Investigation of serum antibody titers for periodontopathic bacteria in diabetic patients

Abstract

：The purpose of this study was to clarify the usefulness of serum antibody titers for periodontopathic bacteria as a screening test for periodontal disease in diabetic patients. The subjects comprised 28 diabetic patients who were hospitalized in the Department of Internal Medicine of Keio University Hospital for various periods between July 2010 and December 2011 (mean age, 56.6±10.7 years；18 men, 10 women；mean illness duration, 8.7±6.3 years). Periodontal parameters, including probing pocket depth, bleeding on probing, and tooth mobility, were recorded, and blood tests including hemoglobin A1c, blood glucose level, C-peptide, hs-CRP and the serum antibody titers for four peridontopathic bacteria (Aggregatibacter-actinomycetemcomitans, Eikenella corrodens, Prevotella intermedia, and Porphyromonas-gingivalis) were examined at the time of the first visit to
