| == Historical Perspective == | | ==[[Febrile neutropenia historical perspective|Historical Perspective]]== |
| In 1966, Bodey ''et al.'' first described the quantitative association between leukocyte counts and the incidence of infection in a study of acute leukemia which demonstrated that the risk and the type of infection are related to the severity and duration of granulocytopenia.<ref>{{Cite journal | issn = 0003-4819 | volume = 64 | issue = 2 | pages = 328–340 | last = Bodey | first = G.

| == Pathophysiology == | | ==[[Febrile neutropenia pathophysiology|Pathophysiology]]== |
| A number of factors pose an increased risk for infection in patients with neutropenic fever:
| |
|
| |
|
| * '''Absolute or functional leukopenia'''
| | ==[[Febrile neutropenia causes|Causes]]== |
| :: [[Leukocytes]], particularly [[neutrophils]], constitute one of the front-line defense mechanisms against invading [[microorganisms]]. [[Chemotherapy]] is associated with both qualitative and quantitative deficits in circulating neutrophils by lowering neutrophil counts and impairing [[chemotaxis]] and [[phagocytosis]], respectively. In addition, patients receiving [[glucocorticoid]]-containing regimens, [[calcineurin]] inhibitors, or [[fludarabine]] are also predisposed to infection as a consequence of lymphocyte dysfunction.
| |
|
| |
|
| * '''Altered microbiota'''
| | ==[[Febrile neutropenia epidemiology and demographics|Epidemiology and Demographics]]== |
| :: [[Microbiome|Microbiota]] that inhabit the skin, respiratory tract, and digestive tract may be altered by cancer and its treatment or the use of antibiotics.<ref>{{Cite journal | doi = 10.1056/NEJMct1210890 | issn = 1533-4406 | volume = 368 | issue = 12 | pages = 1131–1139 | last = Bennett | first = Charles L. | coauthors = Benjamin Djulbegovic, LeAnn B.

| |
|
| |
|
| * '''Breaches of natural barriers'''
| | ==[[Febrile neutropenia risk factors|Risk Factors]]== |
| :: [[Mucositis]] may occur as a direct adverse effect of [[chemotherapy]] or [[radiotherapy]] and disrupt the barrier function of the endothelial lining. Indwelling catheters and implanted devices allow access of skin [[commensal]]s into blood or subcutaneous tissues or serve as a [[biofilm]] which bacteria can colonize.
| |
|
| |
|
| * '''Immune defects associated with specific primary malignancies'''
| | ==[[Febrile neutropenia natural history, complications and prognosis|Natural History, Complications and Prognosis]]== |
| :: An increased risk of infection has been observed in patients with [[Hodgkin's lymphoma]] (as a result of defects in [[cell-mediated immunity]]) and in patients with [[chronic lymphocytic leukemia]] or [[multiple myeloma]] (as a result of [[hypogammaglobulinemia]]).

| Bloodstream infections caused by endogenous flora and reactivation of latent infections account for a majority of initial febrile episode in neutropenic patients with cancer. Common bacterial isolates that cause bacteremia in the setting of neutropenia are listed in Table 1.<ref>{{Cite journal | doi = 10.1007/s00277-011-1373-2 | issn = 1432-0584 | volume = 91 | issue = 5 | pages = 767–774 | last = Pagano | first = L. | coauthors = M.

| Fungal infections often take place in the setting of prolonged or profound neutropenia after administration of empirical therapy. Candidiasis may range in severity from mucosal or cutaneous infection to septicemia, endocarditis, or disseminated infection. Aspergillus, on the contrary, typically causes life-threatening infection of the sinuses and lungs, particularly after protracted neutropenia.<ref>{{Cite journal | doi = 10.1093/cid/ciq147 | issn = 1537-6591 | volume = 52 | issue = 4 | pages = 427–431 | last = Freifeld | first = Alison G. | coauthors = Eric J.

| == Epidemiology and Demographics ==
| |
| Approximately 10% to 50% of patients with solid tumors and more than 80% of those with hematologic malignancies will develop fever during courses of cytotoxic chemotherapy. However, an infectious etiology can be established in a minority of patients, and clinically defined infections occur in 20% to 30% of febrile episodes.<ref>{{Cite journal | doi = 10.1093/cid/ciq147 | issn = 1537-6591 | volume = 52 | issue = 4 | pages = 427–431 | last = Freifeld | first = Alison G. | coauthors = Eric J.

| Over the past few decades, there has been a shift in the spectrum of bacterial isolates from patients with febrile neutropenia. Gram-negative organisms prevailed in the era when cytotoxic chemotherapy was initially introduced, whereas Gram-positive skin flora including coagulase-negative staphylococci evolved as the most common isolates after widespread use of indwelling catheters and prophylactic antibiotics. In addition, there has been a drift in susceptibility patterns, with resistance seen in the general population of hospitalized patients now emerging in febrile neutropenic patients.<ref>{{Cite journal | doi = 10.1086/383048 | issn = 1537-6591 | volume = 39 Suppl 1 | pages = –25-31 | last = Ramphal | first = Reuben | title = Changes in the etiology of bacteremia in febrile neutropenic patients and the susceptibilities of the currently isolated pathogens | journal = Clinical Infectious Diseases: An Official Publication of the Infectious Diseases Society of America | date = 2004-07-15 | pmid = 15250017 }}</ref>

| High-risk patients as assessed by clinical judgment criteria or MASCC Risk Index are more likely to develop serious complications of febrile neutropenia including intensive care unit admission, confusion, cardiac complications, respiratory failure, renal failure, hypotension, bleeding, and death (Table 2).<ref>{{Cite journal | issn = 0022-1899 | volume = 161 | issue = 3 | pages = 397–401 | title = From the Immunocompromised Host Society.

| == Diagnosis ==
| |
| === Diagnostic Criteria ===
| |
| The definitions of [[fever]] and [[neutropenia]] are used to identify patients in whom empirical antibiotic therapy must be initiated. However, neutropenic patients represent a heterogeneous population and treatment may be considered even when they do not meet these specific criteria. Clinical judgment based on parameters in risk assessment also plays a critical role in tailoring the management.
| |
| | |
| ==== Fever ====
| |
| Fever is defined as a single oral temperature measurement of ≥38.3°C (101°F) or a temperature of ≥38.0°C (100.4°F) sustained over a 1-hour period.<ref>{{Cite journal | doi = 10.1093/cid/ciq147 | issn = 1537-6591 | volume = 52 | issue = 4 | pages = 427–431 | last = Freifeld | first = Alison G. | coauthors = Eric J.

| |
| | |
| ==== Neutropenia ====
| |
| Neutropenia is defined as an absolute neutrophil count (ANC) of <500 cells/mm<sup>3</sup> or an ANC that is expected to decrease to <500 cells/mm<sup>3</sup> during the next 48 hours.<ref>{{Cite journal | doi = 10.1093/cid/ciq147 | issn = 1537-6591 | volume = 52 | issue = 4 | pages = 427–431 | last = Freifeld | first = Alison G. | coauthors = Eric J.

| |
| | |
| ==== Profound neutropenia ====
| |
| Neutropenia in which the ANC is <100 cells/mm<sup>3</sup>; a manual reading of the blood smear is required to confirm this degree of neutropenia.<ref>{{Cite journal | doi = 10.1093/cid/ciq147 | issn = 1537-6591 | volume = 52 | issue = 4 | pages = 427–431 | last = Freifeld | first = Alison G. | coauthors = Eric J.

| |
| | |
| ==== Functional neutropenia ====
| |
| Functional neutropenia refers to patients whose hematologic malignancy results in qualitative defects (impaired [[phagocytosis]] and killing of pathogens) of circulating neutrophils. These patients should also be considered to be at increased risk for infection, despite a normal neutrophil count.<ref>{{Cite journal | doi = 10.1093/cid/ciq147 | issn = 1537-6591 | volume = 52 | issue = 4 | pages = 427–431 | last = Freifeld | first = Alison G. | coauthors = Eric J.

| |
| | |
| ==== Microbiologically defined infection ====
| |
| This can include both
| |
| # bacteremia, either with a single organism or polymicrobial infection, but without a definable nonhematogenous site of infection, and
| |
| # a microbiologically defined site of infection (e.g., pneumonia, cellulitis) with or without concomitant bacteremia.<ref>{{Cite journal | issn = 0022-1899 | volume = 161 | issue = 3 | pages = 397–401 | title = From the Immunocompromised Host Society.

| |
| | |
| ==== Clinically defined infection ====
| |
| This is designated when a site of infection is diagnosed (e.g., pneumonia,cellulitis) but its microbiologic pathogenesis either cannot be proven or is inaccessible to examination.<ref>{{Cite journal | issn = 0022-1899 | volume = 161 | issue = 3 | pages = 397–401 | title = From the Immunocompromised Host Society.

Report of a consensus panel | journal = The Journal of Infectious Diseases | date = 1990-03 | pmid = 2179421 }}</ref>
| |
| | |
| ==== Unexplained fever ====
| |
| In the neutropenic patient, this is defined as a new fever that is not accompanied by either clinical or microbiologic evidence of infection.<ref>{{Cite journal | issn = 0022-1899 | volume = 161 | issue = 3 | pages = 397–401 | title = From the Immunocompromised Host Society.

Report of a consensus panel | journal = The Journal of Infectious Diseases | date = 1990-03 | pmid = 2179421 }}</ref>
| |
| | |
| === History ===
| |
| Pertinent history should include new site-specific symptoms, prior use of antimicrobial agents, potential infection exposures, previous documented infections or pathogen colonization, catheter or device placement, and co-existence of noninfectious causes of fever, such as blood product administration. Underlying co-morbidities, such as diabetes, chronic obstructive lung disease, and/or recent procedures, should also be noted.
| |
| | |
| === Signs and Symptoms ===
| |
| In neutropenic patients, manifestations secondary to inflammation are attenuated and fever is often the only clue indicative of an underlying infection.
| |
| | |
| === Physical Examination ===
| |
| The physical examination should focus on potential sites of infection.
| |
| | |
| ==== Skin ====
| |
| Induration and erythema may be minimal. Pustule formation are uncommon in the absence of neutrophils.
| |
| | |
| ==== Throat ====
| |
| Examination of the oropharynx may reveal ulcers or plaques suggestive of herpes or candidiasis. Mucositis owing to cytotoxic chemotherapy may be indistinguishable from herpetic gingivostomatitis.
| |
| | |
| ==== Lungs ====
| |
| Auscultation of the lungs may reveal minimal adventitial sounds.
| |
| | |
| ==== Abdomen ====
| |
| Abdominal pain in neutropenic patients may herald an intraabdominal catastrophe secondary to neutropenic enterocolitis or tumor necrosis.
| |
| | |
| ==== Other ====
| |
| Examination of catheter sites may disclose erythema, tenderness, or discharge.
| |
| | |
| === Laboratory Tests ===
| |
| Complete blood cell count with differential white cell count and levels of serum creatinine and urea nitrogen are required for determining the severity of neutropenia and monitoring potential drug toxicity. These tests should be performed at least every 3 days during the initial course of antibiotic treatment. At least weekly monitoring of transaminase levels is advisable for patients with suspected hepatocellular injury or cholestatic disease. Routine test of inflammation markers, such as C-reactive protein, IL-6, IL-8, or procalcitonin, to guide clinical decisions is not recommended.
| |
| | |
| At least two sets of blood culture samples, each consisting of ~20 mL of blood divided into 1 aerobic and 1 anaerobic blood culture bottle, should be obtained from both a peripheral vein and from each catheter lumen. In pediatric patients, the total sample limit would be 7 mL for a 10-kg patient and 28 mL for a 40-kg patient. Drawing blood samples from both peripheral vein and catheter may help determine the source of infection. Culture for coagulase-negative staphylococci requires two positive results to be considered a "true positive." After initial defervescence occurs with empirical treatment, any recrudescent fever should be evaluated as a new episode of possible infection.<ref>{{Cite journal | doi = 10.1093/cid/ciq147 | issn = 1537-6591 | volume = 52 | issue = 4 | pages = 427–431 | last = Freifeld | first = Alison G. | coauthors = Eric J.

| |
| | |
| ==== Stool ====
| |
| A stool specimen in a patient with diarrhea should be evaluated with Clostridium difficile toxin assays. There is limited value in sending a stool specimen for bacterial pathogen cultures or for ova and parasite examination for most patients unless there has been recent travel to or residence in areas of endemicity.<ref>{{Cite journal | doi = 10.1093/cid/ciq147 | issn = 1537-6591 | volume = 52 | issue = 4 | pages = 427–431 | last = Freifeld | first = Alison G. | coauthors = Eric J.

| |
| | |
| ==== Urine ====
| |
| Culture of urine samples is indicated if signs or symptoms of urinary tract infection exist, a urinary catheter is in place, or the findings of urinalysis are abnormal.<ref>{{Cite journal | doi = 10.1093/cid/ciq147 | issn = 1537-6591 | volume = 52 | issue = 4 | pages = 427–431 | last = Freifeld | first = Alison G. | coauthors = Eric J.

| |
| | |
| ==== Cerebrospinal Fluid ====
| |
| Examination and culture of the cerebrospinal fluid is indicated if meningitis is suspected. Platelet transfusion may be considered prior to lumbar puncture if thrombocytopenia is a concern.<ref>{{Cite journal | doi = 10.1093/cid/ciq147 | issn = 1537-6591 | volume = 52 | issue = 4 | pages = 427–431 | last = Freifeld | first = Alison G. | coauthors = Eric J.

| The maximum value of the score is 26. <sup>a</sup> Burden of febrile neutropenia refers to the general clinical status of the patient as influenced by the febrile neutropenic episode. It should be evaluated on the following scale: no or mild symptoms (score of 5); moderate symptoms (score of 3); and severe symptoms or moribund (score of 0). Scores of 3 and 5 are not cumulative. <sup>b</sup> Chronic obstructive pulmonary disease means active chronic bronchitis, emphysema, decrease in forced expiratory volumes, need for oxygen therapy and/or steroids and/or bronchodilators requiring treatment at the presentation of the febrile neutropenic episode. <sup>c</sup> Previous fungal infection means demonstrated fungal infection or empirically treated suspected fungal infection.
| |
| |} | |
| | |
| [[Infectious Diseases Society of America| Infectious Diseases Society of America (IDSA)]] recommends that either the clinical judgment criteria or the MASCC assessment tool can be used to stratify risk for patients presenting with fever and neutropenia. Risk assessment should then inform decisions about the type of regimen and appropriate venue for delivery of empirical antibiotics, as well as the timing of hospital discharge. High-risk patients should initially receive IV empirical antibiotic therapy in the hospital, whereas low-risk patients may be candidates for oral and/or outpatient empirical antibiotic therapy.
| |
| | |
| === Clinical Judgment Criteria ===
| |
| Patients with febrile neutropenia can be stratified at presentation into those with '''high-risk''' versus '''low-risk''' for complications of severe infection by the clinical judgment criteria as follows:<ref>{{Cite journal | doi = 10.1093/cid/ciq147 | issn = 1537-6591 | volume = 52 | issue = 4 | pages = 427–431 | last = Freifeld | first = Alison G. | coauthors = Eric J.

| |
| | |
| ==== High-Risk Patient by Clinical Judgment Criteria ====
| |
| Patients with <u>any</u> of the following criteria are considered to be at '''high risk''' for serious complications during fever and neutropenia:
| |
| * Profound neutropenia (ANC ≤100 cells/mm<sup>3</sup>) anticipated to extend >7 days
| |
| * Presence of any co-morbid medical problems including but not limited to:
| |
| :— Hemodynamic instability
| |
| :— Oral or gastrointestinal mucositis that interferes with swallowing or causes severe diarrhea
| |
| :— Gastrointestinal symptoms, including abdominal pain, nausea and vomiting, or diarrhea
| |
| :— Neurologic or mental-status changes of new onset d Intravascular catheter infection, especially catheter tunnel infection
| |
| :— New pulmonary infiltrate or hypoxemia, or underlying chronic lung disease
| |
| * Evidence of hepatic insufficiency (defined as aminotransferase levels greater than 5 times of normal values) or renal insufficiency (defined as a creatinine clearance of less than 30 mL/min).
| |
| | |
| High-risk patients should be hospitalized and receive intravenous empirical antibiotic therapy.
| |
| | |
| ==== Low-Risk Patient by Clinical Judgment Criteria ====
| |
| Patients with <u>all</u> of the following criteria are considered to be at '''low risk''' for serious complications during fever and neutropenia:
| |
| * Neutropenia expected to resolve within 7 days
| |
| * No active medical co-morbidity
| |
| * Stable and adequate hepatic function and renal function.
| |
| | |
| In general, any patient who does not strictly fulfill criteria for being at low risk should be treated according to guidelines for high-risk patients. Low-risk patients may be candidates for oral and/or outpatient empirical antibiotic therapy.
| |
| | |
| === MASCC Risk Index ===
| |
| The Multinational Association for Supportive Care in Cancer (MASCC) scoring system is a summation of weighted factors, including patient age, history, outpatient or inpatient status, acute clinical signs, the presence of medical comorbid conditions, and severity of fever and neutropenia as assessed by burden of illness. The MASCC Risk Index can be used to identify subgroups of febrile neutropenic patients with '''high-risk (score <21)''' or '''low-risk (score ≥21)''' for serious complications and death (Table 3). It is also a means to determine which patients require prolonged hospitalization and which may be candidates for oral or once-daily IV regimens and/or for early discharge from the hospital to complete the antibiotic course as outpatients.<ref>{{Cite journal | issn = 0732-183X | volume = 18 | issue = 16 | pages = 3038–3051 | last = Klastersky | first = J. | coauthors = M.

| == Treatment == | | == Treatment == |
| 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]]). 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.
