A Short Burst of Oral Corticosteroid for Children with Acute Asthma: Is There an Impact on Immunity?
Bibliographic record
Abstract
Background: We wished to examine the impact of a short course of oral corticosteroids on the immune function of children with acute asthma and explore the mechanism of immune suppression, if any. Methods: We conducted a prospective cohort study of children aged 3–17 years presenting with acute asthma to the emergency department. The exposure of interest was a short course of systemic corticosteroids. In emergency department, corticosteroid-treated and nonexposed children were immunized with 3 antigens, namely, a neoantigen (Bacteriophage φX 174) and 2 recall antigens (diphtheria and tetanus). After 5 ± 1 weeks, children were reimmunized with Bacteriophage φX 174. Antibody titers were measured 1, 2 (peak), and 5 weeks after the primary immunization, and 1 week (peak) after the secondary one. Results: We enrolled 41 children, 27 treated with and 14 unexposed to oral corticosteroids. Corticosteroid-treated children displayed an 85% lower adjusted total (IgG and IgM) peak titers to the primary Bacteriophage immunization compared to controls [ratio of geometric means (95% confidence interval): 15% (5% to 43%)]. There were no group differences in the rise of diphtheria or tetanus antibodies. After the secondary Bacteriophage immunization, corticosteroid-treated patients showed no significant group difference in peak total titers [ratio of geometric means (95% confidence interval): 1.84% (0.66%, 5.10%)], amplification and absolute, and percent IgG titers as compared to unexposed children. Conclusions: In children with acute asthma, a short course of oral corticosteroids may be associated with depressed immune response to a new antigen, with recovery within 6 weeks and no apparent impact on response to known antigens.

How this classification was reachedexpand
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.
