The management of porphyria cutanea tarda
AbstractPorphyria cutanea tarda (PCT), the commonest of all porphyrias, is usually characterized by blisters and fragility of skin in light-exposed areas. It can be clinically indistinguishable from other disorders including variegate porphyria and the diagnosis can only be made by rigorous biochemical analysis.

Pregnancy and porphyria cutanea tarda
A 31-year-old woman developed typical clinical and laboratory signs of PCT at the end of her second pregnancy coincident with the summer season. She had elevated liver function values without history of alcoholism, hepatitis or chemical liver damage. She had taken oral contraceptive only before her first pregnancy which was normal. Her hormone analytic

Treatment options in acute porphyria, porphyria cutanea tarda, and erythropoietic protoporphyria
The porphyrias are a group of uncommon metabolic diseases caused by enzyme deficiencies within heme biosynthesis that lead to neurotoxic or phototoxic heme precursor accumulation. There are four acute porphyrias characterized by neuropsychiatric symptoms:

Iron overload in porphyria cutanea tarda
BACKGROUND AND OBJECTIVE: Porphyria cutanea tarda (PCT) is a disorder of porphyrin metabolism associated with decreased activity of uroporphyrinogen decarboxylase (URO-D) in the liver. The relevance of iron in the pathogenesis of PCT is well established:

Clinically Important Features of Porphyrin and Heme Metabolism and the Porphyrias
Heme, like chlorophyll, is a primordial molecule and is one of the fundamental pigments of life. Disorders of normal heme synthesis may cause human diseases, including certain anemias (X-linked sideroblastic anemias) and porphyrias.

Lack of association between porphyria cutanea tarda andalpha 1-antitrypsin deficiency
Objective: To determine whether alpha(1)-antitrypsin deficiency is involved in the pathogenesis of chronic liver disease in patients with porphyria cutanea tarda and in their recently described high prevalence of hepatitis C virus infection.
