STUDY OBJECTIVES To compare the sensitivity and validity of mannitol, histamine, and cold air challenges to demonstrate the effect of inhaled corticosteroids (ICS) in asthma. DESIGN A prospective study. PARTICIPANTS Seventeen patients with recently diagnosed, steroid-naive asthma who fulfilled the diagnostic criteria of Finnish Social Insurance Institution and were hyperresponsive to both m...

Objective To investigate the occurrence of pneumonia and pneumonia related events in patients with chronic obstructive pulmonary disease (COPD) treated with two different fixed combinations of inhaled corticosteroid/long acting β2 agonist. DesignObservational retrospective pairwise cohort study matched (1:1) for propensity score. Setting Primary care medical records data linked to Swedish hospi...

BACKGROUND The combination of inhaled corticosteroids and long-acting inhaled beta(2)-adrenergic-agonists has become the standard therapy for many patients with moderate to severe persistent asthma. Whether the differences between budesonide/formoterol and fluticasone/salmeterol translate into differences in treatment outcomes in a real life setting is unknown. OBJECTIVES This study compared ...

The present authors evaluated adrenal reserve in asthmatic children on long-term inhaled corticosteroids and whether possible adrenal suppression could be predicted by growth retardation. Low-dose synacthen test (0.5 microg x 1.73 m(-2)) was performed in 72 asthmatic children with a median age of 9.4 (range 4.2-15.7) yrs on long-term treatment (median 18 (range 6-84) months) with low-to-moderat...

We investigated the effect of inhaled corticosteroids on the phenotypes and functional capacity of macrophages obtained by bronchoalveolar lavage from patients with pulmonary sarcoidosis. The results were correlated with clinical status and therapeutic efficacy. Ten symptomatic sarcoid patients (previously untreated) with radiological parenchymal shadowing and abnormal pulmonary function receiv...

UNLABELLED IL-5 is the primary cytokine that stimulates the production and survival of eosinophils and basophils from progenitor cells. The inhaled glucocorticoid, budesonide, has been shown to exert a therapeutic effect via suppression of eosinophil/basophil progenitors in vivo. Since various steroids have exhibited the ability to enhance eosinophil/basophil progenitor differentiation, we exam...

This 12-month dose-titration study assessed the effectiveness of budesonide/formoterol for maintenance plus relief with a control group using salmeterol/fluticasone for maintenance plus salbutamol for relief. Adolescents and adults (n = 2,143; mean forced expiratory volume in one second (FEV1) 73% predicted; mean inhaled corticosteroid (ICS) 884 microg.day(-1)) were randomised to budesonide/for...

We determined the effect of inhaled corticosteroid, budesonide, on the release of the anti-inflammatory cytokine, interleukin-10 (IL-10), and of pro-inflammatory cytokines, macrophage inflammatory protein-1 a (MIP-1 a ), interferong (IFNg ), and granulocyte-macrophage colony-stimulating factor (GM-CSF), from blood monocytes and alveolar macrophages of mild asthmatic subjects in a doubleblind, c...
