Acute Hepatic Porphyria. [PDF]
The porphyrias comprise a set of diseases, each representing an individual defect in one of the eight enzymes mediating the pathway of heme synthesis. The diseases are genetically distinct but have in common the overproduction of heme precursors. In the case of the acute (neurologic) porphyrias, the cause of symptoms appears to be overproduction of a ...

Acute porphyrias – A neurological perspective
Acute hepatic porphyrias (AHP) can cause severe neurological symptoms involving the central, autonomic, and peripheral nervous system. Due to their relative rarity and their chameleon‐like presentation, delayed diagnosis and misdiagnosis are common. AHPs

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.

Acute hepatic porphyria - classification, diagnosis and treatment
Porphyrias belong to the group of inherited metabolic diseases. Each of the four types of acute hepatic porphyria is caused by a different mutation in the gene of an enzyme involved in the heme biosynthetic pathway. The literature distinguishes between:

The diagnosis and management of porphyria cutanea tarda (PCT)
The porphyrias are a group of disorders in which excessive quantities of porphyrins or their precursors are produced. They are due to abnormalities in the control of the porphyrin-haem metabolic pathway.

Acute Intermittent Porphyria in a Man with Dual Enzyme Deficiencies
Porphyrias are a heterogeneous group of metabolic disorders that result from the altered activity of specific enzymes of the heme biosynthetic pathway and are characterized by accumulation of pathway intermediates.

Endothelial Dysfunction in Acute Hepatic Porphyrias
Background Acute hepatic porphyrias (AHPs) are a group of rare diseases caused by dysfunctions in the pathway of heme biosynthesis. Although acute neurovisceral attacks are the most dramatic manifestations, patients are at risk of developing long-term complications, several of which are of a vascular nature.

Background: Acute hepatic porphyria includes four inherited disorders caused by partial deficiencies of enzymes related to the heme biosynthesis. Clinical manifestations include acute attacks, occurring mainly among female patients.
