Effect of periodontal treatment on the serum antibody levels to heat shock proteins.

We have shown previously that both humoral and cellular immune responses to heat shock protein 60 (HSP60) are elevated in chronic periodontitis patients compared with non-diseased subjects. The aim of the present study was to determine whether periodontal treatment could influence the level of serum antibodies to human HSP60 and Porphyromonas gingivalis GroEL, a bacterial homologue of human HSP60. Sera were obtained from 21 patients with moderate to advanced chronic periodontitis at the baseline examination and again after completion of treatment. Antibody levels were determined using an enzyme-linked immunosorbent assay. The mean anti-P. gingivalis GroEL antibody levels were down-regulated significantly by periodontal treatment when recombinant P. gingivalis GroEL was used as an antigen, whereas antibody levels to P. gingivalis GroEL-specific peptide were significantly elevated following successful periodontal therapy. The mean level of anti-human HSP60 antibody remained unchanged although individual levels of antibody either increased or decreased after periodontal treatment, suggesting that synthesis of these antibodies might be regulated independently during the course of periodontal infection. Although their regulatory mechanisms in chronic infection are not understood, further study would provide insight not only into the role of these antibodies in the pathogenesis of periodontitis but also into the possible link between periodontitis and systemic diseases such as coronary heart disease.[1]
