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 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 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 causes leukopenia?

Leukopenia mainly has the following three causes: 1) Drugs; 2) Infections; 3) Diseases that cause disturbances in white blood cell production. Drugs primarily include antibiotics such as sulfonamide antibiotics and penicillin; anti-tuberculosis drugs like rifampicin and isoniazid; anti-thyroid drugs such as methimazole and propylthiouracil; antipyretic analgesics like aminopyrine, indomethacin, and ibuprofen; and antihistamines such as diphenhydramine. Additionally, most chemotherapy drugs can cause a decrease in white blood cells. Viral infections can lead to a decrease in white blood cells or severe bacterial infections, such as sepsis and septicemia, along with some chronic infections. Diseases that cause disturbances in the production of white blood cells mainly refer to certain hematological diseases, such as aplastic anemia or malignant tumors that invade the bone marrow and affect hematopoiesis. Furthermore, there are some less common causes of leukopenia, such as familial inheritance and granulocyte distribution disorders.

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 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.
