If you have mild lymphocytopenia with no underlying cause, you may not need treatment. The disorder may improve on its own.
If you have unusual infections, repeat infections, and/or infections that won't go away due to lymphocytopenia, you'll need treatment for the infections.
If you have a disease or condition that's causing lymphocytopenia, your doctor will prescribe treatment for that illness. Treating the underlying problem will help treat the lymphocytopenia.
A low lymphocyte count makes it hard for your body to fight infections. You may get infections caused by viruses, fungi, parasites, or bacteria.
Treatment for an infection will depend on its cause. You also may need treatment after an infection is gone to help prevent repeat infections.
Children who have serious, ongoing bacterial infections may get a medicine called immune globulin. This medicine helps boost the immune system and fight infections.
Many diseases and conditions can cause lymphocytopenia. Examples include infectious diseases, such as AIDS; blood diseases, such as aplastic anemia; and inherited diseases, such as Wiskott-Aldrich syndrome.
Your treatment will depend on your underlying disease or condition.
Researchers are looking at ways to increase lymphocyte production in people who have lymphocytopenia with serious underlying conditions.
For example, some studies are looking into blood and marrow stem cell transplants. This procedure may help treat or cure some of the conditions that can cause a low lymphocyte count.
Other studies are looking at medicines and other substances that can help the body make more lymphocytes.
