The activity of galactosylhydroxylysyl glucosyltransferase (S-GGT) and concentration of the amino-terminal propeptide of type III procollagen, measured with two different radioimmunoassays, S-Pro(III)-N-P and S-Fab, were determined in the sera of 209 patients with various rheumatic diseases. The mean values for all these three assays were elevated in the patients with rheumatoid arthritis, whereas only the mean value for S-GGT was elevated in osteoarthrosis. The mean S-GGT but not S-Pro(III)-N-P or S-Fab was also elevated in psoriatic arthritis, ankylosing spondylitis and systemic lupus erythematosus. S-GGT correlated significantly both with S-Pro(III)-N-P and S-Fab in the pooled group of all the patients and in the cases of rheumatoid arthritis and psoriatic arthritis, and also with S-Fab in the cases of osteoarthrosis. S-Pro(III)-N-P and S-Fab correlated with each other in every disease group. The ratio S-Fab:S-Pro(III)-N-P was significantly higher in the patients with osteoarthrosis, ankylosing spondylitis and systemic lupus erythematosus than in those with rheumatoid arthritis. The data indicate that definite changes can be seen in the values of serum markers of collagen metabolism in rheumatoid arthritis, psoriatic arthritis, osteoarthrosis, ankylosing spondylitis and systemic lupus erythematosus, the most sensitive indicator being S-GGT.

Measurement of the aminoterminal type III procollagen peptide in serum has been suggested as a marker of the biosynthesis of collagen type III, a major connective tissue component in repair processes. In the present study the propeptide level correlated with the inflammatory synovial mass in rheumatoid arthritis and osteoarthritis. This implies that the propeptide level reflects the collagen type III synthesis occurring in the synovial repair processes, whether they were caused by inflammatory or degenerative rheumatic disorders. Physical activity did not enhance the transition of the propeptide from the synovial fluid or the inflamed synovial membrane to the blood. Normal serum propeptide values were observed in most patients with ankylosing spondylitis and degenerative diseases of the spine. This may reflect the lower amount of inflammatory tissue in these diseases and hence the sensitivity of the assays.

Serum levels of hyaluronic acid (HA) and the amino-terminal type III procollagen peptide (NP-III-P) were determined simultaneously by specific immunoassays in patients with rheumatoid arthritis (n = 41), osteoarthritis (n = 43), ankylosing spondylitis (n = 7), psoriatic arthritis (n = 6), and reactive arthritis (n = 6). Increased serum levels of both HA and NP-III-P, were found in rheumatoid arthritis and - although less pronounced - in osteoarthritis, differing significantly from age- and sex-matched controls (n = 77). Furthermore, patients suffering from active rheumatoid arthritis showed higher serum levels of both antigens than patients with inactive disease, and significant correlations were found in rheumatoid arthritis between acute phase plasma proteins, HA and NP-III-P, respectively. In contrast, determination of low molecular weight fractions of NP-III-P by Fab- assay proved not to be useful in regard to clinical application. No significant effects of anti-inflammatory treatment were evident in any of the parameters. In rheumatoid patients, the serum concentrations of HA were found to correlate positively with the serum reactivity of NP-III-P related antigens (r = 0.692) and with the excretion of urinary pyridinoline (r = 0.455). Thus, both parameters seem to reflect similar mechanisms of connective tissue activation and may be related to inflammatory activity in joint diseases.
