HIV Infection Does Not Increase 10-Week Mortality of Chinese Cryptococcal Meningitis Patients.

The role of HIV infection in precipitating different clinical features in cryptococcal meningitis (CM) patients remains controversial. One hundred twelve CM patients living with HIV/AIDS (CM+HIV+ patients) and 112 CM patients living without HIV/AIDS (CM+HIV- patients) were enrolled after propensity score matching. Demographic characteristics, symptoms, routine blood tests, and biochemical and cerebrospinal fluid (CSF) profiles were compared between the two groups. Kaplan-Meier analysis and Cox proportional hazards model was used to assess 10-week mortality. CM+HIV+ patients frequently occurred in young (mean age 40.3 ± 10.5) and male (89.3%) populations who also experienced leukopenia, neutropenia, lymphocytopenia, thrombocytopenia, and hypoalbuminemia, less headaches (66.9%), and higher cryptococcemia (23.2%) (all  < .050); they also had higher glucose (2.6 ± 1.1 mmol/L), increased smear positivity (78.8%), and decreased white blood cells [8.0 (2.0-28.0) × 10/L] in initial CSF assay (all  < .050). The 10-week cumulative survival rate was 84.6% for CM+HIV+ patients and 88.5% for CM+HIV- patients ( = .345). Age <35.0 years (hazard ratio (HR) 3.0 (1.0-8.9),  = .046), intracranial pressure (ICP) >250.0 mmHO (HR: 4.8 (1.1-21.6),  = .041), and treatment lacking amphotericin B [HR: 6.5 (1.9-21.4),  = .003] were independent risk factors for 10-week mortality in CM+HIV+ patients. There are significant clinical differences in CM patients living with or without HIV/AIDS. However, the 10-week survival rate was similar between the two groups. Younger population, high ICP, and treatment lacking amphotericin B were independent risk factors for 10-week mortality of Chinese CM+HIV+ patients.
