Abstract:
Objective To understand the predictors and prognostic significance of cranial nerve impairment in non-acquired immune deficiency syndrome (AIDS) patients with cryptococcal meningitis.Methods A total of 145 non-AIDS patients with cryptococcal meningitis admitted to Huashan Hospital,Fudan University from Jan 2000 to Dec 2010 were reviewed retrospectively.Clinical characteristics,initial antifungal therapies and outcome of these patients were analyzed.Continuous variables were analyzed using t test and categorical variables were compared by x2 test or Fisher's exact test.Multivariate analysis was performed by binary Logistic regressions.Results Out of 145 patients,52 (35.9％) patients had cranial nerve impairment at enrollment.Optic (25/52,48.1％) and oculomotor (22/52,42.3％) nerves were the most commonly involved,followed by auditory (12/52,23.1％),abducens (6/52,11.5％),olfactory (4/52,7.7％) and facial (3/52,5.8％) nerves.The best predictive factor of cranial nerve injury was duration of diagnosis (OR =1.056,95％ CI:1.002-1.111).The risk of cranial injury would increase by 5.6％ with one-week delay of diagnosis.Intracranial hypertension and low cerebrospinal fluid cell count were also the independent predictive factors (both P＜0.05).In the follow-up period,73.3％ patients who had cranial nerve injuries were fully recovered,with a median time of 3 (0.5-24.0) months.The independent predictors of recovery were numbers of nerve involved (OR =0.230,95 ％ CI:0.066-0.800,P=0.021) and amphotericin B (AmB) plus 5-fluorocytosine,triazole antifungal agent therapy (OR=10.317,95％CI:2.086-51.025,P=0.004).Conclusions Cranial nerve impairment occurs in one-third of non-AIDS patients with cryptococcal meningitis.Delay in diagnosis,intracranial hypertension and low cerebrospinal fluid cell count are independent predictive factors.Less cranial nerve involvement and AmB plus triazole therapy predict recovery.
