Randomized,controlled clinical trial comparison of sodium hyaluronate versus celecoxib in knee osteoarthritis patients / 实用医学杂志

ABSTRACT

Objective To compare the effects of sodium hyaluronate (SH) and celecoxib (CO) administration on the treatment of knee osteoarthritis (OA) and to investigate their influences on levels of uPA and MMP-3 in synovial fluid. Methods One hundred and thirty-six knee osteoarthritis (OA) patients from January 2010 to October 2011 were randomly enrolled into two groups the SH group and the CO group. In the SH group, patients were injected with 2 mL sodium hyaluronate intra articulation once a week for 5 weeks. In the CO group , patients were given oral administration of celecoxib daily at a dosage of 200 mg for 5 weeks. Before and at 1 ,6 months after treatment, Lequesne′s index and VAS-pain were detected to assess the clinical results of these two drugs. The levels of uPA and MMP-3 in synovial fluid were measured by using ELISA assay. Results All patients were followed up for 6 months to 12 months. The Lequesne′s index and VAS-pain score were lowered at 1 and 6 moths after treatment in both the SH group and the CO group(P0.05). Dramatic reduction of the levels of uPA and MMP-3 in synovial fluid were observed in the SH group after treatment(P0.05). Conclusion The redueced levels of uPA and MMP-3 in synovial fluid after treatment of sodium hyaluronate may contribute to its longer-lasting effect than that of celecoxib. Therefore , the combination of sodium hyaluronate with celecoxib may lead to better therapeutic effect on OA patients.
