Filter by:This will be a cross-sectional population-based study carried out in the region of Madrid (6,468,322 inhabitants according to current census) to quantify the number of Co-meds in HIV-infected individuals on ART in the region of Madrid, categorized by age and gender, and to compare the number of Co-meds between the ART-treated population and HIV-uninfected population in the region of Madrid, categorized by age and gender.
The primary objective is to compare & evaluate between the treatment groups the changes in decline/reduction of HIV viral load changes in the Remune + Amplivax group vs the Amplivax placebo groups. Additional objectives include changes in WBC White Blood Cell counts & CD4+ & CD8+ T cell counts along with increased HIV immunity.
Background: Data are scarce concerning injecting drug use (IDU) and alcohol consumption among HIV-infected people on highly active antiretroviral treatment (HAART) in Cameroon. The aim of this study is to determine the prevalence of alcohol consumption and IDU among HIV-infected people on HAART; to determine sociodemographic factors associated with alcohol abuse and IDU among people on HAART; and to determine impact of alcohol consumption and IDU on adherence to HAART. Methods/Design: The investigators will conduct a cross sectional study at the Yaoundé Central Hospital in Cameroon, from February to August 2015. Using a self-report questionnaire, the investigators will include at least 1,000 HIV-infected adults (18 years or more) on HAART for at least one month coming for HIV care. The investigators will exclude pregnant women. Data collection will include sociodemographic and economic profile, alcohol consumption using Alcohol Use Disorders Identification Test, injecting drug use, adherence to HAART using visual analog scale and self-rate report. The investigators will perform sub-analysis for sex group and area of habitation. A p value < 0.05 will be considered statistically significant. Discussion: There is a critical need of accurate estimates of the amplitude and the distribution of IDU and alcohol consumption among HIV-infected adults, in order to inform health policies maker for curbing burden of both injecting drug use and alcohol consumption among people living with HIV.
Tremendous efforts and resources have been expended by the global community to ensure that antiretroviral therapy (ART) is available and accessible to all that need it. Despite these, less than a half of Human Immunodeficiency Virus (HIV)-infected patients requiring ART in sub-Saharan Africa (SSA) are receiving it. Some of the most significant barriers to attaining universal access to ART in this region include large distances that patients have to travel to clinic, time spent in accessing care and a significant shortage of human resources. In order to address these challenges the World Health Organization (WHO) advocates alternative care models especially those that incorporate task-shifting to lower cadre health care workers and lay persons. Unfortunately, few such alternative care models have been identified and very little data exist on their long-term outcomes. With this project we will develop and assess an alternative care model that is established on the platform of a HIV-infected peer-group (ART Co-op) and facilitated by community health workers (CHW's). This model of care is intended to decentralize ART services and bring them closer to the patients. Specifically, we will: 1. Develop an acceptable and sustainable model for extending HIV care and treatment into the community. 2. Perform a pilot study comparing the outcomes of patients enrolled in the ART Co-ops program to those receiving standard of care. 3. Determine the cost savings and cost effectiveness of ART Co-ops.
This is a phase IV, open label, multicentre trial that will be taking place at 4 sites in the United Kingdom (UK). Efavirenz which is taken in combination with Kivexa® or as part of the combination pill, Atripla® is a recommended firstline regimen for the treatment of Human Immunodeficiency Virus-1 (HIV- 1) infection. Treatment against the HIV virus is also referred to as antiretroviral therapy. Toxicity is the most common reason for modification of firstline therapy. Central Nervous System (CNS) side effects such as difficulty with sleeping & bad dreams are common side effect of Efavirenz based therapy and is one of the most frequent reasons for switching or discontinuing highly active antiretroviral therapy. Dolutegravir is within a novel class of antiretroviral agents licensed in the UK for the treatment of HIV. In combination with Truvada®, it showed fewer side effects when compared to Efavirenz in other clinical studies, where patients were starting HIV treatment for the first time, or switching from other agents. The purpose of the study is to investigate the benefits of switching away from Eefavirenz (in combination with Kivexa® or as part of the combination pill, Atripla®) to Dolutegravir in patients with CNS side effects (such as difficulty with sleeping, bad dreams etc).
The purpose of this study is to assess the utility of the Theory of Planned Behavior in predicting condom use among men who have sex with men. It also aims to assess the utility of two interventions, one known as "implementation intentions", the other involves the practice of a planning task known as "the tower of Hanoi", in increasing condom use in this population.
This will be a pilot, open label study involving 65 participants. All participants will be followed until seroconversion or until the last enrolled participant completes one year of follow-up, whichever happens first. Participant study number will be given at the screening visit, prior to inclusion in the study. The chosen intervention and study regimen are based on the dynamics of viral infection and the pharmacokinetics of the study drugs. In order to inhibit reverse transcription nucleoside and nucleotide analogues need to be phosphorylated intracellularly. On the other hand, available data indicate that it takes approximately 10 hours between exposure and HIV viral integration, offering a window of opportunity for Raltegravir to block integration and thus prevent infection, given that this drug does not need to be metabolized to exert its effect. The intervention will be maintained for 4 weeks following exposure, in accordance with Brazilian and CDC guidelines for PEP.
The purpose of this study is to determine whether the use of a Computerized Decision Support System (CDSS) in form of alerts to clinicians enhances early detection of immunological treatment failure in HIV patients.
HBV vaccination is of paramount importance among HIV positive persons due to an increased risk of infection and disease progression. The most widely used ENGERIX B vaccine reaches a lower rate of vaccination (20-70%) among HIV positive vaccinees (compared to over 90% in the normal population). Sci-B-Vac is novel vaccine containing 3 antigens and is therefore more immunogenic (as opposed to one in ENGERIX B). Its use has been associated with higher and more rapid vaccination rates. Therefore, it has a theoretical advantage in HIV positive individuals.
Patients infected with Human Immunodeficiency Virus (HIV) are at risk of brain related complications despite the use of highly active antiretroviral therapy (HAART). Such complications are termed HIV neurocognitive disorders (HAND) and comprise a spectrum from asymptomatic neurocognitive impairment (ANI), through mild cognitive impairment (MCI) to severe HIV dementia (HAD). Prior to HAART approximately 30% of patients with advanced HIV disease had cognitive impairment; with HAART the incidence of HAND has decreased but its prevalence increased. The reasons for the ongoing development of cognitive impairment in HAART treated patients are not clear. They might relate to virus induced brain injury prior to starting HAART, the onset of a separate neurological process, toxicity related to HAART, or ongoing viral infection in the brain. It is clear that the ability of different antiretroviral drugs to penetrate the brain varies but what is not established is whether these differences between drugs lead to different neurological outcomes. The investigators propose to study HIV infected patients stable on HAART for 12 months; subdividing the groups according to the brain penetrance of their drug combination. Patients would undergo neuropsychological assessment and MRI brain scan at the start of the study and after 12 months. At study initiation a lumbar puncture would be performed so that drugs levels could be measured in CSF. Differences in neuropsychological tests and MRI would be sought between treatment groups to establish whether HAART with better CNS penetration is associated with better outcome and fewer MRI changes.
