Clinically Important Features of Porphyrin and Heme Metabolism and the Porphyrias

open access: yesMetabolites, 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.

Acute hepatic porphyrias for the neurologist: current concepts and perspectives [PDF]

open access: yesArquivos de Neuro-Psiquiatria, 2021
Background: Acute hepatic porphyrias represent an expanding group of complex inherited metabolic disorders due to inborn errors of metabolism involving heme biosynthesis. Objective: We aimed to review the main clinical and therapeutic aspects associated

Iron, Heme Synthesis and Erythropoietic Porphyrias: A Complex Interplay

open access: yesMetabolites, 2021
Erythropoietic porphyrias are caused by enzymatic dysfunctions in the heme biosynthetic pathway, resulting in porphyrins accumulation in red blood cells.

Iron in Porphyrias: Friend or Foe? [PDF]

open access: yesDiagnostics, 2022
Iron is a trace element that is important for many vital processes, including oxygen transport, oxidative metabolism, cellular proliferation, and catalytic reactions. Iron supports these functions mainly as part of the heme molecule. Heme synthesis is an

Kidney Involvement in Acute Hepatic Porphyrias: Pathophysiology and Diagnostic Implications [PDF]

open access: yesDiagnostics, 2021
Porphyrias are a group of rare disorders originating from an enzyme dysfunction in the pathway of heme biosynthesis. Depending on the specific enzyme involved, porphyrias manifest under drastically different clinical pictures.

Clinical Manifestations and Diagnostic Challenges in Acute Porphyrias

open access: yesCase Reports in Hematology, 2013
The porphyrias are a group of disorders characterized by an enzyme deficiency in the heme biosynthetic pathway. These can be classified into either erythropoietic or hepatic forms depending on the site of the major enzyme deficiency.

Mechanisms of Neuronal Damage in Acute Hepatic Porphyrias [PDF]

open access: yesDiagnostics, 2021
Porphyrias are a group of congenital and acquired diseases caused by an enzymatic impairment in the biosynthesis of heme. Depending on the specific enzyme involved, different types of porphyrias (i.e., chronic vs. acute, cutaneous vs.

Acute intermittent porphyria: A case report [PDF]

open access: yesVojnosanitetski Pregled, 2021
Introduction. Acute intermittent porphyria is a rare inherited metabolic disorder caused by a decreased level of porphobilinogen deaminase. Subsequent accumulation of by-products in neural elements causes a classic triad of abdominal pain, neurological ...

Prophylactic heme arginate therapy in acute intermittent hepatic porphyria: A case report [PDF]

open access: yesVojnosanitetski Pregled, 2022
Introduction. Among the acute hepatic porphyrias, a small percentage of patients, predominantly female, present with recurrent cyclic attacks of acute intermittent porphyria that occur more than three times a year and sometimes at intervals of less than ...
