BACKGROUND We hypothesized that asthma is preceded by a stage of recurrent episodes of wheezing during the first years of life and that inhaled corticosteroid therapy during symptomatic episodes in this early phase may delay progression to persistent wheezing. METHODS We assigned one-month-old infants to treatment with two-week courses of inhaled budesonide (400 mug per day) or placebo, initi...

BACKGROUND Ciclesonide is a new inhaled corticosteroids licensed for the prophylactic treatment of persistent asthma in adults. Currently beclomethasone dipropionate, budesonide and fluticasone propionate are the most commonly prescribed inhaled corticosteroids for the treatment of asthma but there has been no systematic review comparing the effectiveness and safety ciclesonide to these agents....

BACKGROUND Budesonide/formoterol (Symbicort) Maintenance and Reliever Therapy (SMART) is an effective asthma-management approach that treats symptoms with rapid increases in budesonide/formoterol. The cost-effectiveness of SMART vs higher fixed-dose budesonide/formoterol or salmeterol/fluticasone is unknown. METHODS This 6-month, double-blind study randomized patients with asthma uncontrolled...

BACKGROUND AND PURPOSE Inhaled corticosteroids (ICS) are the cornerstone of asthma pharmacotherapy and, acting via the glucocorticoid receptor (GR), reduce inflammatory gene expression. While this is often attributed to a direct inhibitory effect of the GR on inflammatory gene transcription, corticosteroids also induce the expression of anti-inflammatory genes in vitro. As there are no data to ...

BACKGROUND Increased arginase activity in the airways induces reduced bioavailability of L-arginine and cause deficiency of bronchodilatating and anti-inflammatory nitric oxide (NO). Therefore, arginine and arginase inhibitors may have therapeutic potential in the treatment of asthma. Using a murine model of asthma, we aimed to investigate the effects of inhaled L-arginine and arginase inhibito...

BACKGROUND The increased use of inhaled corticosteroids in the management of asthma raises concern about the safety of these drugs in children. We sought to determine the safety of long-term administration of inhaled budesonide in young children with asthma. METHODS We studied 15 children 2 to 7 years old who had severe perennial asthma. They inhaled 100 micrograms of budesonide twice daily f...

increased arginase activity in the airways decreases l-arginine and causes deficiency of bronchodilating and anti-inflammatory nitric oxide (no) in asthma. as, it is suggested that l-arginine may have therapeutic potential in asthma treatment, we aimed to investigate the effects of inhaled l-arginine on oxygen saturation (sao₂) and airway histology in a murine model of acute asthma. twenty eigh...

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, double-blind inhaled Steroid Treatment As Regu...

Because additive effects of inhaled corticosteroids and long-acting anticholinergics are unclear, we undertook this study to compare the efficacy of tiotropium alone and tiotropium plus budesonide in patients with chronic obstructive pulmonary disease. The study subjects were randomized to receive either tiotropium 18 microg once daily with or without budesonide 200 microg twice daily for 6 wee...

Eosinophilic bronchitis is a common cause of chronic cough, characterized by sputum eosinophilia similar to that seen in asthma, but unlike asthma the patients have no objective evidence of variable airflow obstruction or airway hyperresponsiveness. The reason for the different functional associations is unclear. The authors have tested the hypothesis that in eosinophilic bronchitis the inflamm...
