Insights

Methotrexate (MTX) is effective for pediatric severe plaque psoriasis, showing significant PASI score improvements and PGA 0/1 in most patients. Close monitoring is essential due to potential side effects like elevated liver enzymes and infections.

Area of Science:

  • Pediatric Dermatology
  • Immunosuppressive Therapy
  • Psoriasis Treatment

Background:

  • Limited scientific evidence exists for methotrexate (MTX) use in pediatric severe plaque psoriasis.
  • This study addresses the scarcity of data regarding MTX efficacy and safety in this population.

Purpose of the Study:

  • To retrospectively evaluate the efficacy and safety of oral MTX in children with severe plaque psoriasis.
  • Conducted in a single center in China.

Main Methods:

  • Retrospective analysis of 42 children with severe plaque psoriasis treated with oral MTX.
  • Efficacy assessed using Psoriasis Area and Severity Index (PASI), Physician Global Assessment (PGA), and Body Surface Area (BSA) scores.
  • Safety and quality of life (CDLQI) were also monitored.

Main Results:

  • Significant improvements in PASI, PGA, and BSA scores were observed by week 12.
  • 80.6% achieved PASI75, 47.2% achieved PASI90, and 72.2% achieved PGA 0/1.
  • Common side effects included elevated liver enzymes (28.6%) and infections (28.6%); relapse occurred in 30%.

Conclusions:

  • Oral methotrexate is an effective and safe treatment option for children with severe plaque psoriasis.
  • Adequate patient monitoring is crucial for managing potential adverse events.
  • MTX demonstrated sustained efficacy and improved quality of life in pediatric patients.
