Immunological studies of cerebrospinal fluid from patients with CNS symptoms after human papillomavirus vaccination

Highlights

  • 32 patients with prolonged CNS symptoms after HPV vaccination were studied.
  • CSF levels of IL-4, IL-13, IL-17, IL-8 and MCP-1 were elevated.
  • CSF levels of PDGF-bb and IL-12 were decreased.
  • Antibodies to GluN2B-NT2, GluN2B-CT and GluN1-NT in CSF were increased.

Abstract

In 32 patients with prolonged central nervous system symptoms after human papillomavirus (HPV) vaccination, we measured conventional and immunological markers in cerebrospinal fluid (CSF) and compared with the levels in disease controls. Our studies revealed significantly decreased chloride and neuron-specific enolase (NSE) levels in CSF of patients with CNS symptoms after HPV vaccination compared to disease controls. IL-4, IL-13, and CD4+ T cells increased significantly in patients, and IL-17 increased significantly from 12 to 24 months after symptom onset. Chemokines (IL-8 and MCP-1) were also elevated, but CD8+ T cells, PDGF-bb and IL-12 were reduced. Antibodies to GluN2B-NT2, GluN2B-CT and GluN1-NT increased significantly. These results suggest biological, mainly immunological, changes in the CSF of patients after HPV vaccination.

  1. Have you looked at the price of Immunological Journal articles? It around $35 per article. I used to find more for free on the US CDC website – now all are charged. Really upsetting when you are trying to find key things to ask doctors to measure for your child – and you are a lay person.

    • We run into that problem all the time – medical/scientific studies should not be hidden behind a paywall. They should be open access for all to see.
