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.

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.

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.

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.
