Quintupling or quadrupling inhaled glucocorticoids to prevent asthma exacerbations?

Correlation Meta-Analysis of the Efficacy of Inhaled Corticosteroids in Children with Asthma Based on Smart Medical Health

Children are the reserve force for national construction, and children's health is now being paid more and more attention. In today's childhood asthma treatment, many are based on the treatment of common cough, and there is no strict division with asthma. Importantly, the efficacy of inhaled corticosteroids in the treatment of childhood asthma has been extensively studied in the medical community. However, there is no clear explanation for its specific efficacy and role. Research on childhood asthma has always been a key topic in medicine. This article aims to conduct a meta-analysis of the correlation between inhaled corticosteroids and asthma in children. This article proposes a more scientific literature screening strategy, which can achieve a higher accuracy rate for meta-analysis. It combines the intelligent medical health system in the analysis of children's asthma to assist in the analysis of curative effects. Such analysis also provides reference significance for related research. The experimental results indicate that inhaled corticosteroids have a good effect on childhood asthma. As the concentration of inhaled glucocorticoid increases, the effect will be better. Specifically, if the concentration is increased by 10%, the effect will be about 15% better, but there are corresponding side effects.

Increased versus stable dose of inhaled corticosteroids for asthma exacerbations: A systematic review and meta-analysis

BACKGROUND

Increasing the dose of inhaled corticosteroids (ICS) is commonly used at early signs of loss of asthma control. However, the potential benefits and harms of this strategy remain unclear. We performed a systematic review and meta-analysis to compare increased dose with stable dose of ICS among adults and children with asthma.

METHODS

We searched MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials from inception to August 02, 2018. Randomized clinical trials comparing increased doses vs stable doses of ICS for home management of asthma exacerbations in adults or children were included.

RESULTS

The analyses included 8 trials totalling 3866 patients. Four trials were judged as low risk of bias, three were unclear risk, and one was ranked as high risk. Increased dose of ICS was associated with a significantly reduced risk of treatment failure compared with stable dose (OR 0.82, 95% CI 0.70-0.97, I²  = 6%; 314 (281 to 351) vs 358 events per 1000 patients; moderate-quality evidence). There was no significant difference in unscheduled physician visits or hospital admission between increased or stable dose of ICS. However, increased dose of ICS increased the risk of non-serious adverse events (OR 3.50, 95% CI 1.93-6.35, I²  = 0%) but not serious adverse events.

CONCLUSIONS

Current evidence of moderate quality supports increasing the dose of ICS as part of a self-initiated action plan to reduce risk of requiring a course of systemic corticosteroids in people with an asthma exacerbation. However, we did not find evidence for an impact on hospital admissions or unscheduled physician visits, and increased ICS dose increased risk of non-serious adverse events.
