BACKGROUND Patients with mild asthma frequently have only exercise-induced bronchoconstriction, a symptom of inadequate control of asthma. We evaluated the ability of montelukast, a leukotriene-receptor antagonist, to protect such patients against exercise-induced bronchoconstriction. METHODS We randomly assigned 110 patients (age, 15 to 45 years) with(More)
Complementary-alternative medicines are extensively used in the treatment of allergic rhinitis and asthma, but evidence-based recommendations are lacking. To provide evidence-based recommendations, the literature was searched by using MedLine and the Cochrane Library to March 2005 (Key words: Asthma [OR] Rhinitis, [AND] Complementary [OR] Alternative(More)
Five lipoxygenase (5-LO) is the first committed enzyme in the metabolic pathway leading to the synthesis of the leukotrienes. We examined genomic DNA isolated from 25 normal subjects and 31 patients with asthma (6 of whom had aspirin-sensitive asthma) for mutations in the known transcription factor binding regions and the protein encoding region of the 5-LO(More)
OBJECTIVE To evaluate the effectiveness of inhibiting the formation of the 5-lipoxygenase products of arachidonic acid by the 5-lipoxygenase inhibitor zileuton in the treatment of mild-to-moderate asthma. DESIGN Randomized, double-blind, placebo-controlled study. SETTING University hospitals and private allergy and pulmonary practices. PATIENTS A(More)
The aim of the present study was to examine the effect of creatine supplementation (CrS) on sprint exercise performance and skeletal muscle anaerobic metabolism during and after sprint exercise. Eight active, untrained men performed a 20-s maximal sprint on an air-braked cycle ergometer after 5 days of CrS [30 g creatine (Cr) + 30 g dextrose per day] or(More)
OBJECTIVE To determine whether montelukast, a leukotriene receptor antagonist, attenuates exercise-induced bronchoconstriction (EIB) in 6- to 14-year-old children with asthma. STUDY DESIGN Double-blind, multicenter, 2-period crossover study. Children (n = 27) with forced expiratory volume in 1 second (FEV1) > or =70% of the predicted value and a fall in(More)
The efficacy of the oral leukotriene-receptor antagonist zafirlukast was assessed as maintenance therapy for patients with mild-to-moderate asthma. A total of 762 patients aged 12 to 76 years were enrolled in a 13-week, multicenter, double-masked, placebo-controlled, parallel-group trial and randomly assigned to receive either zafirlukast (20 mg twice(More)
The currently available beclomethasone dipropionate (BDP) metered-dose nasal aerosol spray is considered uncomfortable by some patients because of the force of delivery. It was compared for efficacy and acceptability in a double-blind study with a new aqueous suspension BDP spray for the treatment of seasonal allergic rhinitis in 44 symptomatic patients(More)
BACKGROUND Inhaled glucocorticosteroids (GCS) are the most effective long-term controller medications for the treatment of persistent asthma. Currently, however, available delivery devices limit their use in young children. A nebulized formulation of budesonide has been developed to address the needs of infants and young children. OBJECTIVE To evaluate(More)
