Objective: Prognosticators of the outcome of patients with cryptococcal meningitis (CM) at variable follow-up time has been reported. We aimed to identify prognosticators of an outcome on hospital discharge of treated CM.
Patients and methods: The presenting characteristics of CM patients admitted in Songklanagarind Hospital from 2002 to 2017 were retrospectively reviewed. The unfavorable outcome was defined as no improvement or death after starting treatment. The significant differences in clinical presentations between the patients with favorable and unfavorable outcomes were descriptively analyzed. The significant independent predictors from the clinical presentations and the first results of cerebrospinal fluid (CSF) analysis with cut-off values were further defined by multiple logistic regression analysis and shown in adjusted odds ratios (p < 0.05).
Results: Sixty-two CM patients were enrolled and 33 (53.2%) of them were females. Their median (IQR) age was 37 (30, 46) years old. HIV serology was positive in 71.0%. Concurrent immunosuppressant use and systemic malignancies were 6.5 and 4.8%, respectively. The median (IQR) days of hospital stay was 18.0 days (12.8, 23.0). Eleven patients had unfavorable outcomes at hospital discharge (8 died, 3 no neurological improvement). Cranial nerve palsy and high CSF protein were dependent predictors for the unfavorable outcome, while high CSF glucose was a protective factor. In addition, CSF protein >270 mg/dL was an independent predictor for the unfavorable outcome when adjusted for other CSF analysis results (adjusted odds ratio 27.1, 95% confidence interval 1.1-678.5, p = 0.034).
Conclusion: Elevated CSF protein was a significant independent predictor for an unfavorable outcome.
