Controlled studies are needed to determine the benefit of antiviral therapy in patients with high viral >10,000 copies/ mL.
After screening 100,000 compounds, Merck identified a potent broad-spectrum herpesvirus antiviral
The new small molecule non-nucleoside inhibitor was effective in both in vitro and in vivo studies although no testing against HHV-6 was reported.
Why does substituting CMV-specific letermovir for broad-spectrum anti-viral prophylaxis reduce the rate of HHV-6B encephalitis?
Japanese study replicates the paradoxical results of a prior US study, but fails to explain the paradox.
Metformin reduces HHV-6A replication in T cells by activating AMPK
Conversely, HHV-6A infection increases viral replication by inhibiting AMPK and enhancing mTOR signaling and glycolysis.
Adding antithymocyte globulin to post transplant cyclophosphamide prophylaxis does not increase risk of HHV-6 reactivation after haploidentical hematopoietic cell transplantation
The main risk factor for HHV-6 reactivation was low absolute lymphocyte count.
MS drug teriflunomide dramatically reduces antibody titers to EBV and HHV-6
Study results are consistent with a pathogenetic role for viruses in relapsing-remitting MS.
Strong Evidence Linking HHV-6B To Pneumonia in Transplant Patients
Levels of mRNA transcripts indicating active infection strengthen case for pathogenic role.
Substituting letermovir for broad-spectrum ganciclovir for CMV prophylaxis did not increase HHV-6 disease in allogenic transplant patients
Investigators were surprised that the use of the less toxic CMV specific antiviral did not result in a significant increase in HHV-6-related disease.
Small study finds relatively high foscarnet concentrations in CSF in HHV-6 encephalitis
CSF foscarnet concentrati.ons were very near IC50 and were followed by sharp reductions in viral load.
Artesunate compares favorably to herpesvirus antivirals in suppressing HHV-6 and HHV-7
Non-randomized study finds somewhat more potent reduction of virus in leucocytes over several months of treatment.
Failure to detect iciHHV-6 leads to overtreatment in hematopoietic cell transplant recipients
Mistaking iciHHV-6 for a marked reactivation of naturally-acquired infection can lead to unnecessary diagnostic procedures and treatments, with adverse effects.
Foscarnet prophylaxis improved engraftment and survival in cord blood transplant patients
Six-month overall survival was 96% in the treated group compared to 72% in the untreated group.
Oral brincidofovir prophylaxis for CMV decreased incidence of HHV-6B viremia
Allogenic transplant patients who received prophylactic oral brincidofovir as part of a CMV trial had a reduced HHV-6B reactivation and lower viral loads.
Mori lab identifies a vaccine and immunotherapy target for HHV6-B
Rational vaccine design requires understanding details of protective immunity against each virus. Yasuko Mori and associates from Japan have now identified CD4+ and H-2Kd restricted CD8+ T-cell epitopes essential for HHV-6B viral entry, opening new possibilities for vaccines and immunotherapy.
Breakthrough on therapeutic HHV-6B neutralizing antibodies
Yasuko Mori and colleagues were successful in humanizing two neutralizing monoclonal antibodies to HHV-6B. The chimeric antibodies performed well enough to show promise for therapeutic use.
