The efficacy and safety of fluticasone/salmeterol compared to fluticasone in children younger than four years of age.

ABSTRACT: BACKGROUND:Fluticasone propionate 50 ?g/salmeterol xinafoate 25 ?g (FP/SAL) is widely used in adults and children with asthma, but there is sparse information on its use in very young children. METHODS:This was a randomized, double-blind, multicentre, controlled trial conducted in children aged 8 months to 4 years. During a 2-week run-in period, they all received FP twice daily. At randomization, they commenced FP/SAL or FP twice daily for 8 weeks. All were then given FP/SAL only, in a 16-week open-label study continuation. Medications were inhaled through an AeroChamber Plus with attached face mask. The primary end-point was mean change in total asthma symptom scores from baseline to the last 7 days of the double-blind period. Analyses were undertaken in all children randomized to treatment and who received at least one dose of study medication. RESULTS:Three hundred children were randomized 1:1 to receive FP/SAL or FP. Mean change from baseline in total asthma symptom scores was -3.97 for FP/SAL and -3.01 with FP. The between-group difference was not statistically significant (P = 0.21; 95% confidence interval: -2.47, 0.54). No new safety signals were seen with FP/SAL. CONCLUSION:This is the first randomized, double-blind study of this size to evaluate FP/SAL in very young children with asthma. FP/SAL did not show superior efficacy to FP; no clear add-on effect of SAL was demonstrated. No clinically significant differences in safety were noted with FP/SAL usage.

Project description:BackgroundDespite the recommendation of inhaled corticosteroids (ICSs) plus long-acting beta 2-agonist (LABA) and leukotriene receptor antagonist (LTRA) or ICS/LTRA as stepwise approaches in asthmatic children, there is a lack of published systematic review comparing the efficacy and safety of the two therapies in children and adolescents aged 4 to 18 years. This study aimed to compare the safety and efficacy of salmeterol/fluticasone (SFC) vs. montelukast (MON), or combination of montelukast and fluticasone (MFC) in children and adolescents aged 4 to 18 years with bronchial asthma.MethodsA systematic search was conducted in MEDLINE, EMBASE, the Cochrane Library, China BioMedical Literature Database, Chinese National Knowledge Infrastructure, VIP Database for Chinese Technical Periodical, and Wanfang for randomized controlled trials (RCTs) published from inception to May 24, 2021. Interventions are as follows: SFC vs. MON, or combination of MFC, with no limitation of dosage or duration. Primary and secondary outcome measures were as follows: the primary outcome of interest was the risk of asthma exacerbation. Secondary outcomes included risk of hospitalization, pulmonary function, asthma control level, quality of life, and adverse events (AEs). A random-effects (I2 ≥ 50%) or fixed-effects model (I2 < 50%) was used to calculate pooled effect estimates, comparing the outcomes between the intervention and control groups where feasible.ResultsOf the 1006 articles identified, 21 studies met the inclusion criteria with 2643 individuals; two were at low risk of bias. As no primary outcomes were similar after an identical treatment duration in the included studies, meta-analysis could not be performed. However, more studies favored SFC, instead of MON, owing to a lower risk of asthma exacerbation in the SFC group. As for secondary outcome, SFC showed a significant improvement of peak expiratory flow (PEF)%pred after 4 weeks compared with MFC (mean difference [MD]: 5.45; 95% confidence interval [CI]: 1.57-9.34; I2 = 95%; P = 0.006). As for asthma control level, SFC also showed a higher full-controlled level (risk ratio [RR]: 1.51; 95% CI: 1.24-1.85; I2 = 0; P < 0.001) and higher childhood asthma control test score after 4 weeks of treatment (MD: 2.30; 95% CI: 1.39-3.21; I2 = 72%; P < 0.001) compared with MFC.ConclusionsSFC may be more effective than MFC for the treatment of asthma in children and adolescents, especially in improving asthma control level. However, there is insufficient evidence to make firm conclusive statements on the use of SFC or MON in children and adolescents aged 4 to 18 years with asthma. Further research is needed, particularly a combination of good-quality long-term prospective studies and well-designed RCTs.Prospero registration numberCRD42019133156.

Project description:BackgroundNeonates and young children require efficacious magnetic resonance imaging (MRI) examinations but are potentially more susceptible to the short- and long-term adverse effects of gadolinium-based contrast agents due to the immaturity of their body functions.ObjectiveTo evaluate the acute safety and diagnostic efficacy of gadoteridol (ProHance) for contrast-enhanced MRI of the central nervous system (CNS) in children ≤2 years of age.Materials and methodsOne hundred twenty-five children ≤2 years old (including 57 children <6 months old) who underwent contrast-enhanced MRI of the CNS with gadoteridol at 0.1 mmol/kg body weight were retrospectively enrolled at five imaging centers. Safety data were assessed for acute/subacute adverse events in the 48 h following gadoteridol administration and, when available, vital signs, electrocardiogram (ECG) and clinical laboratory values obtained from blood samples taken from 48 h before until 48 h following the MRI exam. The efficacy of gadoteridol-enhanced MRI compared to unenhanced MRI for disease diagnosis was evaluated prospectively by three blinded, unaffiliated readers.ResultsThirteen changes of laboratory values (11 mild, 1 moderate, 1 unspecified) were reported as adverse events in 7 (5.6%) patients. A relationship to gadoteridol was deemed possible though doubtful for two of these adverse events in two patients (1.6%). There were no clinical adverse events, no serious adverse events and no clinically meaningful changes in vital signs or ECG recordings. Accurate differentiation of tumor from non-neoplastic disease, and exact matching of specific MRI-determined diagnoses with on-site final diagnoses, was achieved in significantly more patients by each reader following the evaluation of combined pre- and post-contrast images compared to pre-contrast images alone (84.6-88.0% vs. 70.9-76.9%; P≤0.006 and 67.5-79.5% vs. 47.0-66.7%; P≤0.011, respectively).ConclusionGadoteridol at 0.1 mmol/kg body weight is safe, well tolerated and effective for contrast-enhanced MRI of the CNS in children ≤2 years of age.

Project description:BackgroundImproving patients' health-related quality of life (HRQoL) is recognized as a fundamental part of asthma management. The aims of this study were to evaluate the long-term efficacy (including symptom-free days and exacerbations) and impact on HRQoL of a stable-dose regimen of salmeterol/fluticasone propionate (SAL/FP) and an adjustable maintenance dosing (AMD) regimen of formoterol/budesonide (FOR/BUD) where treatment is adjusted based on symptoms [SAM40056].MethodsA total of 688 outpatients with asthma receiving regular low-dose inhaled corticosteroids (ICS) plus a long-acting beta2-agonist, or medium dose ICS alone participated in this randomized, double-blind, double-dummy, parallel-group, 1-year trial, which was conducted in 91 centers in 15 countries. Patients were randomized to receive 1 inhalation of SAL/FP 50/250 mug BID or 2 inhalations of FOR/BUD 6/200 mug BID during Weeks 1-4. For Weeks 5-52, patients meeting strict continuation criteria for stable asthma at Week 4 received AMD with FOR/BUD or stable-dose SAL/FP.ResultsThe percentage of symptom-free days was significantly greater (58.8% vs 52.1%; p = 0.034) and the annual exacerbation rate was significantly lower (47%; p = 0.008) with stable-dose SAL/FP compared with FOR/BUD AMD. A total of 568 patients completed the Asthma Quality of Life Questionnaire (AQLQ) at least once during the study. The mean change from baseline in AQLQ overall score was numerically greater with SAL/FP than FOR/BUD at week 28 and week 52, but did not reach statistical significance (p = 0.121 at Week 52). However, in a post hoc logistic regression analyses for any AQLQ improvement, significant benefits with SAL/FP were seen at both time points (p = 0.038 and p = 0.009, respectively). The minimally important difference of >/= 0.5-point improvement in AQLQ overall score was achieved by a significantly greater number of patients receiving SAL/FP at Week 28 (68% vs 60%; p = 0.049); a trend for this difference remained at Week 52 (71% vs 65%) (p = 0.205).ConclusionIn this population of patients with persistent asthma, stable-dose SAL/FP resulted in significantly greater increases in symptom-free days, a reduction in exacerbation rates, and provided greater HRQoL benefits compared with FOR/BUD AMD.Trial registrationClinical Trials registration number NCT00479739.
