Infliximab is Associated with Improvement in Arterial Stiffness in Patients with Early Rheumatoid Arthritis — A Randomized Trial
Bibliographic record
Abstract
OBJECTIVE: To determine the efficacy of methotrexate (MTX) with infliximab (IFX) compared with MTX alone in the prevention of atherosclerosis and arterial stiffness in patients with early rheumatoid arthritis (RA). METHODS: A randomized, open-label study in which early RA patients with active disease were treated with MTX alone (n = 20) and MTX plus IFX (n = 20) for 6 months. Patients were assessed every 3 months. Patients from the MTX-alone group who failed to achieve 28-joint Disease Activity Score remission (DAS28 ≤ 2.6) at 6 months were permitted to escape to open-label IFX. Intima-media thickness (IMT), pulse wave velocity (PWV), and augmentation index (AIx) were measured at baseline, 6 months, and 12 months. RESULTS: At 6 months, there was a significantly greater reduction in PWV in the MTX-alone group (0.18 ± 1.59 m/s) compared with the MTX plus IFX group (-0.78 ± 1.13 m/s; p = 0.044), accompanied by significantly greater reduction in patient's global assessment, number of swollen joints, C-reactive protein, and DAS28 in the MTX plus IFX group compared to the MTX-alone group. The changes in IMT and AIx were similar between the 2 groups. At 12 months, there was a trend favoring early combination treatment with regard to the reduction in PWV (p = 0.06). CONCLUSION: MTX plus IFX causes a more significant reduction in PWV than MTX alone in patients with early RA after 6-month treatment, and further improvement may be achieved in patients who continued on longterm tumor necrosis factor-α blockers, suggesting that early, effective suppression of inflammation may prevent progression of atherosclerosis by improving vascular function.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
