Introduction
In general, fever refers to an elevated body temperature. Recurrent fever accompanied by low white blood cell count may be associated with factors such as influenza, hand-foot-and-mouth disease, leukopenia, systemic lupus erythematosus, or leukemia. Patients are advised to receive symptomatic treatment as directed by a physician. It is recommended that patients seek timely medical evaluation at a hospital to determine the underlying cause and follow the doctor's instructions for appropriate treatment.
Generally, fever refers to an elevated body temperature. Recurrent fever accompanied by low white blood cell count may be associated with factors such as influenza, hand-foot-and-mouth disease, leukopenia, systemic lupus erythematosus, and leukemia. Patients are advised to follow medical instructions for symptomatic treatment. Specific analyses are as follows:
1. Influenza
Influenza testing may reveal decreased white blood cell count, which is one of the pathological indicators in routine blood tests. This is primarily due to invasion of the body by the influenza virus, triggering an inflammatory response. Under medical guidance, patients may take medications such as Lanqin Oral Liquid or Isatis Root Granules for treatment.
2. Hand-Foot-and-Mouth Disease
Hand-foot-and-mouth disease is an acute exanthematous illness caused by enterovirus infection. The virus enters the human bloodstream via the digestive or respiratory tract, stimulating white blood cells to release endogenous pyrogens, leading to recurrent fever and a low white blood cell count. Under medical guidance, patients may take medications such as ibuprofen capsules or acetaminophen tablets for treatment.
3. Leukopenia
Leukopenia commonly presents with symptoms including fatigue, palpitations, dizziness, muscle weakness in the limbs, insomnia, and vivid dreams. Clinically, it may also manifest as reduced white blood cell count during screening. Under medical guidance, patients may take medications such as berbamine hydrochloride tablets or mannatope polypeptide oral solution for treatment.
4. Systemic Lupus Erythematosus
Damage to the hematologic system caused by lupus can lead to decreased white blood cell counts, accompanied by symptoms such as fever and loss of appetite. Under medical guidance, patients may take medications such as hydroxychloroquine sulfate tablets or compound cyclophosphamide tablets for treatment.
5. Leukemia
Concurrent viral or bacterial infections in leukemia patients can cause fever and reduced white blood cell counts. Under medical guidance, patients may be treated with medications such as fludarabine phosphate for injection or ifosfamide for injection.
Patients are advised to seek timely medical evaluation at a hospital, identify the underlying cause, and follow the doctor's instructions for appropriate treatment.
