Summary
Early recognition and treatment of herpes simplex virus (HSV) meningitis, particularly HSV-2, with intravenous acyclovir (IV ACV) and oral valaciclovir (VACV), leads to rapid symptom resolution and prevents recurrence.
Area of Science:
- Neurology
- Infectious Diseases
- Virology
Background:
- Herpes simplex virus (HSV) meningitis is a rare but serious neurological infection.
- Genital herpes is a common risk factor for HSV meningitis, particularly HSV-2.
Purpose of the Study:
- To retrospectively analyze the clinical characteristics, treatment, and outcomes of 11 patients diagnosed with HSV meningitis.
- To evaluate the efficacy of intravenous acyclovir (IV ACV) and oral valaciclovir (VACV) in managing HSV meningitis and preventing recurrence.
Main Methods:
- Retrospective review of demographic, clinical, and biological data from 11 patients with HSV meningitis.
- Diagnosis confirmed by HSV detection in cerebrospinal fluid (CSF) via PCR, with HSV-2 typing.
- Treatment analysis included IV ACV, oral valaciclovir (VACV), and follow-up for recurrence.
Main Results:
- All 11 patients presented with abrupt onset of severe headache and fever, meningismus, and CSF findings consistent with lymphocytic pleocytosis.
- HSV was detected in CSF in all cases, with HSV-2 identified in 6 patients.
- Rapid symptom resolution (within 48 hours) was observed in all patients treated with IV ACV, with adjunctive oral VACV showing efficacy in preventing recurrence.
Conclusions:
- Early diagnosis and prompt treatment with IV ACV are crucial for favorable outcomes in HSV meningitis.
- Adjunctive oral VACV appears effective in preventing recurrent episodes of HSV meningitis.
- Further studies are needed to establish optimal treatment durations and prophylactic strategies.

Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
Bacterial Meningitis I: Introduction
Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
Herpes
Herpes simplex type 1 (HSV‑1) is a widespread pathogen responsible for orolabial lesions. It is an enveloped, double-stranded DNA (dsDNA) virus belonging to the family Herpesviridae. Once the virus infects a host cell, its double‑stranded DNA genome is delivered into the nucleus, where a coordinated cascade of immediate‑early, early, and late gene expression directs viral DNA replication, structural protein synthesis, and virion assembly. After primary infection of epithelial cells, HSV-1...
Bacterial Meningitis
Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
Genital Herpes
Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...
Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
