Abstract

Sickle cell anemia (SCA) is a genetic disorder characterized by severe hemolytic anemia, frequent vaso-occlusive events and infections. In tropical environment, people are continuously in contact with infection agents. The present study was undertaken to measure 10 protein parameters in order to test humoral immunity, nutrition status and the relation between inflammation and hemolysis in sickle cell anemia patients in 45 Congolese sickle cell children (15 females and 30 males, median age: 7 yrs) and a control group of 43 well healthy congolese group (18 females, 25 males; median age 18 yrs). Mean values for immunoglobulins (IgG, IgM, IgA), nutrition proteins (albumin, transthyretin and transferrin) and inflammatory and hemolysis markers (C3, CRP, A1GP: alpha1-Glycoprotein acid and haptoglobin) were compared between two groups. Hyperstimulation of humoral immunity was observed in the SCA group. Most significative difference was found with IgA (p < 0,001). Intravascular hemolysis was illustrated by a significant decrease of the haptoglobin/A1GP ratio, and was constantly present in SCA patients. We also described a significative decrease (p < 0,001) of haptoglobin/A1GP ratio between SCA patients with inflammatory syndrom when com...Continue Reading

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.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
