- Objectives: Evaluation of mesenchymal stem cell therapy effects on cellular and humoral immune responses in refractory rheumatoid arthritis (RA) patients.
- Design: This study has been performed as a phase 1 clinical trial.
- Setting and conduct: Autologous bone marrow derived mesenchymal stem cells were obtained by bone marrow aspiration and cultured in Minimum Essential Medium-Alpha (MEM-alpha) for 4 weeks in standard clean room and then transfused to RA patients intravenously.
- Participant's major eligibility criteria is as follows: Ten refractory rheumatoid arthritis patients who show resistance to non biological Disease-modifying antirheumatic drugs (DMARDs) after 6 to 12 months have been enrolled in this study.
- Intervention: A single dose of intravenous autologous bone marrow derived mesenchymal stem cells have been administered into patients with resistance to non-biological DMARDs.
- Main outcome measures (variables): Finding of mesenchymal stem cell therapy effects on the cellular and humoral immune responses and evaluation of the effect of chemokines in homing of immune cells following the intervention.
