Filter by:The objective of the study is to assess, in a phase 1/2 study, the safety and efficacy of this synthetic vaccine SLP-HPV-01® in HIV+ men with CD4 counts > 350 x 10E6/l and HPV16-induced intra-anal high-grade AIN (grade 2-3) that failed on, or recurred after previous treatment.
The purpose of this trial is to test whether, compared to the normal Standard of Care at primary health care clinics, a home-based counseling intervention ( the 'Amagugu' Counseling Intervention), will increase the number of HIV-infected mothers who are able to disclose their own HIV status to their primary school-aged children. The investigators also wish to examine whether the intervention improves the quality of the maternal-child relationship, emotional and well-being of the child and social support.
UKHVC Spoke 003 is a randomised Phase I, two centre study which will explore the impact of shortening a vaccination regimen using deoxyribonucleic acid (DNA) (CN54ENV and ZM96GPN), Modified Vaccinia Ankara - C (MVA-C) and CN54rgp140 adjuvanted with glucopyranosyl lipid A adjuvant - aqueous form (GLA-AF). The study population will be 40 healthy male and female volunteers 18 to 45 years old who are at low risk of HIV infection are to be recruited. Study participants will be immunised with trial immunogens: - 8mg DNA: one plasmid encoding a gag-pol-nef polypeptide derived from the 96ZM651-8 clone and one plasmid encoding gp140 env derived from clade C 97CN54 - 1.108 TCID50 MVA-C (nominal titre) expressing the gag-pol-nef and gp120 env proteins derived from clade-C 97CN54 - 100ug CN54rgp140, a trimeric recombinant envelope protein derived from clade C 97CN54 - 5ug GLA-AF, an aqueous glucopyranosyl lipid A adjuvant All immunisations will be administered by the intramuscular route (IM). CN54gp140 and GLA will be mixed together before administration, and immunogens will be delivered in combination regimens
The purpose of this Collaborative R01, under Program Announcement PAR-09-153, is to conduct a full-scale trial of an intervention to assist mothers living with HIV (MLH) with disclosing their serostatus to their young age 6 - 14 year old), well children. A pilot study of the intervention has recently been completed (R01 MH077493) and met its major aims. The basis for development of the pilot intervention was work from three R01s (MH057207, currently Yr. 14) designed to longitudinally assess MLH and their children. Within that work, several studies were conducted on maternal disclosure, suggesting disclosure is difficult, and outcomes for MLH and children could be improved by intervention. The pilot study, known in the community as Teaching, Raising, And Communicating with Kids (TRACK), was based on integrative disclosure theory. Results of the pilot trial indicate that those in the intervention group were six times more likely to disclose their HIV/AIDS status to their child than those in the control group (O.R. 6.33); by the 9-month follow-up 33% of intervention MLH disclosed, compared to only 7.3% of the control group. Perhaps more importantly, the intervention group's emotional functioning and their satisfaction improved significantly following the intervention, compared to the control group. Similarly, child mental health indicators among children of intervention MLH were significantly better than control group children at follow-ups. In this study, TRACK II, we propose to conduct a full-scale trial of the intervention in two sites: (1) Los Angeles county (Site 1, where the pilot trial was conducted), which will include a high proportion of Latina families and a smaller proportion of African-American and White families; and (2) Atlanta, Georgia (Site 2, where the primary consultant on the pilot trial conducts research), which will include a high proportion of Southern African-American families, as well as White families. MLH and their children (N = 440 total; 110 mothers and 110 children per site, n = 220 per site) will be assessed at baseline and at 3, 9, and 15-month follow-ups. MLH will be randomly assigned to the intervention or control. Aims are to: 1. facilitate disclosure of the mothers' HIV status to the children, which will include secondary aims of: 1. increasing mothers' self-efficacy to disclose and respond to child questions regarding HIV; 2. reducing mothers' fears regarding disclosure and stigma; 3. improving maternal knowledge of child development and how to provide appropriate levels of information given the age of the child; 2. improve MLH mental health indicators over time (i.e., depression, anxiety, quality of life); 3. improve child mental health indicators over time (i.e., depression, anxiety, acting out behaviors); and 4. improve family functioning indicators (e.g., cohesion, perceived closeness between mother and child).
Retention in care and virologic suppression are the key final steps of the HIV treatment cascade. Poor or intermittent retention has been associated with later initiation of antiretroviral therapy, virologic failure, and death. Regular HIV care has also been associated with a decrease in HIV transmission risk behavior. Despite the proven health and prevention benefits of consistent HIV care, only 40-50% of those infected with HIV in the United States are estimated to meet current retention in care standards and even fewer - only about 25% - are estimated to be virologically suppressed. The Behavioral Model for Vulnerable Populations provides a useful framework for understanding broad areas that may impact adherence to care and treatment. Individual-level domains include vulnerable (e.g., depression, stigma), enabling (e.g., social support, positive affect), and need (e.g., co-morbidities) factors, and structural domains include, for example, features or the clinic and the provider-patient relationship. Short message service (SMS) technology represents a new and exciting tool to help retain HIV-infected patients in care and treatment. SMS interventions have been deployed successfully in support of antiretroviral adherence and virologic suppression in sub-Saharan Africa, where two randomized trials have showed clear benefits. A pilot study conducted in our clinic suggests that use of SMS messages to promote adherence to care and treatment in the urban HIV-infected poor is both feasible and acceptable. The investigators believe that combining SMS technology with content-specific messages designed to impact factors highlighted in the Behavioral Model for Vulnerable Populations can improve retention in care and virologic suppression for an urban public hospital population living with HIV, thus the investigators propose the following specific aims. Specific Aim 1: Determine whether a behavioral theory-based SMS intervention improves virologic suppression [primary outcome] and retention in care [secondary outcome] for a vulnerable urban HIV-infected population through a randomized trial of this technology compared to SMS appointment reminders alone. Retention in care will also be analyzed as a mediator of virologic suppression. Exploratory outcomes include time to virologic suppression, sustained virologic suppression, emergency department utilization and antiretroviral adherence, as well as levels of depression, positive affect, social support and empowerment. Specific Aim 2: Examine patient experiences with the SMS intervention, focusing specifically on: 1) satisfaction with this technology; 2) identifying barriers to and facilitators of patient use of this technology, and; 3) the preferred frequency and content of intervention messages. Specific Aim 3: Conduct cost and cost-effectiveness analyses of the SMS intervention.
To use a systems biological approach to study the molecular signatures of innate and adaptive responses to vaccination in a HIV infected versus uninfected adult population in Kampala, Uganda.
This pilot study is a non-randomized controlled cohort study evaluating the impact of social network-based HIV education on antiretroviral therapy (ART) adherence, clinical outcomes, food security, social support, HIV knowledge, and risk behaviors among people living with HIV/AIDS, as well as members of their associated social support networks. The intervention, known as the Mfangano Health Net Microclinic Pilot Program, consists of a 6-month education program on HIV biology, interpersonal communication and community mobilization for both HIV positive individuals and their self-selected social network members selected irrespective of HIV status. Investigators hypothesize that participation in the microclinic program will improve ART adherence, cluster of differentiation 4 (CD4) count, social support, HIV knowledge and food insecurity and will reduce HIV-related stigma, as compared to participants in control communities.
This is an observational study of HIV-1 negative individuals who participated in demonstration projects or clinical studies and took daily Emtricitabine/Tenofovir Disoproxil Fumarate (FTC/TDF, Truvada®) for pre-exposure prophylaxis (PrEP). All individuals were enrolled and followed as described in the parent PrEP demonstration project or clinical study protocol until study completion, HIV-1 infection, discontinuation due to an adverse event, lost to follow-up, or administrative censoring. In the protocols of the parent PrEP observational or clinical studies, participants had follow-up visits on average every 3 months for evaluation of adherence, renal and bone adverse events, and HIV-1 infection status. Adherence was determined by the specific FTC/TDF drug level measurement(s) outlined in the parent protocol. Gilead had collected data from 21 global PrEP demonstration projects and clinical studies for over 7,000 Truvada for PrEP users who had at least one measurement of adherence. Data from the different contributing studies were pooled for statistical analyses by Gilead.
The study employs a quasi-experimental design in 8 public health centers in southwest Uganda offering care and treatment (C&T) services. In 4 health centers, a basic intervention is introduced, whereby HIV/AIDS providers are trained on contraception for HIV-positive women. They are charged with counseling C&T clients on FP; offering condoms, pills and injectables; and referring clients for other FP methods. In the other 4 health centers, the basic intervention is introduced along with an intervention for constructive male engagement in HIV and FP services. This includes training of C&T providers on gender-based influences on health behaviors; provision of couples' HIV testing and FP counseling services; and community-based education for men to promote gender equitable norms and male participation in health services.
Human Immunodeficiency Virus (HIV) infection is very successfully treated with a type of therapy called Highly Active AntiRetroviral Therapy (HAART). Although HAART has made a great improvement to the health and lives of all people living with HIV, HAART cannot be stopped because it is not able to 'cure' or eliminate the HIV virus from all cells in the body - the remaining viruses are referred to as 'latent' or sleeping virus. As soon as the HAART treatment is stopped the virus comes back (wakes up). It is for this reason that stopping HAART treatment is not recommended. However, it may be that other drugs if given with HAART could have a stronger effect on the latent virus. There is some evidence from laboratory research that suggests that some of the drugs we use to treat certain types of cancer may have an effect on the latent virus. The purpose of this research study is to use new laboratory research technology to measure the amount of 'latent' virus in people who are treated with HAART who then need to use chemotherapy treatments for cancer. We will look at whether the levels of HIV virus are reduced in patients having chemotherapy by looking at the virus levels before, during and after chemotherapy treatment. We do not know very much about how HIV persists in the body despite therapy and unless new approaches are developed, removal of the HIV virus from all cells in the body will not be possible.
