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.

EBV and HHV-6B but no CMV found in astrocytomas by digital droplet PCR

In All, Cancer, CNS Disease, Latest Scientific News by Kristin Loomis

A group from the National Institute of Neurological Disorders and Stroke, NIH, has reported finding Epstein-Barr Virus (EBV) and HHV-6 but no cytomegalovirus (CMV) in astrocytomas, a brain tumor comprising approximately one quarter of all gliomas diagnosed. The group used digital droplet PCR (ddPCR), a technique that is highly precise but less sensitive than nested PCR and immunohistochemistry, techniques that have been used in previous studies.
