Insights
The Asthma Predictive Index (API) and nitric oxide (NO) levels can identify children at high risk for developing asthma, particularly those with multifactorial wheezing. Early measurement aids in predicting asthma formation in young children.
Area of Science:
- Pediatrics
- Respiratory Medicine
- Clinical Diagnostics
Background:
- Recurrent wheezing in children presents diagnostic challenges.
- Identifying early markers for asthma development is crucial for timely intervention.
- Different phenotypes of wheezing may have varying asthma progression rates.
Purpose of the Study:
- To investigate the Asthma Predictive Index (API) for predicting asthma.
- To evaluate the predictive value of quantitative changes in nitric oxide (NO) levels.
- To analyze these markers in children with recurrent wheezing of different phenotypes.
Main Methods:
- A cross-sectional clinical study involving 120 children aged 5-7 years with wheezing syndrome.
- Assessment of Asthma Predictive Index (API) response rates across different wheezing phenotypes.
- Measurement of fractional exhaled nitric oxide (FeNO) levels and correlation with API results.
Main Results:
- A 77% positive API response in 65% of multifactorial wheezing patients indicated high asthma probability.
- Episodic wheezing patients showed a 59% positive API response (28% prevalence).
- Elevated NO levels (27.8±0.71) were observed in 27.5% of multifactorial wheezing patients, correlating with a 77% positive API response; API demonstrated 81% sensitivity and 93% specificity.
Conclusions:
- API and NO measurements are valuable tools for early asthma risk identification in children.
- Early assessment is particularly important for children with multifactorial wheezing.
- These markers can help identify children with a high probability of developing asthma.
Abstract:
The study was aiming at investigation of Asthma Predictive Index (API) and predictive value of quantitative changes in nitric/nitrogen oxide (NO) in children with recurrent wheezing of different phenotypes. An observing cross-sectional clinical study where 120 patients 5 to 7 years of ages with wheezing syndrome were involved has been conducted. In the group of patients with multifactorial wheezing, 77%-positive results revealed in 65% of patients indicated to high probability of asthma formation. 59%-positive response to the API index prevailed in patients with episodic wheezing (28%). 77%-positive response sensitivity was 81% and specificity -93%, respectively. The increase in NO concentration (27.8±0.71) was fixed in 27.5% of patients with multifactorial wheezing, especially at 77% positive response to the API index. Measurement of API index and NO levels at early ages to reveal the contingent with high probability of asthma formation, especially in young children with multifactorial wheezing is of great importance.
