Treatment of Gram-Negative Folliculitis in Patients with Acne

Therapy In Practice

Abstract

Gram-negative folliculitis may be the result of long-term antibacterial treatment in acne patients. It is caused by bacterial interference and replacement of the Gram-positive flora of the facial skin and the mucous membranes of the nose and infestation with Gram-negative bacteria. These Gram-negative bacteria include Escherischia coli, Pseudomonas aeruginosa, Serratia marescens, Klebsiella and Proteus mirabilis. The occurrence of Gram-negative folliculitis should be considered in acne patients in whom oral treatment with tetracyclines has not resulted in a significant improvement of acne lesions after 3–6 months’ treatment. The occurrence of Gram-negative folliculitis in acne patients is believed to be generally underestimated, since correct sampling and bacteriology is rarely performed by clinicians. Gram-negative folliculitis in acne and rosacea patients is best treated with isotretinoin (0.5–1 mg/kg daily for 4–5 months).
