How can we optimize the use of methotrexate to treat pediatric patients with inflammatory skin diseases?

INTRODUCTION

Methotrexate (MTX) is a folic acid antagonist used in clinical practice in oncology and rheumatology, as well as in the treatment of inflammatory skin conditions in children. The low-doses of MTX are commonly used in children for the treatment of many inflammatory and autoimmune conditions, including inflammatory skin diseases, due to its anti-inflammatory and immunomodulatory effects.

AREAS COVERED

This review discusses the possibilities for optimizing the use of methotrexate in the treatment of pediatric patients with inflammatory skin diseases. A thorough search through PubMed and Embase databases was performed to identify relevant literature.

EXPERT OPINION

Clinical observations confirm the high efficacy and safety of low-dose MTX in children with inflammatory skin diseases. Unfortunately, to date there are few studies providing guidelines on the optimal dosage of MTX in children with inflammatory skin diseases; routes of administration; principles of monitoring; and the safety of long-term use of this medication in children. There is still a need for specific recommendations on the safest and most effective dosing and monitoring regimen for children treated with methotrexate for inflammatory skin diseases.
