Thrombocytopenia (Low Platelet Count)
Thrombocytopenia is a disorder where people have too few platelets. With too few platelets in the bloodstream, the blood is unable to properly clot. People with thrombocytopenia may experience prolonged external and internal bleeding. Large purple bruises (ecchymoses) and small red skin spots (petechiae) in the skin and mouth are common in those with thrombocytopenia. Other symptoms of the disorder include bleeding gums, blood in bodily fluids, and fatigue. Thrombocytopenia most often arises from a different condition or treatment, such as alcoholism, autoimmune disease, cancer treatments, viruses (such as Hepatitis C and HIV), bone marrow diseases (such as leukemia and aplastic anemia), enlarged spleen, and exposure to toxic chemicals. In rare cases, thrombocytopenia is inherited.
If a doctor suspects a patient has a thrombocytopenia, a complete blood count (CBC) or platelet count test helps determine the concentration of platelets in a person's blood at a given time. Thrombocytopenia can be diagnosed by hematologists using advanced tests on platelet samples. Flow cytometry tests detect abnormalities by evaluating the characteristics of a platelet sample using targeted lasers and lights.
Treatments for low platelet counts include steroids like Prednisone, that can assist with platelet production. If a patient's low platelet count is caused by spleen problems, spleen removal (splenectomy) may be recommended. To treat the prolonged bleeding caused by thrombocytopenia, doctors frequently prescribe Dempressin, a hormone that promotes blood clotting. Antifibrinolytic medications such as tranexamic acid may also aid in the promotion of clotting and the prevention of bleeding. For patients with severe platelet disorders (either low platelet count and dysfunctional platelets), blood transfusions may be prescribed. Platelet blood transfusions deliver donated platelets to patients intravenously, replenishing the volume of functioning platelets.
Patients can also modify their lifestyle to better manage their disorder and minimize complications. Patients with low blood counts should avoid blood-thinning medications, alcohol, and activities that could lead to injury. Many people with thrombocytopenia can live healthy and fulfilling lives with proper treatment and precautions.
