Contaminated hemophilia blood products were a serious public health problem in the late 1970s up to 1985. Hemophilia A causes a deficiency in Factor VIII , a protein required for blood clotting. Factor VIII injections are a common treatment to prevent or stop bleeding in people with hemophilia A. [ 1 ]
X chromosome. The factor IX gene is located on the X chromosome (Xq27.1-q27.2). It is an X-linked recessive trait, which explains why males are affected in greater numbers. [9] [10] A change in the F9 gene, which makes blood clotting factor IX (9), causes haemophilia B. [11]

Individuals with more severe haemophilia tend to experience more intense and frequent bleeding, whereas those with mild haemophilia typically exhibit milder symptoms unless subjected to surgical procedures or significant trauma.
Acquired haemophilia A (AHA) is a rare but potentially life-threatening bleeding disorder characterized by autoantibodies directed against coagulation factor VIII.These autoantibodies constitute the most common spontaneous inhibitor to any coagulation factor and may induce spontaneous bleeding in patients with no previous history of a bleeding disorder.
Upon analysis, scientists found that participants who stayed on standard statin treatment for their lifetime increased their quality-adjusted life years by 0.24-0.70, and those on higher-intensity ...
