[Recurrent lymphocytic meningitis by herpes simplex virus type 2].

Area of Science:

• Neurology
• Infectious Diseases
• Immunology

Background:

• Mollaret's meningitis is a rare recurrent lymphocytic meningitis.
• It stems from diverse causes including infections, autoimmune disorders, toxins, and neoplasms.
• Herpes simplex virus type 2 is the most frequent infectious agent identified.

Observation:

• The condition predominantly affects middle-aged women.
• Clinical presentation is typically self-limited, resolving within a week.
• Patients usually experience no long-term adverse effects or sequelae.

Findings:

• Diagnosis primarily relies on detecting pathogen nucleic acids in cerebrospinal fluid.
• Cerebrospinal fluid analysis is key for identifying the causative agent.
• Antiviral prophylaxis has not demonstrated conclusive efficacy in preventing recurrences.

Implications:

• Further research is needed to understand the pathogenesis of recurrent meningitis.
• Development of targeted therapies to prevent Mollaret's meningitis recurrences is crucial.
• Improved diagnostic strategies may aid in earlier and more accurate patient management.
