ABSTRACT

Introducción: La identificación de los fenotipos clínicos son claves en la modulación de la expresión clínica, para un tratamiento integrado de la EPOC. Objetivos: Caracterizar los fenotipos clínicos de la EPOC en los pacientes atendidos en el Hospital Neumológico Benéfico Jurídico. Métodos:Se realizó un estudio observacional descriptivo retrospectivo, en 172 pacientes con diagnóstico de EPOC, en el Hospital Neumológico Benéfico Jurídico durante el año 2017.Resultados: El 38,4 % de los pacientes tenían edad entre 70-79 años. Del total de pacientes, el 54,6 % eran del sexo masculino. El 52,9 % eran fumadores activos y el 41,3 % exfumadores. Aunque las diferencias no fueron significativas, la edad avanzada y el sexo masculino fueron más frecuentes en el fenotipo enfisematoso agudizador y agudizador bronquítico crónico. El tabaquismo activo fue más frecuente en el fenotipo enfisematoso agudizador. Todos los pacientes con el fenotipo agudizador bronquítico crónico tuvieron dos o más exacerbaciones, mientras que el enfisematoso agudizador se relacionó con una severidad grave de la EPOC (46,7 %). Conclusiones: El sexo masculino y la edad avanzada muestran una tendencia a relacionarse con el fenotipo enfisematoso agudizador y agudizador bronquítico crónico, mientras que el tabaquismo activo es más frecuente en el fenotipo enfisematoso agudizador. El fenotipo agudizador bronquítico crónico se relaciona con mayores exacerbaciones y el enfisematoso agudizador con una mayor severidad de la EPOC.


Introduction: The identification of clinical phenotypes are key in the modulation of clinical expression, for an integrated treatment of COPD. Objectives: To characterize the clinical phenotypes of COPD in patients treated at the Hospital Neumológico Benéfico Jurídico. Methods: A retrospective descriptive observational study was carried out in 172 patients with a diagnosis of COPD at the Hospital Neumológico Benéfico Jurídico in 2017. Results: 38.4 % of the patients were between 70-79 years of age. Of the total number of patients, 54.6 % were male. 52.9 % were active smokers and 41.3 % ex-smokers. Although the differences were not significant, advanced age and male sex were more frequent in the exacerbator emphysematous and chronic bronchial exacerbator phenotype. Active smoking was more frequent in the exacerbating emphysematous phenotype. All patients with the chronic bronchial exacerbator phenotype had two or more exacerbations, while exacerbation emphysematous was associated with severe severity of COPD (46.7 %). Conclusions: Male sex and advanced age show a tendency to be related to the exacerbating emphysematous phenotype and chronic bronchitis exacerbator, while active smoking is more frequent in the exacerbating emphysematous phenotype. The chronic bronchitis exacerbator phenotype is related to greater exacerbations and exacerbation emphysematous with a greater severity of COPD

ABSTRACT

Introducción: La enfermedad pulmonar obstructiva crónica es un problema sanitario mundial por su elevada prevalencia, morbilidad y cuantioso costo económico. Objetivo: Caracterizar mediante la pletismografía a los pacientes con diagnóstico de enfermedad pulmonar obstructiva crónica que presentaron una discrepancia clínica espirométrica. Métodos: Se realizó un estudio descriptivo y transversal en 33 pacientes con diagnóstico de enfermedad pulmonar obstructiva crónica que acudieron a consulta externa del Hospital Neumológico Benéfico Jurídico y el Centro de Investigaciones Clínicas. Se les realizaron volúmenes pulmonares por pletismografía corporal y espirometría en el período comprendido de noviembre 2016 a marzo 2018. Resultados: El sexo masculino (69,7 por ciento) resultó el más frecuente y el grupo de edad predominante fue mayor de 65 años (60,6 por ciento). El 41,2 por ciento de los pacientes presentaron grado de obstrucción moderadamente severo. La capacidad pulmonar total y el volumen residual fueron normales (72,7 por ciento y 42,5 por ciento) respectivamente. El 43,8 por ciento de los pacientes presentaron hiperinsuflación leve. El grado 3 de disnea fue el que predominó en los pacientes. El 12,1 por ciento de los pacientes presentaron aumento del volumen residual dado por atrapamiento aéreo grave con la disminución del volumen espiratorio forzado en el primer segundo. Conclusiones: El comportamiento de los volúmenes pulmonares por pletismografía corporal en la enfermedad pulmonar obstructiva crónica con disociación clínico-espirométrica, evidenció la disminución del volumen espiratorio forzado en el primer segundo y el aumento del volumen residual relacionándose con el grado de disnea(AU)


Introduction: Chronic obstructive pulmonary disease is a global health problem due to its high prevalence, morbidity and high economic cost. Objective: By using plethysmography, to describe patients with diagnosis of chronic obstructive pulmonary disease that had spirometric clinical discrepancy. Methods: A descriptive and cross-sectional study was carried out in 33 patients with diagnosis of chronic obstructive pulmonary disease who attended the outpatient clinic at Benéfico Jurídico Pneumologic Hospital and the Clinical Research Centre. Lung volumes were performed by body plethysmography and spirometry from November 2016 to March 2018. Results: The male sex (69.7 percent) was the most frequent and the predominant age group was older than 65 years (60.6 percent). 41.2 percent of the patients had moderately severe degree of obstruction. Total lung capacity and residual volume were normal, 72.7 percent and 42.5 percent, respectively. 43.8 percent of the patients had mild hyperinflation. Grade 3 dyspnea was the one that predominated in the patients. 12.1 percent of the patients showed increased residual volume due to severe air trapping with decreased forced expiratory volume in the first second. Conclusions: The behavior of lung volumes by body plethysmography in chronic obstructive pulmonary disease with clinical-spirometric dissociation, evidenced decrease in forced expiratory volume in the first second and increased in residual volume related to the degree of dyspnea(AU)

ABSTRACT

BACKGROUND@#Chronic obstructive pulmonary disease (COPD) is a common public health problem worldwide. Recent studies have reported that socioeconomic status (SES) is related to the incidence of COPD. This study aimed to investigate the association between SES and COPD among adults in Jiangsu province, China, and to determine the possible direct and indirect effects of SES on the morbidity of COPD.@*METHODS@#A cross-sectional study was conducted among adults aged 40 years and above between May and December of 2015 in Jiangsu province, China. Participants were selected using a multistage sampling approach. COPD, the outcome variable, was diagnosed by physicians based on spirometry, respiratory symptoms, and risk factors. Education, occupation, and monthly family average income (FAI) were used to separately indicate SES as the explanatory variable. Mixed-effects logistic regression models were introduced to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for examining the SES-COPD relationship. A pathway analysis was conducted to further explore the pulmonary function impairment of patients with different SES.@*RESULTS@#The mean age of the 2421 participants was 56.63 ± 9.62 years. The prevalence of COPD was 11.8% (95% CI: 10.5%-13.1%) among the overall sample population. After adjustment for age, gender, residence, outdoor and indoor air pollution, body weight status, cigarette smoking, and potential study area-level clustering effects, educational attainment was negatively associated with COPD prevalence in men; white collars were at lower risk (OR: 0.60, 95% CI: 0.43-0.83) of experiencing COPD than blue collars; compared with those within the lower FAI subgroup, participants in the upper (OR: 0.68, 95% CI: 0.49-0.97) tertiles were less likely to experience COPD. Such negative associations between all these three SES indicators and COPD were significant among men only. Education, FAI, and occupation had direct or indirect effects on pulmonary function including post-bronchodilator forced expiratory volume in 1 s/forced vital capacity (FEV1/FVC), FEV1, FVC, and FEV1 percentage of predicted. Education, FAI, and occupation had indirect effects on pulmonary function indices of all participants mainly through smoking status, indoor air pollution, and outdoor air pollution. We also found that occupation could affect post-bronchodilator FEV1/FVC through body mass index.@*CONCLUSIONS@#Education, occupation, and FAI had an adverse relationship with COPD prevalence in Jiangsu province, China. SES has both direct and indirect associations with pulmonary function impairment. SES is of great significance for COPD morbidity. It is important that population-based COPD prevention strategies should be tailored for people with different SES.

ABSTRACT

ABSTRACT Objective: The identification of persistent airway obstruction is key to making a diagnosis of COPD. The GOLD guidelines suggest a fixed criterion-a post-bronchodilator FEV1/FVC ratio < 70%-to define obstruction, although other guidelines suggest that a post-bronchodilator FEV1/FVC ratio < the lower limit of normal (LLN) is the most accurate criterion. Methods: This was an observational study of individuals ≥ 40 years of age with risk factors for COPD who were referred to our pulmonary function laboratory for spirometry. Respiratory symptoms were also recorded. We calculated the prevalence of airway obstruction and of no airway obstruction, according to the GOLD criterion (GOLD+ and GOLD−, respectively) and according to the LLN criterion (LLN+ and LLN−, respectively). We also evaluated the level of agreement between the two criteria. Results: A total of 241 individuals were included. Airway obstruction was identified according to the GOLD criterion in 42 individuals (17.4%) and according to the LLN criterion in 23 (9.5%). The overall level of agreement between the two criteria was good (k = 0.67; 95% CI: 0.52-0.81), although it was lower among the individuals ≥ 70 years of age (k = 0.42; 95% CI: 0.12-0.72). The proportion of obese individuals was lower in the GOLD+/LLN+ category than in the GOLD+/LLN− category (p = 0.03), as was the median DLCO (p = 0.04). Conclusions: The use of the GOLD criterion appears to be associated with a higher prevalence of COPD. The agreement between the GOLD and LLN criteria also appears to be good, albeit weaker in older individuals. The use of different criteria to define airway obstruction seems to identify individuals with different characteristics. It is essential to understand the clinical meaning of discordance between such criteria. Until more data are available, we recommend a holistic, individualized approach to, as well as close follow-up of, patients with discordant results for airway obstruction.


RESUMO Objetivo: A identificação de obstrução persistente das vias aéreas é fundamental para o diagnóstico de DPOC. As diretrizes da GOLD sugerem um critério fixo - relação VEF1/CVF pós-broncodilatador < 70% - para definir obstrução, embora outras diretrizes sugiram que a relação VEF1/CVF pós-broncodilatador < o limite inferior da normalidade (LIN) é o critério mais preciso. Métodos: Estudo observacional com indivíduos ≥ 40 anos de idade com fatores de risco para DPOC encaminhados ao nosso laboratório de função pulmonar para espirometria. Também foram registrados sintomas respiratórios. Calculamos a prevalência de obstrução e de ausência de obstrução das vias aéreas segundo o critério GOLD (GOLD+ e GOLD−, respectivamente) e segundo o critério LIN (LIN+ e LIN−, respectivamente). Avaliamos também o grau de concordância entre os dois critérios. Resultados: Foram incluídos 241 indivíduos. Obstrução das vias aéreas foi identificada segundo o critério GOLD em 42 indivíduos (17,4%) e segundo o critério LIN em 23 (9,5%). A concordância global entre os dois critérios foi boa (k = 0,67; IC95%: 0,52-0,81), embora tenha sido menor entre os indivíduos ≥ 70 anos de idade (k = 0,42; IC95%: 0,12-0,72). A proporção de obesos foi menor na categoria GOLD+/LIN+ do que na categoria GOLD+/LIN− (p = 0,03), assim como a mediana de DLCO (p = 0,04). Conclusões: A utilização do critério GOLD parece estar associada a uma maior prevalência de DPOC. A concordância entre os critérios GOLD e LIN também parece ser boa, embora seja mais fraca em indivíduos mais velhos. A utilização de diferentes critérios para definir obstrução das vias aéreas parece identificar indivíduos com diferentes características. É essencial compreender o significado clínico da discordância entre esses critérios. Até que mais dados estejam disponíveis, recomendamos uma abordagem holística e individualizada e também um acompanhamento cuidadoso dos pacientes com resultados discordantes para obstrução das vias aéreas.

ABSTRACT

ABSTRACT Objective: To evaluate the frequency of asthma-COPD overlap (ACO) in patients with COPD and to compare, from a clinical, laboratory, and functional point of view, patients with and without ACO, according to different diagnostic criteria. Methods: The participants underwent evaluation by a pulmonologist, together with spirometry and blood tests. All of the patients were instructed to record their PEF twice a day. The diagnosis of ACO was based on the Proyecto Latinoamericano de Investigación en Obstrucción Pulmonar (PLATINO, Latin American Project for the Investigation of Obstructive Lung Disease) criteria, the American Thoracic Society (ATS) Roundtable criteria, and the Spanish criteria. We investigated patient histories of exacerbations and hospitalizations, after which we applied the COPD Assessment Test and the modified Medical Research Council scale, to classify risk and symptoms in accordance with the GOLD criteria. Results: Of the 51 COPD patients, 14 (27.5%), 8 (12.2%), and 18 (40.0) were diagnosed with ACO on the basis of the PLATINO, ATS Roundtable, and Spanish criteria, respectively. The values for pre-bronchodilator FVC, post-bronchodilator FVC, and pre-bronchodilator FEV1 were significantly lower among the patients with ACO than among those with COPD only (1.9 ± 0.4 L vs. 2.4 ± 0.7 L, 2.1 ± 0.5 L vs. 2.5 ± 0.8 L, and 1.0 ± 0.3 L vs. 1.3 ± 0.5 L, respectively). When the Spanish criteria were applied, IgE levels were significantly higher among the patients with ACO than among those with COPD only (363.7 ± 525.9 kU/L vs. 58.2 ± 81.6 kU/L). A history of asthma was more common among the patients with ACO (p < 0.001 for all criteria). Conclusions: In our sample, patients with ACO were more likely to report previous episodes of asthma and had worse lung function than did those with COPD only. The ATS Roundtable criteria appear to be the most judicious, although concordance was greatest between the PLATINO and the Spanish criteria.


RESUMO Objetivo: Avaliar a frequência de asthma-COPD overlap (ACO, sobreposição asma-DPOC) em pacientes com DPOC e comparar, do ponto de vista clínico, laboratorial e funcional, os pacientes com e sem essa sobreposição conforme diferentes critérios diagnósticos. Métodos: Os participantes foram submetidos à avaliação com pneumologista, espirometria e exame sanguíneo, sendo orientados a manter o registro do PFE duas vezes ao dia. O diagnóstico de ACO deu-se através dos critérios Projeto Latino-Americano de Investigação em Obstrução Pulmonar (PLATINO), American Thoracic Society (ATS) Roundtable e Espanhol. Foram investigados os históricos de exacerbações e hospitalizações e aplicados os instrumentos COPD Assessment Test e escala Medical Research Council modificada, utilizados para a classificação de risco e sintomas da GOLD. Resultados: Entre os 51 pacientes com DPOC, 14 (27,5%), 8 (12,2%) e 18 (40,0) foram diagnosticados com ACO segundo os critérios PLATINO, ATS Roundtable e Espanhol, respectivamente. Pacientes com sobreposição significativamente apresentaram pior CVF pré-broncodilatador (1,9 ± 0,4 L vs. 2,4 ± 0,7 L), CVF pós-broncodilatador (2,1 ± 0,5 L vs. 2,5 ± 0,8 L) e VEF1 pré-broncodilatador (1,0 ± 0,3 L vs. 1,3 ± 0,5 L) quando comparados a pacientes com DPOC. Os níveis de IgE foram significativamente mais elevados em pacientes com sobreposição diagnosticados pelo critério Espanhol (363,7 ± 525,9 kU/L vs. 58,2 ± 81,6 kU/L). O histórico de asma foi mais frequente em pacientes com a sobreposição (p < 0,001 para todos os critérios). Conclusões: Nesta amostra, pacientes com ACO relataram asma prévia com maior frequência e possuíam pior função pulmonar quando comparados a pacientes com DPOC. O critério ATS Roundtable aparenta ser o mais criterioso em sua definição, enquanto os critérios PLATINO e Espanhol apresentaram maior concordância entre si.

ABSTRACT

Abstract Chronic Obstructive Pulmonary Disease (COPD) is among the leading causes of morbidity and mortality in developing countries; however, few systematic reviews are available in the literature. This review examines the prevalence of COPD in the Brazilian population. For this purpose, a systematic review and meta-analysis was conducted of epidemiological observational studies indexed in the databases PubMed, Cochrane, Ovid, Scopus, ScienceDirect, SciELO, Lilacs, and Google Scholar published up to May 2018. The prevalence was estimated using a random effects model. Of the 1,182 articles identified, 12 were eligible. The prevalence of COPD in Brazil was 17% (95%CI: 13-22; I2 = 94%) and the region with the highest prevalence of COPD was the Center-western region (25%), followed by the Southeastern region (23%). The Southern region had the lowest prevalence among the studies (12%). We found that Brazil has a high occurrence of COPD, higher than the estimates of Latin American and world population Hence, additional studies are necessary to support intervention strategies, as well as formulation of specific public health policies to control and prevent COPD.


Resumo A Doença Pulmonar Obstrutiva Crônica (DPOC) encontra-se entre as principais causas de morbidade e mortalidade em países em desenvolvimento, contudo, poucos estudos de revisão sistemática estão disponíveis na literatura. Neste sentido, sumarizamos a prevalência de DPOC na população brasileira. Para tanto, foi realizada revisão sistemática e metanálise de estudos epidemiológicos observacionais indexados nas bases de dados PubMed, Cochrane, Ovid, Scopus, ScienceDirect, SciELO, Lilacs, Google Scholar, publicados até maio de 2018. As prevalências foram estimadas utilizando modelo de efeitos aleatórios. Identificaram-se 1.182 e 12 artigos foram elegíveis. A prevalência de DPOC no Brasil foi de 17% (IC95%: 13-22; I2 = 94%) entre adultos maiores de 40 anos e a região de maior prevalência de DPOC é o Centro-Oeste (25%), seguida pela Região Sudeste (23%). A Região Sul registrou a menor prevalência entre os estudos (12%). Conclui-se que o Brasil apresenta elevada ocorrência de DPOC. Desta forma, estudos adicionais são necessários para subsidiar estratégias de intervenção, bem como formulação de políticas públicas de saúde especificas voltadas ao controle e prevenção da DPOC.

ABSTRACT

Abstract Introduction: Chronic obstructive pulmonary disease (COPD) is the most prevalent respiratory problem in the world. Patients with human immunodeficiency virus (HIV) infection have a higher prevalence of smoking and recurrent lung infections and are at higher risk of COPD. Objective: To determine the prevalence of COPD in HIV-diagnosed patients referred to an infectious diseases hospital. Method: Individuals with HIV infection without previous or ongoing antiretroviral treatment, with chronic respiratory symptoms, with or without a history of exposure for the development of COPD were included. Pre- and post-bronchodilation spirometry, high-resolution computed tomography, viral load determination and CD4 count were carried out. Spirometry measurements were compared with Wilcoxon’s test. Results: Sixty-six HIV-diagnosed patients, with a mean age of 31.5 years were included; 64 were males and two females. The prevalence of COPD was 7.6 %. The group with obstruction had a lower CD4 count (27.3 versus 225.9) and higher viral load (165,000 versus 57,722), in comparison with the group without obstruction. A positive correlation was observed between lower viral load and higher forced expiratory volume in 1 second/forced vital capacity ratio. Conclusion: HIV-positive patients with a lower CD4 count and a higher viral load show a decrease in spirometry values.


Resumen Introducción: La enfermedad pulmonar obstructiva crónica (EPOC) es el problema respiratorio de mayor prevalencia en el mundo. Los pacientes con infección por virus de la inmunodeficiencia humana (VIH) tienen mayor prevalencia de tabaquismo e infecciones pulmonares recurrentes y mayor riesgo de EPOC. Objetivo: Determinar la prevalencia de la EPOC en pacientes con diagnóstico de VIH referidos a un hospital de infectología. Método: Se incluyeron individuos con infección por VIH sin tratamiento antirretroviral previo o actual, con sintomatología respiratoria crónica, con o sin antecedentes de exposición para desarrollar EPOC. Se realizó espirometría pre y posbroncodilatación, tomografía computarizada de alta resolución, determinación de carga viral y conteo de CD4. Las mediciones espirométricas se compararon con prueba de Wilcoxon. Resultados: Se incluyeron 66 pacientes con diagnóstico de VIH, con edad de 31.5 años; 64 hombres y dos mujeres. La prevalencia de EPOC fue de 7.6 %. El grupo con obstrucción presentó menor conteo de CD4 (27.3 versus 225.9) y mayor carga viral (165 000 versus 57 722), en comparación con el grupo sin obstrucción. Se observó correlación positiva entre menor carga viral y mayor relación de volumen espiratorio forzado al primer segundo/capacidad vital forzada. Conclusión: Los pacientes VIH-positivos con menor conteo de CD4 y mayor carga viral presentan disminución de los valores espirométricos.

ABSTRACT

ABSTRACT Objective: To analyze symptoms at different times of day in patients with COPD. Methods: This was a multicenter, cross-sectional observational study conducted at eight centers in Brazil. We evaluated morning, daytime, and nighttime symptoms in patients with stable COPD. Results: We included 593 patients under regular treatment, of whom 309 (52.1%) were male and 92 (15.5%) were active smokers. The mean age was 67.7 years, and the mean FEV1 was 49.4% of the predicted value. In comparison with the patients who had mild or moderate symptoms, the 183 (30.8%) with severe symptoms were less physically active (p = 0.002), had greater airflow limitation (p < 0.001), had more outpatient exacerbations (p = 0.002) and more inpatient exacerbations (p = 0.043), as well as scoring worse on specific instruments. The most common morning and nighttime symptoms were dyspnea (in 45.2% and 33.1%, respectively), cough (in 37.5% and 33.3%, respectively), and wheezing (in 24.4% and 27.0%, respectively). The intensity of daytime symptoms correlated strongly with that of morning symptoms (r = 0.65, p < 0.001) and that of nighttime symptoms (r = 0.60, p < 0.001), as well as with the COPD Assessment Test score (r = 0.62; p < 0.001), although it showed only a weak correlation with FEV1 (r = −0.205; p < 0.001). Conclusions: Dyspnea was more common in the morning than at night. Having morning or nighttime symptoms was associated with greater daytime symptom severity. Symptom intensity was strongly associated with poor quality of life and with the frequency of exacerbations, although it was weakly associated with airflow limitation.


RESUMO Objetivo: Analisar os sintomas em diferentes momentos do dia em pacientes com DPOC. Métodos: Estudo observacional multicêntrico de corte transversal em oito centros brasileiros. Foram avaliados os sintomas matinais, diurnos e noturnos em pacientes com DPOC estável. Resultados: Foram incluídos 593 pacientes em tratamento regular, sendo 309 (52,1%) do sexo masculino e 92 (15,5%) fumantes ativos. A média de idade foi de 67,7 anos, e a média de VEF1 foi de 49,4% do valor previsto. Os pacientes com sintomas mais graves (n = 183; 30,8%), em comparação com aqueles com sintomas leves e moderados, apresentaram pior nível de atividade física (p = 0,002), maior limitação ao fluxo aéreo (p < 0,001), exacerbações ambulatoriais (p = 0,002) e hospitalares (p = 0,043) mais frequentemente e piores resultados em instrumentos específicos. Os sintomas matinais e noturnos mais frequentes foram dispneia (em 45,2% e 33,1%, respectivamente), tosse (em 37,5% e 33,3%, respectivamente) e chiado (em 24,4% e 27,0%, respectivamente). Houve forte correlação da intensidade dos sintomas diurnos com sintomas matinais (r = 0,65, p < 0,001), sintomas noturnos (r = 0,60, p < 0,001), bem como com o escore do COPD Assessment Test (r = 0,62; p < 0,001); porém, houve uma correlação fraca com VEF1 (r = −0,205; p < 0,001). Conclusões: A dispneia foi mais frequente no período matinal do que no período noturno. Ter sintomas matinais e/ou noturnos foi associado à pior gravidade dos sintomas diurnos. A intensidade dos sintomas foi fortemente associada a pior qualidade de vida e frequência de exacerbações, mas fracamente associada à limitação ao fluxo aéreo.

ABSTRACT

Introducción: La enfermedad pulmonar obstructiva crónica es el problema respiratorio de mayor prevalencia e impacto socioeconómico en el mundo a pesar de ser una enfermedad potencialmente prevenible. Objetivo: Comparar clínica y funcionalmente pacientes con diagnóstico de enfermedad pulmonar obstructiva crónica severa y muy severa. Métodos: Se realizó un estudio descriptivo en pacientes con diagnóstico clínico-espirométrico de enfermedad pulmonar obstructiva crónica severa o muy severa según sexo que acudieron al Hospital Neumológico Benéfico Jurídico en el periodo de septiembre de 2015 a marzo de 2017. Se empleó para las variables cuantitativas la media y la desviación estándar y el análisis de significación estadística mediante la prueba t de student. La muestra estuvo constituida por 50 pacientes, 25 hombres y 25 mujeres. Resultados: Las mujeres tuvieron menos exacerbaciones con una diferencia de las medias de 0,7 (IC 95 por ciento masculino 2.4-3.1; femenino 1,6-2.5; p=0,01). La sensación de disnea fue mayor en los hombres, con una diferencia de las medias de 0,6 (IC 95 por ciento masculino 2,4-3,1; femenino 1,8-2,5; p=0,00). En la capacidad al ejercicio según la PM6M las mujeres alcanzaron mejores porcentajes del predicho con una diferencia de las medias de 12,8 por ciento (IC 95 por ciento masculino 49,2-63,5; femenino 62,6-75,7; p=0.00). Conclusiones: Los hombres presentan más complicaciones que las mujeres con iguales características espirométricas(AU)


Introduction: Chronic obstructive pulmonary disease is a respiratory problem with the highest prevalence and socioeconomic impact in the world, despite being a potentially preventable disease. Objective: To compare clinically and functionally patients diagnosed with severe and very severe chronic obstructive pulmonary disease. Methods: A descriptive study was carried out in patients with a clinical-spirometric diagnosis of severe or very severe chronic obstructive pulmonary disease, according to sex. They were assisted at the Benéfico Jurídico Neurologic Hospital from September 2015 to March 2017. It was used for the quantitative variables the mean and standard deviation and the statistical significance analysis using the student's t test. Fifty patients formed the sample, 25 men and 25 women. Results: Women had fewer exacerbations with a means difference of 0.7 (95 percent CI male 2.4-3.1; female 1.6-2.5; p = 0.01). The dyspnea sensation was greater in men, with a means difference of 0.6 (95 percent CI male 2.4-3.1; female 1.8-2.5; p = 0.00). In the exercise capacity according to PM6M, women achieved better percentages than predicted with a means difference of 12.8 percent from (95 percent CI male 49.2-63.5; female 62.6-75.7; p = 0.00). Conclusions: Men present more complications than women with the same spirometrical characteristics(AU)

ABSTRACT

RESUMEN La enfermedad pulmonar obstructiva crónica se caracteriza por una limitación crónica al flujo aéreo poco reversible y asociada en particular al humo de tabaco. Se trata de una enfermedad infradiagnosticada y con una elevada morbimortalidad, lo que implica un problema de salud pública de gran magnitud. Constituye la cuarta causa de muerte en los países del Caribe y se prevé que su prevalencia siga en aumento, lo que representa un elevado costo sanitario. En Cuba la enfermedad pulmonar obstructiva crónica constituye la quinta causa de muerte con una tendencia ascendente en los próximos años, por lo que es un problema de salud, del que no se excluye la provincia de Matanzas, como causa de ingresos frecuentes en sus unidades de atención al grave, las cuales en ocasiones presentan una evolución desfavorable. Entre los factores de riesgo que incrementan esta entidad se encuentran el tabaquismo y la contaminación ambiental, que aumentan la morbilidad por esta entidad con complicaciones que prolongan la estadía hospitalaria y elevan la mortalidad (AU).


SUMMARY Chronic obstructive pulmonary disease is characterized by the chronic limitation of the airflow, almost irreversible and mainly associated to tobacco smoke. It is an underdiagnosed disease with a high morbimortality, meaning a health problem of high magnitude. It is the fourth cause of death in the Caribbean countries and it is expected its prevalence will still increase, representing a high sanitary cost. In Cuba, it is the fifth cause of death with an increasing tendency in the next years, being a health problem because it causes frequent admissions in the Seriously-ill Care Units, frequently having an unfavorable evolution. The province of Matanzas is not excluded from this. Smoking and environmental pollution are among the risk factors favoring this entity, increasing this entity morbidity with complications that make hospital staying longer and mortality higher (AU).

ABSTRACT

Abstract Introduction: Many publications on coronary surgery and carotid stenosis (CS) can be found, but we do not have enough information about the relationship between ischemic stroke, CS and non-coronary cardiac surgery. Objectives: To evaluate the incidence and risk factors associated with the stroke and CS ≥50% in patients undergoing non-coronary surgeries. Objectives: We assessed 241 patients, aged 40 years or older, between 2009 and 2016, operated in Santa Casa de Misericórdia de Ponta Grossa-PR, Brazil. We perform carotid Doppler in patients 40 years of age or older before any cardiac surgery as a routine. The incidence and possible risk factors for CS ≥50% and perioperative stroke were analyzed by univariate statistical analysis. Results: 11 patients (4.56%) presented perioperative stroke. The risk factor for stroke was CS ≥50%: OR=5.3750 (1.2909-22.3805), P=0.0208. Eighteen patients (7.46%) had CS ≥50% and their risk factors were extracardiac arteriopathy: OR=18.6607 (6.3644-54.7143), P<0.0001; COPD: OR=3.9040 (1.4491-10.5179), P=0.0071; diabetes mellitus: OR=2.9844 (1.0453-8.5204), P=0.0411; recent myocardial infarction: OR=13.8125 (1.8239-104.6052), P=0.0110; EuroSCORE II higher P=0.0056. Conclusion: The incidences of stroke and CS ≥50% were 4.56% and 7.46%, respectively. The risk factor for stroke was CS ≥50% and for CS ≥50% were extracardiac arteriopathy, COPD, diabetes mellitus, recent myocardial infarction and higher EuroSCORE II.

ABSTRACT

AIM: Chronic obstructive pulmonary disease (COPD) is a pro-inflammatory condition leading to wasting states such as sarcopenia. We aimed to describe the effect of COPD and sarcopenia on mortality in Costa Rican older adults in the Costa Rican Longevity and Healthy Aging Study (CRELES). METHOD: This is a secondary analysis of the CRELES, a cohort study consisting of three waves of interviews. For the current study, data from the first and third waves were used. The dependent variable was survival status. COPD and sarcopenia were independent variables. Bivariate analyses were used to compare mortality curves for each group. Association with 3-year mortality was tested with Cox regression models, and hazard ratios (HR) with 95% confidence intervals (CI) were estimated as a measure of the strength of association. RESULTS: Of a total of 2704 participants, 54.29% (n = 1468) were women. Overall mortality was 9.05%. Sarcopenic older adults had the strongest association with mortality (HR = 2.65; 95%CI, 1.81­3.90; p < 0.001), followed by those with both COPD and sarcopenia (HR = 2.59; 95%CI, 1.37­4.92; p = 0.003). The weakest association with mortality was found in patients with neither COPD nor sarcopenia. CONCLUSIONS: The synergistic effect of sarcopenia and COPD has been shown to independently increase mortality in older patients. Our results may be applicable to both Latin American residents and subjects of Hispanic descent living in developed countries. Sarcopenia should be assessed in all patients with COPD since the latter is not a disease limited to the lungs, but rather a systemic disease.


OBJETIVO: A doença pulmonar obstrutiva crônica (DPOC) é uma condição pró-inflamatória que conduz a estados de perda como a sarcopenia. Nosso objetivo foi descrever o efeito da DPOC e da sarcopenia sobre a mortalidade em idosos costa-riquenhos do estudo Costa Rican Longevity and Healthy Aging Study (CRELES). MÉTODO: Esta é uma análise secundária do CRELES, um estudo de coorte composto por três ondas de entrevistas. Para o presente estudo, foram utilizados dados da primeira e terceira ondas. A variável dependente foi o status de sobrevida. DPOC e sarcopenia foram variáveis independentes. Foram realizadas análises bivariadas para comparar as curvas de mortalidade para cada grupo. Testou-se a associação à mortalidade em 3 anos com modelos de regressão de Cox, e razões de risco (HR) com intervalos de confiança (IC) de 95% foram estimadas como medida da força da associação. RESULTADOS: De um total de 2704 participantes, 54,29% (n = 1468) eram mulheres. A mortalidade geral foi 9,05%. Idosos sarcopênicos apresentaram a associação mais forte à mortalidade (HR = 2,65; IC95%, 1,81­3,90; p < 0,001), seguidos por aqueles com DPOC e sarcopenia (HR = 2,59; IC95%, 1,37­4,92; p = 0,003). A associação mais fraca à mortalidade foi encontrada em pacientes sem DPOC e sarcopenia. CONCLUSÕES: Demonstrou-se que o efeito sinérgico da sarcopenia e da DPOC aumenta de forma independente a mortalidade em pacientes idosos. Nossos resultados podem ser aplicáveis a residentes latino-americanos e a descendentes de hispânicos que vivem em países desenvolvidos. A sarcopenia deve ser avaliada em todos os pacientes com DPOC, visto que esta não é uma doença limitada aos pulmões, mas sim uma doença sistêmica.

ABSTRACT

RESUMEN Introducción: La presencia de aire dentro de la cavidad pleural es definida como neumotórax. El tratamiento quirúrgico inicial es la pleurostomía, que puede acarrear complicaciones, relacionadas con varios factores, entre los cuales se encuentra el diámetro de la sonda intratorácica utilizada. Objetivo: Evaluar los resultados del tratamiento con pleurostomía en pacientes con neumotórax espontáneo en el Hospital Universitario Manuel Ascunce Domenech. Método: Se realizó un estudio descriptivo longitudinal retrospectivo desde septiembre de 2012 hasta septiembre de 2017. Se estudiaron 63 pacientes afectos de neumotórax espontáneos que recibieron pleurostomía como tratamiento inicial. Resultados: Los neumotórax espontáneos primarios representaron 56 por ciento de los casos. Del total de pacientes, 82 por ciento eran fumadores. En todos los pacientes el síntoma predominante fue el dolor. Las complicaciones fueron más frecuentes con el uso de sondas pleurales de menor diámetro (86 por ciento). Conclusiones: El neumotórax espontáneo primario fue el de mayor frecuencia. Las causas predominantes en el neumotórax secundario fueron las bulas de enfisema y la enfermedad pulmonar obstructiva crónica. En la totalidad de los casos, estuvo presente algunos de los síntomas del síndrome pleural con predominancia absoluta del dolor. El mayor número de complicaciones se presentó en pacientes fumadores(AU)


ABSTRACT Introduction: The presence of air within the pleural cavity is defined as pneumothorax. The initial surgical treatment is pleurostomy, which can lead to complications associated with several factors, among which is the diameter of the intrathoracic probe that is used. Objective: To evaluate the outcomes of the treatment with pleurostomy in patients with spontaneous pneumothorax at Manuel Ascunce Domenech University Hospital. Method: A retrospective, longitudinal, descriptive study was conducted from September 2012 to September 2017. We studied 63 patients affected by spontaneous pneumothorax who received pleurostomy as initial treatment. Results: Primary spontaneous pneumothorax accounted for 56 percent of the cases. From the total amount of patients, 82 percent were smokers. In all patients, the predominant symptom was pain. Complications were more frequent with the use of pleural probes of smaller diameter (86 percent). The primary spontaneous pneumothorax was the most frequent. The predominant causes of secondary pneumothorax were bullous emphysema and chronic obstructive pulmonary disease. In all the cases, some of the symptoms of pleural syndrome with absolute predominance of pain were present. The greatest number of complications occurred in smoking patients. Conclusions: Pleurostomy, with the use of the drainage catheter, is the initial treatment for all patients with spontaneous pneumothorax in our hospital, regardless of the diameter of the probe to be used according to the type of pneumothorax (primary or secondary)(AU)

ABSTRACT

ABSTRACT Objective: To evaluate the anthropometric data obtained for residents of the city of São Paulo, Brazil, in a study of Latin America conducted in two phases (baseline, in 2003, and follow-up, in 2012). Methods: This was an analysis of data obtained for São Paulo residents in a two-phase population-based study evaluating the prevalence of COPD and its relationship with certain risk factors among individuals ≥ 40 years of age. The anthropometric data included values for weight, height, body mass index (BMI), and waist circumference. In the follow-up phase of that study, the same variables were evaluated in the same population sample as that of the baseline phase. Results: Of the 1,000 São Paulo residents enrolled in the baseline phase of that study, 587 participated in the follow-up phase, and 80 (13.6%) of those 587 subjects had COPD. Comparing the baseline and follow-up phases, we found increases in all anthropometric measures in both groups (COPD and non-COPD), although the differences were significant only in the non-COPD group. The subjects with mild COPD showed increases in weight and BMI (Δweight = 1.6 ± 5.7 and ΔBMI = 0.7 ± 2.2), whereas those with moderate or severe COPD showed reductions (Δweight = −1.7 ± 8.1 and ΔBMI = −0.4 ± 3.0), as did those with severe or very severe COPD (Δweight = −0.5 ± 5.4 and ΔBMI = −0.8 ± 3.3). Conclusions: Between the two phases of the study, the subjects with mild COPD showed increases in weight and BMI, whereas those with a more severe form of the disease showed reductions.


RESUMO Objetivo: Avaliar a evolução dos dados antropométricos obtidos em uma pesquisa latino-americana realizada em duas fases (basal, em 2003, e seguimento, em 2012) na cidade de São Paulo. Métodos: Estudo de base populacional que avaliou indivíduos com idade ≥ 40 anos com o objetivo de definir a prevalência da DPOC e sua relação com alguns fatores de risco. A avaliação antropométrica incluiu medições de peso, altura, índice de massa corpórea (IMC) e circunferência abdominal. Foram avaliadas as mesmas variáveis na mesma população na fase de seguimento. Resultados: Dos 1.000 indivíduos incluídos inicialmente, 587 participaram da fase de seguimento; desses, 80 (13,6%) tinham DPOC. Entre a avaliação inicial e a de seguimento ambos os grupos (DPOC e não DPOC) apresentaram aumentos nas medidas antropométricas, mas esses somente foram significativos no grupo não DPOC. Os indivíduos com DPOC leve tiveram aumentos de peso e IMC (Δpeso = 1,6 ± 5,7 kg e ΔIMC = 0,7 ± 2,2 kg/m2) enquanto aqueles com doença moderada ou grave tiveram reduções dessas medidas (DPOC moderada: Δpeso = −1,7 ± 8,1 kg e ΔIMC = −0,4 ± 3,0 kg/m2; e DPOC grave ou muito grave (Δpeso = −0,5 ± 5,4 kg e ΔIMC = −0,8 ± 3,3 kg/m2). Conclusões: Entre as duas fases da pesquisa, os pacientes com DPOC leve tiveram aumento de peso e IMC, enquanto aqueles com doença mais grave apresentaram perda ponderal e redução do IMC.

ABSTRACT

INTRODUCCIÓN: La Enfermedad Pulmonar Obstructiva Crónica afecta a 260 millones de personas a nivel mundial y representará la tercera causa de muerte para el año 2020. MATERIALES Y MÉTODOS: Se realizó un estudio observacional descriptivo transversal con la finalidad de comparar la estadificación de un grupo de pacientes venezolanos con EPOC según la Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2007, 2011 y 2019. RESULTADOS: La muestra estuvo constituida por ochenta y nueve (89) pacientes con una edad promedio de 66,7 ± 0,9 años, siendo el 60,7% de los pacientes del sexo masculino y 82% fumadores. El 14,6% de los pacientes presentaban EPOC leve, 36% EPOC moderado, 41,6% EPOC severo y 7,9% EPOC muy severo. El valor del test Kappa de Cohen entre las escalas mMRC y CAT (COPD Assessment Test) fue de 0,529 (GOLD 2011) y 0,555 (GOLD 2019). CONCLUSIONES: 1) la poca concordancia entre el VEF1, grado de disnea e historial de exacerbaciones impacta la clasificación de la severidad de la EPOC al utilizar GOLD 2011; 2) la concordancia moderada entre las escalas mMRC y CAT sugiere que el tipo de cuestionario utilizado afecta la categorización de la severidad de la enfermedad; 3) los pacientes del grupo B mostraron una importante afectación en el intercambio gaseoso dado por valores más bajos de DLCO y oximetría arterial y 4) una proporción significativa de pacientes fueron clasificados en los grupos de alto riesgo (B y D) en GOLD 2011 y 2019.


INTRODUCTION: Chronic Obstructive Pulmonary Disease (COPD) affects 260 million people worldwide and it is thought to become the third leading cause of mortality by the year 2020. MATERIAL AND METHODS: A transversal descriptive observational study was conducted to compare the categorization of a group of Venezuelan COPD patients according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2007, 2011 and 2019. RESULTS: Eighty-nine (89) patients with a mean age of 66.7 ± 0.9 years were included, 60.7% were male and 82% smokers. 14.6% of the patients had mild COPD, 36% moderate COPD, 41.6% severe COPD and 7.9% very severe COPD. Cohen's Kappa coefficient value between mMRC and COPD Assessment test (CAT) was 0,529 (GOLD 2011) and 0,555 (GOLD 2019). CONCLUSIONS: 1) the lack of concordance between FEV1 values, degree of dyspnea and history of exacerbations impacts COPD severity classification when using GOLD 2011; 2) moderate agreement between mMRC and CAT scales suggests that the type of questionnaire used to evaluate perception of dyspnea can affect disease severity categorization; 3) group B patients showed a significant gas exchange impairment due to lower values of DLCO and arterial oxymetry and 4) a significant proportion of patients were categorized in the high-risk groups (B and D) both in GOLD 2011 and 2019. Optimization of the evaluation of COPD severity is important to allow a better standardization of care and pharmacological management of patients with this disease.

ABSTRACT

INTRODUCCIÓN La presencia de anemia en la enfermedad pulmonar obstructiva crónica es un hecho frecuente. Las exacerbaciones de esta enfermedad se han asociado a un incremento de la mortalidad en estos pacientes. No es claro si la presencia de anemia se vincula al riesgo de exacerbaciones. OBJETIVO Establecer la asociación entre anemia e incidencia de desenlaces relacionados con las exacerbaciones de la enfermedad pulmonar obstructiva crónica. MÉTODOS Estudio analítico de una cohorte dinámica o abierta, prospectiva y concurrente de pacientes con diagnóstico de enfermedad pulmonar obstructiva crónica de dos instituciones de atención en salud de Cartagena, Colombia, entre julio de 2010 y julio de 2011. RESULTADOS De los casos revisados, 43,9% presentó anemia al inicio del seguimiento. La incidencia acumulada de exacerbaciones fue de 63% en el grupo de pacientes anémicos versus 55,5% en el grupo de no anémicos. La incidencia acumulada de recurrencia de exacerbaciones fue de 30,4% en el grupo de anémicos versus 38,8% en el grupo de no anémicos. La tasa de hospitalizaciones por exacerbaciones fue de 30,4% en el grupo de anémicos versus 33,3% en el grupo de no anémicos. CONCLUSIONES No se estableció asociación significativa entre la anemia y la incidencia de exacerbaciones de enfermedad pulmonar obstructiva crónica, la incidencia de recurrencia de la primera exacerbación, la tasa de hospitalizaciones por exacerbaciones de enfermedad pulmonar obstructiva crónica y el tiempo hasta la recurrencia de la primera exacerbación de enfermedad pulmonar obstructiva crónica.


BACKGROUND The presence of anemia in chronic obstructive pulmonary disease is not an infrequent event. Exacerbations of this disease have been associated with an increase in mortality in these patients. It is not clear if the presence of anemia is associated with the risk of exacerbations. OBJECTIVE To establish the association between anemia and the incidence of outcomes related to exacerbations of chronic obstructive pulmonary disease. METHODS Analytical study of a dynamic or open concurrent prospective cohort of patients diagnosed with chronic obstructive pulmonary disease at two health care institutions in Cartagena, Colombia, between July 2010 and July 2011. RESULTS 43.9% had anemia at the start of follow-up. The cumulative incidence of exacerbations was 63% in the anemic vs. 55.5% in the non-anemic group. The cumulative incidence of recurrence of exacerbations was 30.4% in the anemic vs. 38.8% in the non-anemic group. The rate of hospitalizations for exacerbations was 30.4% in the anemic vs. 33.3% in the non-anemic group. CONCLUSIONS No significant association was established between anemia and the incidence of exacerbations of chronic obstructive pulmonary disease, the incidence of recurrence of first exacerbation, the rate of hospitalizations for chronic obstructive pulmonary disease exacerbations and the recurrence time of the first exacerbation of chronic obstructive pulmonary disease.
