BACKGROUND/PURPOSE: Early initiation of antiretroviral therapy (ART) reduces the risks for serious infections and mortality. We aimed to assess the outcomes of initiating ART among HIV-positive Taiwanese according to the CD4 cut-off values by the WHO recommendations.
METHODS: We reviewed medical records of patients with newly diagnosed HIV infection between 2004 and 2015 and 3 groups of patients were defined according to the timing of ART initiation based on CD4 count recommended by WHO: Group 1 between 2004 and 2009; Group 2 between 2010 and 2012; and Group 3 between 2013 and 2015. The primary outcome was all-cause mortality. All patients were followed until 2 years after the last patient was included in each group.
RESULTS: Of 2022 patients included, the mortality rate was 18.28, 14.01, and 9.10 deaths per 1000 person-years of follow-up (PYFU) in Groups 1, 2, and 3, respectively. In multivariable Cox regression analysis, factors associated with mortality were age (per 1-year increase, adjusted hazard ratio [AHR], 1.06; 95% CI, 1.05-1.08), presence of AIDS-defining disease at HIV diagnosis (AHR, 4.81; 95% CI, 2.99-7.74), solid-organ malignancy (AHR, 3.10; 95% CI, 1.86-5.18), and initiation of ART (AHR, 0.09; 95% CI, 0.05-0.16). By competing risk regression model for non-AIDS-related death, the AHR for Group 3 versus Group 1 was 0.27 (95% CI, 0.09-0.80).
CONCLUSIONS: While continued efforts are needed to improve early diagnosis and linkage to care, initiation of cART improved survival among HIV-positive patients in Taiwan according to the increasing CD4 cut-off values that were recommended by the WHO.
