During porphyria management, which temperature strategy is recommended?

• A. Maintain normothermia
• B. Induce hypothermia
• C. No temperature management
• D. Allow hyperthermia

Answer: (A)

Maintaining normal body temperature is preferred because fever can trigger increased activity of hepatic ALA synthase, driving excess production of porphyrin precursors and worsening neurovisceral symptoms in porphyria. Keeping the patient at normothermia minimizes this trigger, helps prevent metabolic stress, and supports stable hemodynamics during management. Inducing hypothermia is not used here because it carries its own risks (shivering, cardiovascular stress, potential coagulation issues) and does not specifically suppress the porphyrin-synthesis trigger. Allowing hyperthermia would directly amplify porphyrin production and worsen the attack. Treating fever promptly with appropriate measures while avoiding temperature fluctuations is the practical approach.
