AI Article Synopsis

  • The presence of HHV-7 and dual HHV-6A and -6B DNA in the cerebrospinal fluid (CSF) of two patients with facial palsy (FP) raises questions but does not establish a clear cause for the condition.
  • Despite analyzing samples from 33 FP patients and 36 controls, only 10% of tested CSF samples from immunocompetent individuals contained HHV DNA, which is unusual.
  • Further research is needed to understand the significance of these herpesvirus findings and their relationship to FP and other diseases.

Article Abstract

Conclusions: Finding human herpesvirus (HHV)-7 and dual HHV-6A and -6B DNA in cerebrospinal fluid (CSF) of two facial palsy (FP) patients is intriguing but does not allow etiologic conclusions as such. HHV-6 or -7 DNA was revealed in 10% of the CSF samples tested from 70 immunocompetent adolescents and adults; a highly unusual result. How these findings are associated with the diseases they accompany remains to be defined.

Objective: To determine whether herpes simplex virus (HSV)-1 and -2, varicella-zoster virus (VZV), HHV-6A, -6B, and -7, Epstein-Barr virus (EBV), and cytomegalovirus (CMV) DNA could be found in CSF of FP patients or controls.

Subjects And Methods: In all, 33 peripheral FP patients (26 idiopathic, 5 with herpesvirus infection, 1 puerperal, 1 Melkersson-Rosenthal syndrome) (34 CSF samples) and 36 controls (16 nonidiopathic FP, 7 hearing loss, 6 vertigo, 5 headache, 2 other) previously tested for HSV-1, VZV, and HHV-6 DNA by polymerase chain reaction (PCR) were tested with highly sensitive multiplex-PCR and an oligonucleotide microarray method.

Results: One FP patient had HHV-7 DNA and another had HHV-6A and -6B DNA simultaneously. In the control group, one HHV-7, one HHV-6A, and three HHV-6B DNA-positive specimens were found.

Article Synopsis
  • Immune function declines with age, making it difficult to identify individuals at risk for immune-related issues, especially those with reactivated latent viral infections.
  • The study focused on detecting certain human herpes viruses in urine as a potential way to identify immune-compromised individuals, particularly using T cell receptor excision circle (TREC) data as an indicator.
  • While no clear one-to-one correlation was found between TREC values and individual viruses, a significant link was observed for males; specifically, low TREC values correlated with the detection of three or more different herpes viruses, suggesting declining immune function.

Article Synopsis
  • - Human herpesvirus-6B (HHV-6B) reactivation is linked to higher rates of non-relapse mortality (NRM) and overall mortality (OM) in patients undergoing allogeneic hematopoietic stem cell transplants (HCT).
  • - A systematic review and meta-analysis showed a significant association between HHV-6B presence and increased NRM (effect size: 1.84) and OM (effect size: 1.37) after HCT, with NRM results being consistent across studies.
  • - The findings suggest that detecting HHV-6B can be critical for patient outcomes following HCT, highlighting the need for further randomized trials to explore the potential benefits of preventing
