BACKGROUND: Interleukin (IL)-1 is closely related to the initiation and progression of periodontal disease. IL-1 levels in the gingival crevicular fluid (GCF) of subjects with periodontitis are higher than those in periodontally healthy controls, and the levels of IL-1 correlate with disease severity. However, soluble IL-1 receptor type II (sIL-1RII), which acts as a decoy receptor for IL-1s, has not been investigated in detail in periodontal disease. The purpose of this study was to measure sIL-1RII levels in the GCF of subjects with chronic or aggressive periodontitis; the correlation between the sIL-1RII levels in GCF and clinical parameters also was examined. METHODS: IL-1beta and sIL-1RII were measured in 64 GCF samples collected from 47 subjects with chronic periodontitis (CP) and 17 subjects with aggressive periodontitis (AgP). The clinical characteristics of each site were recorded at the time of GCF sampling. IL-1beta and sIL-1RII were measured by specific non-cross-reactive enzyme-linked immunosorbent assay. RESULTS: The disease severity was comparable in CP and AgP. IL-1beta was detected in 98% of CP GCF samples and 88% of AgP GCF samples. sIL-1RII was detected in 55% of CP GCF samples and 35% of AgP GCF samples. However, the concentrations of IL-beta and sIL-1RII detected in GCF from subjects with CP or AgP were similar. CONCLUSION: sIL-1RII was detected more often in CP GCF than in AgP GCF, and there was no correlation between GCF sIL-1RII concentration and clinical parameters.
