Description
Glanzmann's Thrombasthenia: A Rare Bleeding Disorder
Glanzmann's thrombasthenia (GT) is a rare and inherited bleeding disorder that affects the platelets in the blood. It is characterized by impaired function of platelets, which are essential for proper blood clotting.
Key Features:
- Impaired Platelet Function: GT is caused by defects or deficiencies in the alpha IIb beta3 integrin, also known as glycoprotein IIb/IIIa (GPIIb/IIIa), on the surface of platelets. This impairs the ability of platelets to aggregate and form a blood clot.
- Lifelong Condition: GT is a lifelong condition that requires ongoing management and monitoring by a hematologist.
- Bleeding Episodes: Patients with GT experience frequent bleeding episodes, often involving mucocutaneous membranes such as the nose, gums, and skin.
- Genetic Inheritance: GT is inherited in an autosomal recessive pattern, meaning that both parents must be carriers of the defective gene for their child to inherit the condition.
Symptoms:
- Frequent bruising
- Nosebleeds (epistaxis)
- Bleeding from the gums
- Red or purple spots on the skin caused by bleeding
Causes and Risk Factors:
- Genetic mutations affecting the alpha IIb beta3 integrin gene
- Inherited in an autosomal recessive pattern

Signs and Symptoms
Glanzmann's Thrombasthenia: Signs and Symptoms
Glanzmann's thrombasthenia is a rare inherited blood clotting disorder that affects the function of platelets, leading to abnormal bleeding. The symptoms can vary greatly from person to person, but common signs include:
- Easy bruising: People with Glanzmann's thrombasthenia may experience frequent and severe bruising, even with minor injuries.
- Bleeding gums: Bleeding gums are a common symptom of the condition, which can be painful and lead to tooth loss if left untreated.
- Nosebleeds: Frequent nosebleeds are another sign of Glanzmann's thrombasthenia, which can be triggered by minor trauma or even spontaneously.
- Purple spots or patches on the skin: Petechiae (small red or purple spots) and ecchymoses (larger purple patches) may appear on the skin due to bleeding under the surface.
- Heavy menstrual periods: Women with Glanzmann's thrombasthenia may experience heavy or prolonged menstrual bleeding, which can be debilitating.
- Gastrointestinal bleeding: In some cases, people with Glanzmann's thrombasthenia may experience bleeding in the digestive tract, leading to symptoms like black tarry stools or blood in the stool.
These symptoms can range from mild to severe and may change over time. It is essential for individuals with suspected Glanzmann's thrombasthenia to consult a healthcare provider for proper diagnosis and management.

Treatment
Treatment Options for Glanzmann's Thrombasthenia
Glanzmann's thrombasthenia, a rare inherited bleeding disorder, requires careful management to prevent and treat bleeding episodes. While there is no specific cure for the condition, various treatments can help alleviate symptoms and improve quality of life.
- Platelet Transfusions: Platelet transfusions may be given to individuals experiencing severe bleeding episodes [8]. However, it's essential to note that platelet transfusions can lead to the development of antibodies against platelets in some patients, making future transfusions less effective [11].
- NovoSeven RT (coagulation Factor VIIa, recombinant): NovoSeven RT is a recombinant therapy indicated for Glanzmann's thrombasthenia when platelets don't work [6]. This treatment can help manage bleeding episodes and perioperative management in adults and children with the condition.
- Anti-fibrinolytic drugs: Anti-fibrinolytic drugs, such as tranexamic acid, may be used to decrease minor bleeding symptoms [14]. *
Recommended Medications
- Platelet Transfusions
- NovoSeven RT (coagulation Factor VIIa, recombinant)
- Anti-fibrinolytic drugs

Differential Diagnosis
Differential Diagnosis of Glanzmann's Thrombasthenia
Glanzmann's thrombasthenia (GT) is a congenital bleeding disorder caused by a defect and/or deficiency of the platelet integrin, alpha IIb beta3. The differential diagnosis of GT involves distinguishing it from other conditions that may present with similar symptoms.
Key Conditions to Consider:
- Afibrinogenemia: A rare deficiency of fibrinogen that can manifest with bleeding symptoms similar to those of GT.
- Hemophilia: A rare inherited blood clotting disorder caused by an inactive or deficient blood protein, usually factor VIII or IX.
- Bernard-Soulier Syndrome: A rare autosomal recessive disorder characterized by platelet dysfunction and bleeding symptoms.
- Adenosine Diphosphate (ADP) or Collagen Receptor Defects: Abnormalities of primary receptors or signaling pathways that can lead to platelet aggregation defects.
Diagnostic Features:
- GT is often diagnosed definitively due to its distinctive laboratory features, including a defect in the alpha IIb beta3 integrin.
- Afibrinogenemia and hemophilia may present with similar bleeding symptoms but have distinct laboratory features.
- Bernard-Soulier Syndrome and ADP or collagen receptor defects can be distinguished by specific platelet function tests.
