Cryptococcal meningoencephalitis is a systemic fungal infection in immunocompromised and immunocompetent individuals. This study investigated the clinical characteristics and factors associated with mortality in HIV-associated and non-HIV-associated cryptococcal meningoencephalitis in a resource-limited setting. This was a retrospective cohort study of patients with cryptococcal meningoencephalitis between January 2009 and December 2019 at a tertiary teaching hospital in Thailand. Overall, 1019 patients with cryptococcal meningoencephalitis were enrolled, and 923 (90.6%) were HIV-positive. The patients with HIV-associated cryptococcal meningoencephalitis were younger than the HIV-negative patients (37 versus 56 years, p < 0.01). The HIV-negative patients were more likely to have underlying conditions (52.1% versus 7.5%; p < 0.01), had a longer median duration of headaches prior to admission (14 days versus 6 days, p < 0.01), and were more likely to have an altered mental status at presentation (36.5% versus 18.6%, p < 0.01) and pulmonary involvement (15.6% versus 0.8%, p < 0.01). The HIV-positive patients had lower cerebrospinal fluid (CSF) white blood cell counts (4 versus 94 cells/mm3; p < 0.01), lower CSF protein (69 versus 157 mg/dL; p < 0.01), higher CSF glucose (38.8 versus 21 mg/dL; p < 0.01), and more frequent cryptococcemia (44.1% versus 20.5%; p < 0.01). The mortality rate was high but not significantly different between the two groups (30.2% versus 33.2%; p = 0.53). The HIV-positive patients with comorbidities, fever, an altered mental status at presentation, a CSF white blood cell count below 20 cell/mm3, fungemia, and positive CSF India ink were independently associated with 30-day mortality. In comparison, an altered mental status at presentation and fungemia were associated with 30-day mortality in HIV-negative patients. In conclusion, HIV-negative patients with cryptococcal meningoencephalitis had more extensive central nervous system inflammation, although the two groups’ mortality rates were similar. Unfavorable prognostic factors included comorbidities, fever, an altered mental status at presentation, a low CSF white blood cell count, fungemia, and positive CSF India ink. |
