Diagnostico Diferencial. No hay ninguna prueba de confirmación diagnóstica para exacerbación de EPOC. La evaluación del paciente con una posible exacerbación debe centrarse en la gravedad del episodio y excluir otras causas potenciales del deterioro clínico. Estas condiciones, que pueden agravar y / o imitar una exacerbación pueden incluir: Neumonía Neumotórax Cáncer Pulmonar Derrame Pleural Embolia Pulmonar Falla Cardiaca Arritmia Cardiaca Fractura Costal Obstrucción de vía aérea superior. Speaker Notes There is no confirmatory diagnostic test for an exacerbation of COPD. Evaluation of the patient with a possible exacerbation should focus on the severity of the episode and exclude other potential causes for the deterioration in symptoms. These may include: Pneumonia Pneumothorax Lung carcinoma Pleural effusion Pulmonary embolism Cardiac failure Cardiac arrhythmia Rib fracture Upper airway obstruction Reference Hurst JR, Wedzicha JA.

Exacerbaciones NO reportadas Las exacerbaciones de la EPOC no reportadas son comunes Se desconoce a corto o mediano plazo el impacto de estas en la calidad de vida El objetivo del estudio fue examinar el impacto de las exacerbaciones NO reportadas en la calidad de vida siguiendo por mas de 1 año a 491 pacientes con EPOC. Los pacientes fueron monitoreados mensualmente por 12 meses documentando síntomas-signos de exacerbación (al menos un síntoma en 48 hrs) Los pacientes se dividieron en 6 grupos: sin exacerbación, solo una exacerbación no reportada, mas de una exacerbación no reportada, solo una exacerbación reportada, mas de una exacerbación reportada y ambas: exacerbaciones reportadas y no reportadas Adapted from Xu W, et al. Eur Respir J. 2010;35:1022-1030
Exacerbaciones NO reportadas Se registraron 466 exacerbaciones reportadas y 410 no reportadas Al comparar los pacientes sin exacerbaciones frente a los pacientes con 1 sola exacerbación , el cambio en el en el cuestionario de calidad de vida de San Jorge (SGRQ) fue similar (significancia ajustada de 1.22 puntos), pero significativamente peor en los pacientes con mas de una exacerbación no reportada (4.61 puntos de significancia ajustada) Adapted from Xu W, et al.

Exacerbaciones no reportadas. Change from Baseline in SGRQ Versus Patients with No Exacerbations Worsening Speaker Notes Unreported COPD exacerbations are common, but their intermediate-to-long-term impacts on health-related quality of life are unknown. The aim of the present study was to examine the impact of unreported exacerbations on health-related quality of life over 1 year of follow-up in 491 COPD patients. Patients were monitored monthly for 12 months to document exacerbations (at least one symptom worsening for ≥48 hours). Patients were categorised into six groups: no exacerbation, one unreported exacerbation only, more than one unreported exacerbation only, one reported exacerbation only, more than one reported exacerbation only, and both unreported and reported exacerbations. A total of 466 unreported and 410 reported exacerbations were recorded. Compared with patients with no exacerbations, the change in SGRQ total score was similar amongst patients with one unreported exacerbation (adjusted mean change 1.22 points [95% CI -4.05-6.48]), but significantly worse among patients with more than one unreported exacerbation (4.61 [95% CI 0.09-9.13]).

Percent With ≥2 Exacerbations per Patient per Year Elevado riesgo de exacerbación asociado con tos y producción de esputo. * * P<0.0001 Percent With ≥2 Exacerbations per Patient per Year Speaker Notes This study was undertaken to identify features associated with chronic cough and sputum production in COPD subjects. Cross-sectional analysis of data were obtained in 433 COPD subjects with (n=321) and without (n=112) chronic cough and sputum production. Subjects with chronic cough and sputum production had increased total mean numbers of exacerbations per patient per year (2.20 versus 0.97, P<0.0001), moderate exacerbations (1.80 versus 0.66, P<0.0001), and severe exacerbations requiring hospitalisations (0.43 versus 0.22, P<0.02). Frequent exacerbations (two or more per patient per year) occurred in 55% versus 22% of subjects, respectively, with and without chronic cough and sputum production (P<0.0001).

Impacto de las exacerbaciones en EPOC. Paciente con exacerbaciones Frecuentes Mayor Mortalidad. Más Rápida caída de la función Pulmonar. Pobre Calidad de Vida Mayor Inflamación de la Vía Aérea Speaker Notes Patients with frequent exacerbations of COPD result in higher mortality, poorer QOL, increased airway inflammation, and a more rapid decline in lung function versus those with less frequent exacerbations. COPD exacerbations are associated with increased airway and systemic inflammation and physiological changes, especially the development of hyperinflation. They are triggered mainly by respiratory viruses and bacteria, which infect the lower airway and increase airway inflammation. Some patients are particularly susceptible to exacerbations, and show worse health status and faster disease progression than those who have infrequent exacerbations.

Daily Median PEFR as % Baseline La función Pulmonar Puede Recuperarse Lentamente después de una exacerbación. 101 N=91 Exacerbation 100 99 Daily Median PEFR as % Baseline 98 97 Speaker Notes Before onset of exacerbation there was deterioration in the symptoms of dyspnoea, sore throat, cough, and symptoms of a common cold (all P<0.05), but not lung function. Median recovery times were 6 days for peak expiratory flow rate (PEFR) and 7 days for daily total symptom score. Recovery of PEFR to baseline values was complete in only 75.2% of exacerbations at 35 days; whereas in 7.1% of exacerbations at 91 days PEFR recovery had not occurred. In the 404 exacerbations where recovery of PEFR to baseline values was complete at 91 days, increased dyspnoea and colds at onset of exacerbation were associated with prolonged recovery times (P<0.001). The declines in lung function, whether measured by PEFR, FEV1, or FVC, were all highly significant (P<0.001). Reference Seemungal TA, Donaldson GC, Bhowmik A, Jeffries DJ, Wedzicha JA.

Multivariate techniques were used to analyse the prognostic influence of acute exacerbations of COPD treated in hospital (visits to the emergency service and admissions), patient age, smoking, body mass index, comorbidity, long term oxygen therapy, forced spirometric parameters, and arterial blood gas tensions in a prospective cohort of 304 men with COPD followed up for 5 years. Only older age, arterial carbon dioxide tension, and acute exacerbations of COPD were found to be independent indicators of a poor prognosis. The patients with the greatest mortality risk were those with three or more acute COPD exacerbations.

Inflamación Pulmonar y sistémica en la exacerbación TRIGGERS Viruses Bacteria Pollutants EFFECTS Inflamed COPD airway Greater airway inflammation Speaker Notes COPD exacerbations are associated with increased upper and lower airway and systemic inflammation. The airway inflammatory responses cause oedema, bronchospasm, and increased sputum production, leading to worsening airflow limitation and development of dynamic hyperinflation, which is a main cause of dyspnoea, the most common symptom of an exacerbation. Systemic inflammation increases at exacerbation and, although the causes of this response in COPD are not clear, there is probably a spill-over of inflammatory markers from the lungs.

Human rhinovirus is the dominant viral pathogen. Newly emerging viruses, such as human metapneumoviruses, may also be important, because in 10 to 15% of acute respiratory illness no pathogen can be detected despite PCR.1 Traditional virological techniques have reported rates of viral detection up to 20%. More recently, studies using polymerase chain reaction (PCR) of nasal aspirates during acute exacerbation identified infection rates of 39%. 1 The predominant bacteria isolated from sputum samples in COPD exacerbations are noncapsulated Haemophilus influenzae, Moraxella catarrhalis, and Streptococcus pneumoniae. 1 In patients with more severe exacerbations who required mechanical ventilation, Pseudomonas aeruginosa and gram-negative bacilli are also recognised. 1 Bacteria are associated with 50% of exacerbations and have been shown to enhance pulmonary inflammation, induce mucus hypersecretion, and reduce ciliary beat frequency in vitro. 1 References 1.

The study included 91 patients with exacerbations, quantitative sputum culture was performed, and bacterial growth was considered significant only when the organism was isolated at concentrations >106 cfu/mL (>105 cfu/mL for Streptococcus pneumoniae) in samples with <10 epithelial cells and >25 leukocytes per low magnification field (x 100). Bacteria isolated included Haemophilus influenzae (22%), Pseudomonas aeruginosa (15%), S pneumoniae (10%), Moraxella catarrhalis (9%), other Gram-negative bacteria (7%), and non-potentially pathogenic microorganisms (non-PPMs, 36%). P aeruginosa and H influenzae were isolated more frequently among the patients with FEV1 <50% than among those with FEV1 >50% (P<0.05). All patients with P aeruginosa in sputum had FEV1 <1,700 mL. FEV1 <50% was associated with a very high risk of P aeruginosa or H influenzae isolation (odds ratios = 6.62, 95% CI = 1.2 to 123.6; and 6.85, 95% CI = 1.6 to 52.6; respectively).

Lung function tests revealed an FEV1 of ≥50% of the predicted value in 30 patients (stage I), an FEV1 of 35% to <50% of the predicted value in 30 patients (stage II), and an FEV1 of ≤35% of the predicted value in 34 patients (stage III). Bacteria were classified into three groups: group 1 contained S pneumoniae and other Gram-positive cocci; group 2, H influenzae and M catarrhalis; and group 3, Enterobacteriaceae and Pseudomonas spp. For all patients together, the most frequently isolated bacteria were group 3 organisms (48.2%), followed by group 1 organisms (30.4%), and group 2 organisms (21.4%). In stage I patients, 14 of 30 had bacteria from group 1, seven of 30 had group 2, and nine of 30 had group 3. In stage II patients, eight of 30 had group 1 bacteria, 10 of 30 had group 2, and 12 of 30 had group 3. In stage III patients, 12 of 52 had group 1 bacteria, seven of 52 had group 2, and 22 of 52 had group 3. The three groups of bacteria causing infective exacerbations were unevenly distributed among the three severity stages of lung function (P=0.016).

Como Prevenir las E-EPOC?
Vacunación de Influenza : Riesgo para Cualquier Exacerbación. Los resultados de los ensayos clínicos aleatorios indican que la vacuna antigripal inactivada disminuye las exacerbaciones en pacientes con EPOC. La reducción en las exacerbaciones ocurren tres o más semanas después de la vacunación. Hay un leve aumento de efectos adversos locales transitorios con la vacunación, pero no hay evidencia de un aumento de las exacerbaciones a corto plazo. Speaker Notes Influenza vaccinations are currently recommended in the care of people with COPD, but these recommendations are based largely on evidence from observational studies with very few randomised controlled trials (RCTs) reported. Eleven trials were included but only six of these were specifically performed in COPD patients. The others were conducted on elderly and high-risk individuals, some of whom had chronic lung disease. Inactivated vaccine in COPD patients resulted in a significant reduction in the total number of exacerbations per vaccinated subject compared with those who received placebo (P=0.006). This was due to the reduction in "late" exacerbations occurring after 3 or 4 weeks (P=0.0004). Meta-analysis indicates that inactivated vaccine reduces exacerbations in COPD patients. The size of effect was similar to that seen in large observational studies, and was due to a reduction in exacerbations occurring three or more weeks after vaccination, and due to influenza. There is a mild increase in transient local adverse effects with vaccination, but no evidence of an increase in early exacerbations. Reference Poole PJ, Chacko E, Wood-Baker RW, Cates CJ.

Patients were stratified according to smoking status and treatment with LABAs. Treatment with ICS was stopped at the beginning of the study. Data from the two studies were analysed separately and in a pooled analysis.1 Approximately 50% of patients in the two 12-month studies continued to use LABAs throughout the roflumilast treatment period.1 Roflumilast reduced the rate of exacerbations irrespective of whether patients were taking concomitant COPD maintenance therapy.1 A pre-specified analysis of the effects of roflumilast in the LABA subgroup, revealed approximately 21% lower exacerbation rate in patients receiving roflumilast relative to placebo (P=0.0011).2 References 1.
