What is pancytopenia?
Pancytopenia is a deficiency of all types of blood cells, including white blood cells, red blood cells, and platelets. It occurs when your body cannot produce enough blood cells because the bone marrow stem cells that form blood cells do not function normally. Pancytopenia has widespread effects on the entire body by leading to oxygen shortage as well as problems with immune function. Aplastic anemia is a medical term that refers to a decrease in production of all types of blood cells.

Pancytopenia occurs in two forms: idiopathic, in which the cause is not known, but is often autoimmune, meaning that the body attacks its own tissues as foreign substances; and secondary, often caused by environmental factors. Approximately half of all pancytopenia cases are idiopathic. In other cases, viral infections, radiation or chemotherapy treatments, drug reactions, and exposure to toxins may precipitate the development of pancytopenia.
Pancytopenia may develop slowly over time or suddenly, and it can progress in a variety of ways. Symptoms of pancytopenia can include bleeding, easy bruising, fatigue, shortness of breath, and weakness. The decrease in white blood cells, which are involved in the body’s defense, or immune, system, also leads to an increased risk of infection. Treatments for pancytopenia include drugs that suppress the immune system (immunosuppressant drugs) and bone marrow stimulant drugs, blood transfusion, bone marrow transplant, and stem cell replacement therapy.
In some cases, symptoms of pancytopenia can be severe or life-threatening. Seek immediate medical care (call 911) if you experience high fever, seizures or convulsions, difficulty breathing, heavy bleeding, or confusion or loss of consciousness for even a brief moment.
What are the symptoms of pancytopenia?
Symptoms of pancytopenia include generalized symptoms such as fatigue and weakness, as well as skin symptoms, such as easy bruising or rash. Bleeding, including nosebleeds, bleeding of the gums, unexplained bleeding, or bleeding of the internal organs, is common in pancytopenia.... Read more about pancytopeniasymptoms
What causes pancytopenia?
Pancytopenia can be caused by heredity, medications, or exposure to environmental contaminants such as radiation or arsenic. In approximately half of cases, called idiopathic cases, the exact cause of the pancytopenia is not known. It may be linked to an autoimmune disorder, in which the body’s immune system attacks its own tissues as foreign substances, or an environmental contaminant. In rare cases, pregnancy can lead to autoimmune processes that may trigger pancytopenia.... Read more about pancytopeniacauses
How is pancytopenia treated?
In very mild cases of pancytopenia, treatment may not be necessary. In moderate cases, blood transfusions may help restore blood cell counts; however, transfusions may become less effective over time. In severe cases, treatments such as bone marrow transplant and stem cell therapy may be required to restore the ability of bone marrow to produce blood cells. Such treatments are generally effective in younger patients, but older patients may also require the use of immunosuppressant drugs or drugs that stimulate the bone marrow....
