Effect of nimesulide on the serum levels of hyaluronan and stromelysin-1 in patients with osteoarthritis: a pilot study.

This prospective preliminary single-blind study was conducted in patients suffering from osteoarthritis (OA) and requiring non-steroidal anti-inflammatory drugs (NSAIDs) to determine to what extent nimesulide (200 mg/day) and ibuprofen (1200 mg/day) could induce significant changes in the serum levels of matrix metalloproteinase-3 (MMP-3), tissue inhibitor-1 of MMPs (TIMP-1), hyaluronan (HA) and YKL-40 after a therapeutic time period of 28 days. The four biochemical parameters were assessed by using immunoassays. Nimesulide significantly reduced the serum levels of both HA and MMP-3, whereas ibuprofen increased moderately but significantly the serum concentrations of MMP-3 and had no effect on the serum concentrations of HA. The two NSAIDs were unable to change the serum levels of both TIMP-1 and YKL-40. These results suggest that nimesulide might have a favourable effect on the metabolism of OA joints.
