The aim of the present study was to compare concentrations of cytokines, matrix metalloproteinases (MMPs) and a metalloproteinase inhibitor (TIMP-1) in gingival crevicular fluids (GCF) from sites with gingival inflammation in 28 young patients with Papillon-Lefevre syndrome (PLS), and in age- and gender-matched controls. Each group consisted of 17 females and 11 males with a mean age of 11.0 years (range 4-22 years). In both groups, anterior upper sites with a clinical diagnosis of gingival inflammation and with pockets < or = 3 mm were selected for sampling of GCF, which was carried out with filter disks inserted into the gingival crevice until saturated. The concentrations of cytokines (IL-1alpha, IL-1beta, TNF-alpha, and IL-8), matrix metalloproteinases (MMP-1, MMP-3, MMP-8, and MMP-9), and their tissue inhibitor (TIMP-1) were analysed using commercial ELISA kits. Significantly higher levels of IL-1beta (P < 0.001) and MMP-8 (P < 0.05) were disclosed among the PLS patients compared with their controls, while the opposite was found for IL-8 (P < 0.05) and MMP-1 (P < 0.001). The individual variations were considerable in both groups. When comparing the expression of cytokines, MMPs, and TIMP-1 in PLS patients with clinically active and non-active periodontitis, the non-active PLS patients showed significantly higher values of IL-1beta than the patients with active periodontal disease (ANOVA, P < 0.01). In conclusion, this study was unable to demonstrate a clear-cut pathognomonic expression of cytokines or MMPs in patients with PLS, but further studies on cytokine and MMP output are warranted.
