Summary
Background: Erythropoietic protoporphyria (EPP) is characterized by development of painful skin symptoms upon exposure to visible light dye to accumulation of the photoactive substance protoporphyrin IX (PpIX) in the skin.This study aimed to quantify the actual light exposure of patients with EPP during everyday life. The investigators further aimed to establish the associations between symptoms and light exposure, use of protective clothes, and erythrocyte PpIX concentration.
