The objective of this study was to determine the relationships between saliva protein concentrations, oral mucosal lesions, and systemic parameters in HIV positive patients and controls. Twenty-three control volunteers and 58 HIV-antibody positive patients received a complete oral examination and medical evaluation. In saliva and serum samples, protein concentrations were recorded by a nephelometric method. The systemic parameters assessed were CD4+ cell count, CDC stages and antiretroviral therapy. Oral mucosal lesion prevalence was higher among subjects with lower CD4+ counts. Considering the protein profile, correlations were recorded between saliva and serum protein concentration for IgA, haptoglobin and alpha1-proteinase inhibitor. Using assays of immune and non-immune saliva defence factors, we found that the evolution of cellular immuno-suppression during HIV infection was correlated to oral mucosal disease, showing a relationship between local and general systems. |
