The successful treatment of prurigo pigmentosa with macrolide antibiotics

Recent studies have demonstrated that macrolide antibiotics have anti-inflammatory as well as antibacterial effects. Therefore, macrolide antibiotics have been successfully used to treat patients with various inflammatory diseases. We evaluated the effect of macrolide antibiotics in 4 patients with prurigo pigmentosa who were treated with either 400 mg of clarithromycin or 300 mg of roxyihromycin daily. Eruption and pruritus disappeared with in a week in all the patients while those symptoms were unresponsive to other drugs. Although the mechanism of this effect remains unclear in patients with prurigo pigmentosa, macrolide antibiotics can be considered as an alternative treatment for prurigo pigmentosa.
