Porphobilinogen and porphyrin synthesis in reticulocytes from uraemic patients

Abstract

Since no information exists concerning porphyrin metabolism in uraemic patients we have measured the activities of delta-aminolaevulinic acid dehydrase (D-ALA-D) and porphobilinogen desaminase (PBG-D) in reticulocytes from uraemic patients, anaemic patients without uraemia and in healthy subjects. Despite a severe anaemia uraemic patients had the same amount of reticulocytes/mul blood. In uraemic patients D-ALA-D activity was reduced to about 20% compared to healthy subjects, PBG-D in uraemia was decreased to about 70%. It is concluded that porphyrin metabolism is altered in uraemic patients.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
