OBJECTIVE: The aim of this proof of concept study was to determine the effect of depot medroxyprogesterone acetate on host and viral factors in HIV infected and uninfected women. RESULTS: In this study, the gene expression levels for CCL5, CCR5 and CXCR4 was significantly higher in HIV positive women when compared to HIV negative women (p < 0.05). An upregulation of CCR5 and CXCR4 was evident in less than 20% of the HIV infected women and none of the HIV uninfected women. The mean fold change for CCL3 was much higher in HIV uninfected when compared to infected women with a borderline significance (p = 0.062). In HIV uninfected women, the mean fold change in CCL3, CCL4, and CCL5 gene expression was not statistically different between women on DMPA versus women not on hormonal contraception. The proportion of women with an upregulation of CCL4 and CCR5 was higher in HIV infected women on DMPA. There was no association between endogenous progesterone level and chemokines and the HIV-1 receptors. The gene expression levels in the chemokine receptors CCR5 and CXCR4 were significantly higher in the HIV infected women when compared to the women who remained HIV uninfected.
