Clinical Trial Summary

This is a prospective cohort study focusing on HIV negative women. The investigators want to learn how the contraceptive methods of depot medroxyprogesterone acetate (DMPA), etonogestrel implant (Eng-Implant), levonorgestrel intrauterine device (Lng-IUD) and the ParaGard® T 380A Intrauterine Copper Contraceptive impact the vaginal immune environment.

Description:

The three proposed aims will evaluate the effect of four contraceptive methods (depot medroxyprogesterone acetate (DMPA), etonogestrel implant (Eng-Implant), levonorgestrel intrauterine device (Lng-IUD) and ParaGard® T 380A Intrauterine Copper Contraceptive) on: (1) HIV target immune cells within the female genital mucosa; (2) markers of T-cell activation and trafficking within the female genital mucosa; and (3) secreted cytokines and chemokines within the female genital mucosa.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percent of HIV Target Immune Cells Within Female Genital Mucosa and Blood	Following exposure to HIV, initial infection occurs at the genital mucosa and may involve complex interactions between a number of HIV target immune cells. HIV often uses C-C Chemokine Receptor Type 5 (CCR5) for entrance into target immune cells, causing infection of the cell. The amount of CCR5 expressing macrophages is associated with HIV infection. Cluster of differentiation 4 (CD4) T Cells are targeted and infected by HIV and CD4 percentages are used to assess immune status. CD4 counts vary by individuals and generally decrease with HIV infection.	Week 1, Week 17
Primary	Ratio of CD4/Cluster of Differentiation 8 (CD8) T-Cells Within Female Genital Mucosa and Blood	CD4/CD8 ratios above 1 indicate a strong immune system while lower ratios indicate a viral infection.	Week 1, Week 17
Primary	Percent of Markers of T-cell Activation and Trafficking Within the Female Genital Mucosa and Blood	T cell activation correlates with HIV infection progression and this study seeks to gain better understanding of these underlying mechanisms by assessment of HIV target cells. Changes in cluster of differentiation 38 (CD38) expression are indicators of HIV disease progression with increases seen in CD38+ when a chronic HIV infection is progressing. Human leukocyte antigen-antigen D related (HLA-DR)+ expression appears to be involved in HIV proliferation.	Week 1, Week 17
Primary	Concentration Levels of Secreted Cytokines and Chemokines Within the Female Genital Mucosa and Blood	The concentration levels of interleukin 1 (IL-1) family cytokines and interferon gamma-induced protein 10 (IP-10) chemokines were determined using multiplex Luminex® assays combined with a customized multi-analytical panel of 22 human cytokines and chemokines. IL-1 and IP-10 have been found to influence recruitment of HIV target cells to the female reproductive tract and this study is examining changes in IL-1 and PI-10 to gain further understanding of these mechanisms.
