HHV-6 is a greater risk than CMV for rejection in pediatric kidney transplantation

In All, Kidney Disease, Transplant Complications by Kristin Loomis

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.

HHV-6 induced kidney damage in drug hypersensitivity

In Drug Hypersensitivity, Kidney Disease by hhv6foundation

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 is approximately 10%, and death usually results from a late flare in symptoms and failure of one or more organ, typically the liver, kidney, lungs or heart. HHV-6 viremia occurs in the majority of extreme drug hypersensitivity cases (Pritchett 2012) but the reason for the disproportionate reactivation of HHV-6 is not understood. The case, which is presented by a Japanese …
