==Overview==
==[[Febrile neutropenia historical perspective|Historical Perspective]]==
'''Febrile neutropenia''' is the development of [[fever]], often with other signs of [[infection]], in a patient with [[neutropenia]], an abnormally low number of [[neutrophil granulocyte]]s (a type of [[white blood cell]]) in the blood. The term '''neutropenic sepsis''' is also applied, although it tends to be reserved for patients who are less well. In 50% of cases, an infection is detectable; [[bacteremia]] (bacteria in the bloodstream) is present in approximately 20% of all patients with this condition.<ref name="pmid11850858">{{cite journal |author=Hughes WT, Armstrong D, Bodey GP, ''et al.'' |title=2002 guidelines for the use of antimicrobial agents in neutropenic patients with cancer |journal=Clin.

==Causes==
==[[Febrile neutropenia pathophysiology|Pathophysiology]]==
Febrile neutropenia can develop in any form of neutropenia, but is most generally recognized as a complication of [[chemotherapy]] when it is [[myelosuppressive]] (suppresses the [[bone marrow]] from producing blood cells).


==Multinational Association for Supportive Care in Cancer (MASCC) Risk Index==
==[[Febrile neutropenia causes|Causes]]==
The Multinational Association for Supportive Care in Cancer (MASCC) Risk Index can be used to identify high-risk patients (score <21) and low-risk patients (score ≥21 points) for serious complications of febrile neutropenia (including death, [[intensive care unit]] admission, confusion, cardiac complications, [[respiratory failure]], [[renal failure]], [[hypotension]], [[bleeding]], and other serious medical complications).<ref name="pmid10944139">{{cite journal |author=Klastersky J, Paesmans M, Rubenstein EB, ''et al.'' |title=The Multinational Association for Supportive Care in Cancer risk index: A multinational scoring system for identifying low-risk febrile neutropenic cancer patients.|journal= J Clin Oncol. |volume=18 |issue=16 |pages=3038–51 |date=16 August 2000|pmid=10944139| url=http://jco.ascopubs.org/cgi/content/full/18/16/3038 |issn=0732-183X}}</ref>  The score was developed to select patients for therapeutic strategies that could potentially be more convenient or cost-effective.  The various variables and the weight of individual variables used in the MASCC risk index is as follows.  To summarize, risk assessment helps determining the type of empirical antibiotic therapy, venue of the treatment, and duration of the antibiotic therapy.

A prospective trial demonstrated that a modified MASCC score can identify patients with febrile neutropenia at low risk of complications as well.<ref name="pmid17960431">{{cite journal |author=de Souza Viana L, Serufo JC, da Costa Rocha MO, Costa RN, Duarte RC |title=Performance of a modified MASCC index score for identifying low-risk febrile neutropenic cancer patients |journal=Supportive Care in Cancer : Official Journal of the Multinational Association of Supportive Care in Cancer |volume=16 |issue=7 |pages=841–6 |year=2008 |month=July |pmid=17960431 |doi=10.1007/s00520-007-0347-3 |issn=0941-4355}}</ref>

==Treatment==
==[[Febrile neutropenia natural history, complications and prognosis|Natural History, Complications and Prognosis]]==
Generally, patients with febrile neutropenia are treated with empirical [[antibiotic]]s until the neutrophil count has recovered (Absolute neutrophil counts greater than 500/mm3) and the fever has abated; if the neutrophil count does not improve, treatment may need to continue for two weeks or occasionally more. In cases of recurrent or persistent fever, an antifungal agent should be added.


Guidelines issued in 2002 by the [[Infectious Diseases Society of America]] recommend the use of particular combinations of antibiotics in specific settings; mild low-risk cases may be treated with a combination of oral [[co-amoxiclav]] and [[ciprofloxacin]], while more severe cases require [[cephalosporin]]s with activity against ''[[Pseudomonas aeruginosa]]'' (e.g. [[cefepime]]), or [[carbapenem]]s ([[imipenem]] or [[meropenem]]).<ref name="pmid11850858"/> A subsequent [[meta-analysis]] published in 2006 found that [[cefepime]] was associated with more negative outcomes, and that carbapenems (while causing a higher rate of [[pseudomembranous colitis]]) were the most straightforward in use.<ref name="pmid16344285">{{cite journal |author=Paul M, Yahav D, Fraser A, Leibovici L |title=Empirical antibiotic monotherapy for febrile neutropenia: systematic review and meta-analysis of randomized controlled trials |journal=J.

In 2010, an updated guidelines was issued by the [[Infectious Diseases Society of America]], recommending use of cefepime, carbapenems (meropenem and imipenem/cilastatin), piperacillin/tazobactam for high risk patients and [[co-amoxiclav]] and [[ciprofloxacin]] for low risk patients. Patients who do not strictly fulfill the criteria of 'low risk patients' should be admitted to the hospital and treat as high risk patients.
