  Purpose
In this project the investigators decide to evaluate the efficacy and safety of half dose mabthera (it means 500 mg infusion two weeks apart) in conventional drug resistant cases of rheumatoid arthritis. The investigators choose this drug because the use of anti-TNF drugs limited in the investigators refractory patients as the first line drugs because of its cost.

Primary Outcome Measures:
  • change in 28-joint disease activity index( DAS28) [ Time Frame: Study duration was 6 months and the subjects were assessed for DAS 28 change at baseline, after 2 , 16 and 24 weeks. ]
    disease activity score 28 formula which caculates based the number of tenderness and swelling of 28 joints and also ESR)

  • Change in European league against rheumatism(EULAR) response criteria [ Time Frame: Change in EULAR 2,16,24 weeks ]

Secondary Outcome Measures:
  • Rituximab side effects [ Time Frame: 0,2,16,24 weeks ]
    side effects like infusion reaction , paresthesia, itching,hypertension or hypotension,headache and infection.
