초록
연구배경: 경구 및 주사용 스테로이드 제제는 기관지 천식 치료제로서 중요한 역할을 하여 왔으나 그 부작용 때문에 사용이 제한되어, 근래에는 부작용이 적은 흡입성 스테로이드제제인 Beclomethasone dipropionate나 Budesonide 등이 개발되어 사용되고 있다. 본 연구에서는 기관지 천식 환자와 만성 폐쇄성 폐질환 환자에서 흡입성 스테로이드 제제인 Beclomethasone과 Budesonide을 투여하여 투여하여 용량과 투여방법에 따라 기저 코르티솔 농도에 미치는 영향에 대해서 연구하였다. 방법: 대상은 1989년 3월부터 1994년 2월까지 전북대학교 병원 내과에 입원해 치료받은 44명으로 흡입성 스테로이드 제제를 투여하기전 10일 동안은 어떠한 종류의 스테로이드도 복용하지 않도록 한후 12일 동안
Background: Topical inhaled steroids, budesonide(Bu) and beclomethasone dipropionate (BOP), are now established as effective drugs in the management of chronic asthma. These drugs have high topical anti-inflammatory effect with low systemic activity. This study was performed to determine the effects of two inhaled corticosteroids, Bu and BOP, on the adrenocortical supression in 44 patients with bronchial asthma or chronic obstructive pulmonary disease. Methods: The adrenocortical function was assessed by measurement of serum cortisol concentration at 8 o'clock in morning and free cortisol in 24-hour urine collection at interval in 44 patients. No steroid was administered during the pretreatment period of 10 days and the final 6 days of the study. Each subject inhaled BOP or Bu, in daily doses of 800 or 1,600 micrograms for 12 days. The dose was delivered by metered dose inhaler (MDI) or diskhaler or large spacing device attached to MDI. Results: The levels of serum cortisol and 24-hour urinary free cortisol were decreased during the treatment period in patients inhaled Bu delivered by MDI in daily doses of 800 and 1,600 micrograms. In contrast, serum cortisol level was decreased on 6 and 12th day of treatment period in patients with BDP diskhaler in daily doses of 800 micrograms. In daily doses of 1,600 micrograms, the serum cortisol and 24hour urine free cortisol levels were decreased on 6, 9 and 12th day of treatment period in patients with BDP disk haler. The serum cortisol and 24-hour urinary free cortisol levels were not significantly decreased during the treatment period in patients inhaled Bu delivered by large spacing device attached to a MDI. Conclusion: These results showed that 1) the endogenous cortisol secretion was suppressed after inhalation of BDP and Bu in daily doses of 800 and 1,600micrograms, 2) Bu with MDI suppressed the adrenocortical function more than BDP with diskhaler, in daily doses of 1600 micrograms. and 3)large spacing device attached to a MDI might decrease the risk of suppression in the hypothalamic -pituitary- adrenal axis.
