title: [Continuous high-dose corticosteroid pressured aerosol therapy in steroid-dependent asthma].
abstract: Two therapeutic trials aimed at determining whether a high-dose inhaled corticosteroid, beclomethasone dipropionate (BDP), could reduce or suppress a long term and continuous treatment with a systemic corticosteroid, triamcinolone acetonide (TA), were carried out in a homogeneous population of severe, steroid-dependent asthmatics. The first one was a controlled, double-blind versus placebo trial involving 25 patients followed up for 5 months. The second one was an open trial involving 105 patients followed up for 12 months. In both trials the mean doses of TA were reduced by 60 to 65 per cent, and TA could be totally or nearly totally suppressed in almost 60 per cent of the cases with clinical and functional results that were equal or superior to those previously obtained with systemic corticosteroid therapy. It is concluded that: (a) continuous systemic corticosteroid therapy in mean doses of more than 5 mg/day of prednisone equivalent is now rarely indicated in patients with steroid-dependent asthma, and (b) inhaled corticosteroid therapy with BDP could be extended to cases of non steroid-dependent asthma inadequately controlled by bronchodilators.
