Filter by:This study is a randomised double blind placebo controlled trial comparing Rosuvastatin with placebo in HIV positive people who are at intermediate cardiovascular risk. It is possible that HIV positive people will receive a greater benefit from statins because of their higher baseline levels of inflammation. Current Australian guidelines recommend initiation of statin therapy on the basis of cholesterol level and the presence of other risk factors for heart disease (such as diabetes) but do not take into account whether a patient is infected with HIV. This study aims to determine what benefit HIV infected people will receive from starting statin therapy earlier then currently recommended.
Prospective, open-labelled study which will enrol 360 participants in four groups of 80 participants including: HIV-uninfected adults without evidence of TB; HIV-infected adults without any evidence of TB; HIV-uninfected adults with concurrent microbiologic confirmed TB, HIV-infected adults with concurrent microbiologic confirmed TB. Participants will receive the recommended seasonal 2013 un-adjuvanted Trivalent Influenza Vaccine (TIV). At 3 visits, blood will be collected for determination of immune responses. Objective: • To determine the effect of HIV-infection, tuberculosis (TB) and HIV-TB co-infection on immune responses
In 2012, the WHO Strategic Advisory Group of Experts (SAGE) concluded that pregnant women are the most important risk group for season influenza vaccination based upon "compelling evidence of substantial risk of severe disease in this group and evidence that seasonal influenza vaccine is safe and effective in preventing disease in pregnant women as well as their young infants, in whom disease burden is also high". Recent data from Kenya, similarly suggest rates of influenza-associated hospitalizations in children under age 1 to be as high, or higher, than those observed in the United States. However, TIV may have reduced immunogenicity in HIV-infected adults, and HIV infection has been shown to reduce placental transfer of both tetanus and measles antibodies. Therefore, we propose to conduct a double-blind randomized controlled trial of influenza vaccines stratified by HIV status in up to 720 pregnant women in their second and third trimesters and their infants residing in health and demographic surveillance sites (HDSS) in Nyanza Province, Western Kenya. We propose to assess the safety, immunogenicity, and efficacy of standard dose QIV and double dose QIV in HIV-infected and HIV-uninfected pregnant women. Findings will inform maternal influenza vaccination policies in Kenya and other African countries.
START is clinic-level (not individual-patient) intervention to catalyze the process of ART initiation among HIV-infected adults who meet CD4-based criteria for combination ART (e.g., adults with a CD4 T cell level < 350/ul). The three START components are: (1) real-time point-of-care CD4 testing using the Alere PIMA platform to ascertain treatment eligibility in real time at first presentation to care, (2) targeted knowledge transfer (i.e., dissemination) of recent scientific evidence regarding effects rapid ART initiation on survival to front line health care workers; and 3) feedback and reporting to clinic and providers. There three components represent empirically validated steps in the PRECEED implementation model.
Black men who have sex with men (MSM) Pre-Exposure Prophylaxis (PrEP) Study with Client Centered Care Coordination (C4)Component.
The purpose of this study is to see if taking two nutritional supplements, zinc and SAMe (S-adenosylmethionine), can improve lung health and immune function in persons with HIV. You are being asked to volunteer because you have HIV (Human Immunodeficiency Virus) and you take anti-retroviral therapy (ART) medications.
Each year, an estimated 230,000 HIV-infected women in need of services for prevention of mother-to-child transmission of HIV (PMTCT) give birth in Nigeria, more than in any other nation in the world. Vanderbilt University (VU), through its affiliate, Friends in Global Health (FGH), is currently supporting HIV/AIDS services in North-Central Nigeria. These sites are predominantly rural primary health centers (PHCs) where shortages of high-cadre health care providers and insufficient laboratory capacity to perform CD4+ cell count testing have been major barriers to effective PMTCT scale-up. A systematic reassignment of patient care responsibilities coupled with the adoption of point-of-care (POC) CD4+ cell count testing will facilitate the ability of lower-cadre health providers to manage PMTCT care, including the provision and scale-up of antiretroviral treatment (ART) to pregnant women in these rural, decentralized sites. A system wherein men are facilitated to accompany their wives to ANC appointments will create an important opportunity to address entrenched gender norms. The investigators therefore propose using community and facility-based measures to encourage male partners to accompany their spouses for ANC. As influential community members, male partners can assist their spouses to utilize culturally-sensitive, sustainable and integrated PMTCT care provided by lower-cadre providers in these resource-constrained settings. The investigators propose a parallel, cluster randomized trial to evaluate the impact of a family-focused PMTCT package that includes: 1) task-shifting to lower-cadre providers at PMTCT sites; 2) POC CD4+ cell count testing; (3) integrated mother-infant care; and (4)) a prominent role for influential family members (male partners), working in close partnership with community-based health workers/volunteers. The specific aims of this study are: 1. To evaluate whether implementation of the integrated PMTCT package in primary level antenatal clinics (ANC) increases the proportion of eligible pregnant women who initiate antiretroviral medications for the purposes of PMTCT. The investigators hypothesize that the provision of the PMTCT package in intervention clinics will improve PMTCT antiretroviral uptake rates among eligible women during pregnancy from 40% to 65%. 2. To determine whether implementation of the PMTCT package improves postpartum retention of mother-infant pairs at 6 and 12 weeks. The investigators hypothesize that postpartum retention rates among mother-infant pairs attending intervention sites will be >20% higher at 6 weeks when compared to mother-infant pairs receiving care in non-intervention sites. 3. Conduct a cost-effectiveness analysis (CEA) of the impact of this novel PMTCT intervention compared to the existing standard-of-care referral model. The investigators hypothesize that the proposed intervention will be more cost-effective than the existing model of care. In addition, two qualitative evaluations will be conducted in order to: 1. Assess client satisfaction with health services, comparing PMTCT services provided by lower level vs. higher level cadre health workers; and 2. Evaluate health care worker satisfaction with the new PMTCT service delivery model.
Background: Approximately 6.4% of Ugandans are living with HIV, that is acquired and transmitted mainly through sexual intercourse between an HIV infected and uninfected person. Uganda is ranked among 28 top per capita alcohol consumers in the world and second in Africa. in the general population, Alcohol consumption is associated with increased sexual transmission risks for HIV. Data on alcohol consumption and its impact on sexual behaviors and HIV disease progression among HIV infected persons, the persons able to transmit HIV are lacking in this setting. Objectives: To estimate the prevalence of alcohol consumption among HIV infected persons, assess associations between alcohol and CD4 cell count as well as evaluate the effect of alcohol motivational intervention counseling on alcohol consumption and the subsequent practice of risky sexual behaviors, among HIV infected persons. Methodology: Using both cross-sectional and longitudinal methods,persons living with HIV/AIDS (PLWHA) attending the Infectious Diseases Institute Clinic (IDI clinic) will be recruited, baseline alcohol consumption evaluated, and eligible subjects reporting alcohol consumption will be randomized to receive either Standard positive prevention counseling alone or in addition to alcohol motivation intervention counseling. Sexual risk behaviors and alcohol consumption will be evaluated at 3 and 6 months and compared between randomization arms.
Medium and long term efficacy of PI-based 2nd line antiretroviral (ARV) therapy in Cambodia is poorly documented when the numbers of patients on treatment and their duration are increasing. For patients in treatment failure , there is no alternative ARV regimen available to date. This operational research aims to evaluate the Cambodian National Program PI-based 2nd line antiretroviral regimen to assess the proportion of treatment failure and drug resistance ;identify the structural and individual factors associated with treatment failure ; design alternative salvage ARV regimens.
The present study includes a randomized clinical trial of a peer health education intervention and a 12-month longitudinal study. The sample will include Black Men who have Sex with Men (MSM) who will be randomized into an experimental or control condition and then asked to recruit peer and risk network members for HIV testing over a 3 month period. Some of the network members who are recruited for voluntary counseling and testing (VCT) will enroll into the longitudinal study for assessments only. Both index and network participants will be assessed at baseline, 6, and 12-months. The specific aims of the proposed study are to: 1. Train Black MSM (index participants in the experimental condition) to conduct peer health education, to promote VCT and HIV risk reduction among social network members, and to recruit social network members for VCT. 2. Examine changes in HIV risk behaviors and VCT among index participants and their network members in the experimental intervention as compared to those in the control condition. 3. Examine mediating effects of social environments (networks, social norms) on HIV risk behaviors and VCT, among indexes and network members. 4. Examine mediating effects of individual level factors (substance use and depression) on HIV risk behaviors and VCT among indexes and network members.
