Porphyria cutanea tarda: comparison of cases precipitated by alcohol and estrogens.

Abstract

A group of seven patients with porphyria cutanea tarda (PCT) precipitated by excessive alcohol consumption (A) was compared with a group of nine patients with PCT precipitated by estrogen therapy (B). Comparison was based on clinical signs, biochemical and morphologic evidence of liver disease, results of serum iron studies and response to therapy. Group A patients were men of mean age 57 years; group B patients were women of mean age 39 years who had been taking estrogen orally, either for contraception (in combination with progesterone) or as replacement therapy. Clinical signs were essentially the same in the two groups. Some patients in both groups had biochemical and morphologic evidence of liver disease. Group A patients had elevated values for serum iron and total iron-binding capacity, whereas patients in group B had normal or low values. Cessation of estrogen therapy of less than a year's duration brought about a spontaneous clinical and biochemical remission in group B patients. Otherwise, phlebotomy seemed to be the therapy of choice in both groups.

PIP:

"Classic" porphyria cutanea tarda (PCT) is compared with that precipitated by estrogens in a total of 16 patients. The comparison of the 7 patients with PCT precipitated by excessive alcohol consumption (group A) with the 9 patients with PCT precipitated by estrogen therapy (group B) was based on clinical signs, biochemical and morphologic evidence of liver disease, results of serum iron studies and response to therapy. The Group A patients were men of mean age 57 years; the group B patients were women of mean age 39 years who had been taking estrogen orally, either for contraception (in combination with progesterone) or as replacement therapy. For both groups the clinical signs were essentially the same. Some patients in both groups had biochemical and morphologic evidence of liver disease. Group A patients had elevated values for serum iron and total iron binding capacity; group B patients had normal or low values. There was a spontaneous clinical and biochemical remission in group B patients if estrogen therapy of less than 1 year's duration was stopped. Otherwise, phlebotomy appeared to be the therapy of choice in both groups.
