Effect of hepatobiliary disease, chronic hepatitis C and hepatitis B virus infections and interferon‐<b>α</b> on porphyrin profiles in plasma, urine and faeces

Abstract

Reduced biliary excretion of coproporphyrin I occurs in more severe cholestasis and/or hepatic dysfunction. A causal relationship between viral liver disease and porphyria cutanea tarda which is unlikely to be precipitated by interferon-alpha, is not supported.
