Abstract

Objective: To assess the relationship between inflammation and joint destruction in rheumatoid arthritis (RA) patients who have not responded clinically to treatment. Methods: Changes from baseline to week 54 in clinical variables and measures of radiographic progression were compared between patients who received infliximab (3 mg/kg or 10 mg/kg every 4 or 8 weeks) plus methotrexate (MTX) and those who received MTX plus placebo in the Anti–Tumor Necrosis Factor Trial in RA with Concomitant Therapy trial. Results: At week 54, patients who did not show 20% improvement by American College of Rheumatology criteria (ACR20 nonresponders) while receiving infliximab plus MTX exhibited mild but statistically significant improvement in clinical variables, including the 28‐joint Disease Activity Score (DAS28) (P < 0.001), tender joint count (P = 0.014), swollen joint count (P < 0.001), and C‐reactive protein (CRP) level (P < 0.001). Whereas the clinical and CRP changes among ACR20 nonresponders to infliximab plus MTX were small and much lower than among ACR20 responders to this treatment, radiographic progression among ACR20 nonresponders to infliximab plus MTX was significantly inhibited (P < 0.001) compared with ACR20 nonresponders to MTX plus placebo. Radiographic progression was much greater in patients receiving MTX plus placebo than in patients receiving infliximab plus MTX, irrespective of ACR response status (mean change in modified Sharp/van der Heijde score 6.0 in ACR20 responders and 7.2 in ACR20 nonresponders in the MTX plus placebo–treated group, versus 0.1 in ACR20 responders and 1.2 in ACR20 nonresponders in the infliximab plus MTX–treated group). Furthermore, among patients who were ACR20 nonresponders through week 54, patients who were DAS nonresponders at weeks 30 and 54, and patients without any improvement in individual clinical variables, those receiving infliximab plus MTX still demonstrated inhibition of structural damage that was statistically significant compared with inhibition in patients who received MTX plus placebo (P < 0.05 to P < 0.001). Conclusion: Even in patients without clinical improvement, treatment with infliximab plus MTX provided significant benefit with regard to the destructive process, suggesting that in such patients these 2 measures of disease are dissociated.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
