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.

How to treat leukopenia?

The treatment plan for leukopenia primarily depends on the cause of the decreased white blood cells. If the cause is related to blood cancer, further examinations like bone marrow biopsy are needed, followed by treatment of the primary disease. The second most common scenario is liver cirrhosis, which can lead to a decrease in all three blood cell lines, causing reduction in white blood cells, platelets, and hemoglobin. In such cases, treatment options may include splenectomy or the use of oral medications that increase white blood cell count. However, these treatments only address the symptoms and not the root cause, which is liver cirrhosis, thus the primary disease still requires treatment. The third scenario involves severe bacterial and viral infections, where a decrease in white blood cells indicates a serious condition, necessitating further antiviral or anti-infection treatments. (Please follow the guidance of a professional physician for medication use, and do not self-medicate.)

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.

Does leukopenia lead to leukemia?

First of all, a concept to clarify: generally, leukemia is associated with a very high white blood cell count. So, does a decrease in white blood cells lead to leukemia? There is no direct causal relationship between the two. A reduction in white blood cells generally requires an analysis of its cause—whether it is due to a decline in hematopoietic function, a deficiency in raw materials, or an increase in destruction. These situations essentially involve issues in the production factory or where they are used. We cannot say that people with reduced white blood cells will not develop leukemia, nor can it be stated in that way. They may also, over a period, exhibit a reduction in white blood cells due to certain factors. So, if there are genes causing leukemia combined with other factors, leukemia might occur, but there is no direct causation between the two.

Symptoms of leukopenia

The symptoms of leukopenia vary with the severity of the decrease in white blood cells and the disease causing the leukopenia. Mild leukopenia generally has no significant clinical manifestations. With moderate leukopenia, patients often experience symptoms of fatigue. If there is a significant decrease in white blood cells, patients often present with fever since white blood cells are the main cells in the body's defense against infections. A significant decrease in white blood cells markedly lowers the patient's resistance, thus making them more susceptible to various infections, with fever being the most common symptom of infection. Furthermore, the clinical presentations also vary with the underlying disease causing the decrease in white blood cells. For example, diseases like aplastic anemia or acute leukemia, which cause a decrease in white blood cells, may lead not only to fever but also to significant fatigue and bleeding manifestations.
