Glanzmann disease
Glanzmann's diasease; Thrombasthenia - Glanzmann
Glanzmann disease is a rare disorder of blood platelets , which results in easy bruising and nosebleeds .
Platelets
A platelet count is a lab test to measure how many platelets you have in your blood. Platelets are parts of the blood that help the blood clot. The...
Bruising
Bleeding into the skin can occur from broken blood vessels that form tiny red dots (called petechiae). Blood also can collect under the tissue in la...
Nosebleeds
A nosebleed is loss of blood from the tissue lining the nose. Bleeding most often occurs in 1 nostril only.
Causes
Glanzmann disease is caused by the lack of a protein that is normally on the surface of platelets. This substance is needed for platelets to clump together to form blood clots.
The condition is congenital, which means it is present from birth. There are several genetic abnormalities that can cause the condition.
Symptoms
Symptoms may include any of the following:
- Heavy bleeding during and after surgery
- Bleeding gums
- Bruising easily
- Heavy menstrual bleeding
- Nosebleeds that do not stop easily
- Prolonged bleeding with minor injuries
Exams and Tests
The following tests may be used to diagnose this condition:
-
Complete blood count
(CBC)
Complete blood count

-
Bleeding time
Bleeding time
Bleeding time is a medical test that measures how fast small blood vessels in the skin stop bleeding.
-
Platelet aggregation tests
Platelet aggregation tests
The platelet aggregation blood test checks how well platelets, a part of blood, clump together and cause blood to clot.
-
Prothrombin time
(PT) and
partial thromboplastin time
(PTT)
Prothrombin time
Prothrombin time (PT) is a blood test that measures the time it takes for the liquid portion (plasma) of your blood to clot. A related blood test is ...
Partial thromboplastin time
Partial thromboplastin time (PTT) is a blood test that looks at how long it takes for blood to clot. It can help tell if you have a bleeding problem...
Other tests may be needed. Family members may also need to be tested.
Treatment
There is no specific treatment for this disorder. Platelet transfusions may be given to people who are having severe bleeding.
Outlook (Prognosis)
Glanzmann disease is a lifelong condition, and there is no cure. You should take special steps to try to avoid bleeding if you have this condition.
Anyone with a bleeding disorder should avoid taking aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and naproxen. These drugs can prolong bleeding times by preventing platelets from clumping.
Possible Complications
Complications may include:
- Severe bleeding
-
Iron deficiency anemia
in menstruating women due to abnormally heavy bleeding
Iron deficiency anemia
Anemia is a condition in which the body does not have enough healthy red blood cells. Red blood cells provide oxygen to body tissues. There are man...
When to Contact a Medical Professional
Call your health care provider if:
- You have bleeding or bruising of an unknown cause

Prevention
Glanzmann disease is an inherited condition. There is no known prevention.
