QUALIDADE DE VIDA E SUA CORRELAÇÃO COM PARAMETROS BIOQUIMICOS E IMUNOLÓGICOS NA SALIVA.

Abstract

Our aim was to investigate the correlation between the quality of life indicators, from the WHQOOL inventory-bref, the concentration of salivary IgA, IL-6, IL-10, interferon-gamma (IFN-g), tumor necrosis factor alpha (TNF-α), evaluated by enzyme-linked immunosorbent assay (ELISA) and the concentration of glucose, triglycerides, urea, calcium. It was investigate 47 patients with periodontal disease, from the clinic of Periodontics (CP) and 60 patients, 40 climacteric women and 20 young women) from the clinic of Gynecology (CG). In both studies the population evaluated belonged to the classes D and E, and presented a regular quality of life. The best scores of quality of life among de CO patients were found among young males and at the CG among young women. Pre-existing disease were found in 59% of the patients from CO and in 45% form CG. The patients with periodontal disease presented a normal salivary concentration of IgA, and an increased concentration of IL-10. The largest concentrations of IgA, IL-10 and IL-6 were negatively correlated to the quality of life indicators, and the global quality of life was more influenced by the psychological domain. Among the climateric women it was observed a great elevation of salivary TNF-α and IL-10 concentration and a marked decrease on urea concentration of urea. The physical domain has a greater influence than the physical domain on the general quality of life. The largest concentrations of TNF-α and IFN-α, IgA and IL-10 showed a negative correlation with the different domains of quality of life. In addition, we detected positive correlation between the IL-10 and IL-6 and the concentration of glucose and triglycerides. In young women the physical domain has more influence on the quality of life. We conclude that quantification of salivary IL-10 can be useful to evaluate and monitoring the quality of life of patients with periodontal disease and the climacteric women, since it can be associated to either the acute stress that affects patients in waiting rooms of clinics or the chronic stress of women in menopause, as well as interfere in the production of IgA in saliva. Together our data show the importance of the evaluation of cytokines in the saliva as an additional parameter mainly because it is always important the holistic assessment of the patients.
