Helper (OKT4)/suppressor (OKT8) ratios in the peripheral blood and synovial fluid of patients with rheumatoid arthritis.

Lymphocyte subsets in the peripheral blood of 10 patients with RA were studied using monoclonal antibodies. The mean percentages of total T, T helper, T suppressor and TAR in the peripheral blood of RA patients were not different from those observed in normal controls. In the synovial fluid the mean percentages of T suppressor cells were present in increased numbers associated with a decreased number of autorosette T cells. We conclude that patients with rheumatoid arthritis present distinct immunoregulatory abnormalities in the synovial fluid not present in the peripheral blood. These changes may be related to the immune abnormalities present and related to the etiology of RA.

The effect of auranofin and sodium aurothiomalate on peripheral blood monocytes.

The effect of oral and parenteral gold preparations on the functional capacity of human peripheral blood monocytes was studied in various in vitro systems. Both agents were capable of inhibiting monocyte chemotaxis, expression of Fc and C3 receptor sites and to a lesser extent the reduction of nitroblue tetrazolium dye. No difference was observed in the effect of oral or parenteral gold on normal and rheumatoid monocytes. The inhibition of monocyte function by gold salts was associated with an increase in intracellular cyclic AMP levels. Our data suggests that the beneficial effect of gold salts in rheumatoid arthritis may result from its action on the functional activities of the monocyte-macrophage system.

SAA amyloid protein levels in amyloid-prone chronic inflammatory disorders. Lack of association with amyloid disease.

Serum amyloid protein A (SAA) levels were evaluated by a sensitive radioimmunoassay technique in leprosy, juvenile rheumatoid arthritis and chronic osteomyelitis. SAA was elevated in all 3 groups of patients. The level in each of the patient groups did not reflect the presence of secondary amyloidosis. Our study suggests that serum SAA protein levels should not be considered a routine diagnostic test in patients with chronic inflammatory diseases prone to the development of amyloid disease.

Interleukin 6: a possible marker of disease activity in adult onset Still's disease.

OBJECTIVE: Adult onset Still's disease (AOSD) is an inflammatory disorder with elevated serum acute phase proteins. Interleukin-6 is a major contributor to the acute phase response. We therefore examined the serum levels of CRP, SAA and interleukin-6 in active and inactive AOSD. RESULTS: Active patients had significantly elevated CRP, SAA, and interleukin-6 values. After steroid treatment a marked reduction was observed in all three parameters. There was a close kinetics on the fluctuations of CRP and SAA, but not on IL-6. CONCLUSION: Acute phase proteins and IL-6 are useful markers of disease activity in AOSD.
