Detection of HHV-8 Antibodies in Hematopoietic Stem Cell Transplant Recipients

Strategic Insights

— 1 min read

A new study from Canada has found that human herpesvirus 8 (HHV-8) specific antibodies are detectable in hematopoietic stem cell transplant recipients using a peptide-based enzyme immunoassay. The study, published in the Journal of Clinical Microbiology, evaluated the seroprevalence of HHV-8 in 42 allogeneic SCT recipients from Canada and found that HHV-8 specific antibodies were detected in 12% of the patients. The study's findings emphasize the need for prospective studies to determine the source of HHV-8 infection in SCT recipients.

Key Takeaways:

  • The study found that HHV-8 specific antibodies were detectable in 12% of hematopoietic stem cell transplant recipients using a peptide-based enzyme immunoassay.
  • The peptides used in the study were found to be effective in detecting HHV-8 specific antibodies, with all positive results confirmed by at least one of the immunofluorescence assays.
  • The study found no association between HHV-8 seropositivity and clinical or laboratory abnormalities, and no sustained viremia was detected in the seropositive patients.
  • The study highlights the need for prospective studies to determine the source of HHV-8 infection in SCT recipients.
  • The study's findings have implications for the diagnosis and monitoring of HHV-8 infection in immunocompromised patients.

Statistics:

  • 12% of hematopoietic stem cell transplant recipients (42 patients) were found to have HHV-8 specific antibodies detected using a peptide-based enzyme immunoassay.
  • The peptides used in the study were found to be effective in detecting HHV-8 specific antibodies in 5 patients, with all positive results confirmed by at least one of the immunofluorescence assays.
  • 2% of the patients were seropositive for HHV-8 specific antibodies before transplantation.
  • 5 patients showed seroconversion or reactivation between days 21 and 91 post-transplantation.
  • No HHV-8 DNA was detected by real-time PCR in the corresponding leukocytes and plasma of the seropositive patients.
