ACTIVITY OF PHOSPHATASES IN THE ORAL LIQUID OF PATIENTS FROM POLLUTED AREAS WHO ARE DIAGNOSED WITH GENERALIZED PERIODONTITIS AND RHEUMATOID ARTHRITIS

The aim: To study the activity of acid and alkaline phosphatases as markers of bone metabolism in patients from bad environmental areas who are diagnosed with rheumatoid arthritis and are affected by generalized periodontitis. Materials and methods: A total of 137 residents from Kalush district of the Ivano-Frankivsk region, Ukraine were enrolled in this investigation. There were 105 patients aged between 18 and 60 years with generalized periodontitis of the I-II degree severity selected for further research. Among them were 70 patients diagnosed with rheumatoid arthritis at the stage of remission. The research comprised the study of oral fluid of the examined individuals in order to assess the bone metabolism based on activity of the acid and alkaline phosphatases. Results: The results of the conducted studies testify an increase of acid phosphatase in subgroups of patients diagnosed with rheumatoid arthritis and affected by generalized chronic periodontitis. On the other hand, the obtained results of alkaline phosphatase activity demonstrated a decrease of this indicator in all subgroups. Conclusions: The results of biochemical studies suggest that there is a significant violation of bone tissue metabolism observed in patients from environmentally unfavorable areas affected by generalized periodontitis and diagnosed with rheumatoid arthritis.
