Abstract
A quantitative competitive PCR assay for human herpesvirus 6 (HHV-6) was developed. Firstly, viral burden was determined in the blood of 25 healthy persons. Using 1 microgram of DNA, the prevalence of HHV-6 was 36% (9/25). Eight persons had viral loads of < or = 32 HHV-6 genomes/microgram DNA. The viral burden in the ninth individual was 1.2 x 10(6) HHV-6 genome copies/microgram DNA, which remained constant over a period of 10 months. This demonstrates the persistence of a high HHV-6 load in the absence of apparent disease. Secondly, HHV-6 burden was determined in 100 post-mortem tissues from seven AIDS patients and three controls. For all tissues combined, there was a statistically significant higher median viral load in AIDS patients (56 copies/microgram DNA, range 0-43321) compared to controls (10 copies/microgram DNA, range 0-423) (P = 0.04). The precision and reproducibility of this assay will allow hypotheses concerning the pathogenic potential of HHV-6 to be tested quantitatively.Entities:
