Predictive Value of Interleukin-7 Levels for Virological Response to Treatment in HIV-1-Infected Children
Bibliographic record
Abstract
We recently reported that interleukin-7 (IL-7), a potent stimulator of lymphopoiesis, is an independent predictor of virological response to antiretroviral therapy (ART) in HIV-1 infected adults. To determine if this cytokine also predicts treatment response in HIV-1-infected children, a longitudinal study was performed over 48 weeks in 36 treatment-naïve children vertically infected with HIV-1. Subjects who received treatment (n = 29) were stratified as complete virological responders (n = 12), partial virological responders (n = 11), or non-responders (n = 6), based on decline in viral load from baseline to week 48. Median plasma IL-7 levels at baseline were higher in complete responders (4.85 pg/mL, interquartile range [IQR] = 3.35-6.5) than in untreated controls (2.10 pg/mL, IQR = 1.50-3.50; p = 0.05). Linear regression analysis showed that baseline IL-7 levels were positively correlated with changes in HIV-1 viral load between baseline and week 24 (r = 0.40; p = 0.03) and between baseline and week 48 (r = 0.34; p = 0.07), but not with corresponding changes in CD4+ T-cell percentages and absolute counts. Collectively, these results indicate that IL-7 levels at baseline are predictive of virological but not immunological response to ART in children infected with HIV-1.

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.
