Hepatitis-Induced Porphyria: Are Direct-Acting Antiviral Agents the Way of the Future?

Porphyria cutanea tarda (PCT) is the most common porphyria and has a strong association with hepatitis C virus (HCV) infection and iron overload. Previous HCV treatment regimens, including interferon with or without ribavirin, may precipitate PCT relapse. Few case reports have shown that newer oral therapies, such as direct-acting antiviral agents, can successfully treat PCT parallel with HCV treatment. We present a case of a patient with non–iron-associated mixed porphyria that dramatically improved with direct-acting antiviral agent therapy for his HCV supporting the association of porphyria with chronic HCV.
