Study Hypothesis: The addition of selenium supplementation to cotrimoxazole will improve CD4 counts, decrease opportunistic infections, decrease viral loads and delay the need for initiating antiretroviral therapy(ART) in Rwandan adult patients infected with HIV/ AIDS.
This study is an investigation of the pharmacokinetics of raltegravir in the tissue of the female genital tract to determine if twice-daily dosing of 400mg achieves adequate drug levels to prevent viral integration of HIV-1. The study will also assess whether drug levels change in the tissue across the different phases of the menstrual cycle. - Hypothesis #1: Twice daily dosing with raltegravir 400mg will result in intracellular concentrations that should be sufficient to suppress HIV-1 replication throughout the menstrual cycle. - Hypothesis #2: Intracellular genital raltegravir peaks will be lower and troughs higher compared to extracellular concentrations in the plasma and PMBCs (peripheral blood mononuclear cells). - Hypothesis #3: Intracellular raltegravir concentrations will be slightly lower during the luteal phase of the menstrual cycle due to cellular pumps such as p-glycoprotein, which are present in higher numbers during periods of high progesterone.
HIV-infected patients have an increased incidence of emphysema compared to non-HIV-infected patients, and it has been hypothesized that this accelerated disease progression is the result of one or more latent infections that amplifies the pulmonary inflammatory response. The investigators will examine the prevalence and progression of emphysema in subjects with and without HIV and determine risk factors for emphysema in this population.
This study aimed to evaluate the safety and reactogenicity of two intramuscular injections of two different dosages of an investigational clade B HIV vaccine.
The innate immunity of the vaginal tract provides first-line defense from abnormal microorganisms or overgrowth of common organisms, such as Candida species or Gardnerella vaginalis. It is unclear from the current available literature whether the rate of vaginal infection increases or decreases in frequency during pregnancy when compared to the non-pregnant state, but this may be predicted by shifts in vaginal innate immunity. Vaginal infections are important players in HIV disease, potentially increasing the risk of viral transmission. In addition, these infections may activate inflammatory markers in the reproductive tract and increase the risk of premature delivery or other negative pregnancy outcomes. The vaginal innate immune system has not been well characterized in pregnant women, or in women with HIV infection. The study of how this system changes in pregnancy and HIV infection will provide essential knowledge for further study of vaginal mucosal protection. The investigators study is an observational study designed to compare levels of vaginal innate immunity markers in women based on a) pregnancy status and b) HIV infection status. Comparisons will be made between pregnant and non- pregnant women and between HIV positive and HIV negative women. The investigators hypothesize that there will be significant differences in levels of innate immunity between the groups.
The relevance of this research to public health is to make it possible to test for hepatitis C and syphilis at point of care so that people will receive their results immediately instead of requiring people to wait for at least a week to get their test results. This research will make rapid tests for HIV available that can detect HIV infection earlier and are more accurate than current tests available in the United States.
Methamphetamine (METH) is a debilitating and frequently abused substance that is often comorbid with HIV infection. HIV+ persons with current METH abuse or dependence (HIV+/METH+) have several characteristics, in addition to their substance use, that make them particularly susceptible to nonadherence to antiretroviral treatment (ART) including elevated rates of neurocognitive impairment, co-occurrence of psychiatric disorders, and unstable living situations. The investigators propose an intervention development study designed to address these potential mechanisms of nonadherence with the following Specific Aims: 1) To further develop and refine a personalized, automated, real-time, mobile phone, text messaging intervention (iTAB) designed to improve adherence to ART medications among HIV+/METH+ persons; 2) To evaluate the acceptability and effectiveness of a brief psychoeducation plus text messaging intervention (iTAB) as compared to psychoeducation alone (CTRL) for the improvement of objectively measured medication adherence among HIV+/METH+ persons; and 3) To examine predictors of within-person trajectories of nonadherence using the longitudinal data collected over the study. In order to realize these aims, the investigators will leverage the infrastructure of two unique UCSD resources increasing likelihood of study success, impact, and innovation: 1) the Translational Methamphetamine AIDS Research Center (TMARC), which is a NIDA-funded center that focuses on the combined effects of METH and HIV infection, and 2) the California Institute for Telecommunications and Information Technology (Calit2), which conducts research on state-of-the-art wireless means of health promotion. Initially, the investigators will refine the iTAB intervention to ensure that it is user-centered and tailored to the needs of HIV+/METH+ persons via focus groups and rapid prototyping. Once refined, the proposed iTAB intervention will use text messages that are automated, scalable, personalized, interactive, flexible, and motivating. The investigators will assess the acceptability and effectiveness of iTAB in improving objectively measured adherence (i.e., MEMS caps) over a 6-week period via a pilot RCT with 40 HIV+/METH+ assigned to the iTAB intervention and 20 HIV+/METH+ assigned to a psychoeducational control. Predictors of nonadherence including frequency of METH use, neuropsychological impairment, and mood will be examined to determine whether iTAB is better able to compensate for these factors associated with nonadherence as compared to CTRL. Further refinement to the iTAB intervention will be made in order to pursue a large-scale R01 using our tailored intervention.
The purpose of the study is to see if ImmunoLin® will reduce the frequency of bowel movements and gastrointestinal (GI) symptoms in HIV volunteers with persistent GI symptoms. The study will also examine the effect of ImmunoLin® on the bacteria in the gut and the immune system in gut tissue as well as in the blood.
