Cryptococcus Neoformans Meningitis Cases Among China's HIV-Infected Population may have been Severely Under-Reported.

Cryptococcal meningitis (CM) is the leading fungal infection of the central nervous system. Globally, most CM cases have been reported from patients with compromised immunities, especially those infected with HIV. However, reports from China have shown that most CM infections were from HIV-negative, immunocompetent hosts. Here, we reviewed the published reports and found those studies were almost exclusively based on patients from hospitals associated with Chinese universities but not from specialized infectious diseases hospitals where most Chinese HIV-infected patients have been treated. Thus, we believe CM cases among China's HIV-infected population may have been severely under-reported. Analyses of CM cases in specialized infectious diseases hospitals are needed to identify the true epidemiological pattern of CM in China.
