Several diseases and conditions can cause an increase in lymphocytes (lymphocytosis). According to the provided references, these include infections, cancers of the blood or lymphatic system, and autoimmune diseases.
Conditions That Increase Lymphocytes
Lymphocytes are a type of white blood cell that plays a crucial role in the immune system. Elevated levels of lymphocytes often indicate the body is fighting an infection or responding to another condition.
Here's a breakdown of diseases and conditions associated with increased lymphocyte counts:
-
Infections: Different types of infections can trigger an increase in lymphocytes.
- Bacterial infections
- Viral infections
- Other types of infections
-
Cancers of the Blood or Lymphatic System: Certain cancers affect the production and survival of lymphocytes, leading to elevated levels.
- Leukemia (e.g., Lymphocytic Leukemia)
- Lymphoma (e.g., Hodgkin's Lymphoma)
-
Autoimmune Diseases: These diseases cause the immune system to attack the body's own tissues, leading to chronic inflammation and an increase in lymphocytes.
- Autoimmune diseases causing ongoing, called chronic, swelling and irritation, called inflammation.
In summary, infections (bacterial, viral, or other), cancers of the blood or lymphatic system, and autoimmune diseases characterized by chronic inflammation can all lead to increased lymphocyte counts.
