TB Meningitis Risk Factors

High-Risk Populations

• The Centers for Disease Control and Prevention recommends that HIV-infected individuals are at highest risk for TB meningitis at all CD4 counts, with young children under 4 years representing the second major high-risk group due to rapid disease progression and high rates of dissemination, particularly TB meningitis 1, 2
• The World Health Organization notes that patients receiving prolonged corticosteroid therapy are at increased risk for TB disease including meningitis 2
• The American Academy of Pediatrics states that children under 4 years of age are at high risk for rapid development of TB disease, particularly TB meningitis 2
• The Centers for Disease Control and Prevention suggests that alcohol dependency creates relative immunocompromise increasing TB risk 1
• The World Health Organization recommends that travelers returning from TB-endemic areas, particularly those with relevant travel history to high-burden regions, are at increased risk of TB meningitis 1, 5

Clinical Considerations

• The Infectious Diseases Society of America advises that TB meningitis remains an important consideration at all CD4 counts in HIV patients, unlike cryptococcal meningitis which predominantly occurs at CD4 <100 cells/mm³ 1, 3, 4
