Frequently Asked Questions (FAQ) :
Currently, there is no cure for hemophilia, but it can be managed effectively with regular treatment and preventive care. Gene therapy offers hope for a long-term solution, but it is still under investigation.
Women can be carriers of hemophilia and may have mild symptoms, but it is rare for them to have the severe form of the disease, as they have two X chromosomes, which usually compensates for the defective gene.
If you suspect a bleeding episode, especially in a joint or muscle, you should seek medical attention immediately. Administering clotting factor replacement therapy as soon as possible can prevent further complications.
Patients with hemophilia require special management during surgery, including the administration of clotting factor replacement therapy before, during, and after the procedure to prevent excessive bleeding.
What is Hemophilia ?
Hemophilia is a rare genetic disorder that impairs the blood’s ability to clot properly, leading to excessive bleeding even from minor injuries. This condition is caused by a deficiency in one of the clotting factors, which are proteins in the blood that control bleeding. Hemophilia primarily affects males, as it is usually inherited in an X-linked recessive pattern. There are two main types of hemophilia: Hemophilia A and Hemophilia B, each caused by a deficiency in different clotting factors. Dr. Rahul Bhargava, an expert in hematology, provides specialized care for patients with hemophilia, offering the latest treatments and management strategies.
Causes of Hemophilia
- Genetic Inheritance: Hemophilia is inherited in an X-linked recessive pattern. Since males have one X and one Y chromosome, a single defective gene on the X chromosome will cause the disorder. Females, with two X chromosomes, are typically carriers of the gene and usually do not exhibit symptoms, although they can pass the gene to their offspring.
- Spontaneous Mutations: In some cases, hemophilia can occur due to a spontaneous mutation in the gene responsible for clotting factors, with no family history of the disorder.
Types of Hemophilia
Hemophilia is classified into two main types based on the specific clotting factor that is deficient:
- Hemophilia A: Also known as classic hemophilia, Hemophilia A is caused by a deficiency in clotting factor VIII. It is the most common type, accounting for about 80% of all hemophilia cases.
- Hemophilia B: Also known as Christmas disease, Hemophilia B is caused by a deficiency in clotting factor IX. This type is less common, affecting approximately 20% of individuals with hemophilia.
Symptoms of Hemophilia
- Excessive Bleeding: The hallmark symptom of hemophilia is excessive or prolonged bleeding, particularly after injuries, surgeries, or dental procedures. In severe cases, spontaneous bleeding may occur without any apparent injury.
- Joint Bleeding: Bleeding into the joints, also known as hemarthrosis, is a common and serious complication of hemophilia. It can cause pain, swelling, and over time, lead to joint damage and arthritis.
- Muscle Hemorrhages: Bleeding into muscles can cause pain, swelling, and stiffness. Large muscle bleeds can compress nerves and blood vessels, leading to further complications.
- Bruising: Individuals with hemophilia often bruise easily, even from minor bumps or falls.
Diagnosis of Hemophilia
- Family History: A detailed family history can help identify individuals at risk of hemophilia, especially if there is a known family history of the disorder.
- Blood Tests: Blood tests are used to measure the levels of clotting factors in the blood. A significantly lower than normal level of factor VIII or IX indicates hemophilia A or B, respectively.
- Genetic Testing: Genetic testing can identify specific mutations in the genes responsible for hemophilia. This is particularly useful for prenatal diagnosis or in cases where family history is unclear.
- Prenatal Testing: For families with a known history of hemophilia, prenatal testing can be performed to determine if the fetus has inherited the disorder.
Treatment of Hemophilia
- Replacement Therapy: The mainstay of treatment for hemophilia is replacement therapy, where the missing clotting factor (factor VIII for hemophilia A or factor IX for hemophilia B) is infused into the bloodstream. This can be done on a regular basis (prophylactic treatment) or as needed (on-demand treatment) to prevent or control bleeding episodes.
- Desmopressin (DDAVP): For mild cases of hemophilia A, desmopressin, a synthetic hormone, can be used to stimulate the release of stored factor VIII from the body’s tissues.
- Gene Therapy: Gene therapy is an emerging treatment option that aims to provide a long-term solution by introducing a functional copy of the defective gene into the patient’s cells. This approach is still under research but shows promise in reducing or eliminating the need for regular replacement therapy.
- Management of Complications: Managing complications such as joint damage, pain, and infections is a critical part of hemophilia care. This may involve physical therapy, pain management, and, in some cases, surgery.
- Preventive Care: Patients with hemophilia are advised to take preventive measures, such as avoiding contact sports, using protective gear, and practicing good dental hygiene to prevent bleeding.
