Abstract Chronic HIV infection induces significant changes in the trafficking of circulating endothelial progenitor cells (EPCs). Specifically, it causes marked depletion of proangiogenic hematopoietic cells, the so-called colony-forming unit-endothelial cells (CFU-ECs). In this study we evaluated CFU-ECs in two subjects with acute HIV infection. We found that both patients already had a low CFU-EC level at the time of diagnosis. Nevertheless, after 6 months of antiretroviral therapy, the CFU-EC concentration reverted to normal values in both cases. HIV significantly depletes the CFU-EC compartment even in the early phase of infection, while 6-month therapy appears to be able to restore it.
