Acute intermittent porphyria (AIP) is a genetic disorder affecting the deaminase gene, leading to porphobilinogen accumulation. Early diagnosis and treatment, including glucose infusions and hem-arginate for neurological symptoms, are crucial for managing this rare condition.

Area of Science:

Biochemistry
Genetics
Internal Medicine

Background:

Acute intermittent porphyria (AIP) is an autosomal dominant genetic disorder.
It results from a partial deficiency of the enzyme porphobilinogen deaminase.
This deficiency impacts heme biosynthesis, leading to toxic porphyrin precursor accumulation.

Observation:

AIP manifests with acute attacks characterized by abdominal pain, neurological dysfunction, and psychiatric symptoms.
Diagnosis relies on detecting elevated urinary levels of delta-aminolevulinic acid and porphobilinogen.
Enzyme activity assays in erythrocytes can be diagnostic between attacks.

Findings:

The case report details a young female patient with a classic presentation of AIP.
Laboratory findings confirmed elevated porphyrin precursors.

Treatment involved glucose infusions and management of hydromineral balance, with hem-arginate for neurological complications.

Implications:

This case underscores the importance of recognizing AIP's diverse clinical manifestations.
Prompt diagnosis and appropriate management are essential to prevent severe neurological damage.
Understanding the genetic basis and metabolic pathway is key for effective therapeutic strategies.
