Acute hepatic porphyrias-A guide for hepatologists

Area of Science:

• Biochemistry
• Genetics
• Internal Medicine

Background:

• Acute hepatic porphyrias (AHPs) are rare inherited disorders of heme biosynthesis.
• They manifest with neurovisceral symptoms due to porphyrin precursor accumulation.
• Diagnosis is frequently delayed by inadequate or improper laboratory testing.

Purpose of the Study:

• To review the clinical presentations of the four types of AHPs.
• To elucidate diagnostic approaches and management strategies.
• To highlight potential complications, including hepatocellular carcinoma (HCC).

Main Methods:

• Literature review of AHPs.
• Analysis of diagnostic criteria and laboratory testing.
• Summary of current treatment guidelines and long-term management.

Main Results:

• AHPs present with diverse symptoms, often leading to diagnostic delays.
• Accurate testing and timely intervention are key to successful management.
• Long-standing AHPs can lead to serious complications like HCC.

Conclusions:

• AHPs are treatable with excellent outcomes when diagnosed and managed early.
• A high index of suspicion and appropriate testing are vital.
• Prompt treatment reduces disease burden and prevents irreversible complications.
