Synovial fluid analysis of two groups of proteoglycan epitopes distinguishes early and late cartilage lesions.
(1992) In Arthritis and Rheumatism 35(4). p.385-390- Abstract
- OBJECTIVE:
To investigate whether fragmentation of proteoglycans in arthritis results in domains that have different levels of release from cartilage at different stages of the disease.
METHODS:
Two regions of the proteoglycan, the hyaluronan-binding region and the glycosaminoglycan-rich region of the core protein, were measured, by immunoassay, in knee joint synovial fluids of patients with rheumatoid arthritis or reactive arthritis.
RESULTS:
Synovial fluid concentrations of the glycosaminoglycan-rich region were highest in rheumatoid arthritis patients who had little cartilage damage as determined by radiography, whereas release of the hyaluronan-binding region predominated in patients with... (More) - OBJECTIVE:

RESULTS:
Synovial fluid concentrations of the glycosaminoglycan-rich region were highest in rheumatoid arthritis patients who had little cartilage damage as determined by radiography, whereas release of the hyaluronan-binding region predominated in patients with advanced cartilage destruction. In reactive arthritis, release of the glycosaminoglycan-rich region predominated.
CONCLUSION:
These findings indicate that the hyaluronan-binding region is initially retained in the tissue during the development of cartilage destruction. The combined analysis of these markers offers a new avenue for assessment of the degree of cartilage damage in arthritis.
