title: A double blind placebo controlled trial of azathioprine in the treatment of primary Sjögren's syndrome.
abstract: OBJECTIVE
  To establish whether there is a place for low dose azathioprine (AZA) as a disease modifying agent in patients with uncomplicated primary Sjögren's syndrome (SS).
  
  
  METHODS
  Twenty-five patients with primary SS were entered into a double blind, placebo controlled trial of AZA (1 mg/kg/day) for a period of 6 months.
  
  
  RESULTS
  Six patients, all receiving active drug, withdrew because of side effects. There was no significant change in disease activity variables when measured clinically, serologically, or histologically.
  
  
  CONCLUSIONS
  This trial suggests that low dose AZA does not have a role as a disease modifying agent in SS.
