HHV-6 is an opportunistic viral pathogen that has been demonstrated as the cause of often life-threatening illness in pediatric patients and transplant recipients. A substantial body of scientific evidence links HHV-6 to the etiology of such chronic diseases as multiple sclerosis. For these reasons, it is important that patients in these groups be screened for possible infection with HHV-6. Serological studies for IgG and/or IgM can be misleading, as are PCR analyses, which cannot distinguish between latent and actively replicating virus. Currently, the only reliable method for diagnosing an active infection with HHV-6 is viral isolation.

D015654 Herpesvirus 6, Human Members of the ROSEOLOVIRUS genus of the Betaherpesvirales subfamily isolated from patients with AIDS and other LYMPHOPROLIFERATIVE DISORDERS. It infects and replicates in fresh and established lines of hematopoietic cells and cells of neural origin. It also appears to alter the activity of NK CELLS. HHV-6; (HBLV) antibodies are elevated in patients with AIDS; SJOGREN'S SYNDROME; SARCOIDOSIS; CHRONIC FATIGUE SYNDROME, and certain malignancies. HHV-6A is the most common cause of EXANTHEMA SUBITUM and has been implicated in encephalitis. When HHV-6 integrates into the host genome it is referred to as ciHVH-6. When such VIRUS INTEGRATION occurs into the germline it is referred to as iciHHV-6.

D016133 Polymerase Chain Reaction In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.
