Abstract
BACKGROUND: Narrow-band UVB is the most innovative steroid sparing treatment in atopic dermatitis. There are studies showing efficacy of Narrow-band UVB in childhood atopic dermatitis, but there is lack of clinical trials in the literature determining the length of remission. Therefore, we sought to highlight its efficacy, safety and its post-treatment efficacy in childhood atopic dermatitis.
OBJECTIVE: To assess the clinical efficacy, safety of Narrow-band UVB in the treatment of paediatric atopic dermatitis and length of remission during 2 years of post-treatment follow-up.
METHODS: Thirty children (4-14 years) having moderate to severe AD (SCORAD index > 25) were enrolled for 12 weeks. Narrow-band UVB phototherapy was administered twice a week on non-consecutive days for three months. SCORAD index was calculated by the same dermatologist at baseline, 6th, 12th, 18th and 24th treatment session. Secondary outcomes were measured using visual analog scale for pruritus and sleep loss. Patients were also followed-up for 2 years to know the length of remission after end of therapy.
RESULTS: There was a significant reduction in SCORAD index at 6th, 12th, 18th and 24th treatment session in comparison to baseline. This improvement in SCORAD was also maintained during the 2 years of post-treatment follow-up period. Consequently, pruritus and sleep loss improved significantly from baseline to end of therapy and even during the 1st and 2nd year of follow-up.
STUDY LIMITATION: Open-label trial without control group.
CONCLUSIONS: Narrow-band UVB is an efficacious and safe modality of treatment in childhood atopic dermatitis with good therapeutic index and minimal side effects.
