Uso de lisados bacterianos en la prevención de la infección respiratoria recurrente en pediatría. Revisión sistemática de la literatura

Las infecciones respiratorias altas y bajas son una causa común de morbimortalidad infantil. Se ha propuesto el uso de los lisados bacterianos para prevenir las infecciones recurrentes sin embargo su uso aún se considera controversial. Metodología: Se realizó una revisión sistemática de la literatura. La búsqueda se realizó a través de las bases de datos PUBMED, Embase, Ovid, LiLaCS y Cochrane library plus. Se incluyeron metanálisis publicados en idiomas inglés y español, entre los años 1998 y 2012. Se realizó una evaluación de calidad siguiendo la estrategia Quorum y un análisis cualitativo y cuantitativo de los resultados. Resultados: Se incluyeron 4 revisiones sistemáticas de la literatura con metanálisis. Fue apreciable la disminución de las recurrencias de las infecciones respiratorias relacionadas con el uso de los lisados bacterianos. Los lisados bacterianos disminuyen la necesidad de uso de antibióticos. No se encontró evidencia sobre el uso de los lisados sobre desenlaces como la necesidad de intervenciones adicionales, tiempo de hospitalización, costo relacionado con la atención en salud. No se reportaron eventos adversos de importancia. Conclusión: Los lisados bacterianos son eficaces en disminuir la recurrencia de las infecciones respiratorias en pacientes en edad pediátrica.

Diferencias microbiológicas en pacientes con exacerbación severa de EPOC con o sin consolidación neumónica

La EPOC es una causa importante de morbilidad y mortalidad en el mundo y su prevalencia en Bogotá alcanza hasta 8,5%. Las exacerbaciones están asociadas a deterioro funcional y de la calidad de vida por lo que se consideran un factor cardinal de la enfermedad. En la literatura se ha descrito que las infecciones por bacterias y/o virus son las responsables del 78% de las exacerbaciones. Estos datos han sido descritos en poblaciones diferentes y no hay datos en la literatura que muestren cual es la epidemiología local de las exacerbaciones de EPOC y menos aún de aquellas que se asocian a consolidaciones neumónicas. Objetivo: Comparar la microbiología de las exacerbaciones severas de la EPOC que requieren ingreso a UCI con y sin infiltrados alveolares. Materiales y métodos: Estudio de corte transversal en el que se estudiaron pacientes con EPOC que ingresaron a la UCI Médica de la FCI-IC por exacerbación severa, asociada o no a infiltrados alveolares. Se tomaron muestras de microbiología, serológicas y radiografía de tórax para evaluar la etiología de la exacerbación, si se asocia a coinfección viral y a consolidación neumónica o no. Resultados: No se encontró una diferencia estadísticamente significativa en la microbiología de los diferentes grupos evaluados. Se encontró un resistencia global del 24% y llama la atención que hay una alta prevalencia de Serratia Marcescens AMPc entre los 2 grupos, germen que no está descrito como patógeno común en la literatura. Se encontraron diferencias en cuanto a factores de riesgo para presentar neumonía asociada como lo son un mayor índice de paquetes/año (55.1.6 vs. 36.3 paq/año, sig.=0.021). Así mismo se demostró que los pacientes con neumonía asociada presentan mayor necesidad de IOT (48.9 vs. 23.9, sig.=0.013). No hay diferencia significativa en desenlaces como mortalidad (20.5 vs. 13.0, sig.=0.346). Conclusiones: A pesar de no haber diferencia microbiológica entre los 2 grupos se encontraron variables como factores de riesgo y variables clínicas que pueden ayudar a proponer planes de manejo en los dos escenarios. El hecho de encontrar un paciente con neumonía asociada al cuadro de exacerbación no debe afectar en la toma de decisiones en relación al tratamiento antibiótico.

Effects of pulmonary rehabilitation program in a patient with severe asthma diagnosis

Objective: to present the effectiveness of pulmonary rehabilitation programs in the treatmentof a patient with asthma, this is the case of a young Caucasian girl —17 years old— with severe asthma diagnosis, with symptoms since she was eight years old, 10th grade student. Method: She was referred to the program of Pulmonary Rehabilitation after three hospitalizations during the last year due to asthmatic crises, dyspnoea in activities of daily living, and intolerance to physical exercise. In the initial evaluation, a patient with non-controlled asthma was found; she was receiving short-acting medication admitting that she was not complying with regular use and with a prescribed dose of the pharmacological treatment and that she ignored the importance of this commitment for optimal evolution. The patient expressed concern about the progressive deterioration at her respiratory and functional level during the last year and her fear and anxiety for not being able to breathe during activities befitting her age. Results: One month after receiving bronchodilators and long-acting steroids permanently and complying with recommendations about regular use and adequate inhalatory technique, the patient was included in a three-times a-week program of pulmonary rehabilitation during eight weeks for upper and lower extremity endurance and resistance training. Conclusion: This intervention showed significant changes in the patient at functional level and a greater social participation.

Quality of life and Chronic Obstructive Pulmonary Disease

The Chronic Obstructive Pulmonary Disease (COPD) has a progressive and irreversible character and it’s associated to the triad of dyspnea, exercise limitation and the evident deterioration of quality of life. In the United States the prevalence of COPD in adult population is approximately of 6% in men, and 1 to 3% in women and it’s the fourth cause of mortality by no transmissible chronic diseases. In 1993, the National Health Interview Surgery considered that 12 millions of Americans suffer from chronic bronchitis and 2 million had emphysema. These two affections are responsible for more than 13% of the hospitalizations. As this affection progresses, patients experience a diminution in quality of life related to health (CVRS), their capacity to work get worse and their participation in physical and social activities reduces. Nevertheless, it has been confirmed that the isolated evaluation of COPD seriousness, defined by the reduction of the Forced Expiratory Volume in the First Second (FEV1), does not provide enough information to know the health state perceived by the patients. The fact that the CVRS is the result of the interaction of multiple physical, psychological and social factors, unique for each individual, can explain this finding. This paper is a general and updated approach to the integral handling of patients with COPD, and it discusses the concept of quality of life, related to health improvement.

Description and analysis of pulmonary rehabilitation care programs current state in four cities of Colombia

Purpose: there are many studies reporting the benefits of pulmonary rehabilitation, but few of them exhibit the behavior and activities of these services. This article presents the characteristics of services, parts management and training level of team members, in addition to the variables or instruments used to measure the effectiveness and impact in these programs. Method: it was made a cross sectional convenience sample which included seven pulmonary rehabilitation services in four Colombian cities (Bogotá, Medellín, Manizales and Cali), selected by the coverage, for having at least one year of experience and for being formally established and recognized nationwide. The interdisciplinary team of each service answered a survey that was validated through a pilot test and expert consensus. Participation was voluntary. Results: labor onset pulmonary rehabilitation services correspond to an average of a decade, with COPD and asthma pathologies of attention. The programs are characterized by an outpatient treatment with an average duration of eight to twelve weeks, with a frequency of an hour three times a week. Also, the director of the service is regularly a pulmonologist and the coordinator a physiotherapist (57.14%). The posgradual training of these professionals is notable, and they report to have procedural, administrative and communicative skills, but qualify regular there research skills. The physical and technological resources are well tested. 71.42% have done impact studies, but only 28.57% have been published. All have in common training in upper limbs, lower limbs, respiratory muscles, counseling, functional assessment and quality of life. The effectiveness and impact of programs is measured by the walking test, quality of life questionnaires and activities of daily living.
