Abstract
BACKGROUND: The aim of this cross-sectional study is to compare the local and systemic levels of soluble receptor activator of nuclear factor-κB ligand (sRANKL), osteoprotegerin (OPG), a proliferation-inducing ligand (APRIL), B-cell activating factor (BAFF), interleukin (IL)-6, and IL-8 in biofluids of patients with thalassemia major (TM) with or without gingivitis. METHODS: Seventy-seven patients are included in this study (TM, n = 29; systemically healthy, n = 48). Gingival crevicular fluid (GCF), saliva, and serum levels of IL-6, IL-8, sRANKL, OPG, BAFF, and APRIL were determined by enzyme-linked immunosorbent assay. Data were analyzed by appropriate non-parametric or parametric statistical tests. RESULTS: Median GCF, serum, and saliva levels for BAFF (P <0.001) and IL-6 and IL-8 (P <0.005) were higher in TM gingivitis than in systemically healthy gingivitis (P <0.001). GCF, serum, and saliva levels for APRIL, sRANKL, IL-6, and IL-8 were higher in TM than in systemically and periodontally healthy comparison groups (P <0.05). Positive correlations were found between bleeding on probing (BOP), plaque index (PI) scores, and GCF APRIL, serum sRANKL, serum OPG, and sRANKL concentrations in TM groups (P <0.05). Several significant positive correlations were found between BOP, PI scores, and biofluid parameters also in systemically healthy groups. CONCLUSION: TM may have a role in the underlying systemic hematologic condition and potentially affect gingival inflammation via dysregulation of lymphocytes and increased activation of osteoclasts.
