Measurements of interleukin-6 in gingival crevicular fluid from adults with destructive periodontal disease.
This paper describes a study of whether or not the amounts of interleukin-6 (IL-6) in gingival crevicular fluid (GCF) are correlated with periodontal clinical measures. A sensitive ELISA was developed to measure IL-6 in GCF. Two male and 3 female adult subjects with periodontal disease were examined at their first appointments, after 3 months, and after 6 months. Data were obtained on plaque index (PI), bleeding index (BI), probing depth (PD), and on the IL-6 content of GCF samples from 16 sites per subject for a total of 240 measurements. Significant correlations were found between BI and IL-6 (P < 0.005) and between PD and IL-6 (P < 0.05), but not between PI and IL-6. Only 6 out of the 80 sites (in 3 of the 5 subjects) showed PD increases of at least 2 mm. However, for each of these 3 subjects, the amounts of IL-6 in the GCF samples from these sites were markedly higher than the mean amounts of IL-6 in the GCF samples from the remaining sites. These findings suggest that IL-6 may be a useful indicator of periodontal disease, although more extensive longitudinal studies are needed to determine the real clinical value of this GCF component.
