Acute intermittent porphyria associated with hyperthyroidism.

Area of Science:

• Endocrinology
• Gastroenterology
• Genetics

Background:

• Abdominal pain with hyponatraemia necessitates a broad differential diagnosis.
• Acute intermittent porphyria (AIP) is a rare genetic disorder of heme biosynthesis.
• Latent porphyria can be unmasked or exacerbated by various factors, including endocrine disorders.

Observation:

• Hyperthyroidism can precipitate acute porphyria attacks in patients with latent AIP.
• These attacks can manifest with severe abdominal pain and hyponatraemia.
• The severity of AIP attacks may be increased in the presence of hyperthyroidism.

Findings:

• The study highlights the importance of considering AIP in the differential diagnosis of abdominal pain and hyponatraemia.
• Development or worsening of hyperthyroidism in individuals with latent AIP can trigger acute episodes.
• Effective management of hyperthyroidism is crucial for preventing recurrent porphyria crises.

Implications:

• Clinicians should include AIP in the differential diagnosis for patients presenting with abdominal pain and hyponatraemia.
• Screening for latent porphyria may be warranted in patients with unexplained abdominal pain and risk factors for AIP.
• Thyroid function assessment and management are critical in patients with known or suspected porphyria to prevent severe attacks.
