Official title
A Phase I Study of the Immune Response to Herpes Simplex Virus Type 1 (HSV-1) and General Immune Health in Subjects Infected With HSV-1
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Subjects were recruited who were positive for antibody against herpes simplex virus type 1 (HSV-1) and self-reported having in the previous 12 months * 6 or more herpes labialis outbreaks (group A), * 1 or 2 outbreaks (group B), or * zero outbreaks (group C). Twelve subjects in each group were recruited. Blood was collected from these persons and peripheral blood mononuclear cells (PBMCs) isolated and tested for proliferation in vitro when stimulated with HSV-1-infected cell extracts, free HSV-1 virus, or Candida albicans extract. Candida albicans is a ubiquitous infectious fungus and its extract is used as a test of general immune response. RNA was also isolated from the PBMCs after incubation in the three stimuli and expression of 41 immune-related genes quantified by quantitative real-time PCR. Also serum anti-HSV-1 IgG levels were quantified. After the blood collection on day 1, the persons in group A (frequent cold sore sufferers) were treated with a single topical application of 2% squaric acid dibutyl ester (SADBE) in DMSO, applied to the inner aspect of the upper arm. These subjects returned on days 15 and 57 for blood collection, and their PBMCs were tested again on those dates for proliferation in vitro against the same stimuli and for gene expression and for serum anti-HSV-1 IgG levels.
