title: Efficacy of additive DMARD therapy in patients with rheumatoid arthritis. Double blind controlled trial using bucillamine and placebo with maintenance doses of gold sodium thiomalate.
abstract: OBJECTIVE
  To examine the efficacy of the addition of small doses of additional disease modifying antirheumatic drugs (DMARD) to ongoing DMARD treatment [additive DMARD therapy (ADT)].
  
  
  METHODS
  A 3-month prospective, double blind, randomized, placebo controlled study was performed using either 100 mg/day of bucillamine (Buc) or an inactive placebo (P1). Two groups of 12 patients each who had experienced an insufficient benefit from gold sodium thiomalate (GSTM) alone were enrolled in the study.
  
  
  RESULTS
  The addition of Buc proved more beneficial than P1 regarding improvement in disease activity (p = 0.0032) and drug usefulness (p = 0.0025). A significant within group improvement was observed in joint swelling count, the Lansbury activity index, erythrocyte sedimentation rate and C-reactive protein. However, the difference in the clinical variables between the 2 groups was minimal.
  
  
  CONCLUSIONS
  The usefulness of ADT was suggested by this trial; however, further confirmation by additional studies is still needed.
