Porphyria Cutanea Tarda Clinical Trial
OBJECTIVES: I. Determine the effect of standard treatments on various predisposing factors
in patients with porphyria cutanea tarda (PCT).
II. Investigate alcohol history, smoking, liver dysfunction and its etiology, estrogen use,
and family history of PCT in these patients.
III. Study the relationships of excess iron and the hemochromatosis gene to PCT, including
clinical features and risk of recurrence in these patients.
IV. Assess hepatitis C virus infections in these patients. V. Assess vitamin C levels in
these patients before and after treatment. VI. Assess dietary habits in these patients. VII.
Assess activity of cytochrome P450 enzymes (CYP) in vivo in these patients.
VIII. Study polymorphic genes for enzymes that metabolize foreign chemicals, including CYP
enzymes and glutathione transferases in these patients.
