Chronic inflammation predicts complications in persons with human immunodeficiency virus infection. We compared D-dimer, soluble CD14, and interleukin 6 levels before and 12 months after antiretroviral therapy (ART) initiation, among individuals starting ART during earlier-stage (CD4 T-cell count >350/μL) or late-stage disease (CD4 T-cell count <200/μL). Female sex, older age, viral load, and late-stage disease were associated with pre-ART biomarkers (n = 661; P <. 05). However, there were no differences in biomarkers by disease stage after 12 months of ART (n = 438; P >. 05), owing to loss from observation and greater declines in biomarkers in late-stage initiators (P <. 001). Earlier initiation of ART is associated with decreased inflammation, but levels seem to converge between earlier and later initiators surviving to 12 months.
