Abstract

To investigate the mortality of HIV infected clients from methadone maintenance treatment (MMT) clinics in Yili Kazakh autonomous prefecture as well as the factors associated with mortality of HIV infected clients. A retrospective cohort study was performed. Data of 860 cases were collected from National Methadone Maintenance Treatment database, National AIDS/HIV database and antiretroviral therapy (ART) treatment database for adults. Information collected included demographic information of HIV infected clients, methadone daily treatment information, CD4 testing information, ART treatment information and death information. Recruiting began from August, 2005 through May, 2011. Cox proportional regression was used to identify factors associated with mortality. The proportional hazard assumption was assessed using Schoenfeld's residuals test. Missing values were imputed using the multiple linear regression method. R software (version 2.13.0) was used to perform data analysis. A total of 860 HIV positive MMT clients were analyzed. The methadone dose for study subjects was (38.2 ± 20.7) mg/d. 27.8% (239/860) of study subjects participated in ART treatment, 38.7% (333/860) had never tested for CD4 count. The age for study subjects was (32.9 ± 6.4) years old. Among all these subjects, 67.3% (579/860) were married. During the observation period, 151 deaths were observed in 2192.9 person years. The average observation time was 2.6 year for each subject. The all-cause mortality rate was 68.9‰. Cox proportion model showed that ART treatment (HR = 0.53, 95%CI: 0.32 - 0.88), baseline CD4 count at 200 - 350 cells/μl (HR = 0.35, 95%CI: 0.20 - 0.60), baseline CD4 count more than 350 cells/μl (HR = 0.16, 95%CI: 0.09 - 0.29), and marriage (HR = 0.55, 95%CI: 0.37 - 0.82) were associated with less mortality compared with control group. Age (more than 45 years old) (HR = 5.20, 95%CI: 2.60 - 10.20) and sharing needles (HR = 1.40, 95%CI: 1.02 - 2.00) were risk factors associated with death. High mortality rate was observed among HIV infected clients. Methadone clinic should provide ART treatment or ART referral services.
