title: First-line DMARD choice in early rheumatoid arthritis--do prognostic factors play a role?
abstract: OBJECTIVE
  To examine if prognostic factors predict the choice of first DMARD for patients with RA.
  
  
  METHODS
  Details of 616 patients with early RA were collected from 16 centres in the UK Early Rheumatoid Arthritis Network (ERAN). Logistic regression was used to identify whether HAQ score, swollen joint count (SJC), nodules, RF, ESR, CRP and erosions on radiographs were associated with the choice of first DMARD treatment.
  
  
  RESULTS
  Of 616 patients, 547 (88%) were started on a DMARD, 253 (46%) on MTX, 230 (42%) on SSZ, 47 (9%) on other DMARD monotherapies and 17 (3%) on combination DMARD therapy (CoT). SSZ was started less frequently in patients with positive RF (P = 0.018; OR 0.59; 95% CI 0.38, 0.91) and high SJC (P = 0.02; OR 0.95; 95% CI 0.91, 0.99). MTX was favoured in patients with high SJC (P = 0.002; OR 1.07; 95% CI 1.02, 1.11). Non-prescription of DMARDs was associated with old age (P = 0.02; OR 0.98; 95% CI 0.96, 0.99) and low HAQ score (P = 0.009; OR 0.80; 95% CI 0.68, 0.95). None of the variables predicted CoT. All other variables and the hospital where the patient was treated were not independently associated with the choice of DMARD.
  
  
  CONCLUSIONS
  When choosing DMARD monotherapy in early RA, rheumatologists in ERAN seem to preferentially prescribe MTX for patients with a poor prognosis and SSZ for patients with good prognosis. No DMARDs were used in older patients or in those with a low HAQ.
