title: NF-kappaB-dependent cytokines in saliva and serum from patients with oral lichen planus: a study in an ethnic Chinese population.
abstract: To access the potential roles of NF-kappaB-dependent pro-inflammatory cytokines, including tumor necrosis factor-alpha (TNF-alpha), interleukin-6(IL-6), and interleukin-8(IL-8), in oral lichen planus (OLP), and to explore whether salivary detection of these cytokines is a better monitoring tool than serum for OLP, 30 Chinese patients with OLP and 30 age-sex-matched controls were enrolled in this study. Salivary and serum levels of cytokines were screened by enzyme immunoassay, and both salivary and serum levels of these cytokines were significantly increased in OLP patients in comparison with healthy subjects. Positive statistical correlations existed between these cytokines in serum and saliva. With regards to the subtypes of this illness, only salivary IL-8 levels in erosive form were remarkably inclined than that in reticular form. The results suggest that saliva-based test may provide a more cost-effective adjunctive tool for the detection of pro-inflammatory cytokines in OLP, and salivary IL-8 analysis may be a promising biomarker for OLP severity.
