Periodontal Treatment reduces Leptin, CRP and CVD risk in Obese patients: Study

Two hundred sixty patients were screened; 29 patients were included in this study. The study participants comprised 6 patients with Owt/Ob who exhibited SP, 11 patients with Owt/Ob who did not exhibit SP, 5 Nwt patients with SP, and 7 Nwt patients without SP. Periodontal disease status was evaluated; serum levels of leptin, adiponectin, and CRP were determined by enzyme-linked immunosorbent assay at baseline, as well as at 3 and 6 months after NSPT.

The results showed that-

1. At 3 months after NSPT, periodontal status was improved in all groups (p < 0.05), except Nwt patients without SP.
2. Serum levels of leptin and CRP were significantly reduced, while serum levels of adiponectin were elevated after NSPT, regardless of body weight or waist circumference (p < 0.05).
3. Improvement in serum levels of leptin after NSPT was also observed in the Nwt with SP group (p= 0.015); these levels did not significantly differ in Nwt patients without SP.

Hence, the authors concluded that "NSPT reduces serum levels of leptin and CRP and enhances serum levels of adiponectin in Thai patients with Owt/ Ob, irrespective of periodontitis severity. These results suggest a role for periodontal treatment in the systemic inflammatory response of Thai people with Owt/Ob."
