ModerateRheumatoid ArthritisBoolean Remission Predicts ProgressionSCE Rheumatology

A 55-year-old woman with rheumatoid arthritis is assessed 6 months after treatment initiation. Her 28-joint tender joint count is 1, swollen joint count is 0, C-reactive protein is 4 mg/L and patient global assessment is 18 mm on a 100-mm visual analogue scale. She therefore meets the revised ACR/EULAR Boolean 2.0 remission criteria. Which statement best describes the implication for her subsequent radiographic outcome?

Correct answer: A — She has an increased likelihood of radiographic non-progression, although progression is not completely excluded

Explanation lettering: D = shown as B · E = shown as C · C = shown as D · B = shown as E

The correct answer is A. The tender and swollen joint counts, CRP and patient global assessment satisfy Boolean 2.0 remission. In validation data, achieving this state at 6 months was associated with a substantially increased likelihood of later radiographic non-progression and good physical function. It is prognostic rather than absolute: some patients may still develop structural damage despite clinical remission. B is incorrect because Boolean remission predicts radiographic as well as functional outcomes. C and D contradict the observed association between stringent remission and reduced structural progression. E is incorrect because DAS28 remission is not required; historically, DAS28-based definitions were less stringent and predicted good radiographic outcomes less well than Boolean or index-based ACR/EULAR definitions.
