Safety and effectiveness tracking for severe eczema treatments

This is a research registry called BIOBADATOP that tracks the safety and effectiveness of systemic treatments for severe atopic eczema (a chronic skin condition). Researchers in Spain will collect information from patients like you who are starting or switching to a new systemic medication — which includes options like cyclosporine, azathioprine, methotrexate, biologic drugs, or phototherapy — to understand how well the treatment works over time and what side effects patients experience.

Severe atopic eczema can seriously affect people's quality of life, and while several systemic treatments exist, doctors need real-world data about which treatments work best for different patients and how safe they are when used in everyday practice. This registry will help doctors make better treatment decisions and create clearer guidelines.
