HHV-6A was the most common virus identified, but was not linked to worse outcomes compared to other viral infections.
Investigators from the Children’s Hospital of Mexico found that although CMV caused the biggest increase in risk for liver rejection, HHV-6 was the more important infection associated with rejection of kidney transplants. A single HHV-6 infection resulted in an increased risk of over 5 fold, while a coinfection of EBV, HHV-6 and HHV-7 increased the risk of kidney rejection by over 17 fold.
A new case study suggests that HHV-6 might play a role in the multi-organ failure that often follows extreme cases of drug hypersensitivity. Although there have been many studies documenting HHV-6 viremia in drug hypersensitivity (DIHS/DRESS) cases, this is the first to examine an affected organ for signs of HHV-6 DNA and proteins. The mortality rate from severe drug hypersensitivity …
A new study from Brazil indicates that active HHV-6 infection may play a role in patients with renal failure prior to transplantation.
