Abstract
Circulating hyaluronan originating from the synovial membrane and circulating proteoglycan released from cartilage were determined by specific assays in patients with osteoarthritis (OA), rheumatoid arthritis (RA), reactive arthritis or juvenile chronic arthritis (JCA). Elevated hyaluronan concentrations were found in OA and RA, suggesting proliferation of the synovial membrane in both diseases. The proteoglycan concentrations were highest in OA and polyarticular JCA indicating increased turnover of cartilage matrix. The concentrations of the macromolecules did not correlate except in the group with JCA. Serum concentrations of hyaluronan and proteoglycan thus differ between disease groups and may reflect different aspects of the arthritic process.
