BACKGROUND Although inhaled glucocorticosteroids are recommended for persistent asthma, their long-term effect on recent onset, mild, persistent asthma has yet to be established. METHODS We did a randomised, double-blind clinical trial in 7241 patients in 32 countries to assess the effects of budesonide in patients who had had mild persistent asthma for(More)
In most clinical trials, some patients do not complete their intended follow-up according to protocol, for a variety of reasons, and are often described as having 'dropped out' before the conclusion of the trial. Their subsequent measurements are missing, and this makes the analysis of the trial's repeated measures data more difficult. In this paper we(More)
BACKGROUND The Inhaled Steroid as Regular Therapy in Early Asthma (START) study reported that early intervention with budesonide in mild persistent asthma reduces severe asthmatic events and improves symptom outcomes and lung function in adults and children. OBJECTIVE We sought to estimate the incremental cost-effectiveness of early intervention with(More)
STUDY OBJECTIVES Asthmatic patients lose lung function faster than normal subjects. The effectiveness of early intervention with inhaled corticosteroids on this decline in lung function is not established in recent-onset disease. DESIGN The Inhaled Steroid Treatment as Regular Therapy in Early Asthma study was a randomized, double-blind study in 7,165(More)
BACKGROUND Previous studies have suggested a reduced benefit from therapy with inhaled corticosteroids (ICSs) in asthmatic patients who smoke. The objective of this post hoc study was to study the effects of low-dose inhaled budesonide on lung function in smokers and nonsmokers with mild persistent asthma. METHODS Adult patients (age, >or= 18 years) in(More)
Various ways of expressing rhinomanometric results have been an obstacle for exchange of information. A method that could be generally accepted must: 1) easily give the clinician an informative figure describing the nasal airway patency in all cases: 2) provide a basis for statistical evaluation: and 3) allow a numerical description of the whole(More)
Early intervention with budesonide is an effective strategy for mild persistent asthma, which has been shown to provide additional clinical benefits at a low incremental cost using USA cost data. The present authors analysed whether this strategy would be cost-effective using cost data for other countries. Based on the 3-yr prospective, randomised,(More)
OBJECTIVE AND BACKGROUND Few studies have assessed the effectiveness of inhaled corticosteroid therapy exclusively in Asian patients with asthma. The present analysis compared the efficacy of early intervention with inhaled budesonide in Caucasian and Asian patients over the first 3 years of the inhaled Steroid Treatment As Regular Therapy in early asthma(More)
A stochastic model of Feulgen hydrolysis is proposed. The model, constructed so as to embody the main features of chromatin structure, is simple enough to allow the calculation of extraction rates. Extraction rate curves generated by the model are compared with experimental curves obtained under various conditions (different fixatives and hydrolysis(More)
Theophylline (1, 3-dimethylxanthine) and enprofylline (3-propylxanthine) have been examined for effects in the rat. Enprofylline was 3.8 times as potent as theophylline as a tracheal relaxant in vitro, and 1.3 times as potent as theophylline to increase the rate of isolated perfused hearts. An oral dose (5 mg/kg) of enprofylline to rats was almost(More)
