Corticosteroids in chronic bronchitis and pulmonary emphysema.
Chronic bronchitis and emphysema (chronic obstructive pulmonary disease [COPD]) represent a major health problem in this country. Corticosteroids have provided an important advance in the management of bronchial asthma, but the role of these drugs in the therapy for COPD has not been defined clearly. To gain further insight into this problem, an overview of the pharmacologic properties and mechanisms of action of corticosteroids on the cellular systems of the lung and a critical analysis of the 17 studies evaluating the efficacy of therapy with corticosteroids in COPD were done. There are several theoretic reasons why corticosteroids might be useful in treating COPD; however the majority of studies have not demonstrated a positive effect, yet individual patients have attained marked improvement. An objectively monitored, finite trial of therapy with corticosteroids in the patient with COPD who has worsening symptoms is warranted, as the benefit is high in responsive individuals and the risk is low in nonresponders.
