AI Article Synopsis

  • Porphyrias are inherited disorders affecting heme biosynthesis, categorized into three types: neurovisceral, cutaneous, and mixed, based on the deficient enzyme.
  • Many people with porphyria experience vague symptoms, leading to misdiagnosis, but acute types can be life-threatening, highlighting the need for accurate diagnosis and treatment.
  • The text explores the history, causes, symptoms, diagnosis, and treatment of porphyrias, along with a brief overview of the eight different types and their unique characteristics.

Article Abstract

Porphyrias are a group of inherited disorders of heme biosynthesis classified as neurovisceral, cutaneous, or mixed. A deficiency of any of the 8 enzymes in the biosynthetic pathway can lead to a variety of clinical symptoms. Classification depends on the defective enzyme. Porphyrias often are misdiagnosed because patients have vague symptoms. However, acute forms of porphyria can be life-threatening, so it is important to make an accurate diagnosis and initiate proper medical management. We discuss the history, pathogenesis, clinical manifestations, diagnosis, and treatment of porphyrias and then briefly describe the 8 types of porphyrias and their distinguishing features.

Acute intermittent porphyria (AIP) is a rare inherited metabolic disorder caused by decreased activity of the enzyme porphobilinogen deaminase in the heme synthesis pathway. This leads to the accumulation of toxic porphyrin precursors, such as porphobilinogen and δ-aminolevulinic acid. Clinical manifestations typically include episodic bouts of severe neurovisceral pain and autonomic dysfunction.

Article Synopsis
  • * The study reviewed 1582 publications from 1904 to 2023, narrowing it down to 22 studies, primarily case reports from the USA, UK, and France, involving 148 patients with skin symptoms associated with HH.
  • * Key findings highlight diverse skin symptoms such as hyperpigmentation and resistant pruritus linked to iron deposition, while also indicating potential links between HH and skin cancers, underlining the importance of early identification for familial care.

Article Synopsis
  • Acute hepatic porphyrias (AHPs) are rare genetic disorders affecting heme production, causing symptoms like severe abdominal pain and other neurological issues, with varying skin effects.
  • These conditions lead to the buildup of specific porphyrin precursors in the blood, but diagnosing them can be challenging due to inadequate testing methods.
  • Early diagnosis and treatment are crucial because AHPs are manageable, and prompt intervention can prevent serious complications, including liver cancer.
