Management of porphyria cutanea tarda in the setting of chronic renal failure: a case report and review.

Abstract

The treatment of porphyria cutanea tarda (PCT) in patients with chronic renal failure poses a therapeutic challenge. In the absence of renal failure, phlebotomy and oral antimalarials have been the standard of care for PCT. However, in the presence of renal failure, associated chronic anemia often precludes the use of phlebotomy, and oral antimalarials are usually ineffective. We describe a patient with severe symptomatic PCT and chronic renal failure whose disease was successfully managed with a combination of high-dose erythropoietin and small volume phlebotomy. We also review several previously reported approaches to management of PCT in the setting of renal failure, which include small repeated phlebotomy, erythropoietin, deferoxamine, chloroquine, plasma exchange, high-efficiency/high-flux hemodialysis, cholestyramine, charcoal hemoperfusion, and kidney transplantation. An algorithm for the management of these patients is proposed.
