Serum Col3-4: A new type III and IV collagen biochemical marker of synovial tissue turnover in patients with rheumatoid arthritis
The objective of this study was to develop a serum biochemical marker of the degradation of type III and IV collagens, as an index of synovium turnover, and evaluate its performance in patients with rheumatoid arthritis (RA). An enzyme-linked immunosorbent assay for serum synovial collagen fragments...

description | The objective of this study was to develop a serum biochemical marker of the degradation of type III and IV collagens, as an index of synovium turnover, and evaluate its performance in patients with rheumatoid arthritis (RA). An enzyme-linked immunosorbent assay for serum synovial collagen fragments (Col3-4) was developed using an antibody recognizing a specific sequence from human type III collagen, which shares 70% homology with type IV collagen. Immunohistochemistry was performed to localize Col3-4 and the matrix metalloprotease MMP-9 which is upregulated in RA synovial fibroblasts in the synovial tissue from a RA patient. Serum Col3-4 was measured in patients with RA (n = 66, 73% women, mean age 62 years, median disease activity score 28 with erythrocyte sedimentation rate (DAS28-ESR) 2.6) and in sex and age matched healthy controls (n = 70, 76% women, mean age 59 years). Col3-4 immunoassay demonstrated adequate analytical performances and recognized a circulating neoepitope resulting from the cleavage of type III and IV collagens. In RA synovium tissue, Col3-4 fragments were localized in the lining layer where destructive fibroblasts are present and around blood vessels rich in type IV collagen. MMP-9 colocalized with Col3-4 staining and efficiently released Col3-4 fragments from type III and type IV collagen digestion. Serum Col3-4 was markedly increased in patients with RA (+240% vs controls, p < 0.0001) and correlated with DAS28-ESR (r = 0.53, p < 0.0001). Patients with RA and active disease (DAS28-ESR > 3.2, n = 20) had 896% (p < 0.0001) higher levels than subjects with low activity (n = 46). Serum Col3-4 is a specific and sensitive biochemical marker reflecting MMP- mediated type III and IV collagen degradation from synovial tissue. Serum Col3-4 levels are markedly increased in patients with RA, particularly in those with active disease, suggesting that it may be useful for the clinical investigation of RA. |
