Serum immunoreactive prolyl hydroxylase protein and galactosylhydroxylysyl glucosyltransferase activity were measured in 54 patients wtih various dermatological diseases and compared with corresponding values in 32 control subjects. These serum enzymes were at the control level in the great majority of the patients, and no correlation was found between serum and skin enzymes, except for one weak correlation in lichen ruber planus. Some patients with psoriasis, lichen ruber planus, keloids, erythema nodosum or chronic discoid lupus erythematosus, however, did have at least one of these enzymes elevated in the serum, and a significant correlation (P less than 0.01) between the two enzymes was found in the total disease material. Thus it does seem that diseases limited only to the skin can sometimes raise these serum enzyme levels. The mean levels of serum immunoreactive prolyl hydroxylase and galactosylhydroxylysyl glucosyltransferase activity were significantly elevated (P less than 0.001) in active systemic connective tissue diseases such as systemic lupus erythematosus, scleroderma or dermatomyositis compared with the controls, and 4 out of 7 values for immunoreactive prolyl hydroxylase and 3 out of 7 for galactosylhydroxylysyl glucosyltransferase activity were above the 95% confidence limit of the controls. Since the levels of the skin enzymes were not elevated in most of these patients, however, the main sources for the elevated serum enzymes were probably tissues other than the skin.

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.
