Eligible studies regarding plasma Hcy level in HIV-infected patients were firstly identified. After careful analysis by two independent researches, the identified articles were included in the review according to two outcomes(1) Hcy, folate and vitamin B12 blood concentration in HIV-infected subjects vs health controls and;(2) Hcy blood concentration in HIV-infected subjects under ART vs not treated with ART. RevM an(version 5.2) was employed for data synthesis.RESULTS: A total of 12 studies were included in outcome 1(1649 participants, 932 cases and 717 controls). Outcome 1 meta-analysis demonstrated higher plasma Hcy(2.05 μmol/L; 95% CI: 0.10 to 4.00, P < 0.01) and decreased plasma folate concentrations(-2.74 ng/m L; 95%CI:-5.18 to-0.29, P < 0.01) in HIV-infected patients compared to healthy controls. No changes in vitamin B12 plasma concentration were observed between groups. All studies included in the outcome 2 meta-analysis(1167 participants; 404 HIVinfected exposed to ART and 757 HIV-infected non-ART patients) demonstrated higher mean Hcy concentration in subjects HIV-infected under ART compared to nonART HIV subjects(4.13 μmol/L; 95%CI: 1.34 to 6.92, P < 0.01).CONCLUSION: This meta-analysis demonstrated that the levels of Hcy and folate, but not vitamin B12, were associated with HIV infection. In addition, Hcy levels were higher in HIV-infected patients who were under ART compared to HIV-infected patients who were not exposed to ART. Our results suggest that hyperhomocysteinemia should be included among the several important metabolic disturbances that are associated with ART in patients with HIV infection. 关键词：ANTIRETROVIRAL therapy HOMOCYSTEINE Folate VITAMIN B12 Human IMMUNODEFICIENCY virus ACQUIRED immune deficiency syndrome
