Background: Hormonal changes, prolonged fasting due to vomiting and some medications used during pregnancy, may cause an acute crisis of porphyria, sometimes unveiling a latent disease. Porphyria may also affect the evolution ...

Background: Acute Hepatic Porphyrias (AHPs) are characterized by an acute neuroabdominal syndrome including both neuropsychiatric symptoms and neurodegenerative changes. Two main hypotheses explain the pathogenesis of ...

AIP is an acute liver disorder caused by a deficiency of porphobilinogen deaminase (PBGD) characterized by neuroabdominal symptoms. It is an autosomal dominant disease. However, homozygous dominant AIP (HD-AIP) have been ...

Porphyrias are a group of metabolic diseases that arise from deficiencies in the heme biosynthetic pathway. A partial deficiency in Hydroxymethylbilane synthase (HMBS) produces the hepatic disorder named Acute Intermittent ...

Hormonal changes, prolonged fasting due to vomiting and some medications used during pregnancy, may cause an acute crisis of porphyria, sometimes unveiling a latent disease. Porphyria may also affect the evolution ...

Porphyria is a metabolic disorder caused by a mutation in the heme biosynthetic pathway, with vague symptomatology and rare prevalence. A triad of hyponatremia, intermittent seizures, and abdominal pain should raise suspicion ...

Porphyrias are a heterogeneous group of metabolic disorders that result from the altered activity of specific enzymes of the hemebiosynthetic pathway and are characterized by accumulation of pathway intermediates. Porphyria ...

Hepatic porphyria is a rare metabolic syndrome caused by abnormal enzyme activity in heme biosynthesis. Between 1974 and 1991; 105 patients have met criteria for diagnosis of hepatic porphyria based on typical clinical ...
