OBJECTIVE:To explore risk factors for the death in HIV/AIDS patients suffering from myelosuppression during highly active antiretroviral therapy(HAART)treatment. METHODS:The historical cohort study method was used to choose 735 in-patients from Nanning Forth People's Hospital during Jan. 2011 to Jul. 2015. Univariate and multivariate Logistic regression analy-sis were used to show the risk factors for the death. RESULTS:Of 735 cases,there were 648 survival cases and 87 dead cases, with mortality of 11.8%. Univariate Logistic analysis showed that:male,elder,higher total bilirubin,lower creatinine clearance, lower CD4+T cell count in baseline,combined more opportunistic infection,combined more myelosuppressive drugs,thrombocyto-penia,lower hemoglobin were the risk factors for the death of HIV patients with myelosuppression in HARRT treatment,while route of HIV infection,HAART treatment A including Zidovudine,weight were the protective factors. Multivariate Logistic regres-sion analysis showed male,elder,higher total bilirubin,lower creatinine clearance,lower CD4+ T cell count in baseline,com-bined more opportunistic infection,combined more myelosuppressive drugs,thrombocytopenia,lower hemoglobin were the risk factors for the death of HIV patients with myelosuppression in HARRT treatment too. CONCLUSIONS:Pertinence treatment and control methods for HIV/AIDS with myelosuppression in HARRT treatment should be taken to reduce the mortality in the future.
