A group from Washington University used a bioinformatics system called VirusScan to analyze RNA-Seq data sets from 6,813 human tumors compared to those of adjacent normal tissue. Tumor samples representing 23 different forms of cancer were analyzed. HHV-6, EBV and CMV were found at significantly high levels in GI tract cancer tissue.
HHV-6 and EBV elevated in the GI tract of HIV+ patients
A group from Sapienza University in Rome has found a significantly elevated prevalence of HHV-6 and a higher viral load for EBV in the stomach and duodenum biopsies of patients with HIV compared to controls, suggesting that these viruses may contribute to the development of gastric cancer in immunocompromised patients.
Preliminary evidence indicates HHV-6B may be involved in the sporadic development of adenomatous GI Polyps
A group from Finland’s Helsinki University Hospital has published preliminary evidence to suggest HHV-6B may be involved in the development of adenomatous gastrointestinal polyps
HHV-6 & HHV-7 may accelerate disease progression in patients with gastrointestinal cancer
A research team from Riga Stradins University in Latvia has reported that the activation of HHV-6B and HHV-7 in patients with gastrointestinal cancer may lead to a marked decrease in lymphocytes and worsening of immunosuppression.
