Haemophilia (British English), or hemophilia (American English) [6] (from Ancient Greek αἷμα (haîma) 'blood' and φιλία (philía) 'love of'), [7] is a mostly inherited genetic disorder that impairs the body's ability to make blood clots, a process needed to stop bleeding.
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 ]
[4] [10] The prolongation of the activated partial thromboplastin time should completely correct with a 1:1 mixing study with normal plasma if haemophilia C is present; in contrast, if a lupus anticoagulant is present as the cause of a prolonged aPTT, the aPTT will not correct with a 1:1 mixing study.

Joint capsule. Haemophilia A's phenotype has a quite wide range of symptoms encompassing both internal and external bleeding episodes. 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.
Haemophilia B, also spelled hemophilia B, is a blood clotting disorder causing easy bruising and bleeding due to an inherited mutation of the gene for factor IX, and resulting in a deficiency of factor IX. It is less common than factor VIII deficiency (haemophilia A). [3]
Naturally acquired disease caused by H. influenzae seems to occur in humans only. In healthy children under the age of 5, H. influenzae type b was responsible for more than 80% of aggressive infections, before the introduction of the [Hib] vaccine. [ 50 ]
By all accounts, the last few years have been brutal for the climate — and for the humans and other living things within it. Around the globe, heat records have been shattered.
Treatment and prevention of bleeding episodes is done primarily by replacing the missing blood clotting factors using "synthetic" or "non-human derived" factor products such as recombinant factor VIII. [24] Factor products work by replacing the missing factor proteins, which can take place at home or in hospital. In the 1970s, haemophiliacs ...
