Abstract

To investigate-whether hemoglobin (Hb) synthesis is affected by different treatment protocols used for end-stage renal disease, we analyzed the electrophoretic pattern of hemoglobin in 136 adult patients with chronic renal failure. Forty-seven patients were not in a dialysis program (ND), 29 individuals were on continuous ambulatory peritoneal dialysis (CAPD), 33 patients were on hemodialysis (HD), and 27 subjects had received a kidney transplant (KT). We found 3.6% hemoglobin C, 1.4% hemoglobin S and 3.6% B-thalassemia minor as reported in other studies of Brazilian patients. In addition, we found increased fetal hemoglobin (Hb F) levels in 7.4% of the patients which contrasts with the reported 0.01% prevalence rate of hereditary persistence of Hb F in Brazil. Seven out of ten patients with elevated Hb F belonged to either the CAPD or the KT group. We postulate that stress erythropoiesis is probably the mechanism responsible for the Hb F increase in these patients. However, properly designed clinical studies are still necessary to clarify these questions.

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.
