Abstract

Abstract: Background: Cryptococcal meningitis (CM) is a life-threatening condition that requires prompt recognition and management. With high morbidity in mind, we elected to compare the key CSF analysis, blood culture and serum cryptococcal antigen (CrAg) to prognosticate the probability of mortality in this population. Table 1. Comparison of demographics, serum and CSF analysis Methods: We retrospectively reviewed all charts of patients admitted to our tertiary care center from 10/2005 to 10/2017. Inclusion criteria encompassed patients with positive CSF CrAg, positive CSF cultures, India ink, cytopathology, or CSF cell count >5 with CNS symptoms, positive serum CrAg titer or blood cultures. Results: Sixty patients who met the inclusion criteria were divided into the survivor (n=41) and the non-survivor (n=19) groups based on the inpatient mortality. There was no difference in age, sex, and immune status between the two groups. The median CSF nucleated cell counts in the non-survivor group was 39 cells/µL with median lymphocyte 59.5% whereas in the survivor group was 72 cells/µL with median lymphocyte 76% (P< 0.001 and 0.04 respectively). The median CSF glucose was 27 mg/ml in the non-survivor compared to 35 mg/ml in the survivor group (P=0.02). Median CSF CrAg was higher at 1:1024 in the non-survivor group whereas the survivor group was 1:256 (P < 0.01). CSF opening pressure (cm H2 O), blood culture, and serum CrAg level were not statistically significant between the two groups. Conclusion: Low CSF cell count, low glucose, and high CSF CrAg were independently associated with inpatient mortality in CM. This is in line with the prior findings. A novel finding in this study is significantly decreased median CSF lymphocyte % in the non-survivor group. Serum CrAg titer, positive blood cultures, and median CSF protein were not statistically significant between the two groups. However, a study with a larger sample size may be needed to confirm these findings. Disclosures: All Authors : No reported disclosures
