The response to glucocorticoids (GCs) therapy classifies severe refractory asthma (SRA) and mild asthma, so the glucocorticoid receptors (GCRs) gene expression may be involved in SRA pathogenesis. Thus, it is aimed to compare the expression levels of two GCR isoforms (GCRα and GCRβ) in SRA, mild asthmatics, and healthy controls. Total RNA was isolated from the peripheral blood mononuclear lymph...
theophylline, (1,3-dimethylxanthine) is widely used as a smooth muscle relaxant, myocardial stimulant and a diuretic agent. the most frequent use of theophylline is in treatment of acute and chronic asthma as a bronchodilator. to determine the effect of theophylline on serum electrolyte and uric acid, 21 asthmatic children (age range 1,5-7 years) with severe acute asthma and 25 patients with ch...
allergic asthma is the most common acute inflammatory airway disorder and their incidence population has exploded in the last years, being estimated that over 300 million people worldwide have the condition. here, we present a brief overview of relationship of allergic asthma with diet and food intake. several studies have shown that most asthma cases are due to an allergic immune response to e...
Near-fatal asthma (NFA) is described as acute asthma associated with a respiratory arrest or arterial carbon dioxide tension greater than 50 mmHg, with or without altered consciousness, requiring mechanical ventilation. Risk factors for near fatal asthma have not been fully elucidated. In 80-85% of all fatal events, a phenotype, characterized by eosinophilic inflammation associated with gradual...
BACKGROUND Secretory phospholipases A2 (sPLA2) have functions relevant to asthmatic inflammation, including eicosanoid synthesis and effects on dendritic cells and T cells. The aim of this study was to measure sPLA2 activity in patients with stable and acute asthma and to assess potential associations with body mass index (BMI), and plasma cholesterol and vitamin C concentrations. METHODS Pla...
Fifty-two patients admitted to hospital with acute severe asthma took part in a prospective study investigating the rate and pattern of their subsequent recovery. Clinical assessment of the severity of the acute attack on admission (according to pulse rate, degree of pulsus paradoxus, and peak expiratory flow rate) did not reliably predict the results of arterial blood gas analysis. Subjects we...
