Cimetidine for erythropoietic protoporphyria
Photodiagnosis and Photodynamic Therapy, 2022 Erythropoietic protoporphyria (EPP) is caused by deficiency of the enzyme converting protoporphyrin IX (PpIX) into heme resulting in accumulation of PpIX; leading to photosensitivity and liver toxicity. Cimetidine might inhibit δ-aminolevulinic acid synthase influencing the heme biosynthesis.

Molecular epidemiology of erythropoietic protoporphyria in the U.K.
British Journal of Dermatology, 2010 Background: Erythropoietic protoporphyria (EPP) is a cutaneous porphyria caused by mutations in the ferrochelatase (FECH) or, less frequently, the delta-aminolaevulinate synthase 2 (ALAS2) gene.

Erythropoietic Protoporphyria and Photohemolysis
JAMA, 1964Erythropoietic protoporphyria is a relatively rare metabolic anomaly occurring in childhood and characterized by various types of cutaneous lesions on light-exposed areas. The lesions are a photosensitive response to an excess of protoporphyrin. Diagnosis can be established by demonstrating a quantitative increase in erythrocyte protoporphyrin levels ...

AbstractPartial deficiency of the last enzyme of haem biosynthesis, ferrochelatase, leads to a distinct syndrome of photosensitivity caused by overproduction of protoporphyrin by erythropoietic tissue. Erythropoietic protoporphyria has an indeterminate pattern of inheritance and may be complicated by fulminating liver disease. The recent development of

Erythropoietic protoporphyria in a boy
Archives of Disease in Childhood, 2014A 9-year-old boy was assessed after experiencing a 2-year history of swelling and burning sensations on the dorsal surface of both hands, his face and his nose. His symptoms developed from the age of 2 years, were always associated with exposure to sun or warm temperature and would last up to …

Erythropoietic protoporphyria.
British Journal of Dermatology, 1976The terminal stages of erythropoietic protoporphyria are recorded. The observations are related to the site of the fundamental lesion and the nature of the biochemical defect. The possibly ominous prognosis in this usually mild condition is emphasized. Apart from congenital porphyria, the porphyrias do not usually confer severe cutaneous lesions. These

Erythropoietic protoporphyria (EPP) is an inherited inborn error of porphyrin metabolism caused by decreased activity of the enzyme ferrochelatase, the terminal enzyme of the haem biosynthetic pathway, which catalyses the insertion of iron into protoporphyrin to form haem.

Pseudoainhum and erythropoietic protoporphyria
British Journal of Dermatology, 1988We report the development of pseudoainhum in a patient with erythropoietic protoporphyria, the first report, to our knowledge, of these two unusual conditions occurring together. An excellent cosmetic and functional result was achieved with a Z plasty.

Abnormal in vitro red cell photohemolysis can be used as a diagnostic aid for erythropoietic protoporphyria. Photohemolysis is regularly present in erythropoietic protoporphyria and is negligible in normal subjects, in patients with polymorphic light eruption, and in lead poisoning.
