To determine whether protein levels of interleukin-5 (IL-5) in induced sputum reflect the degree of eosinophilic inflammation, we evaluated the role of IL-5 on clinical characteristics in stable asthmatic patients. IL-5 level, differential eosinophil count, and level of eosinophil cationic protein (ECP) in induced sputum were all significantly higher for asthmatics than for normal controls. ⋯ However, we found no significant difference in IL-5 levels between atopic and nonatopic asthmatics. IL-5 level in induced sputum is a good indicator of eosinophilic inflammation in atopic and nonatopic asthmatic patients.

Randomized Controlled Trial Clinical Trial
Symptomatic improvement following emergency department management of asthma: a pilot study of intramuscular dexamethasone versus oral prednisone.
Systemic corticosteroid therapy is an established adjunct to beta-adrenergic medications in acute exacerbations of asthma. To date, no study has defined the role of long-acting intramuscular preparations of corticosteroids in pediatric patients with asthma. A pilot study was conducted to prospectively compare symptomatic improvement following a single injection of intramuscular dexamethasone (IMD) to a 3-day regimen of oral prednisone (OP) for children with mild to moderate wheezing episodes that are responsive to nebulized medications in the Pediatric Emergency Department (PED). ⋯ None of the study patients were hospitalized during the follow-up period, and all reported symptomatic improvement since initial treatment. The data of this pilot study suggest that IMD may be a feasible alternative to OP for treatment of acute wheezing episodes in children with asthma. IMD provides sufficient treatment to prevent clinical deterioration within 5 days after initial therapy for mild to moderate pediatric exacerbations of asthma that are responsive to nebulized medications.

Randomized Controlled Trial Clinical Trial
Treatment of nocturnal asthma by addition of oral slow-release albuterol to standard treatment in stable asthma patients.
Nocturnal and early-morning complaints in asthma patients are sometimes difficult to treat. We investigated the efficacy of an oral osmotically controlled release (OR) formulation of albuterol 8 mg in 35 patients with stable asthma and nocturnal complaints and/or morning dipping of the peak expiratory flow (PEF). The mean age was 45 years (range 22-70), the FEV(1) was 61 +/- 20% of predicted, and inhaled steroids were used by 32 patients. ⋯ Mental fitness was improved, but significantly only in the morning. We concluded that additional treatment with albuterol 8 mg OR once or twice daily did not lead to an overall clinical improvement in this group of patients with nocturnal asthma during standard treatment. In view of the tendency to improvement, it may be worth trying this treatment in individual patients.

The aim of this study was to examine the potential differences between beliefs relating to symptomatic and preventive inhaler treatment and to analyze the relationship between these beliefs and the use of inhalers by adult patients with asthma in general practice. Unstructured interviews with a stratified sample of 8 patients, taking a combination of salbutamol and beclomethasone inhalers, were used to develop themes for a structured interview, where questions relating to 8 main areas of interest were measured on a 5-point Likert scale. Forty patients prescribed the same combination of inhalers were randomly selected for the structured interview. ⋯ There are important differences in the beliefs that patients hold in relation to symptomatic and preventive use of inhaler treatment. These findings suggest that focusing on very specific attitudes to treatment may be of benefit in the health education of adults with asthma. Further work is planned to refine the themes so that doctors will be able to explore patients' views about their inhaler treatment by asking a few direct questions.
