ABSTRACT

El neumonólogo de adultos acostumbra a prescribir vacunas. Este documento hecho por expertos en aspectos de la especialidad que involucran vacunar a pacientes con enfermedades respiratorias, perteneciente a la Asociación Argentina de Medicina Respiratoria, resumió la información disponible proponiendo una participación activa en la vacunación contra influenza (VAG), neumococo (VAN), pertusis y zoster. El Ministerio de Salud (MSAL) en Argentina, como el CDC y su comité de consulta sobre inmunización (ACIP) en Estados Unidos, elaboran calendarios y recomendaciones para vacunación. La ACIP recomienda la VAG a mayores de 6 meses sin contraindicaciones; el MSAL a mayores de 65 años y a quienes tengan comorbilidades (incluye enfermedades respiratorias y tabaquismo) o contacto con personas vulnerables. La clásica VAN polisacárida de 23 serotipos es recomendada para adultos con riesgo de enfermedad invasiva, incluyendo a mayores de 65 años, revacunando a los inmunosuprimidos y una única vez a los mayores de 65 que hubieran sido vacunados 5 años antes o más; la ACIP recomienda dar la VAN conjugada de 13 serotipos, más inmunogénica, secuencialmente con la polisacárida de 23, en adultos con factores de riesgo y en mayores de 65 años. Sugerimos usarla en menores de 65 con comorbilidad respiratoria. El neumonólogo debe recordar al menos 2 vacunas más: dar el refuerzo decenal contra difteria y tétanos (DT) en mayores de 18, una vez con vacuna triple acelular (difteria, pertusis y tétanos) protegiendo contra pertusis y reduciendo su transmisión. El herpes zoster produce un rash cutáneo vesicular doloroso. Uno cada 2 mayores de 85 sufrirán al menos un ataque de herpes zoster. La vacuna reduce más del 50% la incidencia y más del 60% la neuralgia post herpética; el ACIP la recomienda en mayores de 60 años. Un gran número de los pacientes con afecciones pulmonares crónicas tienen esa edad.


The pulmonologist uses to prescribe vaccines to adult patients. Experts of the Argentina Association of Respiratory Medicine who are specialists in areas involving vaccination of patients with respiratory diseases prepared this document which summarizes the available information and proposes an active prescription of the infuenza, pneumococcus, pertussis and herpes zoster vaccinations. The Ministry of Health in Argentina as the CDC and its Advisory Committee on Immunization Practices (ACIP) in the USA, made recommendations on vaccination indications and schedules. The ACIP recommends influenza vaccination to persons older than 6 months of age without any contraindication. The Ministry of Health recommends this vaccination to persons over 65 years of age, to those with morbidities (including respiratory diseases and smoking habit) and to persons in contact with high risk people. The classic 23-valent polysaccharide pneumococcal vaccine is recommended for adults at risk of invasive disease, including persons over 65 years of age. Revaccination is recommended to immunosuppressed patients and persons over 65 years of age at 5-year intervals. The ACIP recommends vaccination with the 13-valent serotypes polysaccharide pneumococcal vaccine, which is more immunogenic, sequentially with the 23-valent vaccine in adults with risk factors and over 65 years of age. We suggest this practice in patients under 65 years of age with respiratory morbidities. The pulmonologist must remember at least two other vaccines: a booster vaccination every 10 years of diphtheria and tetanus vaccine to persons over 18 years of age, and once the triple acellular vaccine (diphtheria, pertussis and tetanus) to protect against pertussis and reduce transmission. Herpes zoster (shingles) causes a painful vesicular rash; 50% of persons over 85 years suffer at least one bout of herpes zoster. The vaccine reduces more than 50% incidence and more than 60% postherpetic neuralgia. This vaccine is recommended by ACIP for persons over 60 years. In this age group there are many patients with chronic lung conditions.

ABSTRACT

La participación en un Programa de Rehabilitación Respiratoria (PRR) mejora la disnea, la capacidad funcional y la calidad de vida en pacientes con enfermedad respiratoria crónica. Sin embargo, la adherencia a PRR suele ser baja. Se realizó un estudio retrospectivo con el objetivo de identificar variables relacionadas con la adherencia a un PRR ambulatorio en un centro de la Argentina y secundariamente evaluar los resultados en quienes adhirieron. El PRR incluyó una etapa de "adquisición" que consistió en 16 semanas de entrenamiento físico supervisado, dos veces por semana, y clases sobre los beneficios del tratamiento, el uso de los dispositivos de inhalación, cesación tabáquica, reconocimiento de síntomas y manejo de las exacerbaciones, entre otros. Al finalizar el entrenamiento los pacientes fueron re-evaluados. Se consideró "adherencia al PRR" cuando el paciente completó la etapa de adquisición. De 388 pacientes que iniciaron la primera evaluación, 102 (26.3%) adhirieron al PRR. Se utilizó regresión logística múltiple (Forward Stepwise con ingreso de variables con p < 0.10) para identificar factores relacionados con "adherencia al programa". El modelo final fue el siguiente: poseer obra social (OR = 3.99; IC90% = 2.24-7.12), tiempo de viaje al hospital menor de 60 minutos (OR = 2.07; IC90% = 1.37-3.11) e ingreso económico disponible (OR = 2.11; IC90% = 1.03-4.31). Los pacientes que adhirieron al PRR presentaron mejoría significativa en la prueba de marcha de 6 minutos y en la calidad de vida. Los resultados alertan sobre la baja adherencia y su relación con las variables socioeconómicas.


Participation in a Pulmonary Rehabilitation Program (PRP) improves dyspnea, functional capacity and quality of life in patients with chronic respiratory disease. A retrospective study was carried out to identify variables related to compliance in an out patient PRP at an Argentine center and to evaluate the results in compliant patients. The PRP included an "acquisition" stage consisting of 16 weeks of supervised training twice weekly and lectures on treatment benefits, inhalation devices used, smoking cessation, symptoms recognition and flair up management, among others. Patients were reassessed after this stage. Patients completing the acquisition stage were considered PRP compliant. Of 388 patients evaluated for admission 102 (26.3%) complied with PRP. Multiple logistic regression analysis (Forward Stepwise; p < 0.10 to be eligible for entry into the model) was used to identify factors related to "program compliance". The final model was as follows: having health insurance coverage (OR = 3.99; CI90% = 2.24-7.12), commute time under 60minutes (OR = 2.07; CI90% = 1.37-3.11) and financial capacity (OR = 2.11; CI90% = 1.03-4.31). All patients complied with the PRP showed significant improvement in the six-minute walking test and quality of life. The results warn about low compliance and their relationship with socioeconomic variables.

ABSTRACT

The Argentine Society for Infectious Diseases and other national societies issued updated practical guidelines for the management of acute bronchitis (AB) and reactivations of chronic obstructive pulmonary disease (COPD) with the aim of promoting rational use of diagnostic and therapeutic resources. AB is a condition characterized by inflammation of the bronchial airways which affects adults and children without underlying pulmonary disease. It is usually caused by a virus. The diagnosis is based on clinical findings after community acquired pneumonia has been ruled out. Treatment of AB is mainly symptomatic. Antibiotics should be used in immune-compromised hosts, patients with chronic respiratory or cardiac diseases and in the elderly with co-morbidities. Reactivation of COPD is defined as an acute change in the patient’s baseline clinical situation beyond normal day to day variations, with an increase in dyspnea, sputum production and/or sputum purulence, warranting a change in medication. An increase in one symptom is considered a mild exacerbation, two as moderate, and the presence of three symptoms is considered a severe exacerbation. An infectious agent can be isolated in sputum in 50 to 75


of COPD reactivations. Moderate and severe episodes must be treated with antibiotics, amoxicillin/ beta-lactamase inhibitor, macrolides and fluoroquinolones are first choice drugs.

ABSTRACT

Introducción: Los pacientes con enfermedad pulmonar difusa (EPD) a menudo presentan fragmentación del sueño con microdespertares frecuentes. En este grupo de pacientes, la desaturación nocturna de oxígeno es frecuente con una prevalencia de 50- 80%. Se agrava en el sueño REM y se asocia con una menor calidad de vida, pudiendo contribuir al daño vascular a largo plazo. La presencia de apneas obstructivas del sueño (AOS) se presenta en el 20% de la población adulta general. Objetivos: Describir las características de los parámetros respiratorios clínicos y fisiológicos y la frecuencia de los trastornos respiratorios del sueño (TRS), especialmente de AOS, en pacientes con EPD. Materiales y métodos: Se incluyeron prospectivamente pacientes con diagnóstico establecido de EPD que consultaron en un hospital especializado en enfermedades respiratorias entre julio de 2010 y enero de 2012. Se les realizó polisomnografía (PSG) y estudio de función pulmonar (CVF y DLCO). Resultados: Se estudiaron 41 pacientes con edad promedio de 61.5 ± 12.6 años. El 54% eran hombres (n = 22). Los diagnósticos de EPD fueron neumonía intersticial usual (NIU) en el 70.7%, neumonía intersticial no específica (NINE) en el 14.6%, neumonitis por hipersensibilidad (NHS) en el 9.8% y proteinosis alveolar pulmonar (PAP) en el 4.8%. El índice de masa corporal (IMC) medio fue 29.4 ± 4.4 kg/m². En el 80% fue = 25 y en el 41% = 30. La CVF media fue de 2.18 ± 0.7 l y 64.8 ± 16.8 del porcentaje del predictivo. La DLCO ajustada a la Hb media fue de 10.3±3.6 ml/mmHg/min y 46.9 ± 14 del porcentaje del valor predictivo. Con respecto a la PSG, la SpO2 basal media fue de 93.9 ±3.4%, la saturación media durante el sueño fue 89.8 ±7% y en el 39% de los casos la SpO2 media era < 90%. En el 90% de los casos la SpO>2 mínima durante el sueño fue menor de 90%. El 34% de los casos presentaba CT 90 (tiempo con SpO2 < 90%) > 50%. De los 13 pacientes con SpO2 basal despierto > 95%, 3 presentaron un CT90 = 20% yv de los 27 pacientes con SpO2 basal > 92%, 10 cursaban con un CT90 = 20%.v Del total de los pacientes, el 48.8% presentaba AOS. El índice de apneas-hipoapneasv (IAH) medio fue 11.4 y el 20% de los pacientes presentó IAH = 15. Con respecto a la escala de somnolencia de Epworth (ESE), el 45% de los pacientes conv AOS presentaba una ESE = 10, que resultó significativamente mayor en comparación conv el grupo sin AOS. Del grupo de pacientes con IAH = 15, el 62.5% presentaban ESE < 10. Conclusiones: Un número importante de pacientes sin hipoxemia en reposo presentan desaturación durante el sueño. En este estudio, la frecuencia de AOS fue del 48.8%. Además, el grupo de pacientes con EPD con AOS presentó mayor compromiso oximétrico medido a través de CT90. Globalmente, el grupo de pacientes con AOS presentaba mayores valores de FVC (71.25% vs 58.67 p = 0.019).


Background: Patients with interstitial lung disease (ILD) often have sleep fragmentation with frequent arousals. In this group of patients, nocturnal oxygen desaturation is common, with a prevalence of 50-80%. It is worse in Rapid Eye Movement (REM) sleep, is associated with reduced quality of life and can contribute to long-term vascular damage. The presence of obstructive sleep apnea (OSA) occurs in 20% of the general adult population. Aims: To describe the characteristics of clinical and physiological respiratory parameters and frequency of respiratory sleep disorders (RSD), especially OSA, in patients with ILD. Materials and Methods: We prospectively included ILD patients who attended a specialized hospital between July 2010 and January 2012. Polysomnography (PSG) and study of pulmonary function: Forced Vital Capacity (FVC) and Diffusing Lung Capacity for Carbon Monoxide (DLCO) were performed. Results: We studied 41 patients with a mean age of 61.5 ± 12.6 years. 54% were male (n = 22). ILD diagnoses were usual interstitial pneumonia (UIP) in 70.7%, nonspecific interstitial pneumonia (NSIP) in 14.6%, hypersensitivity pneumonitis (HP) in 9.8% and pulmonary alveolar proteinosis (PAP) in 4.8%. The body mass index (BMI) was 29.4 ± 4.4 kg/m²; it was = 25 in 80% of patients and = 30 in 41%. The mean FVC was 2.18 ± 0.7 l and 64.8 ± 16.8 in the percentage of predictive value. The DLCO adjusted to Hb mean was 10.3 ± 3.6 ml/mmHg/min and 46.9 ± 14 in the percentage of predictive value. Regarding the PSG, the mean baseline SpO2 was 93.9 ± 3.4%, the mean saturation during sleep was 89.8 ± 7%, and the mean SpO2 was < 90% in 39% of cases. In 90% of cases the minimum SpO2 during sleep was less than 90%; 34% of patients had CT 90 (time with SpO2 < 90%) > 50%. In 13 patients with baseline SpO2 > 95%, 3 had CT90 = 20% and 10 of the 27 patients with basal SpO2 > 92%, had CT90 = 20%. Of all patients, 48.8% had OSA. The mean apnea-hypopnea index ...

ABSTRACT

La hemosiderosis pulmonar idiopática (HPI) es una enfermedad rara de etiología desconocida, caracterizada por episodios recurrentes de hemorragia alveolar difusa (HAD). Existen múltiples condiciones asociadas con HAD, la mayoría de los casos ocurren en asociación con enfermedades sistémicas autoinmunes. La HPI es un diagnóstico de exclusión que se utiliza para describir los casos de HAD en los que no se encuentra una condición asociada. El objetivo del siguiente trabajo es la presentación de tres casos de HPI en mujeres adultas, revisión de la bibliografía disponible y por ultimo, remarcar la importancia de la biopsia pulmonar en el diagnostico definitivo de la HAD.


Idiopathic pulmonary hemosiderosis (IPH) is a rare lung disease of unknown etiology, characterized by recurrent episodes of diffuse alveolar hemorrhage (DAH). There are several conditions associated with DAH and most of them occur in association with systemic autoimmune diseases. IPH is diagnosed after other identifiable causes of alveolar bleeding have been excluded. The objectives of this paper is to present three cases of IPH in adult women, to review the literature and to underline the importance of lung biopsy in the definitive diagnosis of the DAH.

ABSTRACT

Las fluoroquinolonas de cuarta generación disponibles son levofloxacina y moxifloxacina.Tienen buena penetración en el interior de las bacterias y alta biodisponibilidad que permite el tratamiento por vía oral y el rápido pasaje de la vía parenteral a oral. Streptococcus pneumoniae es el patógeno más frecuente y que produce mayor número de muertes enneumonía adquirida en la comunidad (NAC), los llamados ®atípicos¼, Mycoplasma pneumoniae, Chlamydophyla pneumoniae y Legionella pneumophila son agentes comunes.Estos antibióticos tiene actividad frente a los gérmenes mencionados y a otros como H. influenzae, Staphylococcus aureus meticilino sensible, otros gram-positivos y gram-negativos, incluyendo Pseudomonas aeruginosa, y enterobacterias y anaerobios. La resistencia del neumococo a penicilina ocurre en todo el mundo, pero está creciendo también para otros antibióticos, en macrólidos puede llegar al 35%. Según la guía Infectious Diseases Society of America/American Thoracic Society la monoterapia con fluoroquinolonas es de primera línea en pacientes con riesgo de neumococo resistente, ambulatorios mayores ocon comorbilidades y hospitalizados en sala general, en un mismo plano a la combinación beta lactámico/macrólido. Si bien como monoterapia no parecen inferiores, se recomiendan en combinación con otros antibióticos en la neumonía grave en terapia intensiva.


Levofloxacin and moxifloxacin are the available fourth generation fluroquinolones. Their penetration into the pathogens and high bioavailability favor their use by the oral route andtheir rapid switch from the parenteral route. Streptococcus pneumoniae, the most frequently involved microorganism also has the higher fatality rate in community acquired pneumonia(CAP); the so called atypical Mycoplasma pneumoniae, Chlamydophyla pneumoniae andLegionella pneumophila are very common. These antimicrobials are active against the mentioned microorganisms and other pathogens as H. influenzae, methicillin susceptible Staphylococcus aureus, and other gram-positive and gram-negative organisms, includingPseudomonas aeruginosa, enteric bacteria and anaerobes. Penicillin resistance happens all over the world, also resistance to other antimicrobials is growing, for macrolides it is ashigh as 35%. According with the Infectious Diseases Society of America/American Thoracic Society guideline, fluoroquinolone monotherapy is in the first line in patients at risk forresistant pneumococcus, elderly or with comorbid illnesses outpatients and in those hospitalized not in the ICU, in the same level as the beta-actam/macrolide combination. Two different studies demonstrated that in patients with severe CAP admitted to the ICUfluoroquinolone monotherapy was not inferior to combination therapy; however the guideline recommends its use in combination with other antimicrobial.

ABSTRACT

Se realizó un estudio prospectivo sobre la utilización de la ventilación mecánica no invasiva (VNI) en pacientes internados en Clínica Médica Neumonológica por exacerbación de la enfermedad pulmonar obstructiva crónica (EPOC), con el objetivo de evaluar la evolución, los cambios gasométricos, las comorbilidades y la mortalidad de los pacientes internados. Desde enero 2000 a enero 2003 ingresaron al estudio 39 pacientes, evaluados según normas internacionales en 54 internaciones, siendo clasificados como de grado grave y muy grave, dado que la medición del volumen espiratorio forzado en un segundo (VEF1) era del 26%. Veintinueve pacientes (74.4%) presentaron alguna comorbilidad. Como consecuencia de la aplicación de la VNI, el pH se incrementó entre la primera y tercera medición. El pH promedio inicial fue de 7.25 llegando a 7.33 a las 2 horas y a 7.39 al alta, en tanto que la pCO2 con promedio inicial de 83.8 mm Hg llegó a 67.8 mm Hg y 54.2 mm Hg en el mismo período. Treinta y cinco de los 39 pacientes fueron dados de alta con un período de internación promedio de 13.6 días. Cuatro pacientes (10.3%) fallecieron. Se concluye que con la aplicación de la VNI en pacientes con exacerbación de EPOC, el pH y la PaCO2 cambian significativamente en las muestras sucesivas, y que la adecuada capacitación del equipo de salud puede permitir el tratamiento de estos pacientes en áreas de menor complejidad. Deben ser tenidas en cuenta las posibles complicaciones que pueden sufrir los pacientes durante la internación, que pueden requerir la aplicación de ventilación invasiva.


This is a prospective study on the implementation of the non-invasive positive pressure ventilation (NPPV) to treat respiratory failure resulting from exacerbation of chronic obstructive pulmonary disease (COPD) in patients hospitalized in a Pneumological Unit. From January 2000 to January 2003, 39 patients were included during 54 different exacerbation events after being evaluated under international standards. They were classified as severe and very severe patients on the basis of their FEV1 values of 26%. Twenty nine patients presented co-morbidities. As a consequence of the NPPV treatment, the pH values increased between the first and last register as well as the pCO2 dropped in the same period. The initial mean pH values were 7.25 reaching mean values of 7.33 at 2 hours and 7.39 at the discharge; the corresponding pCO2 mean values were 83.8 mmHg, 67.8 mmHg and 54.2 mmHg. Thirty five patients out of 39 were discharged after a mean hospitalization length of 13.6 days. Four patients died. Apropriate training of health care staff in general facilities could allow the implementation of NPPV in addition to usual medical care to treat exacerbation of COPD. High morbidity situations could arise during hospitalization, so invasive ventilation must be necessary.

ABSTRACT

Patients hospitalized with community acquired pneumonia were studied prospectively in two hospitals located in the surroundings of Buenos Aires city. Fifty two patients from General Hospital Manuel Belgrano (HMB) were included from March 1998 to February 1999 and 23 patients from Hospital Dr A. Cetrangolo (HCET) for respiratory disease, were included from June 2000 to May 2001. Patients with lung tuberculosis, lung neoplasia and HIV infection were excluded. Clinical background, signs and symptoms were recorded. Microbiological examinations performed included bacteria, respiratory viruses and mycobacteria. Studies for "atypical" bacteria (Chlamydia spp., Coxiella burnetii, Mycoplasma pneumoniae and Legionella spp.) were carried out by serological methods. No differences in age and gender were observed between both groups. Most frequently observed comorbidities in the HMB group included COPD, diabetes and cardiac failure while in the HCET group these were COPD, asthma and lung fibrosis. Etiology was established in 48% and 65.2% of the patients in the first and second group, respectively. Most frequent agents were Mycoplasma pneumoniae, Streptococcus pneumoniae, influenza A and Legionella spp.; the last one was detected in 12% of the patients. Most of these patients were from HMB and presented a good outcome. Mortality was similar in both groups (13.3%). In the HBM group it was related to the presence of comorbidities in 7 out of 8 cases, and in the HCET group it was a consequence of the worsening of their chronic respiratory failure
