Simplifying Therapy for Factor XIII DeficiencyDiplomat Specialty Infusion Group supports patients throughout treatment.
Factor XIII deficiency is a rare bleeding disorder. People with the disorder have low levels of a protein called clotting factor XIII. This can make it harder for their blood to clot and their wounds to heal. It can also cause abnormal bleeding.
Many people who have factor XIII deficiency aren’t diagnosed because their symptoms aren’t strong enough. The intensity of symptoms depends on the type of factor XIII deficiency you have.

What are the different types of factor XIII deficiency?
There are two types of factor XIII deficiency: inherited and acquired.
When you have inherited factor XIII deficiency, you have mutations in two genes that control how much factor XIII you produce. Your body produces much less factor XIII than it needs — sometimes less than 5 % of the normal amount. Worldwide, one to three people out of every million have this kind of factor XIII deficiency.
Acquired factor XIII deficiency can be caused by several medical conditions, including:
- Hepatitis or cirrhosis (liver conditions)
- Inflammatory bowel disease
- Severe bacterial infections
- Many types of cancer
- Conditions that cause your immune system to respond abnormally
People who have the acquired type produce 20–70% of the normal level of factor XIII. As a result, symptoms are generally mild. People who produce at least 10% of normal factor XIII levels usually won’t even have bleeding episodes.
What are the symptoms of factor XIII deficiency?
If you have factor XIII deficiency, you might have blood in your urine, wounds that don’t heal well, heavy bleeding from wounds, and blood blisters inside your abdomen. Pregnant women can miscarry if they don’t get treatment.
Men who have factor XIII deficiency can have low sperm counts or sterility. These problems often do not respond to treatment.
About 25% of people who have factor XIII deficiency can hemorrhage (bleed heavily) from their brain and spinal cord after mild head trauma. This is a serious risk for patients, even though the bleeding might stop on its own. Symptoms can include headaches, vomiting, seizures, and problems with speech, vision, and hearing.
How does Diplomat help people with factor XIII deficiency?
Diplomat Specialty Infusion Group helps you with medication and customized clinical support. We dispense both of the medications that are used to treat factor XIII deficiency.
People who have inherited factor XIII deficiency can be treated with Corifact®, a factor XIII concentrate. This medication is infused (injected into a vein), usually every three to four weeks. Some patients with factor XIII deficiency can also be treated with a medication called Tretten®, which is also infused.
The body only needs about 10% of the standard level of factor XIII to function normally, so the doses of either medication can be small. Patients must be careful not to exceed the labeled dose to avoid abnormal clotting and side effects.
In an emergency situation where people are bleeding heavily, they can also receive transfusions of cryoprecipitates (blood plasma).
If you have factor XIII deficiency, be careful using aspirin or other medications that can cause bleeding.
