Abstract

Acquired coagulation factor deficiency is a rare bleeding disorder caused by the inhibitors to coagulation factors. We report a case of an elderly hemodialysis patient who presented with the intermittent hematuria and anemia, associated with the prolonged activated partial thromboplastin time and prothrombin time. Laboratory examination revealed undetectable factor VIII activity, decreased factor V activity, and the presence of inhibitors to these coagulation factors. The patient was diagnosed to have inhibitors to coagulation factors VIII and V simultaneously. In addition, hematuria was found to be caused by the right renal hemorrhage. Renal extravasation was treated by transcatheter arterial embolization. Oral prednisolone successfully eradicated the inhibitors. The present case highlights the importance to consider acquired coagulation factor inhibitors for bleeding symptoms, because they are sometimes life-threatening.

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 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.
