The influence of cigarette smoking on blood gold distribution during chrysotherapy.

Abstract

Plasma and erythrocyte gold concentrations were measured in 35 patients taking gold sodium thiomalate (GSTM) for rheumatoid arthritis. In 6 patients with adverse effects attributable to gold therapy at the time of sampling, gold concentrations in plasma and erythrocyte fractions were no different from those without adverse effects. A significant difference was seen in the distribution of gold in the blood of cigarette smokers compared to non-smokers, with smokers having higher erythrocyte and lower plasma gold concentrations. A prospective study on 15 patients commencing treatment with GSTM showed that the higher concentrations of erythrocyte gold seen in smokers were achieved within the first 2 weeks of treatment.
