Human Herpesvirus Type 6 Medication
- Author: Michelle R Salvaggio, MD; Chief Editor: Burke A Cunha, MD more...
Medication Summary
- The role of antiviral therapy for human herpesvirus 6 (HHV-6) infection has yet to be determined.
- Therapy is usually unnecessary in primary infection in immunocompetent hosts.
- In immunosuppressed hosts in whom active HHV-6 infection has been documented, some studies have suggested using antiviral therapy in cases of hepatitis, bone marrow suppression, pneumonitis, or encephalitis. In particular, they recommend ganciclovir or foscarnet. Ganciclovir has also been reported to be beneficial against HHV-6 reactivation in patients undergoing stem cell transplantation.
Antivirals
Class Summary
Nucleoside analogs are initially phosphorylated by viral thymidine kinase to eventually form a nucleoside triphosphate, resulting in the inhibition of viral replication.
Ganciclovir (Cytovene, Vitrasert)
Acyclic nucleoside analog of 2'-deoxyguanosine that inhibits replication of herpes viruses both in vitro and in vivo.
Foscarnet (Foscavir)
Organic analog of inorganic pyrophosphate that inhibits replication of known herpesviruses. Inhibits viral replication at pyrophosphate-binding site on virus-specific DNA polymerases. Poor clinical response or persistent viral excretion during therapy may be due to viral resistance.
