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.

Is leukopenia very harmful?

Leukopenia primarily depends on the extent of the decrease in white blood cells, which can be classified into mild, moderate, and severe levels. Mild leukopenia generally means less than 4.0 X 10⁹/L, and if granulocytes are decreased, it typically means an absolute value of granulocytes less than 2.0 X 10⁹/L. A lack of granulocytes indicates a more severe condition, usually less than 0.5 X 10⁹/L. For patients with mild leukopenia, special preventive measures are generally not necessary. However, for moderate and severe leukopenia, the greatest risk is an increased chance of infection, as white blood cells are a marker of our ability to defend against external threats. With fewer of these defensive guards, the probability of resisting infections and the chance of acquiring infections significantly increase. Therefore, for patients with moderate leukopenia, their rate of infection increases, and it is important to take precautions, reduce visits to public places, maintain hygiene, and eliminate chronic infectious foci. For patients with severe leukopenia, aseptic isolation measures should be adopted. For patients who have infections, it is crucial to find sensitive antibiotics, preferably broad-spectrum antibiotics. If there is a concurrent fungal or viral infection, antifungal or antiviral medications should also be used, as the decrease in white blood cells can destroy a person's immune capacity, lowering immunity and increasing the chance of infections and the invasion of pathogenic bacteria, which in severe cases could even lead to sepsis or septic shock.

What medicine is used for leukopenia?

Leukopenia refers to a condition where the absolute count of white blood cells in peripheral blood persistently falls below 4.0×10^9/L, commonly known as leukopenia. There are many causes of leukopenia, which can generally be divided into two categories: defects in white blood cell production, and excessive destruction or consumption. Common causes include certain chemicals, radiation, cytotoxic drugs, some hematological diseases such as aplastic anemia and myelodysplastic syndrome, as well as Vitamin B12 deficiency, and drugs used to treat hyperthyroidism. Additionally, viral infections can lead to excessive white blood cell consumption and result in leukopenia. Therefore, when leukopenia occurs, it is crucial to actively search for the underlying causes and treat the primary condition. Meanwhile, if the patient's white blood cell count is significantly reduced, drugs that increase white blood cells may be temporarily administered to elevate the patient's white blood cell count.

Is leukopenia leukemia?

Leukopenia is not necessarily indicative of leukemia. There are many causes for a decrease in white blood cells, some of which can be due to medications. Currently, many drugs can cause a reduction in white blood cells, and in such cases, stopping the drug will typically allow the white blood cells to return to normal. A second scenario, especially in patients with an enlarged spleen or those suffering from cirrhosis, can also lead to a decrease in white blood cells. In these cases, it is mainly the abnormal function of the spleen that causes the reduction in white cells. Additionally, there are blood-related diseases, which might be leukemia or other types of blood disorders. In these situations, not only is there a reduction in white blood cells, but there is also a decrease in hemoglobin and platelets. Moreover, a significant increase in white blood cells is also a manifestation of leukemia, thus a decrease in white cells is not definitively indicative of leukemia.

What to check for the cause of leukopenia?

If there is a decrease in white blood cells, we mainly look at the total number of white blood cells and the absolute value of neutrophils in our routine blood test. The causes of leukopenia are inseparable from neutrophils, and can be mainly divided into three categories. The first category is a production defect of neutrophils, the second is excessive destruction and consumption of neutrophils, and the third is abnormal distribution of neutrophils. A major cause of decreased production of white cells and neutrophils is damage to hematopoietic stem cells by ionizing chemicals. Additionally, immune reactions and bone marrow diseases can also lead to decreased production. Another cause is a production defect due to maturation disorders in neutrophils within white blood cells, leading to reduced white blood cell production. Maturation disorders are mainly due to a lack of raw materials needed for white blood cell production. Excessive destruction and consumption of white blood cells are often due to immune factors. Immune factors are common in autoimmune diseases, thus such diseases can also lead to leukopenia. The last category, abnormal distribution, can be a severe infection that causes an abnormal distribution of white cells, retaining them alongside other substances, such as in patients with enlarged spleens, which can provoke leukopenia by causing granulocytes to be retained in circulation, especially in areas like the spleen.

What are the dangers of leukopenia?

Leukopenia is a relatively common hematological disease that can occur at any age. It is characterized by a persistent peripheral blood white blood cell count below 4×10^9/L. The onset of the disease is mostly slow, with mild symptoms. Common symptoms include fatigue, palpitations, dizziness, and pharyngitis, making individuals more susceptible to pharyngitis or mucosal ulceration. Other symptoms include reduced appetite, limb soreness, insomnia, and frequent dreaming. Individuals with leukopenia are also more prone to viral and bacterial infections. Some infections can lead to severe symptoms such as high fever, chills, and body aches. However, if there is a significant decrease in the total number of white blood cells, with the absolute neutrophil count dropping below 0.5×10^9/L, this condition is referred to as neutropenia. In such cases, symptoms may include chills, high fever, sore throat, headache, joint pain, and in severe cases, it can even lead to death.
