Effect of obesity on treatment outcome of asthma predictive index-positive infants and young children with wheezing / 中国当代儿科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the effect of obesity on the treatment outcome of asthma predictive index (API)-positive infants and young children with wheezing.</p><p><b>METHODS</b>A total of 208 API-positive infants and young children with wheezing were enrolled. According to the Kaup index, the patients were divided into an obese group (n=93) and a non-obese group (n=115). The patients were given multimodality therapy in an acute episode of wheezing and aerosol inhalation of inhaled corticosteroid (ICS) budesonide suspension in the remission stage. The dose of ICS was adjusted according to clinical control. The patients were treated for 6 months, and were followed up at 2 weeks after treatment and once per month afterwards.</p><p><b>RESULTS</b>At 2 weeks and 1 month after treatment, the obese group had significantly lower remission rates of clinical symptoms than the non-obese group (35.5%/75.3% vs 53.0%/87.8%; P<0.05). Compared with the non-obese group, the obese group had significantly higher incidence rates of wheezing at 3 and 6 months after treatment and a significantly higher proportion of patients who visited the emergency service or were hospitalized due to wheezing within 6 months (P<0.05).</p><p><b>CONCLUSIONS</b>Obesity can inhibit the response to ICS treatment in API-positive infants and young children with wheezing.</p>
