Article Description

Objectives: This study estimated plasma levels of interleukin IL-1β, IL-6, tumour necrosis factor-α (TNF-α), interferon-γ (INF-γ) in chronic kidney disease (CKD) patients with a single odontogenic pathology. Material and methods: Forty-nine selected adult CKD patients with single odontogenic pathology based on clinical and X-ray examination: patients after proper root canal treatment, without periapical lesions (n = 12), with pulp necrosis (n = 7), with asymptomatic periapical lesions (n = 22), with periodontal disease (n = 8), and 14 with healthy teeth were enrolled. Patients with coexisting different dental pathologies and the evidence of other infection were excluded. In all patients plasma concentrations of CRP, IL-1β, IL-6, TNF-α, and INF-γ were measured. Results: Patients with periodontitis were characterized by increased concentrations of IL-6 and TNF-α. Those with pulp necrosis had significantly more frequently serum CRP level over 2 mg/L and presented significantly elevated IL-6, but decreased TNF-α concentration than in the subjects with healthy teeth. In patients with periapical lesions and patients after root canal therapy, the concentrations of cytokines did not indicate for the systemic inflammation. Conclusions: Periodontitis and pulp necrosis are important sources of systemic microinflammation in CKD patients. Plasma concentrations of IL-6 and TNF-α appear to be more sensitive markers of odontogenic inflammation in CKD patients than CRP. © 2014 Informa Healthcare USA, Inc.
