| Abstract: | 1 Background There are no published studies regarding the role of the plasminogen (PLG) system in familial Mediterranean fever (FMF), FMF‐associated secondary amyloidosis, or chronic periodontitis (CP), although recent limited data have focused on the association between FMF and chronic periodontitis. Therefore, the aim of this study was to evaluate the serum, salivary, and gingival tissue levels of PLG in patients with CP, FMF, and amyloidosis. 2 Methods The study population included 122 patients with FMF (only FMF, and FMF and amyloidosis and 128 individuals who were systemically healthy controls. Blood and salivary samples were obtained from the cases and controls, and clinical periodontal parameters were recorded. Serum and salivary PLG levels were assessed. The gingival tissue samples of the case and control groups were analyzed histopathologically and immunohistochemically for amyloid deposition and PLG. 3 Results The amyloidosis group had significantly more severe clinical periodontal parameters than those of the FMF and systemically healthy groups (P < 0.05). Salivary levels of PLG were significantly higher in the FMF and amyloidosis groups compared with those in the control group (P < 0.001). The FMF with periodontitis and amyloidosis with periodontitis groups had higher salivary PLG levels compared with those in the CP group. Serum and salivary PLG levels were significantly associated with the clinical periodontal parameters in the FMF group. The amyloidosis cases had hyperplasia, severe inflammation, and activation of the gingiva. 4 Conclusion The PLG system could play an important role in inflammatory diseases, such as chronic periodontitis, FMF, and FMF‐associated secondary amyloidosis. |
