Patients were randomly allocated into either one of the arms of the trial. A 1:1 assignment was adopted; however, one patient who was reallocated from the NB-UVB arm to the azithromycin arm due to personal circumstances that would affect his compliance. Accordingly, the azithromycin arm contained 13 patients and the NB-UVB arm contained 11 patients.The dose of azithromycin was 10 mg/kg/day oral suspension for 3 consecutive days for pediatric patients (< 12 years) and 500 mg/day for 3 consecutive days for adults. The cycle was repeated every 10 days for 3 cycles (3 cycles/month) and was repeated when required according to patient’s response up to 6 cycles (Youssef and Elmasry, unpublished data).Patients allocated for NB-UVB phototherapy received sessions according to the protocol of the Phototherapy Unit, Dermatology Department, Cairo University, where an initial dose was dependent on the minimal erythema. The dosage was then increased according to the patient’s response. The sessions were given 3 times weekly.No concomitant therapy was allowed except for Vaseline topical daily application (if needed).
