Association of comorbidities and medications with risk of asthma exacerbation in pediatric patients: a retrospective study using Japanese claims data

Prediction of Asthma Exacerbations in Children

Asthma exacerbations are common in asthmatic children, even among those with good disease control. Asthma attacks result in the children and their parents missing school and work days; limit the patient's social and physical activities; and lead to emergency department visits, hospital admissions, or even fatal events. Thus, the prompt identification of asthmatic children at risk for exacerbation is crucial, as it may allow for proactive measures that could prevent these episodes. Children prone to asthma exacerbation are a heterogeneous group; various demographic factors such as younger age, ethnic group, low family income, clinical parameters (history of an exacerbation in the past 12 months, poor asthma control, poor adherence to treatment, comorbidities), Th2 inflammation, and environmental exposures (pollutants, stress, viral and bacterial pathogens) determine the risk of a future exacerbation and should be carefully considered. This paper aims to review the existing evidence regarding the predictors of asthma exacerbations in children and offer practical monitoring guidance for promptly recognizing patients at risk.

Effect of Bairui Granule on Inflammatory Mediators in Induced Sputum, Leukotriene C4, and EOS in Peripheral Blood of Children with Cough Variant Asthma

Objective

To study the effect of Hanchuan Zupa granule combined with conventional western medicine in the treatment of children with bronchial asthma.

Methods

98 cases in Fengrun District People's Hospital of Tangshan City from June 2018 to February 2021 were selected. The control group was given oxygen therapy, antibiotics, and aerosol inhalation of quick acting β 2 receptor agonist, glucocorticoid, and other conventional western medicine treatment, while the observation group was treated with Bairui granule on the basis of the control group. The course of treatment of the two groups was 1 week.

Results

After treatment, the levels of sputum IL-4, IL-17, neu, and ECP in the two groups decreased, and the observation group was lower than the control group (P < 0.05). The levels of EOS, CXCR4, LTB4, and SDF-1 in peripheral blood of the two groups were lower than those in the control group (P < 0.05). The daytime cough, night cough, and TCM syndrome scores of the two groups were decreased, and the observation group was lower than the control group (P < 0.05).

Conclusion

Bairui granule combined with conventional western medicine in the treatment of children with bronchial asthma, the curative effect is worthy of affirmation, can effectively improve cough symptoms, reduce EOS, CXCR, LTB4, SDF-1 levels, inhibit airway inflammation, and has good clinical application value.
