RESUMO

Introduction: Over the past decades, incidence of SLE (Systemic Lupus Erythematosus) has increased due to early case detection and improved survival of patients. SLE presents at an earlier age and has a more severe presentation in African-American, Native American, Asian, and Hispanic populations. Worldwide, lupus nephritis (LN) is observed in 29–60% of SLE patients, it has a negative impact in renal survival and patient mortality. Several cohorts have established potential risk factors associated with lupus nephritis, such as male sex, serological markers, and some extra-renal manifestations. Objectives: To describe sociodemographic, clinical, immunological, and environmental risk factors in Colombian SLE patients and to compare the population with and without nephritis, in order to establish risk factors and possible associations. Materials and methods: A total of 1175 SLE patients participated in this study. During medical care, an interview and structured survey was conducted and later registered in a database. Sociodemographic, clinical, immunological, and environmental exposure variables were analyzed. Bivariate and multivariate analyses were performed using presence of LN as an outcome. Results: Prevalence of LN was 38.7%. Variables significantly associated with LN included being male (OR 1.98), a duration of SLE>10 years (OR 1.48), positive anti-DNA (OR 1.34), positive anti-Sm (OR 1.45), and smoking (OR 1.66). Being non-smoker was a protective factor (OR 0.52). Conclusion: This study describes potential factors associated with lupus nephritis in a Latin American population. Smoking status could be a target for intervention as it is a modifiable risk factor. The association between being male and LN is observed in Latin-American populations such as presented here. Further research in other large-scale population studies and more efforts are needed to gain better insights to explicate these relationships.(AU)


Introducción: En las últimas décadas la incidencia del Lupus eritematoso sistémico (LES) se ha incrementado debido a la detección temprana y su mejoría en la supervivencia. La nefritis lúpica (NL) se observa en el 29% a 60% de los pacientes con LES, teniendo un impacto negativo en la supervivencia renal y la mortalidad. Varias cohortes han establecido factores de riesgo asociados con la NL, como el sexo masculino, marcadores serológicos y algunas manifestaciones extrarrenales. Objetivos: Describir los factores de riesgo sociodemográficos, clínicos, inmunológicos y ambientales en pacientes colombianos con LES y comparar la población con y sin NL para establecer posibles asociaciones. Materiales y métodos: Se incluyeron 1175 pacientes con LES, se analizaron variables sociodemográficas, clínicas, inmunológicas y ambientales, tomadas de bases de datos de registros cínicos. Los análisis bivariados y multivariados se realizaron utilizando la presencia de NL como desenlace. Resultados: La prevalencia de NL fue del 38,7%. Las variables significativamente asociadas con NL incluyeron sexo masculino (OR 1.98), una duración del LES>10 años (OR 1.48), anti-ADN positivo (OR 1.34), anti-Sm positivo (OR 1.45) y tabaquismo (OR 1.66), mientras que la ausencia de exposición al tabaco se comportó como factor protector (OR 0.52). Conclusión: Se describen los factores potenciales asociados con NL en una población latinoamericana. El tabaquismo se presenta como un factor de riesgo susceptible de intervención. El sexo masculino y su asociación con NL ya ha sido reportado en otras poblaciones latinoamericanas. Se requieren investigaciones a gran escala en otras poblaciones para explicar mejor estas asociaciones.(AU)

RESUMO

Resumen Introducción: El síndrome de Takotsubo es una disfunción ventricular aguda de carácter temporal, usualmente reversible, secundaria a eventos estresantes que comprometen el eje cerebro-corazón. Objetivo: describir las características clínicas, epidemiológicas y desenlaces de una cohorte de pacientes con síndrome de Takotsubo en Medellín-Colombia. Materiales y métodos: Estudio observacional, descriptivo, ambispectivo, realizado en una cohorte de pacientes. Se revisaron las historias clínicas de pacientes que ingresaron al servicio de urgencias de una institución de tercer nivel de complejidad de la ciudad de Medellín entre enero de 2011 y diciembre de 2016 con diagnóstico de síndrome de Takotsubo. Se diseñó un cuestionario para recolectar variables demográficas, clínicas, de laboratorio e imagenológicas. Se obtuvieron medidas de frecuencia y análisis estadístico con el programa SPSS versión 21. Resultados: El 66,7% de los pacientes fueron mujeres, la mortalidad fue del 11,1% y la recurrencia del 5,6%. La mayoría de los casos tuvieron un desencadenante conocido (94,5%), siendo la infección el más frecuente (44,4%). El 77,8% de los pacientes presentó disnea al ingreso y el 27,8% requirió uso de algún vasopresor. El promedio de la fracción de eyección del ventrículo izquierdo inicial fue del 34.17+7.8 con evidencia de mejoría en el control, promedio luego del control= 54,81+10.2. Discusión y conclusiones: El síndrome de Takotsubo es una condición infrecuente, las mujeres son la población más afectada y la mayoría de los casos obedece a un factor desencadenante. La mortalidad reportada está dentro de lo esperado y se evidenció un buen pronóstico a mediano plazo. MÉD.UIS. 2020;34(1):27-33.


Abstract Introduction: Takotsubo syndrome is an acute, usually reversible, temporal ventricular dysfunction secondary to stressful events that compromise the brain-heart axis. The study's objective is to describe the clinical, epidemiological characteristics and outcomes of a cohort of patients with Takotsubo syndrome in Medellin-Colombia. Methods: Observational, descriptive, ambispective study performed in a cohort of patients. We reviewed the medical records of patients who entered the emergency department of a third-level complex institution of Medellin between January 2011 and December 2016 with Takotsubo syndrome diagnosis. A questionnaire was designed to collect demographic, clinical, laboratory, and imaging variables. Frequency measures and statistical analyses were obtained with the SPSS version 21 program. Results: 66.7% of the patients were women, mortality was 11.1%, and recurrence was 5.6%. The majority of the cases had a known trigger (94.5%), being the infection the most frequent (44.4%), 77.8% of the patients presented dyspnea on admission, and 27.8% required the use of vasopressor. The mean baseline left ventricular ejection fraction was 34.17 + 7.8 with evidence of improvement in control, average after control = 54.81 + 10.2. Discussion and conclusions: Takotsubo syndrome is an uncommon condition. Women are the most affected population and most cases are due to a secondary cause. The reported mortality is within expectations, and a good medium-term cardiac prognosis was evidenced. MÉD.UIS. 2020;34(1):27-33.

RESUMO

Introducción: El lupus eritematoso sistémico (LES) es una enfermedad autoinmune caracterizada por compromiso de múltiples órganos, siendo la nefritis lúpica (NL)1 una de las manifestaciones mas graves. Objetivo: Establecer factores asociados a nefritis lúpica en los pacientes con LES. Métodos: Estudio de corte trasversal tomado de una cohorte de 1175 pacientes con LES que cumplieron criterios clasificatorios para ACR 1997 o SLICC 2012, atendidos en una IPS especializada entre 2007 y 2015. Se realizó análisis bivariado de múltiples características entre pacientes con presencia y ausencia de NL a través de chi2 para variables cuantitativas y U de Mann Whitney para variables politómicas o cuantitativas sin distribución normal en búsqueda de asociación estadística.
