Porphyrias: A clinically based approach.
European journal of internal medicine, 2019BACKGROUND Porphyrias are a group of metabolic diseases, individually rare but with an important combined prevalence. Because of their pathological complexity and clinical heterogeneity, they present a challenging diagnosis.

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.

Porphyrias and photosensitivity: pathophysiology for the clinician
Postgraduate medicine, 2018Porphyrias are disorders caused by defects in the biosynthetic pathway of heme. Their manifestations can be divided into three distinct syndromes, each attributable to the accumulation of three distinct classes of molecules.

ALAD porphyria is an autosomal recessive disorder resulting from a homozygous aminolevulinic acid dehydratase (ALAD) deficiency. Because of an almost complete lack of ALAD activity, patients excrete a large amount of ALA, but not PBG, into urine. The symptoms in this disease are similar to those seen in AIP, but ALAD porphyria can be differentiated ...

The porphyrias are a group of metabolic disorders arising from defects in the haem biosynthetic pathway. Most forms are inherited as Mendelian autosomal dominant characters, but some are recessive and others acquired. There is a linked group of diseases, which are not porphyrias, but have in common alterations of haem biosynthesis.

The porphyrias are a diverse group of metabolic diseases. Major manifestations are episodic neurovisceral attacks of pain or other neurologic features, and/or dermatologic abnormalities. It is essential that a clear diagnosis be established prior to planning management.

Disease-a-Month, 1989
The porphyrias are metabolic disorders in which there are excessive accumulation and excretion of porphyrins and porphyrin precursors. Each of the porphyrias has a specific enzyme defect in the pathway of heme biosynthesis that explains the pattern of biochemical abnormalities that occur.

Clinics in Liver Disease, 1998
The porphyrias are metabolic disorders characterized by abnormal heme biosynthesis with excessive accumulation and excretion of porphyrias or porphyrin precursors. Defects in the enzymes of the heme biosynthetic pathway result in porphyria. Several of the disorders have been classified as hepatic because the major site of the biochemical defect has ...
