Serum levels of carrier proteins, transferrin, ceruloplasmin and albumin were determined in patients with rheumatic disorders, along with serum levels of acute phase proteins, ceruloplasmin, alpha 1-acid glycoprotein and alpha 1-antitrypsin. Depressed levels of transferrin occurred in rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). Albumin was reduced in SLE and RA men. Acute phase reactants which are protective in inflammation were elevated in RA, osteoarthritis (OA), gout, pseudogout (PsG), and SLE. All of these rheumatic disorders show biochemical changes compatible with systemic inflammatory disease including gout and PsG which are considered local disorders and OA which is considered noninflammatory arthritis.

Pregnancy-associated alpha 2-glycoprotein (alpha 2-PAG) concentrations have been measured in matched sera and synovial fluid samples obtained from 36 patients with rheumatoid arthritis and 10 patients with osteoarthritis. Levels of alpha 2-PAG in serum and synovial fluid were significantly higher in rheumatoid arthritis than in osteoarthritis. Calculation of the synovial fluid/serum ratios for alpha 2-PAG gave results which are explicable only if this protein were being synthesised locally. In a longitudinal study of 15 patients with rheumatoid arthritis, concentrations of alpha 2-PAG did not reflect disease activity, unlike those of the classical acute phase reactants, C-reactive protein and caeruloplasmin.

Copper, caeruloplasmin, transferrin, albumin, and total protein were measured in the serum and synovial fluid of 40 patients with rheumatoid arthritis and 40 patients with osteoarthrosis. A raised synovial fluid copper and caeruloplasmin have been found to be characteristic of rheumatoid effusions. The relation between copper and caeruloplasmin in synovial fluid differs from that in serum. Synovial fluid caeruloplasmin was increased disproportionately in relation to other plasma proteins present in rheumatoid effusions.

Sera and synovial fluid were investigated in 45 patients with rheumatoid Arthritis and 50 patients with osteoarthritis in inflammatory exacerbation (control group). The following tests were performed: IgG, IgM, IgA determinations, complement components C3, C3, C4, C3-proactivator, ceruloplasmin, electrophoresis, LDH and total acid phosphatase. 1. Serum levels of the ceruloplasmin, alpha 1, alpha 2 and gamma fractions of electrophoresis are significantly higher in patients with rheumatoid arthritis than in patients with osteoarthritis. 2. Synovial fluid: a) There is a significantly higher concentration of IgG, IgM, IgA, C3-proactivator and total acid phosphatase in the synovial fluid of patients with rheumatoid arthritis. b) C4 is significantly lower in patients with rheumatoid arthritis. c) Both groups were also compared with the help of a point system. Every patient received a plus point when the following criteria were seen: IgM greater than 150 mg/100 ml, C3 greater than 50 mg/100 ml, ceruloplasmin greater than 35 mg/100 ml, alpha 1 greater than 0.21 g%, alpha 2 greater than 0.44 g%, beta greater than 0.60 g% and gamma fraction on electrophoresis greater than 0.90 g%. Another point was added if the criteria ceruloplasmin greater than 22 mg/100 ml and C4 less than 17 mg/100 ml were simultaneously seen. With the help of this points system 48 out of the 50 osteoarthritis patients (96%) received zero points, one received 1 point and one 2 points, as opposed to the patients with rheumatoid arthritis where 35 out of 45 (78%) received one or more points. d) The differentation is not improved through additional testing of the rheumatic factors.

This study was undertaken 1) to determine whether or not renin is present in synovial fluid in patients with rheumatoid arthritis and osteoarthritis, and, if present, 2) to investigate whether it is synthesized in synovial fluid, or it is only transported from the circulation into the synovial cavity. The active renin concentration (indirect) was measured with angiotensin I radioimmunoassay kits. Inactive renin was converted into active renin with Sepharose-bound trypsin. Both active and inactive forms of renin were found in synovial fluid. They were significantly higher in patients with rheumatoid arthritis (n = 9) than in those with osteoarthritis (n = 16). In plasma, the concentration of inactive renin was significantly higher (P less than 0.001) in the former. Albumin, transferrin, alpha 2-macroglobulin, ceruloplasmin and immunoglobulins G and M were also found in synovial fluid. In each disease, a plot of the log ratio of synovial fluid to the serum concentration against the log molecular weight of each protein gave an approximately straight line curve, suggesting that these proteins are derived from the circulation and are transported into the synovial cavity. In contrast, the ratio of synovial fluid to plasma concentrations of active renin was significantly higher than that predicted on the basis of the above-mentioned interrelationships in both diseases, whereas the ratio of inactive renin was significantly lower. These findings suggest that 1) inactive and active renin are filtered into the synovial fluid from the circulation, and that 2) inactive renin is converted into the active form in the fluid.

C reactive protein (CRP) and immunoglobulin G (IgG) were measured in synovial fluid and serum of 72 patients (29 with rheumatoid arthritis (RA), 17 with osteoarthritis, 11 with crystal synovitis, seven with undifferentiated arthritis, and eight with seronegative arthritis). The synovial fluid:serum (SF:S) ratios were compared with those calculated from the SF:S ratios of transferrin, caeruloplasmin, and alpha 2 macroglobulin, using the binomial test within groups and the Mann-Whitney test between groups. In RA synovial fluid CRP concentrations were lower than expected and IgG concentrations higher than expected. In osteoarthritis CRP concentrations were higher than expected. In seronegative arthritis IgG concentrations were raised. The ratio of CRP:IgG was depressed in RA. These findings are consistent with a role for CRP in the inflammatory process of RA, while the CRP:IgG ratio may be of value in the differential diagnosis of joint disease.

Metal-binding proteins (ceruloplasmin, transferrin, ferritin, and lactoferrin), proteinase inhibitors (alpha 1-antitrypsin, alpha 2-macroglobulin and inter-alpha-trypsin inhibitors), and albumin were assayed in synovial fluid obtained from 20 patients with rheumatoid arthritis (RA) and 15 with osteoarthritis (OA). The levels of proteinase inhibitors and metal-binding proteins, except transferrin, were significantly increased in synovial fluid from RA patients as compared with synovial fluid from OA patients. Metal-binding proteins significantly correlated with rheumatoid factor and immune complexes in synovial fluid from RA patients. Proteinase inhibitor levels also significantly correlated with C-reactive protein, and complement components. These results suggest that the raised level of metal-binding proteins and proteinase inhibitors in synovial fluid from RA patients reflect inflammatory activity, and hence may play an important role in the pathogenesis of inflammatory joint diseases.

Individual proteins (transferrin, ceruloplasmin, alpha 2-macroglobulin, IgG, IgA and IgM) were examined in blood and synovial fluid of 11 patients with Reiter's syndrome. ARA-1981 was used as a diagnostic criteria. The control group included 40 patients with rheumatoid arthritis and 31 with osteoarthrosis of the knee joint. Statistically significant differences between the concentrations of individual proteins in patients with Reiter's syndrome, rheumatoid arthritis and osteoarthritis were only established in synovial fluid for IgM and for IgM index Csf/CS.

Synovial fluids of patients suffering from rheumatoid arthritis and osteoarthritis with effusions of the knees were examined. Different parameters were evaluated out of the synovial fluid (immunglobulins, Complement-1Q,-3,-4, haptoglobins, alpha-1-anti-trypsin, alpha-2-macroglobulin, transferrin, ceruloplasmin, rheumatoid factors, total count of cells, and ragocytes) and out of the plasma (blood sedimentation rate). The proteins were analysed by a nephelometricturbidimetric automatic centrifugal analyser. All parameters have been tested by valuable statistical methods and correlated to each other. The results worked out proved the reliability of the used test kits and apparative systems. Correlations within groups of parameters according to their formations (intra-and/or extraarticular) could not have been worked out in a way as it may be supposed. In contrast some parameters themselves are statistically different comparing rheumatoid arthritis and osteoarthritis. In general the results are on a higher level in the rheumatoid arthritis group. Using all parameters mentioned above the statistical differential diagnostic level is based on about 94%. If only blood sedimentation rate, total cell count and ragocytes are evaluated the level is based on 68%.

Concentrations of three immunoglobulins, albumin, ceruloplasmin, alpha-2 macroglobulin and pregnancy zone protein were estimated by immunoelectrophoresis in paired samples of synovial fluid and serum from 12 dogs with degenerative joint disease (DJD) and six normal dogs. The ratios of synovial fluid to serum concentrations (SF/S) of the four non-immunoglobulins showed an almost inverse linear relationship with their molecular weight in both groups. The SF/S were higher in the DJD synovial fluid than in normal synovial fluid. The difference increased with increasing molecular weight and was highly significant for the largest molecules, reflecting an increased permeability and inflammation in the synovial membrane of DJD joints. The SF/S ratios of the three immunoglobulins studied were compared to the diffusion curves of the four non-immunoglobulins. The SF/S ratios of IgM from dogs with DJD exceeded those calculated from the molecular weights. The present observations support the concept that DJD should be considered an inflammatory disease and suggest that immunologic processes may initiate and/or sustain the inflammation.
