Mild Persistent Asthma (mild + persistent_asthma)
Selected AbstractsEvaluation of the Asthma Life Quality test for the screening and severity assessment of asthmaALLERGY, Issue 11 2004J. A. Fonseca Background:, Asthma Life Quality (ALQ) test, a 20-question questionnaire developed by the American College of Allergy, Asthma and Immunology, has been shown to be useful for asthma diagnosis. We aimed to determine the relation between ALQ scores and (a) diagnosis of asthma; (b) physician's classification of asthma severity according to National Institutes of Health/Global Initiative for Asthma (GINA). Methods:, Standard translation and cultural adaptation to Portuguese was performed. Patients self-administered the ALQ in the waiting room; the attending allergist classified them, blindly for the test. The scores of nonasthmatics were compared with those of asthma patients. Asthma patients were analyzed in two severity groups: intermittent and mild persistent asthma (IMPA), and moderate and severe persistent asthma (MSPA); sensitivity, specificity, positive and negative predictive values were calculated and receiver operating characteristic curve plotted. Logistic regression analysis models were computed. Results:, From 283 patients, 237 tests were analyzed. Non-asthmatic patients ALQ scores (mean ± SD) were 6 ± 4 and, for asthmatics, 10 ± 5 [mean difference 4.6 (95%CI 3.3,5.9)]. The odds of positive diagnosis increased 1.27 times (95%CI 1.17,1.38) for each one-unit increase in the test. For asthma severity ALQ scores were 9 ± 4 for IMPA, 15 ± 3 for MSPA [difference 6.0 (95%CI 4.8,7.1)]; with a sensitivity of 88% and specificity of 74% for a score of 12. The odds of MSPA increased 1.49 times (95%CI 1.28,1.74) per unit increase in ALQ. Conclusions:, ALQ can help both to identify patients with asthma and to differentiate those more likely to have moderate/severe asthma. These are relevant characteristics for the possible use of this simple, self-administered questionnaire in the assessment of asthma patients needing additional medical management. [source] Early intervention of recent onset mild persistent asthma in children aged under 11 yrs: the Steroid Treatment As Regular Therapy in early asthma (START) trialPEDIATRIC ALLERGY AND IMMUNOLOGY, Issue 2006Yu-Zhi Chen Inhaled corticosteroids are known to be effective in persistent asthma, but their long-term effect in mild persistent disease of recent onset, which is particularly relevant in children, requires clarification. The objective of this study was to determine the long-term efficacy of regular inhaled low-dose budesonide in children aged <11 yrs with mild persistent asthma with onset within 2 yrs of enrollment. Children aged 5,10 yrs formed part of the population of the inhaled Steroid Treatment As Regular Therapy in early asthma (START) study, and they were randomized in a double-blind manner to treatment with once daily budesonide 200 ,g or placebo via TurbuhalerTM in addition to usual clinical care and other asthma medication. The double-blind treatment phase continued for 3 yrs. Of the 1974 children, 1000 in the budesonide group and 974 in the placebo group, were analyzed for efficacy. Addition of once-daily budesonide to usual care was associated with a significant increase in the time to first severe asthma-related event (SARE) and significantly reduced risk of SARE over 3 yrs. The hazard ratio relative to usual care (placebo) was 0.60 (95% confidence interval: 0.40,0.90; p = 0.012), with a relative risk reduction of 40%. Children receiving budesonide also needed significantly less intervention with other inhaled corticosteroids (12.3% vs. 22.5% over 3 yrs; p < 0.01), with trends towards decreased usage of oral/systemic corticosteroids and inhaled short-acting ,2 -agonists. Budesonide treatment also had a significant beneficial effect on lung function relative to placebo. In conclusion, early intervention adding once-daily budesonide to usual care in children with mild, persistent asthma of recent onset reduces the long-term risk and frequency of SAREs and improves lung function compared with usual care alone. [source] Recommendations for treatment of intermittent mild persistent asthma in children and adolescentsPEDIATRIC PULMONOLOGY, Issue 3 2009Charles K. Naspitz MD Abstract Many parents and caretakers of children and adolescents with mild persistent asthma (MPA) do not follow proposed guidelines, namely the daily and continuous administration of inhaled corticosteroids (ICS). Instead, parents and caretakers tend to use ICS and bronchodilators intermittently for short periods and restart such therapy only when symptoms reappear. It is our opinion that intermittent treatment of MPA in children and adolescents might achieve the same level of asthma control as has been achieved in adults. We propose, therefore, that after an initial period of stabilization with age-appropriate doses of oral glucocorticoids or high-dose ICS and short-acting beta-2 agonists (SABA), caretakers can stop treatment once there are no longer signs or symptoms of asthma. When asthmatic symptoms recur, treatment should be restarted with ICS and SABA, or oral corticosteroids if the exacerbation is severe. The perception of developing asthma symptoms remains an unsolved problem. Based on our clinical experience in children and adolescents with asthma, we list a number of signs and symptoms that precede an exacerbation of asthma, allowing for an early re-introduction of treatment to prevent an exacerbation.

[source] Suppression of plasma matrix metalloproteinase-9 following montelukast treatment in childhood asthmaPEDIATRICS INTERNATIONAL, Issue 6 2007SHIH-SUNG CHUANG Abstract Background: Montelukast and ketotifen are commonly prescribed anti-inflammatory medications used in the treatment of childhood asthma. Methods: To investigate the modulation effect of montelukast and ketotifen, the levels of exhaled nitric oxide (eNO) and plasma matrix metalloproteinase-9 (MMP-9) were analyzed in a group of 30 children with mild persistent asthma. Results: Patients on montelukast therapy for 8 weeks had significantly decreased levels of eNO and plasma MMP-9, which were associated with improved symptoms and enhanced peak expiratory flow but not significantly associated with increased level of tissue inhibitor metalloproteinase-1 (TIMP-1). In contrast, treatment with ketotifen produced no significant changes in these parameters until 4,6 weeks into the therapy and no effect on plasma MMP-9. Conclusion: Leukotriene antagonists, such as montelukast, may be better non-steroidal anti-inflammatory drugs for preventing airway inflammation in mild childhood asthma. [source] Effectiveness of early budesonide intervention in Caucasian versus Asian patients with asthma: 3-year results of the START studyRESPIROLOGY, Issue 6 2006Wan C. TAN Objective and background: Few studies have assessed the effectiveness of inhaled corticosteroid therapy exclusively in Asian patients with asthma. The present analysis compared the efficacy of early intervention with inhaled budesonide in Caucasian and Asian patients over the first 3 years of the inhaled Steroid Treatment As Regular Therapy in early asthma study. Methods: Patients aged 5,66 years with mild persistent asthma of ,2 years' duration were randomized to 3 years of double-blind treatment with once-daily budesonide 200 µg (for patients aged <11 years) or 400 µg administered via Turbuhaler or placebo, plus usual asthma therapy. Results: Budesonide significantly improved asthma outcomes in both Caucasian (n = 4661) and Asian (n = 1995) patients compared with reference therapy (placebo plus usual asthma therapy). Budesonide reduced the risk of a first severe asthma-related event by 42% and 49% in Caucasian and Asian patients, respectively, over the 3-year treatment period (P < 0.001 for both). Moreover, budesonide significantly increased symptom-free days, decreased nights with sleeping problems, improved pre- and postbronchodilator FEV1 and reduced the need for additional asthma medications of particular drug classes compared with reference therapy. Except for differences in the patterns of use of additional asthma medications, outcomes with budesonide and overall adverse events were similar in the Caucasian and Asian patient populations. Conclusion: Inhaled budesonide administered once daily in Asian patients with recent-onset, mild persistent asthma significantly improved asthma control and pulmonary function compared with reference therapy. Moreover, this effectiveness paralleled that observed in Caucasian patients. [source] | |||||||||||||||||||
