HIV positive pregnant women who receive potent combination antiretroviral therapy over at least the last trimester of pregnancy, and who have proper obstetric interventions and are able to avoid breast feeding, decrease the risk of having an infected infant to about 1%. Breast milk HIV-1 RNA (cell free) viral load is significantly associated with breast milk transmission, and a 2-fold increased risk of transmission associated with every 10-fold increase in breast milk viral load has been reported. In addition, cell associated virus (HIV DNA) was associated with a significant increase in risk of transmission independent of the level of cell-free viral RNA. However, multiple studies of HIV positive women giving birth have shown that exclusive breast-feeding carries a much lower risk of HIV transmission than mixed breast-feeding (defined as breast milk along with complementary food, other milk, and/or infant formula). The proposed study will measure the antiretroviral (ARV) drug etravirine concentrations in blood and breast milk in postpartum HIV positive women on HAART therapy. The short-term goal is to determine how much etravirine penetrates into breast milk, and whether it leads to undetectable HIV viral load in the breast milk and therefore has the potential to decrease the risk of transmission of HIV through breast milk. The long term goal is to see if breast milk HIV levels can be lowered sufficiently to prevent maternal to child transmission (MTCT) of HIV in infants receiving only breast feeding in resource poor areas.
The primary objective of this study in antiretroviral (ARV)-naïve Human immunodeficiency virus 1 (HIV-1) ribonucleic acid infected subjects is to compare the response rate at Week 48 of a daily regimen of Atazanavir (ATV)/ Ritonavir (RTV)HS 300/100 mg combined with either one additional drug [Lamivudine (3TC) 300 mg daily] or 2 additional drugs [Tenofovir/Emtricitabine(TDF/FTC) 300/200 mg daily].
In optimally managed HIV+ women with undetectable viral loads, who are on HAART and also receiving intrapartum IV ZDV, the risk of vertical transmission of HIV is independent of the length of time of rupture of membranes.
The main purpose of this implementation science study is to find out if providing aPS at 18 different Ministry of Health (MOH) VCT clinics in Kenya works and is cost-effective. This would enable co-investigators in the Kenyan MOH to justify funding to scale-up these services. The primary aim of the study is to find out whether providing aPS to sexual partners of newly tested HIV-infected individuals can result in more sexual partners getting counseled and HIV tested and linked to HIV care programs for initiation of ART if appropriate. The investigators hypothesize that aPS will increase rates of case-finding, linkages to care, and ART initiation and will not result in social harm. The second aim is whether aPS is cost-effective in the Kenyan setting. The investigators will estimate how much it costs (when compared to standard methods) to identify and link HIV-infected persons into care. The investigators will also determine how successful aPS is at preventing future HIV transmission events and other outcomes associated with untreated HIV infection. The investigators hypothesize that HIV prevalence among partners in the immediate aPS arm will be high enough to make this approach cost-effective from the payer and societal perspective. Finally, with the Kenya MOH, the investigators want to establish a nationwide monitoring system to evaluate why Kenyans are testing for HIV. In the future, when aPS is rolled out nationally, this will help Kenyan public health officials define the contribution of aPS to HIV case-finding. The investigators hypothesize that the proportion of newly tested HIV-infected individuals who report testing because of known exposure to a person with HIV will represent a significant proportion of new cases and the investigators will be able to identify places in Kenya where aPS will have the greatest impact on HIV treatment and prevention.
This study will evaluate the efficacy of an integrated "Retention Clinic" in achieving virologic suppression among HIV-infected cocaine (including crack) users by using a two-group randomized, prospective trial. A total of 360 HIV-infected individuals who report cocaine (including crack) use will be randomized across study sites. The primary hypothesis is that more participants randomized to the "Retention Clinic" will have undetectable viral load than will participants randomized to the treatment as usual group.
Primary Objective: This study will evaluate the most effective strategy in achieving HIV virologic suppression among HIV-infected substance users recruited from the hospital setting who are randomly assigned to one of three treatment conditions: 1) Patient Navigator (PN); 2) Patient Navigator + Contingency Management (PN+CM); and 3) Treatment as Usual (TAU). Primary Hypothesis: The rate of viral suppression (plasma HIV viral load of <= 200 copies/mL) relative to non-suppression or all-cause mortality in the 3 study groups will differ from each other at the 12 month follow-up. Sub-hypothesis 1. The rate of virologic suppression (plasma HIV viral load of <= 200 copies/mL) in the PN+CM group will be greater than that in the TAU group. Sub-hypothesis 2. The rate of virologic suppression in the PN+CM group will be greater than that in the PN group. Sub-hypothesis 3. The rate of virologic suppression in the PN group will be greater than that in the TAU group. Secondary Objectives: 1. To evaluate the effect of the experimental interventions on: HIV virological suppression and CD4 T-cell count changes at 6 months post-randomization; engagement in HIV primary care and visit attendance; and rate of hospitalizations. 2. To evaluate the effect of the experimental interventions on: drug use frequency and severity; and drug use treatment engagement and session attendance. 3. To assess selected mechanisms of action of the intervention (.i.e. mediators of intervention effect). 4. To assess potential characteristics associated with differential treatment effectiveness (i.e. moderators of intervention effect). 5. To evaluate the incremental cost and cost-effectiveness of the interventions.
Despite overwhelming need for effective HIV palliative care in sub-Saharan Africa, a systematic appraisal of the literature found almost no outcome or evaluative evidence. Aim: The investigators aim to evaluate the efficacy of HIV palliative care training and a simple palliative care assessment tool provided to nurses of patients on Antiretroviral Therapy (ART), and to evaluate this in terms of patient outcomes under clinical experimental conditions in 2 African countries using randomised controlled trial (RCT) designs. Intervention being tested: Within each well-established HIV ART clinic, patients will be randomly allocated to either continue receiving standard care (control group) or to receive standard care plus appointments with a clinic nurse trained in basic palliative care (intervention group). Methods: Design: Each Phase III clinical trial (i.e. one trial in each of 2 countries) will be powered and conducted in parallel to a common research design protocol, thus permitting evidence of outcomes that reflects 2 different ART providers, providing evidence of palliative care efficacy relevant to different HIV care settings. Primary outcome: Each trial has been powered to a primary endpoint of pain control. Secondary outcomes: The secondary outcomes are the core domains of palliative care as defined by the WHO (i.e. physical, including symptoms, psychological, social and spiritual) and measured by the APCA African POS. Further secondary outcomes measured will be: adherence to treatment; risk behaviours; health-related quality of life; psychological morbidity. Inclusion: Patients will be screened and invited into the trial if they are on ART, score 3-5 on the 0-5 APCA African POS pain or symptom items, are 18 years or older, and can give informed consent to trial entry and data collection. Analysis: An intention-to-treat analysis will be conducted to determine treatment response differences between the two conditions. In order to maximise the efficiency of longitudinal data, multi-level modelling will be applied as appropriate.
The purpose of this study is to determine the proportion of subjects with HIV-1 RNA < 50 c/mL at Week 48 in patients who failed their first line therapy containing a non-nucleoside reverse transcriptase inhibitor (NNRTI) or an integrase inhibitor
This study will evaluate how safe and tolerable a combination of taking three-drugs will be for the purpose of preventing HIV transmission after a high-risk sexual contact exposure in HIV uninfected adults.
