thrombophilia is a pathological state of increased blood coagulability. it causes problems during pregnancy including preeclampsia, stillbirth, repeated abortions, and detached pair. out of the most prevalent factors causing inherited thrombophilia, protein s (prs), protein c (prc), and antithrombin iii (atiii) deficiency, and factor v leiden (fvl) mutation could be mentioned. this study aimed ...

Acquired haemophilia (AH) is a severe bleeding diathesis that affects both males and females. It is caused by suddenly appearing autoantibodies that interfere with coagulation factor VIII (FVIII) activity. Although some conditions such as autoimmune diseases, cancer and puerperium seem likely to induce AH, in more than half of the observed cases autoantibodies to FVIII are idiopathic. The clini...

The parallel measurement of serum antibodies to the hepatitis G virus (anti-HGV) and of viremia (HGV-RNA) should improve our understanding of HGV transmission by coagulation factor concentrates. The aim of this study was to assess the relationship between HGV, the type of concentrate infused, and liver disease in multitransfused hemophiliacs. To this end, anti-HGV and HGV-RNA were evaluated by ...

In vivo fragmentation of the von Willebrand factor antigen (vWF:Ag) molecule has been demonstrated on radiocrossed immunoelectrophoresis (CIE) in the plasma from patients with disseminated intravascular coagulation, in factor VIII concentrates, and in normal serum. Experiments reported here show that polymorphonuclear (PMN) cells contain a non-calcium-dependent protease(s) that when released an...

Hemophilia is a hematological disorder characterized by a partial or complete deficiency of clotting factor VIII or IX. Its bleeding complications primarily affect the musculoskeletal system. Hemarthrosis is a major hemophilia-related complication, responsible for a particularly debilitating chronic arthropathy, in the long term. In addition to clotting factor concentrates, usually prescribed b...

Prophylactic platelet concentrates transfusion represents a therapeutic choice in patients with chemotherapy-induced thrombocytopenia. This prospective, non-interventional study evaluated the effects of platelet concentrates transfusion on thromboelastometric parameters of platelet function in 36 transfusion occasions for 11 thrombocytopenic children undergoing chemotherapy. Pre- and posttransf...

BACKGROUND Factor VII concentrates are used in patients with congenital or acquired factor VII deficiency or treatment of hemophilia patients with inhibitors. In this research, immunoaffinity chromatography was used to purify factor VII from prothrombin complex (Prothrombin- Proconvertin-Stuart Factor-Antihemophilic Factor B or PPSB) which contains coagulation factors II, VII, IX and X. The aim...
