title: [Efficacy of nebulized budesonide in severe exacerbation of bronchial asthma].
abstract: The study was undertaken to examine the clinical effectiveness of nebulizer inhalations of budesonide suspension during severe attacks of bronchial asthma (BA) and the possibility of its use versus systemic glucocorticosteroids (GCSs). Sixty-eight patients admitted for a severe attack of BA were examined. The forced expiratory volume per sec (FEV1) was less than 40% and the peak forced expiration rate (PFER) was less than 150 l/min. First-line therapy included inhaled salbutamol (5-10 mg within 1.5-2 hours), oxygen, and intravenous prednisolone (120 mg). Thirty-two patients showed a good response to first-line therapy (a more than 50% increase in FEV1) as compared with the normal values) (Group 1) and 36 patients with concurrent obstructive lung disease (COLD) had an inadequate response (FEV1 was less than 40% of the normal values) was found in 32 patients (Group 2). Then the patients were randomized: 16 patients from Group 1 took budesonide, 4 mg/day, the other 16 received intravenous prednisolone, 120 mg/day. In Group 2, the efficacy of the drug added to therapy with oral prednisolone, 30 mg/day, was evaluated: 18 patients were given budesonide, 4 mg/day, and 18 received placebo. In patients with a good response to primary therapy, positive clinical and functional changes were found on day 6 of treatment. Group 2 patients receiving budesonide showed a significantly (p < 0.05) more marked positive changes in BA symptoms, FEV1, and PFER, which allowed a course of therapy with systemic GCSs to be reduced. Nebulized budesonide may be used instead of systemic GCSs to treat exacerbated BA if there is a good clinical and functional response to first-line broncholytic therapy, which is indicative of successful abatement of bronchospasm. If there is a poor response to first-line therapy in patients with more severe BA concurrent COLD, the early use of budesonide suspension in addition to systemic GCSs may enhance the efficiency of therapy for BA attacks and reduce the volume of systemic steroidal therapy.
