Nocturnal deaths among patients with chronic bronchitis and enphysema. As neutrophil degranulation is associated with bacterial infection, purulent sputum at exacerbation has been shown to be a marker of bacterial infection, defined by quantitative cultures of sputum as epkc as bronchoscopic protected specimen brush specimens Stockley et al ; Soler et al The effect of sleep loss on breathing in chronic obstructive pulmonary disease.

These and other mediators likely cause the systemic manifestations of exacerbations, including fatigue and in some instances fever. Antibiotics in the treatment of exacerbations The role and choice of antibiotics in the treatment of exacerbations has been anthohisen matter of controversy. In addition to the risk factors described above, experience in other respiratory infections tells us that recent antibiotic use, within the past 3 months, places the patient in a high risk group for harboring antibiotic resistant pathogens and therefore having a poor outcome.

It is likely that acquisition of these pathogens in a patient with COPD, because ajthonisen compromised lung defense, allows establishment of infection in the lower respiratory tract, with or without overt clinical manifestations. This immune response, in combination with appropriate antibiotics, is able to eliminate or control proliferation of the infecting bacteria. In this time period, the primary outcomes were the rate of repeat exacerbations, hospitalizations for respiratory disease and health-related quality of life measures.

Sleep, 19pp. Prediction of oxygenation during sleep in patients with chronic obstructive lung disease. Acute exacerbations of COPD: Proc Am Thorac Soc. Interestingly, anghonisen classification was not designed to be a classification of severity of exacerbations, but has dpoc so over time.

Optimizing antibiotic selection in treating COPD exacerbations

Pathogenesis of infectious exacerbations Our understanding of acute exacerbation pathogenesis, especially in relation to bacterial infection, has seen significant progress over the last few years. Value of C-reactive protein measurements in exacerbations of chronic obstructive pulmonary disease. Abstract Our understanding of the etiology, pathogenesis and consequences of acute exacerbations of chronic obstructive pulmonary disease COPD has increased substantially in the last decade.

A unique feature of this study was the measurement of primary outcome at anthonsien days, instead of the traditional 2—3 weeks. Two recent antibiotic comparison trials were designed to show differences among antibiotics and measured some unconventional but clinically relevant end-points.

Among the risk factors for poor outcome identified in various studies are increasing age, severity of underlying airway obstruction, presence of co-morbid illnesses especially cardiac diseasea history of recurrent exacerbations, use of home oxygen, use of chronic steroids, hypercapnia and acute bronchodilator use Ball et al ; Adams et al ; Dewan et al ; Miravitlles et al ; Groenewegen et al ; Wilson et al Acute exacerbations of chronic obstructive pulmonary disease are accompanied by elevations of plasma fibrinogen and serum IL-6 levels.

Pathogenesis of bacterial exacerbations of COPD. Standards for the diagnosis and treatment of patients with COPD: Other important clinical goals of treatment include delaying the next exacerbation, prevention of early relapse and more rapid resolution of symptoms Anzueto et al ; Miravitlles et al ; Aaron et al In the second analysis, 11 trials were included, and a much larger beneficial effect on mortality and prevention of clinical failure was demonstrated, especially in moderate to severe exacerbations Ram et al The need for chest roentgenograms in adults with acute respiratory illness.

The Anthonisen definition is based on the presence of one or more of three cardinal symptoms, including an increase or new onset of dyspnea, sputum production and sputum purulence Anthonisen et al Certain shared characteristics of these pathogens provide clues to their predilection for causing infections in COPD.

Pathogenesis of exacerbations The emerging concept that an increase in airway inflammation from the baseline level characteristic of COPD is central to the pathogenesis of acute exacerbations is supported by several recent studies White et al ; Sethi a. Similarly, exacerbations are in many instances induced by infection, therefore eradication of the offending infectious pathogen should be a goal of treatment.

This trial had several unique design features which relate to observations made in this study. Further studies are required to elucidate the role of physiopathological alterations during sleep, the importance of nocturnal desaturations and the role of oxygen therapy and ventilatory support, as well as the utility of some drugs that could improve sleep quality and gas exchange in these patients.

Effects of zolpiden and triazolan on sleep and respiration in mild to moderate chronic obstructive pulmonary disease. However, in the multitude of anfhonisen comparison trials, the choice of antibiotics does not appear to affect the clinical outcome, which can be explained by several methodological limitations of these trials.

The pathogenesis of exacerbations with atypical bacterial infection is poorly understood. These exacerbations are a major driver for office visits, hospitalizations and therefore cost of care in COPD.
