Seven different porphyrias form a group of inherited metabolic disorders, each resulting from a partial deficiency of a specific enzyme in the haem biosynthesis pathway. Clinically, the three most important entities are an acute porphyric attack and acute and chronic skin symptoms.

Hereditary porphyrias are a group of eight metabolic disorders of the haem biosynthesis pathway that are characterised by acute neurovisceral symptoms, skin lesions, or both. Every porphyria is caused by abnormal function of a separate enzymatic step, resulting in a specific accumulation of haem precursors.

The risk for hepatocellular carcinoma (HCC) is increased in acute hepatic porphyrias (AHP). The aim of this study was to explore the clinicopathologic characteristics, outcomes, and frequency of HCC in patients with AHP in the United States.

Hyperhomocysteinemia in patients with acute porphyrias: A potentially dangerous metabolic crossroad?
European journal of internal medicine, 2020BACKGROUND Acute porphyrias (AP) are characterized by heme deficiency and induction of hepatic 5-aminolevulinate synthase (ALAS1). Hyperhomocysteinemia (HHcy) is associated with endothelial damage, neurotoxicity and increased risk for vascular diseases ...

The porphyrias are a heterogeneous group of metabolic disorders caused by genetic defects of the enzymes involved in heme biosynthesis. The diseases are characterized by excessive accumulation and excretion of porphyrin or porphyrin precursors. The disorders have been classified as cutaneous, hepatic, or neuropsychiatric according to the organ system ...

Models for human porphyrias: Have animals in the wild been overlooked?
Bioessays, 2020Humans accumulate porphyrins in the body mostly during the course of porphyrias, diseases caused by defects in the enzymes of the heme biosynthesis pathway and that produce acute attacks, skin lesions and liver cancer.

The porphyrias are a group of disorders involving enzymatic defects in heme synthesis. The porphyrias classically manifest neuro-visceral or photocutaneous symptoms based on which enzyme in the heme metabolic pathway is deficient. Although rare, the porphyrias would most likely be encountered in the emergency department in patients presenting with ...
