PG - 104-8 LID - 10.1111/j.1440-1797.2007.00845.x [doi] AB - BACKGROUND: It is recognized that matrix metalloproteinase-3 (MMP-3) is abundantly expressed in active rheumatoid synovium, and that serum level of MMP-3 is a useful marker for diagnosis of rheumatoid arthritis and for evaluation of prognosis in joint destruction. Little is known about serum MMP-3 levels in haemodialysis (HD) patients, and thus, the association between serum MMP-3 and dialysis-related amyloidosis (DRA) has yet to be elucidated. METHODS: Serum levels of MMP-3 were measured by enzyme immunoassay in 150 HD patients, 90 without DRA and 60 with DRA, before HD. Simple regression analysis was performed to investigate the relationship between serum level of MMP-3 and clinical parameters, including age, HD duration, C-reactive protein and beta2 microglobulin (BMG). RESULTS: Serum levels of MMP-3 were significantly higher in HD patients with DRA than in HD patients without DRA (258.2 +/- 118.1 vs 201.5 +/- 98.4 pg/mL, P = 0.0017), and both levels were significantly higher than those of healthy subjects (45.6 +/- 13.4 pg/mL, P < 0.0001). Serum MMP-3 levels significantly correlated with serum levels of BMG (r = 0.197, P = 0.0164) and HD duration (r = 0.168, P = 0.0427). Moreover, serum MMP-3 levels significantly correlated with serum BMG levels in HD patients without DRA (r = 0.341, P = 0.0012), but not in HD patients with DRA. CONCLUSION: Our results suggest that matrix metalloproteinase activity increases in HD patients, which may be associated with BMG and DRA.
