Enzyme replacement therapy in porphyrias-IV. First successful human clinical trial of δ-aminolevulinate dehydratase-loaded erythrocyte ghosts
1. 1. A patient with chronic lead intoxication was treated with only one course of highly purified human blood aminolaevulinate dehydratase entrapped in autologous erythrocyte ghosts given intravenously. 2. 2. No untoward effects were observed during or after infusion. 3. 3. An immediate increase in...
