Serum interleukin-6 and tumor necrosis factor-alpha concentrations in children with mycoplasma pneumonia
Abstract:
A prospective study was performed to assess the relationship among interleukin-6, tumor necrosis factor-alpha, C-reactive protein serum concentrations, and the severity of mycoplasma pneumonia in 49 children. Mycoplasma pneumonia was diagnosed by chest film and anti-Mycoplasma pneumoniae IgM antibody test. Serum concentrations of interleukin-6 and tumor necrosis factor-alpha were measured by using enzyme-linked immunosorbent assays. Interleukin-6 serum levels in mycoplasma pneumonia patients with fever for more than 3 days (41.98 +/- 67.46 [SD] pg/mL) were significantly higher than those in patients with fever < or = 3 days (10.01 +/- 11.74 pg/mL, p < 0.05). Interleukin-6 serum levels in those patients whose chest films revealed patchy consolidations or pleural effusion (58.11 +/- 92.19 pg/mL) were significantly higher than those in patients whose chest films revealed peribronchial interstitial infiltration (15.94 +/- 20.81 pg/mL, p < 0.05). The mean levels of serum tumor necrosis factor-alpha were not statistically significant in the different duration of fever and chest film findings. These results suggest that interleukin-6 serum concentration, rather than tumor necrosis factor-alpha, may be a potential indicator of the severity and outcome of mycoplasma pneumonia.
Insights
Interleukin-6 (IL-6) serum levels indicate mycoplasma pneumonia severity in children. Higher IL-6 concentrations correlate with prolonged fever and more severe lung findings, unlike tumor necrosis factor-alpha.
Area of Science:
- Pediatric Infectious Diseases
- Immunology
- Respiratory Medicine
Background:
- Mycoplasma pneumoniae is a common cause of community-acquired pneumonia in children.
- Understanding inflammatory markers can help assess disease severity and prognosis.
Purpose of the Study:
- To investigate the association between serum levels of interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), and C-reactive protein (CRP) with the clinical severity of mycoplasma pneumonia in children.
Main Methods:
- Prospective study of 49 children diagnosed with mycoplasma pneumonia.
- Diagnosis confirmed by chest X-ray and IgM antibody testing.
- Serum IL-6 and TNF-α levels measured using enzyme-linked immunosorbent assays (ELISAs).
Main Results:
- Children with fever lasting over 3 days showed significantly higher IL-6 levels compared to those with shorter fever duration (p < 0.05).
- Patients with patchy consolidations or pleural effusion on chest X-ray had significantly elevated IL-6 levels versus those with peribronchial infiltration (p < 0.05).
- Serum TNF-α levels did not show significant correlations with fever duration or radiographic findings.
Conclusions:
- Serum IL-6 concentration may serve as a potential biomarker for assessing the severity and predicting the outcome of mycoplasma pneumonia in pediatric patients.
- IL-6 appears to be a more sensitive indicator of disease severity than TNF-α in this context.
