Advanced immunosuppression at entry to HIV care in the southeastern United States and associated risk factors.

In this study we characterized factors associated with the late initiation of HIV care in the southeastern United States. At initiation of care, antiretroviral therapy was indicated for 75% of patients, 50% had a CD4 cell count of less than 200 cells/mul, and 27% presented with an AIDS-defining illness. Male sex was an independent predictor in multivariable analysis. These results indicate an urgent need to increase HIV testing for earlier diagnosis in the southeastern USA.
