Benefits of systemically administered adjunctive azithromycin in periodontitis patients non-responsive to initial non-surgical periodontal therapy.
The clinical benefit of using azithromycin in non-surgical periodontal therapy in periodontitis patients where initial treatment has not been successful- a randomized controlled trial

Conditions
Summary
Few cases of periodontitis continue to have residual periodontal pockets with bleeding on probing despite well performed non-surgical periodontal therapy. It is unclear if the use of adjunctive systemic antimicrobials can provide clinical benefits in these cases. If the adjunctive systemic antimicrobial has additional anti-inflammatory properties it may help in the modulation of the host response. Azithromycin is one such antimicrobial with additional anti-inflammatory and host-modulating properties. Although the anti-microbial properties of azithromycin have been studied extensively, there are few studies on its host-modulating and anti-inflammatory properties in the treatment of periodontitis. It is hypothesized that adjunctive administration of azithromycin results in a gain in clinical attachment levels, decreased probing depths, decrease in Periodontal Inflammatory Surface Area (PISA) scores, decreased levels of pro-inflammatory cytokines and decrease in the number of pathogenic bacteria in the periodontal pockets among patients non-responsive to initial periodontal therapy.
Eligibility
Inclusion Criteria3
- a) Diagnosis of periodontitis patients non-responsive to initial periodontal therapy will be determined by the presence of at least 4 sites with probing depth equal to or greater than 6 mm on at least two non-adjacent teeth with bleeding on probing at the recall visit after initial periodontal debridement.
- b) patients in the age range of 30 to 75 years
- c) Presence of at least 16 natural teeth.
Exclusion Criteria6
- a) use of antimicrobials within 3 months preceding the start of the study;
- b) history of sensitivity to azithromycin or macrolides
- c) history of cardiac arrhythmias or history of myocardial infarction
- c) current smokers( equal to or greater than 10 cigarettes/day)
- d) Pregnant women
- e) patients with uncontrolled type II diabetes mellitus

Interventions
Systemic administration of azithromycin will be the intervention in the proposed clinical trial the dose administered - 500mg the duration of administration - once daily for 3 days the mode of administration - oral capsules Both the intervention and control groups will be treated with periodontal debridement at Brisbane City Periodontics and Implants, Brisbane, Mount Gravatt and Oral Health Centre, Herston by calibrated periodontists. Test group will receive azithromycin 500 mg capsules along with periodontal debridement on first day (day 1). The remaining two capsules will be taken on the subsequent days (day 2 and 3). Control group will receive identical placebo capsules with periodontal debridement. Text message/phone call reminders will be placed to the study participants to monitor adherence to the intervention.
