Leukopenia
Leukopenia and thrombocytopenia are what diseases
Diseases caused by decreased white blood cells and platelets are often related to our hematological system, since both white blood cells and platelets are produced by our hematopoietic factors. When there is a decrease in both white blood cells and platelets, we generally consider that there might be an issue with our hematopoietic system. The most common conditions could be diseases related to the hematological system, such as leukemia, or aplastic anemia. These conditions can cause a decrease in the mentioned indices. Another disease is cirrhosis, especially in patients in the compensatory stage, which can lead to hyperfunctioning of the spleen. The spleen is also an immune organ, as well as a part of our hematopoietic system, so when the spleen is hyperactive, it can also result in decreased white blood cells and platelets.
What causes leukopenia?
When the white blood cell count in the surrounding blood continuously remains below 4.0*10^9/L, we call this condition leukopenia. Typical symptoms of leukopenia include dizziness, fatigue, limb soreness, reduced appetite, and listlessness, although some patients may not exhibit any obvious clinical symptoms. The causes of leukopenia are very complex and can be classified into two main categories: primary and secondary. Primary leukopenia refers to cases where the cause is unknown, while secondary leukopenia refers to cases potentially caused by acute infections or physical and chemical factors, or diseases of the hematopoietic system, connective tissue diseases, allergic diseases, or genetic diseases, all of which may lead to a reduction in white blood cells.
What are the causes of leukopenia?
When the white blood cell count in peripheral blood is below 4.0 times 10 to the ninth power per liter, it is termed leukopenia. According to the cause, it can be divided into the following three aspects: First, disturbance in the production of white blood cells, including reduced proliferation of stem cells or regeneration disorders. Second, excessive destruction of white blood cells, such as from infections or immunological factors, leading to increased destruction of white blood cells. Third, abnormal distribution of white blood cells, due to various reasons, causes an increase in white blood cells in the marginal pool and a decrease in the circulating pool, which can also lead to leukopenia.
