Abstract

Six immunocompetent patients with human herpesvirus 6 (HHV-6) chromosomal integration had HHV-6 and β-globin DNA quantified in various samples by PCR. The mean HHV-6 DNA concentration (log10 copies/milliliter) in blood was 7.0 (≥1 HHV-6 DNA copies/leukocyte), and in serum it was 5.3 (≥1 HHV-6 DNA copies/lysed cell). The mean HHV-6 DNA load (log10 copies)/hair follicle was 4.2 (≥1 copies/hair follicle cell), demonstrating that viral integration is not confined to blood cells. The characteristically high HHV-6 DNA levels in chromosomal integration may confound laboratory diagnosis of HHV-6 infection and should be given due consideration.
