摘　　要：Background Amphotericin B （0.7 mg/kg） with flucytosine is the standard treatment for cryptococcal meningitis.However,the long treatment course can induce adverse reactions in patients; therefore,reducing the dose may decrease such reactions.We performed a retrospective analysis of treatment effects and adverse reactions when amphotericin B （0.4 mg/kg or 0.7 mg/kg per day） and flucytosine were used together to treat HIV-negative patients with cryptococcal meningitis.Methods Retrospective analysis was conducted on inpatients at the First Affiliated Hospital,College of Medicine,Zhejiang University （January 2005 to December 2009）.Low- or high-dose amphotericin B （0.4 or 0.7 mg/kg per day,respectively） plus flucytosine was used.The negative conversion rate of Cryptococcus in the cerebrospinal fluid （CSF）,patient mortality,and the incidence of side effects for the two groups （low- vs.high-dose） were compared immediately after treatment and 2 and 10 weeks later.Data were analyzed by the Student＇s t test,chi-square tests using SPSS 12.0 statistical soitware.Results Two weeks post-treatment,Cryptococcus negative CSF rates were 78% （18/23） in the low-dose group and 87% （13/15） in the high-dose group （P=0.28）.Ten weeks post-treatment,both groups were negative.The mortality rate was 8% （2/25） in the low-dose group and 17% （3/18） in the high-dose group （P=-0.25）.There was a statistically significant difference in the incidence of adverse events between the groups,48% （12/25） and 78% （14/18） in the low- and high-dose groups,respectively （P=0.04）.Adverse events that required a change in treatment program in the low-dose group were 12% （3/25） compared to 39% （7/18） in the high-dose group （P=-0.04）.Conclusion Low-dose treatment regimens were better toleratedBackground Amphotericin B （0.7 mg/kg） with flucytosine is the standard treatment for cryptococcal meningitis.However,the long treatment course can induce adverse reactions in patients; therefore,reducing the dose may decrease such reactions.We performed a retrospective analysis of treatment effects and adverse reactions when amphotericin B （0.4 mg/kg or 0.7 mg/kg per day） and flucytosine were used together to treat HIV-negative patients with cryptococcal meningitis.Methods Retrospective analysis was conducted on inpatients at the First Affiliated Hospital,College of Medicine,Zhejiang University （January 2005 to December 2009）.Low- or high-dose amphotericin B （0.4 or 0.7 mg/kg per day,respectively） plus flucytosine was used.The negative conversion rate of Cryptococcus in the cerebrospinal fluid （CSF）,patient mortality,and the incidence of side effects for the two groups （low- vs.high-dose） were compared immediately after treatment and 2 and 10 weeks later.Data were analyzed by the Student＇s t test,chi-square tests using SPSS 12.0 statistical soitware.Results Two weeks post-treatment,Cryptococcus negative CSF rates were 78% （18/23） in the low-dose group and 87% （13/15） in the high-dose group （P=0.28）.Ten weeks post-treatment,both groups were negative.The mortality rate was 8% （2/25） in the low-dose group and 17% （3/18） in the high-dose group （P=-0.25）.There was a statistically significant difference in the incidence of adverse events between the groups,48% （12/25） and 78% （14/18） in the low- and high-dose groups,respectively （P=0.04）.Adverse events that required a change in treatment program in the low-dose group were 12% （3/25） compared to 39% （7/18） in the high-dose group （P=-0.04）.Conclusion Low-dose treatment regimens were better tolerated
