Are gingival crevicular fluid levels of interferon-γ , but not interleukin-4 or -33 or thymic stromal lymphopoietin , increased in inflamed sites in patients with periodontal disease?
These results suggest that IFN-γ levels in GCF depend on the clinical stage of the site and not on the disease stage of the patient, but need to be expanded to a greater number of subjects and additional analysis of corresponding gingival tissue biopsies for cytokine gene expression.
A significant correlation was found between visceral adipose tissue amount and disease activity in patients with AS.
