Primary care provider preferences for glucocorticoid management of acute asthma exacerbations in children

Analysis of Key Genes and miRNA-mRNA Networks Associated with Glucocorticoids Treatment in Chronic Obstructive Pulmonary Disease

Background

Some patients with chronic obstructive pulmonary disease (COPD) benefit from glucocorticoid (GC) treatment, but its mechanism is unclear.

Objective

With the help of the Gene Expression Omnibus (GEO) database, the key genes and miRNA-mRNA related to the treatment of COPD by GCs were discussed, and the potential mechanism was explained.

Methods

The miRNA microarray dataset (GSE76774) and mRNA microarray dataset (GSE36221) were downloaded, and differential expression analysis were performed. Gene Ontology (GO) function and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed on the differentially expressed genes (DEGs). The protein interaction network of the DEGs in the regulatory network was constructed with the STRING database, and the key genes were screened through Cytoscape. Potential downstream target genes regulated by differentially expressed miRNAs (DEMs) were predicted by the miRWalk3.0 database, and miRNA-mRNA regulatory networks were constructed. Finally, some research results were validated.

Results

① Four DEMs and 83 DEGs were screened; ② GO and KEGG enrichment analysis mainly focused on the PI3K/Akt signalling pathway, ECM receptor interaction, etc.; ③ CD2, SLAMF7, etc. may be the key targets of GC in the treatment of COPD; ④ 18 intersection genes were predicted by the mirwalk 3.0 database, and 9 pairs of miRNA-mRNA regulatory networks were identified; ⑤ The expression of miR-320d-2 and TFCP2L1 were upregulated by dexamethasone in the COPD cell model, while the expression of miR-181a-2-3p and SLAMF7 were downregulated.

Conclusion

In COPD, GC may mediate the expression of the PI3K/Akt signalling pathway through miR-181a-2-3p, miR-320d-2, miR-650, and miR-155-5p, targeting its downstream signal factors. The research results provide new ideas for RNA therapy strategies of COPD, and also lay a foundation for further research.

Quality improvement for paediatric asthma care in acute settings

PURPOSE OF REVIEW

This is a summative review of recent trends and novel programming integrated into various clinical settings (i.e. emergency departments, urgent care centres and paediatric clinics) to enhance the quality of care received by paediatric asthma patients Asthma is the most common chronic disease in paediatric patients and despite recognized national management guidelines, implementation and aftercare, especially in the emergency room, remain challenging.

RECENT FINDINGS

Outcome-based systematic quality improvement initiatives are described as well as evidence-based recommendations to enhance the education of providers, patients and caregivers.

SUMMARY

Many of the care initiatives described in the literature have been integrated into the emergency room. The authors feel some of these process improvements, such as pathway-based care, reducing time to delivery of medications, and personalized asthma education, may also be applicable and add value to clinical practice in additional community-based acute care settings such as urgent care centers and paediatric clinics.

Comparative effectiveness of oral dexamethasone vs. oral prednisolone for acute exacerbation of asthma: A randomized control trial

Background:

Acute exacerbation of asthma is a common condition leading to emergency visits. Prednisolone is a commonly prescribed drug in the standard management of acute exacerbation of asthma along with other drugs. This study was planned to see the efficacy of oral dexamethasone when compared with oral prednisolone in the management of acute exacerbation of asthma.

Methods:

A single-center pilot study in the form of randomized control trial was done by recruiting children aged 2–14 years diagnosed with acute asthma exacerbation with mild to moderate severity. A total of 88 patients received oral dexamethasone (0.3 mg/kg) in two doses 24 h apart, which was compared with 87 patients who received oral prednisolone (1 mg/kg) in two divided doses 12 h apart for 5 days. The patients were assessed at the time of admission (zero hour), at 4^th hour, and on the 5^th day by various parameters such as respiratory rate, use of accessory muscles, Pediatric Respiratory Assessment Measure (PRAM) score, peak expiratory flow rate (PEFR), 6-h admission stay, and rate of hospital admission.

Results:

Baseline demographic profile, clinical characteristics, comorbidities, indoor pollution, and use of Metered Dose Inhaler (MDI) among the two study groups were comparable. Six-hour emergency stay and rate of admission were significantly lower in the dexamethasone group (P < 0.05). Improvement in PRAM score, PEFR, use of accessory muscles, and respiratory rate was also better in dexamethasone group at the 4^th hour and 5^th day (P < 0.05). In addition, oral dexamethasone was shown to have less incidence of vomiting/gastritis than prednisolone (P < 0.05).

Conclusion:

Oral dexamethasone can be considered a reliable and better option as compared with prednisolone due to its faster action and minimal side effects.

Corticosteroid choice and clinical outcomes for asthma exacerbations in the primary care setting

OBJECTIVE

To evaluate clinical outcomes in young children with acute asthma exacerbations treated with prednisone/prednisolone versus dexamethasone in the primary care setting.

METHODS

Retrospective cohort study of children ages 3-9 years with a primary care clinic visit for asthma and an associated oral corticosteroid (OCS) prescription fill in the Colorado All Payers Claim Database between 2/2013-3/2019. This was a secondary analysis of a dataset extracted to analyze risk of future development of asthma in younger children. The primary outcome was subsequent ED visit or hospital admission for asthma within 2-14 days after the index clinic visit. Demographics and asthma health services characteristics were assessed. Multivariable logistic regression was used to estimate the association between type of OCS prescription filled within 1 day of the index clinic visit and the primary outcome.

RESULTS

There were 3236 index clinic visits for asthma for 1918 children during the study period. Sixty-two percent were male and 66% were 3-4 years old. Prednisone/prednisolone accounted for 84% of OCS prescriptions fills within 1 day of the index clinic visit. One percent visited the ED and 1% required hospital admission within 2-14 days. In multivariate analysis, there was no statistical association between type of OCS prescribed and the primary outcome (OR 0.82; 95% CI: 0.37-1.8).

CONCLUSIONS

There are no differences in clinical outcomes by type of OCS prescribed for acute asthma exacerbations in the primary care setting. Due to better adherence and side effect profile, primary care providers may consider to use dexamethasone as the preferred OCS.

Clinical factors associated with the use of dexamethasone for asthma in the pediatric emergency department

BACKGROUND

Dexamethasone is efficacious for the treatment of pediatric asthma exacerbations but is not specifically recommended by current national guidelines.

OBJECTIVES

To describe the factors associated with prescribed dexamethasone in a pediatric emergency department (PED) and upon patient discharge.

METHODS

Retrospective chart review of patients aged 2 to 18 years discharged home from a PED with a diagnostic code for asthma (J45x). Descriptive statistics are reported and binary logistic regression with generalized estimating equations was used to examine the demographic and clinical factors associated with dexamethasone use in the PED and upon discharge.

RESULTS

594 children contributed 690 visits for asthma. Two-thirds of patients received prednisone in the PED (n = 430; 62%). Among 260 children who received dexamethasone, 76% (n = 198) were prescribed a second dose for post-discharge administration. Multivariable models showed that patients triaged as most urgent had a 50% reduction in the odds of receiving dexamethasone in the PED (OR = 0.5; 95% CI = 0.28-0.87). Patients seen by a pediatrician (OR 4.2; 95%CI 2.1-8.3) and those triaged as urgent (OR 2.9; 95% CI = 1.8-7.8) were more likely to receive a single dose of dexamethasone.

CONCLUSIONS

Dexamethasone is less commonly used in the PED for asthmatic patients triaged as most urgent. Triage acuity and level of training were associated with single-dose treatment of asthma in those receiving dexamethasone. Further studies are needed to clarify the use of dexamethasone across the spectrum of asthma severity.

Assessment of family and internal medicine physicians knowledge and practice of bronchial asthma at Riyadh city

Background:

The prevalence of bronchial asthma (BA) is increasing in the Kingdom of Saudi Arabia. The knowledge and adherence to guidelines by physicians can play a major role in controlling asthma.

Aim:

To assess the knowledge and practice of family medicine and internal medicine physicians about BAat King Saudi University medical city in Riyadh, Kingdom of Saudi Arabia.

Methodology:

A cross-sectional survey study was conducted. All family and internal medicine physicians at King Khalid University Hospital were included. A total of 180 physicians participated. The questionnaire was developed according to the Global Initiative for Asthma (GINA) guideline to assess the knowledge and practice of physicians towards bronchial asthma, included questions (diagnosis, severity classification, management, and referral).

Results:

All participated physicians knowledge and practice level about BAwaslow; the average scores were around 50%. The comparison between family and internal medicine physicians' knowledge shows insignificant differences. The only exception is the management part; family medicine physicians show better results than internal medicine physicians. The years of experience and higher qualification show significant improvement in the level of the knowledge scores.

Conclusion:

The knowledge of physicians about the diagnosis, assessment of severity, management, and referral of BA was unsatisfactory. We recommend an adoption of a special asthma clinic for teaching, supervising, and managing purposes assigned to an expert consultant.
