Often the best choice for care is at a comprehensive hemophilia treatment center (HTC). An HTC provides patients with the care and education to address all issues related to the disorder. The team consists of physicians (hematologists or blood specialists), nurses, social workers, physical therapists, and other healthcare providers who are specialized in the care of people with bleeding disorders.
How to treat hemophilia?
Treatment of Hemophilia. The best way to treat hemophilia is to replace the missing blood clotting factor so that the blood can clot properly. This is typically done by injecting treatment products, called clotting factor concentrates, into a person’s vein. Clinicians typically prescribe treatment products for episodic care or prophylactic care.
How does hemlibra work?
Hemlibra ® works by replacing the function of factor VIII (8) , rather than replacing the missing clotting factor VIII directly. It can be used to either prevent or reduce the frequency of bleeding episodes in people with hemophilia A. This treatment product can be given by injection under the skin. Patients who use Hemlibra ® for prophylaxis and use clotting factor concentrates to treat breakthrough bleeds, can still develop an inhibitor. Traditional laboratory inhibitor testing methods do not work when testing for inhibitors in patients on Hemlibra ®; as such, a specialized testing method called the chromogenic Bethesda assay is needed.
Why is cryoprecipitate not used?

Why do prophylactics need to be tailored?
But because each patient has different clotting factor levels, prophylactic dosage intervals should be tailored individually, depending on the aim of the treatment, bleeding phenotype, the patient’s daily activities, and cost efficacy.
How to treat hemophilia A?
This is done by infusing (giving medication into a vein) a FVIII product into the affected person. When you infuse, FVIII concentrate, the FVIII is immediately available in the bloodstream, and your body can use it to stop or prevent the bleeding.
When did cloning of FVIII and FIX occur?
In the early 1980s, the cloning of FVIII and FIX and subsequent expression of functional proteins occurred. This was during the “bad blood” era (when many individuals with hemophilia being treated with plasma-derived clotting factor were infected with HIV and/or HCV). This led to the development and commercialization of recombinant clotting factors. These initial products were manufactured using Chinese hamster ovary cells or baby mouse kidney cells. Manufacturers injected these cells with the factor gene so that large amounts of the factor protein could be produced. Since the proteins are extracted from animal cells, they are not at risk for containing human viruses. Some factor concentrate products are stabilized using human albumin, while others are stabilized using sucrose. This was life-changing for many with hemophilia, allowing for prophylactic (or preventive) treatment. Some companies are now using human embryonic kidney (HEK) cells to grow the factor.
What is a broviac catheter?
BROVIAC® catheters and HICKMAN® catheters (often referred to as “broviacs”) are similar to a PICC line. However, A BROVIAC® catheter is placed directly into a central vein and threaded to a position just above the heart. It is tunneled under the skin and brought out away from the site where it enters the vein to theoretically prevent bacteria from gaining access to the central portion of the catheter. BROVIAC® catheters contain a “cuff” that is under the skin. As the skin grows into this “cuff,” the catheter becomes more stable, reducing the chance of it becoming pulled out. Like the PICC line, his device is easy to use and does not require sticks into the person’s skin. The difference is that these catheters can last for a prolonged period of time. The most common long-term complications of this type of central line are infection, movement that takes the catheter out of the proper position, and damage to the catheter.
What is a butterfly needle used for?
Peripheral venous access, where a butterfly needle is inserted directly into a vein and is used to infuse FVIII into the bloodstream, is commonly used by those who infuse at home but do not have a venous access device , such as a port, PICC line, or BROVIAC®. Below are some considerations regarding this type of access:
Can you infuse FVIII into bloodstream?
All FVIII products need to be infused directly into the bloodstream. There are several ways to infuse FVIII, and each has its advantages and disadvantages. These include peripheral infusion (accessing a vein with a butterfly needle), port-a-catheter (also called a port), a peripherally inserted central catheter (PICC) line, or a BROVIAC® or HICKMAN® catheter.
Does hemophilia have an inhibitor?
While anyone with a bleeding disorder can develop an inhibitor to clotting factor, those with hemophilia A develop inhibitors more often than the other bleeding disorders. Inhibitors are antibodies that the immune system develops because it perceives the infused FVIII as a foreign substance that needs to be destroyed. Antibodies are proteins that eat up the FVIII before it has time to stop the bleeding.
What is the standard of care for a patient with severe hemophilia?

How to treat bleeding disorders?
Treatment Options for Bleeding Disorders 1 Standard half-life therapies: Standard half-life therapies are used to treat hemophilia A and B, some types of von Willebrand disease, and some rare factor disorders. Dosing can be anywhere from three times a week to every day, depending on the person. 2 Extended half-life (EHL) therapies: EHL contains a molecule that has been modified in some way to delay the breaking down of factor in the body. This results in higher levels of factor in the body lasting for longer, resulting in less frequent infusions. How long the factor is effective in the body depends on the person. Extended half-life therapies are mostly used to treat hemophilia A and B. 3 Bypassing agents are used to treat bleeds in people with hemophilia with inhibitors. These treatments contain other factors that can stimulate the formation of a clot and stop bleeding.
