Brief summary

As explained in detail in a recently published hypothesis article (Hladik F. A new hypothesis on HIV cure. F1000Research, 4:77 (2015)), the investigators hypothesize that NRTI drugs may reduce the likelihood of HIV eradication by promoting the survival of cells with integrated provirus. In this study, the investigators will test whether daily oral use of two NTRI drugs, tenofovir and emtricitabine (Truvada Pill), induces changes in the upper and lower gut mucosa that are congruent with supporting this hypothesis.

Interventions

PROCEDUREUpper endoscopy

Upper endoscopy with biopsies

PROCEDUREAnoscopy

Anoscopy with biopsies

DRUGTruvada

Truvada (tenofovir/emtricitabine) daily as HIV pre-exposure prophylaxis. This medication will not be provided by the study.

Inclusion criteria

* • HIV-negative * Male gender at birth * Age ≥18 years old * Intent to initiate PrEP in the next 1-2 months. * Willingness and ability to provide informed consent for study participation * Willingness to undergo all required study procedures

Exclusion criteria

* Creatinine clearance \< 60mL/min * Platelet count below the normal reference * Coagulation (PT/PTT) tests above the normal reference * Any prior use of PrEP * Use of PEP within 30 days prior to study entry * Receipt of * anti-coagulant medications (e.g. warfarin). Aspirin is allowable. * Systemic corticosteroid medications * Non-steroidal anti-inflammatory drug (NSAID) use \>2 days/week * Signs or symptoms of acute HIV infection within 14 days of study entry * No availability of another person who will drive participant home on days of entry and follow-up procedures. * Plan to leave the Seattle area in the subsequent 2.5 months * Any condition or substance use that, in the opinion of the study investigator, would interfere with study participation.

Design outcomes

Primary

MeasureTime frameDescription
Global Transcriptome Analysis2-3 months after initiating HIV Pre-exposure prophylaxisGlobal transcriptome analysis tests for expression changes of any possible gene across the entire human genome in response to Truvada PrEP. The main outcome of such an analysis is the number of genes significantly changing in expression between before and after treatment. We will report that Truvada PrEP up-regulates X number of genes and down-regulates Y number of genes.
