| Abstract: | Glycosylated hemoglobin (glyco Hb) was determined by affinity chromatography and Hb S1 and Hb F by Bio-Rex 70 chromatography in patients with sickle cell anemia, SC disease, S beta+-thalassemia, and S beta 0-thalassemia. SC and S beta-thalassemia patients had normal levels of glyco Hb whereas SS patients had significantly lower levels. Within each group of patients a direct correlation existed between Hb F and glyco Hb or Hb S1 levels. A similar relationship was noticed when glyco Hb and Hb F levels were compared in red cell populations of various densities (ages). Hb F seems to influence glycosylation through its effect on red cell survival. |
