[Trimethoprim-sulphamethoxazole-induced meningitis]
Abstract:
Drug-induced meningitis is rarely included in the differential diagnosis of aseptic (usually recurrent) meningitis. A 74-year-old man who suffered from recurrent aseptic meningitis following re-exposures to trimethoprim-sulphamethoxazole (Resprim) is presented. The clinical and laboratory findings resembled those found in bacterial meningitis, excluding normal glycorrachia. Extensive microbiological, serologic and imaging studies did not disclose any relevant findings. All symptoms and signs resolved rapidly following drug withdrawal, and findings on follow-up lumbar puncture were normal.
Insights
Recurrent aseptic meningitis can be caused by trimethoprim-sulphamethoxazole. Prompt drug withdrawal led to rapid symptom resolution, highlighting the importance of considering drug-induced meningitis in differential diagnoses.
Area of Science:
- Neurology
- Pharmacology
- Infectious Diseases
Background:
- Aseptic meningitis is often recurrent and challenging to diagnose.
- Drug-induced meningitis is infrequently considered in the differential diagnosis.
- Trimethoprim-sulphamethoxazole is a common antibiotic with potential adverse effects.
Observation:
- A 74-year-old male presented with recurrent aseptic meningitis.
- Symptoms mimicked bacterial meningitis, except for normal cerebrospinal fluid glucose.
- Recurrence was linked to re-exposure to trimethoprim-sulphamethoxazole (Resprim).
Findings:
- Extensive investigations including microbiological, serologic, and imaging studies were negative.
- Cessation of trimethoprim-sulphamethoxazole resulted in rapid and complete resolution of symptoms.
- Follow-up lumbar puncture confirmed normalization of cerebrospinal fluid parameters.
Implications:
- Drug-induced meningitis should be considered in cases of recurrent aseptic meningitis.
- Identifying and withdrawing the causative drug is crucial for patient recovery.
- This case underscores the importance of a thorough drug history in meningitis workups.
