Many people after 50 year of life suffer pains caused by osteoarthritis (OA), which make their life difficult and painful. There is a probable association of OA with the concentration of certain elements in body fluids. Therefore the aim of the study was to relate the level of essential elements in synovial fluids of patients with OA with the treatment using antiarthritic drugs. Thus, flame-atomic absorption spectrometry was used to determine the concentrations of Fe, Zn, Cu, Mn, Na, K, Ca and Mg in 74 samples of synovial fluids taken from 36 patients. Prior to analysis, the samples of synovial fluids were centrifuged and obtained supernatants were digested by microwave technique. It was found that the level of investigated essential elements was differentiated in patients suffering with OA. High correlation between Zn and K, Na and K, as well as Cu and Mn were revealed. Based on cluster analysis, synovial fluids of patients treated with Diprophos, Euflexxa and Synocrom, can be found almost in all clusters. ANOVA has shown that there is a significant difference between Na level in synovial fluids of patients treated with antirheumatic drugs, and those who were not treated. For the patients treated with Euflexxa, similar relations for Ca and K exist. Principal component analysis has shown that essential elements responsible for variability within studied samples, are Ca, Mg, Cu, Mn and Fe. However, there were no statistically significant relations between the studied macro- and microelements, and treatment using specific preparations.
