Febrile neutropenia

From WikiMD's Wellness Encyclopedia

(Redirected from Neutropenic fever)

Febrile neutropenia is a medical condition characterized by the development of fever, often with other signs of infection, in a patient with neutropenia, an abnormally low number of neutrophils in the blood. Neutrophils are a type of white blood cell crucial for combating infections. This condition is particularly common in patients undergoing chemotherapy for cancer, as these treatments can significantly reduce neutrophil counts.

Causes[edit | edit source]

Febrile neutropenia is most commonly caused by chemotherapy and other treatments that suppress the bone marrow, where neutrophils are produced. Other causes can include hematologic malignancies, bone marrow transplantation, and certain autoimmune diseases. Infections are a frequent trigger for fever in neutropenic patients, as their immune systems are compromised.

Symptoms[edit | edit source]

The primary symptom of febrile neutropenia is a fever, typically defined as a single oral temperature of 38.3°C (101°F) or a sustained temperature of 38.0°C (100.4°F) for more than an hour. Other symptoms may include chills, sweating, and signs of infection such as redness, swelling, or pain at a specific site.

Diagnosis[edit | edit source]

Diagnosis of febrile neutropenia involves a combination of clinical evaluation and laboratory tests. Blood tests are performed to confirm neutropenia and to identify any underlying infections. Blood cultures, urine cultures, and imaging studies such as chest X-rays may also be used to identify the source of infection.

Treatment[edit | edit source]

The treatment of febrile neutropenia typically involves the prompt administration of broad-spectrum antibiotics to combat potential infections. The choice of antibiotics may be adjusted based on the results of cultures and sensitivity tests. In some cases, granulocyte colony-stimulating factor (G-CSF) may be administered to stimulate the production of neutrophils. Hospitalization is often required for close monitoring and supportive care.

Prognosis[edit | edit source]

The prognosis for patients with febrile neutropenia varies depending on the underlying cause, the patient's overall health, and the promptness of treatment. Early and appropriate treatment can significantly improve outcomes, but severe infections and complications can still occur.

Prevention[edit | edit source]

Preventive measures for febrile neutropenia include the use of prophylactic antibiotics and antifungal agents in high-risk patients, as well as the administration of G-CSF to reduce the duration and severity of neutropenia. Good hygiene practices and avoiding exposure to infectious agents are also important preventive strategies.
