No drug treatment is completely free of risk and lack of response, adverse events and poor adherence may affect its effectiveness. Within this context, this project aims to evaluate the importance of monitoring blood levels and salivary drug used in rheumatic autoimmune diseases in the monitoring of adherence to therapy. In addition, this project intends to use the monitoring of drug levels, based on pharmacokinetic studies and pharmacokinetics/pharmacodynamics modeling, to broaden the understanding of the possible cellular, tissue and immunological mechanisms involved in efficacy and adverse effects of these drugs with the prospect of reducing the damage and maintain therapeutic efficacy. The high-performance liquid chromatography (HPLC) coupled to mass spectrometry, which will be used to evaluate hydroxychloroquine, thalidomide, glucocorticoids, is considered the gold standard technology to qualitative and quantitative analysis of drugs in blood and its comparison with the dosage in the saliva is an improvement in simplification of the process. For biological agents the focus will be on the understanding the loss of efficacy and the possible role of anti-TNF antibodies using ELISA capture methodology.This project will be divided into four sections with their respective sub-projects according to the medications that will be studied: hydroxychloroquine, thalidomide, biologic agents and glucocorticoids.
