Levels of intracellular HIV-DNA in patients with suppressive antiretroviral therapy
Bibliographic record
Abstract
OBJECTIVE: The objective of this study is to study factors associated with HIV-DNA levels in chronically infected patients on long-term suppressive antiretroviral therapy (ART). DESIGN: A cross-sectional, multicentre study of patients receiving ART for more than 3 years, HIV-RNA less than 50 copies/ml for more than 2 years and CD4 cell count more than 350 cells/μl. METHOD: Factors associated with low (<150) or high (>1000), compared with intermediate (150-1000 copies/10 PBMCs) levels of HIV-DNA were investigated using multinomial logistic regression. RESULTS: Five hundred and twenty-two patients who initiated ART during the chronic phase were included (71% male; median peak HIV-RNA: 4.88 log10 copies/ml, CD4 cell count nadir: 222 cells/μl). Median ART duration was 13 years [interquartile range (IQR) 7-17], viral suppression was 5.7 years (IQR 3.9-8.5) and 66% of the patients never experienced ART failure. Median HIV-DNA was 323 copies/10 PBMCs (IQR, 129-717) with low, intermediate and high levels observed in 28.3, 55.4 and 16.3%, respectively. In multivariable analysis, women were more likely to achieve a low level of HIV-DNA. Each additional year with suppressed HIV-RNA increased the likelihood of low level and decreased the likelihood of high level of HIV-DNA. Peak HIV-RNA higher than 5log10 was always associated with a decreased risk of low and an increased risk of high HIV-DNA. For patients with peak HIV-RNA lower than 5log10, past ART failure was associated with high level of HIV-DNA. CONCLUSION: Chronically HIV-infected patients with long-term suppressive ART can achieve low total HIV-DNA but one over six still presented HIV-DNA above 1000 copies/10 PBMCs despite long-term viral suppression.

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.
