An overview of the cutaneous porphyrias [version 1; referees: 2 approved] [PDF]
This is an overview of the cutaneous porphyrias. It is a narrative review based on the published literature and my personal experience; it is not based on a formal systematic search of the literature.

Pathogenesis and clinical features of the acute hepatic porphyrias (AHPs)
The acute hepatic porphyrias include four disorders: acute intermittent porphyria [AIP], hereditary coproporphyria [HCP], variegate porphyria [VP], and the rare porphyria due to severe deficiency of ALA dehydratase [ADP].

Recently, new genes and molecular mechanisms have been identified in patients with porphyrias and sideroblastic anemias (SA). They all modulate either directly or indirectly the δ-aminolevulinic acid synthase (ALAS) activity.

Light-induced depigmentation in planarians models the pathophysiology of acute porphyrias
Porphyrias are disorders of heme metabolism frequently characterized by extreme photosensitivity. This symptom results from accumulation of porphyrins, tetrapyrrole intermediates in heme biosynthesis that generate reactive oxygen species when exposed to ...

Acute intermittent porphyria: A case report [PDF]
Introduction. Acute intermittent porphyria is a rare inherited metabolic disorder caused by a decreased level of porphobilinogen deaminase. Subsequent accumulation of by-products in neural elements causes a classic triad of abdominal pain, neurological ...

AGA Clinical Practice Update on Diagnosis and Management of Acute Hepatic Porphyrias: Expert Review
DESCRIPTION: The acute hepatic porphyrias (AHP) are rare, inborn errors of heme-metabolism and include acute intermittent porphyria, hereditary coproporphyria, variegate porphyria, and porphyria due to severe deficiency of 5-aminolevulinic acid ...

Portuguese Consensus on Acute Porphyrias: Diagnosis, Treatment, Monitoring and Patient Referral
Acute porphyrias are a group of rare genetic metabolic disorders, caused by a defect in one of the enzymes involved in the heme biosynthesis, which results in an abnormally high accumulation of toxic intermediates.
