What is a neutropenic fever?

Neutropenic fever is a serious medical condition that occurs when a person with neutropenia, a low level of neutrophils in the blood, develops a fever. This condition is particularly dangerous because neutrophils are crucial for fighting off infections. Without enough neutrophils, the body is less able to combat infectious agents, making even minor infections potentially life-threatening.

Causes

Neutropenic fever is typically caused by an infection, which can be bacterial, viral, or fungal. Individuals undergoing chemotherapy or radiation therapy for cancer are particularly at risk, as these treatments can damage bone marrow, reducing neutrophil production. Other causes include bone marrow disorders, certain medications, and immune system diseases.

Symptoms

The symptoms of neutropenic fever are often subtle but can escalate quickly, necessitating immediate medical attention. Common symptoms include:

• Fever (usually above 100.4°F or 38°C)
• Chills or sweating
• Shortness of breath
• Sore throat
• Mouth sores
• Abdominal pain
• Diarrhea or changes in bowel habits

Diagnosis

Diagnosing neutropenic fever involves several steps to identify the cause and determine the best course of treatment:

1. Medical history and physical examination: Assessing the patient's symptoms, recent treatments, and overall health.
2. Complete blood count (CBC): To measure neutrophil levels.
3. Blood cultures: To identify potential bacterial infections.
4. Other cultures: Such as urine, stool, or sputum cultures to identify possible sources of infection.
5. Imaging tests: Such as chest X-rays or CT scans to detect any signs of infection or complications.

Neutropenic Fever Guidelines

Neutropenic fever is a critical condition commonly encountered in patients with cancer, particularly those undergoing cancer treatment. Effective management of this condition is crucial to prevent severe complications. This includes patients suffering from conditions like acute leukemia and acute myeloid leukemia, who are often at heightened risk due to chemotherapy-induced neutropenia.

Initial evaluation and risk assessment

Upon presentation of a fever in a patient after cancer treatment, it is crucial to manage them as neutropenic until proven otherwise. The initial evaluation of neutropenic patients includes checking vital signs, conducting a physical examination, and performing diagnostic tests such as blood cultures and a chest X-ray. Patients with profound neutropenia (ANC <100 cells/μL) or signs of systemic compromise are classified as high-risk.

Initial antibiotic management

Patients identified as high-risk patients should immediately receive initial empiric therapy. Common choices include piperacillin-tazobactam or cefepime as monotherapy. For low-risk patients, outpatient management of fever can be a safe and effective approach under strict monitoring guidelines.

For those allergic to penicillin, alternatives like aztreonam or ciprofloxacin plus vancomycin are recommended. Antibiotic therapy must be reassessed daily and adjusted based on culture results and the patient's clinical progression.

If initial antibiotic treatments do not resolve the fever, consider the possibility of invasive fungal infections, particularly in patients who remain neutropenic for extended periods, as these can complicate the clinical scenario significantly.

Supportive care

Patients with neutropenia should adhere to dietary restrictions to minimize the risk of foodborne infections. Consultations with specialists in infectious diseases may be necessary to address complex cases of neutropenic fever. Complete blood counts should also be monitored daily to track neutrophil recovery.
