Outcome of patients with autoimmune diseases in the intensive care unit. A mixed cluster analysis.

Antecedentes: El interés en las enfermedades autoinmunes (EA) y su desenlace en la unidad de cuidado intensivo (UCI) han incrementado debido al reto clínico que suponen para el diagnóstico y manejo, debido a que la mortalidad en UCI fluctúa entre el 17 – 55 %. El siguiente trabajo representa la experiencia de un año de nuestro grupo en un hospital de tercer nivel. Objetivo: Identificar factores asociados a mortalidad particulares de los pacientes con enfermedades autoinmunes que ingresan a una UCI, de un hospital de tercer nivel en Bogotá, Colombia. Métodos: El uso de análisis de componentes principales basado en el método descriptivo multivariado y análisis de múltiple correspondencia fue realizado para agrupar varias variables relacionadas con asociación significativa y contexto clínico común. Resultados: Cincuenta pacientes adultos con EA con una edad promedio de 46,7 ± 17,55 años fueron evaluados. Los dos diagnósticos más comunes fueron lupus eritematoso sistémico y esclerosis sistémica, con una frecuencia de 45% y 20% de los pacientes respectivamente. La principal causa de admisión en la UCI fue la infección seguido de actividad aguda de la EA, 36% y 24% respectivamente. La mortalidad durante la estancia en UCI fue del 24%. El tiempo de hospitalización antes de la admisión a la UCI, el choque, soporte vasopresor, ventilación mecánica, sepsis abdominal, Glasgow bajo y plasmaféresis fueron factores asociados con mortalidad. Dos fenotipos de variables fueron definidos relacionadas con tiempo en la UCI y medidas de soporte en UCI, las cuales fueron asociadas supervivencia y mortalidad. Conclusiones: La identificación de factores individuales y grupos de factores por medio del análisis de componentes principales permitirá la implementación de medidas terapéutica de manera temprana y agresiva en pacientes con EA en la UCI para evitar desenlaces fatales.Objective: The interest on autoimmune diseases (ADs) and their outcome at the intensive care unit (ICU) has increased due to the clinical challenge for diagnosis and management, due to mortality that range between 17- 55%. The current work presents a-year experience on factors related with mortality of patients with Ads in a tertiary hospital. Methods: The mixed-cluster methodology based on multivariate descriptive methods such as principal component analysis and multiple correspondence analyses was performed to summarize sets of related variables with strong associations and common clinical context. Results: Fifty adult patients with ADs with a mean age of 46.7 ± 17.55 years were assessed. The two most common diagnoses were systemic lupus erythematosus and systemic sclerosis, registered in 45% and 20% of patients, respectively. The main causes of admission to ICU were infection and AD flare up, observed in 36% and 24%, respectively. Mortality during ICU stay was 24%. The length of hospital stay before ICU admission, shock, vasopressors, mechanical ventilation, abdominal sepsis, Glasgow score and plasmapheresis were all factors associated with mortality. Two new clinical clusters variables (NCVs) were defined: Time ICU and ICU Support Profile, which were associated with survivor and no survivor variables. Conclusion: There is still a high morbidity and mortality in patients with ADs seen at the ICU. Identification of single factors and groups of factors from NCVs will allow implementation of early and aggressive therapies in patients with ADs at the ICU in order to avoid fatal outcomes

Resultados Se identificaron 248.995 casos, lo que permite calcular una prevalencia en mayores de 18 años del 0,52%, de los cuales el 80,7% son mujeres, con una relación mujer:hombre de 4,2:1, con mayor prevalencia entre el grupo etario de 70 a 74 años. Los departamentos con mayor número de casos son Bogotá D.C. (64.121), seguido de Antioquia (43.771); sin embargo, los departamentos con mayor prevalencia fueron Cesar (1,13%), Casanare (0,96%) y Risaralda (0,93%). Conclusiones Se presenta información demográfica y epidemiológica de artritis reumatoide en Colombia. Se documentó una prevalencia concordante con datos de la región, similar a Brasil (0,46%), Venezuela (0,4%) y Perú (0,55%), menor que Argentina (0,94%) y México (1,6%).Q4Artículo original83-87Objective To estimate the prevalence and describe the main demographic characteristics of rheumatoid arthritis in adults in Colombia. Material and methods A descriptive cross-sectional study was conducted using the data taken from the Integral Information System of Social Protection of the Ministry of Health during the years 2012–2016. Results A total of 248,995 cases were identified, which gave an estimated prevalence of 0.52% in those older than 18 years of age. The large majority (80.7% were women, with a female:male ratio of 4.2:1, and there was a higher prevalence in the 70–74 years age group. The departments with the highest number of cases were Bogota DC (64,121), followed by Antioquia (43,771), but the departments with the highest prevalence were Cesar (1.13%), Casanare (0.96%), and Risaralda (0.93%). Conclusions Demographic and epidemiological information on rheumatoid arthritis in Colombia is presented. A similar prevalence is reported in other studies from the region, like Brazil (0.46%), Venezuela (0.4%), or Peru (0.55%), but lower than Argentina (0.94%) or Mexico (1.6%)

Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality

All-cause mortality in the cohorts of the Spanish AIDS Research Network (RIS) compared with the general population: 1997Ł2010

Abstract Background: Combination antiretroviral therapy (cART) has produced significant changes in mortality of HIVinfected persons. Our objective was to estimate mortality rates, standardized mortality ratios and excess mortality rates of cohorts of the AIDS Research Network (RIS) (CoRIS-MD and CoRIS) compared to the general population. Methods: We analysed data of CoRIS-MD and CoRIS cohorts from 1997 to 2010. We calculated: (i) all-cause mortality rates, (ii) standardized mortality ratio (SMR) and (iii) excess mortality rates for both cohort for 100 personyears (py) of follow-up, comparing all-cause mortality with that of the general population of similar age and gender. Results: Between 1997 and 2010, 8,214 HIV positive subjects were included, 2,453 (29.9%) in CoRIS-MD and 5,761 (70.1%) in CoRIS and 294 deaths were registered. All-cause mortality rate was 1.02 (95% CI 0.91-1.15) per 100 py, SMR was 6.8 (95% CI 5.9-7.9) and excess mortality rate was 0.8 (95% CI 0.7-0.9) per 100 py. Mortality was higher in patients with AIDS, hepatitis C virus (HCV) co-infection, and those from CoRIS-MD cohort (1997. Conclusion: Mortality among HIV-positive persons remains higher than that of the general population of similar age and sex, with significant differences depending on the history of AIDS or HCV coinfection

Spatiotemporal Characteristics of the Largest HIV-1 CRF02_AG Outbreak in Spain: Evidence for Onward Transmissions

Background and Aim: The circulating recombinant form 02_AG (CRF02_AG) is the predominant clade among the human immunodeficiency virus type-1 (HIV-1) non-Bs with a prevalence of 5.97% (95% Confidence Interval-CI: 5.41–6.57%) across Spain. Our aim was to estimate the levels of regional clustering for CRF02_AG and the spatiotemporal characteristics of the largest CRF02_AG subepidemic in Spain.Methods: We studied 396 CRF02_AG sequences obtained from HIV-1 diagnosed patients during 2000–2014 from 10 autonomous communities of Spain. Phylogenetic analysis was performed on the 391 CRF02_AG sequences along with all globally sampled CRF02_AG sequences (N = 3,302) as references. Phylodynamic and phylogeographic analysis was performed to the largest CRF02_AG monophyletic cluster by a Bayesian method in BEAST v1.8.0 and by reconstructing ancestral states using the criterion of parsimony in Mesquite v3.4, respectively.Results: The HIV-1 CRF02_AG prevalence differed across Spanish autonomous communities we sampled from (p < 0.001). Phylogenetic analysis revealed that 52.7% of the CRF02_AG sequences formed 56 monophyletic clusters, with a range of 2–79 sequences. The CRF02_AG regional dispersal differed across Spain (p = 0.003), as suggested by monophyletic clustering. For the largest monophyletic cluster (subepidemic) (N = 79), 49.4% of the clustered sequences originated from Madrid, while most sequences (51.9%) had been obtained from men having sex with men (MSM). Molecular clock analysis suggested that the origin (tMRCA) of the CRF02_AG subepidemic was in 2002 (median estimate; 95% Highest Posterior Density-HPD interval: 1999–2004). Additionally, we found significant clustering within the CRF02_AG subepidemic according to the ethnic origin.Conclusion: CRF02_AG has been introduced as a result of multiple introductions in Spain, following regional dispersal in several cases. We showed that CRF02_AG transmissions were mostly due to regional dispersal in Spain. The hot-spot for the largest CRF02_AG regional subepidemic in Spain was in Madrid associated with MSM transmission risk group. The existence of subepidemics suggest that several spillovers occurred from Madrid to other areas. CRF02_AG sequences from Hispanics were clustered in a separate subclade suggesting no linkage between the local and Hispanic subepidemics

Dressler’s syndrome : the return of a forgotten entity

El síndrome de Dressler es una enfermedad infrecuente que fue descrita por primera vez en 1956 por el doctor William Dressler. Corresponde a un cuadro de pericarditis secundaria, en ocasiones asociada a efusión pericárdica de aparente etiología autoinmunitaria, que hace parte de los síndromes de lesión poscardiaca. Se presenta un caso de síndrome de Dressler en un paciente joven.Q4Dressler’s syndrome is a rare entity which was first described in 1956 by Dr. William Dressler. It consists of secondary peri carditis, at times associated with pericardial effusion with an apparently autoimmune etiology, which is one of the post-cardiac injury syndromes. We present a case of Dressler’s syndrome in a young patient.Revista Nacional - IndexadaS

Prevalence of systemic sclerosis in Colombia : data from the National Health Registry 2012-2016

Q1Introduction: Systemic sclerosis is an autoimmune disease that characteristically presents with fibrosis and vasculopathy. In Latin America, the information on the epidemiology of this disease is scarce and records are essential to know its behavior in the populations. In Colombia, the Ministry of Health uses the SISPRO tool to collect information on the unified national health system which offers nearly universal coverage (around 95%). This public information makes it possible to perform epidemiological studies on different diseases. Objectives: Using the SISPRO data corresponding to the years 2012–2016, we analyzed the prevalence and characteristics of patients with systemic sclerosis. Methods: A descriptive cross-sectional study was performed based on the SISPRO data; we used as keywords the diagnoses of the International Classification of Diseases related to the diagnosis of systemic sclerosis. Results: A total of 11,300 individuals diagnosed with systemic sclerosis were documented. The estimated prevalence was 23.7 cases per 100,000 inhabitants (based on a total population of 47,663,162); this disease is more frequent in the age group of 65–69 years in females (77%), and has a female:male ratio of 3.27:1. Conclusion: This study describes the epidemiological characteristics of systemic sclerosis in Colombia, based on official statistics from the Ministry of Health. The results provide a new vision of this disease in Latin America and open the door to future research, in order to better understand the particular characteristics of this disease in our country and our region.https://orcid.org/0000-0002-7010-8338https://orcid.org/0000-0003-0960-9480Revista Internacional - Indexad

Prevalence of inflammatory myopathies in Colombia: Demographic analysis from the National Health Registry 2012–2018

Introducción Utilizando datos del Ministerio de Salud de Colombia, realizamos un análisis de prevalencia y características demográficas generales de pacientes con miopatías inflamatorias, con datos del 2012 al 2018. Materiales y métodos Estudio descriptivo transversal basado en datos del Ministerio de Salud de Colombia. Utilizamos como términos clave los códigos diagnósticos del Manual Internacional de Enfermedades relacionados con el diagnóstico de miopatías inflamatorias. Resultados Se encontraron 12.401 individuos con diagnóstico de miopatía inflamatoria y se estimó una prevalencia global de 25,7 casos por 100.000 habitantes. Este diagnóstico es más frecuente en el grupo de edad de 65 a 69 años y en la población femenina (64%), con una relación mujer:hombre de 1,79:1. Además, calculamos una prevalencia de 15,1 casos por 100.000 habitantes para dermatomiositis y 7,3 casos por 100.000 habitantes para polimiositis (sobre una población total de 48.203). Existe poca información sobre la epidemiología de las miopatías en América Latina, y los registros son fundamentales para conocer su comportamiento en las poblaciones. En Colombia, el Ministerio de Salud recopila información del sistema de salud, que tiene una cobertura casi universal (alrededor del 95%). Esta información permite realizar estudios epidemiológicos sobre diferentes enfermedades. Para el presente estudio analizamos los datos disponibles sobre miopatías inflamatorias en Colombia. Conclusiones El presente trabajo describe por primera vez las características demográficas de las miopatías inflamatorias en la población colombiana con base en datos oficiales del Ministerio de Salud, donde la más frecuente fue la dermatomiositis y se evidenció un predominio en la población femenina.Introduction Using data from the Ministry of Health of Colombia, we performed an analysis of prevalence and general demographic characteristics of patients with inflammatory myopathies, with data from 2012 to 2018. Materials and methods A descriptive cross-sectional study based on data from the Ministry of Health of Colombia. We used as key terms the diagnostic codes of the International Manual of Diseases related to the diagnosis of inflammatory myopathies. Results We founded 12,401 individuals with a diagnosis of inflammatory myopathy and estimated an overall prevalence of 25.7 cases per 100,000 inhabitants. This diagnosis is more common in the age group of 65–69 years, and in the female population (64%), with a female-to-male ratio 1.79:1. In addition, we calculated a prevalence of 15.1 cases per 100,000 inhabitants for dermatomyositis and 7.3 cases per 100,000 inhabitants for polymyositis (based on a total population of 48,203). There is little information on the epidemiology of myopathies in Latin America, and records are essential to know their behaviour in populations. In Colombia, the Ministry of Health collects information from the health system, which has nearly universal coverage (around 95%). This information makes it possible to carry out epidemiological studies on different diseases. For the present study we analysed the available data on inflammatory myopathies in Colombia. Conclusions The present work describes for the first time the demographic characteristics of inflammatory myopathies in the Colombian population based on official data from the Ministry of Health, where the most frequent was dermatomyositis and a predominance in the female population was evidenced.Revista Nacional - IndexadaS
