Summary
Long-term survival for tuberculous meningitis patients receiving modern chemotherapy is poor. This study found significantly lower survival rates in proven tuberculous meningitis cases compared to controls, highlighting an urgent need for new treatment strategies.
Area of Science:
- Neurology
- Infectious Diseases
- Public Health
Background:
- Long-term outcomes for tuberculous meningitis (TBM) patients treated with modern chemotherapy remain unclear.
- Tuberculous meningitis poses a significant global health challenge, particularly in resource-limited settings.
Purpose of the Study:
- To determine the long-term survival rates of patients with proven tuberculous meningitis.
- To compare survival outcomes between microbiologically proven TBM cases and controls meeting CDC criteria for non-proven TBM.
Main Methods:
- Retrospective case-control study of TBM patients diagnosed and treated in Texas between 2000 and 2005.
- Cases: microbiologically proven TBM. Controls: Mycobacterium tuberculosis not isolated but met CDC criteria for non-proven TBM.
- Average observation periods: 3.76 years for cases and 4.51 years for controls.
Main Results:
- Survival rate at the end of the observation period was 39.76% for proven TBM cases.
- Survival rate was significantly higher in controls at 85.07%.
- Directly observed therapy was used for treatment in this cohort.
Conclusions:
- The long-term outlook for patients with proven tuberculous meningitis treated with current standard therapy is bleak.
- Current treatment strategies for tuberculous meningitis require urgent re-evaluation.
- Further research into novel therapeutic approaches is essential to improve patient survival.

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...

01:27Cryptococcal 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,...
01:22Bacterial 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...
01:23Tuberculosis
Tuberculosis (TB) remains a significant global health concern, primarily targeting the lungs and spreading through airborne transmission. Infection begins when aerosolized droplet nuclei, expelled by an individual with active TB, are inhaled by another person. These microscopic particles carry Mycobacterium tuberculosis, the causative agent of TB. Upon reaching the alveoli, the bacilli are engulfed by alveolar macrophages. However, due to their specialized lipid-rich cell wall, these pathogens...
01:31Pulmonary Tuberculosis III
Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
