%X Rheumatoid arthritis is a systemic inflammatory disease with still unknown aetiology. The purpose of our study was to comparatively investigate the level of haemoglobin, as well as of the heat shock proteins HSP60 and HSP70 as well as their specific antibodies serum levels in rheumatic patients, in order to evaluate their potential role as an aid in the diagnosis of this chronic pathology. This study was performed on patients with rheumatoid polyarthritis. The haemoglobin plasmatic concentration was assessed by a quantitative determination using the automatic analyzer Beckman Coulter Act5diff, while the thermal shock proteins HSP 60, HSP 70 as well as their respective serum antibodies were determined by Western blot method and ELISA assay, respectively. All the patients involved in this study exhibited low values of haemoglobin, known to be an important marker of haematological disorders. These results maintain the idea that anaemia, heart disease, osteoporosis are the most frequent complication for rheumatoid arthritis. The concept of overexpression of endogenous HSPs is central to hypotheses in which HSPs are implicated in the pathogenesis of autoimmune rheumatic disease. The quantification of HSPs levels in the serum of the rheumatic patients showed that both Hsp60 and Hsp70 levels are higher, especially in those patients who had as a secondary disease, like cardiac insufficiency and obesity. The HSP60 and HSP70 antibodies were also highly expressed in our patients. These lesions could be partially due to the fact that despite the ubiquitous and high homology of heat shock proteins among different species, they also represent important antigenic targets of the cellular and humoral immune response. Besides the low level of haemoglobin, the presence of a high level of heat shock proteins and of their corresponding antibodies may be considered as useful markers which could be correlated with the evolution and the severity of a long chain of pathological processes, including the rheumatic diseases.
