[A comparison of a 3 day course with a 2 week course of oral prednisolone in patients with chronic asthma].
To investigate an appropriate duration of short course of a oral prednisolone (PSL), we compare the results of a 3 day course of PSL (3D) with those of a 2 week course of PSL (2W) in 20 patients with chronic asthma. All subjects had been inhaling beclomethasone dipropionate (BDP, mean daily dose: 1325 micrograms), and had been self-monitoring their peak expiratory flow rate (PEF) for at least 6 months. Mean +/- SE of the best PSL-induced PEF in 2W (2W-best) was not different from that in 3D (397 +/- 29 and 356 +/- 23 L/min, respectively, p = 0.26). Mean weekly morning PEF/2W-best before and 1, 2, 3 and 4 weeks after PSL was 60, 76, 80, 76 and 76% in 2W, and 63, 73, 67, 67 and 65% in 3D, respectively. Both changes over the course of time were significant. The frequency of emergency room visits and/or unscheduled hospital visits was not significantly different between 2W and 3D. However, both the frequency of use of inhaled beta 2 agonists and the symptom score significantly decreased only in 2W. Seven patients (35%) did not need additional oral PSL during the 4-week period after initiating 3D, and among these patients, emergency room visits and/or unscheduled hospital visits were completely controlled. In conclusion, although the effect of 3D was inferior than that of 2W, it was a sufficient duration in 35% of the patients, and thus, may be appropriate as a initial duration of rescue course of oral steroids.
