Citriodiol® and Impetigo

June 18, 2012 updated by: Shreya Dixit, Royal North Shore Hospital

A Randomised, Double-blinded, Pilot Study Investigating the Safety and Efficacy of Topical P-menthane-3,8-diol Oil Extract in the Treatment of Childhood Impetigo.

This study aims to investigate the efficacy and safety of topical p-menthane-3,8-diol (PMD)-rich Corymbia Citriodora oil (Citriodiol®) in children with impetigo. Citriodiol® is already known to be effective as an insect repellent and is safe in its topical application. The investigators have also found in our laboratory that it is bactericidal against Staphylococcus aureus, the bacteria responsible for causing impetigo. Parents are always searching for a natural alternative to antibiotics (the current gold standard treatment for impetigo), and the investigators believe Citriodiol® could provide this possible alternative.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The extract of lemon eucalyptus, a common plant, has since the 1970s been used in commercial insect repellent products. Recently, it has been shown that lemon eucalyptus has potent anti-bacterial and anti-fungal effects that should assist in the treatment of inflammatory conditions such as impetigo. Our aim is to investigate this further by investigating the safety and efficacy of this product in the treatment of Impetigo.

A randomised, double-blinded, three-armed pilot study, involving a total of 30 patients will be recruited from the dermatology outpatient department clinic at Royal North Shore hospital for this study. These patients will be between the ages of 12 months and 12 years with a clinical diagnosis of Impetigo.

The three treatment groups will include a 2% or 5% topical p-menthane-3,8-diol (extracted from lemon eucalyptus) and a topical Mupirocin arm, which will be applied topically twice a day till resolution of symptoms. Follow-up will occur weekly until resolution of symptoms, which is expected within 2 weeks. Photographs, disease severity assessment and lesional swabs for culture will be taken at recruitment and as progress.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

1 year to 12 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study
