Etretinate therapy in children with severe keratinization defects

Area of Science:

• Dermatology
• Pharmacology

Background:

• Keratinization defects are severe, disfiguring skin conditions.
• Retinoids, like etretinate, offer effective symptomatic oral therapy.

Purpose of the Study:

• To outline the therapeutic potential of etretinate in various keratinization defects.
• To review the toxicology of etretinate, focusing on pediatric treatment.

Main Methods:

• Review of clinical experience with etretinate.
• Analysis of etretinate toxicology data, especially in children.

Main Results:

• Etretinate shows therapeutic potential in lamellar ichthyosis, Netherton syndrome, Sjögren-Larsson syndrome, mal de Meleda, and juvenile pityriasis rubra pilaris.
• No bone changes (e.g., premature growth line closure) or other unacceptable side effects were observed in children.

Conclusions:

• Etretinate is a valuable oral treatment option for severe keratinization disorders.
• Guidelines for safe patient selection and pediatric treatment are provided.
