Abstract

Abstract: Background: Immunoglobulin G (IgG) antibodies against periodontal microorganisms can be markers of periodontal infection because their levels rise following infection and remain elevated several years later. Methods: We evaluated the relationship between groups of IgG antibodies against 19 periodontal microorganisms and diabetes‐related mortality over 27 years among participants of the National Health and Nutrition Examination Survey III (1988 to 1992) aged ≥40 years at the time of examination (N = 8, 153). Results: Individuals in the highest versus lowest antibody tertiles were at 86% higher risk of dying due to diabetes‐related causes in the Red‐Green antibody cluster ( T. forsythia, T. denticola, A. actinomycetemcomitans, E. corrodens, S. noxia, V. parvula, C. rectus ) (hazard ratio [HR], 1.86; 95% CI, 1.09 to 3.20) and 55% lower in the Orange‐Blue antibody cluster ( E. nodatum, A. naeslundii ) (HR, 0.45, 95% CI, 0.32 to 0.63) in multivariable models. In these models, individuals with diabetes at the time of examination had a 16‐fold higher risk of dying due to diabetes‐related causes (HR, 16.4; 95% CI, 11.0 to 24.7). Conclusion: As a subset of periodontal microorganisms are associated with adverse systemic outcomes, antibody profiles may help in prediction of diabetes‐related mortality and identify subgroups of individuals among whom periodontal treatment may impact diabetes‐related outcomes.
