Antibiotic resistance: shifting the paradigm in topical acne treatment.

INTRODUCTION: Multiple topical therapies are available for mild to moderate acne vulgaris. The role of antibiotics and their resistance in the treatment of acne was reviewed by an expert panel of dermatologists who practice in Canada. METHODS: Prior to the consensus meeting, the panel members filled out a survey on their current practice using topical treatment for acne. A literature review was carried out using information obtained from PubMed, Cochrane Library, Medline, and EMBASE. During a consensus meeting organized at the Spring Dermatology Update on April 27, 2014 in Toronto, ON, the panel had a blind vote on the issues at hand. RESULTS: The panel reached consensus on: 1) Antibiotics are an integral part of acne treatment not only due to their antibiotic effect but also by their anti-inflammatory action. 2) Oral antibiotics should be used for a short period of time if possible. 3) Topical antibiotics should not be used in monotherapy. 4) Retinoids are effective in reducing antibiotic resistance. 5) A benzoyl peroxide wash is as effective as topical benzoyl peroxide in reducing antibiotic resistance. 6) Therapy needs to be re-evaluated in 6-8 weeks versus 12 weeks. The recommendations given by the panel are to be disseminated to both general practitioners and dermatologists. CONCLUSION: For mild to moderate acne treatment, topical antibiotics in monotherapy are not to be used but may be combined with a retinoid or BPO to safely achieve more successful outcomes.
