Acute Intermittent Porphyria: Flaccid Quadriplegia and Encephalopathy due to Posterior Reversible Encephalopathy Syndrome (PRES) [PDF]

Liaquat National Journal of Primary Care
A deficiency of the enzyme HMB Hydroxymethylbilane synthase function, also known as porphobilinogen deaminase, leads to the emergence of acute intermittent porphyria (AIP). AIP is an uncommon form of hepatic porphyria inherited in an autosomal dominant

Many pitfalls in diagnosis of acute intermittent porphyria: a case report

BMC Research Notes, 2018
Background Acute intermittent porphyria is a rare autosomal dominant disorder caused by a deficiency of the enzyme, hydroxymethylbilane synthase. Recognition of acute neurovisceral attacks can be difficult due to the nonspecific nature of symptoms.

Acute Intermittent Porphyria, Posterior Reversible Encephalopathy Syndrome and Hypertensive Emergency, A Review of The Literature

Egyptian Journal of Critical Care Medicine, 2020
Acute intermittent porphyria is an autosomal dominant inborn error characterized by decreased activity of porphobilinogen deaminase leading to increased levels of haem precursors, namely aminolevulinic acid and porphobilinogen.

Biochemical and hematological analysis in acute intermittent porphyria (AIP): a case report

Anais da Academia Brasileira de Ciências, 2013
Acute intermittent porphyria is the most common acute porphyria caused by a decrease in hepatic porphobilinogen deaminase activity, resulting in an accumulation of delta-aminolevulinic acid and porphobilinogen.

Evaluation of a commercially available rapid urinary porphobilinogen test [PDF]

, 2011
Background: Demonstration of substantially increased urinary excretion of porphobilinogen is the cornerstone of diagnosing acute porphyria crisis. Because porphobilinogen testing is not implemented on clinical chemistry analysers, respective analyses are

The diagnosis and management of porphyria cutanea tarda (PCT)

South African Family Practice, 2009
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.
