Sometimes even a small cut takes a while to stop bleeding, right? Or have you heard that someone in your family has a blood-related disease? Today we are going to talk about a blood disease that is a bit rare, but it is very important to know about. This is called Hemophilia C.
What is Hemophilia C?
Simply put, hemophilia C is a very rare type of hemophilia. Hemophilia is a condition in which your blood does not clot properly, meaning that when you bleed, it stops slowly or never stops. People with hemophilia C have a special blood protein called a clotting factor , called Factor XI , that helps blood clot. This is also called Factor XI Deficiency , and is sometimes called Rosenthal syndrome .
However, the symptoms of hemophilia C are usually milder than those of the other types of hemophilia (A and B). However, people with hemophilia C may bleed more than normal during surgery or dental procedures. Doctors treat this with fresh frozen plasma, which is made from donated blood. This plasma helps the blood clot.
Is hemophilia C a common condition?
No, this is actually a very rare condition . Imagine, in a country like America, about one in every 100,000 men and women develops hemophilia C. If we compare it to other types of hemophilia, hemophilia A affects about 12 in every 100,000 men, and hemophilia B affects about 4 in every 100,000 men. Researchers are still not sure how often hemophilia A or B affects women.
What are the differences between hemophilia A, B, and C?
All three types of hemophilia are inherited blood diseases . That is, a genetic mutation affects the blood clotting process. But there are some small differences between these three types. Let's take a look at what they are:
- Hemophilia A and Hemophilia B occur when a person inherits a mutated gene from one of their biological parents. However, in hemophilia C, the abnormal gene can be inherited from both parents .
- Unlike people with hemophilia A or B, people with hemophilia C do not usually develop bleeding problems that affect the joints or muscles . This is an important difference.
- Typically, the symptoms of people with either hemophilia A or B are determined by the levels of the clotting proteins, or 'clotting factors', in their blood. For example, someone with severe hemophilia A will have very low levels of that factor. But surprisingly, someone with hemophilia C may have very low levels of that factor, but their symptoms may be very mild .
- Hemophilia A and B can occur in people of all races and ethnicities. However, hemophilia C is slightly more common in people of the Ashkenazi Jewish ethnic group . This does not mean that no one else can develop it, but it is more common among them.
- Hemophilia A and B are more common in men than in women, but hemophilia C affects both men and women equally .
What are the symptoms of hemophilia C?
People with hemophilia C may experience persistent, unstoppable bleeding after major surgery, a serious injury, or childbirth. However, they do not experience spontaneous bleeding , which is when blood starts to flow for no apparent reason.
People with hemophilia C often bleed abnormally after dental surgery, tooth extraction, or tonsillectomy.
Other symptoms may include:
- Frequent nosebleeds .
- Bruises on the body from even the smallest thing.
- Blood in the urine .
- Excessive bleeding after circumcision.
- Painful, swollen bruises after surgery.
- For women, menstruation can last for several days, which is abnormally long.
What are the causes of hemophilia C?
Hemophilia C is an inherited blood disorder . It occurs when you lack a blood protein called Factor XI , one of the 13 clotting factors that help to slow or stop bleeding. This is because you don't have the correct F11 gene .
Normally, this F11 gene carries the instructions for making Factor XI. If this gene is mutated, that is, if it becomes abnormal, hemophilia C develops. This abnormal gene may not make enough Factor XI, or it may not make it at all.
Both males and females inherit hemophilia C only if both biological parents pass on the mutated gene to their child . If someone inherits one normal F11 gene and one abnormal gene, that person is a carrier of hemophilia C, but they do not show symptoms.
Now, look at what can happen when parents with this unusual gene have children:
- Children born to parents with this F11 gene mutation have a 25% chance of developing hemophilia C.
- The children born to those parents have a 50% chance of being carriers of the disease, meaning they only carry the gene without the disease.
- The children of those parents have a 25% chance of inheriting the normal F11 gene.
How do doctors diagnose hemophilia C?
Do you know how doctors diagnose hemophilia C? They will first examine you physically . Then they will ask about your symptoms, such as nosebleeds or bleeding after dental work. They will also ask about your family history and whether anyone in your family has hemophilia or other blood disorders . This information is very important in diagnosing the disease.
What are the main tests used to confirm the diagnosis?
Your doctor will use two main tests to confirm your diagnosis:
- Activated partial thromboplastin time test (APTT): This is a test used to diagnose hemophilia. It allows your doctor to know how long it takes for your blood to clot .
- Clotting factor test: This blood test shows the type of hemophilia and how severe it is .
In some cases, your doctor may request a few more tests:
- Complete blood count (CBC): This test measures and studies blood cells.
- Prothrombin time (PT) test: This also checks how quickly your blood clots.
- Fibrinogen test: This blood test measures the amount of a blood protein called fibrinogen, which helps blood clot.
It is important to note that hemophilia C can sometimes be difficult to diagnose. Why? Blood test results, especially clotting factor test results, may not correlate with a patient's symptoms. For example, a clotting factor test may show that your factor level is very low, but you may not have any symptoms. Also, you may have symptoms of hemophilia C even if your factor level is normal. So the doctor will take all of this into consideration and come to a conclusion.
How is hemophilia C treated?
People with hemophilia C may not need treatment until they have surgery or another medical procedure. If that is the case, doctors use a combination of fresh frozen plasma, made from donated blood, and replacement clotting factors, a combination of drugs that stop the breakdown of clotting factors. If women have unusually heavy or prolonged periods, doctors may prescribe birth control pills .
Can hemophilia C be prevented?
No, hemophilia C is a hereditary blood disorder, so it cannot be prevented . However, if you or someone in your family has the condition, genetic counseling can help you understand the risk of passing it on to future generations.
What can someone with hemophilia C expect?
Most people with hemophilia C have mild symptoms . They rarely cause serious medical problems. Most people don't develop symptoms until they are adults, and those symptoms are usually very mild.
However, you may have bleeding problems after surgery or dental treatment. If you have hemophilia C, it is important to ask your doctor about any precautions you should take . For example, informing your doctor before surgery and avoiding certain medications that increase bleeding (such as aspirin).
Finally, some important things you need to remember
Okay, so, there are a few things you need to remember from what we've talked about:
- Hemophilia C is a very rare blood disease .
- Usually, its symptoms are very mild and rarely cause major health problems.
- Many people only show symptoms in adulthood.
- However, you may bleed more than others during surgery or dental treatment , so it is essential to inform your doctor in such cases.
- If you've been diagnosed with hemophilia C, don't panic. Talk to your doctor to make sure you understand what you need to know and what precautions you need to take .
Remember, having a proper understanding of any medical condition is the best step to dealing with it! You are not alone, and medical advice and support are always available to you.
