Brief Summary:
Even in individuals treated for HIV, chronic immune activation persists and is associated with increased cardiovascular disease, liver disease, and mortality. HIV-infected individuals have imbalances in the community of intestinal microbes which is thought to contribute to increased and persistent inflammation. The purpose of this study is to examine the safety and durability of fecal microbiota transplant (FMT), the transfer of the bacterial community in stool from a healthy donor, in HIV+ individuals on anti-retroviral therapy. The study will also measure the effects of FMT on immune activation and inflammatory biomarkers in anti-retroviral treated HIV+ individuals.
Detailed Description:
Despite antiretroviral therapy (ART), chronic immune activation persists and is a major driver of HIV disease progression and mortality among HIV-infected individuals. Importantly, persistent inflammation is strongly associated with increased cardiovascular events, accelerated liver disease, impaired immunologic recovery (e.g. low CD4 count, low CD4 to CD8 ratio), and mortality. Therefore, addressing persistent inflammation remains a major goal to restoring health in HIV-infected individuals.
Novel therapeutic strategies to decrease immune activation in treated HIV infection are needed. Marked disruption of the gut microbial composition, or dysbiosis, is characteristic of HIV-infected individuals and persists despite long-term ART. Recent studies demonstrate that the relative degree of gut microbiome disruption positively correlates with inflammatory markers (IL-6, kynurenine to tryptophan ratio). Microbial dysbiosis and its inflammatory consequences may be an attractive target for interventions to decrease immune activation in HIV+ individuals.
Fecal microbiome transplantation (FMT) has proven durable and successful as a therapeutic strategy against gut dysbiosis, such as in the treatment of recurrent Clostridium difficile infection, by restructuring the composition of the gut microbiome to resemble that of the healthy donor. FMT has an established record of safety with limited adverse effects, even in the context of immunocompromised and HIV-infected subjects. Donor selection and screening will be conducted by OpenBiome.
The objective of this phase I clinical trial is to establish the safety and durability of FMT in HIV+ individuals. The microbiome of recipients will be analyzed up to 8 weeks post FMT for evidence of engraftment from the donor microbiome. We will further examine the effect of FMT on markers of immune activation and inflammation in ART treated HIV-infected individuals.
