Filter by:The purpose of this study is to develop a pharmacovigilance (PV) surveillance program to monitor adverse pregnancy and infant outcomes, including the presence of congenital abnormalities, among HIV-positive and HIV-negative women and their infants at clinical sites affiliated with the International Epidemiology Databases to Evaluate consortium (IeDEA).
Human immunodeficiency virus-infected (HIV[+]) women have a several-fold increased risk of invasive cervical cancer (ICC) as well as increased risk of cervical pre-cancer. In low- and middle-income countries (LMICs), ICC is the 1st or 2nd most common cause of cancer and cancer-related death in women. Rates of ICC and ICC-related mortality are particularly high in Sub-Saharan Africa, which also has the highest rates of HIV infection in the world. Although prophylactic HPV vaccines may be the optimal cervical cancer prevention strategy, 2-3 generations of at-risk HIV[+] and HIV[-] women are already highly exposed to human papillomavirus (HPV) and would not benefit from (and will not be immunized with) HPV vaccine. Thus cervical cancer screening is needed for the foreseeable future. However, Pap testing is expensive and requires a complex clinical and lab infrastructure that does not generally exist in LMICs; strategies based on high-risk HPV (hrHPV) testing or visual inspection after acetic acid (VIA) are promising but are either too non-specific, leading to over-referral for colposcopy or over-treatment, or are too insensitive, respectively. Thus, inexpensive, easily implemented, and effective cervical cancer screening methods are greatly needed in Sub-Saharan Africa, especially for HIV[+] women. This cervical cancer screening study of 1,200 women (800 HIV[+] and 400 HIV[-] women), aged 25-59 years, living in Cameroon, utilized our existing research site. The investigators evaluated screening tests (hrHPV testing, VIA and Pap), traditional triage tests (HPV16/18/45 detection, VIA, Pap), and promising new biomarkers for triage (Ki-C67, TOP2a, CDKN2A, and HPV viral load) of screen-positive women. All screen positives underwent rigorous disease ascertainment to obtain unbiased estimates of sensitivity, specificity, and positive and negative predictive value. The goal of this study was to establish the foundation and capacity for future studies designed to reduce the burden of HPV-associated cancers in the Cameroon population. It will inform Cameroon and other countries with high HIV burdens on the best strategies for cervical cancer screening in their HIV[+] and HIV[-] women.
The purpose of this study is to develop and assess the feasibility, acceptability, and preliminary efficacy on adherence of a community-informed intervention for tenofovir/emtricitabine (TDF/FTC) pre-exposure prophylaxis (PrEP) engagement among street-based female sex workers (FSW) in Baltimore, Maryland.
Ebola and HIV are found predominately in the same regions of the world and countries in sub-Saharan Africa are most affected by both diseases. For Ebola, no approved therapies exist. However, new investigational drugs are being evaluated to understand if they are effective against the Ebola virus. Remdesivir is an anti-Ebola investigational drug for the treatment of Ebola. Little is known about how the blood levels of remdesivir relate to how effective it is in patients with HIV taking antiretroviral therapy. This study will explore how commonly utilized ART (tenofovir/lamivudine and atazanavir/ritonavir) affect the drug levels of remdesivir.
By combining two strategies (i.e., peer navigation and mHealth) into a complete, culturally compatible, bilingual intervention to increase the use of needed HIV, STI, and HCV prevention and care services among racially/ethnically diverse GBMSM and transgender women in rural Appalachia. Study Investigators anticipate that participants in the intervention group, relative to counterparts in the delayed-intervention group, will demonstrate increased HIV, STI, and HCV testing.
This CDC-funded study sought to evaluate the effect of an adapted Community Score Card Approach on maternal retention in ART, maternal retention across the PMTCT service cascade, and the uptake of early infant diagnosis services in Malawi. The study also estimated the cost of the implementation of the Community Score Card Approach.
This cluster randomized trial will investigate whether messaging about being undetectable equals untransmittable (U=U) designed through a participatory, user-centered approach increases HIV testing uptake within men in Klipfontein Mitchells Plain (KMP) district in Cape Town, South Africa.
AELIX-003 study aims to investigate the safety, tolerability, immunogenicity and efficacy of a regimen containing AELIX Therapeutics' HTI T-cell vaccines and Gilead´s Toll-Like Receptor 7 (TLR7) agonist vesatolimod in HIV-infected individuals on antiretroviral therapy. Study that will be conducted in 57 participants who have started antiretroviral therapy during early HIV infection, enrolled at various clinical trial sites in Spain. All participants will be on antiretroviral therapy upon starting the study, with their HIV viral loads <50 copies/mL. Following exposure to the vaccine/vesatolimod, all participants, under careful monitoring, will temporarily stop their antiretroviral drugs to determine if the intervention is effective in keeping their HIV levels under control.
The goal of this study is to understand the interaction between HIV and the host at the earliest stages when HIV medications are paused. Volunteers with HIV will interrupt antiretroviral therapy (ART) and then have intensive studies preformed two to three times per week. Most will resume therapy within three weeks, even if the virus does not rebound during this time.
Combination approaches will almost certainly be required to generate durable control of HIV in the absence of antiretroviral therapy (a "remission"). In this study, 20 individuals will receive a combination regimen administered during ART and then undergo an analytic treatment interruption (ATI).
