More evidence is needed on which to base recommendations for treatment of mild-moderate persistent asthma in school-aged children.
                The Pediatric Asthma Controller Trial (PACT) compared the effectiveness of 3 regimens in achieving asthma control.
                A total of 285 children (ages 6-14 years) with mild-moderate persistent asthma on the basis of symptoms, and with FEV(1) >or= 80% predicted and methacholine FEV(1) PC(20) <or= 12.5 mg/mL, were randomized to 1 of 3 double-blind 48-week treatments: fluticasone 100 microg twice daily (fluticasone monotherapy), fluticasone 100 microg/salmeterol 50 microg in the morning and salmeterol 50 mug in the evening (PACT combination), and montelukast 5 mg in the evening. Outcomes included asthma control days (primary outcome), exacerbations, humanistic measurements, and pulmonary function measurements.
                Fluticasone monotherapy and PACT combination were comparable in many patient-measured outcomes, including percent of asthma control days, but fluticasone monotherapy was superior for clinic-measured FEV(1)/forced vital capacity (P = .015), maximum bronchodilator response (P = .009), exhaled nitric oxide (P < .001), and PC(20) (P < .001). Fluticasone monotherapy was superior to montelukast for asthma control days (64.2% vs 52.5%; P = .004) and for all other control outcomes. Growth over 48 weeks was not statistically different (fluticasone, 5.3 cm; PACT combination, 5.3 cm; montelukast, 5.7 cm).
                Both fluticasone monotherapy and PACT combination achieved greater improvements in asthma control days than montelukast. However, fluticasone monotherapy was superior to PACT combination in achieving other dimensions of asthma control. Growth was similar in all groups.
                Therefore, of the regimens tested, the PACT study findings favor fluticasone monotherapy in treating children with mild-moderate persistent asthma with FEV(1) >or= 80% predicted, confirming current guideline recommendations. Outcome data are needed to base recommendations for controller asthma medication use in school-aged children.
                We sought to determine intraindividual and interindividual response profiles and predictors of response to an inhaled corticosteroid (ICS) and a leukotriene receptor antagonist (LTRA).
                An ICS, fluticasone propionate (100 mug twice daily), and an LTRA, montelukast (5-10 mg nightly, age dependent), were administered to children ages 6 to 17 years with mild-to-moderate persistent asthma using only as-needed bronchodilators in a multicenter, double-masked, 2-sequence, 16-week crossover trial. Clinical, pulmonary, and inflammatory responses to these controllers were evaluated.
                Improvements in most clinical asthma control measures occurred with both controllers. However, clinical outcomes (asthma control days [ACDs], the validated Asthma Control Questionnaire, and albuterol use), pulmonary responses (FEV(1)/forced vital capacity, peak expiratory flow variability, morning peak expiratory flow, and measures of impedance), and inflammatory biomarkers (exhaled nitric oxide [eNO]) improved significantly more with fluticasone than with montelukast treatment. eNO was both a predictor of ACDs (P = .011) and a response indicator (P = .003) in discriminating the difference in ACD response between fluticasone and montelukast.
                The more favorable clinical, pulmonary, and inflammatory responses to an ICS than to an LTRA provide pediatric-based group evidence to support ICSs as the preferred first-line therapy for mild-to-moderate persistent asthma in children. eNO, as a predictor of response, might help to identify individual children not receiving controller medication who achieve a greater improvement in ACDs with an ICS compared with an LTRA. For children who have uncontrolled asthma despite the use of low-dose inhaled corticosteroids (ICS), evidence to guide step-up therapy is lacking.
                We randomly assigned 182 children (6 to 17 years of age), who had uncontrolled asthma while receiving 100 microg of fluticasone twice daily, to receive each of three blinded step-up therapies in random order for 16 weeks: 250 microg of fluticasone twice daily (ICS step-up), 100 microg of fluticasone plus 50 microg of a long-acting beta-agonist twice daily (LABA step-up), or 100 microg of fluticasone twice daily plus 5 or 10 mg of a leukotriene-receptor antagonist daily (LTRA step-up). We used a triple-crossover design and a composite of three outcomes (exacerbations, asthma-control days, and the forced expiratory volume in 1 second) to determine whether the frequency of a differential response to the step-up regimens was more than 25%.
                A differential response occurred in 161 of 165 patients who were evaluated (P<0.001). The response to LABA step-up therapy was most likely to be the best response, as compared with responses to LTRA step-up (relative probability, 1.6; 95% confidence interval [CI], 1.1 to 2.3; P=0.004) and ICS step-up (relative probability, 1.7; 95% CI, 1.2 to 2.4; P=0.002). Higher scores on the Asthma Control Test before randomization (indicating better control at baseline) predicted a better response to LABA step-up (P=0.009). White race predicted a better response to LABA step-up, whereas black patients were least likely to have a best response to LTRA step-up (P=0.005).
                Nearly all the children had a differential response to each step-up therapy. LABA step-up was significantly more likely to provide the best response than either ICS or LTRA step-up. However, many children had a best response to ICS or LTRA step-up therapy, highlighting the need to regularly monitor and appropriately adjust each child's asthma therapy.

                2010 Massachusetts Medical Society Inhaled corticosteroids (ICS) may provide benefit in the therapy of acute asthma. The purpose of this study was to test the hypothesis that ICS are as effective as oral corticosteroids (OCS) in the management of acute childhood asthma.
                A randomized, masked, placebo-controlled study was conducted in children aged 6 to 16 years seeking emergent care for an acute exacerbation of asthma. Patients were randomized into one of two groups: group 1 (OCS), oral prednisone, 2 mg/kg (maximum of 60 mg/d) for 7 days, and placebo pressurized metered-dose inhaler with valved holding chamber, four inhalations bid; and group 2 (ICS), flunisolide, four inhalations (1 mg) bid for 7 days, and daily placebo tablets. Spirometry (FEV(1)) was performed at baseline, day 3, and day 7 of the study. A symptom diary and twice-daily peak expiratory flow were recorded.
                A total of 58 subjects receiving ICS (n = 27) or OCS (n = 28) were enrolled. Baseline asthma severity, race, gender, and age were balanced between the two groups. chi(2) showed no significant difference in symptom severity between the two groups at any time during the study. FEV(1) percentage of predicted was lower in the ICS group on day 3 (65% vs 78%, p = 0.03) and on day 7 (77% vs 95%, p = 0.002).
                ICS were found to be useful in the management of acute asthma in children; however, spirometry data suggested a more rapid resolution of asthma with OCS. Inhaled corticosteroids (ICSs) are widely used in combination with other classes of drugs for treatment of childhood asthma. The efficacy and the safety of montelukast added to low-dose ICS therapy were compared with those of sustained-release theophylline added to low-dose ICS therapy in asthmatic children in the present study.
                Following the 2-week run-in period, 6-to 14-year old patients receiving treatment with ICSs were randomized to treatment for 4 weeks with either montelukast 5 mg once daily or sustained release theophylline 5-8 mg/kg (dry syrup) or 100-200 mg (tablet) twice daily. Patients also received a fixed dose of ICS throughout the run-in and treatment periods. The primary efficacy endpoint was the change from baseline in peak expiratory flow (PEF) at Week 2.
                A significant increase in morning PEF was observed in the add-on montelukast group as compared with the add-on theophylline group at Week 2 (change from baseline of 22.8 L/minvs. 8.7 L/min; p = 0.041 for between-group difference) and at Week 4 (31.0 L/minvs. 9.8 L/min; p = 0.012). A significant increase in evening PEF was observed in the add-on montelukast group as compared with the add-on theophylline group at Week 4 (24.7 L/minvs. 8.7 L/min; p = 0.027). There were no significant differences between the treatment groups in incidences of clinical and laboratory adverse experiences.
                The results indicate that montelukast added to low-dose ICS is an effective and safe option for the treatment of asthma in children. Lung inflammation and injury is critical in cystic fibrosis. An ideal antiinflammatory agent has not been identified but inhaled corticosteroids are widely used despite lack of evidence.
                To test the safety of withdrawal of inhaled corticosteroids with the hypothesis this would not be associated with an earlier onset of acute chest exacerbations.
                Multicenter randomized double-blind placebo-controlled trial in 18 pediatric and adult UK centers. Eligibility criteria included age>6.0 yr, FEV1>or=40% predicted, and corticosteroid use>3 mo. During the 2-mo run-in period, all patients received fluticasone; they then took either fluticasone or placebo for 6 mo.
                Fluticasone group: n=84, median age 14.6 yr, mean (SD) FEV1 76% (18); placebo group: n=87, median age 15.8 yr, mean (SD) FEV1 76% (18). There was no difference in time to first exacerbation (primary outcome) with hazard ratio (95% confidence interval) of 1.07 (0.68 to 1.70) for fluticasone versus placebo. There was no effect of age, atopy, corticosteroid dose, FEV1, or Pseudomonas aeruginosa status. There was no change in lung function or differences in antibiotic or rescue bronchodilator use. Fewer patients in the fluticasone group withdrew from the study due to lung-related adverse events (9 vs. 15%); with a relative risk (95% confidence interval) of 0.59 (0.23-1.48) fluticasone versus placebo.
                In this study population (applicable to 40% of patients with cystic fibrosis in the UK), it appears safe to consider stopping inhaled corticosteroids. Potential advantages will be to reduce the drug burden on patients, reduce adverse effects, and make financial savings. A fixed combination of long-acting beta(2)-agonists (LABA) plus inhaled corticosteroids (ICS) has never been proven to reduce asthma exacerbations vs ICS alone in children. This 12-month, double-blind, randomized study in 341 children (age range, 4 to 11 years) with asthma uncontrolled on ICS investigated whether a novel regimen using budesonide/formoterol for maintenance and reliever therapy (Symbicort maintenance and relief therapy [SMART]) [Symbicort; AstraZeneca R&D, Lund, Sweden] could reduce exacerbations.
                Patients received SMART (budesonide/formoterol 80/4.5 microg qd maintenance plus additional inhalations for symptom relief), budesonide/formoterol 80/4.5 microg qd for maintenance (fixed combination), or higher-dose budesonide 320 microg qd (fixed-dose budesonide). Blinded as-needed medication (terbutaline 0.4 microg) was provided in both fixed-dose groups.
                SMART prolonged the time to first exacerbation vs fixed-dose budesonide (p = 0.02) and fixed-dose combination (p < 0.001). Rates of exacerbation requiring medical intervention were reduced by 70 to 79% with SMART vs fixed-dose budesonide and fixed-dose combination (0.08/patient vs 0.28/patient and 0.40/patient, respectively; both p < 0.001). Mild exacerbation days and awakenings were significantly lower with SMART; yearly growth improved by 1.0 cm vs fixed-dose budesonide (p < 0.01).
                The SMART regimen using budesonide/formoterol for both maintenance and as-needed symptom relief reduces the exacerbation rate compared with both fixed-dose combination and higher fixed-dose ICS alone in children with asthma. Inhaled corticosteroids are established first-line anti-inflammatory treatment for asthma. Clinical trials comparing inhaled corticosteroids must take into consideration that because of their excellent effect at low doses, they typically induce a near-maximal response in asthma patients.
                The aim of the present dose-response study was to estimate the minimal effective doses (MEDs) of budesonide and of fluticasone propionate via dry-powder inhaler in adults with mild to moderate asthma.
                This was a randomized, double-blind, double-dummy, parallel-group, multicenter, dose-reduction trial performed in adults to compare these 2 inhaled corticosteroids. After a 4- to 6-week run-in period with beclomethasone dipropionate 2000 pg/d, patients fulfilling defined criteria for asthma control were randomly allocated to treatment with budesonide or fluticasone, both administered BID at a total of 800 pg/d. At 5-week intervals, the dose was reduced to 400 and then 200 pg/d (200 and 100 pg BID) if asthma control was maintained according to further defined criteria. The MED was defined as the last dose level before deterioration of asthma control.
                Subjects were 197 asthmatic patients with a mean age of 40.6 years in the budesonide group and 41.5 years in the fluticasone group. In both groups, baseline mean forced expiratory volume in 1 second (FEV(1)) was 79.4% of the predicted normal volume and baseline mean FEV(1) reversibility was 22.3%. The median MED for both groups was 400 microg/d, with no detectable difference in dis-tributions. The budesonide-to-fluticasone ratio for the geometric mean MED was 123% (95% CI, 99-153 [not significant]). No statistically significant differences regarding lung function, symptom scores, or rescue medication usage were found between the treatment groups during the first treatment period. Adverse-event profiles were similar in both groups, and no unexpected adverse events were considered to be caused by the study drugs.
                This effect-controlled study did not detect a statistically significant difference between the MEDs for budesonide and fluticasone via dry-powder inhaler in adults with mild to moderate asthma. To compare the effect of inhaled budesonide given daily or as-needed on mild persistent childhood asthma. Patients, design and
                176 children aged 5-10 years with newly detected asthma were randomly assigned to three treatment groups: (1) continuous budesonide (400 microg twice daily for 1 month, 200 microg twice daily for months 2-6, 100 microg twice daily for months 7-18); (2) budesonide, identical treatment to group 1 during months 1-6, then budesonide for exacerbations as needed for months 7-18; and (3) disodium cromoglycate (DSCG) 10 mg three times daily for months 1-18. Exacerbations were treated with budesonide 400 microg twice daily for 2 weeks.
                Lung function, the number of exacerbations and growth.
                Compared with DSCG the initial regular budesonide treatment resulted in a significantly improved lung function, fewer exacerbations and a small but significant decline in growth velocity. After 18 months, however, the lung function improvements did not differ between the groups. During months 7-18, patients receiving continuous budesonide treatment had significantly fewer exacerbations (mean 0.97), compared with 1.69 in group 2 and 1.58 in group 3. The number of asthma-free days did not differ between regular and intermittent budesonide treatment. Growth velocity was normalised during continuous low-dose budesonide and budesonide therapy given as needed. The latter was associated with catch-up growth.
                Regular use of budesonide afforded better asthma control but had a more systemic effect than did use of budesonide as needed. The dose of ICS could be reduced as soon as asthma is controlled. Some children do not seem to need continuous ICS treatment. Inhaled corticosteroids are highly effective in the treatment of asthma at all ages and their use in younger children is increasing. As concerns exist about the long-term systemic side-effects of high dose inhaled corticosteroids, current guidelines continue to recommend sodium cromoglycate (SCG) as first line regular medication for children with frequent symptoms. Few published studies have compared the safety and efficacy of inhaled corticosteroids with SCG in children. This study compares SCG with the new inhaled corticosteroid, fluticasone propionate (FP), which has theoretical advantages over other currently available corticosteroids due to its negligible oral bioavailability. This was a randomized, open, multi-centre, parallel group comparison of 50 micrograms FP twice daily and 20 mg SCG four times daily over 8 weeks, preceded by a 2-week baseline period. Sixty-two general practices and two hospital centres enrolled 225 asthmatic children aged 4-12 years (110 received FP; 115 received SCG). Outcome measures improved in both groups, with a significant difference in favour of FP for the key variables of mean morning and evening % predicted PEFR and % of symptom-free days and nights. No significant difference was observed for FEV1, or relief medication use. Two children taking FP and 10 children taking SCG withdrew because of adverse events. This study showed that low dose FP was effective and superior to SCG in young children with mild-moderate asthma. Safety studies of longer duration are needed before changing the current recommendations for inhaled corticosteroid therapy. Although many asthmatic patients are treated with a combination of beta2 agonist and corticosteroid inhalers, the clinical effects of combining the drugs are unknown. Studies on the early asthmatic response to allergen suggest that beta2 agonists may reduce the benefit of inhaled corticosteroids. A study of the effects of combining the drugs on asthma control was undertaken.
                Sixty one subjects with mild to moderate asthma were randomised to a double blind crossover comparison of inhaled budesonide (200-400 microg twice daily), terbutaline (500-1000 microg four times daily), combined treatment, and placebo. Each treatment was given for six weeks following a four week washout period. Ipratropium was used for symptom relief. Treatments were ranked from worst (1) to best (4) based on need for oral steroid, mean morning peak flow, nocturnal awakening, ipratropium use, and asthma symptoms. Lung function and bronchial hyperresponsiveness were measured before and after each treatment.
                Evaluable data for all four treatments were obtained from 47 subjects. The mean rank of each treatment was: placebo = 2.05; terbutaline = 2.13; budesonide = 2.48; combined treatment = 3.34. Combined treatment was ranked significantly better than any other treatment (p<0.01). Mean (95% CI) morning and evening peak flows were 14 (5 to 23) and 24 (15 to 34) l/min higher, respectively, during combined treatment than during budesonide, and 27 (17 to 37) and 15 (7 to 23) l/min higher than during terbutaline. Asthma symptoms tended to be least frequent during combined treatment but were not significantly different from budesonide alone. There was no significant difference between combined treatment and budesonide alone for lung function and bronchial hyperresponsiveness.
                In this group of mild to moderate asthmatic subjects the combination of beta2 agonist and corticosteroid gave better asthma control than either treatment alone. There was no evidence that regular beta2 agonist treatment impaired the beneficial effect of inhaled corticosteroid. To investigate the efficacy of an increased dose of inhaled steroid used within the context of an asthma self management plan for treating exacerbations of asthma.
                Randomised, double blind, placebo controlled, crossover trial.
                Twenty eight children aged 6-14 years with asthma of mild to moderate severity were studied for six months. Eighteen pairs of exacerbations were available for analysis, during which subjects took an increased dose of inhaled steroids or continued on the same dose.
                There was no significant difference between increasing inhaled steroids or placebo on morning or evening peak expiratory flow rates (PEFRs), diurnal peak flow variability, or symptom scores in the two weeks following an asthma exacerbation. Difference (95% confidence intervals) in baseline PEFR on days 1-3 were 3.4% (-3.5% to 10.4%) and -0.9% (-4.7% to 2.9%) for inhaled steroid and placebo, respectively. Spirometric function and the parents' opinion of the effectiveness of asthma medications at each exacerbation were also not significantly different between inhaled steroid or placebo.
                This study suggests that increasing the dose of inhaled steroids at the onset of an exacerbation of asthma is ineffective and should not be included in asthma self management plans. In a double blind, controlled trial, the effect of high dose beclomethasone dipropionate (750 micrograms three times daily for five days) administered by metered dose inhaler and valved spacer, was compared with placebo, during 70 paired episodes of acute asthma in 24 preschool children. Treatment commenced at home at the first sign of an attack. Parents' blind preference for active treatment was significant. Data from 17 pairs of treatment, however, were affected by interventions such as hospital admission or oral corticosteroid treatment. These events occurred similarly in active and control periods. An intrasubject comparison was made of diary scores from the 18 pairs of episodes in which no intervention occurred in either the active or placebo treatment. Both daytime and night symptoms over the first week of the attack were significantly reduced by active treatment. Intermittent high dose inhaled beclomethasone dipropionate is beneficial in modifying the severity of acute episodic asthma in preschool children able to use a spacer device. For children older than 5 years with asthma who remain symptomatic despite inhaled corticosteroid (ICS) therapy, the preferred treatment is to add an inhaled long-acting beta2-agonist vs increasing the ICS dose.
                To compare the safety of twice-daily treatment with inhaled fluticasone propionate plus the inhaled long-acting beta2-agonist salmeterol with that of fluticasone propionate used alone in children aged 4 to 11 years with persistent asthma.
                A randomized, multicenter, double-blind, active-controlled, parallel-group study in 203 children with persistent asthma who were symptomatic during ICS therapy. Patients received fluticasone propionate-salmeterol (100/50 microg) or fluticasone propionate (100 microg) alone twice daily for 12 weeks.
                The safety profile of fluticasone propionate-salmeterol was similar to that of fluticasone propionate alone. The overall incidence of adverse events was 59% for fluticasone propionate-salmeterol and 57% for fluticasone propionate. Both treatments were well tolerated. Two patients receiving fluticasone propionate-salmeterol and 5 receiving fluticasone propionate withdrew from the study because of worsening asthma. Changes in heart rate, blood pressure, and laboratory variables were infrequent and were similar between treatments. No patients had clinically significant abnormal electrocardiographic findings during treatment. Geometric mean 24-hour urinary cortisol excretion at baseline and after 12 weeks of treatment was comparable within and between groups; no patient in either group had abnormally low 24-hour urinary cortisol excretion after 12 weeks of treatment. The incidence of withdrawals due to asthma exacerbations was 2% in the fluticasone propionate-salmeterol group and 5% in the fluticasone propionate group.
                In pediatric patients with persistent asthma, fluticasone propionate-salmeterol twice daily was well tolerated, with a safety profile similar to that of fluticasone propionate used alone. Currently available anti-inflammatory treatment for young children with asthma includes inhaled corticosteroids (ICS) and the leukotriene receptor antagonist (LTRA) montelukast.
                To evaluate potential biomarkers of predicting short-term (6-week) response to ICS and LTRAs in children with asthma.
                A total of 102 children aged 4 to 7 years with episodic asthma were enrolled in an open labelled single-centre study. Biomarkers and asthma characteristics were evaluated as predictors of treatment. Of 102 patients 45 became symptomatic during observation and were randomised to treatment either to montelukast or fluticasone for 6 weeks.
                Forced Expiratory Volume in one second (FEV1) increased with both treatments: FEV1 at randomisation was 90.2% and after therapy 106.8% with fluticasone vs. 90.8% and 103.7% for montelukast, respectively, showing that montelukast and fluticasone were equally effective in this age group (p = 0.44). Strong correlations to a favourable treatment response were pre-bronchodilatory FEV1 (p < 0.001) and airway reversibility (p = 0.04) at time of randomisation. None of the other biomarkers (methacholine testing, exhaled nitric oxide [eNO], presence of allergy, total Immunoglobulin E [IgE], cumulative specific IgE, eosinophils and parental smoking) were predictive.
                Despite the small sample size and the open-label design, the study suggests that the use of pre-bronchodilatory FEV1 and airway reversibility appears to be a good indicator of short-term anti-inflammatory therapy in young children with asthma. To investigate the therapeutic efficacy of inhaled fluticasone propionate, started on day 1 of age, on ventilated preterm infants with respiratory distress syndrome.
                Starting within 24 hours of age, ventilated preterm infants (gestation < 32 weeks, birthweight < 1.5 kg) with respiratory distress syndrome were given a 14 day course (two puffs, 12 hourly) of either fluticasone propionate (250 microg/puff) (group 1, n=27) or placebo (group 2, n=26) with a metered dose inhaler-spacer device. Response to treatment was assessed by the rate of successful extubation by days 7 and 14 of age, changes in respiratory system mechanics, death, occurrence of chronic lung disease, and other neonatal complications.
                More infants in the treatment group were successfully extubated by 14 days of age than those in the placebo group (17/27 vs 8/26; p = 0.038). The treated infants also showed a more significant improvement in respiratory system compliance during the first 14 days of life. The two groups, however, did not differ significantly in their need for systemic steroids after day 14 of age, death, or the occurrence of chronic lung disease. The treatment was not associated with any increase in neonatal complications, including those attributable to steroid induced side effects.
                These results provide preliminary evidence that early treatment with inhaled corticosteroids may be beneficial to ventilated preterm infants with respiratory distress. Further study of its use in a large scale randomised trial is warranted. Controlling lung inflammation may be the key to improving morbidity and mortality in cystic fibrosis.

                Twenty three children from a regional cystic fibrosis centre were enrolled into the study, with mean age 10.3 years (range 7 to 17 years) and mean baseline forced expiratory volume in one second (FEV1) of 64% (range 21% to 102%) predicted for sex and height. One patient was excluded for non-compliance to the study protocol.
                No significant benefit was shown for the use of fluticasone propionate in any of the outcomes. For sputum interleukin-8 there was an estimated true treatment median difference of 142 pg/ml (95% confidence interval (CI) 8 to 2866 pg/ml) in favour of placebo; while for maximal expiratory flow at 25% (MEF25%) remaining forced vital capacity predicted for sex and height there was a 15 percentage points (pp) (95% CI 4 to 26 pp) mean treatment difference in favour of placebo. Sputum interleukin-10 was undetected in any samples and unaffected by fluticasone propionate. Neither atopic status, baseline FEV1, nor concomitant DNase therapy had any effect on response to treatment.
                Lack of benefit from fluticasone propionate was most likely due to failure of the drug to penetrate the viscid mucus lining the airways. It is suggested a large multicentre trial with higher doses given for a longer time by a different delivery system is required to assess efficacy. This long-term prospective study was conducted in African Americans with persistent asthma to examine the safety and effectiveness of the combination of the inhaled corticosteroid, fluticasone propionate (FP), and the long-acting beta-agonist, salmeterol, compared with FP alone.
                This was a randomized, double-blind, parallel group, multi-center trial in adolescent and adult subjects >/=12 years of age symptomatic on a low dose of an inhaled corticosteroid (ICS). The study consisted of a 2-week screening period on low dose ICS; a 4-week open-label FP 250 mcg twice daily (BID) run-in; a 52-week double-blind period (FP/salmeterol [FSC] 100/50 mcg [n=239] or FP 100 mcg [n=236] BID), and a 4-week FP 250 mcg BID run-out period. Annualized exacerbation rate was the primary outcome for comparing the two treatments. Other measures of asthma control included peak expiratory flow, asthma symptoms, and albuterol use. Safety was assessed through adverse events.
                Exacerbation rates were not significantly different in those treated with FSC 100/50 mcg (0.449 per year) compared with FP 100 mcg (0.529 per year, p=0.169). When the per-protocol analysis was applied, the rates were 0.465 and 0.769 per year for FSC 100/50 mcg and FP 100 mcg, respectively. Treatment with FSC 100/50 mcg provided statistically greater improvements in lung function measures and nighttime awakenings (p</=0.050) and demonstrated numerically lower daily symptoms (p=0.216) and albuterol use (p=0.122). Two subjects treated with FSC 100/50 mcg were hospitalized for an asthma exacerbation compared to three treated with FP 100 mcg. The overall incidence of adverse effects during double-blind treatment was similar between the FSC 100/50 mcg and FP 100 mcg treatment groups (61% and 68%, respectively). Frequent study visits were required of subjects during this long-term study, and it remains unknown whether this intervention may affect generalizability.
                In this large, prospective study among African Americans with asthma, the addition of salmeterol to FP resulted in a similar low rate of exacerbations and improved other markers of asthma control. Both FSC 100/50 mcg and FP 100 mcg were well-tolerated, and the overall safety-profiles were similar over 1 year of treatment. Inhaled corticosteroids are increasingly being used to treat mild-to-moderate asthma in children. However, data regarding therapy with this class of compounds, especially in children under age 6 years, is limited. Fluticasone propionate is a third generation inhaled corticosteroid with an optimal therapeutic index. Few large prospective clinical trials have been conducted to evaluate the efficacy and safety of fluticasone propionate powder in children.
                We sought to determine the efficacy and safety of fluticasone propionate powder administered by means of the Diskus and Diskhaler multidose powder inhalers in pediatric patients with persistent asthma.
                Fluticasone propionate powder (50 microg or 100 microg twice daily) or placebo was administered by means of the Diskus or Diskhaler inhalers to 437 children (4 to 11 years old) with persistent asthma for 12 weeks in a randomized, double-blind, parallel-group, multi-center trial. Patients were stratified according to whether they were receiving prior treatment with inhaled corticosteroids or cromolyn or beta2-agonists alone.
                Fluticasone propionate powder administered by means of Diskus or Diskhaler significantly improved FEV1 (mean increase from baseline of 0.22 to 0.24 L; p < or = 0.023), clinic morning peak expiratory flow (mean increase from baseline of 48 to 55 L/min; p < or = 0.006), patient-measured morning (p < or = 0.001) and evening (p < or = 0.003) peak expiratory flow, and asthma symptom scores (in all but the 50 microg Diskus group; p < or = 0.036), as well as reduced albuterol use (p < or = 0.002) and nighttime awakenings (p < or = 0.019) at endpoint. Efficacy parameters were not significantly different between the two doses with either device. More placebo-treated patients discontinued the study because of lack of efficacy than patients in any fluticasone propionate group (p < 0.001). Fluticasone propionate did not suppress morning plasma cortisol concentrations and did not affect 24-hour urinary free-cortisol excretion. Adverse events were primarily pharmacologic effects of inhaled corticosteroids, and those related to the study drug occurred with low frequency. Patient satisfaction with both the Diskus and Diskhaler devices was high, with a majority of patients (> 80%) rating them favorably.
                This study demonstrated that fluticasone propionate powder, at the conventional recommended doses of up to 200 microg/day administered by means of Diskus or Diskhaler, was well tolerated and improved lung function in children even as young as 4 and 5 years old regardless of whether they were previously treated with inhaled corticosteroids or cromolyn or beta2-agonists alone. To compare the efficacy and adverse effects of inhaled fluticasone propionate (FP), 400 microgram/d, with those of budesonide (BUD), 800 microgram/d, in children with moderate to severe asthma.
                Three hundred thirty-three children, ages 4 to 12 years, receiving inhaled corticosteroids were enrolled in a double-blind, double-dummy, randomized, parallel-group study. After a 2-week run-in phase, 166 children received FP and 167 received BUD for 20 weeks. The primary outcome variable was mean morning peak expiratory flow; the 2 treatments were to be regarded as equivalent if the 90% CI for the treatment difference was within +/- 15 L/min. Pulmonary function, height, and diary cards were assessed at each visit; and morning serum cortisol levels were determined before and after treatment.
                Baseline peak expiratory flow was similar, FP 236 +/- 72 (SD) L/min and BUD 229 +/- 74, increasing after treatment to 277 +/- 41 and 257 +/- 28, a difference between treatments of 12 L/min (90% CI 6-19 L/min; P =.002). Symptom control and use of rescue medication were the same. Cortisol levels after treatment were 199 nmol/L (FP) and 183 nmol/L (BUD) (treatment ratio = 1.09; 90% CI 0.98-1.21; P =.172). Linear growth was less in those receiving BUD (mean difference, 6.2 mm; 95% CI 2.9-9.6; P =.0003).
                FP at half the dose was superior to BUD in improving peak expiratory flow and comparable in controlling symptoms. Growth was reduced with BUD compared with FP, but there was no difference in serum cortisol suppression or hepatic or renal function. Responses to inhaled corticosteroids (ICSs) and leukotriene receptor antagonists (LTRAs) vary among asthmatic patients.
                We sought to determine whether responses to ICSs and LTRAs are concordant for individuals or whether asthmatic patients who do not respond to one medication respond to the other.
                Children 6 to 17 years of age with mild-to-moderate persistent asthma were randomized to one of 2 crossover sequences, including 8 weeks of an ICS, fluticasone propionate (100 microg twice daily), and 8 weeks of an LTRA, montelukast (5-10 mg nightly depending on age), in a multicenter, double-masked, 18-week trial. Response was assessed on the basis of improvement in FEV 1 and assessed for relationships to baseline asthma phenotype-associated biomarkers.
                Defining response as improvement in FEV 1 of 7.5% or greater, 17% of 126 participants responded to both medications, 23% responded to fluticasone alone, 5% responded to montelukast alone, and 55% responded to neither medication. Compared with those who responded to neither medication, favorable response to fluticasone alone was associated with higher levels of exhaled nitric oxide, total eosinophil counts, levels of serum IgE, and levels of serum eosinophil cationic protein and lower levels of methacholine PC(20) and pulmonary function; favorable response to montelukast alone was associated with younger age and shorter disease duration. Greater differential response to fluticasone over montelukast was associated with higher bronchodilator use, bronchodilator response, exhaled nitric oxide levels, and eosinophil cationic protein levels and lower methacholine PC(20) and pulmonary function values.
                Response to fluticasone and montelukast vary considerably. Children with low pulmonary function or high levels of markers associated with allergic inflammation should receive ICS therapy. Other children could receive either ICSs or LTRAs. In order to assess the efficacy of a combination of systemic and nebulized corticosteroids in reducing the incidence and severity of chronic lung disease (CLD) in very low birthweight (VLBW) infants, 60 ventilator-dependent infants < or = 1500 g were randomly assigned to receive either steroids or placebo as of 7 d. The steroid group (n = 30, GA = 25.8 +/- 1.6 weeks, BW = 731 +/- 147 g) received systemic dexamethasone for 3 d, followed by nebulized budesonide for 18 d. Control infants (n = 30, GA = 25.9 +/- 1.8 weeks, BW = 796 +/- 199 g) received systemic and inhaled saline. Steroid-treated infants required less ventilatory support between 9 and 17 d (p < 0.01), and had greater lung compliance at 10 d (p = 0.01), but not subsequently. CLD incidence at 36 weeks was 45.5% vs 56.0% in controls, and fewer steroid-treated infants required dexamethasone rescue (23.3% vs 56.7%, p = 0.017). Survival to discharge was similar (73.3% vs 83.3%), as were the durations of mechanical ventilation, supplemental oxygen use, and hospitalization. Tracheal effluent elastase/albumin ratios and serum cortisol values did not differ between groups, and no adverse effects were noted. We conclude that early dexamethasone administration was associated with improved pulmonary function, which was not sustained with nebulized budesonide. However, the steroid regimen studied reduced the need for dexamethasone rescue in infants with CLD. Ciclesonide (CIC) is an inhaled corticosteroid (ICS) with high anti-inflammatory activity and low incidence of local and systemic adverse effects. The objective of this study was to compare the efficacy and safety of CIC with fluticasone propionate (FP) in children and adolescents with persistent asthma. This was a 12-week, randomized, double blind, parallel-group study. After a 2-to 4-week baseline period, a total of 556 children (ages 6-15 years) with asthma (forced expiratory volume in 1 sec [FEV(1)], 50% to 90% predicted) were treated twice daily with CIC 80 microg (ex-actuator, equivalent to 100 microg ex-valve) or FP 88 microg (ex-actuator, equivalent to 100 microg ex-valve) administered via a hydrofluoroalkane-propelled metered-dose inhaler. A statistically significant increase from baseline was observed in FEV(1) for both CIC (285 +/- 16 ml) and FP (285 +/- 15 ml) (P < 0.0001 for both) and in morning and evening peak expiratory flow (P < 0.0001 for both). Significant improvements were seen in asthma symptoms, use of rescue medication, and asthma symptom-free days in both treatment groups, without any differences between the treatment groups in changes from baseline. Two FP-treated patients experienced oral candidiasis and one patient experienced voice alteration. Creatinine-adjusted 24-hr urine cortisol levels increased from baseline levels by 10% in the CIC group (P < 0.05) and by 6% in the FP group (not significant). The efficacy and safety of CIC 160 microg/day were comparable to those of FP 176 microg/day in children with asthma.
                (c) 2006 Wiley-Liss, Inc. In the treatment of asthma, inhaled steroids are more effective than cromolyn, whereas the latter offers extreme safety. The aim of the present pilot study was to evaluate, contemporarily, efficacy and safety aspects of different asthma treatment modalities. In 75 school-age children (mean age 9.5 years; range 5.5-14.7 years), treatment of asthma was started with budesonide (BUD, n = 30), fluticasone propionate (FP, n = 30) or cromones (CROM, n = 15). BUD was used at a dose of 800 microg/day during the first 2 months and at 400 microg/day thereafter. The respective FP doses were 500 and 200 microg/day. Efficacy of the treatment was assessed by measuring forced expiratory volume in 1 second (FEV1) and by evaluating the use of bronchodilators. Side-effects of the treatment were evaluated by following growth of the children and by performing low-dose adrenocorticotropin (ACTH) testing. At 4 months FEV1 had improved by a mean of 8.2% in the BUD group and by 5.4% in the FP group (p< 0.01 vs. baseline in both groups; NS between BUD and FP groups). The use of bronchodilators had decreased from five doses/week to one dose/week in the BUD group (p< 0.05), and from three doses/week to one dose/week in the FP group (p< 0.01) (NS between the groups). In the CROM group, the FEV1 value and the use of bronchodilators did not change. The treatment was unsuccessful on the basis of FEV1 decrease and increased bronchodilator use in, respectively, 30 and 15% of the BUD-, 20 and 7% of the FP-, and 50 and 47% of the CROM-treated children. Therefore, to prevent one treatment failure in the CROM group, between three and five children would need to move to treatment with steroids. The treatment had measurable systemic effects on the basis of height standard deviation (SD) score decrease and minor adrenocortical suppression in, respectively, 60 and 30% of the BUD-, 27 and 17% of the FP-, and 20 and 0% of the CROM-treated children. Therefore, to avoid systemic effects in one steroid-treated child, three BUD- and six to 14 FP-treated children would need to move to treatment with CROM. In conclusion, in school-age children asthma should be treated first with inhaled steroids. It is probable that the best combination of efficacy and safety can be achieved by using low steroid doses. The aim of this study was to compare the efficacy and safety of salmeterol/fluticasone propionate combination product (SFC) with fluticasone propionate (FP) plus oral montelukast (M) over 12 weeks in symptomatic asthma patients. The study was a multinational, randomised, double-blind, double-dummy, parallel-group design in patients aged > or = 15 years. After a 4-week run-in during which all patients received FP 100 microg twice daily, patients were randomised to inhaled SFC (50/100 microg) twice daily or inhaled FP 100 microg twice daily and oral M 10 mg once daily. Patients kept daily records of their peak expiratory flow (PEF) symptom scores and use of rescue medication. Over the 12-week treatment period, the adjusted increase in mean morning PEF was significantly greater in the SFC group (36 l/min) than the FP/M group (19 l/min; P < 0.001). The improvement in FEV1 was also significantly greater in the SFC group (mean treatment difference 0.11 l; P < 0.001). SFC provided significantly better control of daytime and night-time symptoms and there were fewer exacerbations. Patients in the SFC group were also significantly more likely to have a rescue-free day. Both treatments were equally well tolerated. Combination therapy with FP plus salmeterol (SFC) produced significantly greater improvements in lung function and asthma control than the addition of montelukastto FP. Asthma is a disease of chronic inflammation and bronchoconstriction. Inhaled corticosteroids (ICSs) provide important anti-inflammatory treatment but may not provide optimal control of asthma when taken alone. Two therapeutic alternatives for enhanced asthma control are to substitute the combination of fluticasone propionate (FP) and salmeterol (FP/Salm Combo) through the Diskus inhaler or to add montelukast to existing ICS therapy.
                We compared the efficacy and safety of FP/Salm Combo through the Diskus inhaler versus montelukast added to FP (FP + montelukast) in patients whose symptoms were suboptimally controlled with ICS therapy.
                We performed a multicenter, double-blind, double-dummy, parallel-group, 12-week study in 447 patients with asthma who were symptomatic at baseline while receiving low-dose FP. Patients were treated for 12 weeks with one of the following: (1) combination of FP 100 microg plus salmeterol 50 microg twice daily through the Diskus inhaler, or (2) FP 100 microg twice daily through the Diskus inhaler plus oral montelukast 10 mg once daily.
                FP/Salm Combo treatment provided better overall asthma control than FP + montelukast with significantly greater improvements in morning peak expiratory flow (+24.9 L/min vs +13.0 L/min, P <.001), evening peak expiratory flow (+18.9 L/min vs +9.6 L/min, P <.001), and forced expiratory volume in 1 second (+0.34 L vs +0.20 L, P <.001), as well as a change in the percentage of days with no albuterol use (+26.3% vs +19.1%, P =.032) and the shortness of breath symptom score (-0.56 vs -0.40, P =.017). The groups had comparable improvements in chest tightness, wheeze, and overall symptom scores. Asthma exacerbation rates were significantly lower (P =.031) in the FP/Salm Combo group (4 patients, 2%) than in the FP + montelukast group (13 patients, 6%). Adverse event profiles were comparable.
                Symptomatic patients on low-dose ICS therapy had significantly greater improvement in asthma control when switched to the FP/Salm Combo than when montelukast was added to ICS therapy.
In adolescents and adults with sub-optimal control on low dose ICS monotherapy, the combination of LABA and ICS is modestly more effective in reducing the risk of exacerbations requiring oral corticosteroids than a higher dose of ICS. Combination therapy also led to modestly greater improvement in lung function, symptoms and use of rescue ß2 agonists and to fewer withdrawals due to poor asthma control than with a higher dose of inhaled corticosteroids. Apart from an increased rate of tremor and less oral candidiasis with combination therapy, the two options appear relatively safe in adults although adverse effects associated with long-term ICS treatment were seldom monitored. In children, combination therapy did not lead to a significant reduction, but rather a trend towards an increased risk, of oral steroid-treated exacerbations and hospital admissions. These trends raised concern about the safety of combination therapy in view of modest improvement in children under the age of 12 years.
