Insights
Inhaled corticosteroids significantly improved lung function and reduced symptoms in children with wheezing and Mycoplasma pneumoniae (MP) or Chlamydia pneumoniae (CP) infections, compared to antibiotics alone.
Area of Science:
- Pediatric Pulmonology
- Infectious Diseases
- Respiratory Medicine
Background:
- Wheezing in children is often associated with Mycoplasma pneumoniae (MP) and Chlamydia pneumoniae (CP) infections.
- Identifying children at high risk for persistent asthma is crucial for early intervention.
Purpose of the Study:
- To evaluate lung function changes in wheezing children with MP/CP infections based on treatment.
- To assess the efficacy of inhaled corticosteroids (ICS) in children with significant wheezing at high risk for childhood asthma.
Main Methods:
- A randomized controlled trial involving 54 children with wheezing and documented MP/CP infection.
- Children were assigned to receive either inhaled fluticasone propionate plus macrolides or macrolides alone.
- Lung function, daily symptom scores (DSS), and symptom-free days (SFD) were monitored over 16 weeks.
Main Results:
- The group receiving ICS showed significant improvement in DSS and SFD compared to the control group.
- Pulmonary function tests indicated significant improvement in the ICS group.
- Treatment with ICS and macrolides was more effective than antibiotics alone in managing wheezing symptoms and improving lung function.
Conclusions:
- Inhaled corticosteroids should be strongly considered for children experiencing wheezing with documented MP or CP infections.
- Early intervention with ICS can mitigate persistent respiratory symptoms and improve lung function in at-risk children.
- This study highlights the benefit of ICS in managing pediatric wheezing associated with specific microbial infections.
Abstract:
Aims of this study were: to evaluate changes in lung function in wheezing children with detected MP and CP infection according to treatment; to measure the response to inhaled corticosteroids in children with significant wheezing who were selected as having a high risk of progressing into childhood asthma. 54 children were randomly assigned 2:1 into 2 groups-the main group (36 patients), in which inhaled corticosteroids were administered, and the control group (18 patients), without inhaled corticosteroids. Serum IgE levels were determined using the ELISA (reagents: IBL-Hamburg). Serologic studies were performed by the ELISA for IgM and IgG antibodies to MP and for IgG and IgA antibodies to CP (reagents: ImmunoLISA, Orgenics, Israel) on the Hiperion MRIII (USA). Pulmonary function testing was done with SpiroLab II (DEGO GmbH, Medizin-Elektronik, Germany). The patients of both groups were administered macrolides: azitromycin during five days. Patients of the first group received inhaled fluticasone propionate 125 mg twice daily. The parents were asked to record symptoms. Each symptom (wheezing, cough, and shortness of breath) were scored on a scale of 0 to 3--daily symptom score (DSS). Scores were calculated every 4 weeks for a total treatment period 16 weeks. The days within each period on which the DSS equalled zero were pointed as symptom free days (SFD). It had been shown an significant improvement in DSS, an increase in SFD and significant improvement of the lung functions following the treatment with inhaled fluticasone and macrolide in children with wheezing and documented MP or CP infection, compared to control group treated only with antibiotics. In conclusion, the use of ICS should be seriously considered in children with wheezing and the risk of persisting symptoms.
