Herpes infections are among the most common sexually transmitted infections (STI), but diagnostic methods for genital herpes have not kept pace with the movement toward molecular testing. Here, we describe an FDA-approved molecular assay that identifies and types herpes simplex virus (HSV) infections for use in routine clinical settings. Paired samples from anogenital lesions were tested using the BD ProbeTec HSV Q(x) (HSVQ(x)) system, HSV culture and, a laboratory-developed PCR assay.

HSV-2, the primary causative agent of genital herpes, establishes latency in sensory ganglia and reactivates causing recurrent lesions and viral shedding. Induction or expansion of CD4(+) and CD8(+) T cell responses are expected to be important for a successful therapeutic vaccine against HSV-2. A candidate vaccine consisting of 32 synthetic 35mer HSV-2 peptides non-covalently complexed with recombinant human Hsc70 protein (named HerpV, formerly AG-707) was tested for safety and immunogenicity in a Phase I study.

Background: Antiviral suppressive therapy of genital herpes is often initiated based on the established pattern of recurrences in an individual. Because most persons with first episode herpes simplex virus type 2 (HSV-2) infection experience recurrences and because viral shedding occurs frequently in the first year after infection, we examined the strategy of initiating suppressive therapy shortly after diagnosis of genital HSV-2 infection.

Subjects And Methods: From June 16, 2004 to July 26, 2006, 384 subjects from 74 sites in the United States, Canada, Argentina, Brazil, and Chile who were newly diagnosed with a first recognized episode of genital herpes at the time of the screening visit or within 3 months before the screening visit were randomized (2:1) to receive valacyclovir 1 g once daily or placebo for 24 weeks.
