Filter by:The investigators propose to develop and pilot an HIV prevention intervention based on rectal STI testing, counseling, and treatment for MSM in Peru. The investigators will use nucleic acid testing to screen 750 behaviorally high-risk MSM for rectal gonorrheal and/or chlamydial (GC/CT) infection. GC/CT-positive subjects will receive single-dose antibiotic treatment and single-session Personal Cognitive Counseling (PCC) (n=50) or standard post-test counseling (n=50). A GC/CT-negative control group (n=50) will also be enrolled to compare biological outcomes including changes in levels of inflammatory cytokines following rectal STI. The intervention is based on three interrelated objectives: 1) To use periodic rectal STI nucleic acid testing to identify the members of the MSM population at greatest short-term risk for HIV infection; 2) To provide single-dose antibiotic treatment to control the immune activation and mucosal inflammation caused by rectal GC/CT infection that increase cellular risk for HIV transmission; and 3) To use Personal Cognitive Counseling (PCC) to understand and modify recent high-risk sexual practices that led to rectal STI acquisition and that increase future HIV risk. The investigators propose to screen 750 behaviorally high-risk MSM for rectal GC/CT infection to enroll 100 GC/CT-positive individuals (using a conservative 15% prevalence estimate) and 50 GC/CT-negative controls (matched by age and baseline frequency of URAI). GC/CT-infected participants will be given single-dose antibiotic therapy and randomized to receive single-session PCC (n=50) or standard post-test counseling (n=50). The primary outcome will be the impact of PCC on self-reported sexual risk behavior (URAI). Secondary outcomes will assess: 1) Feasibility/Acceptability of the STI screening program; 2) Impact of GC/CT infection and treatment on levels of inflammatory cytokines (IL-6, IL-8, TNF-αand IL-1β) in rectal mucosa; 3) Prevalence of persistent/recurrent rectal GC/CT; and 4) HIV incidence in GC/CT-infected and -uninfected MSM.
Late diagnosed HIV-infected subjects show impaired immunological recovery resulting in a greater risk of clinical progression. Gut bacteria metabolism appears to impact immune recovery in HIV-infected subjects, and while nutritional interventions with prebiotics and probiotics seem to exert immunological effects, the clinical implications in this key population remain unknown. This is a pilot multicenter randomized placebo-controlled, double blind clinical trial in HIV-infected ART-naive subjects with <350 CD4 T cells/mm3 or AIDS. Participants will be randomized (1:1) to either the synbiotic nutritional supplement PMT25341 or placebo for 48 weeks, each in combination with first-line ART. Primary outcomes will be safety and immunological recovery. Secondary outcomes will include changes in fecal microbiota structure and plasma inflammatory markers.
Altered interplay between gut mucosa and dysbiotic bacteria during HIV infection seems to contribute to chronic immune dysfunction. Manipulation of the intestinal microbiota with nutritional interventions exert limited immunologic effects, but a deep understanding of how these interventions could ameliorate gut dysbiosis and influence health among HIV-infected individuals remain unexplored. In this Phase I clinical trial, 30 HIV-infected subjects on effective ART with evidence of persistent immune dysfunction, indicated by a CD4/CD8 ratio<1 will be included and randomized to either repeated low-dose oral fecal microbiota transplantation or placebo during 8 weeks. The primary outcome will be safety. Secondary outcomes will include changes in CD4+ T cell counts, CD8+ T cell counts, CD4/CD8 ratio, inflammatory markers, T cell activation and markers of enterocyte barrier function through week 48. Engraftment on host microbiota will be examined using Illumina sequencing of the V3-V4 16S RNA, and changes in bacterial metabolism and in the plasma metabolite fingerprint will be studied by combination of untargeted mass spectrometry and two different and complementary separation techniques in bacterial and plasma samples.
The purpose of this study is to evaluate the safety and immune response to an HIV clade C DNA vaccine and to an MF59-adjuvanted clade C Env protein in healthy, HIV-uninfected adults.
This is a retrospective observational multicenter cohort study based on 271 consecutive HIV-HCV coinfected patients who underwent liver transplantation (LT) between 2002 and 2012 in 23 centers from Spain and who were prospectively followed until January 2016. The main objective of this study is to analyze the effectiveness and safety of 2 nucleoside reverse transcriptase inhibitors (NRTIs) plus Raltegravir (RAL)- based antiretroviral therapy (ART) compared to other antiretroviral regimens in liver transplant (LT) HIV-HCV co-infected recipients. In addition, the investigators want to know the rejection rates in patients taking RAL-based ART in comparison with other ART-regimens and to know the efficacy and safety of direct antiviral agents (DAAs) against HCV in HIV-infected liver transplant recipients taking RAL-based ART.
The purpose of the ABX464-005 study is to characterize the systemic and mucosal immunological sequelae associated with exposure to ABX464 and to explore selected immunological endpoints, compartmental pharmacokinetics, and pharmacodynamics.
The purpose of this study is to determine the ability of new anti-HIV agents to penetrate different body compartments in HIV negative men who have sex with men and transgender women. These new agents might be considered for pre-exposure prophylaxis regimens in the future. This study will include 90 healthy, HIV-negative men who have sex with men and transgender women who are not taking hormones aged 18-49 years. Participant must be willing to participate in 1 of the 3 study phases, be willing to take Truvada® (PrEP) or Genvoya®, and willing to undergo blood draws, urethral swabs, and rectal biopsy procedures.

This two-arm cluster randomized trial tested a gender-focused comprehensive HIV testing and counselling (HTC) program, the Young Women's Health CoOp (YWHC) with a standard HTC program and targeted female adolescents (aged 16-19) who use substances and have dropped out of school. To evaluate the process, the study examined the feasibility of using peer role models as recruiters and co-facilitators of the intervention and monitored fidelity to the intervention. Efficacy of the intervention on behavioral and biological outcomes, and on linkages to health services, through follow-up visits conducted 6- and 12-months post-enrollment was also assessed.
The purpose of this research study is to determine the best way to increase screening for cervical cancer, colorectal cancer, HIV, and Hepatitis C among under screened Hispanic, Haitian and African-American individuals in Hialeah, South Dade, and Little Haiti. The investigator will compare home testing led by a community health worker (CHW) versus clinic testing guided by a CHW. Community Health Workers are people who have undergone several weeks of community outreach and health education training. During the study period the participant will continue to receive all of their regular medical care from their regular health care providers. If the participant does not have a health care provider, the Community Health Workers would be able to help in referring the participant for care at a local health care clinic located in their community.
