Abstract

Fifty-two patients with sickle-cell (SC) disease (48 with SC-beta-thalassaemia and 4 with homozygous SC-anaemia) were studied as regards blood coagulation and fibrinolysis. It was found that the thrombin and the reptilase times of the patients' plasma were significantly shorter than normal. The mean values of platelet count, fibrinogen level and factor VIII activity of patients with SC disease were higher than normal; however, in the group of patients transfused, with less than 50% haemoglobin S (HbS), the fibrinogen level and the factor VIII activity were significantly lower compared to the other patients. Antithrombin-III (At-III) activity was normal in all. The fibrinolytic activity was normal in patients with asymptomatic SC disease, but reduced in patients on painful crises. Plasminogen and fibrinogen/fibrin degradation product (FDP) levels were normal in all patients. Two patients on painful crises with complications had additional abnormal findings, namely prolonged prothrombin time, reduced At-III level and elevated FDP.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.

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.
