Effects of Fluticasone on Systemic Markers of Inflammation in Chronic Obstructive Pulmonary Disease
Bibliographic record
Abstract
Systemic inflammation is present in chronic obstructive pulmonary disease (COPD), which has been linked to cardiovascular morbidity and mortality. We determined the effects of oral and inhaled corticosteroids on serum markers of inflammation in patients with stable COPD. We recruited 41 patients with mild to moderate COPD. After 4 weeks during which inhaled corticosteroids were discontinued, patients were assigned to fluticasone (500 mcg twice a day), oral prednisone (30 mg/day), or placebo over 2 weeks, followed by 8 weeks of fluticasone at 500 mcg twice a day and another 8 weeks at 1,000 mcg twice a day. Withdrawal of inhaled corticosteroids increased baseline C-reactive protein (CRP) levels by 71% (95% confidence interval [CI], 16-152%). Two weeks with inhaled fluticasone reduced CRP levels by 50% (95% CI, 9-73%); prednisone reduced it by 63% (95% CI, 29-81%). No significant changes were observed with the placebo. An additional 8 weeks of fluticasone were associated with CRP levels that were lower than those at baseline (a 29% reduction; 95% CI, 7-46%). Inhaled and oral corticosteroids are effective in reducing serum CRP levels in patients with COPD and suggest their potential use for improving cardiovascular outcomes in COPD.

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.
