Abstract
BACKGROUND: Cryptococcal meningitis (CM) is the most common fungal infection of the central nervous system and has high morbidity and mortality. Almost studies about prognostic factors have largely focused on the immunocompromised population rather than immunocompetent patients. So that we sought to conduct a retrospective study to determine prognostic factors which predict the outcomes in immunocompetent patients with CM. METHODS: We retrospectively collected and analyzed the demographic and clinical data of 76 apparently immunocompetent patients with cryptococcal meningitis from January 2003 to June 2019 in China. The clinical outcome was graded by the Glasgow outcome scale (GOS) at discharge, and patients were divided into good (score of 5) and unfavorable (score of 1-4) outcome groups, potential prognostic factors were analyzed. RESULTS: Non-parametric test confirmed that unfavorable outcome was associated with lower glucose level of CSF(P = 0.001), and Pearson's χ2 analysis confirmed that unfavorable outcome was associated with opening pressure of CSF(>300mmH20, P = 0.038), impaired consciousness (P = 0.001), hydrocephalus(P = 0.045), and Shunt surgery (P = 0.045), and then multiple logistic regression analysis confirmed that impaired consciousness(P = 0.015) and lower glucose concentration of CSF(P = 0.012) increased the likelihood of unfavorable outcome in CM patients. CONCLUSION: Impaired consciousness and decreased glucose concentration of CSF were independently prognostic factors which predict the unsatisfactory outcome in immunocompetent patients with CM.
