CMV after hematopoietic stem cell transplantation
From IDWiki
Management
- Most frequently managed with weekly viral loads and preemptive treatment (PET) at a lab-specific threshold
- Antiviral treatment:
- ganciclovir 5 mg/kg q12h for 7 to 14 days (induction) followed by valganciclovir 900 mg po daily (maintenance) until a few weeks after viremia resolves
- If concerns about oral antiviral, would continue ganciclovir 5 mg/kg IV daily (maintenance)
- If ganciclovir resistance, next step is foscarnet 90 mg/kg IV q12h (induction) followed by q24h (maintenance)
- Major adverse effect of ganciclovir is bone marrow suppression
- Use CMV safe (leukoreduced or filtered) blood products if the recipient is CMV seronegative
| Serostatus | Blood products | Duration of PET |
