Oral charcoal therapy of congenital erythropoietic porphyria
Peter V. Tishler – 1 January 1988 – Günther's disease, or congenital erythropoietic porphyria, is a rare autosomal recessive disorder of heme biosynthesis characteristically associated with diminished uroporphyrinogen III cosynthetase activity. Disfiguring photomutilation starts in childhood. Avoidance of sunlight has been the only sure way to prevent or retard photosensitivity. The treatments that have been tried have had limited success. A partial benefit after splenectomy has been reported, but there is little evidence of specific, long‐term improvement.
