Abstract

fetched live from OpenAlex

<b>Introduction</b> As per GOLD strategy, ICS combined with a LABA and/or a LAMA is a first line choice to treat COPD patients (pts) at a high risk of exacerbations. However, there is widespread use of ICS in COPD pts who do not meet the GOLD criteria for its use. ICS use has been associated with systemic side effects such as suppression of hypothalamic pituitary-adrenal (HPA) axis function (decreased production of endogenous glucocorticosteriods). This reflects the systemic burden of ICS which can be associated with long-term consequences. Here, we present results for indacaterol/glycopyrronium (IND/GLY; LABA/LAMA) vs. salmeterol/fluticasone (SFC; LABA/ICS) in terms of HPA-axis function from the FLAME study. <b>Methods</b> FLAME was a 52-week, multicentre, double-blind study that randomised (1:1) moderate-to-very severe COPD pts (postbronchodilator FEV<sub>1</sub> ≥25 and &lt;60% predicted and ≥1 exacerbations in the previous year) to receive either IND/GLY 110/50µg o.d. or SFC 50/500µg b.i.d. HPA –axis function was assessed by measuring 24-h urine cortisol level in a subset of pts. <b>Results</b> Of 3362 randomised pts, 535 were included in the urine cortisol set. Median urine cortisol level decreased by 8.67% with SFC treatment, while the level increased by 1.42% with IND/GLY treatment from baseline at Week 52. Consistently, median cortisol/creatinine ratio reduced with SFC (by 10.39%) and increased with IND/GLY (by 5.62%) from baseline following 52-week treatment. <b>Conclusion</b> SFC but not IND/GLY treatment was associated with suppression of HPA-axis function in moderate-to-very severe COPD patients, confirming systemic effects of SFC.

Not 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.
