Causation Human Herpesvirus 6

Human herpesvirus 6 (HHV-6) was the sixth herpesvirus discovered. Isolated cases of pulmonary failure in immunocompetent patients have been attributed to HHV-6 when no other pathogens have been isolated; however, such cases are not common, and no causal relation has been established. Human herpesvirus 6 (HHV-6) is the common collective name for Human herpesvirus 6A (HHV-6A) and Human herpesvirus 6B (HHV-6B). These closely related viruses are two of the nine herpesviruses known to have humans as their primary host.

ABSTRACT A virus was isolated from the peripheral blood lymphocytes of patients with exanthem subitum, cultured successfully in cord blood lymphocytes, and shown to be antigenically related to human herpesvirus-6 (HHV-6).

Of importance, the detection of virus does not prove causation. Like most human herpesviruses, HHV-6 is ubiquitous and capable of establishing a lifelong, latent infection of its host. Human herpesvirus 6 (HHV-6) , the causal agent of roseola infantum, infects almost all children by 2 years of age 1. HHV-6 subsequently latently infects PBMCs, salivary glands, and brain tissue 1.

To confirm the causal nature of human herpes virus type 6 (HHV-6) for exanthema subitum we could demonstrate eight seroconversions testing sera from 14 patients with roseola infantum. Human herpesvirus 6 (HHV-6) DNA levels in peripheral blood mononuclear cells were prospectively evaluated in 20 cytomegalovirus-seronegative allogeneic marrow transplant patients and in 10 healthy control subjects.

Disease associations rather than causation in HHV-6 and 7 infected patients make the interpretation of case reports of successful therapy problematic.

Although the isolation of human herpesvirus 6 (HHV-6) was not attempted, positive IgM antibody to HHV-6 was detected in the patient’s serum.

Cross-reactivity between human herpesvirus 6 (HHV-6) and human herpesvirus 7 (HHV-7) antibodies and the reliability of specific serological assays were analyzed for 12 patients with concurrent HHV-6 and HHV-7 antibody responses after transplantation with a liver from a living relative by using an immunofluorescence assay (IFA). A total of 9 of 12 patients demonstrated concurrent HHV-6 and HHV-7 antibody responses, including increased IgG titers andor the presence of IgM by IFA, and were thus analyzed for cross-reactive antibody to heterologous virus.

This evidence is provocative but not definitive, and it does not distinguish between HHV-6 as a causal agent in MS versus HHV-6 as a cofactor.
