Lecture 12: Neutropenic Fever Flashcards
Define neutropenic fever
Temp >38.5 °C (101.4 °F) w/ ANC <500 cells/uL
Which drugs should be given as 1’ antibacterial prophylaxis in pt’s at high-risk for neutropenic fever to target P. aeruginosa and other gram negatives?
Fluoroquinolones: Levofloxacin or Ciprofloxacin
What are 4 AE’s you must be aware of when prescribing Fluoroquinolones?
- Proloned QT interval
- Tendon rupture
- ↑ risk of C. diff infection
Which drug should be given as primary antifungal prophylaxis in pt’s at high-risk for neutropenic fever, specifically for Candida?
Fluconazole
What are alternative antifungal agents to Fluconazole which can be used as primary antifungal prophylaxis in pt at risk of neutropenic fever?
Echinocandins (caspofungin, micafungin, anidulafungin)
What is the first-line antifungal for Aspergillus spp. as a secondary prophylaxis for neutropenic fever in pt’s w/ hx of prior fungal infection?
Voriconazole
Which 3 chemotherapeutics should you not combine Voriconazole with, why?
- Cytarabine or fludarabine
- Severe neurotoxicity with vincristine**
To continue an antifungal during chemotherapy, which 2 drugs can be used?
Amphotericin B and Echinocandin
How is a patient with suspected neutropenic fever managed initially?
- Give IV antibiotics until ANC is >1000 cells/mL
- Then can switch to oral Abx, only if pt is afebrile and tolerating meals w/o emesis
List the drugs which can be used as inpatient empiric IV antibiotic therapy in high-risk pt’s with neutropenic fever.
- Pipracillin + tazobactam
- Carbapenem (imipenem, meropenem, doripenem, ertapenem)
- Ceftazidime
- Cefepime
In pt with neutropenic fever + cellulitis or pneumonia, which 2 Abx should be given?
Vancomycin or linezolid
In pt with neutropenic fever and culutre of gram negative bactremia, which drug should be added to IV therapy?
Add Aminoglycoside (i.e., Gentamicin)
In pt with neutropenic fever and abdominal sx’s or suspected C. difficile which Abx should be added to IV regimen?
Metronidazole
What is the outpatient oral regimen for neutropenic fever in low-risk pt?
Ciprofloxacin + amoxicillin/clavulanic acid
If neutropenic fever does not resolve after 5 days with antibiotics alone what drug should be added?
Caspofungin; infection w/ Candida spp. most likely
