To evaluate the efficacy and safety of ABCD in the treatment of cryptococcal meningitis in non-HIV patients at week 4, the end of induction therapy, week 10 and the end of consolidation therapy.
This study is a multi-center, single-arm clinical study. The objective is to evaluate the efficacy and safety of ABCD in the treatment of cryptococcal meningitis in non-HIV patients. Qualified subjects shall receive cryptococcus induction therapy with ABCD combined with flucytosine for at least 4 weeks, or termination of treatment early at the investigator's discretion. Efficacy and safety are followed up at week 4 (day 28), the end of induction therapy, week 10 (day 70) and the end of consolidation therapy.

Proportion of patients with complete or partial response at the end of induction therapy
Complete response: live during the observation period, patients with cryptococcus meningitis all the clinical signs and symptoms disappeared, a significant reduction in the cerebrospinal fluid cryptococcal antigen test results and/or CSF cryptococcus training and/or ink staining (two consecutive tests, one week interval) results overcast, and abnormal head MRI/CT (if exist in baseline) improved or stable. Partial response: patient survival during the observation period, cryptococcal meningitis clinical signs and symptoms improved, all the significant reduction in the cerebrospinal fluid cryptococcal antigen test results and/or CSF cryptococcus training and/or ink staining (two consecutive tests, one week interval) results overcast, and abnormal head MRI/CT (if exist in baseline) improved or stable.
Time frame: From enrollment to the end of induction therapy (about 4-6 weeks)
