Background: Narrowband ultraviolet B phototherapy (nbUVB) is a well-established, well-tolerated and efficacious treatment for eczema. There is a distinct lack of literature surrounding the therapeutic use of nbUVB in eczema in children and especially in children with higher skin phototypes (III to VI).
Methods: We undertook a retrospective review of children aged 18 years and under with eczema who had undergone nbUVB in our department between 1 January 2011 and 31 December 2017. Abstracted data included sex, age, skin phototype, severity as graded by a paediatric dermatologist, cumulative dose, response to treatment and subsequent remission.
Results: In total, 60 children had nbUVB. Of those, 56 had more than 10 nbUVB exposures. Complete or near-complete clearance was achieved in 31 children (52%). Of those, 24 (77%) had a skin phototype of III or greater. Clinical remission rates of these patients were 100%, 87%, 57% and 52% at 0, 3, 6 and 12 months, respectively. Seventeen patients (28%) suffered side effects. Most commonly these were mild side effects such as erythema and xerosis.
Conclusion: We have demonstrated that nbUVB is a safe, well-tolerated and efficacious form of treatment for children with atopic eczema. We have shown it to be effective in those with skin phototypes greater than III and shown that they are a group that may derive greater long-term efficacy. In clinical practice, preference for nbUVB as second-line treatment, over oral systemics, should always be considered.
