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.

Variegate porphyria is an autosomal dominant inherited trait resulting in decreased activity of protoporphyrinogen oxidase. It is characterized clinically by photosensitive skin disease and a propensity to acute neurovisceral crises. The disease is found worldwide but has an exceptionally high frequency in South Africa.

Porphyria and pseudo-porphyria in hemodialyzed patients
International Journal of Biochemistry, 1980Abstract A case of “bullous dermatosis of hemodialysis” which turns out to be a true hereditary PCT, is presented. The particularly serious and fast course of the cutaneous lesions might be due to the extremely high level of plasmatic porphyrins, which neither the residual renal function nor the hemodialysis are able to reduce.

Free porphyrins in varying amounts are found to be widely, although somewhat erratically, distributed throughout the animal kingdom, and indeed in most forms of living organisms. It would indeed have been surprising had it been otherwise since the tetrapyrrole ring system is a key material in the fabric of life.

The porphyrias: pathophysiology
Internal and Emergency Medicine, 2010Porphyrias are a group of inherited and acquired metabolic disorders due to a defect in haem biosynthesis. An enzymatic defect at different steps of haem synthesis leads to tissue accumulation and excessive excretion of porphyrins and/or their toxic precursors.

1. The porphyrias are a group of metabolic disorders arising from defects in the haem biosynthetic pathway. Most forms are inherited as Mendelian autosomal dominants, but some types are recessive and others acquired through exposure to porphyrinogenic drugs and chemicals. There is a linked group of diseases, which are not porphyrias, but have in common
