Efficacy of budesonide/formoterol maintenance and reliever therapy compared with higher-dose budesonide as step-up from low-dose inhaled corticosteroid treatment

Electronic health record data analysis on the impact of rescue-triggered inhaled corticosteroids on controller therapy in Black and Latinx individuals from a pragmatic, open-label, patient-level randomised trial

OBJECTIVE

The Person Empowered Asthma Relief (PREPARE) study found that as-needed inhaled corticosteroid (ICS) supplementation combined with participants' usual controller and rescue therapy reduced asthma exacerbations for Black and Hispanic/Latinx individuals. We aimed to determine whether treatment assignment to the intervention group (Patient Activated Reliever-Triggered ICS (PARTICS)) versus the control group (usual care) influenced controller therapy based on clinicians' written prescriptions.

DESIGN

Secondary data analysis of electronic health record data of a pragmatic, open-label, patient-level randomised trial.

SETTING

Practices treating asthma.

PARTICIPANTS

PREPARE study participants- Black and Hispanic/Latinx individuals with asthma.

INTERVENTIONS

Effects of adding ICS to rescue therapy among black and Hispanic adults with moderate-to-severe asthma.

OUTCOME MEASURES

For PARTICS therapy impact on patients, each month is the 28-month period (12 months prior to enrolment, the month of enrolment and 15 months after enrolment), a patient was assigned to a controller step based on a six-step classification scheme. A linear mixed effect spline model was completed for before and after enrolment data to determine controller changes over a 28-month period between the two study arms.

RESULTS

This analysis included 713 participants. Of these, 49.1% were usual care patients and 50.9% were PARTICS patients. Throughout the study, the majority of patients changed asthma controller medications in both arms. By the end of the study, the usual care patients were at a significantly higher asthma controller medication step (0.20 step higher) than the PARTICS patients.

CONCLUSIONS

Clinicians' prescribing patterns showed significant changes over time. Compared with usual care patients, PARTICS patients were on lower doses of asthma controller medications by the end of the study.

Budesonide/formoterol maintenance and reliever therapy in childhood asthma: Real-world effectiveness and economic assessment

INTRODUCTION

The study aims to compare the real-world effectiveness and economy of the budesonide/formoterol reliever and maintenance therapy (SMART) with fixed-dose inhaled corticosteroids (ICS)/long-acting b-agonist (LABA) or ICS alone plus as-needed, short-acting β2 agonists (SABA) in pediatric patients.

METHODS

The outpatient data warehouse of a hospital in China was used. A total of 103 patients under 18 years old in the SMART group and 63 patients in the control group were included from January 1, 2020 to December 31, 2021. The effectiveness was assessed using asthma attacks and lung function at baseline, 6 months and 12 months follow-up. Cost-effectiveness analysis was performed with a three-state Markov model from the healthcare system perspective. One-way sensitivity analyses and probabilistic sensitivity analyses were performed to check the robustness of the results.

RESULTS

The SMART regimen was more effective than other strategies in reducing the risk of mild and severe attacks in the real-life management of childhood asthma. Patients in both groups showed significant improvement in lung function at 6 and 12 months in contrast to baseline. Compared with other strategies, the forced expiratory volume in 1 s (FEV1 ) level in the SMART group was markedly improved at 6 months. The total cost of outpatient service using the SMART regimen was lower than that of other strategies, while the drug costs were similar in different groups. Incremental cost-effectiveness analysis results showed that using the SMART regimen reduced the total cost by approximately CNY 10,516.11 per year with a 0.12 quality-adjusted life year (QALYs) increase. Sensitive analyses supported that the SMART regimen was the dominant choice at the willingness-to-pay threshold of CNY 85,698, per capita GDP in China.

CONCLUSIONS

Collectively, our findings indicate that the real-world effectiveness and economy of the SMART regimen are superior to the traditional strategies in pediatric asthma patients.

Inter-society consensus for the use of inhaled corticosteroids in infants, children and adolescents with airway diseases

BACKGROUND

In 2019, a multidisciplinary panel of experts from eight Italian scientific paediatric societies developed a consensus document for the use of inhaled corticosteroids in the management and prevention of the most common paediatric airways disorders. The aim is to provide healthcare providers with a multidisciplinary document including indications useful in the clinical practice. The consensus document was intended to be addressed to paediatricians who work in the Paediatric Divisions, the Primary Care Services and the Emergency Departments, as well as to Residents or PhD students, paediatric nurses and specialists or consultants in paediatric pulmonology, allergy, infectious diseases, and ear, nose, and throat medicine.

METHODS

Clinical questions identifying Population, Intervention(s), Comparison and Outcome(s) were addressed by methodologists and a general agreement on the topics and the strength of the recommendations (according to the GRADE system) was obtained following the Delphi method. The literature selection included secondary sources such as evidence-based guidelines and systematic reviews and was integrated with primary studies subsequently published.

RESULTS

The expert panel provided a number of recommendations on the use of inhaled corticosteroids in preschool wheezing, bronchial asthma, allergic and non-allergic rhinitis, acute and chronic rhinosinusitis, adenoid hypertrophy, laryngitis and laryngospasm.

CONCLUSIONS

We provided a multidisciplinary update on the current recommendations for the management and prevention of the most common paediatric airways disorders requiring inhaled corticosteroids, in order to share useful indications, identify gaps in knowledge and drive future research.

2020 Focused Updates to the Asthma Management Guidelines: A Report from the National Asthma Education and Prevention Program Coordinating Committee Expert Panel Working Group

The 2020 Focused Updates to the Asthma Management Guidelines: A Report from the National Asthma Education and Prevention Program Coordinating Committee Expert Panel Working Group was coordinated and supported by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health. It is designed to improve patient care and support informed decision making about asthma management in the clinical setting. This update addresses six priority topic areas as determined by the state of the science at the time of a needs assessment, and input from multiple stakeholders:A rigorous process was undertaken to develop these evidence-based guidelines. The Agency for Healthcare Research and Quality's (AHRQ) Evidence-Based Practice Centers conducted systematic reviews on these topics, which were used by the Expert Panel Working Group as a basis for developing recommendations and guidance. The Expert Panel used GRADE (Grading of Recommendations, Assessment, Development and Evaluation), an internationally accepted framework, in consultation with an experienced methodology team for determining the certainty of evidence and the direction and strength of recommendations based on the evidence. Practical implementation guidance for each recommendation incorporates findings from NHLBI-led patient, caregiver, and clinician focus groups. To assist clincians in implementing these recommendations into patient care, the new recommendations have been integrated into the existing Expert Panel Report-3 (EPR-3) asthma management step diagram format.

Anti-inflammatory activity of SintMed65, an N-acylhydrazone derivative, in a mouse model of allergic airway inflammation

Asthma is a chronic, complex and heterogeneous inflammatory illness, characterized by obstruction of the lower airways. About 334 million people worldwide suffer from asthma, and these estimates, as well as the severity of the disease, have increased in the last decades. Glucocorticoids are currently the most widely used drugs in the treatment and control of asthma symptoms, but their prolonged use can cause serious adverse effects. N-acylhydrazone derivatives have been tested in pre-clinical studies in models of inflammatory diseases. Here we tested SintMed65 (N'-[(1E)-3-(4-nitrophenylhydrazono)]-(2E)-propan-2-ylidene-3,5-dinitrobenzohydrazide), a compound belonging to a novel class of immunosuppressive drugs, in a mouse model of allergic airway inflammation. BALB/c mice were sensitized previously and challenged with ovalbumin for five consecutive days and SintMed65 treatment was performed orally 1 h prior to challenge with ovalbumin. Administration of SintMed65, as well as the reference drug dexamethasone, reduced cellularity and the number of eosinophils in the bronchoalveolar fluid (BALF). SintMed65 also reduced the production of Th2 cytokines IL-4, IL-5 and IL-13 in the BALF, and IL-4, IL-10 and CCL8 gene expression in lung, compared to vehicle-treated mice. Importantly, a reduction in the number of leukocytes and in the mucus production in lungs of SintMed65-treated mice was found, compared to the vehicle-treated group. In contrast, IgE production was not significantly altered after treatment with SintMed65. Our results demonstrate that compound SintMed65 possesses anti-inflammatory characteristics, suggesting its therapeutic potential for the treatment of allergic diseases.
