[A comparative study of serum complement (C3 and C4) in inflammatory joint diseases].
The third and the fourth fraction of the complement (C3 and C4), haptoglobin, fibrinogen, alpha 1-glycoprotein, alpha 2-macroglobulin and transferrin were examined in 692 patients with inflammatory joint disease--rheumatism, rheumatoid arthritis, ankylosing spondylarthritis, psoriatic arthritis, Reiter's syndrome, sacroiliitis [correction of sacroileitis], reactive arthritis, gout, osteoarthrosis and nosologically undefined arthritis in active or nonactive phase and in 60 healthy controls. The complement fractions studied show an increase of various degree and importance in almost all groups of patients in both phases studied. The relations between the complement fractions and the other acute phase indices show significant correlations between them and the other acute phase indices. C3 and to a certain degree C4 could be added to the acute phase reacting indices. Their place in the downgrade scale is as follows: fibrinogen, haptoglobin, alpha 1-glycoprotein, C3, C4, alpha 2-macroglobulin, transferrin.
