Association of serum interleukin-17 level and Mycoplasma pneumoniae pneumonia in children: a systematic review and meta-analysis
Bibliographic record
Abstract
Background: Mycoplasma pneumoniae (M. pneumoniae) is a common pathogen of community-acquired pneumonia. Interleukin-17 (IL-17) plays a role in host defense and contributes to disease severity in infection. This present study aims to investigate the association between Mycoplasma pneumoniae pneumonia (MPP) and changes of IL-17 level in the serum of pediatric patients. Methods: The protocol has been registered in PROSPERO (CRD42023489451). A literature search was conducted in PubMed, EMBASE, Scopus, and Web of Science from inception to October 2023. A meta-analysis was performed to pool the mean difference (MD) with 95% confidence intervals (CIs) of IL-17 levels between patients and controls. Publication bias was assessed, and the risk of bias was evaluated using the Newcastle-Ottawa Scale (NOS). Results: Out of 207 records, 10 studies were included in the review and 9 studies were included in the meta-analysis. Of these, 7 studies compared IL-17 in general MPP patients with controls, 6 studies compared severe MPP patients with mild MPP patients. Serum IL-17 levels were significantly elevated in general MPP patients compared with control (MD =33.94 pg/mL, 95% CI: 24.66, 43.22 pg/mL, P=0.01, I2=99.07%; P=0.01). Subgroup analyses showed a difference in serum IL-17 levels treated by macrolide between patients and control (MD =83.96 pg/mL, 95% CI: 76.62, 91.29 pg/mL, P=0.01). In severe and mild MPP, the IL-17 levels were significantly increased (MD =19.08 pg/mL, 95% CI: 11.51, 26.65 pg/mL, P=0.01) and heterogeneity was appeared (I2=99.39%; P=0.01). For the risks of bias, two studies had a “high risk” in comparability domain, and the 7 studies were classified as “low risk” and “unclear risk”. Conclusions: Our meta-analysis revealed that serum IL-17 levels are significantly elevated in pediatric with general and severe MPP. IL-17 might be a potential biomarker or therapeutic target for pneumonia caused by M. pneumoniae.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
