Periodontitis, Metabolic Syndrome
Conditions
Brief summary
A 6-month, parallel-arm, investigator-masked, randomized clinical trial was conducted in patients with MetS and severe periodontitis. Participants were randomly assigned to an Intensive Periodontal Treatment group (IPT; scaling and root planing and azithromycin capsules 500mg/24h/3days) or to a Minimal Periodontal Treatment group (MPT; professional plaque removal and placebo capsules). Blood and subgingival microbiological samples were collected at baseline, 3 and 6 months after therapy. The primary outcome was between-group difference in C-reactive protein (CRP). Secondary outcomes included HbA1c, lipids, α-1 antitrypsin, fibrinogen levels and subgingival microbiota assessment.
Interventions
Patients received non-surgical periodontal therapy in the form of full-mouth scaling and root planing (SRP), in two sessions, 1 week apart, with the use of an ultrasonic scaler (Minipiezon Electromedical Systems EMS, Nyon, Switzerland) and hand instruments, under local anaesthesia.
Supragingival removal of all deposits (plaque and calculus) with an ultrasonic scaler in two sessions, 1 week apart.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in C-reactive protein | Baseline, 3 months and 6 months | Main outcome variable is the change in concentration of C-reactive protein between baseline and 6 months |
Secondary

| Change in Plaque Index | Baseline, 3 months and 6 months | Examination of plaque index |
| Change in Bleeding on Probing | Baseline, 3 months and 6 months | Examination of bleeding on probing |
| Change in the presence of selected periodontal pathogens | Baseline, 3 months and 6 months | Selected periodontal pathogens: Aggregatibacter actinomycetemcomitans, Tannerella forsythia, P.gingivalis, Prevotella intermedia/nigrescens, Parvimonas micra, Campylobacter rectus and Fusobacterium nucleatum |
| Change in Clinical Attachment Level | Baseline, 3 months and 6 months | Examination of clinical attachment level will be determined with a periodontal probe and expressed in mm |
| Change in the proportions of selected periodontal pathogens | Baseline, 3 months and 6 months | Selected periodontal pathogens: Aggregatibacter actinomycetemcomitans, Tannerella forsythia, P.gingivalis, Prevotella intermedia/nigrescens, Parvimonas micra, Campylobacter rectus and Fusobacterium nucleatum |
| Change in the concentration of Inflammatory mediators (IL-1β, IL-6, IL-8 and TNF-α) in plasma and gingival crevicular fluid | Baseline, 3 months and 6 months | The inflammatory mediators will be determined by Luminex |
| Change in the % of Glycated haemoglobin | Baseline, 3 months and 6 months | Analysis of glycated haemoglobin was determined in the Lab of the University Hospital |
