摘要:
Chronic obstructive pulmonary disease is a disease state characterized by the presence of airflow obstruction due to chronic bronchitis and/or emphysema. The airflow obstruction is generally progressive. In the past asthma was often confused with chronic obstructive pulmonary disease but as the cellular inflammatory mechanisms are quite different to chronic bronchitis and emphysema it is prudent to separate this condition of airway hyper-responsiveness.Exacerbation of chronic obstructive pulmonary disease is a considerable burden on health service resources in terms of morbidity and mortality. Approximately one half of exacerbations can be attributed to bacterial pathogens, the major pathogens beingHaemophilus influenzae,Streptococcus pnemoniaeandMoraxella catarrhalis. Resistance to common first-line treatment antibiotics such as the β-lactams can be variable. Newer fluoroquinolones such as grepafloxacin, levofloxacin, sparfloxacin, clinafloxacin, moxifloxacin, gatifloxacin and gemifloxacin are characterized by improved activity against Gram positive bacteria as well as their Gram negative properties. However, more randomized controlled trials need to be accomplished before the true role of quinolones in exacerbation of chronic obstructive pulmonary disease is clearly ascertained.
