Introduction
Possible causes of low white blood cell count in patients with systemic lupus erythematosus include infection, fever, and weakness. Immune system dysregulation leads to infection, fever triggers inflammatory responses, and weakness results in the consumption of large amounts of energy and nutrients. In addition, a tendency to bleed may also contribute to reduced white blood cell levels. Treatment requires following medical advice for medication, nutritional supplementation, and timely medical care.

In general, low white blood cell count in systemic lupus erythematosus (SLE) may be caused by symptoms such as infection, fever, or weakness, requiring targeted treatment. A detailed analysis is as follows:

1. Infection

Patients with systemic lupus erythematosus have abnormal immune function, causing white blood cells in the immune system to lose their ability to clear bacteria and viruses, leading to infections and consequently reducing white blood cell counts. Under a doctor's guidance, white blood cell growth factors can be used to stimulate bone marrow hematopoietic function.

2. Fever

Fever in patients with systemic lupus erythematosus triggers inflammatory responses, during which the body produces large amounts of inflammatory mediators such as interleukins and interferons. These substances suppress the growth and differentiation of hematopoietic stem cells, resulting in decreased white blood cell counts. Medications such as ibuprofen capsules or cyclophosphamide granules may be used as directed by a physician.

3. Weakness

Exacerbated internal inflammatory responses in patients increase metabolic rates, consuming substantial energy and nutrients, thereby elevating metabolic activity. This leads to symptoms such as fatigue and weakness, which can also impair hematopoietic function and result in reduced white blood cell counts. Under medical advice, supplements such as vitamin B12 tablets or folic acid tablets may be used to improve nutritional status.

Besides the above, conditions such as bleeding tendencies or abnormal bone marrow infections can also lead to low white blood cell counts. Patients should seek timely medical attention to prevent worsening of the condition.
