Impact of ART on dynamics of growth factors and cytokines in primary HIV infection

Research output: Contribution to journalArticlepeer-review


Antiretroviral treatment (ART) of Primary HIV Infection (PHI) has demonstrated virological and immunological benefits. The effect of early ART during PHI on the level of growth factors and chemokines modulating immune cell functions remains to be established. The aim of our work was to analyze the dynamics of 27 cytokines, chemokines and growth/regulation factors in plasma of HIV infected patients treated during PHI. Patients with PHI (n = 43) were enrolled before, 24 and 48 weeks after therapy initiation. Quantification of soluble immune mediators was performed in plasma from HIV infected patients and healthy donors (HD, n = 7) by Luminex technology. The cytokines profile was strongly perturbed in primary HIV infected patients when compared to healthy donors (HD). After 48 weeks of ART, some of these factors were restored to HD level (IL-2, IL-5, IL-7, IL-9, IL12p70, TNFα) while others persisted higher than HD (IL-6, IL-10, IL-13). Interestingly, a subset of chemokines, such as IL-8, MCP-1, RANTES and CCL27, and growth factors such as HGF, SCF and GM-CSF, increased during ART, reaching values significantly higher than HD after 48 weeks. Moreover, the G-CSF and MIP-1β soluble mediators were persistently altered and showed an inverse correlation with the CD4/CD8 T cell ratio. The increase of chemokines with antiviral activity and of growth factors with hematopoietic and immunomodulatory properties may have beneficial effects. Other studies are mandatory to evaluate the effects of long lasting levels of these factors to clarify their possible role in the context of protection/pathogenesis.
