These new guidelines were developed to benefit younger patients with inflammatory skin diseases, and may be helpful given the inexpensive nature and general availability of the drug.
Several consensus-based guidelines for the use of methotrexate (MTX) in pediatric inflammatory skin diseases have been developed, according to new findings, filling an unmet need by providing evidence-based recommendations for effective treatment options.1
These guidelines were developed to address the hesitation clinicians often have when considering off-label methotrexate use in pediatric patients for various inflammatory diseases such as morphea, atopic dermatitis, psoriasis, and alopecia areata.2, 3
The drug is still not approved by the US Food and Drug Administration (FDA), and given this fact and the general lack of robust information on its use, the research was authored by Elaine C. Siegfried, MD, from Saint Louis University's School of Medicine in St. Louis, Missouri.
“The aim of this project was to create evidence-based, consensus-derived, detailed recommendations for long-term management of inflammatory skin diseases in pediatric patients, regardless of physician specialty,” Siegfried and colleagues wrote.
A panel made up of 23 clinicians with expertise in research and treatment development, including medical dermatologists, pediatric dermatologists, pediatric rheumatologists, and representatives from the FDA, the industry, patient advocacy groups, and research alliance, participated in the consensus process.
The investigators in their committee made guidelines which were evidence- and consensus-based in 5 distinct areas: indications and contraindications, dosing levels, interactions with immunizations and medications, adverse effects and their management, and needs in monitoring.
Each topic of interest was assigned to a specific committee, which all performed an extensive search of literature and later drafted preliminary statements based on the evidence and expert opinions reviewed.
A modified Delphi process utilizing an online survey platform was employed by the investigators, with 100% participation from their panel. Consensus was then defined as ≥70% agreement on a Likert scale, and statements achieving consensus in the original survey were accepted, while those without consensus were modified based on comments and used for another survey.
The key consensus statements were the following:
The investigators added that generally, methotrexate offers accessibility, reliability, and the ability to be started or stopped by clinicians and patients as needed without compromising effectiveness during re-exposure.
While long-term safety data was shown to be available for the drug, the research team noted that specific efficacy data in pediatric patients with inflammatory diseases continues to be limited.
“MTX has several decades of real-world use to inform long-term safety, but limited disease-specific efficacy data in pediatric patients,” they wrote. “These guidelines are presented to inform dosing, monitoring, and management of potential side effects of MTX for treatment of pediatric inflammatory skin disease.”
