Forty-four subjects with classic or definite rheumatoid arthritis who were on individualized chrysotherapy were observed for changes in serum protein electrophoresis, immunoglobulins, and circulating lymphocyte counts. By paired variate analysis, significant declines from pretreatment values were recorded for the following--electrophoretic protein fractions: gamma, alpha-1, alpha-2, (P less than 0.05); immunoglobulins: IgM--53% (P less than 0.001), IgG--37% (P less than 0.01), IgA--34% (P less than 0.001). Rheumatoid factor decreased in 29 of 39 subjects, 15 becoming seronegative (P less than 0.001); circulating lymphocytes decreased by 27% (P less than 0.001). The maximal suppressive effect on IgG and IgM was not achieved until the third and fourth years of therapy by sustained weekly administration of gold sodium thiomalate (one year cumulative dosage, mean 2106 mg, range 1065-2,885; greater than or equal to 4 year cumulative dosage, mean 8747 mg, range 5,385-15,160 mg). An immunosuppressive effect is suggested by these results.

Thirty-nine subjects with classical or definite rheumatoid arthritis received weekly intramuscular gold sodium thiomalate (GST) to sustain gold blood levels of more than 320 microgram/dl. Statistical analysis revealed significant declines from pre-treatment values for IgM, IgG, and IaA. Rheumatoid factor titer decreased in 29 of 39 subjects, 15 becoming seronegative. Circulating lymphocytes decreased by 27%. The maximal suppressive effect on IgM was not achieved until the 3rd and 4th years of GST administration. Auranofin (AF) 6 mg/day was administered to 15 patients for an average interval of 45 weeks. In vitro and in vivo suppression of lymphocyte mitogen response with AF was more rapid in onset and significantly greater than with GST. Suppression of dinitrochlorobenzene skin sensitization was observed in AF patients. The clinical response in GST treated subjects correlated with suppression of immunoglobulins, rheumatoid factor titer, and circulating lymphocytes. A significant decline in these variables was not achieved for a corresponding interval with AF treatment. It is suggested that chrysotherapy may be applied more widely to immunologically-mediated disorders and perhaps be used to affect selectively B versus T mediated dysfunction.
