (death or readmission for any cause or severe functional impairment) at 30 days of discharge. Results. We included 137 (62.8%) patients in the intervention group and 81 (37.2%) in the control group. Eighteen (13.1%) patients in the intervention group and 29 (35.8%) in the control group presented an adverse event at 30 days. A multivariate analysis showed that the implementation of a multidimensional intervention was a protective factor for presenting an adverse event at 30 days of discharge (adjusted RR 0.40; 95% CI 0.23-0.68; P=.001). Conclusions. The implementation of an individual care plan for frail elderly patients, based on the activation of resources according to the deficiencies detected after an abbreviated geriatric assessment and in conjunction with Primary Care, could improve the results at 30 days of discharge from an short-stay unit

RESUMO

OBJECTIVE: To derive a risk score to predict in-hospital mortality for very old patients with decompensated chronic heart failure (DCHF). METHODOLOGY: Retrospective cohort study that included patients ≥ 80 years admitted to a Geriatric Acute Care Unit with DCHF between January 2012 and December 2014. We analyzed 70 candidate risk factors and in-hospital mortality. We derived a risk model using multivariate logistic regression model and constructed a scale for scoring risk. We used bootstrapping techniques for the internal validation. RESULTS: We included 629 patients with mean age of 90 (SD5) years, 470 (73.1%) being women. Eighty-six (13.7%) patients died during the hospitalization. Factors included in the final risk model were NYHA class III-IV, severe functional dependence (Katz activities of daily living index < 2), infection as cause of exacerbation of heart failure, number of medications ≥ 8, albumin < 3 mg/dL, glomerular filtration rate < 60 mL/min, level of potassium in blood > 5.5 mEq/L and red blood cell distribution width (RDW) > 17%. In-hospital mortality in risk groups was 3.0, 4.6, 9.5, 15.1 and 36.3%, respectively. The area under ROC curve risk for score after bootstrapping was 0.77 (95%: CI 0.70-0.83). CONCLUSION: This risk score could be useful for stratifying risk for in-hospital mortality among very old patients admitted to hospital for DCHF.

RESUMO

El dolor irruptivo se define como una exacerbación aguda del dolor de rápida aparición, corta duración y de intensidad moderada o elevada, que ocurre de forma espontánea o en relación con un evento predecible o no predecible a pesar de existir un dolor basal estabilizado y controlado. Sin embargo, existen dudas sobre la definición, terminología, epidemiología y valoración del dolor irruptivo sin una clara contestación y consenso, especialmente en la población anciana. En esta revisión no sistematizada se intentarán sintetizar y resumir los aspectos más relevantes del dolor irruptivo en los ancianos en base a las escasas publicaciones existentes en dicho grupo poblacional (AU)


Breakthrough pain is defined as an acute exacerbation of pain with rapid onset, short duration and moderate or high intensity, which occurs spontaneously or in connection with a predictable or unpredictable event despite there being stabilised and controlled baseline pain. However, there are doubts about the definition, terminology, epidemiology, and assessment of breakthrough pain, with no clear answers or consensus, especially in the elderly population. This non-systematic review summarises the most important aspects of breakthrough pain in the elderly, based on the limited publications there are in that population group (AU)

RESUMO

La presencia de deterioro cognitivo genera cambios importantes tanto para el paciente como para su familia y para el personal sanitario que debe prestar cuidados adecuados. Un reconocimiento precoz de esta alteración va a permitir un diagnóstico y tratamiento adecuado, un apoyo psicosocial y educativo, así como la posibilidad de establecer unos planes de cuidados, de proyecto vital y económico. La abundancia de criterios y de clasificaciones pone de manifiesto el interés que despierta en la comunidad científica el problema de las alteraciones cognitivas observadas en el envejecimiento. Es obvio que se precisa unificación de criterios y la puesta en marcha de estudios longitudinales para llegar a conclusiones fiables. La valoración clínica de los diferentes dominios cognitivos debe incluir una cuidadosa historia clínica y la utilización de baterías neuropsicológicas diagnósticas. Podemos establecer, en primer lugar, que un instrumento de screening ideal debería ser aquel que se pudiese administrar en pocos minutos, además debe tener un punto de corte para identificar aquellos que precisen una valoración más completa para establecer un diagnóstico adecuado. La utilización de biomarcadores dinámicos se basa en la hipótesis de que estos marcadores tienen un modelo específico dependiente del tiempo. En primer lugar destaca la presencia de marcadores de amiloidosis y en un segundo paso los marcadores de neurodegeneración. La fragilidad cognitiva es un término emergente e inspirado en un potencial paralelo con el síndrome de fragilidad física. Se ha establecido que un subgrupo de pacientes con deterioro cognitivo presenta reducción en la capacidad de recuperación y un declinar funcional que interacciona con la fragilidad física. La evidencia sugiere que el estado cognitivo representa una importante dimensión del síndrome de fragilidad (AU)


The presence of cognitive impairment generates important changes in both affected individuals and their families and the health staff who must provide adequate care. Early identification of this alteration allows appropriate diagnosis and treatment and psychosocial and educational support, as well as the possibility of establishing care, life and financial plans. The interest of the scientific community in age-related cognitive alterations is demonstrated by the abundance of criteria and classifications. Obviously, there is a need to unify these criteria and implement longitudinal studies in order to reach reliable conclusions. Clinical assessment of the distinct cognitive domains should include careful history-taking and the use of diagnostic neuropsychological batteries. First, the ideal screening test would be one that could be administered in a few minutes, with a cut-off point that would identify patients requiring further assessment for correct diagnosis. The use of dynamic biomarkers is based on the hypothesis that they have a specific time-dependent model. These biomarkers include, firstly, markers of amyloidosis and, secondly, markers of neurodegeneration. Cognitive frailty is an emerging term inspired by a potential parallel with physical frailty syndrome. A subgroup of patients with cognitive impairment show a reduced capacity for recovery and functional decline that interact with physical frailty. The evidence suggests that cognitive status represents an important dimension of frailty syndrome (AU)

RESUMO

La enfermedad neumocócica invasiva (ENI) y la neumonía neumocócica (NN) suponen un grave problema de salud entre los adultos de mayor edad y aquellos con determinadas condiciones y patologías de base, entre los que destacan los inmunodeprimidos y algunos inmunocompetentes, que les hacen más susceptibles a la infección y favorecen cuadros de mayor gravedad y peor evolución. Entre las estrategias para prevenir la ENI y la NN se encuentra la vacunación, aunque las coberturas vacunales son más bajas de lo deseable. Actualmente, existen 2 vacunas disponibles para el adulto. La vacuna polisacárida (VNP23), que se emplea en mayores de 2 años de edad desde hace décadas, es la que mayor número de serotipos (23) incluye, pero no genera memoria inmunitaria, los niveles de anticuerpos disminuyen con el tiempo, provoca un fenómeno de tolerancia inmunitaria y no actúa sobre la colonización nasofaríngea. La vacuna conjugada (VNC13) puede emplearse a cualquier edad de la vida a partir de las 6 semanas de vida y genera una respuesta inmunitaria más potente que la VNP23 frente a la mayoría de los 13 serotipos en ella incluidos. En el año 2013 las 16 Sociedades Científicas más directamente relacionadas con los grupos de riesgo para padecer ENI publicamos un documento de Consenso con una serie de recomendaciones basadas en las evidencias científicas respecto a la vacunación antineumocócica en el adulto con condiciones especiales y patología de base. Se estableció un compromiso de discusión y actualización ante la aparición de nuevas evidencias. Fruto de este trabajo de revisión, presentamos una actualización del anterior documento junto a otras nuevas Sociedades Científicas donde destaca la recomendación por edad (AU)


Invasive pneumococcal disease (IPD) and pneumococcal pneumonia (PP) represent an important health problem among aging adults and those with certain underlying pathologies and some diseases, especially immunosuppressed and some immunocompetent subjects, who are more susceptible to infections and present greater severity and worse evolution. Among the strategies to prevent IPD and PP, vaccination has its place, although vaccination coverage in this group is lower than desirable. Nowadays, there are 2 vaccines available for adults. Polysacharide vaccine (PPV23), used in patients aged 2 and older since decades ago, includes a greater number of serotypes (23), but it does not generate immune memory, antibody levels decrease with time, causes an immune tolerance phenomenon, and have no effect on nasopharyngeal colonization. PCV13 can be used from children 6 weeks of age to elderly and generates an immune response more powerful than PPV23 against most of the 13 serotypes included in it. In the year 2013 the 16 most directly related to groups of risk of presenting IPD publised a series of vaccine recommendations based on scientific evidence regarding antipneumococcal vaccination in adults with underlying pathologies and special conditions. A commitment was made about updating it if new scientific evidence became available. We present an exhaustive revised document focusing mainly in recommendation by age in which some more Scientific Societies have been involved (AU)

RESUMO

Invasive pneumococcal disease (IPD) and pneumococcal pneumonia (PP) represent an important health problem among aging adults and those with certain underlying pathologies and some diseases, especially immunosuppressed and some immunocompetent subjects, who are more susceptible to infections and present greater severity and worse evolution. Among the strategies to prevent IPD and PP, vaccination has its place, although vaccination coverage in this group is lower than desirable. Nowadays, there are 2 vaccines available for adults. Polysacharide vaccine (PPV23), used in patients aged 2 and older since decades ago, includes a greater number of serotypes (23), but it does not generate immune memory, antibody levels decrease with time, causes an immune tolerance phenomenon, and have no effect on nasopharyngeal colonization. PCV13 can be used from children 6 weeks of age to elderly and generates an immune response more powerful than PPV23 against most of the 13 serotypes included in it. In the year 2013 the 16 most directly related to groups of risk of presenting IPD publised a series of vaccine recommendations based on scientific evidence regarding anti-pneumococcal vaccination in adults with underlying pathologies and special conditions. A commitment was made about updating it if new scientific evidence became available. We present an exhaustive revised document focusing mainly in recommendation by age in which some more Scientific Societies have been involved.
