Abstract:
Objectives To investigate the clinical features,prognosis and risk factors of patients with cryptococcal meningitis.Methods Totally 146 patients with cryptococcal meningitis who were hospitalized in Huashan Hospital from January 2000 to December 2006 were enrolled in this study.The clinical data including diagnosis and misdiagnosis,experimental and etiology tests,treat- ments and prognosis from all the patients were analyzed retrospectively.Results Among the 146 patients enrolled in the study,78 patients(53.4%)had concomitant diseases.The misdiagnosis rate of all patients was 72.6%(106/146).The positive rate of cerebrospinal fluid(CSF)India ink smear was 59.6%(87/106),while 43.2%(63/146)cases of cryptococcus neoformans culture in CSF was positive.The positive rate of Latex agglutination test(LAT)was 91.7%(134/146)in CSF among all patients.The treatments were as follows:combination of Amphotericin B(AmpB)or its lipid formula- tions with flucytosine(5-FC)(98 cases),including combination with Fluconazole initally(62 cases), single therapy of Fluconazole(13 cases).Ommaya implanted for lateral cerebral ventricle drainage(53 cases)and AmpB intrathecal injection(53 cases).The average dose of AmpB is 3.06 g.The course of treatment lasted from 12 weeks to 20 months.There were 104 patients(71.2%)cured,27(18.5%) improved,15(10.3%)died and 34(23.3%)relapsed.Conclusions High misdiagnosis rate is common in patients with cryptococcal meningitis.Immunodeficiency is the major risk factor for cryp- tococcal meningitis.CSF LAT is the most sensitive diagnostic test.Early diagnosis,combination of AmpB with 5-FC antifungal therapy and control of acute intracranial hypertension are the keys to im- prove prognosis of cryptococcal meningitis.
