Etiology
- sexually transmitted disease
- Herpes simplex virus (HSV-1, HSV-2)*
- disorders linked to HSV recurrences
- Mollaret's meningitis
- recurrent erythema multiforme
* HSV-1 is usually acquired in childhood via nonsexual contact, & is the primary cause of orolabial herpes but can cause genital herpes
* HSV-2 is usually acquired via sexual contact, uncommonly causes orolabial herpes, but does cause genital herpes[7]
Epidemiology
- transmission of virus occurs most readily when there are active genital lesions
- periods of asymptomatic shedding are associated with most transmission
- in women, asymptomatic shedding greatest in year following primary infection (4.3% of days)
- vertical transmission (to fetus) associated with active lesions or asymptomatic shedding greatest with 1st episode (33-50%), declining subsequently to 3%
- genital HSV-1 shedding frequent after 1st episode genital HSV-1, especially after primary infection, declining within the 1st year, 65% of patients at 2 months, 33% at 11 months[9]
Clinical manifestations
- asymptomatic in 60-90%
- recurrent genital lesions more common with HSV-1 than HSV-2
- painful genital vesicles & erosions
- group vesicles on an erythematous base
- lesions ulcerate when vesicles rupture
- inguinal lymphadenopathy, fever, myalgia, malaise with with primary infection[1]
Laboratory
- Herpes simplex virus DNA most sensitive assay[1]
- viral culture to confirm diagnosis & distinguish HSV-1 from HSV-2
- serologic test for syphilis
- HIV1 serology
- Herpes simplex virus Ab
Management
- daily treatment with acyclovir, famciclovir, or valacyclovir may reduce asymptomatic shedding of virus by 90%, reducing risk of transmission to partner
- treatment indicated for primary infection & severe recurrences
- pharmaceutical agents
- HIV patients may have resistant strains of HSV-2
- increase dose of standard antivirals if not response to usual dose[1]
- foscarnet IV & topical trifluridine
- cidofovir
- resistance testing if no response to high-dose antiviral agent[1]
- recombinant glycoprotein D HSV-2 vaccine may provide prophylaxis against primary infection & recurrences in previously infected individuals
- patient initiated therapy for infrequent recurrences[1]
- suppressive therapy for frequent recurrences (> 5/year)
- reduces symptomatic recurrences
- reduces asymptomatic viral shedding
- reduces risk of transmission of HSV-2 to susceptible partner by ~50%[7]
- offer screening for other sexually-transmitted diseases (see laboratory)[7]
- screening of asymptomatic individuals not recommended[8]
