Manifestaciones bucales de la enfermedad de Crohn y colitis ulcerosa en adultos mayores / Oral manifestations of Crohn´s disease and ulcerative colitis in of elderly adults

Objetivo: identificar las manifestaciones clínicas bucales de la enfermedad de Crohn y colitis ulcerosa en pacientes adultos mayores. Métodos: se efectuó un estudio descriptivo transversal con un universo de 50 adultos mayores, previamente diagnosticados por los especialistas gastroenterólogos, y prescritos con enfermedad de Crohn y colitis ulcerosa. Estos, confirmados por los hallazgos clínicos, histopatológicos y endoscópicos, remitidos a consulta estomatológica del Policlínico de Especialidades del Hospital Clinicoquirúrgico Universitario "Saturnino Lora Torres" de Santiago de Cuba, entre marzo de 2019 y marzo de 2020, practicándose el examen intrabucal, descripción de las lesiones bucales y su diagnóstico clínico. Para la recolección del dato primario se confeccionó un modelo con las variables: edad, sexo, enfermedad inflamatoria intestinal, localización anatómica, signos y síntomas clínicos orales en ambas patologías. Se creó una base de datos en SPSS versión 22.0 en Windows para el procesamiento y análisis de la información, usándose la técnica estadística descriptiva y agrupándose los datos en frecuencias absolutas y relativas. Resultados: en la serie resaltaron las personas de sexo femenino y el grupo de edades de 60 a 74 años, la pioestomatitis vegetante fue el signo bucal específico más común y la úlcera aftosa recurrente la lesión inespecífica de mayor predominio en ambas patologías. El dolor, el síntoma clínico de mayor afectación y el dorso de lengua el sitio de mayor predilección para su instalación. Conclusiones: las expresiones clínicas bucales más relevantes en pacientes adultos mayores con enfermedad de Crohn y colitis ulcerosa fueron la pioestomatitis vegetante y la úlcera aftosa recurrente.

Objective: Identify the oral clinical manifestations of Crohn´s disease and ulcerative colitis in elderly adults' patients. Methods: a cross-sectional descriptive study was carried out with a universe of 50 older adults previously diagnosed by gastroenterologist specialists, prescribing the presence of Crohn's disease and ulcerative colitis, confirmed by clinical, histopathologica and endoscopic findings, referred to the stomatological consultation of the Specialities Policlinic of the "Saturnino Lora Torres" University Clinical Surgical Hospital of Santiago de Cuba, from March 2019 to the same month of 2020, performing intraoral examination, description of oral lesions and their clinical diagnosis. For the collection of the primary data, a model was made with the variables: age, sex, inflammatory bowel disease, anatomical location, oral clinical signs and symptoms in both pathologies. A database was created in SPSS version 22.0 in Windows for the processing and analysis of the information, using the descriptive statistical technique and grouping the data in absolute and relative frequencies. Results: in the casuistry, females and the age group of 60 to 74 years prevailed, vegetative pyostomatitis was the most common specific oral sign and recurrent aphthous ulcer was the most prevalent non-specific lesion in both pathologies, pain being the most affecting clinical symptom and the back of the tongue is the most preferred site for its installation. Conclusions: the most relevant oral clinical expressions in elderly patients adults with Crohn´s disease and ulcerative colitis were pyostomatitis vegetative and recurrent aphthous ulcer.

Long-term treatment with nebulized colistin in oncological patients with recurrent respiratory infections

Objectives: To assess the efficacy of long-term treatment with nebulized colistin in reducing the number of respiratory infections, emergency consultations and hospitalizations in oncological patients.MethodsA retrospective, observational, single-centre study including patients with solid or haematologic malignancies, or pulmonary GVHD after HSTC who received treatment with nebulized colistin for at least six-months to prevent recurrent respiratory infections (July 2010 to June 2017).ResultsTwelve patients were included (median age: 54.4, range: 23–85), 7 with solid malignancies and 5 with haematologic malignancies (2 with pulmonary GVHD). Pseudomonas aeruginosa was the most frequent microorganism in sputum cultures (11/12 patients), all strains were susceptible to colistin. There was a statistically significant reduction (p=0.01) in respiratory infections in the six-month period after starting colistin (median: 1, range: 0–4) compared to the six-month period before (median: 4, range: 1–8). There was also a reduction in emergency consultations (precolistin: median: 1.50, range: 0–3; postcolistin: median: 0, range: 0–3) and hospitalizations (precolistin: median: 1.50, range: 0–3; postcolistin: median: 0, range: 0–3) due to respiratory infections. No colistin-resistant strains were identified.ConclusionsLong-term treatment with nebulized colistin may be useful to reduce the number of exacerbations in oncological patients with recurrent respiratory infections.

[Non-antibiotic Prophylaxis of Infections]. / Nicht-antibiotische Prophylaxe von Infekten.

Non-antibiotic Prophylaxis of Infections Abstract. The increasing resistance to antibiotics makes the search for non-antibiotic alternatives for the treatment and prevention of - above all - respiratory and urinary tract infections crucial. Potential non-antibiotic approaches include phytopharmaceuticals (Echinacea purpurea, Pelargonium sidoides, cranberry extract), zinc, immunostimulants (OM-85 BV, OM-89), and behavior modifications. Some of these approaches are promising options; however, a high level of evidence is required before specific recommendations for their use can be made.

Impacto de la endoglina y de otros marcadores de angiogénesis en las varices recurrentes. Resultados preliminaries / Impact of endoglin and other angiogenesis markers on recurrent varicose veins. Preliminary results

Introducción: después de una cirugía convencional de las varices (crosectomía y stripping de la safena interna) existe un importante porcentaje de recidivas que ocasiona un problema clínico, social y económico. Su etiopatogenia no está bien esclarecida. Objetivo: investigar en pacientes con varices (no recidivadas y recidivadas) la expresión de diferentes moléculas implicadas en los procesos de neovascularización, infl amación e hipoxia. Métodos: 41 pacientes sometidos a cirugía convencional de varices divididos en dos grupos: varices no recidivadas (n = 24) y varices recidivadas (n = 17). En ambos grupos se determinaron en la pared de la vena safena interna a nivel del cayado safenofemoral mediante RT-PCR a tiempo real los siguientes marcadores angiogénicos: endoglina, factor de crecimiento del endotelio vascular (VEGF-A), sus receptores 1 y 2 (VEGFR1 o FLTI), (VEGFR2 o KDR) y el factor inducible por hipoxia (HIF-1A). Todos los pacientes fi rmaron por escrito un consentimiento para participar en el estudio. Resultados: en los pacientes con recidiva varicosa se aprecia, a nivel de la pared venosa, una superior expresión de endoglina (p < 0,05), VEGF-A (p < 0,05), FLT1 (p < 0,001) y KDR (p < 0,001) respecto del grupo de varices no recidivadas. No se observaron diferencias signifi cativas respecto a HIF-1A. Conclusión: existe un aumento de los marcadores de angiogénesis, incluida la endoglina, en las muestras de pacientes portadores de varices con recidivas

Introduction: after conventional surgery for varicose veins (crosectomy and stripping of the internal saphenous)there is a significant percentage of recurrences which cause a clinical, social and economic problem. Its etiopathogenesis is not clear.Objective: to investigate in patients with varicose veins (non-recurrent and recurrent), the expression of differentmolecules involved in the processes of neovascularization, inflammation and hypoxia.Methods: 41 patients undergoing conventional varicose vein surgery, divided into two groups: non-recurrentvaricose veins (n = 24) and recurrent varicose veins (n = 17). In both groups, the following angiogenic markers weredetermined in the wall of the internal saphenous vein at the level of the saphenous-femoral arch, by means of realtime RT-PCR: endoglin, vascular endothelial growth factor (VEGF-A), its receptors 1 and 2 (VEGFR1 or FLTI), (VEGFR2or KDR), and hypoxia-inducible factor (HIF-1A). All patients signed a written consent to participate in the study.Results: in patients with varicose recurrence, a higher expression of endoglin (p < 0.05), VEGF-A (p < 0.05), FLT1(p < 0.001) and KDR (p < 0.001) is appreciated in respect to the group of non-recurrent varicose veins. No significantdifferences were observed with respect to HIF-1A.Conclusion: there is an increase in angiogenesis markers, including endoglin, in samples from patients with recurrent varicose veins

Inmunodeficiencia primaria combinada

RESUMEN Introducción: Las inmunodeficiencias primarias son enfermedades genéticas. Están constituidas por más de 200 enfermedades que tienen en común las infecciones recurrentes. La inmunodeficiencia combinada se caracteriza por episodios de sepsis recurrentes del aparato respiratorio, digestivo y de piel sobre todo por gérmenes oportunistas. El cuadro clínico es muy variable y se conocen múltiples fenotipos clínicos. Objetivo: Evaluar las manifestaciones clínicas e inmunológicas de la inmunodeficiencia primaria combinada no grave a través de un caso. Presentación de caso: Se trata un lactante de 8 meses de edad, masculino, blanco, que presentó múltiples infecciones respiratorias y digestivas, intolerancia a la leche, asociado a sibilancias recurrentes y manifestaciones exantemáticas. Tuvo varios ingresos incluso en terapia intensiva por sepsis grave y cumplió tratamientos con penicilinas, cefalosporinas, sulfas, fosfocina, vancomicina y metronidazol. El estudio inmunológico reveló una marcada disminución de las subpoblaciones linfocitarias y concentraciones disminuidas de la subclase de IgG4. Se estableció el diagnóstico de inmunodeficiencia primaria del tipo combinada no grave. El tratamiento utilizado incluyó gammaglobulina endovenosa y el factor de transferencia. Se confirmó una mejoría clínica evidente. Conclusiones: Las infecciones recurrentes junto con los resultados de los estudios permitieron diagnosticar esta inmunodeficiencia primaria. El diagnóstico precoz y el tratamiento oportuno mejoran la calidad de vida del paciente.

ABSTRACT Introduction: Primary immunodeficiencies are genetic diseases. They are made up of more than 200 diseases that have recurrent infections in common. Combined immunodeficiency is characterized by recurrent episodes of sepsis of the respiratory, digestive and skin system, especially opportunistic germs. The clinical picture is highly variable and multiple clinical phenotypes are known. Objective: Assess the clinical and immunological manifestations of non-severe combined primary immunodeficiency through a case. Case presentation: 8-month-old male, white infant who presented multiple respiratory and digestive infections, milk intolerance, associated with recurrent wheezing and exanthematic manifestations. He had several hospitalizations even in the intensive care service due to severe sepsis and completed treatments with penicillins, cephalosporins, sulfas, phosphocin, vancomycin and metronidazole. The immunological study revealed a marked decrease in lymphocyte subpopulations and decreased concentrations of the IgG4 subclass. The diagnosis of primary immunodeficiency of the non-severe combined type was established. The treatment used included intravenous gamma globulin and transfer factor. An evident clinical improvement was confirmed. Conclusions: The recurrent infections together with the results of the studies allowed to diagnose this primary immunodeficiency. Early diagnosis and timely treatment improve the patient's quality of life.

Caracterización de brote de dengue en barrios de parroquia Esmeraldas / Characterization of dengue outbreak in neighborhoods of Esmeraldas Parish

Uno de los principales problemas de los países tropicales son las enfermedades transmitidas por vectores. Entre ellas tenemos el dengue, zika y chikungunya, cuyo vector es un mosquito el Aedes aegyptiy Aedes albopictus. En el Ecuador, el dengue representa un problema prioritario en salud pública, desde el repunte del dengue en 1988 ha presentado varios ciclos epidémicos. Objetivo: Por lo anteriormente expuesto, se establece como objetivo de la investigación, caracterizar el brote de dengue que se presentó en el período Enero ­Febrero del año 2019, en barrios de la parroquia Esmeraldas, para evidenciar cuáles factores siguen recurrentes en la zona. Materiales y métodos: La investigación fue cuantitativa de corte transversal, descriptiva. La muestra fue no probabilística, los pacientes se presentaron de manera espontánea, se tomaron en cuenta variables como la edad, ocupación, síntomas, automedicación, tipo de medicamentos auto indicados, reinfección, viaje a zonas endémicas y condición de la vivienda. Las muestras fueron analizadas mediante prueba rápida Wondfo Whole Blood/Serum/Plasma test para NSI, IgG y IgM; en las instalaciones de la Escuela de Laboratorio Clínico de la Pontificia Universidad Católica de Ecuador (PUCESE). Los datos fueron procesados en Excel y analizados mediante el programa estadístico SPSS. Resultados: Los resultados que se obtuvieron permitieron caracterizar este brote relacionando las distintas variables, encontrando que en la mayoría de los casos es DSSA, dengue sin síntomas alarma y que no distingue edad, sexo, ni ocupación en el contagio. También, se encontró que las personas se automedican, en su mayoría, tratándose con paracetamol cuando los síntomas leves permanecen más de 5 días y no acuden al médico. Conclusión: Estos resultados nos permitieron concluir que este brote no presentó ninguna característica relevante que lo diferencie de los anteriores y que los factores y causas se mantienen, las personas desconocen las causas y prevención del contagio con el virus(AU)

One of the main problem in tropical countries is vector-borne diseases. Among them, we have Dengue, Zika and Chikungunya, whose vector is a mosquito Aedes aegypti and Aedes albopictus. In Ecuador, dengue represents a priority problem in public health, since the dengue rebound in 1988 has presented several epidemic cycles. Objective: For the above reasons, the objective of the research is to characterize the outbreak of dengue that occurred in the period January-February 2019, in neighborhoods of the parish of Esmeraldas, to show which factors are still recurrent in the area. Materials and methods: The research was quantitative, cross-sectional and descriptive. The sample was non-probabilistic, patients presented spontaneously, variables such as age, occupation, symptoms, self-medication, the type of self-prescribed medication, reinfection, travel to endemic areas and housing conditions were taken into account. Samples were analyzed by Wondfo Whole Blood/Serum/Plasma rapid test for NSI, IgG and IgM; at the facilities of the Clinical Laboratory School of the Pontificia Universidad Católica de Ecuador (PUCESE). Data were processed in Excel and analyzed using SPSS statistical software. The results: The results obtained allowed us to characterize this outbreak by relating the different variables, finding that in most cases it is DSSA, dengue without alarm symptoms and that it does not distinguish between age, sex or occupation in the contagion. It was also found that most people self-medicate, treating themselves with paracetamol when mild symptoms last more than 5 days and do not go to the doctor. Conclusion: These results allowed us to conclude that this outbreak did not present any relevant characteristic that differentiates it from previous outbreaks and that the factors and causes remain the same, people are unaware of the causes and prevention of infection with the virus(AU)

A genetic risk score predicts recurrent events after myocardial infarction in young adults.

INTRODUCTION AND OBJECTIVES: To evaluate whether a genetic risk score (GRS) improves prediction of recurrent events in young nondiabetic patients presenting with an acute myocardial infarction (AMI) and identifies a more aggressive form of atherosclerosis. METHODS: We conducted a prospective study with consecutive nondiabetic patients aged <55 years presenting with AMI. We performed a genetic test, cardiac computed tomography, and analyzed several biomarkers. We studied the association of a GRS composed of 11 genetic variants and a primary composite endpoint (cardiovascular mortality, a recurrent event, and cardiac hospitalization). RESULTS: A total of 81 patients were studied and followed up for a median of 4.1 years. There were 24 recurrent cardiovascular events. Compared with the general population, study participants had a higher prevalence of 9 out of 11 risk alleles. The GRS was significantly associated with recurrent cardiovascular events, especially when baseline low-density lipoprotein cholesterol (LDL-C) levels were elevated. Compared with the low-risk GRS tertile, the multivariate-adjusted HR for recurrences was 10.2 (95%CI, 1.1-100.3; P=.04) for the intermediate-risk group and was 20.7 (2.4-181.0; P=.006) for the high-risk group when LDL-C was≥2.8mmol/L (≥ 110mg/dL). Inclusion of the GRS improved the C-statistic (ΔC-statistic=0.086), cNRI (continuous net reclassification improvement) (30%), and the IDI (integrated discrimination improvement) index (0.05). Cardiac computed tomography frequently detected coronary calcified atherosclerosis but had limited value for prediction of recurrences. No association was observed between metalloproteinases, GRS and recurrences. CONCLUSIONS: A multilocus GRS may identify individuals at increased risk of long-term recurrences among young nondiabetic patients with AMI and improve clinical risk stratification models, particularly among patients with high baseline LDL-C levels.

The clinical evolution, imaging and laboratory studies allowed diagnosing Behçet Syndrome. The patient showed main signs as recurrent mouth ulcerations, anterior uveitis and deep vein thrombosis in the lower limbs. The clinical condition of this patient and the joint assessment of various medical specialties were the key factors in establishing the definitive diagnosis. The patient´s evolution was satisfactory treated with prednisone and anticoagulants(AU)

Deficiencia de anticuerpos específicos en pacientes pediátricos con infecciones respiratorias recurrentes / Specific antibody deficiency in pediatric patients with recurrent respiratory infections

One of the most frequent consultations in pediatric immunology corresponds to patients with recurrent respiratory infections. The most frequent clinical conditions for what they consult are recurrent viral infections, recurrent acute otitis media, recurrent sinusitis and recurrent pneumonia. Approximately 10% of patients who consult for these conditions may have a specific antibody deficiency. Specific antibody deficiency is a type of primary immunodeficiency, which is classified within the humoral deficit group, where there is a failure in the immune response for polysaccharide antigens with normal immunoglobulin levels. The diagnosis must be made since 2 years old, when the immune system acquires the ability to present a humoral response to polysaccharide antigens. In an undetermined percentage of patients, the specific antibody deficit can be resolved with the maturity of the immune system and there are patients who require prolonged treatment with antibiotic prophylaxis and gamma globulin.

Una de las consultas más frecuentes en inmunología pediátrica corresponde a pacientes con infecciones respiratorias recurrentes. Los cuadros clínicos más frecuentes por lo que consultan son infecciones virales recurrentes, otitis media aguda recurrente, sinusitis recurrente y neumonía recurrente. Aproximadamente el 10% de los pacientes que consultan por estos cuadros puede presentar una deficiencia de anticuerpos específica. La deficiencia anticuerpo específica es un tipo de inmunodeficiencia primaria, que se clasifica dentro del grupo de déficit humorales, en donde existe una falla en la respuesta inmune para antígenos polisacáridos con niveles de inmunoglobulinas normales. El diagnóstico se debe realizar después de los 2 años que es cuando el sistema inmune adquiere la capacidad de presentar respuesta humoral a antígenos polisacáridos. En un porcentaje no determinado de pacientes, el déficit de anticuerpos específicos se puede resolver con la madurez del sistema inmunológico y existen pacientes que requieren tratamiento prolongado con profilaxis antibiótica y gamaglobulina.

Inherited thrombophilia and pregnancy loss. Study of an Argentinian cohort. / Trombofilia hereditaria y pérdidas de embarazo. Estudio de una cohorte de Argentina.

BACKGROUND AND OBJECTIVES: Thrombophilia might increase the risk of suffering from obstetric complications by adversely affecting the normal placental vascular function. Our aim was to study the distributions of five thrombosis-associated genetic variants: factor V Leiden, prothrombin G20210A, -675 4G/5G PAI-1, 10034C/T gamma fibrinogen and 7872C/T factor XI and the frequencies of the deficiencies of protein C, S and antithrombin in Argentinian patients with recurrent pregnancy loss (RPL) and, therefore, to analyse their association with the risk and timing of RPL and the risk of suffering other vascular obstetric pathologies. PATIENTS AND METHODS: We performed a case-control study that included 247 patients with idiopathic RPL (cases), 107 fertile controls and 224 subjects from general population (reference group). Cases were stratified according to the gestational time of the losses (early RPL, n = 89; late losses, n = 158; foetal losses, n = 107) and according to the type of vascular obstetric pathologies. RESULTS: No differences were found in the distribution of the genetic variants among RPL group vs. control/reference group (p >.05). Similarly, no differences were observed in their distributions when analysing RPL patients stratified according to gestational times or vascular obstetric pathologies (p >.05), except for the factor V Leiden carriage in patients with foetal growth retardation vs. controls (11.8%, 4/34 vs. 1.9%, 2/107; p = .04) (OR = 7.11 [1.24-40.93], p = .03). CONCLUSIONS: Factor V Leiden might have a significant impact on certain obstetric pathologies such as foetal growth retardation. The genetic variants, 10034C/T gamma fibrinogen and 7872C/T factor XI, associated with thromboembolic disease, would not have an impact on PRE.

Recomendaciones para la orientación diagnóstica, actuación y tratamiento de crisis febriles

Las crisis febriles ocurren entre el 2-5 % de niños, entre 3 meses y 6 años y puede guardar relación con síndromes epilépticos afines. Se realizó una revisión bibliográfica sobre el tema en la base de datos Medline y se complementó con información en las bases de datos de organizaciones, de las sociedades de neurología y de guías de práctica clínica, entre otras. El objetivo de este trabajo es presentar un cuerpo de recomendaciones según grado de evidencia, útiles para reforzar y dar respuesta a algunas interrogantes y situaciones clínicas que se les presentan a los pediatras, neuropediatras y neurólogos cuando se enfrentan a niños con crisis febriles. Las recomendaciones se presentan estructuradas en base a preguntas y respuestas. Se propone un algoritmo a seguir en el servicio de urgencia y orientaciones para la familia. Se establecen criterios para la definición de las crisis en simples, complejas y recurrentes, cuáles son los factores de riesgo de recurrencia y para desarrollar epilepsia. Se abordan otros aspectos como cuáles serían los principales diagnósticos diferenciales a considerar, cómo abordar el diagnóstico, qué utilidad tendrían los exámenes complementarios y cuándo se indican, cuál sería el manejo en urgencia, criterios de internación y cuándo prescribir tratamiento profiláctico intermitente o continuo. Los profesionales que enfrentan las crisis febriles deben estar capacitados para reconocerlas y ser óptimos en su atención inicial, seguimiento y tratamiento en los servicios de urgencia, hospitalarios o consultas externas pediátricas.

Febrile seizures occur in the 2 to 5% of children, from 3 months to 6 years, and can be related to similar epileptic syndromes. The objective of this paper is to present a body of recommendations according to the degree of evidence that are useful to reinforce and answer some questions and clinical situations that are presented to pediatricians, neuropediatricians and neurologists when faced to children with febrile seizures. A bibliographic review on the subject was carried out in Medline database and it was supplemented with information of the databases of organizations, neurology societies and clinical practice guidelines, among others. The recommendations are structured based on questions and answers. An algorithm to be followed in the emergency service and orientations for the family is proposed. Criteria are established for the definition of crises in simple, complex and recurrent, which are the risk factors of recurrence and to develop epilepsy, what would be the main differential diagnoses to consider, how to approach the diagnosis, what would be the usefulness of the complementary tests and when to be indicated; what would be the management in emergency; criteria of hospitalization and when to prescribe intermittent or continuous prophylactic treatment. The professionals who attended febrile seizures must be able to recognize them and be optimal in their initial care, follow-up and treatment in the emergency, hospital or pediatric outpatient services.

Acerca de la Recurrencia Periódica Anual de Ciertos Fenómenos / About the Annual Periodic Recurrence of Certain Phenomena

Constantino Hering, uno de los médicos homeópatas más destacados del siglo XIX, fue pionero de la escuela hahnemanniana en Estados Unidos a partir de 1833, año en que se instaló en la ciudad de Filadelfia. Fue allí, precisamente, que fundó la Sociedad Hahnemanniana y la North American Academy for the Homeopathic Healing Art (Academia Estadounidense para el Arte Curativo Homeopático), considerada como la primera institución en el mundo para la enseñanza de la Homeopatía. El doctor Raúl Ibarra Ovando, egresado de la Facultad de Medicina de la Universidad Nacional Autónoma de México y especializado en Homeopatía de México, A.C., realizó la traducción (del inglés al español) del texto Acerca de la Recurrencia Periódica Anual de Ciertos Fenómenos (1853), un trabajo en el que el célebre homeópata de origen alemán trata de explicar que la recurrencia de las enfermedades se relaciona directamente con el binomio causa y efecto, dos elementos que están lejos el uno del otro y que, en algún momento, se intersectan. Hering compara varios de los fenómenos naturales con la recurrencia de las enfermedades en el ser humano, situación que, de acuerdo con sus investigaciones, no se trata de coincidencias azarosas.

(Homeopathy of Mexico), he translated (from english to spanish) the text On the Periodical Annual Recurrence of Certain Phenomena (1853), a work in which the famous german homeopath tries to explain that the recurrence of diseases is directly related to the cause and effect, understanding to this binomial as two elements that are far from each other and that, at some point, intersect. Hering compares several of the natural phenomena with the recurrence of diseases in the human being, a situation that, according to his research, is not random coincidences.(AU)

[Clinical overview of auto-inflammatory diseases]. / Panorama des maladies auto-inflammatoires.

Monogenic auto-inflammatory diseases are characterized by genetic abnormalities coding for proteins involved in innate immunity. They were initially described in mirror with auto-immune diseases because of the absence of circulating autoantibodies. Their main feature is the presence of peripheral blood inflammation in crisis without infection. The best-known auto-inflammatory diseases are mediated by interleukines that consisted in the 4 following diseases familial Mediterranean fever, cryopyrinopathies, TNFRSF1A-related intermittent fever, and mevalonate kinase deficiency. Since 10 years, many other diseases have been discovered, especially thanks to the progress in genetics. In this review, we propose the actual panorama of the main known auto-inflammatory diseases. Some of them are recurrent fevers with crisis and remission; some others evaluate more chronically; some are associated with immunodeficiency. From a physiopathological point of view, we can separate diseases mediated by interleukine-1 and diseases mediated by interferon. Then some polygenic inflammatory diseases will be shortly described: Still disease, Schnitzler syndrome, aseptic abscesses syndrome. The diagnosis of auto-inflammatory disease is largely based on anamnesis, the presence of peripheral inflammation during attacks and genetic analysis, which are more and more performant.

Peak Exercise Oxygen Uptake Predicts Recurrent Admissions in Heart Failure With Preserved Ejection Fraction.

INTRODUCTION AND OBJECTIVES: Heart failure with preserved ejection fraction (HFpEF) is a highly prevalent syndrome with an elevated risk of morbidity and mortality. To date, there is scarce evidence on the role of peak exercise oxygen uptake (peak VO2) for predicting the morbidity burden in HFpEF. We sought to evaluate the association between peak VO2 and the risk of recurrent hospitalizations in patients with HFpEF. METHODS: A total of 74 stable symptomatic patients with HFpEF underwent a cardiopulmonary exercise test between June 2012 and May 2016. A negative binomial regression method was used to determine the association between the percentage of predicted peak VO2 (pp-peak VO2) and recurrent hospitalizations. Risk estimates are reported as incidence rate ratios. RESULTS: The mean age was 72.5 ± 9.1 years, 53% were women, and all patients were in New York Heart Association functional class II to III. Mean peak VO2 and median pp-peak VO2 were 10 ± 2.8mL/min/kg and 60% (range, 47-67), respectively. During a median follow-up of 276 days [interquartile range, 153-1231], 84 all-cause hospitalizations in 31 patients (41.9%) were registered. A total of 15 (20.3%) deaths were also recorded. On multivariate analysis, accounting for mortality as a terminal event, pp-peak VO2 was independently and linearly associated with the risk of recurrent admission. Thus, and modeled as continuous, a 10% decrease of pp-peak VO2 increased the risk of recurrent hospitalizations by 32% (IRR, 1.32; 95%CI, 1.03-1.68; P = .028). CONCLUSIONS: In symptomatic elderly patients with HFpEF, pp-peak VO2 predicts all-cause recurrent admission.
