Summary Samples of blood and joint fluid from 30 patients who had taken buffered acetylsalicylic acid were examined for concentrations of total salicylates (TSA), acetylsalicylate (ASA) and salicylate (SA). The data were arranged in groups according to diagnosis of the joint disease. Analysis of the data did not show significant difference in the kinetics of TSA into blood. In groups the time to first appearance of 0.3 mg/l averaged 6.3 min for TSA; these values averaged 7.7 min for ASA and 10.9 min for SA. Close to maximum concentrations in blood averaged 18.9 mg/l for TSA, 3.3 mg/l for ASA, and 23.3 mg/l for SA. The time for first appearance of 0.3 mg/l of total salicylates in joint fluid ranged from 10 to 34 min with an average of 18.1 min; the values of ASA averaged 19.4 min and those of SA 21.9 min. The maximum concentration in joint fluid averaged 15.7 mg/l for TSA, 2.5 mg/l for ASA, and 14.5 mg/l for SA. Transport of salicylates from blood to joint fluid showed a pattern consistent with the type of joint disease. Support was found for the hypothesis that diffusion was the major factor in the movement of salicylates from blood to joint fluid.
