Tuberculous meningitis: Challenges in diagnosis and management

Area of Science:

• Neurology
• Infectious Diseases
• Microbiology

Background:

• Tuberculous meningitis (TBM) is a severe form of tuberculosis with high mortality and disability.
• An estimated 100,000 new TBM cases occur annually, with nearly 50% mortality in HIV-1 co-infected patients.
• Current diagnostic methods, like culture, are slow and lack sensitivity, delaying treatment.

Purpose of the Study:

• To highlight the urgent need for rapid and accurate diagnostic tools for TBM.
• To discuss advancements in anti-tuberculosis chemotherapy for TBM.
• To address the challenge of drug-resistant TBM.

Main Methods:

• Review of current diagnostic limitations for TBM.
• Exploration of potential improvements in cerebrospinal fluid (CSF) analysis for diagnosis.
• Analysis of recent clinical trials and pharmacokinetic studies on TBM chemotherapy.

Main Results:

• GeneXpert, while an advance, has insufficient sensitivity for TBM diagnosis.
• Increased CSF volume may enhance diagnostic performance.
• Studies suggest higher rifampicin doses and fluoroquinolones as potential treatment advancements.

Conclusions:

• There is a critical need for novel, rapid, and sensitive diagnostic strategies for TBM.
• Optimizing chemotherapy, including higher drug doses, shows promise but must consider drug resistance.
• Combating drug-resistant TBM remains a significant challenge, demanding urgent attention.
