The effects of iguratimod combined with methotrexate and hydroxychloroquine on bone mineral density in patients with rheumatoid arthritis.

ABSTRACT

In this study, we aimed to explore the effects of iguratimod (IGU) combined with methotrexate (MTX) and hydroxychloroquine (HCQ) on bone mineral density (BMD) in patients with rheumatoid arthritis (RA). 76 patients who received IGU combined with MTX and HCQ were included in this retrospective study. After 48 weeks treatment of IGU combined with MTX and HCQ, the BMD at the L1-L4 (p <0.01), left femoral neck (p <0.01) and left total hip (p <0.01) were significantly increased. Especially, the BMD at left femoral neck was significantly increased from baseline to week 24 (p <0.05). With regard to inflammatory reaction, there were statistically significant reductions in the RF (p <0.05), CRP (p <0.05), ESR (p <0.01), anti-CCP (p <0.01) from baseline to week 48. The most common adverse events were gastrointestinal reaction and transaminase elevation. The combination of IGU, MTX and HCQ could significantly improve the BMD and restrain inflammatory reaction. No additional adverse events were noticed in our research. This study provides valuable information for treatment of osteopenia in patients with RA.
