Summary

The problem of interest is the high rate of recurrent SSTIs in children caused by S. aureus despite the use of systemic antibiotic treatment, due to difficulties in decolonization and the prevalence of antibiotic-resistant strains such as MRSA.

This problem will be studied through a randomized, double-blind, placebo-controlled clinical trial of the use of a 0.12% clorhexidine gluconate (CHG) oral rinse in decolonizing S. aureus in the oropharynx in children 5-17 years old. CHG is an excellent candidate for use in children as its safety has been widely established, and it is readily commercially available. Eligible, consented subjects will be asked to participate in a baseline study visit in which swabs of their oropharynx and nares are obtained, and they are educated on the use of either CHG oral rinse or a placebo oral rinse containing saline. The subjects will be instructed to perform the oral rinse twice daily for seven days. Two follow-up visits will occur at 7 and 28 days post-baseline, where subjects' nares and oropharynx are again swabbed in order to ascertain short- and long-term decolonization of S. aureus. This procedure will serve to 1) determine the efficacy of a CHG oral rinse in decolonization of S. aureus, 2) investigate the safety, tolerability, and compliance of oropharyngeal decolonization among children and their caregivers, and 3) determine the genetic backgrounds of strains of S. aureus associated with continued colonization.

Interventions

DRUG

Chlorhexidine gluconate

Oral rinse of either 0.12% Chlorhexidine Gluconate oral rinse to test the safety/efficacy of 0.12% Chlorhexidine Gluconate oral rinse in decolonizing the oropharynx of children colonized with S. aureus.

DRUG

Saline Placebo

Placebo saline oral rinse to to test the safety/efficacy of 0.12% Chlorhexidine Gluconate oral rinse in decolonizing the oropharynx of children colonized with S. aureus.
