Filter by:The advances in treatment to prevent maternal HIV transmission to neonates have been groundbreaking. As a result, the number of new perinatally-infected children in the U.S. is now small. Subsequent improvements in the treatment of HIV-infected infants and children have been equally remarkable, ensuring that most previously infected American children have survived and are approaching adolescence. In addition, the number of HIV-infected adolescents worldwide is growing substantially in both resource-poor countries and in countries with increasing levels of health care. Therefore, there is a global cohort of children who have been living with HIV infection since birth who are aging into adolescence. Little is definitively known about the impact of HIV infection and its treatment on the maturation process in these children. AMP is a prospective cohort study designed to define the impact of HIV infection and antiretroviral therapy on pre-adolescents and adolescents with perinatal HIV infection. Domains to be investigated include growth and sexual maturation, metabolic risk factors for cardiovascular disease, cardiac function, bone health, neurologic, neurodevelopment, language, hearing and behavioral function, and sexually transmitted infections (STI).
The purpose of this project is to compare the effect of a family-based HIV prevention program to the effect of an adolescent-only health promotion program on adolescent HIV risk and marijuana use among adolescents enrolled in the Juvenile Drug Court (JDC) of the Rhode Island Family Court.
The investigators are conducting a double-blind, placebo controlled,randomized trial of multivitamin supplements(containing B-vitamins, C, and E) to determine their efficacy in slowing disease progression, indicated by increased CD4 count, weight gain, and improved quality of life, and decreased morbidity, mortality, and drug-related adverse events (i.e. peripheral neuropathy, anemia, and diarrhea). The investigators hypothesize that daily multivitamin supplementation will: (1) improve immune reconstitution; (2) improve weight gain, and (3) improve quality of life.
Project Aware is a randomized controlled clinical trial in which individuals seeking medical or health services at sexually transmitted disease (STD) clinics are recruited to participate in a multi-center HIV testing and counseling study. The investigators will assess the relative effectiveness and cost-effectiveness of (1) on-site HIV rapid testing with brief, participant-tailored prevention counseling vs. (2) on-site HIV rapid testing with information only. The investigators will evaluate the effect of counseling on one primary outcome: STI incidence. Secondary outcomes will be reduction of sexual risk behaviors, substance use during sex (i.e., being under the influence during sex) and cost and cost effectiveness of counseling and testing. Participants will be assessed for sexually transmitted infections, HIV testing history and sexual and drug use risk behaviors at baseline and at 6-months follow-up. Approximately 5,000 individuals seeking medical or health services from approximately 9 STD clinics throughout the United States will be randomized. These individuals will be 18 years of age or older and efforts will be made to recruit a sample of study participants that reflects the proportion of minorities and gender in the STD clinic performance sites from which the investigators are recruiting.
The investigators hypothesize that switching to a regimen based on efavirenz will be as effective and safe as remaining on a regimen based on Lopinavir/ritonavir for HIV-infected children. The investigators propose an unblinded randomized clinical trial to evaluate a simplification, protease-inhibitor (PI)-sparing treatment strategy among nevirapine (NVP)-exposed HIV-infected children treated initially with lopinavir/ritonavir (LPV/r). HIV-infected children aged 3-5 years, who have a history of exposure to NVP as part of prevention of mother-to-child HIV transmission (PMTCT), initiated LPV/r-based therapy in the first 36 months of life or who were enrolled on the control arm of Neverest 2 and who are virally suppressed with a viral load < 50 copies/ml will be included. These children will be randomized to either substitute efavirenz (EFV) for LPV/r or to continue on their LPV/r-based regimen. Eight weeks prior to the primary randomization, eligible children will also be randomized to either remain on stavudine (D4T) or switch to abacavir (ABC). Children will be followed with regular viral load and other clinical tests for 48 weeks after the primary randomization. Children in the experimental arm who have breakthrough viremia (-defined as two subsequent viral loads > 1000 copies/ml) on the EFV-based regimen will reinitiate the LPV/r regimen. The primary objective is to test whether the durability of viral suppression is equivalent when children are switched to EFV-based therapy. The primary study endpoint is failure to have HIV RNA < 50 copies/ml and/or confirmed viremia >1000 copies/ml. Secondary aims include comparison of immune preservation, toxicities, selection of resistance mutations, and adherence across the two arms. Antiretroviral drug concentrations and adherence will be investigated as possible explanations for the success and/or failure of this simplification regimen. The overall goal of the study is to contribute to the evidence base to allow expansion of treatment options for HIV-infected children in low resource settings.
Spirulina, a widely used food supplement, improves the lipid profile and glycemic control in people living with diabetes, suggesting that it could have some effects on insulin sensitivity. Since HIV-infected patients develop metabolic abnormalities due to the virus and/or to antiretroviral (ARV) drugs, the investigators therefore proposed to evaluate the effect that spirulina can have on HIV/HAART-associated insulin resistance
The purpose of this study is to examine the efficacy of a brief culturally appropriate and theory-based parental communication intervention designed to improve parent-adolescent sexual communication and reduce adolescent sexual risk behavior.
The purpose of this study is to conduct a randomized control trial of a behavioral intervention delivered by counselors via telephone to determine if this is an efficacious method for improving medication adherence and health-related quality of life for persons who are 50 and older and living with HIV/AIDS and other chronic conditions.
The null hypothesis is that there is a difference in the the relative rate and extent of absorption into the systemic circulation of Triomune and brand-name Stavudine/Lamivudine/Nevirapine in HIV-infected Africans and the alternative hypothesis is that there is no difference in the the relative rate and extent of absorption into the systemic circulation of Triomune and brand-name Stavudine/Lamivudine/Nevirapine in HIV-infected Africans. This is a non-inferiority study.
People with diabetes are at increased risk for atherosclerosis and have high CVD morbidity and mortality rates. Tools for detecting and quantifying atherosclerotic pro/regression in people with diabetes and other CVD risk factors lack sensitivity and specificity for molecular level events that occur during the early stages of atherogenesis. Inflammatory macrophage infiltration in the vessel endothelium is an early, molecular level proatherogenic event. Activated macrophages consume glucose at a high rate. Novel in vivo radiotracer PET/CT techniques have been developed to detect, image and quantify molecular level events like macrophage inflammation and glucose utilization (18FDG) in human vessels. We propose to develop and test this novel technique in the Center for Clinical Imaging Research (CCIR) at WUMS. We propose that HIV-infected people with significant CVD risk profiles are a suitable, unique human model for testing these novel imaging techniques. HIV-infected people taking anti-HIV medications develop insulin resistance, T2DM, dyslipidemia, central adiposity, and hypertension. HIV replicates in macrophages and represents a chronic proinflammatory condition. Recent data indicate that HIV+ CVD risk have greater risk for atherosclerosis and MI than HIV-negative people. To test feasibility, we hypothesize that: a.18FDG-PET/CT imaging will detect more macrophage glucose uptake and inflammation in the carotid and aorta arteries of HIV-infected people with CVD risk than in HIV-negative controls; b. radiotracer PET/CT measures of proatherogenic processes will correlate with carotid intima media thickness; a standard measure of carotid atherosclerotic burden. We propose to obtain pilot data that shows feasibility for a novel analytical approach that will expand capabilities for researchers interested in studying the links between diabetes, inflammation, and CVD in humans.
