OUTLINE

1. Definitions and Criteria

Fever : single oral temp. > 38.3 0C ora temp. >38.0 0C for > 1 hr

Neutropenia : neutrophil count < 500 /mm3 , or account of < 1,000 with a predicted decrease to < 500

Walter at al, Infect Desease Society of America. 2002; 34: 731-751Hughes at al, Clin Infect Diss 2002; 52: 551-73

Febrile NeutropeniaLow Risk

• ANC > 100 /mm3• Normal CXR • Duration of neutropenia < 7 d • Resolution of neutropenia <10 d • No appearance of illness • No comorbidity complications • Malignancy in remission

Walter at al, Infect Desease Society of America. 2002; 34: 731-751Hughes at al, Clin Infect Diss 2002; 52: 551-73

High Risk Patients

• Parenteral antibiotics + close monitoring• Haematological malignancies• Severe and prolonged neutropenia > 10 d• Evidence of shock / dehydration• Mucositis preventing oral hydration• Complex focal infection eg CVL site infection• Respiratory / gastrointestinal involvement• Need for blood products• Renal / hepatic insufficiency • Change in mental status

Hughest et al, Guideline for febrile neutropenia. 2002; 34: 734-752

Preantibiotic Investigations

• Blood C/S : central line & peripheral • Chest X-Ray • Urine C/S • Stool C/S • Biopsy cultures • Viral studies

2. INITIAL EVALUATION

Possible sites of infection• URTI • Dental sepsis • Mouth ulcers • Skin sores • Exit site of central venous catheters • Anal fissures • GI

Febrile NeutropeniaBacterial causes

• Gram-positive bacteria (60-70%)

Staphylococcus spp : MSSA,MRSA, Enterococcus faecalis/faecium Corynebacterium spp Bacillus spp Stomatococcus mucilaginosus

• Gram-negative bacilli (30-40%) Escherichia coli Klebsiella spp : ESBL Pseudomonas aeruginosa Enterobacter spp Acinetobacter spp Citrobacter spp Stenotrophomonas maltophilia

• Anerobic BacteriaBacteroides spp Clostridium spp Fusobacterium spp Propionibacterium spp Peptococcus spp Veillonella spp Peptostreptococcus sppDel Favero at al, Clin infect Dis. 2001; 33: 1295-301

Weinstein et al, J. Clin Microbiol. 2006; 32:2103-6

3. WHO SHOULD RECEIVE EMPIRICAL TX?

• Bacterial infection • Neutropenia :single most important risk factor for infection in cancer. • Risk of infection increases 10-fold with declining neutrophil counts < 500/mm3• 48-60% : occult infection • 16-20% with neutropenia <100/mm3 have bacteremia

Samam MD. Commun Oncol 2006; 3 : 585-591

4. Initial Empiric AntibioticsConsiderations

• Broad spectrum of bactericidal activity • Local prevalence, susceptibility pattern• Antibiotic toxicity : well-tolerated, allergy • Host factors : severity of presentation • Prior antibiotic usage • Antibiotic costs • Ease of administration

5. Initial Empiric Antibiotics Recommended choices 1. Monotherapy

• Antipseudomonal Ceph 3 : ceftazidime • Ceph 4 : cefepime • Carbapenem : imipenem , meropenem

2. Combination • Duo therapy without vancomycin• Vancomycin plus one or two drugs

Lindbad et al, Scand J Infect Dis. 2005; 30: 237-43Liat V et al, J Antimimicrobial Chem . 2004; 54:29-31Hughest et al, Guideline for febrile neutropenia. 2002; 34: 734-752

• Aminoglycoside + Anti-pseudomonal carboxypenicillin (Piperacillin – Tazobactam + Gentamycin, Tobramycin, Amikacin or Ticarcillin-clavulanic acid + Aminoglycoside)• Aminoglycoside + Anti-pseudomonal Cephalosporin• Aminoglycoside + Carbapenem

Initial Antibiotic ModificationsConsiderations

• Persistence of fever • Clinical deterioration • Culture results • Drug intolerance/side effects

Combination TherapyAdvantages

• Increased bactericidal activity • Potential synergistic effects • Broader antibacterial spectrum • Limits emergence of resistance

Combination TherapyDisadvantages

• Drug toxicities • Drug interactions • Potential cost increase • Administration time

Persistent FeverCauses • Nonbacterial infection• Resistant bacteria • Slow response to antibiotics • Fungal sepsis • Inadequate serum & tissue levels • Drug fever Jasic et al, Clin Infect Dis .2006; 42:597-607

7. Duration of Antibiotic Therapy

When to stop?

• No infection identified after 3 days of Rx • ANC > 500 for 2 consecutive days • Afebrile > 48 hr • Clinically well

Jasic et al, Clin Infect Dis .2006; 42:597-607

Stop if no disease and condition stable

Stop when afebrile for 5- 7 days

Guide for the management of patients with persistent fever during antibiotic therapy

Reproduced with permission from Hughes et al. Clin Infect Dis 2002;34:730–751

Antifungal drug, with or without

antibiotic change

If febrile through Days

5–7 and resolution of

neutropenia is not imminent

Persistent fever during first 3–5 days of treatment: no aetiology

Reassess patient on Days 3–5

• If progressive disease or

• If criteria for vancomycin are met

Change antibiotics

If no change in patient's condition (consider stopping

vancomycin)

Continue initial

antibiotics

Guidelines Febrile Neutropenia

Antibiotics penetration :

Cunha , Antibiotic Essential, 2009

Febrile NeutropeniaConclusions

• Significant morbidity & mortality • Choice of initial empiric therapy dependent on epidemiologic & clinical factors • Monotherapy as efficacious as combination Rx• Modifications upon reassessment • Duration dependent on ANC
