In All, CNS Dysfunction, Encephalitis & Encephalopathy, Transplant Complications by Kristin Loomis

A young woman on rituximab and two other immunomodulatory agents for the treatment of dermatomyositis developed encephalitis with severe anterograde amnesia. As the use of biologic treatments for refractory autoimmune disease has been increasing, physicians are advised to consider HHV-6 and offer prompt antiviral therapy to limit irreversible morbidity.

Does the high level of U94 in iciHHV-6 contribute to abnormal ‘marker’ chromosomes and cancer?

In All, Cancer, ciHHV-6 by Kristin Loomis

Investigators from the University of Ferrara, Italy have found evidence suggesting that high levels of U94 in ciHHV6 may predispose to the formation of marker chromosomes. A patient with diffuse large B-cell lymphoma positive for inherited chromosomally integrated HHV-6A and HHV-6A was also found in a marker chromosome, an abnormal piece of chromosome that is seen in some leukemia and lymphomas.

Announcing the new “Dharam Ablashi Research Fund”

In All by Kristin Loomis

The HHV-6 Foundation is pleased to announce the creation of a new $250,000 research fund to honor the work Dharam Ablashi, the co-discoverer of HHV-6. The gift was made possible by a generous donation from a patient family in appreciation of Dharam’s outstanding service to the field of HHV-6 research over four decades. The funds will be used to offer pilot grants of up to $25,000 each to investigators seeking to gather preliminary data before embarking on larger studies.

HHV-6 identified in 12% of simple and 42% of complex pediatric febrile seizures

In All, CNS Disease, CNS Dysfunction, Epilepsy and Seizures by Kristin Loomis

Australian investigators studied 143 young children with febrile seizures for signs of viral infection and found that HHV-6 was the fifth most common virus after rhinovirus (22%), enterovirus (20%), adenovirus (21%) and influenza (13%). Overall, a virus was found in 71% of cases. Virus found in complex seizures was associated with HHV-6 (42%) or influenza (41%).

HHV-6, HHV-7 & EBV found in lymphoproliferative disorders of the ocular adnexa

In All, Cancer by Kristin Loomis

Biopsies from patients with 5 types of lymphoproliferative disorders of the ocular adnexa, were found to contain HHV-6 DNA in 9 of 70 (12.9%) samples. While an overall detection rate of 12.9% is significant, HHV-6 was even more prevalent among those with benign lymphoproliferative disorders; HHV-6 was found in 22.7% of those with IgG4-related ophthalmic disease and 28.6% of those with orbital reactive lymphoid hyperplasia.
