Q and A: about health and research

Hematology March 2021: SWA Personal image    Introduction Acute Intermittent Porphyria (AIP) is a rare, inherited metabolic disorder that affects the body’s ability to produce heme , a vital component of hemoglobin. The disease is caused by a partial deficiency of the enzyme porphobilinogen deaminase (PBGD) , leading to the accumulation of toxic heme precursors— aminolevulinic acid (ALA) and porphobilinogen (PBG) —in the body. These compounds can cause acute neurovisceral attacks , particularly under conditions of physiological stress. AIP does not typically cause petechiae , which are small pinpoint red or purple spots on the skin caused by bleeding under the surface. However, understanding the full clinical picture—including the role of medications like warfarin , treatments like hematin , and the potential influence of viral infections —is essential for managing and preventing complications in patients with AIP. 1. Genetic Cause and Pathophysiology of AIP Gene Involv...
