Hiperuricemia asintomática y enfermedad arterial coronaria / Asymptomatic hyperuricaemia and coronary artery disease

Antecedentes: El ácido úrico se ha relacionado con la tendencia de precipitarse para formar cristales, que se presenta desde manera asintomática hasta con artritis, tofos o litiasis renal. Con anterioridad, se ha asociado la hiperuricemia asintomática a la presencia de enfermedad cardiovascular. Objetivos: Determinar la asociación de enfermedad arterial coronaria compleja en pacientes con hiperuricemia asintomática. Material y métodos: Se realizó estudio observacional, transversal, retrospectivo, unicéntrico. En un hospital de tercer nivel de México, en el periodo comprendido de junio del 2017 a marzo del 2019. Se incluyó a todos los pacientes que ingresaron para realizar angiografía coronaria; se excluyó a los pacientes con gota, uso de diuréticos y enfermedad renal crónica. Resultados: Durante el periodo del estudio se seleccionó a un total de 300 pacientes, de los cuales 40% presentaron hiperuricemia. Los pacientes con hiperuricemia eran de mayor edad (59 vs. 63; p = 0,002). El grupo de pacientes con hiperuricemia asintomática tuvo mayor proporción de lesiones coronarias complejas (64 vs. 35%; p ≤ 0,0001), así como también mayor puntuación del SYNTAX I score (27 vs. 17; p ≤ 0,001). Hubo mayor probabilidad de presentar lesiones coronarias complejas en este grupo de pacientes (OR 3,4; p ≤ 0,0001). Además, en la división por grupos de nivel de ácido úrico, se relacionaba con la presencia de lesiones coronarias complejas (Q1 = 0,5; p = 0,06); (Q2 = 2; p = 0,01) y (Q3 = 3; p ≤ 0,0001). Conclusión: Los pacientes con hiperuricemia asintomática tienen mayor riesgo de presentar lesiones coronarias complejas.(AU)

Background: Uric acid has been related to a tendency to precipitate to form crystals, presenting asymptomatically, until the formation of arthritis, tophi or renal lithiasis. Previously, the presence of asymptomatic hyperuricaemia has been associated with the presence of cardiovascular disease. Objectives: To determine the association of complex coronary artery disease in patients with asymptomatic hyperuricaemia. Material and methods: An observational retrospective, transversal, unicentric study was conducted in a tertiary hospital in Mexico, in the period from June 2017 to March 2019. All patients admitted for coronary angiography were included; patients with gout, use of diuretics and chronic kidney disease were excluded. Results: During the study period, a total of 300 patients were collected, of which 40% presented hyperuricaemia. The patients with hyperuricaemia were older (59 vs. 63, P = .002). The group of patients with asymptomatic hyperuricaemia had a higher proportion of complex coronary lesions (64 vs. 35%, P ≤ .0001) as well as a higher SYNTAX I score (27 vs. 17, P ≤ .001). There was a higher probability of presenting complex coronary lesions in this group of patients (OR 3.4, P ≤ .0001). In addition, in the group division of uric acid levels, it was related to the presence of complex coronary lesions (Q1 = .5, P = .06), (Q2 = 2, P = .01) and (Q3 = 3, P ≤ .0001). Conclusion: Asymptomatic hyperuricaemia has a higher prevalence and association of presenting complex coronary lesions.(AU)

Deformación miocárdica de la aurícula izquierda en pacientes con lupus eritematoso sistémico / Left Atrial Strain in Patients With Systemic Lupus Erythematosus

Antecedentes: En los pacientes con lupus eritematoso sistémico (LES) la disfunción diastólica del ventrículo izquierdo (DDVI) puede ser la única manifestación de involucro cardiaco anticipando una disfunción sistólica. Se ha visto que la deformación miocárdica de la aurícula izquierda (AI), mediante el strain longitudinal global de la AI (SLGAI), puede llegar a ser de utilidad en valorar la función diastólica. Objetivo: Evaluar la función de la AI mediante la deformación miocárdica en pacientes con LES. Comparar el strain de la AI en pacientes con LES activos, inactivos y controles. Métodos: Se incluyeron 50 pacientes con LES y se compararon con controles sanos pareados por edad y sexo. Se midió por ecocardiograma transtorácico la deformación miocárdica mediante el SLGAI, el strain de las 3 fases del ciclo de la AI y la tasa de strain. La diferencia entre los grupos se analizó de forma univariante. Resultados: El SLGAI en pacientes con LES fue menor que en los controles sanos (41,6% vs. 50,5%; p=0,02), así como también fue menor en las 3 fases del ciclo de la AI. No hubo diferencias en la tasa de strain en ambos grupos (LES 2,5s−1 vs. controles sanos 2,75s−1; p=0,1). También se encontró que el SLGAI fue menor en pacientes activos en comparación con controles e inactivos. Conclusiones: Los pacientes con LES tienen menor deformación miocárdica de la AI, lo que se expresa como una menor función diastólica correlacionando con daño miocárdico subclínico precoz.(AU)

Background: In patients with systemic lupus erythematosus (SLE), left ventricle diastolic dysfunction (LVDD) may be the only manifestation of cardiac involvement in anticipation of systolic dysfunction. It has been seen that myocardial deformation of the left atrium (LA), through the LA global longitudinal strain (LAGLS), may be useful in assessing diastolic function. Objective: To evaluate LA function through myocardial deformation in patients with LES, and compare the LA strain in patients with active, inactive and controls. Methods: Fifty patients with SLE were included and compared with 50 healthy controls paired by age and gender. Myocardial deformation was measured by transthoracic echocardiogram, to investigate the LAGLS, the strain of the three phases of the LA cycle and the strain rate. The differences between groups were compared in univariate analysis. Results: LAGLS in SLE patients was less than in the controls (41.6% vs. 50.5%; p=.02), and in the 3 phases of the LA cycle. There were no differences in the LA strain rate in both groups (SLE 2.5s−1 vs. controls 2.75s−1; p=.1). It was also found that the LAGLS was lesser in active patients than controls and inactive. Conclusions: SLE patients have lower myocardial deformation of the LA, which is expressed as a lower diastolic function correlating with early subclinical myocardial damage.(AU)

Recomendaciones del Colegio Mexicano de Reumatología para el manejo de las espondiloartritis / Recommendations of the Mexican College of Rheumatology for the Management of Spondyloarthritis

Objetivos: Actualizar las recomendaciones para el manejo de pacientes con espondiloartritis (EspA) en la población mexicana e identificar las variables que podrían influir en el manejo del paciente. Material y métodos: Un grupo de 15 expertos en EspA tradujo, analizó y modificó las recomendaciones del Colegio Mexicano de Reumatología (CMR) y del grupo Sociedad Internacional de Evaluación de las Espondiloartritis (ASAS)/Liga Europea contra el Reumatismo (EULAR) del 2016 a través de la revisión sistemática de la literatura realizada por dos revisores externos en el período de 2015 a 2018 utilizando los niveles de GRADE y Oxford y el porcentaje de concordancia (Delphi). Resultados: En comparación con las recomendaciones anteriores, no hubo cambios significativos desde el año 2015. Sin embargo, modificamos los 5 principios fundamentales y reducimos el número de recomendaciones a 10 por la incorporación de la primera en el texto, la combinación de 5 recomendaciones en 2 y la adición de una nueva. Confirmamos la tendencia del uso de glucocorticoides para pacientes con actividad inflamatoria y escaso acceso a productos biológicos. Se identificaron las características sociodemográficas y clínicas de los pacientes con EspA y su posible influencia en la aplicación de las recomendaciones. Conclusiones: Las 10 recomendaciones del CMR y el análisis de las características de los pacientes mexicanos con EspA se centran en el tratamiento escalonado con medios farmacológicos y no farmacológicos, fácilmente accesibles, o por el contrario sustancias de alta tecnología para un pequeño porcentaje de la población.(AU)

Objectives: To update the recommendations for the management of patients with Spondyloarthritis (SpA) in the Mexican population, and identify which variables could influence patient management. Material and methods: A group of 15 experts in SpA translated, analyzed and modified the recommendations of the Mexican College of Rheumatology (CMR) and the International Society for the Assessment of Spondyloarthritis (ASAS)/European League Against Rheumatism (EULAR) 2016 group through a systematic review of the literature by two external reviewers during the period from 2015 to 2018 using the grade of recommendation, Oxford levels of evidence, percentage of concordance (Delphi). Results: Compared to previous recommendations, there were no significant changes from the year 2015. However, we modified the five fundamental principles and reduced the number of recommendations to ten by incorporating the first item in the text and combining five recommendations into two and adding a further recommendation. We confirmed the tendency to use glucocorticoids for patients with inflammatory activity and scarce access to biologicals. We identified the sociodemographic and clinical characteristics of patients with SpA and their influence on the application of the recommendations. Conclusions: The ten recommendations of the CMR and the analysis of the characteristics of the Mexican patients with SpA focussed on step therapy, including pharmacological and non-pharmacological therapies, in a spectrum from easily accessible to high-tech substances available to a small percentage of the population.(AU)

Cytokines (IL-15, IL-21, and IFN-γ) in rheumatoid arthritis: association with positivity to autoantibodies (RF, anti-CCP, anti-MCV, and anti-PADI4) and clinical activity.

INTRODUCTION: Rheumatoid arthritis (RA) is an autoimmune disease characterized by synovial membrane damage and autoantibody production. RA is a heterogeneous disease, where cytokines such as IL-15, IL-21, and IFN-γ have been associated. However, their association with the autoantibodies has not been clearly described. The aim of this study was to evaluate the relationship between the cytokines IL-15, IL-21, and IFN-γ with the autoantibodies (RF, anti-CCP, anti-MCV, and anti-PADI4) in RA and disease activity. METHODOLOGY: This study included 153 RA patients and 80 control subjects (CS). The levels of IL-15, IL-21, IFN-γ, anti-CCP, anti-MCV, and anti-PADI4 were quantified by ELISA, whereas RF was quantified by turbidimetry. The disease activity was evaluated by the indices disease activity score 28-erythrocyte sedimentation rate (DAS28-ESR), clinical disease activity index (CDAI), and simple disease activity index (SDAI). RESULTS: The serum levels of IL-15, IL-21, and IFN-γ, and autoantibodies were increased in RA patients, compared with CS (p < 0.05). A correlation was found between IL-21 and anti-CCP and anti-MCV (p < 0.05). According to RA evolution, RF, anti-CCP, and anti-MCV had higher levels in early RA. In addition, increased levels of IL-21 were observed in RA seropositive patients (RF/anti-CCP/anti-MCV). The higher levels of both cytokines and autoantibodies were observed in moderate activity, evaluated by the three indices. CONCLUSIONS: Our results suggest that the increased soluble levels of IL-15, IL-21, and IFN-γ are involved in the inflammatory network in RA. However, IL-21 serum levels are associated with higher titers of autoantibodies (RF, anti-CCP, and anti-MCV) and IL-15 with moderate activity. Key Points • IL-15, IL-21, and IFN-y are associated with the immunopathology of RA, but not significantly with the evolution of the disease. • RF, anti-CCP, and anti-MCV had higher levels in early than established RA. • IL-21 has an association with RF, anti-CCP, and anti-MCVand, for this reason, could be proposed as a disease biomarker. • Patients with activity moderate of disease showed higher levels of RF, anti-CCP, anti-MCV, and IL-15.

Epidemiologia descriptiva de hendiduras labiopalatinas en la Clínica de Labio y Paladar Hendidos de Morelia, Michoacán, México (1989-2012) y su comparación con algunas poblaciones internacionales / Descriptive epidemiology of lip-palate fissures at the Lip and Palate Cleft Clinic in Morelia, Michoacan, Mexico (1989-2012) and a comparison with some international populations

Introducción y Objetivo. Las hendiduras labiopalatinas son malformaciones congénitas que afectan a la región maxilofacial. Su etiología es multifactorial, con factores genéticos y ambientales. Para la raza caucásica se estima una incidencia de 1:700 nacimientos, cifra que disminuye en otras poblaciones. El sexo masculino está afectado con mayor frecuencia, y solo las hendiduras palatinas aisladas presentan predominio femenino. Debido al desarrollo embriológico, el lado de mayor afectación es el izquierdo. Nuestro estudio tiene como objetivo conocer la distribución y frecuencia de las malformaciones atendidas en una institución de salud pública mexicana y su comparación con otras poblaciones internacionales. Material y Método. Llevamos a cabo un estudio observacional, descriptivo, transversal y retrospectivo, evaluando el total de expedientes clínicos de pacientes atendidos en el Servicio de Cirugía Reconstructiva Pediátrica de Morelia, Michoacan, México, durante el periodo 1989-2012. Realizamos la investigación bibliográfica en las bases de datos MEDLINE, LILACS y SciELO. Resultados. Obtuvimos un total de 800 expedientes clínicos, 460 (57.5%) de pacientes masculinos y 340 (42.5%) femeninos. La afectación de mayor frecuencia fue la hendidura labiopalatina, presente en 448 casos (56%). Esta situación se asemeja a estudios previos sobre el tema hechos en Bolivia, Sudan y México (54%). No fue posible determinar una incidencia poblacional total, ya que la institución donde realizamos el estudio atiende solo a población pediátrica. Conclusiones. La recolección de datos en nuestra institución mostro un predominio de presencia de hendidura labiopalatina en el sexo masculino, con presentación labiopalatina unilateral y del lado izquierdo. En base a ello podemos afirmar que la distribución epidemiológica de las hendiduras labiopalatinas encontrada en la Clínica de Labio y Paladar Hendidos de Morelia, Michoacan, México, se coloca en una posición intermedia al compararla con otras poblaciones internacionales (AU)

Background and Objective. The lip and palate clefts are congenital malformation that affects the maxillofacial region. Their etiology is multifactorial with such as genetics as environmental factors. For the caucuses race it´s estimated a incidence of 1:700 per births, number that decreases in other populations. The masculine sex is affected more frequently, only in the case of isolated palate cleft there’s a predominance of the feminine sex. Because of the embryologic development, the side that is more affected is the left side. The present study has as objective the knowledge of distribution and frequency of malformations treated in a Mexican public hospital and to compare with other international populations. Methods. We conduct an observational, descriptive, transverse and retrospective study, where we evaluated the total of clinic records of patients attended in the Pediatric Reconstructive Surgery Service in Morelia, Michoacan, Mexico, between 1989-2012. The bibliographic investigation was made at MEDLINE, LILACS and SciELO. Results. We got a total recruit of 800 clinical records, 460 (57.5%) male patients and 340 (42.5%) female. The most frequent affection was the combination of lip and palate with 448 (56%) cases. Situation that was similar to previous studies of Bolivia, Sudan and Mexico. It was not possible to determine the incidence because our hospital is only a pediatric institute. Conclusions. The data recollection at our center showed predominance in male patients, the most frequent malformation was unilateral lip and palate cleft and left side. We conclude that the epidemiologic distribution of the lip and palate clefts found at the Lip and Palate Cleft Clinic at Morelia, Michoacan, Mexico, is at a medium position compared with other international populations (AU)

Actualización de la Guía Mexicana para el Tratamiento Farmacológico de la Artritis Reumatoide del Colegio Mexicano de Reumatología / Update of the Mexican College of Rheumatology Guidelines for the Pharmacologic Treatment of Rheumatoid Arthritis

Antecedentes: El manejo de la artritis reumatoide ha tenido avances muy importantes en los últimos a˜nos. Las guías de práctica clínica requieren una actualización constante. Recientemente se han publicado diversas guías internacionales para el manejo farmacológico de la artritis reumatoide que difícilmente se adaptan a la realidad mexicana, en especial por la heterogénea disponibilidad de los medicamentos en las diversas instituciones del sector salud. Por ello, debido a la importancia de unificar el criterio de manejo con los tratamientos disponibles, el Colegio Mexicano de Reumatología decidió revisar las guías existentes e incorporar nueva evidencia actualizada y adaptada a la realidad del sistema de salud mexicano. Objetivo: Revisar, actualizar y adaptar la guía del manejo farmacológico de la artritis reumatoide y emitir recomendaciones adaptadas al sistema de salud de México, de acuerdo con manejos disponibles hasta diciembre de 2012. Método: Participaron en la elaboración de la guía 30 reumatólogos certificados con experiencia y juicio clínico. Las recomendaciones se basaron en niveles de evidencia de las guías de tratamiento previamente establecidas, ensayos clínicos controlados y guías estandarizadas para población adulta con artritis reumatoide. Resultados: Durante la conformación del documento, cada grupo de trabajo estableció la evidencia existente sobre los diferentes temas a tratar según su campo de mayor experiencia clínica, siendo enriquecida por la opinión de los demás expertos. Al final, toda la evidencia y las decisiones tomadas se unificaron en un manuscrito, se desarrolló un algoritmo de tratamiento y se resumieron en tablas estandarizadas por medicamento. onclusiones: La actualización de la Guía Mexicana para el Tratamiento Farmacológico de la Artritis Reumatoide integra la mejor información disponible para la toma de decisiones y contextualiza su empleo al complejo y heterogéneo sistema de salud mexicano (AU)

Background: The pharmacologic management of rheumatoid arthritis has progressed substantially over the past years. It is therefore desirable that existing information be periodically updated. There are several published international guidelines for the treatment of rheumatoid arthritis that hardly adapt to the Mexican health system because of its limited healthcare resources. Hence, it is imperative to unify the existing recommendations and to incorporate them to a set of clinical, updated recommendations;the Mexican College of Rheumatology developed these recommendations in order to offer an integral management approach of rheumatoid arthritis according to the resources of the Mexican health system. Objective: To review, update and improve the available evidence within clinical practice guidelines on the pharmacological management of rheumatoid arthritis and produce a set of recommendations adapted to the Mexican health system, according to evidence available through December 2012. Methods: The working group was composed of 30 trained and experienced rheumatologists with a high quality of clinical knowledge and judgment. Recommendations were based on the highest quality evidence from the previously established treatment guidelines, meta-analysis and controlled clinical trials for the adult population with rheumatoid arthritis. Results: During the conformation of this document, each working group settled the existing evidence from he different topics according to their experience. Finally, all the evidence and decisions were unified into a single document, treatment algorithm and drug standardization tables. Conclusions: This update of the Mexican Guidelines for the Pharmacologic Treatment of Rheumatoid Arthritis provides the highest quality information available at the time the working group undertook this review and contextualizes its use for the complex Mexican health system (AU)

Depression and its correlation with in patients pain in the rheumatology service of a Mexican teaching hospital.

The depressive symptoms are associated with chronic pain in this study. A cross-sectional study was performed. A visual analog scale was used to register pain intensity. Depressive symptoms were measured using the Center of Epidemiological Studies (CES-Dr) scale as modified by Eaton and reviewed for use in the Mexican population. The study included 245 patients, with a mean age of 46 years, 86.1% of whom were female. The prevalence of some degree of depression was 55.1%. Patients with fibromyalgia had the highest prevalence of symptoms of depression (78.38%) and major depression (29.73%). Stepwise multiple regressions indicated that the best model (r2 = 0.26) to predict the CES-Dr score included the global pain score (P < 0.0001) and education level (P < 0.004). The Cronbach's alpha of the CES-Dr was high (alpha = 0.888). There was moderate correlation (r = 0.442), P < 0.0001 of the CES-Dr numeric score with the intensity of global pain.
