OBJECTIVES: Pityriasis rosea (PR) is a common skin disorder in children. Its cause is unknown. A recent publication reported a 73% cure rate in patients with PR after treatment with erythromycin. To duplicate this result using a drug with fewer adverse effects and greater biological half-life, we set out to study the effect of azithromycin on PR. Azithromycin is an azalide antibiotic with a spectrum of antimicrobial activity very similar to that of erythromycin.
DESIGN: We randomly assigned 49 children with PR to receive either azithromycin (12 mg/kg per day, up to a maximum of 500 mg/day) for 5 days or a similar-appearing placebo. Study physicians were blinded to patients' treatment type. Two pediatricians had to agree on the diagnosis of PR before patients could be enrolled. Subjects were seen at follow-up visits 1, 2, and 4 weeks after starting treatment.
OUTCOME MEASURES: We measured the appearance of new lesions and resolution of lesions.
RESULTS: Rates of cure and of partial resolution were similar in the azithromycin and placebo groups.
CONCLUSION: Azithromycin does not cure PR.
