Analysis of IL-10 in HIV-1 patients with chronic periodontitis in northern Brazil

ABSTRACT

The objective of this study was to investigate the levels of IL-10 in the gingival crevicular fluid in HIV-1 positive patients with chronic periodontitis and to compare with HIV-1 negative patients with chronic periodontitis, also to correlate clinical periodontal parameters, viral load and count of CD4 + and CD8 + lymphocytes (LTCD4 + and LTCD8 +). Methods: 33 patients were selected and splitted into two groups 16 HIV-1 positive patients and 17 HIV-1 negative patients and all with chronic periodontitis. The clinical periodontal parameters recorded were Probing Depth (PD) and Clinical Attachment Level (CAL); the sistemical parameters LTCD4 +, LTCD8 + and viral load were analized by the gingival crevicular fluid collected from all patients. Enzymelinked immunosorbent assay (ELISA) was used to determine the concentrations of Interleukin (IL)-10. For the statistical analysis the Student t, Mann-Whitney and Spearman tests were performed. IL-10 levels were significantly lower in both patients groups. Results: There was statistical difference betwen groups for probing depth (p=0.015) and clinical attachment level (p=0.011), no significant correlation was found among the analyzed variables. Conclusion: The IL-10 levels in HIV-1 positive patients had no influence in periodontal and medical parameters (AU)
