The impact of highly active antiretroviral treatment on the blood profiles of patients with acquired immune deficiency syndrome.

This study retrospectively investigated the short- and long-term impact of highly active antiretroviral treatment (HAART) on the blood profiles of patients with acquired immune deficiency syndrome (AIDS), and their relationship with disease progression. CD4(+) T-cell count was measured by flow cytometry, plasma viral load of human immunodeficiency virus (HIV) RNA was detected by reverse transcription-polymerase chain reaction, and blood profile was determined by an automated analyser. CD4(+) T-cell count, total lymphocyte count (TLC) and haemoglobin concentration improved gradually in patients with AIDS after the initiation of HAART. Long-term effective HAART significantly increased CD4(+) T-cell counts TLC and haemoglobin concentrations, and reduced viral load to undetectable levels. An increase in haemoglobin was positively correlated with an increase in CD4(+) T-cells. These findings suggest that TLC is a valuable tool for determining the initiation of HAART, and that the haemoglobin concentration could be an additional indicator for long-term monitoring of HAART in resource-limited settings.
