Use of topical therapies for pediatric psoriasis: A systematic review

Abstract

Psoriasis is one of the most common chronic skin diseases, affecting 1%-3% of the general population. It can have a significant negative impact on a patient's quality of life, and in approximately 30% of patients first symptoms can be traced back to childhood. We have performed a comprehensive literature search using the MEDLINE database in order to ascertain the efficacy and adverse reactions of topical treatments in pediatric psoriasis. A total of 13 relevant articles were identified on the following topical agents: corticosteroids, calcineurin inhibitors, vitamin D analogs, and dithranol. Corticosteroids achieved clearance in 72.7% of patients. Calcitriol lead to a 57.2%-100% mean improvement in severity, and calcipotriol to 52%-64%. Combination of calcipotriol and corticosteroids achieved an improvement in mean severity ranging between 32.1% and 80%. Treatment with tacrolimus lead to an >50% improvement. Finally, short contact dithranol lead to a variable response in clearance between different studies, ranging between 3.7% and 81%. No serious adverse reactions were documented, the most common local reaction being irritation. Pediatric psoriasis is a common and challenging condition with no easy and definitive solution. Topical agents are safe, easy to use, readily available and cheap. However, they need to be applied repeatedly, may cause skin irritation, and can be messy. Based on the results presented above, we recommend utilizing all the available topical options before escalating to systemic treatments.
