OBJECTIVE: This study assessed the impact of chronic periodontitis (CP) and CP associated with type 2 diabetes mellitus (DM) and/or smoking on the serum ratios of pro- to anti-inflammatory cytokines. MATERIALS AND METHODS: Subjects were assigned into one of the following groups: control (n = 25, non-diabetic non-smokers with no history of periodontitis), CP (n = 26, non-diabetic non-smokers with CP), DMCP (n = 30, non-smokers with DM and CP), SCP (n = 27, non-diabetic smokers with CP), and SDMCP (n = 22, smokers with type 2 DM and CP). Serum levels of 18 cytokines were measured using multiplex immunoassays. RESULTS: Six ratios of pro-inflammatory to anti-inflammatory cytokines were significantly higher in the CP group than in the control group (p < 0.05). Eleven, seventeen and nine ratios of pro-inflammatory to anti-inflammatory cytokines were significantly higher in the DMCP, SCP and SDMCP groups than in the control group, respectively (p < 0.05). The SCP group presented higher serum ratios of tumor necrosis factor (TNF)-α/interleukin (IL)-4, TNF-α/IL-5, IL-17/IL-13 and IL-6/IL-13 (p < 0.05) than the CP group. Cluster analysis revealed a relevant cluster composed of ten cytokines (IL-17, IL-23, interferon-γ, IL-12, IL-1β, IL-2, IL-21, IL-6, IL-4 and granulocyte-macrophage colony-stimulating factor [GM-CSF]) in the serum of subjects from the DMCP group. CONCLUSIONS: The ratios of pro- to anti-inflammatory cytokines shift to favor a pro-inflammatory status in the serum of patients with CP and even more when CP is associated with one or both risk factors. CLINICAL RELEVANCE: CP and CP associated with hyperglycemia and/or smoking might contribute to a systemic inflammatory burden and increased risk of systemic complications.
