The acute hepatic porphyrias [PDF]

Translational Gastroenterology and Hepatology, 2021
The acute hepatic porphyrias (AHP) are a group of four inherited diseases of heme biosynthesis. They present with similar severe, episodic, acute neurovisceral symptoms due to abnormally elevated levels of porphyrin precursors delta-aminolevulinic acid (ALA).

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

Metastases-Like Liver Lesions in Two Different Types of Porphyria - Porphyria Cutanea Tarda (PCT) and Acute Hepatic Porphyria (AHP) - and the Role of CEUS.

, 2023
Porphyria are a group of metabolic disorders caused by altered activity of enzymes in the heme biosynthesis pathway. Acute hepatic porphyria (AHP) are due to hepatic overproduction of the porphyrin precursors, delta aminolevulinic acid, and ...

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

Clinically Important Features of Porphyrin and Heme Metabolism and the Porphyrias

Metabolites, 2014
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.

Urinary porphyrin excretion in hepatitis C infection [PDF]

, 1999
A high prevalence of hepatitis C virus infection in porphyria cutanea tarda in some populations suggests a close link between viral hepatitis and alteration of porphyrin metabolism.

First Report of a Low-Frequency Mosaic Mutation in the Hydroxymethylbilane Synthase Gene Causing Acute Intermittent Porphyria

Life, 2023
Acute porphyrias are a group of monogenetic inborn errors of heme biosynthesis, characterized by acute and potentially life-threatening neurovisceral attacks upon exposure to certain triggering factors.

19-year-old female with abdominal pain [PDF]

Romanian Journal of Neurology, 2013
Porphyria is a group of at least 8 diseases that differ greatly between them. Common feature of these diseases is the accumulation in the body of porphyrins or porphyrin precursors, due to defects of specific enzymes in the biosynthesis of heme.
