What should be administered as treatment for acute intermittent porphyria?

• A. Increased iron intake
• B. Glyceryl trinitrate
• C. Glucose and hemin
• D. Analgesics only

Answer: (C)

Acute intermittent porphyria (AIP) is a metabolic disorder that leads to a deficiency in the enzyme porphobilinogen deaminase, resulting in an accumulation of porphyrin precursors, particularly aminolevulinic acid (ALA) and porphobilinogen (PBG). This accumulation can cause severe abdominal pain and neurological symptoms. The treatment for AIP focuses on alleviating symptoms and preventing acute attacks. Administering glucose and hemin is effective because glucose helps to suppress the production of porphyrins by providing an alternative energy source, which in turn reduces the synthesis of ALA. Hemin, which is a heme-derived substance, acts as a feed-back inhibitor of heme synthesis, further decreasing the levels of porphyrin precursors. Together, glucose and hemin effectively address the underlying metabolic disturbance in AIP and help to restore normal enzymatic function, leading to a reduction in symptoms and preventing further attacks. This underscores the importance of treating the biochemical basis of the disorder rather than just addressing the pain or symptoms. In contrast, the other options—like increased iron intake, glyceryl trinitrate, or analgesics alone—do not target the root biochemical abnormalities in A
