HSV meningitis is meningitis associated with a herpes simplex virus (HSV) infection.[1]
HSV is a common cause of viral meningitis, with HSV-2 the second most common cause of meningitis in adults.[2] HSV-1 can also cause meningitis.[3] HSV meningitis can occur either with the initial symptoms of a herpes infection or later upon re-activation of a prior infection.[4]
Clinical presentation
[edit]Common symptoms include nausea, vomiting, neck-stiffness, photophobia, and severe frontal headaches.[2] Patients with meningitis secondary to the HSV-2 virus may also present with genital lesions, although most cases of HSV-2 meningitis occur without symptoms of genital herpes.[5][6] Around one fifth of people infected with HSV-2 have symptoms of meningitis with their initial infection, more commonly men than women.[7]
Diagnosis
[edit]HSV meningitis can be diagnosed through a spinal tap, and PCR analysis of the cerberospinal fluid for HSV DNA. Not everyone with an HSV infection and meningitis tests positive for HSV DNA in the cerebrospinal fluid.[8]
Treatment
[edit]HSV meningitis often spontaneously recovers.[9] Treatment is usually supportive with the antivirals acyclovir and valacyclovir sometimes given.[1]
Incidence
[edit]Herpes is a common cause of viral meningitis, with around one in twenty viral meningitis cases caused by a herpes simplex virus.[10] HSV-2 is the most common cause of meningitis in adults[1]. Herpesviral meningitis primarily affects people aged 35-40, the elderly, and women.[11]
Recurrent Herpesviral meningitis
[edit]Herpesviral meningitis can sometimes be recurring, with HSV-2 causing most cases of recurrent benign lymphatic meningitis.[4] Deficient T-cell immunity can make someone more prone to recurrent meningitis.[4]
Mollaret's meningitis, a specific type of recurrent meningitis first described in 1944, has since been found to be most commonly caused by HSV-2.[12][1]
Mollaret's Meningitis
[edit]HSV-2 is the most common cause of Mollaret's meningitis, a type of recurrent viral meningitis.[1] This condition was first described in 1944 by French neurologist Pierre Mollaret. Recurrences usually last a few days or a few weeks, and resolve without treatment. They may recur weekly or monthly for approximately 5 years following primary infection.[13]
