High-risk for severe infection or complications (1 or more) |
ANC <500 cells/microL* anticipated to last for >7 days |
Evidence of hepatic insufficiency (aminotransferase levels >5 times normal values) |
Evidence of kidney function impairment (creatinine clearance <30 mL/min) |
Comorbid medical problems including, but not limited to:
|
Acute lymphoblastic leukemia in infant <12 months of age |
Acute myeloid leukemia |
Within 30 days of hematopoietic cell transplant¶ |
Low-risk for severe infection or complications (all) |
ANC <500 cells/microL expected to resolve within 7 days (ie, neutrophil count increasing) |
Stable and adequate hepatic function |
Stable and adequate kidney function |
No active comorbidities (as listed above) |
ANC: absolute neutrophil count; GI: gastrointestinal.
* The ANC threshold for high-risk defined herein differs from that in the 2010 Infectious Diseases Society of America guidelines (≤100 cells/microL anticipated to last >7 days[1]).
¶ Some centers extend this period to within 100 days of hematopoietic cell transplant.
