🧬 What is Hemophilia? Types, Symptoms, Treatment & Prevention
Definition: Hemophilia is a genetic bleeding disorder caused by a deficiency in clotting factors—VIII (Hemophilia A) or IX (Hemophilia B)—leading to poor blood clot formation.
📊 Epidemiology & Statistics
- Globally, ~1.12 million men live with hemophilia; ~418,000 have severe forms 0.
- In the U.S., around 33,000 males are estimated to have hemophilia; 80–85% of those have Hemophilia A 1.
- Hemophilia affects about 1 in 5,600 male births for A and 1 in 19,000 for B 2.
🔍 Types of Hemophilia
- Hemophilia A (Factor VIII deficiency) – ~80% of cases.
- Hemophilia B (Factor IX deficiency) – ~15% of cases, known as “Christmas disease” 3.
- Acquired hemophilia – rare autoimmune form; adults develop antibodies to clotting factors.
⚠️ Signs & Symptoms
- Frequent, spontaneous bleeding—often into joints (hemarthrosis), muscles, or soft tissue.
- Prolonged bleeding after minor cuts, surgery, or dental work.
- Easy bruising, nosebleeds, blood in urine/stool.
- Severe cases may show bleeding in the brain or deep tissues.
🧬 Causes & Genetic Inheritance
Hemophilia is X-linked recessive. Males with the faulty gene (on X chromosome) develop the disease; females usually carriers, rarely symptomatic 4.
🧪 Diagnosis & Severity Levels
- Lab tests: Clotting factor assays determine whether Factor VIII/IX activity is mild (> 5%), moderate (1–5%), or severe (< 1%).
- Genetic testing: Detects mutations in the F8 or F9 gene.
💊 Treatment Options
- Factor replacement therapy: Intravenous infusions of recombinant or plasma-derived Factor VIII or IX on-demand or prophylaxis basis.
- Bypassing agents: Used in patients who develop inhibitors against replacement factors.
- Emicizumab & newer Biologics: Long-acting biotherapies offering less-frequent dosing.
- Gene therapy: FDA-approved treatments like Hemgenix for Hemophilia B are paving the way 5.
🛡️ Prevention & Management
- Early prophylactic treatment prevents joint damage and improves quality of life.
- Educate patients and families about safe activities & injury prevention.
- Regular dental care with prior factor infusion to avoid excessive bleeding.
- Genetic counseling advises carriers and helps guide family planning.
🔬 Research & Ongoing Studies
- Clinical trials are underway exploring gene therapy and novel factor concentrates.
- New subcutaneous agents (e.g., Emicizumab) offer effective and patient-friendly administration 6.
- Global registry initiatives (WFH surveys) improving understanding of hemophilia incidence and treatment access 7.
