The content of IgG, IgA, IgM, transferrin, haptoglobin, alpha2 macroglobulin, alpha1 acid glycoprotein, alpha1 antitrypsin, beta1C/1A globulin and beta1E globulin in the sera of 172 female rheumatoid patients and 132 female non-rheumatoid subjects was measured by the single radial immunodiffusion method. Rheumatoid patients were classified into 3 groups according to their stage and class. Canonical discriminant analysis revealed that the alpha1 acid glycoprotein and beta1C/1A globulin was of assistance in differentiating the rheumatoid and non-rheumatoid groups. There is no significant difference in serum protein levels between rheumatoid factor positive and negative groups, whereas IgA and beta1E globulin levels exhibited certain differences between these two groups. Among the results of other clinical tests, the correlation observed between ESR and serum protein levels in rheumatoid arthritis should be mentioned.

In a series of 100 adult patients with definite rheumatoid arthritis of at most 3 years' duration and with no previous penicillamine, gold or systemic corticosteroid treatment, 50 patients were treated with D-penicillamine and 50 with gold for one yar. The dose of penicillamine was 600 mg daily. Sodium aurothiomalate was given 50 mg weekly up to a total of 13 mg/kg and thereafter 50 mg once a month. In both treatment groups a statistically significant decrease in the number of painful and/or swollen joints, an increase in haemoglobin and a decrease in ESR, serum ceruloplasmin-, alpha1-acid glycoprotein-, IgG-, IgM- and IgA levels was observed. All the changes in these clinical and laboratory tests were of the same degree in both treatment groups. In the penicillamine group 12 out of 20 seropositive patients became seronegative and in another 5 the Waaler-Rose titre dropped clearly. In the gold group, 7 out of 16 seropositive patients became seronegative, and the Waaler-Rose titre dropped in another 5. An equal increase in the number of eroded joints in hands and toes was seen in the penicillamine and the gold group. Penicillamine was discontinued because of side effects in 13 patients (26%), and gold treatment in 15 (30%). Proteinuria and/or haematuria were the most common causes of discontinuation in the penicillamine group.

Serum levels of amyloid protein A (SAA) have been shown to be elevated in different types of amyloidosis and in rheumatic diseases by radioimmunoassay using 125 iodine labeled AA and anti-AA. SAA levels were elevated in both primary and secondary amyloidosis, but there were highly significant differences between these levels. In heredofamilial amyloid, SAA levels were within normal limits. While the mean SAA level was elevated in persons over 70 years, the fact that some persons in this age group had normal levels suggested that marked elevation after age 70 may be due to occult inflammatory or neoplastic disease. High SAA levels in patients with rheumatoid arthritis correlated, in most cases, with physician evaluation of disease activity and Westergren ESR. SAA levels in patients with systemic lupus erythematosus were lower than those in patients with rheumatoid arthritis, and most patients with degenerative joint disease had normal levels. Very high levels of SAA were found in patients with neoplastic diseases. Patients with carcinoma of the lung and bowel had much higher levels than patients with carcinoma of the breast. Determination of SAA levels may be of value in evaluating different forms of systemic amyloidosis, assessing the activity of rheumatic disease, and screening for occult inflammatory or neoplastic disease.

A statistical method was used in the evaluation of alpha-1-antitrypsin, acid alpha-1-glycoprotein, and haptoglobin in patients with rheumatic fever, rheumatoid arthritis, gout, periarthritis, arthrosis with inflammation, and primary arthrosis. A highly significant increase was noted in rheumatic fever and rheumatoid arthritis, less so in arthrosis with inflammation and acute gout, while increases were poorly significant for periarthritis and not significant for primary arthrosis. It can be concluded that the determination of these serum sialoglycoproteins serves to distinguish inflammatory and degenerative rheumatism. Haptoglobin proved the most sensitive of the three. Moreover, there was a distinct correlation between ESR and the three indices. It is felt that sialoglycoproteins act as an indirect pointer to acute inflammation, since their degree of increase is related to the formation of inflammatory proteases.

16 patients with definite and classical rheumatoid arthritis (A.R.A. criteria) were under regular control for 210 days. 11 of them were treated with D-penicillamine and 5 with gold. They were compared to a group of 34 healthy people. In addition to clinical observations the following investigations were carried out at intervals of 20 to 30 days: Latex-fixation test and Waaler-Rose, IgM, IgA, IgG, C3, C4, C3-proactivation, ESR, coeruloplasmin, iron, complete blood picture, gamma-GT, SGOT, SGPT, alk. phosphatase, creatinine, urea and full urinalysis. Furthermore antinuclear factors (ANF) and C-3 activating ANF were determined by indirect immunofluorescence. The following observations were made: 1. The serum level of immuno-globulins changed in a two-phase fashion during D-penicillamine treatment. Initially IgM decreased significantly until the 60th to 80th day. During the 80th to 210th day it tended to increase. Rheumatoid factors changed in a similar way. 2. There was a significant correlation between the IgM serum level and the average titer of the Latex-fixation and Waaler-Rose tests. 3. The other parameters did not change significantly. 4. In one case the ANF became positive and showed a tendency to increase in titre. With higher titres complement activation was demonstrated. The treatment was discontinued. Thereafter the ANF titres and complement binding decreased gradually.

Flurbiprofen and ibuprofen were compared in a six-week double-blind randomized study in 208 patients with rheumatoid arthritis. Daily dosages were 120 mg flurbiprofen and 2400 mg ibuprofen for six weeks. Both drugs were effective in providing partial control of RA symptoms. Either or both drugs produced statistically significant improvement in mean values of time of onset of fatigue, grip strength and tender and swollen joint counts. All other standard endpoints of efficacy (except ESR) were improved but not at a statistically significant level. Slightly more than half of the patients improved during the trial. There was no statistically significant difference in the efficacy of the drugs. The incidence of side effects was low with both drugs. Most side effects were related to gastrointestinal tract irritation.

In a double-blind trial lasting 6 months, 36 patients with classical or definity rheumatoid arthritis were divided into two groups, one receiving 3x300 mg proquazone/day and the other 2x250 mg naproxen plus one placebo capsule/day. Efficacy parameters were assessed and laboratory tests performed at regular intervals throughout the trial. Both drugs were well tolerated, in that no abnormal changes were found in the results of laboratory tests in either group, and that drug-related side effects, mainly gastrointestinal disturbances, occurred in just over half the cases in each group. Both drugs improved the Lansbury Index, especially grip strength, walking time, and ESR. Proquazone did significantly better than naproxen in improving ESR and nocturnal pain. More therpaeutic successes were recorded with proquazone than with naproxen in the overall assessment at the end of the trial.

73 patients with definite active rheumatoid arthritis were treated with naproxen, 250 mg b.i.d. One month after the start of therapy the patients were examined as to following parameters: spontaneous pain and pain on movement, duration of morning stiffness, fatigue, grip strength, functional joint index, ESR and consumption of analgesics. On statistical analysis a significant improvement of all the parameters, with the exception of ESR was shown, 52 of the 73 patients were very satisfied resp. satisfied with the treatment, whereas the physician evaluated the therapeutic results as very good to good in 49 of the cases. In 50 of the patients the therapy with naproxen, 250 mg b.i.d., was continued for two more months. In most of these cases it was possible to achieve an additional improvement in the parameters evaluated. Unwanted side effects occurred in 7 patients, of which in 4 the treatment had to be discontinued (in two cases because of dyspepsia and once each because of an angioneurotic edema and a recurrence of a peptic ulcer, respectively). The three patients in whose cases therapy was continued suffered from mild gastrointestinal disturbances.

Collagen biosynthesis was measured in skin biopsies taken from 13 patients with rheumatoid arthritis before and after at least 6 months' continuous treatment with D-penicillamine, 1.0 g/day. There was a significant 36% reduction in mean collagen biosynthesis (p less than 0.0125) as assayed by 14C-hydroxyproline formation from 14C-proline during 24 h of tissue culture. The changes in 14C-hydroxyproline formation were correlated with the total doses of D-penicillamine taken (r = 0.71, p less than 0.01) and the falls in ESR (r = 0.72, p less than 0.01). No significant change in general protein syntehsis was observed. 500 microgram/mlD-penicillamine added to skil cultures in vitro inhibited both collagen and general protein synthesis (p less than 0.01). It is suggested that the clinical improvement induced by D-penicillamine could reflect an inhibition of collagen proliferation in the synovium.

In order to clearly understand the synovial metabolic pathway of 5-HT, which is interesting as an inflammatory mediator and a pain producing substance, in patients with RA and with OA, determinations were made of 5-HIAA levels and of the activities of MAO-A and MAO-B, in the synovial fluid and the blood. With respect to 5-HIAA levels, there was no significant difference in the synovial levels between patients with RA and those with OA, although higher values were obtained in the plasma of patients with RA. A correlation was found between synovial and plasma levels in both diseases. In patients with RA, 5-HIAA levels tended to increase in both levels of the synovial fluid and the plasma in higher stages. The activities of MAO-A and MAO-B in the synovial fluid were found to be lower in patients with RA than in those with OA. The MAO-B activity in the synovial fluid increased in higher stages and correlated with ESR in patients with RA. In patients with RA the efflux of 5-HIAA from the synovial fluid was reduced. No remarkable changes occurred in the permeability of 5-HIAA. The ability to inactivate 5-HT was lower than in OA. The determination of synovial MAO-B activity is useful in diagnosing the status of the patient with respect to rheumatoid arthritis.
